Naomaohu lignite (NL) from Hami, Xinjiang, was ultrasonically extracted with a mixed solvent of CS and acetone (in equal volumes) to obtain the extract residue (ER). The ER was then separated based on density differences with CCl to yield the corresponding light residue (NL-L). The composition and structural characteristics of the light residue were characterized by proximate, ultimate, infrared, and thermogravimetric analyses (TG-DTG).

State Key Laboratory of Ecological Safety and Sustainable Development in Arid Lands, Northwest Institute of Eco-Environment and Resources, Chinese Academy of Sciences, Lanzhou, China.

While soil microorganisms underpin terrestrial ecosystem functioning, how their functional potential adapts across environmental gradients remains poorly understood, particularly for ubiquitous taxa. Employing a comprehensive metagenomic approach across China's six major terrestrial ecosystems (41 topsoil samples, 0-20 cm depth), we reveal a counterintuitive pattern: oligotrophic environments (deserts, karst) harbor microbiomes with significantly greater metabolic pathway diversity (KEGG) compared to resource-rich ecosystems. We provide a systematic catalog of key functional genes governing biogeochemical cycles in these soils, identifying: 6 core CAZyme genes essential for soil organic carbon (SOC) decomposition and biosynthesis; 62 nitrogen (N)-cycling genes (KOs) across seven critical enzymatic clusters; 15 sulfur (S)-cycling genes (KOs) within three key enzymatic clusters.

Introduction: The Zika virus (ZIKV) envelope (E) protein is critical for viral replication and host interactions. Although glycosylation of the E protein is known to influence viral infectivity and immune evasion, the specific functional roles of E protein glycosylation in ZIKV infectivity in mosquito cells remain unclear.

Methods: In this study, we generated a deglycosylation mutant ZIKV with a T156I substitution in the E protein and investigated its effects on viral replication and viral-host interactions in mosquito C6/36 cells.

Locoism refers to a neurological disorder in livestock caused by chronic ingestion of locoweeds, which contain toxic alkaloid swainsonine produced by the fungus . Therefore, reducing swainsonine levels not only prevents locoism but may also transform these toxic plants into animal feed. In this study, we identified a pivotal role for the gene in swainsonine biosynthesis.

Adjusting interlayer interactions and proton-conduction pathways of 2D covalent organic frameworks through the rotaxane structures.

Natl Sci Rev

September 2025

Beijing Key Laboratory for Science and Application of Functional Molecular and Crystalline Materials, Department of Chemistry, University of Science and Technology Beijing, Beijing 100083, China.

Covalent organic frameworks (COFs) have great potential as versatile platforms for proton conduction. However, the commonly applied 2D COFs that are easy to design and synthesize have only 1D channels for proton conduction, limiting the formation of continuous hydrogen bonds due to the anisotropy between their crystalline grains. Herein, we report a strategy to construct 3D channels in 2D COFs by using rotaxane structures and eliminate the strong interlayer π-π interactions, facilitating the formation of smooth 3D proton-transfer pathways during guest doping.

Chimeric antigen receptor T (CAR-T)-cell therapy is a promising resolution for solid tumors, but its corresponding clinical translation has been hindered by unsatisfactory therapeutic potency and severe cytokine release syndrome. Herein, tetracycline (Tet)-On inducible human epidermal growth factor receptor 1 (HER1)-targeted CAR-T (Tet-HER1-CAR-T) cells were engineered to enable spatially selective activation at tumor sites by doxycycline (Doxy), which is delivered by pH-responsive stealth liposomal calcium carbonate nanoparticles (Doxy@CaCO-PEG). Compared with the intravenous administration of conventional HER1-CAR-T cells and Tet-HER1-CAR-T cells activated by free Doxy, concurrent intravenous administration of Tet-HER1-CAR-T cells and Doxy@CaCO-PEG leads to the localized tumor activation of Tet-HER1-CAR-T cells and reduced systemic secretion of inflammatory cytokines.

The role of cholesterol metabolism in antiviral immunity has been established, but if and how this cholesterol-mediated immunometabolism can be regulated by specific small molecules is of particular interest in the quest for novel antiviral therapeutics. Here, we first demonstrate that NPC1 is the key cholesterol transporter for suppressing viral replication by changing cholesterol metabolism and triggering the innate immune response via systemic analyses of all possible cholesterol transporters. We then use the Connectivity Map (CMap), a systematic methodology for identifying functional connections between genetic perturbations and drug actions, to screen NPC1 inhibitors, and found that bis-benzylisoquinoline alkaloids (BBAs) exhibit high efficacy in the inhibition of viral infections.

Rhenium and osmium are both siderophilic and chalcophilic, exhibiting a strong affinity for organic-rich materials. This makes the Re-Os chronometer a valuable complement to geochronometers based on lithophile elements. In this review, we begin by discussing how the elemental abundances and isotopic compositions impact sample selection, analytical strategy, and data interpretation.

The stress distribution in Li metal strongly affects the interfacial Li-ion diffusion, thereby influencing the morphology of plated Li and the performance of the battery. Here, we report a mechano-electrochemical coupling strategy that utilizes an arched structured carbon aerogel to achieve stable Li-plating/stripping electrochemistry. The arch-structured carbon aerogel can actively regulate stress distributions in response to the compressive stresses induced by Li deposition, generating the transition of stress from compressive on the convex surface to tensile on the concave surface, which can effectively promote the Li-migration kinetics and thus suppress the non-uniform deposition of Li.

Hypocretin: a promising target for the regulation of homeostasis.

Front Neurosci

August 2025

Beijing Life Science Academy, Beijing, China.

Hypocretin, also known as orexin, is a hypothalamic neuropeptide that regulates essential physiological processes including arousal, energy metabolism, feeding behavior, and emotional states. Through widespread projections and two G-protein-coupled receptors-HCRT-1R and HCRT-2R-the hypocretin system exerts diverse modulatory effects across the central nervous system. The role of hypocretin in maintaining wakefulness is well established, particularly in narcolepsy type 1 (NT1), where loss of hypocretin neurons leads to excessive daytime sleepiness and cataplexy.

Anatomic resection remains a fundamental principle in the surgical management of hepatobiliary diseases, whether performed through traditional open surgery or advanced minimally invasive approaches such as laparoscopic or robotic-assisted techniques. However, a universally accepted and clearly defined anatomical framework for intraoperative anatomical delineation remains lacking. The growing clinical adoption of Laennec membrane-guided anatomical strategies has been associated with notable improvements in surgical efficacy and anatomical precision.

The intramembrane aspartic protease, γ-secretase, is a heterotetrameric protein complex composed of four integral membrane proteins: presenilin (PSEN), nicastrin (NCT), Anterior pharynx defective-1 (APH-1), and presenilin enhancer 2 (PEN-2). These components are sequentially assembled into a functional complex. γ-secretase is ubiquitously expressed in all cells and tissues and exhibits enzymatic activity akin to "molecular scissors" by cleaving various type I transmembrane proteins.

Understanding how athletes mentally simulate and anticipate actions provides key insights into experience-driven brain plasticity. While previous studies have investigated motor imagery and action anticipation separately, little is known about how their underlying neural mechanisms converge or diverge in expert performers. This study conducted a meta-analysis using activation likelihood estimation (ALE) and meta-analytic connectivity modeling (MACM) to compare brain activation patterns between athletes and non-athletes across both tasks.
