Objectives: To investigate the safety and efficacy of prostatic artery embolization (PAE) in the treatment of lower urinary tract symptoms (LUTS) caused by benign prostatic hyperplasia (BPH), and to investigate predictors of clinical success of PAE., Methods: A retrospective analysis was used to collect 107 patients [median age 81.0 (73.0,85.0)] with BPH-related LUTS treated with PAE from September 2014 to February 2022 in a hospital. Repeated measurement ANOVA was used to compare the efficacy evaluation indicators at different times before and after PAE. Univariate and multivariate analyses were used to identify potential predictors of PAE clinical success and establish the optimal joint prediction model. The Receiver Operating Characteristic curves of the quantitative predictors and multivariate model prediction probability values significantly correlated with clinical success were plotted., Results: Of the 107 cases, 103 (96.3%) successfully underwent PAE. The International Prostate Symptom Score (IPSS) decreased from a baseline mean of 24.94 to 10.19 (P < 0.05) 3 months after PAE, and the mean IPSS at 6 months, 12 months and 24 months was 10.12, 11.30 and 11.86, respectively, which were statistically significant compared with baseline (P<0.05). Predictors of clinical success were greater prostate volume (> 65 ml, P = 0.018), adenomatous-dominant benign prostatic hyperplasia (AdBPH)(P = 0.030), indwelling catheterization due to urine retention (P = 0.028), and bilateral embolization (P = 0.018)., Conclusion: PAE was able to significantly improve BPH-related LUTS and the outcome indicators remained stable at long-term follow-up. Preoperative urinary retention catheters, AdBPH, larger prostate volume (> 65 ml) and bilateral embolization suggest better clinical efficacy., (© 2024.

Introduction: Uninsured patients have limited options to pay for necessary medical services. Most United States hospitals offer financial assistance programs (FAPs) to help patients pay for care, but the challenges of accessing these programs demonstrate a need for more solutions., Methods: This study was a retrospective review of 200 randomly sampled HAVEN Free Clinic patients from September 2022 to September 2023. Patients were eligible to be seen at HAVEN if 18-65 years old, without health insurance, and living in New Haven County, Connecticut. Application histories to Medicaid and hospital FAP at a non-profit tertiary care center in Connecticut were assessed., Results: In the 200-patient sample, average age was 43.4 ± 11.2 years old, 61.0% were female, and 86.5% were Hispanic or Latino. 68% were employed with a median household yearly income of $18,200 [$7,293-$26,741]. 80% had applied for a hospital FAP-71.1% were currently approved for Free Care or Discounted Care. 6% were approved for Medicaid; 2.5% were approved for Emergency Medicaid. Of those who applied for a hospital FAP, 28.3% received ≥ 1 application denial. Most common hospital FAP denial reasons were missing, wrong, or outdated proof of income (93.9%), and incomplete application (6.1%)., Conclusion: Hospital FAPs and Medicaid provide important access to care for uninsured patients, but are not without barriers and should not be viewed as the only solution. Improving hospital FAP access involves assessing eligibility at presentation, extending approval duration, and advocating for more funding. Addressing these barriers can advance equitable care for all., (© 2024. The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.)

Functionalized mesoporous materials have become a promising carrier for enzyme immobilization. In this study, Santa Barbara Amorphous 15 (SBA-15) was modified by N-aminoethyl-γ-aminopropyl trimethoxy (R). R-SBA-15 was employed to purify and immobilize recombinant β-glucosidase from Terrabacter ginsenosidimutans (BgpA) in one step for the first time. Optimum pH of the constructed R-SBA-15@BgpA were 7.0, and it has 20 ℃ higher optimal temperature than free enzyme. Relative activity of R-SBA-15@BgpA still retained > 70% at 42 ℃ after 8-h incubation. The investigation on organic reagent resistance revealed that the immobilized enzyme can maintain strong stability in 15% DMSO. In leaching test and evaluation of storage stability, only trace amount of protein was detected in buffer of the immobilized enzyme after storage at 4 ℃ for 33 days, and the immobilized BgpA still maintained > 50% relative activity. It also demonstrated good reusability, with 76.1% relative activity remaining after fourteen successive enzymatic hydrolyses of epimedin A to sagittatoside A. The newly proposed strategy is an effective approach for the purification and immobilization of BgpA concurrently. In addition, R-SBA-15@BgpA was demonstrated to have high efficiency and stability in this application, suggesting its great feasibility and potential to produce bioactive compounds such as secondary glycosides or aglycones from natural products., (© 2024.

The mangrove ecosystem is the world's fourth most productive ecosystem in terms of service value and offering rich biological resources. Microorganisms play vital roles in these ecological processes, thus researching the mangroves-microbiota is crucial for a deeper comprehension of mangroves dynamics. Amplicon sequencing that targeted V4 region of 16S rRNA gene was employed to profile the microbial diversities and community compositions of 19 soil samples, which were collected from the rhizosphere of 3 plant species (i.e., Avicennia marina, Ceriops tagal, and Rhizophora mucronata) in the mangrove forests of Lasbela coast, Pakistan. A total of 67 bacterial phyla were observed from three mangroves species, and these taxa were classified into 188 classes, 453 orders, 759 families, and 1327 genera. We found that Proteobacteria (34.9-38.4%) and Desulfobacteria (7.6-10.0%) were the dominant phyla followed by Chloroflexi (6.6-7.3%), Gemmatimonadota (5.4-6.8%), Bacteroidota (4.3-5.5%), Planctomycetota (4.4-4.9%) and Acidobacteriota (2.7-3.4%), Actinobacteriota (2.5-3.3%), and Crenarchaeota (2.5-3.3%). After considering the distribution of taxonomic groups, we prescribe that the distinctions in bacterial community composition and diversity are ascribed to the changes in physicochemical attributes of the soil samples (i.e., electrical conductivity (EC e ), pH, total organic matter (OM), total organic carbon (OC), available phosphorus (P), and extractable potassium (CaCO 3 ). The findings of this study indicated a high-level species diversity in Pakistani mangroves. The outcomes may also aid in the development of effective conservation policies for mangrove ecosystems, which have been hotspots for anthropogenic impacts in Pakistan. To our knowledge, this is the first microbial research from a Pakistani mangrove forest., (© 2023. Institute of Microbiology, Academy of Sciences of the Czech Republic, v.v.i.)

The suppressor of cytokine signaling 2 (SOCS2) has been identified to act as a tumor suppressor in breast cancer (BC) progression. However, the action of SOCS2 in macrophage polarization in BC cells has not been reported yet. The qRT-PCR and western blotting were adopted for detecting the levels of mRNAs and proteins. The macrophage M2 polarization was analyzed by flow cytometry. Analyses of cell oncogenic phenotypes and tumor growth were conducted using 5-ethynyl-2'-deoxyuridine (EdU), flow cytometry, scratch, Transwell, tube formation assays in vitro, and tumor xenograft assay in vivo, respectively. The interaction between CEBPA (CCAAT Enhancer Binding Protein Alpha) and SOCS2 was confirmed using bioinformatics analysis and dual-luciferase reporter assay. SOCS2 was lowly expressed in BC tissues and cells. Functionally, overexpression of SOCS2 inhibited macrophage M2 polarization, and impaired BC cell proliferation, angiogenesis, and metastasis. Mechanistically, CEBPA bound to the promoter region of SOCS2, and promoted its transcription. A low CEBPA expression was observed in BC tissues and cells. Forced expression of CEBPA also suppressed macrophage M2 polarization, BC cell proliferation, angiogenesis, and metastasis. Moreover, the anticancer effects mediated by CEBPA were abolished by SOCS2 knockdown. In addition, CEBPA overexpression impeded BC growth in nude mice by regulating SOCS2. CEBPA suppressed macrophage M2 polarization, BC cell proliferation, angiogenesis, and metastasis by promoting SOCS2 transcription in a targeted manner., (© 2024.

Background: Textbook outcome (TO) has been widely employed as a comprehensive indicator to assess the short-term prognosis of patients with cancer. Preoperative malnutrition is a potential risk factor for adverse surgical outcomes in patients with gastric cancer (GC). This study aimed to compare the TO between robotic-assisted gastrectomy (RAG) and laparoscopic-assisted gastrectomy (LAG) in malnourished patients with GC., Methods: According to the diagnostic consensus of malnutrition proposed by Global Leadership Initiative on Malnutrition (GLIM) and Nutrition Risk Index (NRI), 895 malnourished patients with GC who underwent RAG (n = 115) or LAG (n = 780) at a tertiary referral hospital between January 2016 and May 2021 were included in the propensity score matching (PSM, 1:2) analysis., Results: After PSM, no significant differences in clinicopathological characteristics were observed between the RAG (n = 97) and LAG (n = 194) groups. The RAG group had significantly higher operative time and lymph nodes harvested, as well as significantly lower blood loss and hospital stay time compared to the LAG group. More patients in the RAG achieved TO. Logistic regression analysis revealed that RAG was an independent protective factor for achieving TO. There were more adjuvant chemotherapy (AC) cycles in the RAG group than in the LAG group. After one year of surgery, a higher percentage of patients (36.7% vs. 22.8%; P < 0.05) in the RAG group recovered from malnutrition compared to the LAG group., Conclusions: For malnourished patients with GC, RAG performed by experienced surgeons can achieved a higher rate of TO than those of LAG, which directly contributed to better AC compliance and a faster restoration of nutritional status., (© 2024.

