Dietary taurine effect on intestinal barrier function, colonic microbiota and metabolites in weanling piglets induced by LPS.

Diarrhea in piglets is one of the most important diseases and a significant cause of death in piglets. Preliminary studies have confirmed that taurine reduces the rate and index of diarrhea in piglets induced by LPS. However, there is still a lack of relevant information on the specific target and mechanism of action of taurine.

Prognostic impact of deep learning-based quantification in clinical stage 0-I lung adenocarcinoma.

Objectives: To evaluate the performance of automatic deep learning (DL) algorithm for size, mass, and volume measurements in predicting prognosis of lung adenocarcinoma (LUAD) and compared with manual measurements.

Methods: A total of 542 patients with clinical stage 0-I peripheral LUAD and with preoperative CT data of 1-mm slice thickness were included. Maximal solid size on axial image (MSSA) was evaluated by two chest radiologists.

Concurrence of immune thrombocytopenic purpura and thrombotic thrombocytopenic purpura: a case report and review of the literature.

Background: Immune thrombocytopenic purpura and thrombotic thrombocytopenic purpura are both causes of thrombocytopenia. Recognizing thrombotic thrombocytopenic purpura is crucial for subsequent treatment and prognosis. In clinical practice, corticosteroids and rituximab can be used to treat both immune thrombocytopenic purpura and thrombotic thrombocytopenic purpura; plasma exchange therapy is the first-line treatment in thrombotic thrombocytopenic purpura, while corticosteroids are strongly recommended as first-line treatment in immune thrombocytopenic purpura.

Intervention Effect of Taurine on LPS-Induced Intestinal Mechanical Barrier Injury in Piglets.

Taurine has the advantages of being safe, highly efficient, chemically stabile, and biologically active, together with having versatile functions. Presently, it is employed as a veterinary feed additive in animal research. The tight junctions that constitute the intestinal epithelial cells are the most critical structures for ensuring regular and uninterrupted digestion and absorption of food by the intestinal mucosa, while at the same time resisting invasions by toxins.

Metformin inhibits the proliferation of rheumatoid arthritis fibroblast-like synoviocytes through IGF-IR/PI3K/AKT/m-TOR pathway.

Rheumatoid arthritis (RA) is a chronic autoimmune disease in which synovial fibroblast-like cells (FLSs) play an important role in RA development and is known to be lack of effective therapy. Thus, novel therapeutic strategies are greatly needed for treatment of RA. Metformin, a first-line drug for the treatment of type 2 diabetes, has been reported to inhibit the proliferation of a variety of tumor cells.

Antidepressant effect of taurine in chronic unpredictable mild stress-induced depressive rats.

Depression, a psychiatric and dysthymic disorder, severely affects the learning, work and life quality. The main pathogenesis of depression is associated with central nervous system (CNS) dysfunction. Taurine has been demonstrated to exert protective effects on the brain development and can improve learning ability and memory.

[Ultrastructural changes of the skeletal muscle cells of rats subjected to exhausting exercises and the protective effect of vitamin E].

Objective: To investigate the ultrastructural changes of the mitochondria in the skeletal muscle cells of rats subjected to repeated exhausting exercises on treadmill and the protective effect of oral vitamin E.

Methods: Thirty male SD rats were randomized into control group (n=10), exhausting exercise group (n=10) and exhausting exercise group with oral vitamin E treatment (n=10), with the latter two groups taking repeated exhausting running exercises on the treadmill in a course of 4 weeks. At the end of the course of exercises, the rats were sacrificed and the quadriceps femoris muscles isolated for observation the ultrastructures of the skeletal muscle cells by transmission electron microscope (TEM).

[Effect of antioxidant vitamins on the exercise performance of rats].

Objective: To investigate the effect of antioxidant vitamins (vitamin E and vitamin C) on the exercise performance of rats.

Methods: Fifty male SD rats were randomly divided into control group (C), exhausting exercise control group (E), vitamin E group (M1), vitamin C group (M2) and vitamin E plus vitamin C group (M3). The rats in the exercising groups (E, M1, M2, M3) were propelled for repeated exhausting runs on the treadmill for 4 weeks.

[Zymohydrolysis with chondroitinase ABC and high performance liquid chromatography used for the determination of hyaluronic acid in shark fin].

A method for the determination of hyaluronic acid in shark fin by high performance liquid chromatography (HPLC) is described. At 37 degrees C, with 0.2 mol/L Tris-HCl buffer solution, hyaluronic acid was converted to the hyaluronic acid disaccharide by zymohydrolysis with chondroitinase ABC.
