A feeding-induced myokine modulates glucose homeostasis.

Nat Metab

January 2025

State Key Laboratory of Membrane Biology, MOE Key Laboratory of Bioinformatics, Tsinghua-Peking Center for Life Sciences, School of Life Sciences, Tsinghua University, Beijing, China.

Maintaining blood glucose homeostasis during fasting and feeding is crucial for the prevention of dysregulation that can lead to either hypo- or hyperglycaemia. Here we identified feimin, encoded by a gene with a previously unknown function (B230219D22Rik in mice, C5orf24 in humans), as a key modulator of glucose homeostasis. Feimin is secreted from skeletal muscle during feeding and binds to its receptor, receptor protein tyrosine kinase Mer (MERTK), promoting glucose uptake and inhibiting glucose production by activation of AKT.

Mechanical Reversal in the Catalytic Capability of Monolayer Transition Metal Dichalcogenides for Hydrogen Evolution Reaction: An Explicit First-Principles Study.

ACS Appl Mater Interfaces

January 2025

State Key Laboratory of Mechanics and Control for Aerospace Structures, MOE Key Laboratory for Intelligent Nano Materials and Devices, College of Aerospace Engineering, Nanjing University of Aeronautics and Astronautics, Nanjing 210016, China.

Pristine transition metal dichalcogenide (TMD) monolayers are generally regarded as exhibiting low chemical reactivity due to their inert surfaces. Our extensive first-principles calculations, which incorporate an explicit solvation model, reveal that the catalytic performance of pristine TMD MX (where M = Mo or W, and X = S, Se or Te) monolayers for hydrogen evolution reaction can be significantly altered and enhanced through mechanically bending deformation. For a WTe monolayer, its hydrogen adsorption Gibbs free energy decreases to 0.

TCSRNet: a lightweight tobacco leaf curing stage recognition network model.

Front Plant Sci

December 2024

Jiangxi Branch of China National Tobacco Corporation, Nanchang, China.

Due to the constraints of the tobacco leaf curing environment and computational resources, current image classification models struggle to balance recognition accuracy and computational efficiency, making practical deployment challenging. To address this issue, this study proposes the development of a lightweight classification network model for recognizing tobacco leaf curing stages (TCSRNet). Firstly, the model utilizes an Inception structure with parallel convolutional branches to capture features at different receptive fields, thereby better adapting to the appearance variations of tobacco leaves at different curing stages.

Vascular cambium is the continuation of meristem activity at the top of plants, which promotes lateral growth of plants. The vascular cambium evolved as an adaptation for secondary growth, initially in early seed plants, and became more refined in the evolution of gymnosperms and angiosperms. In angiosperms, it is crucial for plant growth and wood formation.

Article Synopsis
  • The study investigates how gut microbial metabolites (GMM), specifically phenylacetylglutamine (PAGln), are linked to cardiovascular diseases (CVD) in people with alcohol use disorder.
  • In experiments with mice, researchers found that chronic alcohol consumption led to changes in gut microbes and increased PAGln levels, which were associated with cardiovascular issues.
  • PAGln was shown to cause heart and blood vessel problems independent of alcohol, indicating that it plays a significant role in the development of CVD related to alcohol consumption.

Determining the Optimal Age for Extracranial-Intracranial Bypass Surgery: A Post Hoc Analysis of the CMOSS Randomized Trial.

Stroke

February 2025

Department of Neurosurgery and Interventional Neuroradiology (L.J.), Xuanwu Hospital, China International Neuroscience Institute, Capital Medical University, National Center for Neurological Disorders, Beijing, China.

A Dual-Functional Sulfur-Rich Copolymers for Stable Anchoring and Enhanced Conversion of Polysulfide in Lithium-Sulfur Batteries.

Chemistry

December 2024

State Key Laboratory of Fine Chemicals, School of Chemical Engineering, Dalian University of Technology, Dalian, Liaoning, 116024, China.

Sulfur-rich copolymers have gained a great deal of attention as promising cathode materials in Li-S batteries due to their low cost and naturally uniform sulfur dispersion. However, the poor electrical conductivity and shuttle effect cause rapid capacity decay and low sulfur utilization especially under high sulfur loading and low electrolyte/sulfur ratio. Herein, the FeS/C dispersed and Se-containing sulfur-rich copolymer (FSP) was synthesized by one-pot reaction of ferrocene, trithiocyanuric acid with SeS.

Approaches that add value to biomass through the use of photoreforming reactions offer great opportunities for the efficient use of renewable resources. Here, we constructed a novel zinc cadmium sulphide/molybdenum dioxide-molybdenum carbide-carbon (ZnCdS-y/MoO-MoC-C) heterojunction which was applied to photoreforming of biomass-based monosaccharides for hydrogen and lactic acid production. Bandgap engineering effectively modulated the redox capacity of ZnCdS-y and exposed more (101) crystalline surfaces, which improved the lactic acid selectivity.

Decades of research have established that mammalian transcription factors (TFs) bind to each gene's regulatory regions and cooperatively control tissue specificity, timing, and intensity of gene transcription. Mapping the combination of TF binding sites genome wide is critically important for understanding functional genomics. Here, we report a technique to measure TFs' binding sites on the human genome with a near single-base resolution by footprinting with deaminase (FOODIE) on a single-molecule and single-cell basis.

Robust Ferroelectricity in Nonstoichiometric 2D AgCrS via Chemical Vapor Deposition.

Small

December 2024

Key Laboratory of Photochemical Conversion and Optoelectronic Materials, Technical Institute of Physics and Chemistry, Chinese Academy of Sciences, Beijing, 100190, China.

Ferroelectricity in two-dimensional (2D) materials at room temperature has attracted significant interest due to their substantial potential for applications in non-volatile memory, nanoelectronics, and optoelectronics. The intrinsic tendency of 2D materials toward nonstoichiometry results in atomic configurations that differ from those of their stoichiometric counterparts, thereby giving rise to potential ferroelectric polarization properties. However, reports on the emergence of room temperature ferroelectric effects in nonstoichiometric 2D materials remain limited.

December 2024

Key Laboratory of Advanced Functional Materials of Education Ministry of China, Beijing Key Laboratory of Microstructure and Properties of Solids, College of Material Science and Engineering, Beijing University of Technology, Beijing 100124, China.

WS is an attractive anode in alkali metal ion batteries (AMIBs) due to its 2D-layered structure and high theoretical capacity. However, the shuttle effect of sulfur and the spontaneous growth of W nanoparticles are key issues that limit the alkali-ion accommodation ability. Now, it is still a great challenge to achieve in situ control of the microstructure evolution paths in enclosed batteries for extending the cycling reversibility/lifespan.