Phthalate acid esters (PAEs) and their metabolites, such as di-n-butyl phthalate (DBP) and mono-n-butyl phthalate (MBP), are known to cause male reproductive damage. Lactiplantibacillus plantarum RS20D has demonstrated the ability to remove both DBP and MBP in vitro, suggesting its potential as a detoxifying agent against these compounds. This study aimed to investigate the protective effects of RS20D on DBP or MBP-induced male reproductive toxicity in adolescent rats. Oral administration of RS20D significantly mitigated the histological damage to the testes caused by MBP or DBP, restored sperm concentration, morphological abnormalities, and the proliferation index in MBP-exposed rats, and partially reversed spermatogenic damage in DBP-exposed rats. Furthermore, RS20D restored serum levels of estradiol (E2) and testosterone, and superoxide dismutase (SOD) activity in DBP-exposed rats, significantly increased testosterone levels in MBP-exposed rats, and restored copper (Cu) concentrations in the testes after exposure to DBP or MBP. Additionally, RS20D effectively modulated the intestinal microbiota in DBP-exposed rats and partially ameliorated dysbiosis induced by MBP, which may be associated with the alleviation of reproductive toxic effects induced by DBP or MBP. In conclusion, this study demonstrates that RS20D administration can alleviate male reproductive toxicity and gut dysbacteriosis induced by DBP or MBP exposure, providing a dietary strategy for the bioremediation of PAEs and their metabolites., (© 2024.

Stress-induced intestinal epithelial injury (IEI) and a delay in repair in infancy are predisposing factors for refractory gut diseases in adulthood, such as irritable bowel syndrome (IBS). Hence, it is necessary to develop appropriate mitigation methods for mammals when experiencing early-life stress (ELS). Weaning, as we all know, is a vital procedure that all mammalian newborns, including humans, must go through. Maternal separation (MS) stress in infancy (regarded as weaning stress in animal science) is a commonly used ELS paradigm. Drinking silicon-rich alkaline mineral water (AMW) has a therapeutic effect on enteric disease, but the specific mechanisms involved have not been reported. Herein, we discover the molecular mechanism by which silicon-rich AMW repairs ELS-induced IEI by maintaining intestinal stem cell (ISC) proliferation and differentiation through the glucagon-like peptide (GLP)2-Wnt1 axis. Mechanistic study showed that silicon-rich AMW activates GLP2-dependent Wnt1/β-catenin pathway, and drives ISC proliferation and differentiation by stimulating Lgr5 + ISC cell cycle passage through the G1-S-phase checkpoint, thereby maintaining intestinal epithelial regeneration and IEI repair. Using GLP2 antagonists (GLP2 3-33 ) and small interfering RNA (SiWnt1) in vitro, we found that the GLP2-Wnt1 axis is the target of silicon-rich AMW to promote intestinal epithelium regeneration. Therefore, silicon-rich AMW maintains intestinal epithelium regeneration through the GLP2-Wnt1 axis in piglets under ELS. Our research contributes to understanding the mechanism of silicon-rich AMW promoting gut epithelial regeneration and provides a new strategy for the alleviation of ELS-induced IEI., (© 2024.

As an inevitable part of construction and demolition (C&D) waste, muck has a dreadful environmental impact due its inadequate management by the traditional governance process. This paper therefore focuses on the management of muck generated from C&D waste by utilizing platform governance as an alternative process, which should more effectively contribute to China's circular economy. The study explores the feasibility of providing such a platform governance mode by using Petri net to compare the traditional governance process and platform governance process for the management of muck trucks, and by using Nanjing's muck smart supervision platform as a case study to assess the effectiveness of the platform governance mode. Results from Petri net simulation modeling reveal that the platform governance mode is more effective than the traditional mode, and from the case study it is found that the success of Nanjing's muck waste management can be attributed to the platform governance mode. The platform management approach can therefore contribute to the sustainability of muck waste governance, and is suitable as an integrated and effective management mode for current practices of muck waste management and resource recovery in China. The main finding from the study is that the platform governance mode significantly improves the efficiency of muck waste management as compared with the traditional governance mode and can therefore provide greater economic and environmental benefits as part of a circular economy., (© 2023.

Objective: This study aimed to evaluate the clinical application and efficacy of a super-low-positioned intestinal decompression tube in the treatment of intestinal obstruction., Methods: A total of 130 patients with postoperative small bowel obstruction were included in this study. The patients were divided into a super-low-positioned intestinal decompression group and a conventional intestinal decompression group. The clinical data, treatment outcomes, and complications were compared between the two groups., Results: The technical success rate of placing the super-low-positioned intestinal decompression tube was 100%, with no intraoperative complications. The patients in the super-low-positioned intestinal decompression group had a significantly shorter hospital stay (8.3 ± 5.2 vs 17.7 ± 13.3, P < 0.001) and a higher non-operative treatment success rate (83.6% vs 57.9%, P = 0.001) compared to the conventional intestinal decompression group. Multivariate logistic regression analysis showed that the placement of a super-low-positioned intestinal decompression tube was an independent protective factor for treatment outcomes (P = 0.001). The hospital stay was significantly shorter in the super-low-positioned intestinal decompression group compared to the conventional group in both successful non-operative treatment patients (6.9 ± 3.0 vs 11.2 ± 7.5, P < 0.001) and failed non-operative treatment patients (16.2 ± 7.4 vs 26.6 ± 14.4, P < 0.001). The super-low-positioned intestinal decompression tube effectively relieved the "Self-strangulation" phenomenon in patients with intestinal obstruction., Conclusion: The super-low-positioned intestinal decompression tube is a safe and effective method for the treatment of intestinal obstruction, with better treatment outcomes and shorter hospital stays compared to conventional intestinal decompression. Further prospective studies are needed to validate these findings., (© 2023. The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.)

Constructing the efficacious and applicable bi-functional electrocatalysts and establishing out the mechanisms of organic electro-oxidation by replacing anodic oxygen evolution reaction (OER) are critical to the development of electrochemically-driven technologies for efficient hydrogen production and avoid CO 2 emission. Herein, the hetero-nanocrystals between monodispersed Pt (~ 2 nm) and Ni 3 S 2 (~ 9.6 nm) are constructed as active electrocatalysts through interfacial electronic modulation, which exhibit superior bi-functional activities for methanol selective oxidation and H 2 generation. The experimental and theoretical studies reveal that the asymmetrical charge distribution at Pt-Ni 3 S 2 could be modulated by the electronic interaction at the interface of dual-monodispersed heterojunctions, which thus promote the adsorption/desorption of the chemical intermediates at the interface. As a result, the selective conversion from CH 3 OH to formate is accomplished at very low potentials (1.45 V) to attain 100 mA cm -2 with high electronic utilization rate (~ 98%) and without CO 2 emission. Meanwhile, the Pt-Ni 3 S 2 can simultaneously exhibit a broad potential window with outstanding stability and large current densities for hydrogen evolution reaction (HER) at the cathode. Further, the excellent bi-functional performance is also indicated in the coupled methanol oxidation reaction (MOR)//HER reactor by only requiring a cell voltage of 1.60 V to achieve a current density of 50 mA cm -2 with good reusability., (© 2024.

Background: Neuronal intranuclear inclusion disease (NIID) is a rare highly heterogeneous disease. In this paper, we present a case of NIID featured in cortical involvement in left hemisphere of brain and the imaging changes in the process of the disease., Case Presentation: A 57-year-old female was hospitalized due to recurrent attacks of headache with cognitive impairment and tremor for 2 years. The symptoms of headache episodes were reversible. The characteristic radiologic change was high intensity signal involving the grey matter-white matter junction on the brain diffusion-weighted imaging (DWI), which existed in the frontal lobe and then extended backwards. Atypical features on fluid-attenuated inversion recovery (FLAIR) sequences showing small patchy high signals in the cerebellar vermis. High signals and edema were detected on FLAIR images along the cortex of the left occipito-parieto-temporal lobes, expanding and gradually shrinking in the follow-up visit. Besides, cerebral atrophy and bilateral symmetrical leukoencephalopathy were also detected. Skin biopsy and genetic testing confirmed the diagnosis of NIID., Conclusion: Except for typical radiological change strongly suggesting NIID, it is also necessary to notice the insidious symptoms of NIID combining with some atypical imaging features to make an early diagnosis. Skin biopsies or genetic testing should be carried out early in patients with highly suspected NIID., (© 2023.

Key Message: Functional loss of Arabidopsis Sar1b with that of either Sar1a or Sar1c inhibits mitosis of functional megaspores, leading to defective embryo sac formation and reduced fertility. Vesicular trafficking among diverse endomembrane compartments is critical for eukaryotic cells. Anterograde trafficking from endoplasmic reticulum (ER) to the Golgi apparatus is mediated by coat protein complex II (COPII) vesicles. Among five cytosolic components of COPII, secretion-associated Ras-related GTPase 1 (Sar1) mediates the assembly and disassembly of the COPII coat. Five genes in Arabidopsis encode Sar1 isoforms, whose different cargo specificities and redundancy were both reported. We show here that Arabidopsis Sar1a, Sar1b, and Sar1c mediate the development of female gametophytes (FGs), in which Sar1b plays a major role, whereas Sar1a and Sar1c play a minor role. We determined that female transmission of sar1a;sar1b or sar1c;sar1b was significantly reduced due to defective mitosis of functional megaspores. Half of ovules in sar1a;sar1b/+ or sar1c;sar1b/+ plants failed to attract pollen tubes, leading to fertilization failure. The homozygous sar1a;sar1b or sar1c;sar1b double mutant was obtained by introducing either UBQ10:GFP-Sar1b or UBQ10:GFP-Sar1c, supporting their redundant function in FG development., (© 2023.

