Background: Hepatocellular Carcinoma (HCC) is the most common type of primary liver cancer, accounting for the majority of liver cancer cases. Hepatocellular Carcinoma not only exhibits high heterogeneity but also possesses an immune-suppressive tumor microenvironment that promotes tumor evasion, posing substantial difficulties for efficient therapy. Our aim is to utilize single-cell RNA transcriptome data to investigate the dynamic changes in the tumor microenvironment during the malignant progression of HCC, the communication among immune cells, and the marker genes associated with patient prognosis., Methods: We constructed expression matrices from open single-cell RNA transcriptome data (GSE149614) of HCC patients (representing stages I-IV), establishing single-cell RNA transcriptional atlases for different stages of HCC progression. For each stage, we conducted cell subgroup analysis to identify cell types at each stage. Horizontally, we explored the dynamic changes of the same cell type across different stages, performing trajectory analysis and prognosis analysis. Vertically, we investigated pairwise comparisons of different stages of HCC progression, probing the dynamic alterations in tumor microenvironment immune cell signaling pathways. Finally, potential drugs for the treatment of HCC were predicted based on relevant genes., Findings: As the HCC advances towards increased malignancy, there is a shift in the predominant composition of the tumor microenvironment, with a decline in the dominance of hepatic cells. Tumor-infiltrating immune cells migrate and accumulate within the tumor microenvironment, where T cells and myeloid cells display distinct patterns of change. Genes associated with cancer-associated fibroblasts (CAFs) and T cells are correlated with adverse patient outcomes. In the late stages of HCC, the tumor microenvironment is infiltrated by more myeloid-derived suppressor cells (MDSCs), and a prognostic model constructed based on genes related to myeloid cells can predict patient outcomes. Additionally, in the analysis of transcription factors, YY1 and MYC are found to be highly expressed. Cell communication analysis among tumor-infiltrating immune cells reveals significant differences in the main signaling pathways at different stages of HCC progression. Finally, drug sensitivity analysis based on key genes identifies Acetalax, Allopurinol, and Amonafide as potential candidates for HCC treatment., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author(s).

Emerging studies have examined the effectiveness of combined exercise and cognitive intervention (combined intervention) on the cognitive function of older adults with MCI, but the conclusions remain disputed. Our study aimed to comprehensively examine the efficacy of the combined intervention on cognitive and physical function in older adults with MCI. PubMed, Cochrane Library, EMBASE, and PsycINFO were retrieved to identify the relevant articles. Twelve eligible studies were included, and the results showed that combined intervention significantly improved global cognition SMD = 0.26, 95% CI [0.14-0.39], p<0.0001), executive function (SMD = 0.40, 95% CI [0.25-0.56], p < 0.00001), memory (SMD = 0.30, 95% CI [0.22-0.39], p <0.00001), and gait performance (SMD = 0.32, 95% CI [0.03-0.62], P = 0.03) compared to the control group. Combined intervention significantly improved executive function compared to single exercise intervention while not showing a statistically significant difference compared to single cognitive intervention. Moreover, no significant difference was observed between simultaneously and sequentially combined intervention. The finding indicated that combined intervention is efficacious in improving global cognition and selectively enhancing cognitive domains and physical function in older adults with MCI. More research with robust designs should be conducted, particularly involving comparisons with single interventions and different types of combined interventions., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Yi et al.

m -Trifluoromethylbenzene (FB) groups have been widely employed in various fields; however, no studies have reported the use of FB in side chains to enhance the carrier mobility and molecular doping of conjugated polymers. In this study, based on density functional theory (DFT) calculations, we discovered that FB groups can effectively bind to [FeCl 4 ] - , the counterion of the p-type dopant FeCl 3 , thereby increasing doping ability. Consequently, FB groups were incorporated into the side chains of thiophene-diketopyrrolopyrrole-based donor-acceptor (D-A)-conjugated polymers, and a series of random conjugated polymers were synthesized (denoted as PDPPFB- x , where x represents the molar ratio of the FB side chain). The findings revealed that an appropriate number of FB groups can decrease the π-π stacking distances, enhance the films' crystallinity, and consequently improve the charge transfer ability. Furthermore, after doping with FeCl 3 , the UV-vis-NIR spectra indicated that the doping efficiency was augmented by increasing the molar fraction of the FB side chain. Among these polymers, PDPPFB-10 exhibited the highest conductivity and power factor, which were 2.0 and 1.5 times higher than those of PDPPFB-0, respectively. These results illustrated a straightforward molecular design strategy for enhancing the crystallinity and conductivity of conjugated polymers, thereby expanding the way to optimize their thermoelectric performance.

Fatty acid desaturases (FADs) are enzymes that transform carbon‑carbon single bonds into carbon‑carbon double bonds within acyl chains, resulting in the production of unsaturated FAs (UFAs). They are crucial for plant growth, development, and adaptation to environmental stress. In our research, we identified 40 FAD candidates in the Salix matsudana genome, grouping them into seven categories. Exon-intron structures and conserved motifs of SmFADs within the same group showed significant conservation. Cis-element analysis revealed SmFADs are responsive to hormones and stress. Additionally, GO and KEGG analyses linked SmFADs closely with lipid biosynthesis and UFA biosynthesis, which were crucial for the plant's response to environmental stresses. Notably, the SmFAB2.4, SmADS1, SmFAD7.5, and SmFAD8.2 were predicted to participate in submergence tolerance, whereas SmFAD8.1 and SmFAD7.1 played an essential role in salt stress response. The diverse expression profiles of SmFADs across willow varieties, in various tissues, and throughout the willow bud development stages revealed a spectrum of functional diversity for these genes. Moreover, specific SmFADs might play a crucial role in callus development and the response to culturing conditions in various willow cultivars. This research underscored the importance of SmFAD profiles and functions and identified potential genes for enhancing forest resilience., Competing Interests: Declaration of competing interest The authors declared that they have no conflicts of interest to this work.

The bioaccumulation of heavy metals due to metallurgical and smelting activities threatens human health. Although microbial-induced carbonate/phosphate precipitation (MICP/MIPP) technology has been applied to heavy metal remediation, the relative merits of MICP and MIPP, especially under extreme pH environments, have not yet been documented. In this study, Sporosarcina pasteurii (SP)-based MICP and Bacillus megaterium (BM)-based MIPP were applied to immobilize lead (Pb) in aqueous solution and loess soil. The results showed that the BM retained a strong phosphorolysis ability when under strongly acidic conditions, while the ureolysis ability of SP approached zero. Furthermore, the bioprecipitates obtained under BM-based MIPP had a denser appearance, presumably due to the enrichment of calcite and apatite crystals. The results also showed that Pb immobilization was achieved through bacterial adsorption, the chelate function of sodium glycerophosphate (SGP), large organic matter complexation, and biomineralization through the MICP/MIPP mechanism. Under SP-based MICP, SP and large organic matter immobilized Pb 2+ at rates of 17.6 % and 31.7 %, respectively, while under BM-based MIPP, BM, organic matter, and SGP immobilized Pb 2+ at rates of 21.5 %, 23.4 %, and 48.5 % respectively. The MICP and MIPP mechanisms dominated Pb immobilization at rates of 78.6 % and 99.6 %, respectively., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

Inappropriate handling of lead (Pb)-containing wastewater that is produced as a result of smelting activities threatens the surrounding environment and human health. The microbial-induced phosphate precipitation (MIPP) technology was applied to immobilize Pb 2+ in an aqueous solution considering bacterial phosphorolysis ability and Ca-mediated alleviation of lead toxicity. Pb immobilization was accompanied by sample characterization in order to explore the inherent mechanism that affected the immobilization efficiency. Results showed that Ca 2+ use elevated the immobilization efficiency through the prevention of bacterial physisorption and chemisorption, an enhancement to the phosphatase activity and the degree of SGP hydrolysis, and the provision of nucleation sites for Pb 2+ to attach. The formation of the Pb-GP complex helped the bacteria to maintain its activity at the commencement of catalyzing SGP hydrolysis. The nucleated minerals that were precipitated in a columnar shape through a directional stacking manner under MIPP featured higher chemical stability compared to non-nucleated minerals. As a result, there were three pathways, namely, bacterial physisorption, bacterial chemisorption, and substrate chelation, applied for Pb immobilization. The immobilization efficiency of 99.6% is achieved by precipitating bioprecipitates including Pb 5 (PO 4 ) 3 Cl, Pb 10 (PO 4 ) 6 Cl 2 , and Ca 2 Pb 3 (PO 4 ) 3 Cl. The findings accentuate the potential of applying the MIPP technology to Pb-containing wastewater remediation., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Objectives: As a novel imaging marker, pericoronary fat attenuation index (FAI) reflects the local coronary inflammation which is one of the major mechanisms for in-stent restenosis (ISR). We aimed to validate the ability of pericoronary FAI to predict ISR in patients undergoing percutaneous coronary intervention (PCI)., Materials and Methods: Patients who underwent coronary CT angiography (CCTA) before PCI within 1 week between January 2017 and December 2019 at our hospital and had follow-up invasive coronary angiography (ICA) or CCTA were enrolled. Pericoronary FAI was measured at the site where stents would be placed. ISR was defined as ≥ 50% diameter stenosis at follow-up ICA or CCTA in the in-stent area. Multivariable analysis using mixed effects logistic regression models was performed to test the association between pericoronary FAI and ISR at lesion level., Results: A total of 126 patients with 180 target lesions were included in the study. During 22.5 months of mean interval time from index PCI to follow-up ICA or CCTA, ISR occurred in 40 (22.2%, 40/180) stents. Pericoronary FAI was associated with a higher risk of ISR (adjusted OR = 1.12, p = 0.028). The optimum cutoff was - 69.6 HU. Integrating the dichotomous pericoronary FAI into current state of the art prediction model for ISR improved the prediction ability of the model significantly (△area under the curve =  + 0.064; p = 0.001)., Conclusion: Pericoronary FAI around lesions with subsequent stent placement is independently associated with ISR and could improve the ability of current prediction model for ISR., Clinical Relevance Statement: Pericoronary fat attenuation index can be used to identify the lesions with high risk for in-stent restenosis. These lesions may benefit from extra anti-inflammation treatment to avoid in-stent restenosis., Key Points: • Pericoronary fat attenuation index reflects the local coronary inflammation. • Pericoronary fat attenuation index around lesions with subsequent stents placement can predict in-stent restenosis. • Pericoronary fat attenuation index can be used as a marker for future in-stent restenosis., (© 2024.

