Heterogeneity of extracellular vesicles in porcine myoblasts regulates adipocyte differentiation.

The interactions between myogenic cells and adipocytes play an important role in improving carcass traits and the efficiency of energy utilization. However, there are few reports about the interaction between them mediated by small extracellular vesicles (sEV). In this study, sEV derived from porcine primary skeletal muscle stem cells (MuSCs) was found to be involved in the inhibition of porcine primary adipocyte viability, triglyceride content, Oil Red O enrichment and the expression of adipogenic genes.

An effector essential for virulence of necrotrophic fungi targets plant HIRs to inhibit host immunity.

Phytopathogens often secrete effectors to enhance their infection of plants. In the case of Sclerotinia sclerotiorum, a necrotrophic phytopathogen, a secreted protein named SsPEIE1 (Sclerotinia sclerotiorum Plant Early Immunosuppressive Effector 1) plays a crucial role in its virulence. During the early stages of infection, SsPEIE1 is significantly up-regulated.

Spatial proteomics of single cells and organelles on tissue slides using filter-aided expansion proteomics.

Hydrogel-based tissue expansion combined with mass spectrometry (MS) offers an emerging spatial proteomics approach. Here, we present a filter-aided expansion proteomics (FAXP) strategy for spatial proteomics analysis of archived formalin-fixed paraffin-embedded (FFPE) specimens. Compared to our previous ProteomEx method, FAXP employed a customized tip device to enhance both the stability and throughput of sample preparation, thus guaranteeing the reproducibility and robustness of the workflow.

Copper-Catalyzed C(sp)-H α-Acetylation: Generation of Quaternary Centers.

α-substituted ketones are important chemical targets as synthetic intermediates as well as functionalities in natural products and pharmaceuticals. We report the α-acetylation of C(sp)-H substrates R-H with arylmethyl ketones ArC(O)Me to provide α-alkylated ketones ArC(O)CHR at RT with BuOOBu as oxidant via copper(I) -diketiminato catalysts. Proceeding via alkyl radicals R•, this method enables α-substitution with bulky substituents without competing elimination that occurs in more traditional alkylation reactions between enolates and alkyl electrophiles.

Lipid Pneumonia Mimicking Lung Cancer in a Middle-Age Woman.

Lipid pneumonia is exceedingly rare, with only a few reported cases to date. A 46-year-old woman with a history of left breast cancer underwent a left-modified radical mastectomy, adjuvant chemotherapy, and radiotherapy. Despite no known exposure to lipids, she presented with chronic non-productive cough and general malaise.

Stem cell activity-coupled suppression of endogenous retrovirus governs adult tissue regeneration.

Mammalian retrotransposons constitute 40% of the genome. During tissue regeneration, adult stem cells coordinately repress retrotransposons and activate lineage genes, but how this coordination is controlled is poorly understood. Here, we observed that dynamic expression of histone methyltransferase SETDB1 (a retrotransposon repressor) closely mirrors stem cell activities in murine skin.

calculations of second-, third-, and fourth-order partial and inner elastic constants of diamond.

By means ofcalculations, a unified framework is presented to investigate the effect of internal displacement on the linear and nonlinear elasticity of single diamond crystals. The calculated linear and nonlinear elastic constants, internal strain tensor and internal displacement in single diamond crystals are compatible with the available experimental data and other theoretical calculations. The complete set of second-, third- and fourth-order elastic constants and internal strain tensor not only offer a better insight into the nonlinear and anisotropic elasticity behaviors, but also shows us the basic internal mechanical response of diamond.

Local Structure-Induced Selective Interactions Enables High-Performance and Burn-in-Free Organic Photovoltaics.

Oligomeric acceptors (OAs) have attracted considerable attention in the organic photovoltaics (OPV) field owing to their capacity in balancing the merits from both monomeric and polymeric acceptors. A delicate control over the distortion between blocks of OAs usually determines the performance and stability of relevant OPV devices. However, it imposes great complexity to realize a controllable degree of distortion by tuning the skeleton of blocks and the position of linker between blocks.

On the remarkable resistance to oxidation by the Bi cluster.