Context: The article presents a comparative study of the electronic, magnetic and catalytic properties of CrPS 4 , AlPS 4 , GaPS 4 and their expanded structures. It is finally found that: When n = 2, 3, the internal electron mobility of the configurations is stronger than when n = 0,1. When n = 1, the five configurations, except configuration 1Cr (4) , are susceptible to both electrophilic and nucleophilic reactions at the same time. The configurations are more prone to nucleophilic reactions when n = 2 and 3, and the reaction sites are mainly located on the metal atoms; the more metal atoms, the more nucleophilic reaction sites. When the M atoms in the configuration are Al and Ga atoms, there is no big difference between the contribution of metal atoms and non-metal atoms to the magnetism in the configuration, while in the configuration containing Cr atoms, the metal atoms contribute more to the magnetism and mainly originate from the d-orbitals, which has better magnetic properties and greater application value. Configuration 2Cr (4) and configuration 1Cr (2) have better catalytic and adsorption activities and are most suitable as catalysts., Methods: In the article, based on topological principles, density functional theory, B3LYP functional and def2-tzvp basis group and Gaussian16 quantum chemistry software were used to optimise the calculations of the clusters CrPS 4 , AlPS 4 , GaPS 4 and their expanded configurations, with the most stable structure selected for each cluster, and finally, with the help of Multiwfn program, the required analytical data were obtained by assisting the calculations., (© 2023.

Purpose: To evaluate the feasibility of using mpMRI image features predicted by AI algorithms in the prediction of clinically significant prostate cancer (csPCa)., Materials and Methods: This study analyzed patients who underwent prostate mpMRI and radical prostatectomy (RP) at the Affiliated Hospital of Jiaxing University between November 2017 and December 2022. The clinical data collected included age, serum prostate-specific antigen (PSA), and biopsy pathology. The reference standard was the prostatectomy pathology, and a Gleason Score (GS) of 3 + 3 = 6 was considered non-clinically significant prostate cancer (non-csPCa), while a GS ≥ 3 + 4 was considered csPCa. A pre-trained AI algorithm was used to extract the lesion on mpMRI, and the image features of the lesion and the prostate gland were analyzed. Two logistic regression models were developed to predict csPCa: an MR model and a combined model. The MR model used age, PSA, PSA density (PSAD), and the AI-predicted MR image features as predictor variables. The combined model used biopsy pathology and the aforementioned variables as predictor variables. The model's effectiveness was evaluated by comparing it to biopsy pathology using the area under the curve (AUC) of receiver operation characteristic (ROC) analysis., Results: A total of 315 eligible patients were enrolled with an average age of 70.8 ± 5.9. Based on RP pathology, 18 had non-csPCa, and 297 had csPCa. PSA, PSAD, biopsy pathology, and ADC value of the prostate outside the lesion (ADC prostate ) varied significantly across different ISUP grade groups of RP pathology (P < 0.001). Other clinical variables and image features did not vary significantly across different ISUP grade groups (P > 0.05). The MR model included PSAD, the ratio of ADC value between the lesion and the prostate outside the lesion (ADC lesion/prostate ), the signal intensity ratio of DWI between the lesion and the prostate outside the lesion (DWI lesion/prostate ), and the ratio of DWI lesion/prostate to ADC lesion/prostate . The combined model included biopsy pathology, ADC lesion/prostate , mean signal intensity of the lesion on DWI (DWI lesion ), DWI signal intensity of the prostate outside the lesion (DWI prostate ), and signal intensity ratio of DWI between the lesion and the prostate outside the lesion (DWI lesion/prostate ). The AUC of the MR model (0.830, 95% CI 0.743, 0.916) was not significantly different from that of biopsy pathology (0.820, 95% CI 0.728, 0.912, P = 0.884). The AUC of the combined model (0.915, 95% CI 0.849, 0.980) was higher than that of the biopsy pathology (P = 0.042) and MR model (P = 0.031)., Conclusion: The aggressiveness of prostate cancer can be effectively predicted using AI-extracted image features from mpMRI images, similar to biopsy pathology. The prediction accuracy was improved by combining the AI-extracted mpMRI image features with biopsy pathology, surpassing the performance of biopsy pathology alone., (© 2023. The Author(s).)

The heat shock response (HSR) is a cellular protective mechanism that is characterized by the induction of heat shock transcription factors (HSFs) and heat shock proteins (HSPs) in response to diverse cellular and environmental stressors, including cadmium (Cd). However, little is known about the relationship between the damaging effects of Cd and the HSR pathway in the chicken cerebrum following Cd exposure. To explore whether Cd exposure elicits cerebral damage and triggers the HSR pathway, chicks were exposed to Cd in the daily diet at different concentrations (35, 70, or 140 mg/kg feed) for 90 days, while a control group was fed the standard diet without Cd. Histopathological examination of cerebral tissue from Cd-exposed chickens showed neuronal damage, as evidenced by swelling and degeneration of neurons, loss of neurons, and capillary damage. Cd exposure significantly increased mRNA expression of HSF1, HSF2, and HSF3, and mRNA and protein expression of three major stress-inducible HSPs (HSP60, HSP70, and HSP90). Moreover, Cd exposure differentially modulated mRNA expression of small HSP (sHSPs), most notably reducing expression of HSP27 (HSPB1). Furthermore, Cd exposure increased TUNEL-positive neuronal apoptotic cells and up-regulated protein expression of caspase-1, caspase-8, caspase-3, and p53, leading to apoptosis. Taken together, these data demonstrate that activation of the HSR and apoptotic pathways by Cd exposure is involved in Cd-elicited cerebral damage in the chicken. Synopsis for the graphical abstract Cadmium (Cd)-induced neuronal damage triggers the heat shock response (HSR) by activating heat shock transcription factors (HSFs) and subsequent induction of major heat shock proteins (notably, HSP60, HSP70, and HSP90). Moreover, Cd exposure activates caspase-1, caspase-8, caspase-3, and p53 protein, thereby resulting in neuronal apoptosis in the chicken brain., (© 2023.

Background: The methods for sentinel lymph node (SLN) biopsy in breast cancer have been variable in type and number of tracers. Some units have abandoned the use of blue dye (BD) due to adverse reactions. Fluorescence-guided biopsy with indocyanine green (ICG) is a relatively novel technique. This study compared the clinical efficacy and costs between novel dual tracer ICG and radioisotope (ICG-RI) with "gold standard" BD and radioisotope (BD-RI)., Methods: Single-surgeon study of 150 prospective patients with early breast cancer undergoing SLN biopsy (2021-2022) using ICG-RI compared with a retrospective cohort of 150 consecutive previous patients using BD-RI. Number of SLNs identified, rate of failed mapping, identification of metastatic SLNs, and adverse reactions were compared between techniques. Cost-minimisation analysis performed by using Medicare item numbers and micro-costing analysis., Results: Total number of SLNs identified with ICG-RI and BD-RI was 351 and 315, respectively. Mean number of SLNs identified with ICG-RI and BD-RI was 2.3 (standard deviation [SD] 1.4) and 2.1 (SD 1.1), respectively (p = 0.156). There were no cases of failed mapping with either dual technique. Metastatic SLNs were identified in 38 (25.3%) ICG-RI patients compared with 30 (20%) BD-RI patients (p = 0.641). There were no adverse reactions to ICG, whereas four cases of skin tattooing and anaphylaxis were associated with BD (p = 0.131). ICG-RI cost an additional AU$197.38 per case in addition to the initial cost for the imaging system., Clinical Trial Registration:  ACTRN12621001033831., Conclusions: Novel tracer combination, ICG-RI, provided an effective and safe alternative to "gold standard" dual tracer. The caveat was the significantly greater costs associated with ICG., (© 2023. The Author(s).)

A Gram-staining negative, aerobic, motile, and short rods strain, designated SYSU M60028 T , was isolated from a Pearl River sediment sample in Guangzhou, Guangdong, China. The isolate could be able to grow at pH 6.0-8.0 (optimum, pH 7.0), 25-37 °C (optimum, 28 °C) and in the presence of 0-2% (w/v) NaCl (optimum, 0% NaCl). The cellular polar lipids of this strain were phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, one unidentified aminolipid and three unidentified lipids. The respiratory quinone of SYSU M60028 T was found to be Q-10. The major fatty acids (> 5% of total) were summed feature 8, C 16:0 , and C 18:1 ω7c 11-methy1. The genomic DNA G + C content was 69.9%. Phylogenetic analyses based on 16S rRNA gene sequences and core genes indicated that strain SYSU M60028 T belonged to the genus Alsobacter and had the highest sequences similarities to Alsobacter metallidurans SK200a-9 T (96.87%) and Alsobacter soli SH9 T (96.87%). Based on the phenotypic, genotypic, and phylogenetic data, strain SYSU M0028 T should be considered to represent a novel species of the genus Alsobacter, for which the name Alsobacter ponti sp. nov. is proposed. The type strain is SYSU M60028 T (= CGMCC 1.19341 T  = KCTC 92046 T )., (© 2023. The Author(s), under exclusive licence to Springer Nature Switzerland AG.)

