Deubiquitinating enzyme USP2 alleviates muscle atrophy by stabilizing PPARγ.

Insulin resistance, a hallmark of type 2 diabetes, accelerates muscle breakdown and impairs energy metabolism. However, the role of Ubiquitin Specific Peptidase 2 (USP2), a key regulator of insulin resistance, in sarcopenia remains unclear. Peroxisome proliferator activated receptor γ (PPARγ) plays a critical role in regulating muscle atrophy.

Trajectories of general and central obesity beyond middle age in relation to late-life cognitive decline and dementia.

Objective: The objective was to evaluate the longitudinal patterns of central and general obesity, identify their genetic and behavioral risk determinants, and investigate the association of distinct obesity trajectories beyond middle age with subsequent cognitive decline and the risk of developing dementia in late life.

Methods: Using a nationally representative, longitudinal, community-based cohort, we examined trajectory patterns of obesity over a 14-year span beyond middle age employing latent mixture modeling. We then evaluated their relationship with subsequent cognitive decline through linear mixed models and with the risk of developing dementia using Cox models, adjusting for confounding variables.

Preparation and Adsorption Properties of Sodium Trimetaphosphate Crosslinked Porous Corn Starch.

The crosslinked porous corn starch was prepared by two steps: the native corn starch was hydrolyzed by α-amylase and glucoamylase, then the porous corn was crosslinked by sodium trimetaphosphate (STMP). The morphology and size of granules, spherulites, crystal type, molecular structure, swelling properties, thermal stability and adsorption properties of the crosslinked porous starch were investigated. The results indicated that a lot of holes formed in the porous starch, and the particle size of starch granules decreased.

Examining spatiotemporal dynamics of CO emission at multiscale based on nighttime light data.

Carbon emissions have increasingly been the focus of all governments as countries throughout the world choose carbon neutrality as a national development strategy. The analysis of the spatiotemporal dynamics of CO emission has emerged as a significant research topic considering the dual-carbon goal. In this research, we explore the spatiotemporal changes of CO emission at different scales based on nighttime light data.

Immune Profile Differences between IgG4-Related Diseases and Primary Sjögren's Syndrome.

Purpose: Immunoglobulin G4-related disease (IgG4-RD) share clinical features with primary Sjögren's syndrome (pSS). This study aimed to identify altered serological parameters and potential biomarkers of IgG4-RD and pSS.

Methods: Forty IgG4-RD patients, 40 pSS patients, and 40 healthy controls (HC) were enrolled in this study.
