The nervous system is of fundamental importance in the adaptive (hormesis) responses of organisms to all types of stress, including environmental "toxins". Phytochemicals present in vegetables and fruits are believed to reduce the risk of several major diseases including cardiovascular disease, cancers and neurodegenerative disorders. Although antioxidant properties have been suggested as the b...

a fourth-generation ziegler-natta catalyst was prepared to synthesize polypropylene (pp), which was stabilized by in situ polymerization employing lignin as antioxidant. the antioxidant properties of lignin were compared with those of the commercial antioxidant irganox 1010. the presence of lignin in the reaction medium slightly decreased the catalytic activity of the reaction. the isotacticity...

conclusions probable mechanism of suppression of energy generation is suppression of the rise in glucose. results listeria monocytogenes was controlled using 2 mm of osthole. treatment of l. monocytogenes by 2 mm osthole had no effect on the atp level. objectives osthole has antibacterial properties, but its mechanisms of action is still unknown. materials and methods two millimoles of osthole ...

Resveratrol is a dietary phytochemical that has been shown to inhibit proliferation of a number of cell lines, and it behaves as a chemopreventive agent in assays that measure the three stages of carcinogenesis. We tested for its chemopreventive potential against gastric cancer by determining its interaction with signaling mechanisms that contribute to the proliferation of transformed cells. Lo...

Erythromycin was the first macolide discovered in 1952. In 1990s new macrolides including clarithromycin, azithromycin, and dirithromycin were introduced to the market. We provide a review of their structure, pharmacokinetics, mechanisms of action, and indications in dermatology.