The carbon‒oxygen balance has always been problematic in constructed wetlands (CWs), putting pressure on stable and efficient nitrogen removal. In this study, a novel partial siphon operational strategy was developed to further optimize the carbon and oxygen distributions of a partially saturated vertical flow CW (SVFCW) to enhance nitrogen removal. The removal performances of the partial siphon SVFCW (S-SVFCW) were monitored and compared with those of the SVFCWs at different partial siphon depths (15 cm, 25 cm and 35 cm) in both the warm and cold seasons. The results showed that the partial siphon operating strategy significantly facilitated the removal of ammonia and total nitrogen (TN) in both the warm and cold seasons. When the partial siphon depth was 25 cm, the S-SVFCWs had the highest TN removal efficiency in both the warm (71%) and cold (56%) seasons, with an average improvement of 46% and 52%, respectively, compared with those of the SVFCWs. The oxidation‒reduction potential (ORP) results indicated that richer OPR environments and longer hydraulic detention times were obtained in the S-SVFCWs, which enriched the denitrification bacteria. Microbial analysis revealed greater nitrification and denitrification potentials in the unsaturated zone with enriched functional genes (e.g., amo&#95;AOA, amo&#95;AOB, nxrA and nirK), which are related to nitrification and denitrification processes. Moreover, the strengthening mechanism was the intensified oxygen supply and carbon utilization efficiency based on the cyclic nitrogen profile analysis. This study provides a novel partial siphon operational strategy for enhancing the nitrogen removal capacity of SVFCWs without additional energy or land requirements., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Cisplatin is a widely used chemotherapeutic drug that can induce ovarian damage. Icariin (ICA), a natural antioxidant derived from Epimedium brevicornum Maxim., has been found to protect against organ injury. The aim of the present study was to investigate whether ICA can exert an ovarian-protective effect on cisplatin induced premature ovarian failure (POF) and the underlying mechanism involved. The preventive effect of ICA was evaluated using body weight, the oestrous cycle, ovarian histological analysis, and follicle counting. ICA treatment increased body weight, ovarian weight, and the number of follicles and improved the oestrous cycle in POF mice. ICA reduced cisplatin-induced oxidative damage and upregulated the protein expression levels of Nrf2, GPX4 and HO-1. Moreover, ICA reduced the expression levels of Bax and γH2AX and inhibited ovarian apoptosis. In addition, ICA activated the Nrf2 pathway in vitro and reversed changes in the viability of cisplatin-induced KGN cells, reactive oxygen species (ROS) levels, lipid peroxidation, and apoptosis, and these effects were abrogated when Nrf2 was knocked down or inhibited. Molecular docking confirmed that ICA promotes the release of Nrf2 by competing with Nrf2 for binding to Keap1. The inhibitory effects of ICA on cisplatin-induced oxidative stress, ferroptosis, and apoptosis may be mediated by its modulatory effects on the Nrf2 pathway, providing a novel perspective on the potential mechanisms by which ICA prevents POF., (© 2024.

Rationale and Objectives: The aim of this study was to develop and validate a nomogram for predicting emergent conversion to general anaesthesia (GA) in stroke patients during thrombectomy., Methods: In this retrospective study, 458 patients (320 and 138 were randomised into the training and validation cohorts) were enroled. Univariable and multivariable logistic regression analyses were employed to identify risk factors for emergent conversion to GA. Subsequently, a nomogram was constructed based on the identified risk factors. The discriminative ability, calibration, and clinical utility of the nomogram were assessed in both the training and validation cohorts using receiver operating characteristic (ROC) curve analysis, Hosmer-Lemeshow test, and decision curve analysis (DCA)., Results: The emergent conversion to GA occurred in 56 cases (12.2%). In the training cohort, four independent predictors of emergent conversion to GA were identified and incorporated into the nomogram: core infarct volume > 70 mL, severe aphasia, severe cerebral vessel tortuosity, and vertebrobasilar occlusion. The ROC curves illustrated area under curve values of 0.931 (95% CI: 0.863-0.998) and 0.893 (95% CI: 0.852-0.935) for the training and validation cohorts, respectively. Hosmer-Lemeshow testing resulted in average absolute errors of 0.028 and 0.031 for the two cohorts. DCA demonstrated the nomogram's exceptional utility and accuracy across a majority of threshold probabilities., Conclusion: The constructed nomogram displayed promising predictive accuracy for emergent conversion to GA in stroke patients during thrombectomy, thereby providing potential assistance for clinical decision-making., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Association of University Radiologists.

In the realm of ornamental horticulture, crape myrtle (Lagerstroemia indica) stands out for its aesthetic appeal, attributed largely to its vibrant flowers and distinctive branching architecture. This study embarked on a comprehensive exploration of the gibberellin oxidase (GAox) gene family in crape myrtle, illuminating its pivotal role in regulating GA levels, a key determinant of plant developmental processes. We identified and characterized 36 LiGAox genes, subdivided into GA2ox, GA3ox, GA20ox, and GAox-like subgroups, through genomic analyses. These genes' evolutionary trajectories were delineated, revealing significant gene expansions attributed to segmental duplication events. Functional analyses highlighted the divergent expression patterns of LiGAox genes across different crape myrtle varieties, associating them with variations in flower color and branching architecture. Enzymatic activity assays on selected LiGA2ox enzymes exhibited pronounced GA2 oxidase activity, suggesting a potential regulatory role in GA biosynthesis. Our findings offered a novel insight into the molecular underpinnings of GA-mediated growth and development in L. indica, providing a foundational framework for future genetic enhancements aimed at optimizing ornamental traits., Competing Interests: Declaration of competing interest The authors declared that they have no conflicts of interest to this work.

Removal of heavy metals using the electrokinetic (EK) remediation technology is restricted by soils containing a fraction of clay particles above 12%. Furthermore, it is also affected by hydroxide precipitation (focusing phenomenon) close to the cathode. A modified EK reactor containing a permeable reactive barrier (PRB) was proposed herein where the enzyme-induced carbonate precipitation (EICP) treatment was incorporated into the PRB. Despite that, NH 4 + -N pollution induced by the urea hydrolysis resulting from the EICP treatment causes serious threats to surrounding environments and human health. There were four types of tests applied to the present work, including CP, TS1, TS2, and TS3 tests. CP test neglected the bio-PRB, while TS1 test considered the bio-PRB. TS2 test based on TS1 test tackled NH 4 + -N pollution using the struvite precipitation technology. TS3 test based on TS2 test applied EDDS to enhance the removal of Cu and Pb. In CP test, the removal efficiency applied to Cu and Pb removals was as low as approximately 10%, presumably due to the focusing phenomenon. The removal efficiency was elevated to approximately 24% when the bio-PRB and the electrolyte reservoir were involved in TS1 test. TS2 test indicated that the rate of struvite precipitation was 40 times faster than the ureolysis rate, meaning that the struvite precipitate had sequestered NH 4 + before it started threatening surrounding environments. The chelation between Cu 2+ and EDDS took place when EDDS played a part in TS3 test. It made Cu 2+ negatively surface charged by transforming Cu 2+ into EDDSCu 2- . The chelation caused those left in S4 and S4 to migrate toward the bio-PRB, whereas it also caused those left in S1 and S2 to migrate toward the anode. Due to this reason, the fraction of Cu 2+ removed by the bio-PRB and the electrolyte reservoir is raised to 32% and 26% respectively, and the fraction of remaining Cu was reduced to 41%. Also, the removal efficiency applied to Pb removal was raised to 50%. Results demonstrate the potential of struvite and EDDS-assisted EK-PRB technology as a cleanup method for Cu- and Pb-contaminated loess., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

DnaJs/Hsp40s/JPDs are obligate co-chaperones of heat shock proteins (Hsp70), performing crucial biological functions within organisms. A comparative genome analysis of four genomes (Vitis vinifera, Eucalyptus grandis, Lagerstroemia indica, and Punica granatum) revealed that the DnaJ gene family in L. indica has undergone expansion, although not to the extent observed in P. granatum. Inter-genome collinearity analysis of four plants indicates that members belonging to Class A and B are more conserved during evolution. In L. indica, the expanded members primarily belong to Class-C. Tissue expression patterns and the biochemical characterization of LiDnaJs further suggested that DnaJs may be involved in numerous biological processes in L. indica. Transcriptome and qPCR analyses of salt stressed leaves identified at least ten LiDnaJs that responded to salt stress. In summary, we have elucidated the expansion mechanism of the LiDnaJs, which is attributed to a recent whole-genome triplication. This research laid the foundation for functional analysis of LiDnaJs and provides gene resources for breeding salt-tolerant varieties of L. indica., (© 2024.

