اهمیت مطالعه در خصوص گیاهان دارویی از آنجا حاصل می شود که، یک و یا بخش هایی از این گیاهان حاوی مواد ارزشمند دارویی، غذایی و بهداشتی است. سنتز هر یک از این مواد موثره، فرآیندی طولانی و هزینه بر است. در این تحقیق، روغن کنجد با استفاده از امواج التراسونیک استخراج و سپس با gc/ms شناسایی شد. استفاده از این امواج در استخراج ترکیبات مختلف از بافت های گیاهی راندمان عمل و سرعت فرآیند استخراج را افزایش...

The incorporation of enzyme-catalysed reactions as key features in multi-step organic syntheses is becoming more widespread. Various hydrolase and oxidoreductase enzymes have been used in syntheses of antibiotics and compounds of importance in inflammation and heart disease. The employment of enzymes as catalysts in synthetic organic chemistry is becoming widespread; comprehensive recent review...

Recent studies indicate that the induction of apoptosis in human colon cancer cells by certain nonsteroidal antiinflammatory drugs involves increased expression of 15-LOX-1 and synthesis of its major product 13-S-hydroxyoctadecadienoic acid (13-S-HODE). Evidence was obtained that this occurs via a cyclooxygenase-2 (COX-2)-independent mechanism, but the actual mechanism of induction of 15-LOX-1 ...

Lipoxygenases (LOX) are key enzymes for the oxidative metabolism of polyunsaturated fatty acids into biologically active products. Clinical data on comparative levels of various LOX products in tumorigenesis are lacking. Therefore, we examined the profiles of several LOX products (5-LOX, 12-LOX, 15-LOX-1, and 15-LOX-2) by liquid chromatography/tandem mass spectrometry in the major steps of colo...

BACKGROUND Retinol-binding protein 4 (RBP4), a novel adipokine secreted by adipocytes and the liver, has elevated levels in type 2 diabetes mellitus (T2DM). However, its association with human metabolic diseases remains controversial. The present study was designed to investigate the associations of plasma RBP4 levels with oxidative stress, inflammatory markers, and metabolic syndrome (MetS) in...

Melatonin is a phylogenetically well-preserved molecule with diverse physiological functions. In addition to its well-known regulatory control of the sleep/wake cycle, as well as circadian rhythms generally, melatonin is involved in immunomodulation, hematopoiesis, and antioxidative processes. Recent human and animal studies have now shown that melatonin also has important oncostatic properties...
