In the rapidly advancing realm of perovskite solar cells, the rectification of defects has surfaced as a crucial scientific challenge. The control over defect states, especially in printable mesoscopic perovskite solar cells (p‐MPSCs), is hindered by the complexities of screen‐printing technology. Here a novel "two‐in‐one" defect passivation strategy is presented, through doping TiO2 paste with cesium halide salts (CsX, where X = F, Cl, Br, I) to integrate all‐inorganic Cs halides, particularly CsF, into the electron transport layer in p‐MPSCs. Owing to the robust interaction between F− ions and TiO2 compared to Cs+ ions, and the inability of F− to infiltrate the perovskite lattice, F− and Cs+ play distinct roles starting from the buried interface of the p‐MPSCs. Specifically, F− can rectify the oxygen vacancies on the TiO2 surface, thus alleviating the residual stress at the perovskite's buried interface. Simultaneously, Cs+ diffuses to the top perovskite and mends the methylamine vacancies. As a result, the PCE of the optimal device, based on F‐doped TiO2, witnesses a significant improvement from 16.18% (control) to 18.24%. The two‐in‐one strategy utilizing CsX from the buried interface can well realize the all‐inorganic defect rectification, thereby offering a promising prospect for the enhancement of p‐MPSC performance.

The relationship among polycystic ovary syndrome (PCOS), endometrial cancer (EC), and glycometabolism remains unclear. We explored shared genes between PCOS and EC, using bioinformatics to unveil their pathogenic connection and influence on EC prognosis. Gene Expression Omnibus datasets GSE226146 (PCOS) and GSE196033 (EC) were used. A protein–protein interaction (PPI) network was constructed to identify the central genes. Candidate markers were screened using dataset GSE54250. Differences in marker expression were confirmed in mouse PCOS and human EC tissues using RT‐PCR and immunohistochemistry. The effect of PGD on EC proliferation and migration was explored using Ki‐67 and Transwell assays. PGD's impact on the glycometabolic pathway within carbon metabolism was assessed by quantifying glucose content and lactic acid production. R software identified 31 common genes in GSE226146 and GSE196033. Gene Ontology functional classification revealed enrichment in the "purine nucleoside triphosphate metabolism process," with key Kyoto Encyclopedia of Genes and Genomes pathways related to "carbon metabolism." The PPI network identified 15 hub genes. HK2, NDUFS8, PHGDH, PGD, and SMAD3 were confirmed as candidate markers. The RT‐PCR analysis validated distinct HK2 and PGD expression patterns in mouse PCOS ovarian tissue and human EC tissue, as well as in normal and EC cells. Transfection experiments with Ishikawa cells further confirmed PGD's influence on cell proliferation and migration. Suppression of PGD expression impeded glycometabolism within the carbon metabolism of EC cells, suggesting PGD as a significant PCOS risk factor impacting EC proliferation and migration through modulation of single carbon metabolism. These findings highlight PGD's pivotal role in EC onset and prognosis. [ABSTRACT FROM AUTHOR]

Objective: The present study conducted a meta‐analysis to synthesize the associations between sexual minority stress and relationship satisfaction, as well as to examine actor and partner effects. Background: Sexual minority individuals in same‐sex couples experience various distinct and chronic stressors related to their stigmatized identities and romantic relationships, and these stressors negatively impact relationship satisfaction. Although there have been two meta‐analyses that sought to examine these influences, some fundamental questions remain unanswered. In particular, the roles of dyadic processes and different types of sexual minority stressors remain unclear. Method: A comprehensive search identified 67 studies with 147 effect sizes representing 24,542 individuals. Results: The results revealed a significant small association (r = −.100 to −.188) between sexual minority stressors and relationship satisfaction. Internalized stressors were more strongly associated with relationship satisfaction than other types of sexual minority stressors (e.g., prejudice events and concealment). Dyadic analyses demonstrated a significant actor effect of concealment, experiencing prejudice events, and internalized stressors on relationship satisfaction, with the largest effect size for concealment effects. Conclusion: These findings suggest that sexual minority stressors could potentially contribute to same‐sex relational problems. They also underscore the importance of interdependence (both partners' responses as well as their interaction with sexual minority stressors). This understanding may be instrumental in shaping prevention strategies. Implications: The meta‐analysis emphasizes the nuanced impact of sexual minority stressors on same‐sex relationship satisfaction, highlighting the importance of targeted interventions. It underscores the role of dyadic processes, emphasizing the significance of both partners' responses and interactions with stressors in developing effective prevention strategies for healthier same‐sex relationships.

Nutrient cycling in desert ecosystems is heavily reliant on the fine root turnover and litter decomposition processes of dominant plant species. Based on field investigations and laboratory experiments, we explored fine root production (FRP) and turnover of Salsola passerina in Alxa steppe desert, and assessed fine root and leaf litter input and its correlation with soil C and N stocks, and then compared the variability of soil physicochemical properties at the site below and the interspace of S. passerina canopy. Results showed that fine root biomass dynamics of S. passerina were consistent with soil water content. Annual FRP of S. passerina was 243.3 g m−2 yr−1 and the turnover rate was 2.0 per year. S. passerina contributed 172.2 g C m−2 and 6.8 g N m−2 to soil from its fine root senescence and leaf litter input annually. Compared to the canopy interspace, the soil texture and fertility beneath the shrubs significantly improved, while the soil salinity decreased. The results indicated that the activities of desert shrub growth provided the degraded soil with abundant nutrients through fine root turnover and litter decomposition processes, which promoted soil texture and nutrition heterogeneity at the stand scale, and played an important role in degraded dryland restoration.