Management of tailings at metal mine smelter sites can reduce the potential hazards associated with exposure to toxic metal(loid)s and residual organic flotation reagents. In addition, microbes in the tailings harboring multi-resistance genes (e.g., tolerance to multiple antimicrobial agents) can cause high rates of morbidity and global economic problems. The potential co-selection mechanisms of antibiotic resistance genes (ARGs) and metal(loid) resistance genes (MRGs) during tailings sulfate-reducing bacteria (SRB) treatment have been poorly investigated. Samples were collected from a nonferrous metal mine tailing site treated with an established SRB protocol and were analyzed for selected geochemical properties and high throughput sequencing of 16S rRNA gene barcoding. Based on the shotgun metagenomic analysis, the bacterial domain was dominant in nonferrous metal(loid)-rich tailings treated with SRB for 12 months. KEGGs related to ARGs and MRGs were detected. Thiobacillus and Sphingomonas were the main genera carrying the bacA and mexEF resistance operons, along with Sulfuricella which were also found as the main genera carrying MRGs. The SRB treatment may mediate the distribution of numerous resistance genes. KOs based on the metagenomic database indicated that ARGs (mexNW, merD, sul, and bla) and MRGs (czcABCR and copRS genes) were found on the same contig. The SRB strains (Desulfosporosinus and Desulfotomaculum), and the acidophilic strain Acidiphilium significantly contributed to the distribution of sul genes. The functional metabolic pathways related to siderophores metabolism were largely from anaerobic genera of Streptomyces and Microbacterium. The presence of arsenate reductase, metal efflux pump, and Fe transport genes indicated that SRB treatment plays a key role in the metal(loid)s transformation. Overall, our findings show that bio-treatment is an effective tool for managing ARGs/MRGs and metals in tailings that contain numerous metal(loid) contaminants., (© 2023.

CCN/WISP (cellular communication network factors, or Wnt-inducted secreted proteins) family of proteins consists of six extracellular matrix (ECM)-associated proteins that regulate development, cell adhesion and proliferation, ECM remodeling, inflammation, and tumorigenesis. In the last two decades, metabolic regulation by these matricellular proteins has been studied extensively, several excellent reviews have covered the roles of CCN1, -2 and - 5. In this brief review, we will focus on those lesser-known members and more recent discoveries, together with other recent articles presenting a more complete picture of the current state of knowledge. We have found that CCN2, -4, and - 5 promote pancreatic islet function, while CCN3 plays a unique and negative role. CCN3 and - 4 are pro-adiposity leading to insulin resistance, but CCN5 and - 6 are anti-adiposity. While CCN2 and - 4 promote tissue fibrosis and inflammation, all other four members are clearly anti-fibrotic. As for cellular signaling, they are known to interact with integrins, other cell membrane proteins and ECM thereby regulate Akt/protein kinase B, myocardin-related transcription factor (MRTF), and focal adhesion kinase. Yet, a cohesive mechanism of action to comprehensively explain those major functions is still lacking., (© 2023. The International CCN Society.)

To compare the short-term outcomes of a new gastrointestinal decompression tube combined with conservative treatment in patients with esophagojejunal anastomotic leakage (EJAL) after total gastrectomy. We retrospectively analyzed the data of 81 patients with EJAL who had undergone total gastrectomy and Roux-en-Y reconstruction at Fujian Medical University Union Hospital between January 2014 and December 2021. The patients were divided into experimental (12 patients with new gastrointestinal decompression tube plus conservative treatment) and control (69 patients with conservative treatment) groups, according to the different treatment methods they received. Anatomic defect size linearly correlated with time to clinical success, hospital stay, and hospital cost in the control group. The two groups showed no significant differences in anastomotic defect size, time of defect after surgery, hospitalization cost, and time of antibiotic use. However, the time to clinical success was significantly shorter in the experimental group than in the control group (16.0 ± 8.3 vs. 23.6 ± 17.8, P = 0.04), as was the length of hospital stay (30.1 ± 6.3 vs. 36.8 ± 16.7, P = 0.017). Furthermore, when the defect size was ≥ 4 mm, the time to clinical success, hospital stay, and hospital cost in the experimental group were lower than those in the control group (P < 0.05). Placement of a new gastrointestinal decompression tube is a safe treatment. When the defect size is ≥ 4 mm, the time to clinical success, length of hospital stay, and hospital cost can be reduced., (© 2022.

Cadmium (Cd) is a food contaminant that poses serious threats to animal health, including birds. It is also an air pollutant with well-known neurotoxic effects on humans. However, knowledge on the neurotoxic effects of chronic Cd exposure on chicken is limited. Thus, this study assessed the neurotoxic effects of chronic Cd on chicken cerebellum. Chicks were exposed to 0 (control), 35 (low), and 70 (high) mg/kg of Cd for 90 days, and the expression of genes related to the heat-shock response was investigated. The chickens showed clinical symptoms of ataxia, and histopathology revealed that Cd exposure decreased the number of Purkinje cells and induced degeneration of Purkinje cells with pyknosis, and some dendrites were missing. Moreover, Cd exposure increased the expression of heat-shock factors, HSF1, HSF2, and HSF3, and heat-shock proteins, HSP60, HSP70, HSP90, and HSP110. These changes indicate that HSPs improve the tolerance of the cerebellum to Cd. Conversely, the expressions of HSP10, HSP25, and HSP40 were decreased significantly, which indicated that Cd inhibits the expression of small heat-shock proteins. However, HSP27 and HSP47 were upregulated following low-dose Cd exposure, but downregulated under high-dose Cd exposure. This work sheds light on the toxic effects of Cd on the cerebellum, and it may provide evidence for health risks posed by Cd. Additionally, this work also identified a novel target of Cd exposure in that Cd induces cerebellar injury by disrupting the heat-shock response. Cd can be absorbed into chicken's cerebellum through the food chain, which eventually caused cerebellar injury. This study provided a new insight that chronic Cd-induced neurotoxicity in the cerebellum is associated with alterations in heat-shock response-related genes, which indicated that Cd through disturbing heat-shock response induced cerebellar injury., (© 2022.

This study evaluates carbon emissions of construction and demolition (C&D) waste generated by building refurbishment, using a life cycle assessment approach through a case study project in China. Three waste management scenarios were developed for a building refurbishment project in the city of Suzhou. Scenario 1 is under the business-as-usual C&D waste management practice in China; scenario 2 is based on the open-ended 3R strategy, which focuses on the downstream impact of waste; and scenario 3 considers both the upstream and downstream impact of waste. The results reveal that the composition of the waste generated from building refurbishment projects is different from construction and demolition projects. In the life cycle of C&D waste management of building refurbishment projects, the refurbishment material stage generates the highest carbon emissions compared to the dismantlement, refurbishment construction, and refurbishment material end of life stages. Scenario 1 produces higher carbon emissions than scenario 2, but the difference is not significant in the whole life cycle of the building refurbishment project, whereas carbon emissions for scenario 3 are significantly less than both scenario 1 and scenario 2. The study finds the reason for this difference is that scenario 1 and scenario 2 are based on a linear economy that relies on unsustainable demand for raw materials, whereas scenario 3 is based on a circular economy that uses upcycled materials to substitute for raw materials and considers waste management from a cradle to cradle perspective. This study fills a research gap by evaluating carbon emissions of different waste management strategies for building refurbishment projects, which are expected to be an increasing portion of overall construction activity in China for the foreseeable future., (© 2021.

Driven by the massive demand in recent years, the production of β-alanine has significantly progressed in chemical and biological ways. Although the chemical method is relatively mature compared to biological synthesis, its high cost of waste disposal and environmental pollution does not meet the environmental protection standard. Hence, the biological method has become more prevalent as a potential alternative to the chemical synthesis of β-alanine in recent years. As a result, the aspartate pathway from L-aspartate to β-alanine (the most significant rate-limiting step in the β-alanine synthesis) catalyzed by L-aspartate-α-decarboxylase (ADC) has become a research hotspot in recent years. Therefore, it is vital to comprehensively understand the different enzymes that possess a similar catalytic ability to ADC. This review will investigate the exploratory process of unique synthesis features and catalytic properties of ADC/ADC-like enzymes in particular creatures with similar catalytic capacity or high sequence homology. At the same time, we will discuss the different β-alanine production methods which can apply to future industrialization., (© 2022. The Author(s), under exclusive licence to Springer Nature B.V.)