Modern metallurgical and smelting activities discharge the lead-containing wastewater, causing serious threats to human health. Bacteria and urease applied to microbial-induced carbonate precipitation (MICP) and enzyme-induced carbonate precipitation (EICP) are denatured under high Pb 2+ concentration. The nano-hydroxyapatite (nHAP)-assisted biomineralization technology was applied in this study for Pb immobilization. Results showed that the extracellular polymers and cell membranes failed to secure the urease activity when subjected to 60 mM Pb 2+ . The immobilization efficiency dropped to below 50% under MICP, whereas it due to a lack of extracellular polymers and cell membranes dropped to below 30% under EICP. nHAP prevented the attachment of Pb 2+ either through competing with bacteria and urease or promoting Ca 2+ /Pb 2+ ion exchange. Furthermore, CO 3 2- from ureolysis replaced the hydroxyl (-OH) in hydroxylpyromorphite to encourage the formation of carbonate-bearing hydroxylpyromorphite of higher stability (Pb 10 (PO 4 ) 6 CO 3 ). Moreover, nHAP application overcame an inability to provide nucleation sites by urease. As a result, the immobilization efficiency, when subjected to 60 mM Pb 2+ , elevated to above 80% under MICP-nHAP and to some 70% under EICP-nHAP. The findings highlight the potential of applying the nHAP-assisted biomineralization technology to Pb-containing water bodies remediation., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

Ovarian aging leads to infertility and birth defects. We aimed to clarify the role of Indole-3-carbinol (I3C) in resistance to oxidative stress, apoptosis, and fibrosis in ovarian aging. I3C was administered via intraperitoneal injection for 3 weeks in young or old mice. Immunohistochemistry; Masson, Sirius red, and TUNEL staining; follicle counting; estrous cycle analysis; and Western blotting were used for validating the protective effect of I3C against ovarian senescence. Human granulosa-like tumor cell line and primary granulosa cells were used for in vitro assay. The results indicated that I3C inhibited ovarian fibrosis and apoptosis while increasing the number of primordial follicles. Mechanistic studies have shown that I3C promoted the nuclear translocation of nuclear factor-erythroid 2-related factor (Nrf2) and upregulated the expression of heme oxygenase 1 (HO-1). Additionally, I3C increased cell viability and decreased lactate dehydrogenase, malondialdehyde, reactive oxygen species and JC-1 levels. Furthermore, the antioxidant effect of I3C was found to be dependent on the activation of Nrf2 and HO-1, as demonstrated by the disappearance of the effect upon inhibition of Nrf2 expression. In conclusion, I3C can alleviate the ovarian damage caused by aging and may be a protective agent to delay ovarian aging., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

Gibberellin oxidases (GAoxs) identified from many species play indispensable roles in GA biosynthesis and GA signal transduction. However, there has been limited research conducted on the GAox family of Salix matsudana, a tetraploid ornamental tree species. Here, 54 GAox genes were identified from S. matsudana and renamed as SmGA20ox1-22, SmGA2ox1-24, SmGA3ox1-6, and SmGAox-like1/2. Gene structure and conserved motif analysis showed that SmGA3ox members possess the 1 intron and other SmGAoxs contain 2-3 introns, and motif 1/2/7 universally present in all SmGAoxs. A total of 69 gene pairs were identified from SmGAox family members, and the Ka/Ks values indicated the SmGAoxs experience the purifying selection. The intra species collinearity analysis implied S. matsudana, S. purpurea, and Populus trichocarpa have the close genetic relationship. The GO analysis suggested SmGAoxs are dominantly involved in GA metabolic process, ion binding, and oxidoreductase activity. RNA-sequencing demonstrated that some SmGAoxs may play an essential role in salt and submergence stresses. In addition, the SmGA20ox13/21 displayed the dominant vitality of GA20 oxidase, but the SmGA20ox13/21 still possessed low activities of GA2 and GA3 oxidases. This study can contribute to reveal the regulatory mechanism of salt and submergence tolerance in willow., Competing Interests: Declaration of competing interest The authors declare no conflicts of interest., (Copyright © 2024 Elsevier B.V.

Persicaria capitata was a frequently used Hmong medicinal flora in China. In this study, one new phenolic compound, capitaone A ( 1 ) together with 20 known ones, were isolated from the whole herb of P. capitata . Among them, 7 components ( 4 , 9 - 11 , 15 - 16 , 20 - 21 ) were discovered from P. capitata for the first time. Their chemical structures were elucidated on the basis of extensive NMR and MS spectrum. Furthermore, three compounds ( 15 , 20 , 21 ) displayed remarkable cytotoxic activities against two human cancer cell lines (A549 and HepG2).

Background: Lagerstroemia indica is a widely cultivated ornamental woody shrub/tree of the family Lythraceae that is used as a traditional medicinal plant in East Asia and Egypt. However, unlike other ornamental woody plants, its genome is not well-investigated, which hindered the discovery of the key genes that regulate important traits and the synthesis of bioactive compounds., Results: In this study, the genomic sequences of L. indica were determined using several next-generation sequencing technologies. Altogether, 324.01 Mb sequences were assembled and 98.21% (318.21 Mb) of them were placed in 24 pseudo-chromosomes. The heterozygosity, repeated sequences, and GC residues occupied 1.65%, 29.17%, and 38.64% of the genome, respectively. In addition, 28,811 protein-coding gene models, 327 miRNAs, 552 tRNAs, 214 rRNAs, and 607 snRNAs were identified. The intra- and interspecies synteny and Ks analysis revealed that L. indica exhibits a hexaploidy. The co-expression profiles of the genes involved in the phenylpropanoid (PA) and flavonoid/anthocyanin (ABGs) pathways with the R2R3 MYB genes (137 members) showed that ten R2R3 MYB genes positively regulate flavonoid/anthocyanin biosynthesis. The colors of flowers with white, purple (PB), and deep purplish pink (DPB) petals were found to be determined by the levels of delphinidin-based (Dp) derivatives. However, the substrate specificities of LiDFR and LiOMT probably resulted in the different compositions of flavonoid/anthocyanin. In L. indica, two LiTTG1s (LiTTG1-1 and LiTTG1-2) were found to be the homologs of AtTTG1 (WD40). LiTTG1-1 was found to repress anthocyanin biosynthesis using the tobacco transient transfection assay., Conclusions: This study showed that the ancestor L. indica experienced genome triplication approximately 38.5 million years ago and that LiTTG1-1 represses anthocyanin biosynthesis. Furthermore, several genes such as LiDFR, LiOMTs, and R2R3 LiMYBs are related to anthocyanin biosynthesis. Further studies are required to clarify the mechanisms and alleles responsible for flower color development., (© 2024. The Author(s).)

Temperature is an important factor affecting the water purification performance of constructed wetland (CW). In the previous study, the combined measures of Iris sibirica and aeration at the bottom of the first quarter filtration chamber could improve the pollutant removal capacity of CW at low temperature. However, the mechanism between the combined measures of Iris sibirica and aeration on enhancing the performance of domestic sewage treatment is unclear. Our study aims to provide scientific validation for the combined measure through monitoring the concentrations of dissolved oxygen (DO), chemical oxygen demand (COD Cr ), ammonia nitrogen (NH 4 + -N), and total nitrogen (TN) along the water flow pathway of the CW and measuring the superoxide dismutase (SOD) activities of the plants and the abundance of nitrogen cycle-related microbial functional genes in the substrates of CW to explore the mechanism of combined measures promoting the removal efficiency of the CW under low-temperature stress. Results showed that aerating at the bottom of the first quarter filtration chamber increased DO concentration in the front part of the CW, which benefited the aerobic removal of pollutants and the activities of microorganisms, and the removal COD Cr and NH 4 + -N occurred mainly in the front part of the CW. SOD activities showed that I. sibirica had better resistance to low temperature than Canna indica did. The combined measures of I. sibirica and aeration activated the activities of microorganisms, increased the abundance of the denitrification process genes along the water flow pathway and formed a clear nitrification-denitrification zone in the CW, thus promoted the nitrogen removal efficiency at low temperature. Therefore, this study confirmed the feasibility of the combined measures from a mechanistic perspective., (© 2024.