Flexible circularly polarized luminescence (CPL) exhibits significant potential for applications in smart wearable devices and high‐end anti‐counterfeiting. However, existing technologies suffer from low dissymmetry factor (glum) and poor mechanical reliability. Here, a metal halide perovskite is employed as the emitter to construct efficient and robust flexible CPL films through a facile strategy of bilayer stacking, which comprises a layer of perovskite nanocrystalline embedded polymer film and a layer of photonic crystal film based on polymerized chiral liquid crystals (LCs). The photoluminescence efficiency of perovskite nanocrystals in polyacrylonitrile (PAN) matrix is improved by incorporating an appropriate amount of phenylethylammonium bromide (PEABr) as a passivation agent, and the helical arrangement and optical activity of free‐standing flexible photonic crystal films are found to be highly related to the supporting substrates. Upon stacking, the resulting flexible composite film exhibits extremely high |glum| values of up to 1.81, representing the highest value among reported flexible CPL‐active films. Moreover, the composite films demonstrate remarkable mechanical robustness, which shows negligible degradation in terms of glum value even after 1000 bending cycles at a bending radius of 2 mm. Based on the flexible CPL‐active films, advanced anti‐counterfeit labels with switchable patterns under circular polarizers are demonstrated. [ABSTRACT FROM AUTHOR]

Mesenchymal stem cells (MSCs) reveal multifaceted immunoregulatory properties, which can be applied for diverse refractory and recurrent disease treatment including acute graft‐versus‐host disease (aGVHD). Distinguishing from MSCs with considerable challenges before clinical application, MSCs‐derived exosomes (MSC‐Exos) are cell‐free microvesicles with therapeutic ingredients and serve as advantageous alternatives for ameliorating the outcomes of aGVHD. MSC‐Exos were enriched and identified by western blotting analysis, NanoSight, and transmission electron microscopy (TEM). Bone marrow–derived MSCs (denoted as MSCs) and exosomes (denoted as MSC‐Exos) were infused into the aGVHD SD‐Wister rat model via tail vein, and variations in general growth and survival of rats were observed. The level of inflammatory factors in serum was quantized by enzyme‐linked immunosorbent assay (ELISA). The pathological conditions of the liver and intestine of rats were observed by frozen sectioning. The ratios of CD4+/CD8+ and Treg cell proportions in peripheral blood, together with the autophagy in the spleen and thymus, were analyzed by flow cytometry. After treatment with MSC‐Exos, the survival time of aGVHD rats was prolonged, the clinical manifestations of aGVHD in rats were improved, whereas the pathological damage of aGVHD in the liver and intestine was reduced. According to ELISA, we found that MSC‐Exos revealed ameliorative effect upon aGVHD inflammation (e.g., TNF‐α, IL‐2, INF‐γ, IL‐4, and TGF‐β) compared to the MSC group. After MSC‐Exo treatment, the ratio of Treg cells in peripheral blood was increased, whereas the ratio of CD4+/CD8+ in peripheral blood and the autophagy in the spleen and thymus was decreased. MSC‐Exos effectively suppressed the activation of immune cells and the manifestation of the inflammatory response in the aGVHD rat model. Our data would supply new references for MSC‐Exo‐based "cell‐free" biotherapy for aGVHD in future. [ABSTRACT FROM AUTHOR]

Background: The number of multigene‐modified donor pigs for xenotransplantation is increasing with the advent of gene‐editing technologies. However, it remains unclear which gene combination is suitable for specific organ transplantation. Methods: In this study, we utilized CRISPR/Cas9 gene editing technology, piggyBac transposon system, and somatic cell cloning to construct GTKO/hCD55/hTBM/hCD39 four‐gene‐edited cloned (GEC) pigs and performed kidney transplantation from pig to rhesus monkey to evaluate the effectiveness of these GEC pigs. Results: First, 107 cell colonies were obtained through drug selection, of which seven were 4‐GE colonies. Two colonies were selected for somatic cell nuclear transfer (SCNT), resulting in seven fetuses, of which four were GGTA1 biallelic knockout. Out of these four, two fetuses had higher expression of hCD55, hTBM, and hCD39. Therefore, these two fetuses were selected for two consecutive rounds of cloning, resulting in 97 live piglets. After phenotype identification, the GGTA1 gene of these pigs was inactivated, and hCD55, hTBM, and hCD39 were expressed in cells and multiple tissues. Furthermore, the numbers of monkey IgM and IgG binding to the peripheral blood mononuclear cells (PBMCs) of the 4‐GEC pigs were markedly reduced. Moreover, 4‐GEC porcine PBMCs had greater survival rates than those from wild‐type pigs through complement‐mediated cytolysis assays. In pig‐to‐monkey kidney xenotransplantation, the kidney xenograft successfully survived for 11 days. All physiological and biochemical indicators were normal, and no hyperacute rejection or coagulation abnormalities were found after transplantation. Conclusion: These results indicate that the GTKO/hCD55/hTBM/hCD39 four‐gene modification effectively alleviates immune rejection, and the pig kidney can functionally support the recipient monkey's life.

This article explores the role of a protein called VAPYRIN (VPY) in the process of rhizobial infection in legume plants. Rhizobial infection is necessary for legumes to fix nitrogen, and the study focuses on the specific amino acid Asp394 in VPY. The research found that Asp394 is crucial for the interaction between VPY and another protein called LIN, as well as for the localization and function of VPY during infection. The study suggests that Asp394 may play a significant role in the interaction between VPY and other components of the infectosome complex, but further research is needed to fully understand its function in plant-microbe interactions.

In this work, 2D ferromagnetic M3GeTe2 (MGT, M = Ni/Fe) nanosheets with rich atomic Te vacancies (2D‐MGTv) are demonstrated as efficient OER electrocatalyst via a general mechanical exfoliation strategy. X‐ray absorption spectra (XAS) and scanning transmission electron microscope (STEM) results validate the dominant presence of metal‐O moieties and rich Te vacancies, respectively. The formed Te vacancies are active for the adsorption of OH* and O* species while the metal‐O moieties promote the O* and OOH* adsorption, contributing synergistically to the faster oxygen evolution kinetics. Consequently, 2D‐Ni3GeTe2v exhibits superior OER activity with only 370 mV overpotential to reach the current density of 100 mA cm−2 and turnover frequency (TOF) value of 101.6 s−1 at the overpotential of 200 mV in alkaline media. Furthermore, a 2D‐Ni3GeTe2v‐based anion‐exchange membrane (AEM) water electrolysis cell (1 cm2) delivers a current density of 1.02 and 1.32 A cm−2 at the voltage of 3 V feeding with 0.1 and 1 m KOH solution, respectively. The demonstrated metal‐O coordination with abundant atomic vacancies for ferromagnetic M3GeTe2 and the easily extended preparation strategy would enlighten the rational design and fabrication of other ferromagnetic materials for wider electrocatalytic applications.