In recent years, the research of phenylethynylcopper (PhC 2 Cu) in photocatalysis has attracted immense attention. However, its synthesis requires two steps extending over 9 days. In this paper, the successful preparation of PhC 2 Cu nanowires is reported using a highly rapid and facile one-step method directly using copper acetate and phenylacetylene as raw materials and ascorbic acid as reducing agent. The kinetic studies indicated that the synthetic reaction follows a pseudo-second-order equation through electrical conductivity. Comparative studies of the crystal structures, morphologies, and optical properties of PhC 2 Cu prepared by the traditional two-step and the current one-step methods were conducted using XRD, SEM, UV-Vis Drs, FT-IR, Raman spectra, and photocurrent. Meanwhile, the PhC 2 Cu nanowires exhibited excellent photocatalytic activity to degrade methyl violet (MV) and glyphosate. This facile and rapid method dramatically improves the preparation efficiency of PhC 2 Cu, and the obtained PhC 2 Cu also shows higher photocatalytic activity. This remarkable progress enables the possibility of large-scale and efficient preparation of PhC 2 Cu with high photocatalytic activity, indicating their excellent application prospect in photocatalysis., (© 2022.

Background: Robotic surgery may be advantageous for complex surgery. We aimed to compare the intraoperative and postoperative short-term outcomes of spleen-preserving splenic hilar lymphadenectomy (SPSHL) during robotic and laparoscopic total gastrectomy., Methods: From July 2016 to December 2020, the clinicopathological data of 115 patients who underwent robotic total gastrectomy combined with robotic SPSHL (RSPSHL) and 697 patients who underwent laparoscopic total gastrectomy combined with laparoscopic SPSHL (LSPSHL) were retrospectively analyzed. A 1:2 ratio propensity score matching (PSM) was used to balance the differences between the two groups to compare their outcomes. The Generic Error Rating Tool was used to evaluate the technical performance., Results: After PSM, the baseline preoperative characteristics of the 115 patients in the RSPSHL and 230 patients in the LSPSHL groups were balanced. The dissection time of the region of the splenic artery trunk (5.4 ± 1.9 min vs. 7.8 ± 3.6 min, P < 0.001), the estimated blood loss during SPSHL (9.6 ± 4.8 ml vs. 14.9 ± 7.8 ml, P < 0.001), and the average number of intraoperative technical errors during SPSHL (15.1 ± 3.4 times/case vs. 20.7 ± 4.3 times/case, P < 0.001) were significantly lower in the RSPSHL group than in the LSPSHL group. The RSPSHL group showed higher dissection rates of No. 10 (78.3% vs. 70.0%, P = 0.104) and No. 11d (54.8% vs. 40.4%, P = 0.012) lymph nodes and significantly improved postoperative recovery results in terms of times to ambulation, first flatus, and first intake (P < 0.05). The splenectomy rates of the two groups were similar (1.7% vs. 0.4%, P = 0.539), and there was no significant difference in morbidity and mortality within postoperative 30 days (13.0% vs. 15.2%, P = 0.589)., Conclusion: Compared to LSPSHL, RSPSHL has more advantages in terms of surgical qualities and postoperative recovery process with similar morbidity and mortality. For complex SPSHL, robotic surgery may be a better choice., (© 2022. The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.)

Objective: There is insufficient evidence to evaluate the long-term outcomes of robotic radical gastrectomy. The aim of this study was to compare the radical results and long-term outcomes of robotic and laparoscopic radical gastrectomy., Methods: We prospectively collected and retrospectively analyzed the general clinicopathological data of gastric cancer patients treated with robotic radical gastrectomy (RG) and laparoscopic radical gastrectomy (LG) from July 2016 to July 2018 at Fujian Medical University Union Hospital. The RG cohort was matched 1:3 with the LG cohort by using propensity score matching (PSM). The primary endpoints of the study were 3-year overall survival (OS) and 3-year relapse-free survival (RFS)., Results: The study included 221 patients treated with RG and 1106 patients treated with LG for gastric cancer. After PSM, 211 patients were included in the RG cohort, and 663 patients were included in the LG cohort. The 3-year OS rate was 81.0% in the robotic cohort and 79.3% in the laparoscopic cohort (log-rank test, P = 0.516). The 3-year RFS rate was 78.7% in the robotic cohort and 75.6% in the laparoscopic cohort (log-rank test, P = 0.600). In the subgroup analyses, no significant differences were noted between the RG and LG cohorts in terms of 3-year OS and 3-year RFS (all P > 0.05). The therapeutic value index of each lymph node station dissection in the robotic cohort was comparable to that in the laparoscopic cohort., Conclusion: Robotic radical gastrectomy can achieve radical results and long-term outcomes comparable to laparoscopic surgery, and further multicenter prospective studies can be conducted to assess the clinical efficacy of robotic radical gastrectomy., (© 2022.

Electrocatalytic water splitting is a viable technique for generating hydrogen but is precluded from the sluggish kinetics of oxygen evolution reactions (OER). Small molecule oxidation reactions with lower working potentials, such as methanol oxidation reactions, are good alternatives to OER with faster kinetics. However, the typically employed Ni-based electrocatalysts have poor activity and stability. Herein, a novel three-dimensional (3D)-networking Mo-doped Ni(OH) 2 with ultralow Ni-Ni coordination is synthesized, which exhibits a high MOR activity of 100 mA cm -2 at 1.39 V, delivering 28 mV dec -1 for the Tafel slope. Meanwhile, hydrogen evolution with value-added formate co-generation is boosted with a current density of more than 500 mA cm -2 at a cell voltage of 2.00 V for 50 h, showing excellent stability in an industrial alkaline concentration (6 M KOH). Mechanistic studies based on density functional theory and X-ray absorption spectroscopy showed that the improved performance is mainly attributed to the ultralow Ni-Ni coordination, 3D-networking structures and Mo dopants, which improve the catalytic activity, increase the active site density and strengthen the Ni(OH) 2 3D-networking structures, respectively. This study paves a new way for designing electrocatalysts with enhanced activity and durability for industrial energy-saving hydrogen production., (© 2022. The Author(s).)

Cadmium (Cd) is a toxic environmental contaminant, which bio-accumulate in animals through the food chain. Cerebellum is one of the primary target organs for Cd exposure. In this study, we established a chronic Cd exposure model; 60 chickens were treated with Cd (0 mg/kg, 35 mg/kg, 70 mg/kg) for 90 days. Clinical manifestations indicated that the chicken was depressed and has unstable gait under Cd exposure. Histopathological results indicated that Cd induced neuronal shrunken and indistinct nucleoli, and the number of Purkinje cells decreased significantly. Cerebellar metal contents were analyzed by ICP-MS. We found that Cd caused Cd and Cu accumulation and decreased the content of Se, Fe, and Zn, suggesting that Cd disturbed metal homeostasis. Besides, Cd treatment group also showed high levels of malondialdehyde (MDA) and hydrogen peroxide (H 2 O 2 ) content and inhibited selenoprotein transcriptome, suggesting that Cd exposure resulted in oxidative stress. Notably, low-dose Cd exposure activated MTF1 mRNA and protein expression and its target metal-responsive genes, including MT1, MT2, DMT1, ZIP8, ZIP10, TF, and ATP7B which indicate cellular adaptive response against Cd-induced damage. On the other hand, 70 mg/kg Cd downregulated MTF1-mediated metal response, which was involved in Cd-induced cerebellar injury in chicken. In conclusion, our data demonstrated that molecular mechanisms are associated with Cd-induced cerebellar injury due to disturbing MTF1-mediated metal response. This study indicated that the cerebellum is one of the target organs of Cd-induced toxicity. Additionally, Cd exposure induced metal dyshomeostasis in chicken's cerebellum, whereas this study found that lower level of Cd dose triggered the activation of the cytoprotective mechanism through activating the expression of MTF1 which regulate MT1, MT2, DMT1, ZIP8, ZIP10, TF, and ATP7B expressions in cerebellum. However, MTF1-mediated metal response was inhibited under the exposure of high dose of Cd, which ultimately caused cerebellar injury. The present study provides a new insight that Cd through disturbed MTF1-mediated metal response disrupts metal homeostasis that induced cerebellar injury., (© 2022.

Objective: Rheumatoid wrist arthritis is a chronic autoimmune disease, resulting in joint deformity and functional impairment. We aimed to compare the wrist synovial ultrasound indices and serum vascular endothelial growth factor (VEGF) level in patients with RA before and after treatment, and to explore the correlation between the two., Methods: Forty patients with RA in wrist underwent ultrasound examination to determine wrist synovial thickness, synovial blood flow grade, and synovial artery resistive index (RI) before and after treatment. The serum level of VEGF was detected by enzyme-linked immunosorbent assay. Correlation between synovial ultrasound indices and serum VEGF level was assessed., Results: Pre-treatment synovial thickness, synovial artery RI, and serum VEGF level were 8.60 ± 2.82 mm, 0.62 ± 0.07, and 419.49 ± 19.27 pg/mL, respectively. The corresponding post-treatment levels were 4.05 ± 1.89 mm, 0.83 ± 0.10, and 199.30 ± 16.18 pg/mL. Pre-treatment distribution of synovial blood flow grades was as follows: grade 0, nil; grade I, 1 case; grade II, 17 cases; grade III, 22 cases. The post-treatment distribution was as follows: grade 0, 6 cases; grade I, 23 cases; grade II, 11 cases; and grade III, nil. There were significant differences between pre- and post-treatment wrist synovial thickness, artery RI, and blood flow grading. Wrist synovial thickness and synovial blood flow grade showed a strong positive correlation with serum VEGF level (P < 0.01). There was strong negative correlation between wrist synovial artery RI and serum VEGF level (P < 0.01)., Conclusion: The strong correlation between wrist synovial ultrasound indicators and serum VEGF may be clinically useful for diagnosis and therapy., (© 2022.