Background and Objectives: Duodenal adenocarcinoma (DAC) is a rare tumor that is often accompanied by liver metastasis in advanced stages. The aim of this study was to evaluate the correlation between clinicopathological characteristics and survival in DAC patients with liver metastasis, and to explore appropriate treatment options., Methods: 482 DAC patients with liver metastasis were retrospectively identified from the Surveillance, Epidemiology and End Results (SEER) database (2011-2020). Univariate and multivariate Cox regression analyses were performed to explore the clinicopathological factors related to survival. The Kaplan-Meier method was used to identify the independent risk factors associated with survival., Results: The 1-year overall survival (OS) and cancer-specific survival (CSS) rates for the entire cohort were 25.4% and 28.3%, and the 5-year OS and CSS rates were 2.4% and 2.9% respectively. Univariable analysis and multivariate analysis identified chemotherapy and surgery as the independent risk factors for OS and CSS. Patients who underwent chemotherapy and surgery had better CSS and OS rates, whereas radiotherapy failed to improve outcomes., Conclusion: We identified several prognostic factors of DAC with liver metastasis. Chemotherapy and surgery can prolong the survival of DAC patients with liver metastasis, which lays the foundation for identifying the optimal treatment strategy., Competing Interests: All authors declare no conflicts of interest in this work., (© 2024 Zhu et al.)

Background: Annexin (ANN) is calcium (Ca 2+ )-dependent and phospholipid binding protein family, which is involved in plant growth and development and response to various stresses. However, little known about ANN genes were identified from crape myrtle, an ornamental horticultural plant widely cultivated in the world., Results: Here, 9 LiANN genes were identified from Lagerstroemia indica, and their characterizations and functions were investigated in L. indica for the first time. The LiANN genes were divided into 2 subfamilies. The gene structure, chromosomal location, and collinearity relationship were also explored. In addition, the GO annotation analysis of these LiANNs indicated that they are enriched in molecular functions, cellular components, and biological processes. Moreover, transcription factors (TFs) prediction analysis revealed that bHLH, MYB, NAC, and other TFs can interact with the LiANN promoters. Interestingly, the LiANN2/4/6-9 were demonstrated to play critical roles in the branching architecture of crape myrtle. Furthermore, the LiANN2/6/8/9 were differentially expressed under salt treatment, and a series of TFs regulating LiANN2/6/8/9 expression were predicted to play essential roles in salt resistance., Conclusions: These results shed light on profile and function of the LiANN gene family, and lay a foundation for further studies of the LiANN genes., (© 2024.

Objective: To explore the clinical effect of atorvastatin calcium combined with clopidogrel in the treatment of patients with transient ischemic attacks (TIAs) and its effect on blood lipids and platelets., Methods: Low-density lipoprotein cholesterol (LDL-C)], platelet-related parameters [prothrombin time (PT), activated partial thromboplastin time (APTT), platelet count (PLT)], incidence of cerebral infarction, and adverse reactions., Results: The clinical outcomes of the experimental group patients were significantly better than those of the control group patients ( p  < 0.05). The experimental group exhibited notably lower levels of TG, TC, and LDL-C compared to the control group ( p  < 0.05). Platelet-related indices-PT, APTT, and PLT-showed no significant differences between groups before and after treatment ( p  > 0.05). The incidence of cerebral infarction was notably lower in the experimental group ( p  < 0.005), while the occurrence of adverse reactions showed no significant difference between groups ( p  > 0.05)., Conclusion: Atorvastatin calcium combined with clopidogrel demonstrates a positive impact on individuals with TIAs by significantly lowering levels of LDL, total cholesterol, and triglycerides. However, it is noteworthy that platelet-related indices did not exhibit significant differences between the experimental and control groups. While the observed improvements in blood lipids are attributed to the effects of atorvastatin, the combination with clopidogrel did not show a substantial influence on platelet-related parameters. Thus, the overall therapeutic impact, particularly on platelet-related indices, may require further investigation and clarification. Despite these nuances, our findings suggest potential benefits in reducing the risk of adverse reactions and cerebral infarction, supporting the consideration of this approach for wider clinical use.

Given that the severity of the chemotherapy-induced ovarian damage, effective fertility preservation is a necessary part of the treatment process. Ferroptosis is a regulated cell death triggered by excessive phospholipid peroxidation caused by iron and the role of ferroptosis in chemotherapy-induced ovarian damage remains unclear. In this study, we demonstrated that cisplatin treatment caused the accumulation of iron ions which induced ferroptosis in ovarian tissue. And our results show that ferrostatin-1 was able to suppress the ovarian injury and granulosa cell death caused by cisplatin (Cis) in vivo and in vitro. At the same time, we observed significant changes in the expression levels of Acyl-CoA synthetase long-chain family member 4 (Acsl4) and glutathione peroxidase 4 (GPX4). Similarly, Rosiglitazone, an inhibitor of Acsl4, administration alleviated the ovary damage of the mice undergoing chemotherapy. Further mechanistic investigation showed that cisplatin increased the expression level of specificity protein 1 (SP1), and SP1 could bind to the promoter of Acsl4 to increased Acsl4 transcription. Overall, ferroptosis plays an important role in Cis induced ovarian injury, and inhibition of ferroptosis protects ovarian tissues from damage caused by cisplatin, and for the first time, we have identified the potential of Fer-1 and Rosi to protect ovarian function in female mice undergoing chemotherapy., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier B.V.

Introduction: It is encouraged to estimate the effectiveness of components within the enhanced recovery after surgery (ERAS) protocol through patient-reported outcomes, alongside doctor-reported outcomes and length of hospital stay. At present, studies on the contributions of optimal anaesthetic drugs within the ERAS protocol to patient-reported and doctor-reported outcomes are limited. Therefore, this study aims to pragmatically evaluate the effectiveness and safety of general anaesthesia (GA) with remimazolam tosilate within the ERAS protocol on intraoperative haemodynamics and postoperative recovery in adults undergoing elective surgeries, compared with propofol., Methods and Analysis: This study is a single-centre, randomised, blinded, positive-controlled, pragmatic clinical trial. A total of 900 patients, aged ≥18 years old, scheduled for an elective surgical procedure under GA will be included. Patients will be randomised in a 1:1 ratio to the remimazolam group (the GA with remimazolam tosilate within the ERAS protocol group) or propofol group (the GA with propofol within the ERAS protocol group), stratified by general surgery, thoracic surgery and other surgeries (including urological surgery and otolaryngology surgery). The primary outcomes include the 24-hour postoperative quality of recovery-40 score and the rate of intraoperative hypotension. Secondary endpoints include the rate of sedative hypotension requiring treatment, the haemodynamic profiles, the 72-hour postoperative quality of recovery-40 score, the functional anaesthetic capability, adverse events and complications, quality of life within 3 months as well as economic health outcomes., Ethics and Dissemination: This study protocol has been approved by the ethics committee of Guangdong Provincial People's Hospital (KY-H-2022-005-03-08). Dissemination plans will be presented at scientific meetings and in scientific publications., Trial Registration Number: ChiCTR2200062520., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Lead (Pb) accumulation can lead to serious threats to surrounding environments and damage to the liver and kidneys. In the past few years, microbial-induced carbonate precipitation (MICP) technology has been widely applied to achieve Pb immobilization due to its environmentally friendly nature. However, harsh pH conditions can cause the instability of the carbonate precipitation to degrade or dissolve, increasing the potential of Pb 2+ migration into nearby environments. In this study, microcapsule-based self-healing microbial-induced calcium carbonate (MICC) materials were applied to prevent Pb migration. The highest sporulation rate of 95.8% was attained at 7 g/L yeast extract, 10 g/L NH4Cl, and 3.6 g/L Mn 2+ . In the germination phase, the microcapsule not only prevented the bacterial spores from being threatened by the acid treatment but secured their growth and reproduction. Micro analysis also revealed that cerussite, calcite, and aragonite minerals were present, while extracellular polymeric substances (EPSs) were identified via Fourier transform infrared spectroscopy (FTIR). These results confirm their involvement in combining Pb 2+ and Ca 2+ . The immobilization efficiency of above 90% applied to MICC materials was attained, while it of below 5% applied to no MICC use was attained. The findings explore the potential of applying microcapsule-based self-healing MICC materials to prevent Pb ion migration when the calcium carbonate degrades under harsh pH conditions., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Inc.

Although the electrokinetic (EK) remediation has drawn great attention because of its good maneuverability, the focusing phenomenon near the cathode and low removal efficiency remain to be addressed. In this study, a novel EK reactor was proposed to remediate Cu and Pb contaminated loess where a biological permeable reactive barrier (bio-PRB) was deployed to the middle of the EK reactor. For comparison, three test configurations, namely, CG, TG-1, and TG-2, were available. CG considered the multiple enzyme-induced carbonate precipitation (EICP) treatments, while TG-1 considered both the multiple EICP treatments and pH regulation. TG-2 further considered NH 4 + recovery based on TG-1. CG not only improved Cu and Pb removals by the bio-PRB but also depressed the focusing phenomenon. TG-1 causes more Cu 2+ and Pb 2+ to migrate toward the bio-PRB and aggravates Cu and Pb removals by the bio-PRB, depressing the focusing phenomenon. TG-2 depressed the focusing phenomenon the most because Cu 2+ and Pb 2+ can combine with not only CO 3 2- but PO 4 3- . The removal efficiency of Cu and Pb is 34% and 36%, respectively. A NH 4 + recovery of about 100% is attained., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Ltd.