The drug response phenotype is determined by a combination of genetic and environmental factors. The high clinical conversion failure rate of gene‐targeted drugs might be attributed to the lack of emphasis on environmental factors and the inherent individual variability in drug response (IVDR). Current evidence suggests that environmental variables, rather than the disease itself, are the primary determinants of both gut microbiota composition and drug metabolism. Additionally, individual differences in gut microbiota create a unique metabolic environment that influences the in vivo processes underlying drug absorption, distribution, metabolism, and excretion (ADME). Here, we discuss how gut microbiota, shaped by both genetic and environmental factors, affects the host's ADME microenvironment within a new evaluation system for drug–microbiota interactions. Furthermore, we propose a new top‐down research approach to investigate the intricate nature of drug–microbiota interactions in vivo. This approach utilizes germ‐free animal models, providing foundation for the development of a new evaluation system for drug–microbiota interactions. Highlights: Shaped by both genetic and environmental factors, gut microbiota significantly influences the host's drug absorption, distribution, metabolism, and excretion (ADME) microenvironment, highlighting the need for a new evaluation system for drug‐microbiome interactions.To investigate the intricate nature of interactions between gut microbiota and drugs in vivo, a novel top‐down research approach utilizing germ‐free animal models is proposed.

Urinary microalbumin (mALB) serves as an exceptionally sensitive indicator for the early detection of kidney damage, playing a pivotal role in identifying chronic renal failure and kidney lesions in individuals. Nevertheless, the current fluorescent methodologies for point‐of‐care (POC) diagnosis of mALB in real urine still exhibit suboptimal performance. Herein, the development and synthesis of QM‐N2, an albumin‐activated near‐infrared (NIR) aggregation‐induced emission (AIE) fluorescent probe, are presented. The strategic incorporation and positioning of quaternary ammonium salts within the quinoline‐malononitrile (QM) scaffold significantly influence solubility and luminescence characteristics. Specifically, the quaternary ammonium salt‐free variant, QM‐OH, and the quaternary ammonium salt integrated at the donor function group (DFG) site, QM‐N1, display limited solubility in aqueous solutions while demonstrating a distinct fluorescence signal. Conversely, the incorporation of quaternary ammonium salt at the conformational functional group (CFG) site in QM‐N2 imparts superior dispersibility in water and reduces the initial fluorescence. Furthermore, the integration of a well‐defined D‐π‐A structure within QM‐N2 enables itself with near‐infrared emission, which is crucial for mitigating interference from autofluorescence present in urine samples. Upon interaction with albumin, QM‐N2 forms a tight bond with the IIA site of the subdomain of human serum albumin (HSA), inducing alterations in protein configuration and constraining the intrinsic motion of fluorescent molecules. This interaction induces fluorescence, facilitating the sensitive detection of trace albumin. Ultimately, QM‐N2 is applied for POC testing of mALB using portable equipment, particularly in the diagnosis of mALB‐related diseases, notably chronic renal failure. This positioning underscores its potential as an ideal candidate for self‐health measurement at home or in community hospitals. [ABSTRACT FROM AUTHOR]

Background: Given students' lack of self‐directed learning skills and the growing concern about implementing massive online open courses (MOOCs) in K12 education, learning strategies are needed to facilitate MOOC learning. Many studies have provided different strategies for effective learning in MOOCs. However, there is still limited research to confirm whether these strategies effectively support MOOC learning when deployed by secondary schools, which are not MOOC developers. Objectives: This mixed‐method study examines the provision of different learning strategies, including a learning guide, an academic mentoring programme, a training workshop, and a reimbursement scheme, and investigates the impact of these strategies on student learning in MOOCs. Methods: The study uses two data sources: (1) surveys with 40 participants and (2) semi‐structured interviews with 12 participants. The quantitative data were analysed with descriptive statistics and Fisher's exact test, and the qualitative data were analysed with thematic analysis. Results and Conclusion: The findings indicate that MOOC learners had positive attitudes towards the overall school support, with mentoring enjoying great popularity amongst the students. In terms of the effectiveness of the school support, the mentoring programme and reimbursement scheme were more effective than the university training and learning guide. The paper discusses the implications for researchers and educators. Lay Description: What is already known about this topic: There are a large number of K12 MOOC implementations, which are (i) STEM‐related and computer science courses, and (ii) from Europe and the USA.Limited studies provided different learning strategies for MOOC learning from the perspective of K12 schools, which are not MOOC developers.There is a need to explore MOOC initiatives encompassing a wide variety of subjects, including computer science MOOCs and non‐computer science MOOCs, in regions beyond Europe and the USA.There is also a need for further scrutiny of the effectiveness of learning strategies provided by the K12 school. What this paper adds: Our study launched the first MOOC implementation in K12, encompassing several subject areas beyond computer science in the region of Asia.Our study provided different learning strategies adopted by the K12 school, and the analysis revealed that MOOC learners took positive attitudes towards overall school support with mentoring enjoying great popularity with these students.Our study examined the effectiveness of school support and identified that mentoring and reimbursement are more effective than university training and the learning guide. Implications for practitioners: The insights gained from the study enable other K12 schools and educators to implement MOOC into existing school infrastructures successfully.These strategies provided in the MOOC implementation program can be helpful in many different online learning contexts.

Conversion of carbon dioxide (CO2) to valuable chemicals and feedstocks through electrochemical reduction holds promise for achieving carbon neutrality and mitigating global warming. C2+ products are of interest due to their higher economic value. Since the CO2 to C2+ conversion process involves multiple steps, tandem catalytic strategies are commonly employed in the design of electrochemical CO2 reduction reaction (CO2RR) catalysts and systems/reactors. Among the diverse catalysts that are capable of reducing CO2 to CO, Cu stands out for more efficiently further converting CO to C2+ products. In this review, the emerging Cu‐based tandem catalysts and their impact on CO2RR performance, focusing on three positional relationships are summarized. It delves into the integration of tandem catalytic strategies into membrane electrolyzers, utilizing catalyst‐coated substrate (CCS) and catalyst‐coated membrane (CCM) technologies. Several typical examples are presented to illustrate this integration. Finally, the challenges and prospects of applying tandem strategies in the development of CO2RR catalysts/systems, as well as their device‐level implementation are indicated. [ABSTRACT FROM AUTHOR]

