objective: diabetes mellitus type 2 is one of the most widespread chronic metabolic diseases. in most cases, this type of diabetes is associated with alterations in levels of some inflammatory cytokines and hormones. considering anti-inflammatory properties of plant extracts rich in ascorbic acid (vitamin c) and alpha-tocopherol (vitamin e), anti-diabetic properties of these two well-known anti...
core-shell 12-tungstophosphoric acid/tio2 (hpw/tio2) nanoparticles at 10 and 20% of hpw have been synthesized by simple in-situ sol- gel method. characterization of the samples was carried out by x-ray diffraction (xrd), scanning electron microscopy (sem), fourier transform infrared (ftir). the x-ray diffraction patterns of as prepared solid samples, indicated characteristic peaks of titania wi...
objective: an association between high homocysteine levels and proteinuria in diabetic nephropathy has been shown. on the other hand, supplementation with folic acid lowers homocysteine concentration. we have studied the effects of folic acid supplementation on proteinuria in type 2 diabetic patients with overt proteinuria. materials and methods: forty five (29 men and 16 women) type 2 diabetic...
background: skin flap grafting is a popular approach for reconstruction of critical skin and underlying soft tissue injuries. in a previous study, we demonstrated the beneficial effects of two 5α-reductase inhibitors, azelaic acid and finasteride, on tissue survival in a rat model of skin flap grafting. in the current study, we investigated the involvement of nitric oxide and inducible nitric o...
Background: Psoriasis is a common, chronic disease of the skin, in which both genetic and environmental factors play a critical role. The most characteristic lesions consist of red, scaly plaques present particularly over extensor surfaces and scalp. Studies have reported association between psoriasis and many other diseases in both cutaneous and systemic forms of the disease. Several studies w...
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...
