Optimization of school physical education schedules to enhance long-term public health outcomes.

Introduction: Optimizing school physical education (PE) schedules is crucial for enhancing public health outcomes, particularly among school-aged children.

Methods: Therefore, in this study, a weighted fitness function is developed to evaluate health fitness scores. This function integrates multiple health metrics such as BMI reduction, fitness improvement, calories burned, and heart rate reduction.

Protective effect of histamine microinjected into cerebellar fastigial nucleus on stress gastric mucosal damage in rats.

In the study, we investigated the effect of histamine microinjected into cerebellar fastigial nucleus (FN) on stress gastric mucosal damage (SGMD), and its mechanisms in rats. The model of SGMD was established by restraining and water (21±1°C)-immersion for 3h. The gastric mucosal damage index (GMDI) indicated the severity of gastric mucosal damage.

Glutamate microinjection into the hypothalamic paraventricular nucleus attenuates ulcerative colitis in rats.

Aim: To investigate the effects of glutamate microinjection into hypothalamic paraventricular nucleus (PVN) on ulcerative colitis (UC) in rats and to explore the relevant mechanisms.

Methods: 2,4,6-Trinitrobenzenesulfonic acid (100 mg/kg in 50% ethanol) was instilled into the colon of adult male SD rats to induce UC. A colonic damage score (CDS) was used to indicate the severity of the colonic mucosal damage.

The enhanced effect of lupeol on the destruction of gastric cancer cells by NK cells.

Lupeol, a triterpene, was reported to possess beneficial effects as a therapeutic and preventive agent for a range of disorders. Many studies have confirmed that lupeol possesses strong activities such as antioxidative, antiinflammatory, antiarthritic, antimutagenic, and antimalarial, both in vitro and in vivo, and at its effective therapeutic doses exhibit no toxicity to normal cells and tissues. Lupeol was observed to inhibit the proliferation of gastric tumour cells in a dose-dependent manner, as assessed by MTT assay, and induce the proliferation of NK cells, as assessed by flow cytometry and Western blotting.

Muscimol microinjection into cerebellar fastigial nucleus exacerbates stress-induced gastric mucosal damage in rats.

Aim: To investigate the effects of microinjection of the GABA(A) receptor agonist muscimol into cerebellar fastigial nucleus (FN) on stress-induced gastric mucosal damage and the underlying mechanism in rats.

Methods: Stress-induced gastric mucosal damage was induced in adult male SD rats by restraining and immersing them in cold water for 3 h. GABA(A) receptor agonist or antagonist was microinjected into the lateral FN.

The effect of phloretin on human γδ T cells killing colon cancer SW-1116 cells.

Objective: To explore the effect and mechanism of Phloretin on human γδ T cells killing colon cancer SW-1116 cells.

Methods: γδ T cells were amplified in vitro from human peripheral blood mononuclear cells through isopentenyl pyrophosphate method (IPP). After cocultured different concentrations of Phloretin with γδ T cells or SW-1116 cells for 48h respectively, MTT assay was used to test the growth curve of these two cells; Flow cytometry to test the expression of Granzyme B (GraB), perforin (PFP), CD107a and IFN-γ of γδ T cells; Lactate dehydrogenase (LDH) release assay to test the cytotoxic activity of the γδ T cells on SW-1116 cells; and Western blot to test the Wnt3a expression of the γδ T cells.

Protection of ghrelin postconditioning on hypoxia/reoxygenation in gastric epithelial cells.

Aim: To investigate the protective effect and mechanisms of ghrelin postconditioning against hypoxia/reoxygenation (H/R)-induced injury in human gastric epithelial cells.

Methods: The model of H/R injury was established in gastric epithelial cell line (GES-1) human gastric epithelial cells. Cells were divided into seven groups: normal control group (N); H/R postconditioning group; DMSO postconditioning group (DM); ghrelin postconditioning group (GH); D-Lys3-GHRP-6 + ghrelin postconditioning group (D + GH); capsazepine + ghrelin postconditioning group (C + GH); and LY294002 + ghrelin postconditioning group (L + GH).

Lateral hypothalamic area mediated the protective effects of microinjection of glutamate into interpositus nucleus on gastric ischemia-reperfusion injury in rats.

We investigated the protective effects of chemical stimulation of cerebellar interpositus nucleus (IN) on gastric ischemia-reperfusion injury (GI-RI) and its possible regulatory mechanisms in rats. Gastric mucosal damage index (GMDI) indicated the severity of gastric mucosal injuries. Transferase dUTP nick end labeling (TUNEL) staining and proliferating cell nuclear antigen (PCNA) were performed to assess gastric mucosal cell apoptosis and proliferation.

Lateral hypothalamic area mediated the aggravated effect of microinjection of Baclofen into cerebellar fastigial nucleus on stress gastric mucosal damage in rats.

Cerebellum, primarily believed as a subcortical somatic motor center, is increasingly considered to be implicated in visceral activities. However, little is known about its regulation on gastrointestinal organs. In this research, we investigated the aggravated effect of microinjection of gamma-aminobutyric acid receptor subtype B (GABA(B)R) agonist, Baclofen into cerebellar fastigial nucleus (FN) on stress gastric mucosal damage (SGMD) and its possible regulatory mechanism.

The electrochemical behavior of p-benzenediol on a self-assembled monolayers Pt electrode modified with N-(2-mercapto-1,3,4-thiadiazol-5-yl)-N'-(4-substituted-arylacetyl) urea.

Two novel N-(2-mercapto-1,3,4-thiadiazol-5-yl)-N'-(4-substituted-arylacetyl) urea compounds have been synthesized, characterized by NMR and MS, and used as self-assembly reagents to form self-assembled monolayers (SAMs) on Pt electrodes. The modified electrodes were characterized by electrochemical methods. The electrochemical behavior of p-benzenediol at the SAMs electrodes was investigated.
