Cellular Senescence in the Regenerative Niche Hampers Skeletal Muscle Repair.

With the growing interest in skeletal muscle diseases, understanding the processes, factors, and treatments associated with muscle regeneration is crucial. Skeletal muscle regeneration is a complex process that largely depends on the niche composed of cell populations, such as satellite cells, and their microenvironment. Cellular senescence is associated with various physiological processes and age-related diseases and plays a significant role in the muscle regeneration niche.

A Novel Coating-Extrusion Method Enabled, High Energy, Power Density, and Scalable Production in Monolithically Integrated Energy Storage Fibers.

The rise of wearable electronics demands flexible energy storage solutions like flexible fiber energy storage devices (FESDs), known for their flexibility and portability. However, it remains difficult for existing fabrication methods (typically, finite-coating, thermal-drawing, and solution-extrusion) to simultaneously achieve desirable electrochemical performances and fast production of FESDs. Here, a new scalable coating-extrusion method is developed, utilizing a novel extruded spinneret with tapered apertures to create dual pressure zones.

Negative Enthalpy Doping Stabilizes P2-Type Oxides Cathode for High-Performance Sodium-Ion Batteries.

P2-type NaNiMnO (NNMO) as cathode material for sodium-ion batteries (SIBs) largely suffers from continuous accumulation of local stress caused by destructive structural evolution and irreversible oxygen loss upon cycling, leading to rapid capacity degradation. Herein, a strategy of negative enthalpy doping (NED), wherein transition metal (TM) sites are substituted with 0.01 mol each Sn, Sb, Cu, Ti, Mg, and Zn to increase the stability of the TM layers, is proposed.

Danshensu Derivatives: A Series of Promising Drugs With Protective Effects Against Cardiocerebrovascular Diseases and Cancers.

Salvia miltiorrhiza (Danshen in Chinese) is a traditional medicinal plant with an extensive range of cardiocerebrovascular protective effects widely used in China and other Asian countries. Danshensu (DSS) is the most important water-soluble component of Danshen and has significant antioxidant, anti-inflammatory, antiplatelet aggregation, antitumor, and other pharmacological activities. However, DSS has poor fat solubility and is unstable due to its o-phenol hydroxyl and α-hydroxy carboxylic acids.

The Enhancer-Promoter-Mediated Transcription During Neurite Regrowth of Injured Cortical Neurons.

Brain injuries can result from accidents, warfare, sports injuries, or brain diseases. Identifying regeneration-associated genes (RAGs) during epigenome remodeling upon brain injury could have a significant impact on reducing neuronal death and subsequent neurodegeneration for patients with brain injury. We previously identified several WNT genes as RAGs involved in the neurite regrowth of injured cortical neurons.

Short-chain fatty acids in gut microbes are an important source of lipids. The causal effect of lipid metabolism/fatty acid metabolism pathways on PE exposure is unknown.

Association between FEV/FVC levels and all-cause mortality in the general population.

Background: The ratio of the forced expiratory volume in 1 s (FEV) to the forced vital capacity (FVC) is an essential tool for the diagnosis of chronic obstructive pulmonary disease (COPD). However, the relationship between levels of FEV/FVC and mortality in the general population remains unclear, particularly its non-linear relationship. Therefore, we aimed to explore the association between the FEV/FVC and all-cause mortality in the general population.

Switching on and off the spin polarization of the conduction band in antiferromagnetic bilayer transistors.

Antiferromagnetic conductors with suitably broken spatial symmetries host spin-polarized bands, which lead to transport phenomena commonly observed in metallic ferromagnets. In bulk materials, it is the given crystalline structure that determines whether symmetries are broken and spin-polarized bands are present. Here we show that, in the two-dimensional limit, an electric field can control the relevant symmetries.

Melatonin suppresses PD-L1 expression and exerts antitumor activity in hepatocellular carcinoma.

Melatonin, also known as the pineal hormone, is secreted by the pineal gland and primarily regulates circadian rhythms. Additionally, it possesses immunomodulatory properties and anticancer effects. However, its specific mechanism in hepatocellular carcinoma (HCC) remains unclear, particularly regarding its effect on HCC-mediated immune escape through PD-L1 expression.

First, we developed a dynamic load simulation approach and derived a calculation formula for shield-soil friction.

The structural basis for the human procollagen lysine hydroxylation and dual-glycosylation.

The proper assembly and maturation of collagens necessitate the orchestrated hydroxylation and glycosylation of multiple lysyl residues in procollagen chains. Dysfunctions in this multistep modification process can lead to severe collagen-associated diseases. To elucidate the coordination of lysyl processing activities, we determine the cryo-EM structures of the enzyme complex formed by LH3/PLOD3 and GLT25D1/ColGalT1, designated as the KOGG complex.

Major depressive disorder on a neuromorphic continuum.

The heterogeneity of major depressive disorder (MDD) has hindered clinical translation and neuromarker identification. Biotyping facilitates solving the problems of heterogeneity, by dissecting MDD patients into discrete subgroups. However, interindividual variations suggest that depression may be conceptualized as a "continuum," rather than as a "category.

Improving the fast-charging capability of NbWO-based Li-ion batteries.

The discovery of Nb-W-O materials years ago marks the milestone of charging a lithium-ion battery in minutes. Nevertheless, for many applications, charging lithium-ion battery within one minute is urgently demanded, the bottleneck of which largely lies in the lack of fundamental understanding of Li storage mechanisms in these materials. Herein, by visualizing Li intercalated into representative NbWO, we find that the fast-charging nature of such material originates from an interesting rate-dependent lattice relaxation process associated with the Jahn-Teller effect.