The reactivity of Bi clusters ( = 2 to 30) with O is found to display even-odd alternations. The open-shell even-sized Bi clusters are more reactive than the closed-shell odd-sized clusters, except Bi, which exhibits no observable reactivity toward O. We have investigated the structure and bonding of Bi to understand its remarkable resistance to oxidation.

Construction and Optimization of a Yeast Cell Factory for Producing Active Unnatural Ginsenoside 3β--Glc-DM.

Ginsenosides are major active components of , which are generally glycosylated at C3-OH and/or C20-OH of protopanaxadiol (PPD) and C6-OH and/or C20-OH of protopanaxatriol. However, the glucosides of dammarenediol-II (DM), which is the direct precursor of PPD, have scarcely been separated from . Because different positions and numbers of the hydroxyl and glycosyl groups lead to a diversity of structure and function of the ginsenosides, it can be inferred that DM glucosides may have different pharmacological activities compared with natural ginsenosides.

Abortion Rights: Perspectives of Academic Scientists in the United States.

In 2022, the US Supreme Court decision in to overturn federal law safeguarding abortion rights led to considerable national debate on abortion and reproductive rights. We report the findings of a survey of academic scientists' perspectives regarding abortion rights, state policies, and the impact of the 2022 Supreme Court decision in . Furthermore, we look at how academic scientists' institutions acted to address the decision.

Dynamic Reorganization Patterns of Brain Modules after Stroke Reflecting Motor Function.

Objective: Advancements in neuroimaging technologies have significantly deepened our understanding of the neural physiopathology associated with stroke. Nevertheless, the majority of studies ignored the characteristics of dynamic changes in brain networks. The relationship between dynamic changes in brain networks and the severity of motor dysfunction after stroke needs further investigation.

Impact of comorbid sleep-disordered breathing on escitalopram treatment in patients newly diagnosed with generalized anxiety disorder: A 12-week prospective observational study.

We aimed to evaluate the presence of sleep-disordered breathing (SDB) in generalized anxiety disorder (GAD) patients and its impacts after 12-week of escitalopram treatment. In this prospective observational study, GAD patients were followed up to determine whether comorbid SDB affects their treatment response. They underwent a home sleep apnea test (HSAT), and oxygen desaturation index ≥5 was considered indicative of SDB.

Molybdenum nanodots act as antioxidants for photothermal therapy osteoarthritis.

Osteoarthritis (OA) manifests as the degradation of cartilage and remodeling of subchondral bone. Restoring homeostasis within the joint is imperative for alleviating OA symptoms. Current interventions primarily target singular aspects, such as anti-aging, inflammation inhibition, free radical scavenging, and regeneration of cartilage and subchondral bone.

The protein segregase VCP/p97 promotes host antifungal defense via regulation of SYK activation.

C-type lectin receptors (CLRs) are essential to execute host defense against fungal infection. Nevertheless, a comprehensive understanding of the molecular underpinnings of CLR signaling remains a work in progress. Here, we searched for yet-to-be-identified tyrosine-phosphorylated proteins in Dectin-1 signaling and linked the stress-response protein valosin containing protein (VCP)/p97 to Dectin-1 signaling.

IMPA1-derived inositol maintains stemness in castration-resistant prostate cancer via IMPDH2 activation.

Acquisition of prostate cancer stem cells (PCSCs) manifested during androgen ablation therapy (ABT) contributes to castration-resistant prostate cancer (CRPC). However, little is known about the specific metabolites critically orchestrating this process. Here, we show that IMPA1-derived inositol enriched in PCSCs is a key metabolite crucially maintaining PCSCs for CRPC progression and ABT resistance.

Biocompatible Metal-Organic Framework-Based Fabric Composite as an Efficient Personal Protective Equipment for Particulate Matter-Induced Pulmonary Injury.

Efficient personal protection has emerged as a crucial approach for reducing pulmonary injury induced by particulate matter (PM). However, current personal protective equipments usually lack essential biosafety concerns and fail to own adsorbing/antioxidant/antibacterial function together, making it a challenge to develop an integrated platform with the above characteristics. Herein, a facile oxygen-free hydrothermal strategy is proposed to synthesize new copper-based metal-organic frameworks, Cu-HHTPs, (HHTP: 2,3,6,7,10,11-hexahydroxytriphenylene), with great adsorbing/antioxidant/antibacterial activity and high biosafety.