Background: Cuproptosis is a new type of programmed cell death involved in the regulation of neuroendocrine tumors, immune microenvironment, and substance metabolism. However, the role of cuproptosis-related genes (CRGs) in Hepatocellular carcinoma (HCC) remains unclear., Method: Through multiple bioinformatics analysis, we constructed a prognostic gene model and competing endogenous RNA (ceRNA) network. The correlation between CRGs and prognosis, immune infiltration, immune checkpoints, microsatellite instability (MSI) and tumor mutational burden (TMB) was analyzed by Kaplan-Meier curve, univariate Cox, multivariate regression, and Spearman's analysis in HCC patients. Besides, the qRT-PCR and immunohistochemistry assays were used to determine prognostic CRGs mRNA and protein expression in HCC., Results: We established a novel 3-gene signature related to CRGs for evaluating the prognosis of HCC patients. HCC patients with high risk scores had a poor prognosis with an area under the curve of 0.737, 0.646, and 0.634 on 1-year, 3-year, and 5-year receiver operating characteristic curves. Significant correlation was observed between prognostic CRGs and immune infiltration, immune checkpoints, MSI and TMB. We also developed five ceRNA networks to regulate the occurrence and progression of HCC. CDKN2A, DLAT, and PDHA1 protein expression was up-regulated in HCC versus normal tissues. Besides, the mRNA expression levels of CDKN2A, DLAT, GLS, and PDHA1 were elevated in the HCC cell lines compared to the normal liver cell lines., Conclusions: This novel prognostic CRGs signature could be accurately predict the prognosis of patients with HCC. The ceRNA regulatory network might be potential prognostic biomarkers and therapeutic targets for HCC patients.

Background: Breast cancer is the most common female malignant tumor type globally. The occurrence and development of breast cancer involve ferroptosis, which is closely related to its treatment. The development of breast cancer organoids facilitates the analysis of breast cancer molecular background and tumor biological behavior, including clinical pathological characteristics, drug response, or drug resistance relationship, and promotes the advancement of precision treatment for breast cancer. The three-dimensional (3D) cell culture of breast cancer MCF-7 organoid is more similar to the in vivo environment and thus obtains more realistic results than 2D cell culture. Our study examined the new mechanism of tamoxifen in treating breast cancer through breast cancer MCF-7 organoids., Methods: We used 3D cells to culture breast cancer MCF-7 organoid, as well as tamoxifen-treated MCF-7 and tamoxifen-resistant MCF-7 (MCF-7 TAMR) cells. We used transcriptome sequencing. We detected GPX4 and SLC7A11 protein levels using Western blotting and the content of ATP, glutathione, and ferrous ions using the Cell Counting Lite 3D Kit. We assessed cell viability using the Cell Counting Kit-8 (CCK-8) assay., Results: Tamoxifen significantly inhibited the growth of MCF-7 organoids and significantly induced ferroptosis in MCF-7 organoids. The ferroptosis inhibitor reversed the significant tamoxifen-induced MCF-7 organoid inhibition activity. Moreover, the ferroptosis activator enhanced the tamoxifen-induced MCF-7 TAMR cell activity inhibition., Conclusion: Our study revealed that ferroptosis plays an important role in tamoxifen-induced MCF-7 organoid cell death and provides a new research idea for precise treatment of breast cancer through an organoid model., (Copyright © 2023 Copyright: © 2023 Journal of Cancer Research and Therapeutics.)

Neuroinflammation mediated by microglia activation leads to various neurodegenerative and neurological disorders. In order to develop more and better options for this disorders, a series of 3,4-dihydrobenzo[b]oxepin-5(2H)-one derivatives (BZPs, 6-19) and novel 1,4,5,6-tetrahydrobenzo[2,3]oxepino[4,5-d]pyrimidin-2-amine derivatives (BPMs, 20-33) were synthesized and screened the anti-neuroinflamamtion effects. 3,5-bis-trifluoromethylphenyl-substituted BPM 29 showed more potent anti-neuroinflammatory activity and no toxicity to BV2 microglia cells in vitro. 29 significantly reduced the number of M1 phenotype of microglia cells, but significantly increased the number of M2 phenotype of microglia cells in lipopolysaccharide (LPS)-induced BV2 microglia cells. 29 significantly reduced the secretion of inflammatory cytokines (IL-18, IL-1β, TNF-α), but increased the secretion of anti-inflammatory cytokines (IL-10) from LPS-induced BV2 microglia cells. Also, 29 inhibited the NOD-like receptor NLRP3 inflammasome formation, and down-regulated the expression of M2 isoform of pyruvate kinase in LPS-induced BV2 microglia cells. In vivo, 29 reduced the neuroinflammation in cuprizone-induced inflammatory and demyelinating mice by reducing the expression of inducible nitric-oxide synthase, but increased the expression of CD206. Taken together, 29 might be a prospective anti-neuroinflammatory compound for neuroinflammatory and demyelinating disease by alleviating microglia activation., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023.

Wastewater, discharged in copper (Cu) mining and smelting, usually contains a large amount of Cu 2+ . Immobilizing Cu 2+ in aqueous solution and soils is deemed crucial in preventing its migration into surrounding environments. In recent years, the enzyme-induced carbonate precipitation (EICP) has been widely applied to Cu immobilization. However, the effect of Cu 2+ toxicity denatures and even inactivates the urease. In the present work, the biopolymer-assisted EICP technology was proposed. The inherent mechanism affecting Cu immobilization was explored through a series of test tube experiments and soil column tests. Results indicated that 4 g/L chitosan may not correspond to a higher immobilization efficiency because it depends as well on surrounding pH conditions. The use of Ca 2+ not only played a role in further protecting urease and regulating the environmental pH but also reduced the potential for Cu 2+ to migrate into nearby environments when malachite and azurite minerals are wrapped by calcite minerals. The species of carbonate precipitation that are recognized in the numerical simulation and microscopic analysis supported the above claim. On the other hand, UC1 (urease and chitosan colloid) and UC2 (urea and calcium source) grouting reduced the effect of Cu 2+ toxicity by transforming the exchangeable state-Cu into the carbonate combination state-Cu. The side effect, induced by 4 g/L chitosan, promoted the copper-ammonia complex formation in the shallow ground, while the acidic environments in the deep ground prevented Cu 2+ from coordinating with soil minerals. These badly degraded the immobilization efficiency. The Raman spectroscopy and XRD test results tallied with the above results. The findings shed light on the potential of applying the biopolymer-assisted EICP technology to immobilizing Cu ions in water bodies and sites., (© 2023.

With the development of high-power fuel cell vehicles, heat dissipation requirements have become increasingly stringent. Although conventional cooling techniques improve the heat dissipation capacity by increasing the fan rotating speed or radiator dimensions, high energy consumption and limited engine compartment space prevent their implementation. Moreover, the insufficient heat transfer capacity of existing coolants limits the enhancement of heat dissipation performance. Therefore, exploring novel coolants to replace traditional coolants is important. Nanofluids composed of nanoparticles and base liquids are promising alternatives, effectively improving the heat transfer capacity of the base liquid. However, challenges remain that prevent their use in fuel cell vehicles. These include issues regarding the nanofluid stability and cleaning, erosion and abrasion, thermal conductivity, and electrical conductivity. In this review, we summarize the nanofluid applications in oil-fueled, electric, and fuel cell vehicles. Subsequently, we provide a comprehensive literature review of the challenges and future research directions of nanofluids as coolants in fuel cell vehicles. This review demonstrates the potential of nanofluids as an alternative thermal management system that can facilitate transition toward a low-carbon, energy-secure economy. It will serve as a reference for researchers to focus on new areas that could drive the field forward.

Background: Abelson interactor Family Member 3 (ABI3) encodes protein that not only suppresses the ectopic metastasis of tumor cells but also hinders their migration. Although ABI3 had been found to modulate the advancement of diverse neoplasms, there is no comprehensive pan-cancer analysis of its effects. Methods: The transcriptomics data of neoplasm and normal tissues were retrieved from the Genomic Data Commons (GDC) data portal, and UCSC XENA database. To gather protein information for ABI3, Human Protein Atlas (HPA) and GeneMANIA websites were utilized. Additionally, Tumor Immune Single-cell Hub (TISCH) database was consulted to determine the primary cell types expressing ABI3 in cancer microenvironments. Univariate Cox regression approach was leveraged to evaluate ABI3's prognostic role across cancers. The Cbioportal and Gene Set Cancer Analysis (GSCA) website were leveraged to scrutinize the genomic landscape information across cancers. TIMER2.0 was leveraged to probe the immune cell infiltrations associated with ABI3 across cancers. The associations of ABI3 with immune-related genes were analyzed through Spearman correlation method. Gene Set Enrichment Analysis (GSEA) and Gene Set Variation Analysis (GSVA) were utilized to search associated biological pathways. The CellMiner database and molecular docking were implemented to identify potential interactions between the ABI3 protein and specific anticarcinogen. Findings: ABI3 expression and its ability to predict prognosis varied distinct tumor, with particularly high expression observed in Tprolif cells and monocytes/macrophages. Copy number variation (CNV) and methylation negatively correlated with ABI3 expression in the majority of malignancies. Corresponding mutation survival analysis indicated that the mutation status of ABI3 was strongly connected to the prognosis of LGG patients. ABI3 expression was linked to immunotherapeutic biomarkers and response in cancers. ESTIMATE and immune infiltrations analyses presented ABI3 association with immunosuppression. ABI3 was significantly correlated with immunoregulators and immune-related pathways. Lastly, prospective ABI3-targeted drugs were filtered and docked to ABI3 protein. Interpretation: Our study reveals that ABI3 acts as a robust tumor biomarker. Its functions are vital that could inhibit ectopic metastasis of tumor cells and modulate cellular adhesion and migration. The discoveries presented here may have noteworthy consequences for the creation of fresh anticancer suppressors, especially those targeting BRCA., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Sun, Cai, Xiong, Xie, Li, Xie, Luo, Hu, Zhong and Wang.)