Background: It remains inconclusive whether laparoscopic gastrectomy (LG) has better long-term outcomes when compared with open gastrectomy (OG) for elderly gastric cancer (EGC). We attempted to explore the influence of the immune prognostic index (IPI) on the prognosis of EGCs treated by LG or OG to identify a population among EGC who may benefit from LG., Methods: We included 1539 EGCs treated with radical gastrectomy from January 2007 to December 2016. Propensity score matching was applied at a ratio of 1:1 to compare the LG and OG groups. The IPI based on dNLR ≥ cut-off value (dNLR) and sLDH ≥ cut-off value (sLDH) was developed, characterizing two groups (IPI = 0, good, 0 factors; IPI = 1, poor, 1 or 2 factors)., Results: Of the 528 EGCs (LG: 264 and OG: 264), 271 were in the IPI = 0 group, and 257 were in the IPI = 1 group. In the entire cohort, the IPI = 0 group was associated with good 5-year overall survival (OS) (p = 0.001) and progression-free survival (PFS) (p = 0.003) compared to the IPI = 1 group; no significant differences in 5-year OS and PFS between the LG and OG groups were observed. In the IPI = 1 cohort, there was no significant difference in OS or PFS between the LG and OG groups across all tumor stages. However, in the IPI = 0 cohort, LG was associated with longer OS (p = 0.015) and PFS (p = 0.018) than OG in stage II EGC, but not in stage I or III EGC. Multivariate analysis showed that IPI = 0 was an independent protective factor for stage II EGC receiving LG, but not for those receiving OG., Conclusion: The IPI is related to the long-term prognosis of EGC. Compared with OG, LG may improve the 5-year survival rate of stage II EGC with a good IPI score. This hypothesis needs to be further confirmed by prospective studies., (© 2021.

Background: Pancreatic cancer (PC) is one of the most lethal cancer types with an extremely poor diagnosis and prognosis. This study aimed to comprehensively analyze the relationships between PC and different gene classes., Methods: Numerous genes from different categories were selected from the UALCAN database. Expression and survival analysis of these genes were performed via GEPIA, starBase and Kaplan-Meier Plotter tools. The correlations between PC-related genes and frequently mutated genes in PC as well as myeloid-derived suppressor cells (MDSCs) infiltration levels were explored by TIMER tool. The associations between PC-related genes, immune checkpoints and 182 core cancer-intrinsic CTLs-evasion genes were analyzed by R software. Besides, KEGG analysis were performed for the PC-related genes., Results: 14 genes were identified to be highly expressed in pancreatic cancer and significantly associated with poor prognosis. Besides, high expression of these genes were observed in patients with KRAS or TP53 mutations. Most genes were significantly positively associated with immune checkpoint SIGLEC15, however, showed negative relations to PDCD1, CTLA4, LAG3, TIGIT, PDCD1LG2. In addition, all 14 genes exhibited close relationships with MDSC infiltration levels and various core cancer-intrinsic CTLs-evasion genes, especially DNTTIP1, FADD, ARF6, BCL2L1, CEP55, GALE, PDCD6IP, and RCE1. We also explored the most related pathways with these genes to further reveal the pathogenesis and metastatic mechanisms of PC., Conclusion: Our study analyzed the relationships between 14 PC-related genes and pancreatic cancer from different angles, which may contribute to a better understanding of unsolved mystery in PC., (© 2021.

Background: The oncologic efficacy of laparoscopic versus open surgery for advanced distal gastric cancer (ADGC) beyond 3 years after surgery remain obscure., Methods: A total of 1256 patients with ADGC at two teaching institutions in China from April 2007 to December 2014 were enrolled. The general data of the two groups were identified to enable rigorous estimation of propensity scores. Restricted mean survival time (RMST) and Landmark analysis was used to compare survival., Results: After matching 461 patients each in the open distal gastrectomy (ODG) and laparoscopic distal gastrectomy (LDG) groups, they were included into analysis. The 3- and 5-year overall survival (OS) and disease-free survival were comparable in two groups. RMST-stratified analysis showed that the 3-year RMST of ODG group was similar to that of LDG group in patients with cT4a (- 1.38 years, p = 0.163) or with cT4a and tumor size > 5 cm, whereas the 5-year RMST had significant differences between groups in cT4a patients(- 8.36 years, P = 0.005) or cT4a and tumor size > 5 cm patients(4.67 years, P = 0.042). In patients with cT4a and tumors > 5 cm, the number of peritoneal recurrences was significantly fewer in the ODG group than in the LDG group (4 vs. 17, P = 0.033), and the peritoneal recurrence time and multiple-site recurrence time were both later in the ODG group., Conclusion: By reducing recurrence, ODG achieves a better survival for GC patients with serous infiltration and tumors larger than 5 cm beyond 3 years after surgery. The present findings can serve as a reference for surgical options and the setting of follow-up time point for clinical studies., (© 2021. The Author(s).)

Purpose: This study evaluates the impact of second-opinion review of multiparametric prostate MRI for cancer detection by a multidisciplinary review board at a tertiary care center when compared with the initial community radiologist interpretation., Methods: Cases were collected retrospectively from multidisciplinary prostate MRI rounds from 2017 to 2020 at a single tertiary care center. Patients with suspected prostate cancer or on active surveillance were referred for consideration of TRUS/MRI-fusion biopsy based on community-read prostate MRIs. All MRIs were re-read by subspecialized abdominal radiologists and a PI-RADS score assigned. Targeted fusion and 8-12 core systematic biopsy was performed in patients with PIRADS ≥ 3 lesions. Cohen kappa values were used to quantify interobserver agreement. Positive predictive value (PPV) was used to determine accuracy of PI-RADS score for detection of clinically significant prostate cancer (csPCa) (ISUP Grade Group ≥ 2)., Results: Three hundred and thirty-two lesions in 303 patients were reviewed and 252 lesions in 198 patients biopsied. The PI-RADS score was concordant in 60.5% of lesions, downgraded in 17.8%, and upgraded in 7.8%. Agreement between community and tertiary center interpretation was fair (κ = 0.354), with greater agreement for PI-RADS ≥ 4 (κ = 0.523) than PI-RADS ≥ 3 (κ = 0.456), and peripheral zone (κ = 0.419) than transition zone lesions (κ = 0.251). Prevalence of csPCa in biopsied lesions was 40.9%., Conclusion: There is variability in community and tertiary care center interpretation of prostate MRI in cancer detection, with higher concordance rates for higher grade and peripheral zone lesions. These differences demonstrate the added value of multidisciplinary round review and highlight the need for ongoing education and feedback., (© 2021.

Two novel species of the genus Deinococcus, designated SYSU M49105 T and SYSU M42101 T , were isolated from freshwater samples of the Pearl River estuary in Guangdong, China. Phylogenetic analysis using 16S rRNA gene sequence indicated that strains SYSU M49105 T and SYSU M42101 T showed the highest sequence similarities to Deinococcus aetherius JCM 11751  T (93.6%) and Deinococcus multiflagellatus NBRC 112888  T (97.3%), respectively. Cells of both strains were Gram-staining positive, aerobic, coccus-shaped, oxidase-negative and non-motile. The cell wall contained meso-diaminopimelic acid as their diagnostic diamino acid. MK-8 was the predominant respiratory quinone for both strains. The polar lipid profile of SYSU M49105 T contained two unidentified phosphoglycolipids, nine unidentified glycolipids, and five unidentified polar lipids. SYSU M42101 T had one unidentified phosphoglycolipid, nine unidentified glycolipids, one unidentified aminophospholipid and four unidentified polar lipids. The major fatty acids of strains SYSU M49105 T and SYSU M42101 T were summed feature 3 (C 16:1 ω7c and/ or C 16:1 ω6c) and C 16:0. The G + C contents of the novel isolates based on genomic DNAs were 69.6% and 67.4%, respectively. On the basis of phenotypic, genotypic and phylogenetic data, strains SYSU M49105 T and SYSU M42101 T should be considered to represent two novel species in the genus Deinococcus, for which the names Deinococcus aestuarii sp. nov. and Deinococcus aquaedulcis sp. nov. were proposed with the type strains SYSU M49105 T (= KCTC 43258  T  = CGMCC 1.18609  T ) and SYSU M42101 T (= KCTC 43257  T  = CGMCC 1.18614  T ), respectively., (© 2021.

Electrochemical reduction of CO 2 to formate is economically attractive but improving the reaction selectivity and activity remains challenging. Herein, we introduce boron (B) atoms to modify the local electronic structure of bismuth with positive valence sites for boosting conversion of CO 2 into formate with high activity and selectivity in a wide potential window. By combining experimental and computational investigations, our study indicates that B dopant differentiates the proton participations of rate-determining steps in CO 2 reduction and in the competing hydrogen evolution. By comparing the experimental observations with the density functional theory, the dominant mechanistic pathway of B promoted formate generation and the B concentration modulated effects on the catalytic property of Bi are unravelled. This comprehensive study offers deep mechanistic insights into the reaction pathway at an atomic and molecular level and provides an effective strategy for the rational design of highly active and selective electrocatalysts for efficient CO 2 conversion., (© 2021.

