[Asperosaponin VI alleviates TNBS-induced Crohn's disease-like colitis in mice by reducing intestinal epithelial cell apoptosis via inhibiting the PI3K/AKT/NF-κB signaling pathway].

Objectives: To investigate the effects of asperosaponin VI (AVI) on intestinal epithelial cell apoptosis and intestinal barrier function in a mouse model of Crohn's disease (CD)-like colitis and explore its mechanisms.

Methods: Male C57BL/6 mice with TNBS-induced CD-like colitis were treated with saline or AVI (daily dose 150 mg/kg) by gavage for 6 days. The changes in body weight, colon length, DAI scores, and colon pathologies of the mice were observed, and the expressions of inflammatory factors and tight injunction proteins were detected using ELISA and RT-qPCR.

Feed additives for methane mitigation: Modeling the impact of feed additives on enteric methane emission of ruminants-Approaches and recommendations.

Over the past decade, there has been considerable attention on mitigating enteric methane (CH) emissions from ruminants through the utilization of antimethanogenic feed additives (AMFA). Administered in small quantities, these additives demonstrate potential for substantial reductions of methanogenesis. Mathematical models play a crucial role in comprehending and predicting the quantitative impact of AMFA on enteric CH emissions across diverse diets and production systems.

Recent advances of bioaerogels in medicine: Preparation, property and application.

Bioaerogels represent a type of three-dimensional porous materials fabricated from natural biopolymers, and show a significant potential for medical application due to their characteristics of extremely low density, high specific surface area, excellent biocompatibility and biodegradability. The preparation method and parameters of bioaerogels are focused on, and their influence on the structure and properties of bioaerogels are discussed in detail. Then, to match the properties of bioaerogels with the medical applications, this work emphasizes the main properties (including biocompatibility, degradability, and mechanical properties), structural parameters (such as suitable porosity, pore size and high specific surface area), and further summarizes the influence of single-component and composite bioaerogels on their properties.

Kidney Gastrin/CCKBR Attenuates Type 2 Diabetes Mellitus by Inhibiting SGLT2-Mediated Glucose Reabsorption through Erk/NF-κB Signaling Pathway.

Background: Both sodium-glucose cotransporters (SGLTs) and Na+/H+ exchangers (NHEs) rely on a favorable Na-electrochemical gradient. Gastrin, through the cholecystokinin B receptor (CCKBR), can induce natriuresis and diuresis by inhibiting renal NHEs activity. The present study aims to unveil the role of renal CCKBR in diabetes through SGLT2-mediated glucose reabsorption.

LPSGM: A Unified Flexible Large PSG Model for Sleep Staging and Mental Disorder Diagnosis.

We present the Large PSG Model (LPSGM), a unified and flexible framework for sleep staging and disease diagnosis using polysomnography (PSG) data. LPSGM is designed to address the challenges of cross-center generalization in sleep staging and to enable fine-tuning for downstream disease diagnosis tasks. LPSGM introduces a unified training framework for heterogeneous datasets and allows flexible channel input adjustments during inference.