Formamidinium lead iodide (FAPbI3) represents an optimal absorber material in perovskite solar cells (PSCs), while the application of FAPbI3 in inverted‐structured PSCs has yet to be successful, mainly owing to its inferior film‐forming on hydrophobic or defective hole‐transporting substrates. Herein, we report a substantial improvement of FAPbI3‐based inverted PSCs, which is realized by a multifunctional amphiphilic molecular hole‐transporter, (2‐(4‐(10H‐phenothiazin‐10‐yl)phenyl)‐1‐cyanovinyl)phosphonic acid (PTZ−CPA). The phenothiazine (PTZ) based PTZ−CPA, carrying a cyanovinyl phosphonic acid (CPA) group, forms a superwetting hole‐selective underlayer that enables facile deposition of high‐quality FAPbI3 thin films. Compared to a previously established carbazole‐based hole‐selective material (2‐(3,6‐dimethoxy‐9H‐carbazol‐9‐yl)ethyl)phosphonic acid (MeO−2PACz), the crystallinity of FAPbI3 is enhanced and the electronic defects are passivated by the PTZ−CPA more effectively, resulting in remarkable increases in photoluminescence quantum yield (four‐fold) and Shockley‐Read‐Hall lifetime (eight‐fold). Moreover, the PTZ−CPA shows a larger molecular dipole moment and improved energy level alignment with FAPbI3, benefiting the interfacial hole‐collection. Consequently, FAPbI3‐based inverted PSCs achieve an unprecedented efficiency of 25.35 % under simulated air mass 1.5 (AM1.5) sunlight. The PTZ−CPA based device shows commendable long‐term stability, maintaining over 90 % of its initial efficiency after continuous operation at 40 °C for 2000 hours. [ABSTRACT FROM AUTHOR]

Background: Malformations of cortical development (MCD) are a group of congenital disorders characterized by structural abnormalities in the brain cortex. The clinical manifestations include refractory epilepsy, mental retardation, and cognitive impairment. Genetic factors play a key role in the etiology of MCD. Currently, there is no curative treatment for MCD. Phenotypes such as epilepsy and cerebral palsy cannot be observed in the fetus. Therefore, the diagnosis of MCD is typically based on fetal brain magnetic resonance imaging (MRI), ultrasound, or genetic testing. The recent advances in neuroimaging have enabled the in‐utero diagnosis of MCD using fetal ultrasound or MRI. Methods: The present study retrospectively reviewed 32 cases of fetal MCD diagnosed by ultrasound or MRI. Then, the chromosome karyotype analysis, single nucleotide polymorphism array or copy number variation sequencing, and whole‐exome sequencing (WES) findings were presented. Results: Pathogenic copy number variants (CNVs) or single‐nucleotide variants (SNVs) were detected in 22 fetuses (three pathogenic CNVs [9.4%, 3/32] and 19 SNVs [59.4%, 19/32]), corresponding to a total detection rate of 68.8% (22/32). Conclusion: The results suggest that genetic testing, especially WES, should be performed for fetal MCD, in order to evaluate the outcomes and prognosis, and predict the risk of recurrence in future pregnancies.

This study aims to explore the roles of phenylacetyl glutamine (PAGln) on myocardial infarction (MI) pathogenesis. Here, using targeted metabolomics analysis, it was found that the plasma metabolite PAGln was upregulated in coronary artery disease (CAD) patients and MI mice and could be an independent risk factor for CAD. In vivo and in vitro functional experiments revealed that PAGln pretreatment enhanced MI‐induced myocardial injury and cardiac fibrosis, as evident by the increased infarct size, cardiomyocyte death, and the upregulated expression of cardiac fibrosis markers (Col1a1 and α‐SMA). Combined with RNA‐sequencing analysis and G protein‐coupled receptor (GPCR) inhibitor, we found that the GPCR signaling activation is essential for PAGln‐mediated effects on cardiomyocyte death. Furthermore, drug affinity responsive target stability and cellular thermal shift assay demonstrated that PAGln could interact with β1‐adrenergic receptor (AR). Moreover, β1‐AR blocker treatment indeed extended the cardiac remodeling after PAGln‐enhanced MI. These results suggest that PAGln might be a potential therapeutic target for extending the cardiac remodeling window in MI patients that signals via β1‐AR. [ABSTRACT FROM AUTHOR]

Aims: This study aimed to investigate the resting‐state functional connectivity and topologic characteristics of brain networks in patients with diabetic optic neuropathy (DON). Methods: Resting‐state functional magnetic resonance imaging scans were performed on 23 patients and 41 healthy control (HC) subjects. We used independent component analysis and graph theoretical analysis to determine the topologic characteristics of the brain and as well as functional network connectivity (FNC) and topologic properties of brain networks. Results: Compared with HCs, patients with DON showed altered global characteristics. At the nodal level, the DON group had fewer nodal degrees in the thalamus and insula, and a greater number in the right rolandic operculum, right postcentral gyrus, and right superior temporal gyrus. In the internetwork comparison, DON patients showed significantly increased FNC between the left frontoparietal network (FPN‐L) and ventral attention network (VAN). Additionally, in the intranetwork comparison, connectivity between the left medial superior frontal gyrus (MSFG) of the default network (DMN) and left putamen of auditory network was decreased in the DON group. Conclusion: DON patients altered node properties and connectivity in the DMN, auditory network, FPN‐L, and VAN. These results provide evidence of the involvement of specific brain networks in the pathophysiology of DON. [ABSTRACT FROM AUTHOR]

Introduction: Long‐term spaceflight composite stress (LSCS) can cause adverse effects on human systems, including the central nervous system, which could trigger anxiety and depression. Aims: This study aimed to identify changes in hippocampus synaptic plasticity under LSCS. Methods: The present study simulated the real long‐term space station environment by conducting a 42‐day experiment that involved simulating microgravity, isolation, noise, circadian rhythm disruptions, and low pressure. The mood and behavior of the rats were assessed by behavior test. Transmission electron microscopy and patch‐clamp were used to detect the changes in synapse morphology and electrophysiology, and finally, the expression of NMDA receptor channel proteins was detected by western blotting. Results: The results showed that significant weight loss, anxiety, and depressive behaviors in rats were observed after being exposed to LSCS environment for 42 days. The synaptic structure was severely damaged, manifested as an obvious decrease in postsynaptic density thickness and synaptic interface curvature (p < 0.05; p < 0.05, respectively). Meanwhile, LTP was significantly impaired (p < 0.0001), and currents in the NMDAR channel were also significantly reduced (p < 0.0001). Further analysis found that LSCS decreased the expression of two key subtype proteins on this channel. Conclusion: These results suggested that LSCS‐induced depressive behaviors by impairing synaptic plasticity in rat hippocampus. [ABSTRACT FROM AUTHOR]