Objectives: To evaluate the preoperative systemic immune-inflammation index (SII), advanced lung cancer inflammation index (ALI), neutrophil to lymphocyte ratio (NLR), and prognostic nutritional index (PNI) capacity to predict the prognosis of stage IA-IB endometrial carcinoma (EC) patients after operation, and establish a nomogram model to guide clinical practice., Methods: A total of 387 patients with EC (R0 resection, stage IA-IB) were assessed. Clinical information and the SII, NLR, ALI, and PNI values were obtained. The low and high ratio groups were separated using the receiver operating characteristic curve (ROC). Pearson's χ 2 -test or Fisher's exact test was used to determine their relationship with clinical variables. To determine the independent prognostic factors, Cox regression was utilized to do the univariate and multivariate survival analyses. The Kaplan-Meier method was used to draw the survival curve in our survival analysis. Depending upon the independent prognostic factors, the nomogram for Overall survival (OS) and Disease-free survival (DFS) nomogram was developed, and its discrimination ability was validated by the consistency index (C-index) and calibration curve., Results: Cox regression analysis revealed that FIGO staging, Ki-67 expression level, PNI, and ALI are independent prognostic factors for both OS and DFS. Then a novel predictive nomogram was developed, and its C-index value for OS and DFS was 0.829 and 0.814, respectively. The calibration curves demonstrated consistency amid the predicted prognosis using the developed nomogram and the actual observed outcomes., Conclusions: The ALI and PNI could serve as readily available prognostic indicators for OS and DFS prediction in stage IA-IB EC patients. The nomogram developed owned superior power for OS and DFS prediction in stage IA-IB EC patients, and it would assist clinical oncologists in accurately predicting the individual's OS and DFS., Competing Interests: None., (AJTR Copyright © 2023.)

Background: Colorectal cancer (CRC) is one of the most usual malignant tumors, and its incidence continues to rise. Our purpose was to explore the function and potential regulatory mechanisms of SALL1, a differentially methylated gene in CRC, in vivo and in vitro., Methods: Firstly, methylation differential gene SALL1 in CRC was screened and validated. SALL1 overexpression plasmids or SALL1 siRNAs were transfected in HT-29 and SW480 cells. Moreover, 10 μM T-5224 was added in SALL1-overexpressed CRC cells. CCK-8, flow cytometry and transwell assays were utilized to assess cell proliferation, cycle, migration, and invasion, respectively. Then CRC organoids were cultured. Next, HT-29 and SW480 cells transfected with SALL1 overexpression lentivirus were analyzed by transcriptome sequencing. Finally, in vivo tumorigenesis was used to analyze the effect of SALL1 overexpression on subcutaneous tumorigenesis in nude mice., Results: The methylation level of CpG island in SALL1 promoter was increased in CRC tissues and could distinguish tumor tissues. Overexpression of SALL1 accelerated proliferation, migration and invasion of HT-29 and SW480 cells, and silencing of SALL1 attenuated proliferation, migration and invasion of HT-29 and SW480 cells. Through analysis and validation, we found that overexpression of SALL1 also could upregulate p-p65 and p-JUN expressions. Besides, c-Fos/activator protein (AP)- 1 inhibitor (T-5224) could reverse the induction of CRC progression by SALL1 overexpression. In vivo, we also proved that overexpression of SALL1 significantly increased tumor volume, tumor weight, and p-JUN expression., Conclusions: SALL1 could promote the proliferation, migration, and invasion of CRC cells and activate phosphorylation of p65 and JUN., Competing Interests: Declaration of Competing Interest The authors have no relevant financial or non-financial interests to disclose., (Copyright © 2023 Elsevier GmbH.

Inappropriate handling of copper (Cu) and lead (Pb)-containing wastewater resulting from metallurgical and smelting industries in Northwest China encourages their migration to surrounding environments. Their accumulation causes damage to liver and kidney function. The electrokinetic (EK) technology is considered to be an alternative to traditional remediation technologies because of its great maneuverability. The EK remediation is accompanied by the electrode polarization and the focusing effect toward affecting removal efficiency. In this study, a nanocomposite hydrogel (NCH) electrode was proposed and applied to the EK remediation of Cu- and Pb-contaminated loess. The mechanical, adsorption capacity, adsorption kinetics, and electrochemical properties of the NCH electrode were investigated in detail, followed by microscopic analyses of Scanning Electron Microscope (SEM), Energy Dispersive X-ray Spectroscopy (EDS), and Raman spectrometer. Results showed that the enhancement of the mechanical properties of the NCH electrode was attributed to the crosslinks of graphene nanoparticles, calcium alginate, and hydrogen bonds, while the Cu or Pb adsorption by the NCH electrode was in a chemisorption manner. The second layer formation might address the increase in adsorption capacity with increasing temperature. These results highlight the relative merits of the NCH electrode and verify the potential of applying the NCH electrode to the EK remediation of Cu- and Pb-contamianted loess., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Ltd.

CBFs (C-repeat binding factors) have multiple functions in abiotic stress adaption; functional research of these genes will provide precious gene resources for plant genetic improvement. In this study, a homolog of AtCBFs, SmDREB A1-4 was cloned and its role in salt tolerance was explored. SmDREB A1-4 is a member of DREB A1 subgroup with 10 members. SmDREB A1-4 localized in nuclei and cytoplasm and expressed ubiquitously in different tissue and organs. The expression level of SmDREB A1-4 could be induced by NaCl treatment and the TC-rich repeat and DREB motif on the SmDREB A1-4 gene promoter may mediate the NaCl-induced expression pattern. Overexpression of the SmDREB A1-4 gene in Arabidopsis enhanced the salt tolerance of transgenic Arabidopsis lines, while down-regulated the expression level in Salix plantlets by Virus induce gene silencing decreased the salt tolerance capacity in VIGS Salix plantlets. Experiments data from both sides confirmed that SmDREB A1-4 is a positive regulatory factor in salt stress tolerance. qRT-PCR and luciferase reporter assays revealed that SOS1 and DREB2A are downstream genes of SmDREB A1-4. Through upregulating the expression of SOS1 and DREB2A, SmDREB A1-4 enhanced plant tolerance to salinity by regulating ion homeostasis, reduction of Na + /K + ratio, and improvement of proline biosynthesis. This research offers a potentially valuable gene resource for the stress-resistant varieties breeding of Salix matsudana in the future., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Masson SAS.

In the present study, several research methods were adopted, including literature retrieval, theoretical analysis, and qualitative research, and then the draft of the prognostic factors for the chronic post-surgical pain (CPSP) index system after video-assisted thoracoscopic surgery (VATS) for lung resection was constructed. A Delphi survey was used for the study of 24 experts in the field of pain from three different grade-A tertiary hospitals in Guangzhou, China. In the two rounds of survey, the experts rated these indicators for the importance and feasibility of measurement (round 1, n = 21 participants; round 2, n = 20). Finally, we calculated Kendall's W index as a measure of consensus. A general consensus was reached on predicting CPSP after VATS, consisting of 10 first-level domains and 64 second-level indicators, involving biological, psychological and social perspectives. This study provides a comprehensive draft of risk factors developed and identified by experts to inform research-based evidence on chronic pain. Increased clinical awareness and a full understanding of how to screen and identify people with CPSP problems may lead to earlier recognition of chronic pain and greater facilitation of professional prevention., Competing Interests: The authors have no conflicts of interest to disclose., (2023, National Center for Global Health and Medicine.)

Background Lipid-rich plaques detected with intravascular imaging are associated with adverse cardiovascular events in patients with non-ST-segment elevation (NSTE) acute coronary syndrome (ACS). But evidence about the prognostic implication of coronary CT angiography (CCTA) in NSTE ACS is limited. Purpose To assess whether quantitative variables at CCTA that reflect lipid content in nonrevascularized plaques in individuals with NSTE ACS might be predictors of subsequent nonrevascularized plaque-related major adverse cardiovascular events (MACEs). Materials and Methods In this multicenter prospective cohort study, from November 2017 to January 2019, individuals diagnosed with NSTE ACS (excluding those at very high risk) were enrolled and underwent CCTA before invasive coronary angiography (ICA) within 1 day. Lipid core was defined as areas with attenuation less than 30 HU in plaques. MACEs were defined as cardiac death, myocardial infarction, hospitalization for unstable angina, and revascularization. Participants were followed up at 6 months, 12 months, and annually thereafter for at least 3 years (ending by July 2022). Multivariable analysis using Cox proportional hazards regression models was performed to determine the association between lipid core burden, lipid core volume, and future nonrevascularized plaque-related MACEs at both the participant and plaque levels. Results A total of 342 participants (mean age, 57.9 years ± 11.1 [SD]; 263 male) were included for analysis with a median follow-up period of 4.0 years (IQR, 3.6-4.4 years). The 4-year nonrevascularized plaque-related MACE rate was 23.9% (95% CI: 19.1, 28.5). Lipid core burden (hazard ratio [HR], 12.6; 95% CI: 4.6, 34.3) was an independent predictor at the participant level, with an optimum threshold of 2.8%. Lipid core burden (HR, 12.1; 95% CI: 6.6, 22.3) and volume (HR, 11.0; 95% CI: 6.5, 18.4) were independent predictors at the plaque level, with an optimum threshold of 7.2% and 10.1 mm 3 , respectively. Conclusion In NSTE ACS, quantitative analysis of plaque lipid content at CCTA independently predicted participants and plaques at higher risk for future nonrevascularized plaque-related MACEs.

