“Nonaqueous capillary electrophoresis coupled
to UV-vis detection is employed for the fingerprint analysis of Zanthoxylum nitidum. A reliable separation of the analytes in Z. nitidum was performed by using methanol-water solution (4:1, v/v) containing 100 mM sodium acetate (pH* 5.0) as electrolyte solution. Under the conditions studied, the fingerprint of Z. nitidum was obtained within 50 min. The samples from 11 sources NSC 640488 showed fair similarity. The fingerprint was used to identify and evaluate the consistency of the herb. The Z. nitidum was well distinguished from Z. nitidum var. fastuosum, a variety in traditional Chinese medicine by comparing the fingerprints of each herb at the same
“Purpose of review\n\nThere is increasing interest in complementary and holistic approaches for cancer prevention and management. We sought to review the latest literature regarding dietary interventions for prostate cancer with a special emphasis on dietary fat and carbohydrate BEZ235 inhibitor intake for modulating prognosis among men with prostate cancer.\n\nRecent findings\n\nSeveral recent prospective trials have investigated various dietary and lifestyle investigations on malignant prostate tissue biology. These interventions included LY2835219 a very low-fat (12% fat kcals) vegan diet with various supplements and lifestyle changes, a more traditional low-fat diet (25% fat kcals) with flaxseed supplementation, and a low-glycemic index diet. Low-glycemic index and very low-fat vegan diets (with supplements and lifestyle changes) alter tumor biology as assessed by tumor gene expression changes, with a common mechanism perhaps being weight loss whereas no effects were seen with a traditional low-fat diet. In mice, either very
low-fat or low-carbohydrate diets significantly slow tumor growth independent of weight loss. Epidemiologic and preclinical data also suggest cholesterol intake and serum cholesterol levels may be linked with the development and progression of prostate cancer.\n\nSummary\n\nSmall clinical trials suggest that tumor biology can be altered by either a vegan low-fat diet or eliminating simple carbohydrates accompanied by weight loss. Larger and longer term studies are needed to determine the clinical relevance of these findings.”
“Zinc oxide (ZnO) has recently been reported to exhibit electrochemical supercapacitive properties. We demonstrate, for the first time, a nanocrystalline (< 10 nm) composite powder electrochemical supercapacitor in which ZnO-added manganese oxide is used as the active electrode material.