Since the inception of genetic investigations into the origin of Dryopteris species belonging to D. subg. Erythrovariae in East Asia, around 20 taxa with hybrid ancestry have been identified. Among these species, some have arisen from distant interspecific hybridization events. In this study, we describe and illustrate two newly discovered hybrids from China: Dryopteris parabissetiana sp. nov., a triploid species, and D. ×tiantangzhaiensis nothosp. nov., a diploid hybrid within Dryopteridaceae. Morphologically, D. parabissetiana exhibits similarities to D. bissetiana but can be distinguished by its ovate scales, while D. ×tiantangzhaiensis clearly displays intermediate characteristics between D. gymnophylla and D. tsoongii. Phylogenetic analyses indicate that D. tsoongii serves as their maternal parent, while D. bissetiana and D. gymnophylla are their paternal parents, respectively. Furthermore, we propose a section‐level classification for such hybrids of mixed parental sections. [ABSTRACT FROM AUTHOR]

Sodium (Na) metal anodes are promising candidates for various batteries with high energy density and high‐power density, however, the dendrite growth of Na metal is impeding their practical applications. The binary alloy Na–K is in the liquid state at room temperature with a wide composition range, which renders it inherently free from solid dendrite growth. Whereas the application of Na–K alloy is plagued by the lack of a wettable matrix to immobilize the liquid metal. Herein, a facile method is reported to introduce oxygen‐rich functional groups into carbon fiber cloth (O‐CFC), which is initially Na–K phobic yet turns into superwetting after the treatment. The superwetting behavior of the O‐CFC can be attributed to the favorable enthalpy changes as a result of the introduction of O‐rich functional groups. The superwetting property of the O‐CFC exhibits good universality, which can be extended to melting Na and K metals. By adopting the superwetting O‐CFC as a host for liquid Na–K alloy, the liquid metal can be well retained in the matrix and deliver a stable cycling for >1600 h. The concept of enthalpy‐driven wettability regulation can be enlightening for the host material design of other liquid metals and alloys. [ABSTRACT FROM AUTHOR]

Sodium dual‐ion batteries (Na‐DIBs) have attracted increasing attention due to their high operative voltages and low‐cost raw materials. However, the practical applications of Na‐DIBs are still hindered by the issues, such as low capacity and poor Coulombic efficiency, which is highly correlated with the compatibility between electrode and electrolyte but rarely investigated. Herein, fluoroethylene carbonate (FEC) is introduced into the electrolyte to regulate cation/anion solvation structure and the stability of cathode/anode‐electrolyte interphase of Na‐DIBs. The FEC modulates the environment of PF6− solvation sheath and facilitates the interaction of PF6− on graphite. In addition, the NaF‐rich interphase caused by the preferential decomposition of FEC effectively inhibits side reactions and pulverization of anodes with the electrolyte. Consequently, Sb||graphite full cells in FEC‐containing electrolyte achieve an improved capacity, cycling stability and Coulombic efficiency. This work elucidates the underlying mechanism of bifunctional FEC and provides an alternative strategy of building high‐performance dual ion batteries. [ABSTRACT FROM AUTHOR]

The development of ultra‐long room‐temperature phosphorescence (UL‐RTP) in processable amorphous organic materials is highly desirable for applications in flexible displays, anti‐counterfeiting, and bio‐imaging. However, achieving efficient UL‐RTP from amorphous materials remains a challenging task, especially with activation by visible light and a bright afterglow. Here we report a general and rational molecular‐design strategy to enable efficient visible‐light‐excited UL‐RTP by multi‐esterification of a rigid large‐plane phosphorescence core. Notably, multi‐esterification minimizes the aggregation‐induced quenching and accomplishes a ′four birds with one stone′ possibility in the generation and radiation process of UL‐RTP: i) shifting the excitation from ultraviolet light to blue‐light through enhancing the transition dipole moment of low‐lying singlet‐states, ii) facilitating the intersystem crossing process through the incorporation of lone‐pair electrons, iii) boosting the decay process of long‐lived triplet excitons resulting from a significantly increased transition dipole moment, and iv) reducing the intrinsic triplet nonradiative decay by substitution of high‐frequency vibrating hydrogen atoms. All these factors synergistically contribute to the most efficient and stable visible‐light‐stimulated UL‐RTP (lifetime up to 2.01 s and efficiency up to 35.4 % upon excitation at 450 nm) in flexible films using multi‐esterified coronene, which allows high‐tech applications in single‐component time‐delayed white light‐emitting diodes and information technology based on flashlight‐activated afterglow encryption.

2D organic–inorganic layered halide perovskites have received tremendous interest as promising materials in electronics owing to their outstanding physical properties. However, the quantum confinement effect leads to the suppression of ion migration in the out‐of‐plane direction, restricting their applications in resistive switching (RS) memories with vertical structure. Herein, the 2D layered perovskite incorporated with TiO2 nanoparticles, denoted as TiO2–PEA2PbBr4, is employed, as the functional layers to construct RS memory devices with Al/TiO2–PEA2PbBr4/ITO structure. As compared to pure 2D layered perovskite counterparts without switching behaviors, the Al/TiO2–PEA2PbBr4/ITO memories demonstrate stable bipolar RS behaviors, along with striking characteristics, including the relatively centralized set/reset voltages, a large on/off ratio (≈102), and a long retention time (104 s). In addition, the devices also present the multilevel storage capability by controlling the compliance current. Moreover, the RS behaviors are attributable to the formation/rupture of synergy bromine and oxygen vacancy conductive filaments, owing to their migration/distribution of oxygen/bromine ions under electric fields. The oxide nanoparticles incorporation route provides an effective strategy for improving RS performance in 2D layered perovskite‐based RS memories. [ABSTRACT FROM AUTHOR]

