Myocardial ferroptosis may exacerbate the progression of atrial fibrillation through isolevuglandins.

Atrial fibrillation (AF) poses a serious health threat to human health and causes various adverse effects. It is currently the most common type of arrhythmia in adults. Long-term AF induces a series of heart-remodeling events, including mainly cardiac structural remodeling and electrical remodeling, which further exacerbates AF.

Prmt5 is essential for intestinal stem cell maintenance and homeostasis.

Intestinal homeostasis relies on the continuous renewal of intestinal stem cells (ISCs), which could be epigenetically regulated. While protein arginine methyltransferase 5 (Prmt5) is known to play a key role in multiple organs as an epigenetic modifier, its specific function in maintaining intestinal homeostasis remains to be elucidated. Here, we show that Prmt5 is highly expressed in mouse crypts.

Global trends and projections of high BMI burden and its independent impact on atrial fibrillation and flutter.

Boron controls apical dominance in Pea (Pisum sativum) via promoting polar auxin transport.

Plant architecture and subsequent productivity are determined by the shoot apical dominance, which is disturbed by the deficiency of boron, one of the essential trace elements for plant growth and reproduction. However, the mechanism by which B controls shoot apical dominance or axillary bud outgrows under B deficiency is still unclear. This work aimed to investigate the mechanistic basis of this process, with focus on the interaction between B and polar auxin transport.

Genetic Characterization, Transmission Pattern and Health Risk Analysis of Intestinal Colonization ESBL-Producing in Vegetable Farming Population.

The surging prevalence rates of ESBL-producing (ESBL-Ec) pose a serious threat to public health. To date, most research on drug-resistant bacteria and genes has focused on livestock and poultry breeding areas, hospital clinical areas, natural water environments, and wastewater treatment plants. However, few studies have been conducted on drug-resistant bacteria in vegetable cultivation.

This research is aimed at unravelling the intricate relationship between transient receptor potential vanilloid 6 (TRPV6), protein kinase A (PKA), uncoupling protein 2 (UCP2), and atherosclerosis. By shedding light on the role of the TRPV6/PKA/UCP2 pathway in inhibiting inflammatory response and cell apoptosis in coronary atherosclerotic plaques, this study provides valuable insights into potential therapeutic targets for treating coronary artery disease (CAD). We established animal and cell models of atherosclerosis.

Conductive polyacrylamide/pullulan/ammonium sulfate hydrogels with high toughness, low-hysteresis and tissue-like modulus as flexible strain sensors.

Conductive hydrogels have great potential for applications in flexible wearable sensors due to the combination of biocompatibility, mechanical flexibility and electrical conductivity.

In the present study, we prepared a tough and conductive polyacrylamide/pullulan/ammonium sulfate hydrogel with a semi-interpenetrating network.

In/Outside Catalytic Sites of the Pore Walls in One-Dimensional Covalent Organic Frameworks for Oxygen Reduction Reaction.

Pore channels play a decisive role in mass transport in catalytic systems. However, the influences of the location of catalytic sites inside or outside of the pore walls on the performance were still under-explored due, because it is difficult to construct sites anchored in or outside of pore walls. Herein, one-dimensional covalent organic frameworks with precisely anchored active sites were used to explore the effects of channels on a typical oxygen reduction reaction (ORR) catalysis.

In this study, we examined the effect of IAA treatment on the softening of postharvest kiwifruit.

Three-Dimensional Covalent Organic Framework with Dense Lithiophilic Sites as Protective Layer to Enable High-Performance Lithium Metal Battery.

Lithium (Li) metal batteries with remarkable energy densities are restrained by short lifetime and low Coulombic efficiency (CE), resulting from the accumulative Li dendrites and dead Li during cycling. Here, we prepared a new three-dimensional (3D) covalent organic framework (COF) with dense lithiophilic sites (heteoatom weight contents of 32.32 wt %) as an anodic protective layer of Li metal batteries.

Steady existence of Escherichia coli co-resistant to carbapenem and colistin in an animal breeding area even after the colistin forbidden.