Post traumatic stress disorder (PTSD) is a mental health condition that has a debilitating effect on a person's quality of life and leads to a high socioeconomic burden. Licorice has been demonstrated to have neuroprotective and antidepressant-like effects, but little is known about its effects for the treatment of PTSD. The present study aimed to explore the potential of licorice for PTSD therapy using a network pharmacology approach with molecular docking studies. The compounds of licorice were obtained from databases with screening by absorption, distribution, metabolism and excretion (ADME) evaluation. Genes associated with compounds or PTSD were obtained from public databases, and the genes overlapping between licorice compounds and PTSD were compared by Venn diagram. A network of medicine-ingredients-targets-disease was constructed, visualized, and analyzed using cytoscape software. Protein-protein interactions, gene ontology, pathway enrichment and molecular docking were performed to evaluate the effect of licorice for the treatment of PTSD. 69 potential compounds were screened after ADME evaluation. A total of 81 compound-related genes and 566 PTSD-related genes were identified in the databases with 27 overlapping genes. Licorice compounds (e.g., medicarpin, 7-methoxy-2-methyl isoflavone, shinpterocarpin, formononetin, licochalcone a) and target proteins (e.g., ESR1, PTGS2, NOS2, and ADRB2) with high degree in the network were involved in G protein-coupled receptor signaling pathways at the postsynaptic/synaptic membrane. Moreover, neuroactive ligand-receptor interactions, calcium signaling, cholinergic synapse, serotonergic synapse and adrenergic signaling in cardiomyocytes may play important roles in the treatment of PTSD by licorice. This study provides molecular evidence of the beneficial effects of licorice for the treatment of PTSD., (© 2021.

Background: The application of splenic hilar lymph node (no. 10 LN) dissection (no. 10 LND) for proximal gastric cancer (PGC) remains controversial. This study aimed to investigate the clinical relevance of no. 10 LND from the perspective of long-term survival., Methods: The main study population included 995 previously untreated patients who underwent laparoscopic radical total gastrectomy between January 2008 and December 2014. Of these 995 patients, 564 underwent no. 10 LND (no. 10D+ group) and the remaining 431 patients did not (no. 10D- group). Propensity score-matching was applied to reduce the effects of confounding factors. The study end points were overall survival (OS) and disease-free survival (DFS). Additionally, 39 patients who received neoadjuvant chemotherapy during the same period also were included as a separate population for analysis., Results: The metastasis rate for no. 10 LN was 10.5 % (59/564). No significant differences were observed in intra- and postoperative complications nor in mortality between the no. 10D+ and no. 10D- groups (all P > 0.05). After 1:1 matching, the two groups were comparable in clinicopathologic characteristics. The no. 10D+ group had significantly better survival than the no. 10D- group (5-year OS: 63.3 % vs 52.2 %, P = 0.003; 5-year DFS: 60.4 % vs 48.1 %, P = 0.013). For the patients who received neoadjuvant chemotherapy, the 5-year OS rates in the no. 10D+ and no. 10D- groups were respectively 50.6 % and 31.3 % (P = 0.150) and the 5-year DFS rates were respectively 51.5 % and 31.3 % (P = 0.123)., Conclusions: Patients with untreated PGC may achieve the benefit of long-term survival from no. 10 LND. For patients with PGC who undergo neoadjuvant chemotherapy, no. 10 LND may not bring survival benefits. However, further validation with a large-sample study is needed., (© 2021.

SATB2-associated syndrome (SAS) is a multisystemic disorder characterized by developmental delay often with concurrent autistic tendencies. This study aimed to characterize cellular metabolic pathways and energy metabolism from cells derived from individuals with SAS. The cellular production of NADH (nicotinamide adenine dinucleotide, reduced form) as determined by the Phenotype Mammalian MicroArrays was measured in lymphoblastoid cell lines derived from 11 subjects with a molecularly confirmed diagnosis of SAS and compared to a control population of 50 age-matched typically developing individuals. All patients were evaluated clinically by a multidisciplinary team. Eleven individuals (five in a screening cohort and six in the validation cohort, mean age 6.1 years) were recruited to the study. All individuals had developmental delay and the diagnosis of autism was previously established in five of them. Key metabolic findings included reduced NADH production in the presence of phosphorylated carbohydrates (with corresponding increased production in the presence of alternative carbon-based energy sources), increased response to certain hormones (β-estradiol in particular), and significantly reduced levels of NADH in wells containing tryptophan. The individual analysis revealed no particular differences among the SAS subjects based on molecular findings or phenotypic features. In conclusion, individuals with SAS have a common and recognizable metabolic profile. A lower capacity to utilize glucose as an energy substrate could be contributing to the neurodevelopment phenotype of SAS. The identified abnormalities offer previously unexplored insight into the potential pathophysiology of common SAS phenotypic features.

Cost-efficient and environmentally friendly treatment of hydraulic fracturing effluents is of great significance for the sustainable development of shale gas exploration. We investigated the synergistic effects of plant-microbial treatment of shale gas fracturing waste fluid. The results showed that illumination wavelength and temperature are direct drivers for microbial treatment effects of COD Cr and BOD 5 , while exhibit little effects on nitrogen compounds, TDS, EC, and SS removals as well as microbial species and composition. Plant-microbial synergism could significantly enhance the removal of pollutants compared with removal efficiency without plant enhancement. Additionally, the relative abundance and structure of microorganisms in the hydraulic fracturing effluents greatly varied with the illumination wavelength and temperature under plant-microbial synergism. 201.24 g water dropwort and 435 mg/L activated sludge with illumination of 450-495 nm (blue) at 25 °C was proved as the best treatment condition for shale gas fracturing waste fluid samples, which showed the highest removal efficiency of pollutants and the lowest algal toxicity in treated hydraulic fracturing effluents. The microbial community composition (36.73% Flavobacteriia, 25.01% Gammaproteobacteria, 18.55% Bacteroidia, 9.3% Alphaproteobacteria, 4.1% Cytophagia, and 2.83% Clostridia) was also significantly different from other treatments. The results provide a potential technical solution for improved treatment of shale gas hydraulic fracturing effluents.

Objective: This study aimed to compare the long-term outcome of endotherapy versus a combination of splenectomy and devascularization for variceal bleeding in patients with hepatitis B-related cirrhosis (HBRC)., Materials and Methods: A total of 1074 patients with HBRC and acute variceal bleeding (AVB) treated with endotherapy and 248 patients with HBRC treated with a combination of splenectomy and devascularization surgery were included in the analysis. After one-to-one propensity score matching, 151 paired patients were selected. The primary end-point was death. The secondary outcomes were 3-year survival, 5-year survival, and rebleeding. Complications were recorded., Results: The median follow-up time was 1165 days in the endoscopic group and 1709 days in the surgical group. Before matching, the 1-year, 3-year, and 5-year survival rates were significantly lower in the endoscopic group than in the surgical group (91.1 vs 96.3%, P = 0.017; 79.6 vs 91.6%, P = 0.001; 65.2 vs 81.3%, P = 0.001). After matching, no significant differences were found between groups (94.5 vs 95.2%, P = 0.767; 87.0 vs 88.9%, P = 0.635; 77.9 vs 77.9%, P = 0.905). The rebleeding rate was lower in the surgical group than in the endoscopic group; the rebleeding-free survival rate was similar in the two groups. No patient died of complications. No statistically significant difference was observed in complications between groups., Conclusions: Both endotherapy and a combination of splenectomy and devascularization are good choices for patients with AVB. The rebleeding rate was lower after the surgical procedure, but the long-term prognosis was similar.

Efficient and robust single-atom catalysts (SACs) based on cheap and earth-abundant elements are highly desirable for electrochemical reduction of nitrogen to ammonia (NRR) under ambient conditions. Herein, for the first time, a Mn-N-C SAC consisting of isolated manganese atomic sites on ultrathin carbon nanosheets is developed via a template-free folic acid self-assembly strategy. The spontaneous molecular partial dissociation enables a facile fabrication process without being plagued by metal atom aggregation. Thanks to well-exposed atomic Mn active sites anchored on two-dimensional conductive carbon matrix, the catalyst exhibits excellent activity for NRR with high activity and selectivity, achieving a high Faradaic efficiency of 32.02% for ammonia synthesis at  - 0.45 V versus reversible hydrogen electrode. Density functional theory calculations unveil the crucial role of atomic Mn sites in promoting N 2 adsorption, activation and selective reduction to NH 3 by the distal mechanism. This work provides a simple synthesis process for Mn-N-C SAC and a good platform for understanding the structure-activity relationship of atomic Mn sites.

Purpose: Inconsistent results of lipid-lowering medications (LLMs) on improved cancer survival need more investigations. We tested the hypothesis that adherence to the drug would be associated with a lower cancer-specific mortality in a homogeneous population who has ever used the drug., Methods: Utilising data from the Australian Cancer database, linked to the Pharmaceutical Benefits Scheme data and the National Death Index, we identified two separate cohorts of 4519 and 3083 women patients with newly diagnosed endometrial and lung cancer respectively between 2003 and 2013. Adherence to this drug was calculated by proportion of days covered. Cox regression models with time-varying covariates were used to estimate the multivariable-adjusted cause-specific hazard ratios (HRs) and 95% confidence intervals (CIs) for the association of adherence to LLMs, statins, lipophilic and hydrophilic statins, and cancer-specific mortality., Results: Each 10% increase in 1-year adherence to LLMs reduced cancer-specific mortality among women with endometrial cancer (adjusted HR=0.93, 95% CI 0.90-0.96) or lung cancer (adjusted HR=0.95, 95% CI 0.93-0.97). The inverse associations remained unchanged in different subgroup analyses. The reductions in lung cancer mortality were not apparent for women who adhered to lipophilic statins albeit better endometrial cancer survival appeared in the lipophilic statin group and borderline statistical improvement in the hydrophilic statin group., Conclusions: Among LLM users, adherence to this drug is inversely associated with reduced cancer-specific mortality. Together with previous evidence, randomised controlled trials are called for to confirm whether LLMs could be considered as an adjuvant treatment to improve prognosis.

