Oxidative stress is thought to play a central role in low-density lipoprotein (LDL) oxidation, and the oxidative modification of LDL is thought to be a key factor during early atherogenesis. Therefore, the prevention of LDL oxidation by antioxidants might arrest the progression of atherosclerosis. This study was conducted to determine the effect of glabridin, a natural polyphenolic isoflavone antioxidant isolated from licorice root, on LDL oxidation. The determination of the extent of LDL oxidation was accomplished by measuring the formation of thiobarbituric acid reactive substances (TBARS). The oxidative stress level was assessed using a FORM system/CR 3000 instrument. After the oral administration of a glycyrrhizin-free licorice-root methanol extract (containing glabridin 60 mg) to healthy subjects for 6 months, the subjects' oxidative stress level as well as plasma LDL oxidation decreased by 20%. We conclude that the dietary consumption of glabridin can partially protect LDL from oxidation.
Background: Even mild hyperglycemia is associated with future acute and chronic complications. Nevertheless, many cases of diabetes in the community go unrecognized. The aim of the study was to determine if national electronic patient records could be used to identify patients with diabetes in a health management organization.
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.
