Infection with the Gram-negative bacterium Helicobacter pylori remains the most important modifiable risk factor for the development of gastric cancer, a leading cause of cancer-related deaths worldwide. How the interactions between H. pylori and its host shape the gastric environment during chronic infection warrants further investigation. In this issue of the JCI, Palrasu et al. used human cell lines and mouse models to provide mechanistic insight into H. pylori's ability to delay apoptosis in gastric epithelial cells by actively driving the degradation of a proapoptotic factor, SIVA1. Their findings suggest that promoting the survival of gastric epithelial cells has implications not only for H. pylori pathogenesis but for host tumorigenesis.

Anderss (Salicaceae), commonly referred to as Korean willow, is native to East Asia, particularly Korea and China, and it has been used in traditional Korean folk medicine for its potent anti-inflammatory, analgesic, and antioxidant properties. In our ongoing research efforts to discover biologically new natural products, phytochemical analysis on an ethanolic extract of twigs yielded the isolation and identification of ten phenolic compounds (-), including a newly discovered phenolic glycoside () named isograndidentatin D, isolated via HPLC purification. The structure of compound was determined through extensive 1D and 2D NMR spectral data analysis and high-resolution electrospray ionization mass spectrometry (HR-ESIMS).

The WHO has classified Helicobacter pylori as a group 1 carcinogen for stomach cancer since early 1994. However, despite the high prevalence of Helicobacter pylori infection, only about 3% of infected people eventually develop gastric cancer.Biomolecular detections of Helicobacter pylori(HP) were compared using specially modified sensors and fluorine immobilized on a carbon nanotube (HFCNT) electrode, which yielded sensitive results.

(), one of the most prevalent pathogenic bacteria worldwide, is the leading cause of gastritis, gastric intestinal metaplasia, and gastric cancer. Antibiotics, the conventional treatment for eliminating , often lead to severe bacterial resistance, gut dysbiosis, and hepatic insufficiency and fail to address the inflammatory response or gastric mucosal damage caused by infection. In this study, based on 10-week animal experiments, two models of NCUH062003 for the prophylaxis and therapy of infection in C57BL/6 mice were established; a comprehensive comparative analysis was performed to investigate the anti- effect of probiotics, the reduction in inflammation, and repair of gastric mucosal damage.

: Chronic low-grade inflammation occurs in polycystic ovary syndrome (PCOS), and there are many contributing factors. In this study, we aimed to investigate and infections in patients with PCOS and to evaluate the association between these microorganisms and the inflammatory process in the etiology of the disease. : This comparative cross-sectional clinical study was conducted at Balıkesir University Hospital and included 40 female patients diagnosed with PCOS in the gynecology outpatients clinic and 40 healthy female controls.