Hydroxyapatite (HA) was synthesized from chicken bone waste by calcination. Pectin was extracted from orange peels by microwave irradiation, and 1 and 3 wt % of pectin was incorporated into the HA. The resulting powders were then pressed into disk samples before being sintered at temperatures of 1050, 1150, and 1250 °C for 2 h. Various analytical techniques, including Fourier transform infrared spectroscopy, X‐ray diffraction, scanning electron microscopy, density measurement, and Vickers microhardness tests, were used to evaluate the characteristics and mechanical properties of the samples. The incorporation of pectin did not interfere with the pure phases of HA, and minimal amounts of β‐tricalcium phosphate were detected in the XRD patterns. Both ball milling and the addition of pectin effectively reduced the particle size of HA. However, the addition of pectin above 1 wt % did not contribute significantly to the densification and hardness of chicken bone‐derived HA (CHA) compared with ball‐milled CHA. Samples sintered at 1050 °C had the lowest relative density, owing to incomplete particle fusion. Increasing the sintering temperature resulted in a maximum relative density of ca. 95 % and a Vickers microhardness of 4.12 GPa for ball‐milled CHA samples sintered at 1250 °C. Sintering temperature and ball milling were observed to play a more significant role in the densification and hardness of CHA compared with the addition of pectin. [ABSTRACT FROM AUTHOR]

Objective: This study examined sex and sexual orientation differences in the context of the effects of coping strategies on relationship satisfaction. Background: The sex and sexual orientation differences on the association between coping strategies and relationship satisfaction are not yet fully understood. Method: The participants were 3,805 Belgian individuals who self‐identified as heterosexual (n = 2,024), bisexual (n = 790), or gay/lesbian (n = 991). Results: Results showed that (a) task‐oriented and emotion‐oriented coping was positively and negatively associated with relationship satisfaction, respectively; (b) social diversion–oriented coping was positively associated with relationship satisfaction only among those who identified as heterosexual, gay, or lesbian; and (c) distraction‐oriented coping was positively associated with relationship satisfaction only among those identifying as bisexual. Multiple group tests based on sex within each sexual orientation category confirm that (a) a stronger association was observed between task‐oriented coping and relationship satisfaction for bisexual men compared to bisexual women; (b) the negative association between emotion‐oriented coping and relationship satisfaction is only significant for heterosexual women, and not for bisexual women; and (c) the negative association between distraction‐oriented coping and relationship satisfaction is significant for bisexual women, but not for heterosexual women. Conclusion: This study enhances our comprehension of the variations in the utilization of coping strategies and their effect on relationship satisfaction among individuals based on their sex and sexual orientation. Implications: These findings might lead to improved interventions related to coping strategies for reducing the effect of stress in romantic relationships. [ABSTRACT FROM AUTHOR]

Genome integration‐free pig induced pluripotent stem cells (iPSCs) bring tremendous value in pre‐clinical testing of regenerative medicine, as well as conservation and exploitation of endangered or rare local pig idioplasmatic resources. However, due to a lack of appropriate culture medium, efficient induction and stable maintenance of pig iPSCs with practical value remains challenging. Here, we established an efficient induction system for exogenous gene‐independent iPSCs under chemically defined culture condition previously used for generation of stable pig pre‐gastrulation epiblast stem cells (pgEpiSCs). WNT suppression was found to play an essential role in establishment of exogenous gene‐independent iPSCs. Strikingly, stable integration‐free pig iPSCs could be established from pig somatic cells using episomal vectors in this culture condition. The iPSCs had pluripotency features and transcriptome characteristics approximating pgEpiSCs. More importantly, this induction system may be used to generate integration‐free iPSCs from elderly disabled rare local pig somatic cells and the iPSCs could be gene‐edited and used as donor cells for nuclear transfer. Our results provide novel insights into potential applications for genetic breeding of livestock species and pre‐clinical evaluation of regenerative medicine. [ABSTRACT FROM AUTHOR]

Objective: To evaluate the effect of hydroxychloroquine on conjunctival and retinal microvascular density in rheumatoid arthritis (RA) patients. Methods: Ten healthy controls, 10 RA patients who had not been treated with hydroxychloroquine, and 10 RA patients who had been treated with chloroquine for more than 5 years were recruited. Optical coherence tomography (OCTA) was used to examine the conjunctival and superficial and deep retinal microvascular density and compared the differences in microvascular density between the three groups. Results: The vascular density in RA group in superficial microvascular was significantly lower than that in control group (p < 0.001). Compared with RA group, the chloroquine group showed statistically significantly lower microvascular (p < 0.001) and deep microvascular (p = 0.018). Superficial microvascular was positively correlated with conjunctival vessel density in RA patients (r = 0.868, p = 0.0048). Conclusions: The use of chloroquine could further reduce the vascular density in the absence of statistical difference in the course of the disease. [ABSTRACT FROM AUTHOR]

Background: Ocular metastasis (OM) is a rare metastatic site of primary liver cancer (PLC). The purpose of this study was to establish a clinical predictive model of OM in PLC patients based on machine learning (ML). Methods: We retrospectively collected the clinical data of 1540 PLC patients and divided it into a training set and an internal test set in a 7:3 proportion. PLC patients were divided into OM and non‐ocular metastasis (NOM) groups, and univariate logistic regression analysis was performed between the two groups. The variables with univariate logistic analysis p < 0.05 were selected for the ML model. We constructed six ML models, which were internally verified by 10‐fold cross‐validation. The prediction performance of each ML model was evaluated by receiver operating characteristic curves (ROCs). We also constructed a web calculator based on the optimal performance ML model to personalize the risk probability for OM. Results: Six variables were selected for the ML model. The extreme gradient boost (XGB) ML model achieved the optimal differential diagnosis ability, with an area under the curve (AUC) = 0.993, accuracy = 0.992, sensitivity = 0.998, and specificity = 0.984. Based on these results, an online web calculator was constructed by using the XGB ML model to help clinicians diagnose and treat the risk probability of OM in PLC patients. Finally, the Shapley additive explanations (SHAP) library was used to obtain the six most important risk factors for OM in PLC patients: CA125, ALP, AFP, TG, CA199, and CEA. Conclusion: We used the XGB model to establish a risk prediction model of OM in PLC patients. The predictive model can help identify PLC patients with a high risk of OM, provide early and personalized diagnosis and treatment, reduce the poor prognosis of OM patients, and improve the quality of life of PLC patients.

