Researchers from the University of Cauca in Popayan, Colombia have conducted a study on the removal of Helicobacter pylori, a pathogen associated with fecal contamination, through a two-stage gravel filtration system. The study found that the system's efficiency in removing turbidity and color was 16% and 19% for the dynamic gravel filters (DyGF) and 34% and 30% for the up-flow gravel filters (UGF), respectively. However, the system's operation and maintenance limited the reduction of total coliforms, and the presence of H. pylori was higher in treated water than in raw water. The researchers concluded that the implementation of the gravel filtration system without the complement of slow sand filters (SSFs) is not reliable for ensuring water quality and H. pylori control.

A recent report from the University of Tokai in Kanagawa, Japan, discusses the relationship between Helicobacter pylori (H. pylori) infection and oxidative stress. The research suggests that H. pylori infection can lead to the excessive production of reactive oxygen species (ROS), which can cause chronic inflammation in the gastric mucosa. The study also found that the H. pylori-derived virulence factor ml-type VacA can induce intracellular ROS accumulation and autophagy, which can degrade the H. pylori-derived oncoprotein, CagA. However, in certain gastric cancer stem-like cells, oxidative stress-induced autophagy does not occur, leading to the accumulation of CagA and potentially contributing to tumorigenesis. This research has been peer-reviewed and is available in the Journal of Clinical Biochemistry and Nutrition. [Extracted from the article]

A study conducted by Army Medical University aimed to understand the regulatory and functional mechanism of angiopoietin-like protein-4 (ANGPTL4) in gastric epithelial cells infected with Helicobacter pylori (H. pylori). The researchers collected gastric specimens from H. pylori-positive patients and infected mice, and detected the expression of ANGPTL4 in these tissues.
