    Abstract: Herein, we report a convenient route to fabricate pseudohexagonal phase niobium pentoxide (TT‐Nb 2 O 5 ) nanopillars via combination of laser ablation in liquids (LAL) and hydrothermal treatment without using any organic surfactants or stabilizers. The morphology and structure of the as‐synthesized samples are investigated through scanning and transmission electron microscopy, X‐ray diffraction, and X‐ray photoelectron spectroscopy. Such nanopillars exhibit excellent lithium storage properties, including high reversible capacity, good rate capability, and excellent cycle stability (81% capacity retention after 1000 cycles) at a rate of 5 C in the potential range of 1.0 to 3.0 V, which is higher than other previously reported Nb 2 O 5 ‐based electrode. The synergistic effects from the nanopillar morphology, high electronic conductivity and stable structure promise potential applications in high‐security and high‐rate capability Li‐ion batteries.

    Abstract: Pathogenic bacteria that adhere on the surface of textiles, especially healthcare workers’ uniforms, have brought severe problems, including nosocomial infection and other infectious diseases. Here, antibacterial textiles are fabricated by in situ growing oxygen vacancies (OVs) BiOBr on the surface of Ti 3 C 2 nanosheets followed by in situ polymerization of polypyrrole (ppy). The formed Schottky heterojunction containing OVs of Ti 3 C 2 /BiOBr effectively enhance the transfer and separation of photogenerated carriers, inhibit the recombination, and decrease the band gap by introducing defect level, which significantly improve the photocatalytic activity, leading to higher reactive oxygen species (ROS) under light irradiation. Therefore, the antibacterial efficacy of textiles reaches up to 98.64% against Staphylococcus aureus and 99.89% against Escherichia coli with the assistance of hyperthermia under light irradiation for 15 min. This work provides insights for designing photo‐excited antibacterial textiles by interfacial construction based on Schottky junctions and OVs in the incorporated nanomaterials.

    Abstract: A hexanuclear Nd (III) complex {[Nd 6 (HL) 2 L 2 X 2 (NO 3 ) 8 (EtOH) 6 ]·(EtOH)(H 2 O) 3 } (H 2 L = 2,3‐dihydroxybenzaldehyde‐4‐aminoantipyrine; H 2 X = 2,3‐dihydroxy benzaldehyde) has been designed, synthesized, and evaluated for antitumor and antifungal activity. Single‐crystal X‐ray diffraction analysis indicates Nd (III) complex has a trinuclear cluster structure, which further forms a hexanuclear monomer through two bridging ligands L 2− . There are π–π interactions and a lot of intramolecular hydrogen bonds between monomers. Antitumor activity of Nd (III) complex against human hepatocellular carcinoma SMMC‐7721 cells has been studied by 3‐(4,5‐dimethyl‐2‐thiazolyl)‐2,5‐diphenyltetrazolium bromide (MTT) assay and morphology observation. The IC 50 value of Nd (III) complex ranges from 4.02 to 4.85 μM, much smaller than that of clinical drug (gemcitabin) and free ligand (H 2 L), which is consistent with its high inhibition rate of 90%. Inhibitory zone of 26 mm reveals the significant antifungal activity of Nd (III) complex against Candida albicans .

    Abstract: Sprouting angiogenesis is a major form of neovascularization of tissues suffering from hypoxia and other related stress. Endothelial cells (ECs) undergo proliferation, differentiation, programmed death, and migration during angiogenic sprouting, but the underlying molecular mechanisms regulating ECs in angiogenesis have been incompletely elucidated. Here we report that the transmembrane protein 215 (TMEM215) is involved in angiogenesis by regulating EC survival. The murine TMEM215 gene, which possesses two transcriptional starting sites as determined by 5′‐rapid amplification of complementary DNA (cDNA) ends (RACE), encodes a two‐pass TMEM. The TMEM215 transcripts were detected in ECs in addition to other tissues by quantitative reverse transcription‐polymerase chain reaction. Immunofluorescence showed that TMEM215 was expressed in the vasculature in retina, liver, and tumor, and colocalized with EC markers. We show that knockdown of TMEM215 in ECs induced strong cell death of ECs in vitro without affecting cell proliferation and migration, suggesting that TMEM215 was required for EC survival. Downregulation of TMEM215 expression compromised lumen formation and sprouting capacities of ECs in vitro. Moreover, intravitreous injection of TMEM215 small interfering RNA resulted in delayed and abnormal development of retinal vasculature with poor perfusion. These results identified TMEM215 as a novel molecule involved in angiogenesis by regulating the survival of ECs.

