Soybean polysaccharide fermentation products regulate the air-liquid interface in co-cultured Caco-2 cells by increasing short chain fatty acids transport.

Soybean polysaccharides have a large molecular weight and complex structure, which is not conducive to body absorption and exerting their biological activities. After the in vitro hydrolysate digestion of soybean polysaccharides, their interactions with intestinal epithelial cell monolayers during soybean polysaccharide-derived short chain fatty acids (SCFAs) uptake and transport were determined by co-culturing soybean polysaccharide hydrolysate products with Caco-2 cells. Based on prepared soybean polysaccharide hydrolysates, physicochemical indices and hydrolysate components were explored and the interface characteristics between SCFAs and Caco-2 cells were characterized using interfacial rheology methods for the first time.

[Genetic mutation screening of glucose-6-phosphate dehydrogenase deficiency in Dongguan district].

Objective: To determine the incidence and genotypes of glucose-6-phosphate dehydrogenase (G6PD) deficiency in Dongguan region of Guangdong Province and assess the efficacy and feasibility of flow-through hybridization.

Methods: Peripheral blood samples were randomly selected and detected by modified G6PD/6PGD ratio method. Flow-through hybridization was used to detect 14 G6PD mutations among all samples.

Liver X Receptor Agonist Therapy Prevents Diffuse Alveolar Hemorrhage in Murine Lupus by Repolarizing Macrophages.

Unlabelled: The generation of CD138 phagocytic macrophages with an alternative (M2) phenotype that clear apoptotic cells from tissues is defective in lupus. Liver X receptor-alpha (LXRα) is an oxysterol-regulated transcription factor that promotes reverse cholesterol transport and alternative (M2) macrophage activation. Conversely, hypoxia-inducible factor 1-α (HIF1α) promotes classical (M1) macrophage activation.

A Novel Subset of Anti-Inflammatory CD138 Macrophages Is Deficient in Mice with Experimental Lupus.

Dead cells accumulating in the tissues may contribute to chronic inflammation. We examined the cause of impaired apoptotic cell clearance in human and murine lupus. Dead cells accumulated in bone marrow from lupus patients but not from nonautoimmune patients undergoing myeloablation, where they were efficiently removed by macrophages (MΦ).

Pharmacological inhibition of the mammalian target of rapamycin pathway suppresses acquired epilepsy.

Inhibition of mTOR by rapamycin has been shown to suppress seizures in TSC/PTEN genetic models. Rapamycin, when applied immediately before or after a neurological insult, also prevents the development of spontaneous recurrent seizures (epileptogenesis) in an acquired model. In the present study, we examined the mTOR pathway in rats that had already developed chronic spontaneous seizures in a pilocarpine model.
