H pylori infection leads to the upregulation of gastric PrPc expression. This can be linked to H pylori induced hypergastrinemia and increased mucosal PGE(2) and IL-1beta synthesis. H pylori creates a milieu for enhanced propagation of prions in the gastrointestinal tract.
Blood analysis by spectroscopic techniques can provide important information about biochemistry and life processes in it. Blood indices are highly variable, and plenty of factors influence them. The present work describes the combination of two methods-IR and Raman spectroscopies of blood applied to investigate gerontology issues. We carried out a pilot study of 74 blood samples. The donors were differentiated by age with the Partial Least Squares (PLS) analysis of Raman and IR spectra. Analyzing the principal component spectra obtained during PLS processn the most illustrative bands were found in the intervals 2860-3030 cm
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
