Abstract:
Hyperuricemia (HUA) has emerged as a global metabolic disorder that poses significant risks to human health. To investigate the effects and mechanisms of Weizmannia coagulans BC99 in alleviating hyperuricemia, we established a hyperuricemia mouse model. The results demonstrate that BC99 significantly downregulates the expression of uric acid (UA) reabsorption proteins in the kidneys and intestines, while upregulating the expression of UA excretion proteins. This modulation leads to a reduction in UA synthesis, mediated through the Nrf2/NLRP3 pathway. Additionally, BC99 intervention restored gut microbiota intestinal dysbiosis in HUA mice, increased the beneficial short-chain fatty acid (SCFA)-producing bacterial genera, and corrected disturbances in amino acid, purine, and pyrimidine metabolism. Collectively, our findings suggest that BC99 exhibits strong anti-hyperuricemic effects and holds promise as a dietary supplement for lowering uric acid levels.

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