    Abstract: Semiconducting 2D transition metal dichalcogenides (2D TMDs) with tunable electronic properties are a fundamental prerequisite for the development of next generation advanced electronic/optoelectronic devices. However, controllable and quasi‐continuous tuning carrier polarity of monolayered MoS 2 ranging from intrinsic n ‐type to p ‐type via ambipolarity still remains a challenge. Herein, quasi‐continuous tailoring of carrier polarity of monolayered MoS 2 through substitutional doping of molybdenum (Mo) with vanadium (V) atoms is presented. Atomic distribution in real space characterized by spherical aberration‐corrected scanning transmission electron microscopy (Cs‐STEM) reveals that the V atoms randomly substitute Mo in monolayered MoS 2 , and its doping concentration can be tuned in a wide range from 0.7 to ≈10 at.%. Electrical measurements confirm that the carrier polarity of the monolayered MoS 2 can be tuned from intrinsic n ‐type to p ‐type via ambipolarity depending on the V doping degree, consistent with the density functional theory calculations. Moreover, this doping strategy is demonstrated to extend to other monolayered 2D TMDs by using MoSe 2 as a model material, owing to a good universality.

    Abstract: Quinazoline has been reported to exhibit multiple bioactivities. The aim of this study was to discover new quinazoline derivatives with preventive effect on lipopolysaccharide‐induced acute lung injury via anti‐inflammatory actions. Thirty‐three 4‐amino quinazolin derivatives were synthesized and screened for anti‐inflammatory activities in lipopolysaccharide‐induced macrophages. The most potent four compounds, 6h, 6m, 6p , and 6q , were shown dose‐dependent inhibition against lipopolysaccharide‐induced TNF‐α and IL‐6 release. Then, the preliminary structure–activity relationship and quantitative structure–activity relationship analyses were conducted. To further determine the effects of quinazolines on acute lung injury treatment, lipopolysaccharide‐induced acute lung injury model was employed. Male Sprague Dawley rats were pretreated with 6m or 6q before instillation of lipopolysaccharide. The results showed that 6m and 6q, especially 6q , obviously alleviated lung histopathological changes, inflammatory cells infiltration, and cytokines mRNA expression initiated by lipopolysaccharide. Taken together, this work suggests that 6m and 6q suppressed the lipopolysaccharide‐induced acute lung injury through inhibition of the inflammatory response in vivo and in vitro , indicating that quinazolines might serve as potential agents for the treatment of acute lung injury and deserve the continuing drug development and research.

    Abstract: The objective of this study is to evaluate the long‐term effects of preeclampsia (PE) on metabolic and biochemical outcomes in offspring. We searched PubMed‐Medline, Web of Science, and EMBASE from inception to June 2021 for randomized clinical trials, cohort, and case–control studies. Two researchers independently extracted data according to the Preferred Reporting Items for Systematic Reviews and Meta‐analyses (PRISMA) guidelines and assessed possible bias. Rate ratios (RRs) or weighted mean differences (WMDs) were estimated using fixed‐effects model or random‐effects model if the heterogeneity was high. PE increased offspring risk of obesity (RR 1.45, 95% confident interval [CI] 1.19–1.78) with a mean weighted age of 9.1 years, and a higher body mass index from 10 years of age (WMD 0.46, 95% CI 0.08–0.83). PE offspring were associated with a higher mean arterial pressure (WMD 1.33, 95% CI 0.42–2.24), systolic blood pressure (WMD 1.93, 95% CI 1.48–2.37), and diastolic blood pressure (WMD 1.13, 95% CI 0.80–1.47) in puberty. However, we uncovered no association between PE and offspring levels of total cholesterol, triglycerides, high‐density lipoprotein, low‐density lipoprotein, glucose, and insulin in blood with puberty, nor was there an increase in the risk of type 1 diabetes mellitus in PE offspring under 15 years of age (RR 1.07, 95% CI 0.88–1.32). However, PE might be associated with central obesity, hypertension, and type 2 diabetes mellitus of offspring in later life. Offspring of mothers with PE exhibited an increased risk of obesity in childhood and a higher body mass index and blood pressure in puberty, but there were no differences in blood lipids or glucose metabolism in puberty compared to non‐PE offspring. PE might be associated with a higher risk for central obesity, hypertension, and type 2 diabetes mellitus of offspring in later life.