Objective: Some studies have reported that the prognosis of total laparoscopic hysterectomy (TLH) for early‐stage cervical cancer (CC) is worse than that of open surgery. And this was associated with the use of uterine manipulator or not. Therefore, this study retrospectively analyzes the efficacy and safety of TLH without uterine manipulator combined with pelvic lymphadenectomy for early‐stage CC. Methods: Fifty‐eight patients with CC (stage IB1‐IIA1) who received radical hysterectomy from September 2019 to January 2020 were divided into no uterine manipulator (n = 26) and uterine manipulator group (n = 32). Then, clinical characteristics were collected and intraoperative/postoperative related indicators were compared. Results: Patients in the no uterine manipulator group had significantly higher operation time and blood loss than in the uterine manipulator group. Notably, there was no significant difference in hemoglobin change, blood transfusion rate, number of pelvic nodules, anal exhaust time, complications and recurrence rate between the two groups. Additionally, patients in the uterine manipulator group were prone to urinary retention (15.6%) and lymphocyst (12.5%), while the no uterine manipulator group exhibited high probability of bladder dysfunction (23.1%) and urinary retention (15.4%). Furthermore, the 1‐year disease‐free survival rate and the 1‐year overall survival rate were not significantly different between the two groups. Conclusion: There was no significant difference in the efficacy and safety of TLH with or without uterine manipulator combined with pelvic lymphadenectomy in the treatment of patients with early‐stage CC. However, the latter requires consideration of the negative effects of high operation time and blood loss. [ABSTRACT FROM AUTHOR]

Unpredictable in vivo therapeutic feedback of reactive oxygen species (ROS) efficiency is the major bottleneck of photodynamic therapy (PDT). Herein, novel PDT‐based nanotheranostics Pa–Mn&CH‐A@P are elaborately constructed for in vivo tracking biodistribution and in situ self‐reporting PDT, which innovatively unites magnetic resonance imaging (MRI) and chemiluminescence (CL) signals. Taking advantages of the versatility of lanthanide coordination chemistry and flash nanoprecipitation (FNP) technology, photosensitizers, MRI, and CL agents are unprecedently integrated within a stable and uniform nanotheranostic. Specifically, MRI signal offers detailed dose distribution of nanotheranostics with high‐spatial resolution, and CL signal timely performs in situ evaluation of ROS generation with high sensitivity. This dual‐modal MRI/CL nanotheranostic makes a breakthrough in high fidelity feedback for oral tumor, conquering the inherent unpredictable obstacles on spatially and sensitively reporting PDT.

An efficient strategy for the identification of potential nephroprotective substances in Zhu‐Ling decoction has been established with the integration of absorbed components characterization, pharmacokinetics, and activity evaluation. A qualitative method was developed to characterize the chemical constituents absorbed components in vivo of Zhu‐Ling decoction by using ultra‐performance liquid chromatography‐quadrupole‐time‐of‐flight mass spectrometry. A quantitative method was established and validated for the simultaneous determination of eight compounds in rat plasma by using ultra‐performance liquid chromatography‐triple quadruple tandem mass spectrometry. Finally, the nephroprotective activities of absorbed components with high exposure were assessed by cell survival rate, superoxide dismutase, and malondialdehyde activities in hydrogen peroxide–induced Vero cells. As a result, 111 compounds in Zhu‐Ling decoction and 36 absorbed components were identified in rat plasma and urine, and poricoic acid A, poricoic acid B, alisol A, 16‐oxo‐alisol A, and dehydro‐tumulosic acid had high exposure levels in rat plasma. Finally, poricoic acid B, poricoic acid A, 16‐oxo‐alisol A, and dehydro‐tumulosic acid showed remarkable nephroprotective activity against Vero cells damage induced by hydrogen peroxide. Besides, superoxide dismutase and malondialdehyde activities were obviously regulated in hydrogen peroxide–induced Vero cells by treatment with the four compounds mentioned above. Therefore, these four compounds were considered to be effective substances of Zhu‐Ling decoction due to their relatively high exposure in vivo and biological activity. This study provided a chemical basis for the action mechanism of Zhu‐Ling decoction in the treatment of chronic kidney diseases. [ABSTRACT FROM AUTHOR]

Cell death is a natural biological process that occurs in living organisms. Since 1963, extensive research has shed light on the occurrence, progress, and final outcome of cell death. According to different cell phenotypes, it is classified into different types, including apoptosis, pyroptosis, necroptosis, autophagy, ferroptosis, cuproptosis, and so on. However, regardless of the form of cell death, what we ultimately expect is the disappearance of abnormal cells, such as tumor cells, while normal cells survive. As a result, it is vital to investigate the details of cell death, including death triggers, potent regulators, and executioners. Although significant progress has been made in understanding molecular pathways of cell death, many aspects remain unclear because of the complex regulatory networks in cells. Among them, the phosphoinositide‐3‐kinase (PI3K)/protein kinase B(AKT) pathway is discovered to be a crucial regulator of the cell death process. AKT, as a proto‐oncogene, has become a major focus of attention in the medical community due to its role in regulating a multiplicity of cellular functions counting metabolism, immunity, proliferation, survival, transcription, and protein synthesis. Here, we explored the connection between the PI3K/AKT pathway and cell death, aiming to enhance our comprehension of the mechanism underlying this process. Such knowledge may pave the way for the subsequent development of more effective disease treatments, such as finding suitable targets for drug intervention. [ABSTRACT FROM AUTHOR]

The conventional industrial production of nitrogen‐containing fertilizers, such as urea and ammonia, relies heavily on energy‐intensive processes, accounting for approximately 3 % of global annual CO2 emissions. Herein, we report a sustainable electrocatalytic approach that realizes direct and selective synthesis of urea and ammonia from co‐reduction of CO2 and nitrates under ambient conditions. With the assistance of a copper (Cu)‐based salphen organic catalyst, outstanding urea (3.64 mg h−1 mgcat−1) and ammonia (9.73 mg h−1 mgcat−1) yield rates are achieved, in addition to a remarkable Faradaic efficiency of 57.9±3 % for the former. This work proposes an appealing sustainable route to converting greenhouse gas and waste nitrates by renewable energies into value‐added fertilizers. [ABSTRACT FROM AUTHOR]

