Lactation is a complex physiological process regulated by numerous genes and factors. Circular RNA (circRNA), a non-coding RNA, acts as a molecular sponge that sequesters microRNAs (miRNAs) to regulate target gene expression. Although circRNA has been linked to mammary gland lactation, its specific role in yaks remains underexplored.

The Caco-2 cell model has been widely used to assess the intestinal permeability of drug candidates in vitro, owing to its morphological and functional similarity to human enterocytes. While Caco-2 cell assay is considered safe and cost-effective, it is also characterized by being time-consuming. Therefore, computational models that achieve high accuracies in predicting Caco-2 permeability are crucial for enhancing the efficiency of oral drug development.

Ischemic stroke constitutes a multifaceted neurological affliction that spans various cellular types. Lack of dynamic chromatin accessibility data after stroke is one of the obstacles to understanding this process. To gain insights into the variations in transcriptional regulation among various cell types subsequent to a stroke, we employed single-nucleus ATAC-seq to curate a chromatin accessibility compendium from the cerebral cortex of mice subjected to middle cerebral artery occlusion/reperfusion (MCAO/R).

Designing catalysts with well-defined, identical sites that achieve site-specific selectivity, and activity remains a significant challenge. In this work, we introduce a design principle of topological-single-atom catalysts (T-SACs) guided by density functional theory (DFT) and Ab initio molecular dynamics (AIMD) calculations, where metal single atoms are arranged in asymmetric configurations that electronic shield topologically misorients d orbitals, minimizing unwanted interactions between reactants and the support surface. Mn/CeO catalysts, synthesized via a charge-transfer-driven approach, demonstrate superior catalytic activity and selectivity for NO removal.

Background And Purpose: Epilepsy, a globally prevalent neurological disorder, necessitates precise identification of the epileptogenic zone (EZ) for effective surgical management. While the individual utilities of FDG PET and FMZ PET have been demonstrated, their combined efficacy in localizing the epileptogenic zone remains underexplored. We aim to improve the non-invasive prediction of epileptogenic zone (EZ) in temporal lobe epilepsy (TLE) by combining FDG PET and FMZ PET with statistical feature extraction and machine learning.

Bacterial infections and inflammation severely impede wound healing. Here, we developed a zwitterionic hydrogel incorporating MOF/GOx for pH-responsive, controlled drug release. The multifunctional hydrogel embedded with MOF/GOx was successfully prepared through the Schiff base reaction between the copolymer poly[(2-methacryloyloxyethyl phosphorylcholine)-co-(4-formylphenyl methacrylate)] (PMF) and the branched polyethylenimine (PEI) modified by the zwitterionic monomer ((4-hydroxyphenyl)sulfonyl)(4-(trimethylammonio)butanoyl)amide (AB), which possessed excellent injectable and self-healing ability, a highly sensitive and reversible responsiveness to pH changes, and good biocompatibility.

Archaeal peptidoglycan, a crucial component of the cell walls of Methanobacteria and Methanopyri, enhances the tightness of methanogenic cells and their resistance to known lytic enzymes and antibiotics. Although archaeal peptidoglycan endoisopeptidases (Pei) can reportedly degrade archaeal peptidoglycan, their biochemistry is still largely unknown. In this study, we investigated the activity and catalytic properties of the endoisopeptidases PeiW and PeiP using synthesized isopeptides identical to natural substrates.

Rational design of effective cathode host materials is an effective way to solve the problems of serious shuttle and slow conversion of polysulfides in lithium-sulfur batteries (LSBs). However, the redox reaction of sulfur differs from conventional "Rocking chair" type batteries and involves a cumbersome phase transition process, so a single-component catalyst cannot consistently and steadily enhance the reaction rate throughout the redox process. In this work, a hybrid composed of magnetopyrite FeS catalyst-modified with N/S-doped porous carbon spheres (FeS@NSC) is proposed as a novel sulfur host to synergistically promote the adsorption and redox catalysis conversion of polysulfides.

Multiconfiguration pair-density functional theory (MC-PDFT) was proposed a decade ago, but it is still in the early stage of density functional development. MC-PDFT uses functionals that are called on-top functionals; they depend on the density and the on-top pair density. Most MC-PDFT calculations to date have been unoptimized translations of generalized gradient approximations (GGAs) of Kohn-Sham density functional theory (KS-DFT).

Brain damage induced by ischemia promotes the development of cognitive dysfunction, thus increasing the risk of dementia such as Alzheimer's disease (AD). Studies indicate that cellular acidification-triggered activation of asparagine endopeptidase (AEP) plays a key role in ischemic brain injury, through multiple molecular pathways, including cleavage of its substrates such as SET (inhibitor 2 of PP2A, I ) and Tau. However, whether direct targeting AEP can effectively prevent post-stroke cognitive impairment (PSCI) remains unanswered.