    Abstract: As the "powerhouse" of cells, mitochondrion is the main site of cellular aerobic respiration and plays a vital role in performing many important cellular functions. The consequence of mitochondrial dysfunction could lead to a wide range of disorders and diseases. Traditional mitochondria‐related cytobiology methods always require the isolation of organelles for biological components, followed by structural analysis and quantitative analysis. In this study, we tried to assess the feasibility and reliability of the isolation‐based method and the in situ approach from the spectral fingerprint characters. Surface‐enhanced Raman scattering spectroscopy (SERS) was employed to investigate the molecular information of mitochondria from cancer cells (HepG2 and MCF‐7 cells) in situ with the assistant of mitochondrion‐targeting nanoprobes, which was compared with the isolation‐based ex situ method. The results display two methods, which show high consistency in the spectral profiles of mitochondrion, proving the feasibility of both in bioanalysis. Abundant molecular information such as protein and DNA is disclosed, and protein is one of the main components. From spectral comparison between two cancer cells, differences in protein content are observed. We believe that this comparative study will provide a valuable and recommended reference for the selection of analytical methods for different study purposes.

    Abstract: The impacts of the current COVID‐19 pandemic on maternal and foetal health are enormous and of serious concern. However, the influence of SARS‐CoV‐2 infection at early‐to‐mid gestation on maternal and foetal health remains unclear. Materials and methods Here, we report the follow‐up study of a pregnant woman of her whole infective course of SARS‐CoV‐2, from asymptomatic infection at gestational week 20 to mild and then severe illness state, and finally cured at Week 24. Following caesarean section due to incomplete uterine rupture at Week 28, histological examinations on the placenta and foetal tissues as well as single‐cell RNA sequencing (scRNA‐seq) for the placenta were performed. Results Compared with the gestational age‐matched control placentas, the placenta from this COVID‐19 case exhibited more syncytial knots and lowered expression of syncytiotrophoblast‐related genes. The scRNA‐seq analysis demonstrated impaired trophoblast differentiation, activation of antiviral and inflammatory CD8 T cells, as well as the tight association of increased inflammatory responses in the placenta with complement over‐activation in macrophages. In addition, levels of several inflammatory factors increased in the placenta and foetal blood. Conclusion These findings illustrate a systematic cellular and molecular signature of placental insufficiency and immune activation at the maternal–foetal interface that may be attributed to SARS‐CoV‐2 infection at the midgestation stage, which highly suggests the extensive care for maternal and foetal outcomes in pregnant women suffering from COVID‐19.

    Abstract: Alternative splicing ( AS ) is a crucial regulatory mechanism in eukaryotes, which acts by greatly increasing transcriptome diversity. The extent and complexity of AS has been revealed in model plants using high‐throughput next‐generation sequencing. However, this technique is less effective in accurately identifying transcript isoforms in polyploid species because of the high sequence similarity between coexisting subgenomes. Here we characterize AS in the polyploid species cotton. Using Pacific Biosciences single‐molecule long‐read isoform sequencing (Iso‐Seq), we developed an integrated pipeline for Iso‐Seq transcriptome data analysis ( https://github.com/Nextomics/pipeline-for-isoseq ). We identified 176 849 full‐length transcript isoforms from 44 968 gene models and updated gene annotation. These data led us to identify 15 102 fibre‐specific AS events and estimate that c . 51.4% of homoeologous genes produce divergent isoforms in each subgenome. We reveal that AS allows differential regulation of the same gene by mi RNA s at the isoform level. We also show that nucleosome occupancy and DNA methylation play a role in defining exons at the chromatin level. This study provides new insights into the complexity and regulation of AS , and will enhance our understanding of AS in polyploid species. Our methodology for Iso‐Seq data analysis will be a useful reference for the study of AS in other species.