Background: Whether the change of the pre- and postoperative systemic inflammatory response (SIR) levels will affect the prognosis of gastric cancer (GC) is unclear. We aimed to investigate the dynamic changes in the pre- and postoperative SIR and their prognostic value for GC., Methods: The clinicopathological data from 2257 patients who underwent radical gastrectomy between January 2009 and December 2014 at Fujian Medical University Union Hospital (FMUUH) were analyzed. Perioperative SIR changes were reported as changes in the lymphocyte-monocyte ratio (LMR), neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and systemic immune-inflammation index (SII)., Results: The SIR levels showed different trends from postoperative months 1 to 12. Multivariate analysis showed that preoperative (pre)-LMR was an independent predictor for the prognosis (P = 0.024). The postoperative 12-month (post-12-month) LMR predicted the 5-year overall survival (OS) rate with the highest accuracy (areas under the curve [AUC] 0.717). Patients were divided into four groups according to the optimal cutoff of the preoperative and post-12-month LMR: high pre-LMR to high postoperative (post)-LMR group, high pre-LMR to low post-LMR group, low pre-LMR to high post-LMR group, and low pre-LMR to low post-LMR group. The survival analysis showed 5-year OS rate was significantly higher in patients with high post-12-month LMR than in patients with low post-12-month LMR, regardless of pre-LMR levels (81.6% vs. 44.2%, P < 0.001). The prognostic accuracy was significantly improved by incorporating the post-12-month LMR in the tumor-node-metastasis (TNM) staging system (P = 0.003)., Conclusions: The remeasurement of LMR at post-12-month is helpful in predicting the long-term survival of GC.

Four experiments investigated the extent to which a limited pool of resources can be shared between different tasks performed simultaneously when it is efficient to do so. The experiments used a prioritized processing paradigm, in which stimuli for both a primary task and a background task were presented in each trial. If the primary-task stimulus required a response in a trial, participants made only that response. If the primary-task stimulus did not require a response, participants responded to the background task. The main manipulation was the relative probability that a response would be required to the primary versus background task. In some blocks, the majority of trials required responses to the primary task (Experiments 1 and 2: 80%; Experiments 3 and 4: 60%), whereas in other blocks the majority required responses to the background task. Background-task responses were substantially faster in blocks where they were more likely to be required, consistent with the idea that more capacity was allocated to them in these blocks. Backward compatibility effects on primary-task responses and stimulus-onset asynchrony effects on background-task responses provided further evidence of greater capacity allocation to the background task when there was a higher probability of responding to it. The results support the view that two tasks can be processed in parallel, with resources divided between them, when it is efficient to do so.

In the context of the rapid development of the Belt and Road (B&R) Initiative, the continuous transfer of Sino-US trade to the B&R countries is an important means to mitigate the threat of Sino-US trade, and the environmental impact of this transfer should be considered, so as to provide a scientific basis for China's policy formulation about achieving this possible trade transfer with minimized environmental impacts. This study proposes a multiregional input-output model and analyzes the impact on carbon dioxide (CO 2 ) emissions of transferring the Sino-US trade to the B&R countries for two types of scenarios. The results show the following: (1) A transfer of either the import trade or the export trade increases global and Chinese CO 2 emissions by 81.76 Mt and 24.84 Mt, respectively. When both the import trade and export trade are transferred, the increases in CO 2 emissions are only 0.22% and 0.26%, respectively. (2) Globally, the changes in international trade-embodied CO 2 emissions are responsible for most of the global emission changes, especially the CO 2 emissions exported from Russia, India, and many Southeast Asian countries to China. (3) Different from the impact on global emissions, the increases in Chinese domestic production-based CO 2 emissions influence China's total CO 2 emissions. Due to the imported CO 2 emissions, the consumption-based CO 2 emissions are affected to a greater degree and increase by 70.30 Mt, accounting for only 0.86% of the CO 2 emissions in 2015. Finally, some policy implications are proposed.

Background: Well-designed retrospective studies (RSs) and small-sample prospective studies (PSs) evaluating the efficacy of interventions have received much attention. This study was designed to evaluate the differences between well-designed RSs and small-sample randomized controlled trials based on the efficacy of laparoscopic distal gastrectomy (LDG) and open distal gastrectomy (ODG) for advanced gastric cancer (GC)., Methods: The clinicopathological data of 1360 patients with GC who underwent DG were analysed. After propensity score matching (1:1), 380 cases (ODG = 190, LDG = 190) were finally selected in a RS. Meanwhile, data from 120 patients (ODG = 60, LDG = 60) who enrolled in a PS were analysed., Results: In the PS, the LDG group had less intraoperative blood loss, shorter time to first flatus, and shorter time to fluid diet than the ODG group. In the RS, the LDG group had less intraoperative blood loss, and a shorter postoperative hospital stay than the ODG group. In the PS, the 3-year overall survival (OS) rate was 83.3% in the LDG group and 83.2% in the ODG group (p = 0.877). In the RS, the 3-year OS rate was 68.7% in the LDG group and 66.6% in the ODG group (p = 0.752). No significant interactions were observed between the two groups and any of the variables examined, either in the PS or RS. The recurrence patterns were similar in the two groups. Furthermore, Cox regression analysis showed that surgical method (LDG/ODG) was not a prognostic factor affecting OS or DFS, either prospectively or retrospectively., Conclusions: The oncologic efficacy of laparoscopic and open distal gastrectomy for advanced GC is comparable. Well-designed RSs can be similar to small sample of PSs in assessing long-term oncologic outcomes of surgical interventions, but the short-term outcomes obtained should be treated with caution.

Left ventricular diastolic dysfunction (LVDD) remains challenging to be assessed by echocardiography. We sought to explore the relationship between left atrial strain and left ventricular (LV) diastolic function in patients with normal left ventricular ejection fraction (LVEF) by invasive left-heart catheterization. 55 consecutive individuals with LVEF > 50% underwent LV catheterization. Standard transthoracic echocardiography was performed during 12 h before or after the procedure. Left atrial (LA) strain were obtained by speckle tracking echocardiography. When LVEF ≥ 50%, the group with elevated left ventricular end-diastolic pressure (LVEDP) (n = 35) showed decreased left atrial reservoir strain (LASr) (35.2 ± 7.7% vs 21.3 ± 7.2%, p < 0.001), left atrial conduit strain (LASct) (17.6 ± 6.3% vs 11.9 ± 4.1%, p < 0.001), left atrial contraction strain (LAScd) (16.6 ± 7.2% vs 9.5 ± 5.0%, p < 0.001) and increased E/e' ration(8.9 ± 2.6 vs 10.1 ± 3.5, p = 0.17). LVEDP negatively correlated with LASr (R = 0.662, p < 0.001), LASct (R = 0.575, p < 0.001) and LAScd (R = 0.456, p < 0.001), but not with E/e'. LASr, LASct and LAScd were all independent predictors of elevated LVEDP (p < 0.05), with a higher C-statistic for the model including LASr (0.95, 0.86 and 0.93 respectively). The area under the curve (AUC) for LASr is 0.914 (cutoff value is 26.7%, sensitivity is 90%, specificity is 82.9%). In patients with normal LV ejection fraction, left atrial strain presented good correlation with LVEDP, and LASr was superior to LASct and LAScd to predict LVEDP. LA strain demonstrated better agreement with the invasive reference than E/e'.

The molecular mechanisms underlying colon cancer lesions at different sites are not entirely clear. Herein, we aimed to explore location-specific gene profiles related to the pathogenesis of colon cancer and to identify their function. The robust rank aggregation (RRA) method was used to integrate colon cancer microarray datasets and screen differentially expressed gene (DEG) profiles between left- and right-sided colon cancers. Then, weighted gene co-expression network analysis (WGCNA) was performed to cluster the DEGs into modules and identify hub genes. The selected hub genes were validated using The Cancer Genome Atlas dataset and clinical tissues. We assessed the association of selected hub genes with the methylation status in immune cells. In total, 905 DEGs were identified by RRA; five gene modules and 18 hub genes were related to the clinical traits of colon cancer by WGCNA. Four hub genes were selected and shown to be associated with colon cancers on different sides and distant metastasis in the validation analysis. The four hub genes showed a low methylation status, and their expression was significantly associated with methylation status. Positive correlations were observed between the four hub genes and tumor purity and among the four types of immune cells. Gene set enrichment analysis revealed that the four hub genes were mainly involved in two cancer-related pathways. In conclusion, this study identified a set of location-specific genes related to the pathogenesis of colon cancer. These four hub genes may act as novel candidate targets for the treatment of colon cancer.
