Long-term infection with Helicobacter pylori ( H. pylori) leads to elevated serum gastrin levels, which are closely related gastric cancer. Eradication of H . treat the high levels is increasingly challenged by antibiotic resistance. Dopamine (DA) receptor 1 (D R) expressed on G cells in antrum. Parietal produce DA, inhibits somatostatin (SOM) release through D 2 R mucosa. Whether targeted intervention DRs can improve after remains be explored. In this study, human tissue, pylori-infected...

Researches establish an indispensable role of mitochondrial dysfunction in septic cardiomyopathy. We aimed to investigate the effects long noncoding RNA (LncRNA) SOX2 overlapping transcript (SOX2OT) on observed obvious overexpression SOX2OT hearts and cardiomyocytes. Knockdown mice recovered reduced cardiac function, improved membrane potential impaired by lipopolysaccharide (LPS). overexpressed showed opposite situation. In parallel, knockdown cardiomyocytes restored potential, along with...

The honey peach is popular due to its unique flavor. However, the flavor characteristics of peaches cultivated in Yangzhou and Wuxi remain unclear. In this study, profiles five famous peaches, Baifeng (YBF), Zhonghujing (YZHJ), Wanhujing (YWHJ), (WBF), (WWHJ), were investigated using gas chromatography-mass spectrometry (GC–MS) combined with odor activity values (OAVs), electronic tongue (E-tongue) sensory evaluation. A total 84 substances identified by GC–MS 17 odor-active compounds...

Scope Whole‐food‐based strategies to prevent metabolic diseases are growing interests. Agrocybe cylindracea (AC) is a major edible mushroom with high values of nutrition, but little known about its health benefits as portion whole food. Methods and Results Diet‐induced obese, C57BL/6J mice fed an high‐fat diet (HFD) or without AC (3% 5%, w/w in the diet) for 9 weeks. The results show that dietary reduced body weight, adipose accumulation, impairment glucose tolerance, lipid levels, liver...

Background Few efficacious topical therapies exist for chronic rhinosinusitis (CRS). The lack of a reproducible mouse model CRS limits the pilot testing potential novel anti-inflammatory therapies. Although ovalbumin-induced sinonasal inflammation is commonly used, it difficult to reproduce and can generate variable histologic results. In this study, we explore variation in different strains mice various inflammatory cytokines as molecular markers inflammation. Methods Allergic was generated...

Cardiac arrest most commonly occurs outside of the hospital, known as out-of-hospital cardiac (OHCA), and is an important global health problem. Approximately 40% has no clear cause. Hereditary arrhythmias cardiomyopathies factors contribute to arrest.