Recent studies have indicated that pyroptosis may participate in the regulation of tumorigenesis and immune microenvironment. However, the role of pyroptosis-related genes (PRGs) in pancreatic adenocarcinoma (PAAD) remains unclear. Through multiple bioinformatics analysis, we constructed a prognostic gene model and competing endogenous RNA network. The correlation between PRGs and prognosis, immune infiltration, immune checkpoints, and tumor mutational burden was analyzed by Kaplan-Meier curve, univariate Cox, multivariate regression, and Spearman's analysis in PAAD patients. The qRT-PCR, Western blotting, CCK-8, Wound healing, and Transwell assay were applied to examine the role of CASP6 in PANC-1 cell. Thirty-one PRGs were upregulated in PAAD. Functional enrichment analysis revealed that the PRGs were mainly involved in pyroptosis, NOD-like receptor signaling pathway, and response to bacteria. We established a novel 4-gene signature related to PRGs for evaluating the prognosis of PAAD patients. Patients with PAAD in the low-risk group had a better prognosis than those in the high-risk group. The nomogram suggested that the 1-, 3-, and 5-years survival probability exhibited robust predictive performance. Significant correlation was observed between prognostic PRGs and immune infiltration, immune checkpoints, and tumor mutational burden. We first identified the potential competing endogenous RNA regulatory axis in PAAD: lncRNA PVT1/hsa-miR-16-5p/CASP6/CASP8. Moreover, knockdown of CASP6 dramatically inhibited the proliferation, migration, and invasion ability of PANC-1 cell in vitro. In conclusion, CASP6 could be a potential biomarker, promoting the occurrence and progression in PAAD. The lncRNA PVT1/hsa-miR-16-5p/CASP6/CASP8 regulatory axis plays an vital role in regulating the anti-tumor immune responses for PAAD., (© 2023. The Author(s).)

Ethnopharmacology Relevance: Sophora flavescens Aiton, was a crucial source of Traditional Chinese Medicine (TCM) that has benefited human health for hundreds of years. Alkaloids and flavonoids were the major bioactive constituents from S. flavescens, which had been widely used for liver disease treatment in China. However, the liver-protective components of flavonoids from S. flavescens and their mechanism of action were not clear., Aim of the Study: This work aimed to evaluate the in vitro hepatoprotective activities of 35 flavonoids from S. flavescens and screen active compounds. Furthermore, it was conducted to demonstrate the hepatoprotective effects of a new active compound (kurarinol A, 1) was isolated by authors and the ethyl acetate (EtOAc) extract form S. flavescens against carbon tetrachloride (CCl 4 )-induced hepatic injury in Kunming (KM) mice, meanwhile revealed the potential mechanism., Materials and Methods: The 35 flavonoids from S. flavescens were co-incubated with HepG2 cells and treated with 0.35% CCl 4 for 6 h cell viability was measured by (3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium, inner salt) (MTS) assay. Then, in vivo animal experiments, the activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) in the serum were analyzed, the degree of hepatic injury was examined using hematoxylin-eosin (H&E) staining, the mRNA expression of Superoxide Dismutase 2 (SOD2), Nuclear factor E2-related factor 2 (Nrf2), heme oxygenase 1 (HO-1), Interleukin 6 (IL-6), Tumor Necrosis Factor-α (TNF-α), interleukin-1β (IL-1β), and the protein levels of nuclear factor-kappa B p65/p-p65 (NF-κB p65/p-p65), toll-like receptor 2 (TLR2), IL-1β and cyclooxygenase-2 (COX2) in hepatic tissues were detected., Results: The lavandulyl flavonoid (kurarinol A, 1) and the EtOAc extract from S. flavescens showed protective effects on CCl 4 -injured HepG2 cells, increasing cell viability from 24.5% to 61.3% and 91.8%, respectively. What's more, we found that treatment with kurarinol A (1) and the EtOAc extract lead to a significant reduction in hepatotoxicity in response to acute CCl 4 exposure. Compared with the model group, experimental results exhibited kurarinol A (10 mg/kg, i.p.) and the EtOAc extract (300 mg/kg, i.p.) could decrease the levels of AST, ALT, ALP and tissue damage. Further mechanistic investigations revealed that up-regulated the mRNA expression of SOD2, Nrf2, OH-1 and down-regulated the IL-1β in liver tissues, respectively. Additionally, Western blot analyses elucidated that inhibition of IL-1β, TLR2, COX-2, NF-κB (p65/p-p65) via TLR2/NF-κB signaling pathway by kurarinol A and the EtOAc extract contribute to its hepatoprotective activity., Conclusion: These findings demonstrated that the novel compound (kurarinol A, 1) possessed notable hepatoprotective activity against CCl 4 . It was confirmed that kurarinol A had a certain effect on mice with liver damage induced by CCl 4 , and its mechanism could be include inhibiting inflammation and reducing of oxidative stress reaction by regulating expression of related genes and proteins. Thus, kurarinol A could as a novel active agent that contributes to the hepatoprotective activity of S. flavescens for the treatment of live injury., Competing Interests: Declaration of competing interest The authors do not have any conflicts of interest to disclose., (Copyright © 2023 Elsevier B.V.

Lead (Pb) metal accumulation in surrounding environments can cause serious threats to human health, causing liver and kidney function damage. This work explored the potential of applying the MICP technology to remediate Pb-rich water bodies and Pb-contaminated loess soil sites. In the test tube experiments, the Pb immobilization efficiency of above 85% is attained through PbCO 3 and Pb(CO 3 ) 2 (OH) 2 precipitation. Notwithstanding that, in the loess soil column tests, the Pb immobilization efficiency decreases with the increase in depth and could be as low as approximately 40% in the deep ground. PbCO 3 and Pb(CO 3 ) 2 (OH) 2 precipitation has not been detected as the majority of Pb 2+ combines with -OH (hydroxyl group) when subjected to 500 mg/kg Pb 2+ . The alkaline front promotes the chemisorption of Pb 2+ with CO 3 2- reducing the depletion of quartz mineral close to the surface. However, OH - is in shortage in the deep ground retarding the Pb immobilization. The Pb immobilization efficiency thus decreases with the increase in depth. Quartz and albite minerals, when subjected to 16,000 mg/kg Pb 2+ , appear not to intervene in the chemisorption with Pb 2+ where the chemisorption of Pb 2+ with CO 3 2- plays a major role in the Pb immobilization. Compared to the nanoscale urease applied to the enzyme-induced carbonate precipitation (EICP) technology, the micrometer scale ureolytic bacteria penetrate into the deep ground with difficulty. The 'size' issue remains to be addressed in near future., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Ltd.

Inappropriate irrigation could trigger migration of heavy metals into surrounding environments, causing their accumulation and a serious threat to human central nervous system. Traditional site remediation technologies are criticized because they are time-consuming and featured with high risk of secondary pollution. In the past few years, the microbial-induced carbonate precipitation (MICP) is considered as an alternative to traditional technologies due to its easy maneuverability. The enzyme-induced carbonate precipitate (EICP) has attracted attention because bacterial cultivation is not required prior to catalyzing urea hydrolysis. This study compared the performance of lead (Pb) and copper (Cu) remediation using MICP and EICP respectively. The effect of the degree of urea hydrolysis, mass and species of carbonate precipitation, and chemical and thermodynamic properties of carbonates on the remediation efficiency was investigated. Results indicated that ammonium ion (NH 4 + ) concentration reduced with the increase in lead ion (Pb 2+ ) or copper ion (Cu 2+ ) concentration, and for a given Pb 2+ or Cu 2+ concentration, it was much higher under MICP than EICP. Further, the remediation efficiency against Cu 2+ is approximately zero, which is way below that against Pb 2+ (approximately 100%). The Cu 2+ toxicity denatured and even inactivated the urease, reducing the degree of urea hydrolysis and the remediation efficiency. Moreover, the reduction in the remediation efficiency against Pb 2+ and Cu 2+ appeared to be due to the precipitations of cotunnite and atacamite respectively. Their chemical and thermodynamic properties were not as good as calcite, cerussite, phosgenite, and malachite. The findings shed light on the underlying mechanism affecting the remediation efficiency against Pb 2+ and Cu 2+ ., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Wang, Cheng, Xue, Rahman, Xie and Hu.)