Carbapenem- and colistin-resistant Escherichia coli (CCREC) cause high mortality rates and health costs, and have become serious health concerns. Total 1764 samples were collected from 60 animal farms in 2019 and 2021, including worker and animal faeces, wastewater, well water, air, vegetables, human hands, object surfaces, throat swabs, soil, and flies to investigate the prevalence and potential transmission pathways of CCREC. Eleven CCREC were detected: 9 (5 in 2019 and 4 in 2021) from 5 worker faeces, 3 animal faeces, 1 wastewater, and 2 from 1 flies sample.

EjWRKY6 Is Involved in the ABA-Induced Carotenoid Biosynthesis in Loquat Fruit during Ripening.

The yellow-fleshed loquat is abundant in carotenoids, which determine the fruit's color, provide vitamin A, and offer anti-inflammatory and anti-cancer health benefits. In this research, the impact of abscisic acid (ABA), a plant hormone, on carotenoid metabolism and flesh pigmentation in ripening loquat fruits was determined. Results revealed that ABA treatment enhanced the overall content of carotenoids in loquat fruit, including major components like -cryptoxanthin, lutein, and -carotene, linked to the upregulation of most genes in the carotenoid biosynthesis pathway.

Nitrogen-Site Engineering in Covalent Organic Frameworks for HO Photogeneration via Dual Channels of Indirect Two-Electron O Reduction.

Photocatalytic HO production is a green and sustainable route, but far from meeting the increasing demands of industrialization due to the rapid recombination of the photogenerated charge carriers and the sluggish reaction kinetics. Effective strategies for precisely regulating the photogenerated carrier behavior and catalytic activity to construct high-performance photocatalysts are urgently needed. Herein, a nitrogen-site engineering strategy, implying elaborately tuning the species and densities of nitrogen atoms, is applied for HO photogeneration performance regulation.

IDO1 Inhibitor RY103 Suppresses Trp-GCN2-Mediated Angiogenesis and Counters Immunosuppression in Glioblastoma.

Glioma is characterized by strong immunosuppression and excessive angiogenesis. Based on existing reports, it can be speculated that the resistance to anti-angiogenic drug vascular endothelial growth factor A (VEGFA) antibody correlates to the induction of novel immune checkpoint indoleamine 2,3-dioxygenase 1 (IDO1), while IDO1 has also been suggested to be related to tumor angiogenesis. Herein, we aim to clarify the potential role of IDO1 in glioma angiogenesis and the mechanism behind it.

Melatonin extends shelf life in postharvest okra via delaying fruit softening and reducing weight loss.

Background: Melatonin, a hormone present in animals and some plants, has garnered attention for its potential in preserving harvested produce. Softening due to changes in cell wall composition and wilting caused by weight loss are the major reasons for the loss of commercial value in postharvest okra. This study aimed to evaluate the impact of melatonin on the softening and weight loss of postharvest okra.

Synergistic Linker and Linkage of Covalent Organic Frameworks for Enhancing Gold Capture.

The tunable pore walls and skeletons render covalent organic frameworks (COFs) as promising absorbents for gold (Au) ion. However, most of these COFs suffered from low surface areas hindering binding sites exposed and weak binding interaction resulting in sluggish kinetic performance. In this study, COFs have been constructed with synergistic linker and linkage for high-efficiency Au capture.

Creating Asymmetric Fe-NC-N Sites in Single-Atom Catalysts Boosts Catalytic Performance for Oxygen Reduction Reaction.

Fine tuning of the metal site coordination environment of a single-atom catalyst (SAC) to boost its catalytic activity for oxygen reduction reaction (ORR) is of significance but challenging. Herein, we report a new SAC bearing Fe-NC-N sites with asymmetric in-plane coordinated Fe-NC and axial coordinated N atom for ORR, which was obtained by pyrolysis of an iron isoporphyrin on polyvinylimidazole (PVI) coated carbon black. The C@PVI-(NCTPP)Fe-800 catalyst exhibited significantly improved ORR activity ( = 0.