Aggregation induced emission (AIE) photosensitizers have attracted great attention due to their good performance in photodynamic therapy (PDT). However, the therapeutic effect of AIE photosensitizer is often highly dependent on the biological microenvironment because it is difficult to produce type I and type II reactive oxygen species (ROS) simultaneously. Herein, an electron‐rich anion‐π+ AIEgen Pys‐QM‐TT is reported, which is capable of highly generating type I and type II ROS and realizing near‐infrared fluorescence imaging synchronously. In the rational design of AIE photosensitizer, the strong electron‐donating triphenylamine unit, π‐bridge thiophene and electron‐withdrawing pyridinium salt unit can enhance the D–π–A behavior, thereby improving the intramolecular charge transfer effect and extending the wavelength. Meanwhile, the powerful D–π–A effect is supposed to reduce ∆ES‐T and promote the intersystem crossing processes, thus increasing the generation of ROS. In addition, the negatively charged anion in pyridinium salt group provides an electron‐rich environment for the excited photosensitizer, so as to promote electron transfer to generate type I ROS. Therefore, Pys‐QM‐TT can not only generate type I and type II ROS simultaneously with weak environmental dependence, but also effectively inhibit bacterial infections and ablate tumor tissue by promoting tumor cell apoptosis, inhibiting tumor cell proliferation and anti‐angiogenesis.

Background: Myopia has become a worldwide problem that endangers public health and adds a serious socioeconomic burden. Current research has focused on the pathogenesis and manifestations of pathological myopia (PM). However, few studies have been conducted on the spontaneous activity of the patient's brain. Purpose: To study the potential brain network activity in patients with PM by the degree centrality (DC) method. Materials and Methods: This experiment included 15 PM patients and 15 healthy controls (HCs). Every participant experienced a resting‐state functional magnetic resonance imaging (rs‐fMRI) scan. Receiver operating characteristic (ROC) curve analysis was used to distinguish between PM patients and HCs. Correlation analysis was used to explore the relationships between mean DC values and clinical performance in different brain regions. Results: It showed that patients with PM had lower DC values in the right fusiform gyrus (FR) and right cingulate (CAR). The ROC curve was used to indicate the accuracy of the correlation. It showed that in PM group, left best corrected visual acuity (BCVA‐L) and right best corrected visual acuity (BCVA‐R) were negatively correlated with the DC value of FR. Conclusion: The occurrence of PM is mainly related to the abnormal activity of the fusiform and cingulum. DC value might be used as a biological marker of abnormal brain activity in PM patients.

Room temperature sodium sulfur (RT Na‐S) batteries with high theoretical energy density and low cost have recently gained extensive attention for potential large‐scale energy storage applications. However, the shuttle effect of sodium polysulfides is still the main challenge that leads to poor cycling stability, which hinders the practical application of RT Na‐S batteries. Herein, a multifunctional hybrid MXene interlayer is designed to stabilize the cycling performance of RT Na‐S batteries. The hybrid MXene interlayer comprises a large‐sized Ti3C2Tx nanosheets inner layer followed by a small‐sized Mo2Ti2C3Tx nanoflake outer layer on the surface of the glass fiber (GF) separator. The large‐sized Ti3C2Tx nanosheet inner layer provides an effective physical block and chemical confinement for the soluble polysulfides. The small‐sized Mo2Ti2C3Tx outer layer offers an excellent polysulfide trapping capability and accelerates the reaction kinetics of polysulfide conversion, due to its superior electronic conductivity, large specific surface area, and Mo‐rich catalytic surfaces. As a result, RT Na‐S batteries with this hybrid MXene interlayer modified glass fiber separator deliver a stable cycling performance over 200 cycles at 1 C with an enhanced capacity retention of 71%. This unique structure design provides a novel strategy to develop 2D material‐based functional interlayer for high‐performance metal‐sulfur batteries. [ABSTRACT FROM AUTHOR]

The challenges of voltage decay and irreversible oxygen release for lithium‐rich layered oxide cathode materials have hindered their commercial application despite their high energy density and low cost. Herein, a facile post‐annealing strategy is developed to pre‐introduce oxygen vacancies (OVs) into Li1.2Mn0.457Ni0.229Co0.114O2 cathode materials. The induced OVs modify the local Mn coordination environments, enhance structural stability, and suppress oxygen release. The modified cathode exhibits a discharge capacity of 224.1 mAh g−1 at 0.1 C after 100 cycles with 97.7 % capacity retention. Even at 2 C, excellent capacity retention of 93.3 % after 300 cycles can be achieved. In situ and ex situ X‐ray diffraction are used to elucidate the reaction mechanisms and crystal structure during cycling tests. Ex situ X‐ray photoelectron spectroscopy confirmed the suppressed oxygen release, enhanced oxygen vacancies and reduced cathode‐electrolyte interfacial layer after cycling for the post‐annealed cathode. Our results show that the presence of oxygen vacancies through thermal expansion diminishes the phase transitions in cathode materials during the heating process. These findings contribute to developing next‐generation Li‐ion batteries (LIBs) by oxygen vacancy engineering for new cathode materials with improved electrochemical performances.

The topological system of lakes and streams is the basis for deriving a multitude of patterns and processes in hydrology, geomorphology and ecology. Flow direction is key to constructing a lake‐stream topological system. However, lakes and streams are important hydrological objects that should be considered since they are linked during the process of material and energy transportation. Therefore, a flow direction algorithm that can clearly express the topological relationship of lakes and streams, was proposed here. Lakes and streams were taken as the hydrological objects in stream networks and coupled into a flow direction algorithm. A topological system was established based on the proposed algorithms. Six areas on the Tibetan Plateau were chosen as sample areas with the MERIT digital elevation model (DEM) as the DEM data source. Streams derived from flow direction data in the HydroSHEDS data set (HYDROSTREAMS) and MERIT hydro data set (MERITSTREAMS), as well as streams derived from flow direction results of the D‐infinity algorithm and priority‐flood algorithm were compared with streams derived from the proposed algorithm. The topological relationship between streams and lakes was clearly expressed by the proposed algorithm. In lake areas, the proposed algorithm showed better performance, and no parallel streams were found. In nonlake areas, the stream networks derived from these algorithms were stable. The proposed algorithm offers an opportunity to treat lakes and streams differently during simulation, thus adding to the authenticity of the simulation. Key Points: A novel flow direction algorithm considering the characteristics of lake‐stream is proposed to construct a lake‐stream topological systemThe proposed flow direction model exhibits good robustness, considering the errors in lake areas in digital elevation modelsThe constructed lake‐stream topological system can be applied in both endorheic and exorheic basins worldwide [ABSTRACT FROM AUTHOR]