Plant non-specific lipid transfer proteins (nsLTPs) are small and have a broad biological function involved in reproductive development and abiotic stress resistance. Although a small part of plant nsLTPs have been identified, these proteins have not been characterized in poplar at the genomic level. A genome-wide characterization and expression identification of poplar nsLTP members were performed in this study. A total of 42 poplar nsLTP genes were identified from the poplar genome. A comprehensive analysis of poplar nsLTPs was conducted by a phylogenetic tree, duplication events, gene structures, and conserved motifs. The cis-elements of poplar nsLTPs were predicted to respond to light, hormone, and abiotic stress. Many transcription factors (TFs) were identified to interact with poplar nsLTP cis-elements. The tested poplar nsLTPs were expressed in leaves, stems, and roots, but their expression levels differed among tested tissues. Most poplar nsLTP expression levels were changed by abiotic stress, implying that poplar nsLTP may be involved in abiotic stress resistance. Network analysis showed that poplar nsLTPs are putative genes involved in fatty acid (FA) metabolism. This research provides sight into the further study to explain the regulatory mechanism of the poplar nsLTPs., Competing Interests: Declaration of competing interest The authors declare no conflicts of interest., (Copyright © 2023 Elsevier B.V.

Purpose: Prenatal exposure to famine has been linked to increased diabetes risk in adulthood. However, one fundamental issue to be addressed is that the reported famine-diabetes relation may be confounded by the age differences between the exposed and non-exposed groups. We aimed to determine the association between prenatal exposure to the Chinese famine of 1959-1962 and risk of diabetes by applying age well-controlled strategies., Methods: Among 20,535 individuals born in 1955-1966 who participated in the China Health and Nutrition Survey from 1997 to 2015, we constructed age-matched exposed vs. non-exposed groups to investigate the role of prenatal exposure to the Chinese famine of 1959-1962 in relation to diabetes. We also built a hierarchical age-period-cohort (HAPC) model to specifically examine the relation of famine to diabetes risk independent of age., Results: Compared to the age-balanced men in the non-exposed group, the exposed men born in 1961 had a 154% increased risk of diabetes [odds ratio (OR) 2.54 (95% CI 1.07-6.03), P = 0.04). In the HAPC analysis, the predicted probabilities of diabetes peaked in the 1961-birth cohort of men [3.4% (95% CI 2.4%-5.0%)], as compared to the average probability of diabetes (reference) of 1.8% for men overall. Neither analytical strategy revealed any strong relation between famine exposure and diabetes risk in women., Conclusion: Among the pre-defined Chinese famine period of 1959-1962, early-life exposure to famine was associated with increased diabetes risk in men but not in women, and these relations were independent of age., (© 2022.

Biomineralization as an alternative to traditional remediation measures has been widely applied to remediate copper (Cu)-contaminated sites due to its environmental-friendly nature. Immobilizing Cu is, however, a challenging task as it inevitably causes inactivation of ureolytic bacteria. In the present work, a series of test tube experiments were conducted to derive the relationships of Cu immobilization efficiency versus pH conditions. The Cu speciation transformation that is invisible in the test tube experiments was investigated via numerical simulations. Apart from that, the one-dimensional soil column tests, accompanied by the X-ray diffraction (XRD) and Raman spectroscopy analysis, mainly aimed not only to investigate the variations of Cu immobilization efficiency with the depth but to reveal the underlying mechanisms affecting the Cu immobilization efficiency. The results of the test tube experiments highlight the necessity of narrowing pH ranges to as close as 7 by introducing an appropriate bacterial inoculation proportion. The coordination adsorption of Cu, while performing the one-dimensional soil column tests, is encouraged by alkaline environments, which differs from the test tube experiments where Cu 2+ is capsulized by carbonate precipitates to prevent their migration. The findings highlight the potential of applying the microbial-induced carbonate precipitation (MICP) technology to Cu-rich water bodies and Cu-contaminated sites remediation., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier B.V.

Enzyme-induced carbonate precipitation (EICP) is considered as an environmentally friendly method for immobilizing heavy metals (HMs). The fundamental of the EICP method is to catalyze urea hydrolysis using the urease, discharging CO 3 2- and NH 4 + . CO 3 2- helps to form carbonates that immobilize HMs afterwards. However, HMs can depress urease activity and reduce the degree of urea hydrolysis. Herein, the potential of applying the chitosan-assisted EICP method to Pb and Cu immobilization was explored. The chitosan addition elevated the degree of urea hydrolysis when subjected to the effect of Cu 2+ toxicity where the protective effect, flocculation and adsorption, and the formation of precipitation, play parts in improving the Cu immobilization efficiency. The use of chitosan addition, however, also causes the side effect (copper-ammonia complex formation). Two calcium source additions, CaCl 2 and Ca(CH 3 COO) 2 , intervened in the test tube experiments not only to prevent pH from raising to values where Cu 2+ complexes with NH 3 but also to separate the urease enzyme and Cu 2+ from each other with the repulsion of charges. The FTIR spectra indicate that the chitosan addition adsorbs Cu 2+ through its surface hydroxyl and carboxyl groups, while the SEM images distinguish who the mineral are nucleating with. The findings shed light on the potential of applying the chitosan-assisted EICP method to remedy lead- and copper-rich water bodies., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier Ltd.

Piperlongumine (PL) can selectively inhibit the proliferation of various cancer cells by increasing reactive oxygen species (ROS) level to cause a redox imbalance in cancer cells rather than in normal cells. However, the clinical application of PL is limited by its poor cellular uptake. Natural borneol (NB) is extracted from the fresh branches and leaves of Cinnamomum camphora (L.) Presl. with the purity of (+)-borneol no less than 96.0%. NB has been often used as an adjuvant agent to promote the cellular uptake of other drugs. This study aims to investigate the effect of NB on the cellular uptake of PL for improving its antiglioma efficacy and underlying mechanism. NB obviously promoted the cellular uptake of PL with a 1.3-fold increase in the maximum peak concentration and an earlier peak time of 30 min in C6 glioma cells. The cellular uptake of PL was enhanced by NB through down-regulating the expression levels of P-glycoprotein (ABCB1) and breast cancer resistance protein (ABCG2). The combination of NB and PL significantly induced higher levels of ROS, which increased apoptosis and enhanced G2/M cycle arrest of C6 glioma cells, compared to PL alone administration. NB-enhanced antiglioma efficacy of PL without side effects was confirmed in tumor-bearing mice, which was attributed to the improved cellular uptake of PL. The distribution of PL in the tumor tissue of combined group increased 2.39 times than that of PL-treated group. We firstly report NB as an adjuvant agent to improve the antiglioma efficacy of PL in a ROS-dependent manner, which is due to the enhanced cellular uptake of PL by NB though down-regulating the expression levels of ABCB1 and ABCG2. This work provides a new strategy to promote the cellular uptake of PL with great potential for the treatment of glioma., Competing Interests: Declaration of Competing Interests The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022.

Background: Perforator-based free perforator flaps have become an important tool for the reconstruction of tissue defects. The effect of the number of perforators on the outcomes of perforator flaps has been widely debated. This study aimed to compare the outcomes of single- and multiple-perforator-based free perforator flaps in free-flap reconstruction., Methods: We searched PubMed, Web of Science, EMBASE, Chinese BioMedical Literature Database (CBM), Cochrane Library, and clinicaltrials.gov between January 2000 and June 2021 to identify studies that reported data on the outcomes of free perforator flaps. Two authors individually extracted data and performed quality assessment. Outcomes, including partial flap loss, total loss, fat necrosis, arterial insufficiency, venous insufficiency, hemorrhage and hematoma, wound dehiscence at recipient sites and donor site complications, were evaluated., Results: Thirty-two studies with 2498 flaps were included in our analysis. No significant difference was found in the rates of partial loss and arterial insufficiency of flaps, hemorrhage and hematoma, wound dehiscence at recipient sites and donor site complications. However, the multiple-perforator group showed significantly lower rates of total loss (relative risk [RR] = 1.08, 95% confidence interval [CI]: 0.78-1.79, p = .754), fat necrosis (RR = 1.79, 95% [CI]: 1.36-2.36, p = .000) and venous insufficiency (RR = 1.72, 95% CI: 1.07-2.79, p = .026) than the single-perforator group., Conclusion: The rates of total loss, fat necrosis and venous insufficiency in the multiple-perforator group were lower than those in the single-perforator group. Hence, we recommend that multiple perforators be included in the free perforator flap when appropriate, to yield better clinical outcomes in reconstruction., (© 2022 Wiley Periodicals LLC.)

Sexual dimorphism has commonly been found in many species. The phenotypes of Salix matsudana females and males are different under salinity stress. An F 1 population was selected to compare the differences between males and females. As a result, males showed stronger roots and heavier dry weights than females. The unique molecular mechanisms of males and females under salinity stress were further analyzed based on the root transcriptome of males and females. Both males and females up-regulated systemic acquired resistance genes, such as ADH and oxygenase-related genes, to resist salt. Moreover, many other abiotic stress response genes were up-regulated in males to adjust to salinity stress, while females showed more down-regulation of nitrogen metabolism-related genes to decrease the harm from salinity stress. The research on salinity tolerance in Salix matsudana males and females would help to further understand sexual dimorphism under selection pressure and provide benefits to the ecological environment., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Liu, Wang, Lian, Ma, Xiang, Wu, Luo, Ma, Chen, Yu, Zhong, Wei and Zhang.)
