Temporal changes in plasma markers of oxidative stress following laparoscopic sleeve gastrectomy in subjects with impaired glucose regulation.

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) is an effective treatment for obesity and associated metabolic complications. Obesity and type 2 diabetes are associated with increased oxidative stress. Previous studies have examined changes in plasma oxidative stress after laparoscopic Roux-en-Y gastric bypass, but there is limited evidence of the effects of LSG.

Bioactive properties and functional constituents of Hypericum androsaemum L.: A focus on the phenolic profile.

Hypericum androsaemum L. ethanol:water extract acted as a lipid peroxidation inhibitor and free radical scavenger. A marked inhibition of the growth of breast, lung, cervical and hepatocellular human carcinoma cell lines was also observed, whereas no toxicity was shown against non-tumor porcine liver cells (>400μg/mL). The extract was also effective in inhibiting nitric oxide production, as an ind...
