Pregnant rats were administered with BPA or vehicle control once daily via oral gavage from gestational day 1 until parturition.

Prevalence of malnutrition among adult inpatients in China: a nationwide cross-sectional study.

Malnutrition substantially contributes to adverse clinical outcomes. However, no national survey has been conducted to characterize its epidemiology in hospital settings in China. We conducted the China Nutrition Fundamental Data 2020 project among a multistage stratified cluster sample of adult inpatients from 291 study sites across 30 provinces, autonomous regions and municipalities (except for Hong Kong, Macao, Taiwan Province, and the Xizang Autonomous Region, please see MATERIALS AND METHODS for details of the causes) of China to generate reliable data on the prevalence of malnutrition and explore the associated risk factors.

RELMβ sets the threshold for microbiome-dependent oral tolerance.

Tolerance to dietary antigens is critical for avoiding deleterious type 2 immune responses resulting in food allergy (FA) and anaphylaxis. However, the mechanisms resulting in both the maintenance and failure of tolerance to food antigens are poorly understood. Here we demonstrate that the goblet-cell-derived resistin-like molecule β (RELMβ) is a critical regulator of oral tolerance.

B-cell infiltration distinguishes mucosal from skin patterns of rejection in facial vascularized composite allografts.

Rejection monitoring in facial vascularized composite allotransplantation (fVCA) traditionally focuses on skin biopsies. However, mucosal rejection frequently presents with more pronounced signs of immune activity. To explore mechanistic differences between skin and mucosal rejection, rejection and non-rejection biopsies from allograft skin and oral mucosa of nine fVCA recipients were retrospectively analyzed using histology, multiplex immunostaining, and gene expression profiling, with peripheral blood mononuclear cells (PBMCs) quantified via mass cytometry (CyTOF).

Click chemistry-driven asymmetrically modified superhydrophobic/superhydrophilic gelatin sponge for improved dry socket prophylaxis.

Dry socket, a common painful complication after tooth extraction, is typically caused by improper blood clot formation or its premature dislodgement, often exacerbated by bacterial infections. Traditional gelatin sponges, widely used as clinical fillers, provide favorable biocompatibility and hemostatic support but suffer from suboptimal hemostatic efficiency, lack of antimicrobial properties, and insufficient anticoagulant factors, which increase the risk of dry socket. Addressing these limitations, a novel tannic acid cross-linked gelatin sponge has been developed using directional lyophilization.

Hyaluronic acid-conjugated lipid nanocarriers in advancing cancer therapy: A review.

Lipid nanoparticles are obtaining significant attention in cancer treatment because of their efficacy at delivering drugs and reducing side effects. These things are like a flexible platform for getting anticancer drugs to the tumor site, especially upon HA modification, a polymer that is known to target tumors overexpressing CD44. HA is promising in cancer therapy because it taregtes tumor cells by binding onto CD44 receptors, which are often upregulated in cancer cells.
