transfusion-dependent patients such as those suffering from β-thalassaemia develop a fatal secondary haemosiderosis and consequently a selective iron chelator must be used to relieve such iron overload. 3- hydroxypyridin-4-ones are selective for iron(iii) under most biological conditions, but unlike desferrioxamine, are efficiently absorbed when administered orally. in this study, the synthesis...
Altered metabolism in cancer cells is suspected to contribute to chemoresistance, but the precise mechanisms are unclear. Here, we show that intracellular ATP levels are a core determinant in the development of acquired cross-drug resistance of human colon cancer cells that harbor different genetic backgrounds. Drug-resistant cells were characterized by defective mitochondrial ATP production, e...
objective: evaluating the effect of dentin conditioning with edta on microleakage of composite resin restorations, using two etch and rinse and two self-etch adhesives. materials and methods: one hundred and sixty extracted molars received class v cavity preparations right under the cej and were randomly divided into eight groups of 20, usingfour different adhesive systems. these adhesives incl...
The present study demonstrated that an omega (n)-3 fatty acid, ethyl-eicosapentaenoic acid (ethyl-EPA), supplemented diet significantly attenuated the stress/anxiety behavior of rats in the "open field" and elevated plus maze, which was induced by subchronic intracerebroventricular administration of proinflammatory cytokine interleukin (IL)-1beta. Ethyl-EPA also reduced the rise in serum cortic...
This study measured the possible cross-reactivity of hapten-specific IgG antibodies purified from the sera of rabbits sensitized to an albumin-acetaldehyde conjugate [N-ethyl-rabbit serum albumin (N-ethyl-RSA)] with acetaldehyde-phosphatidylethanolamine adducts. The N-ethyl-RSA was coupled to an Affigel-10 column to affinity purify the IgG (anti-N-ethyl-RSA IgG). Dioleoyl-phosphatidylethanolami...
استفاده از فراورده های گیاهی در زمینه های مختلف از دیرباز در اکثر نقاط جهان مرسوم بوده است . اسانسها از جمله فرآورده های مهم موجود در گیاهان می باشند که کاربرد بسیار وسیع و گسترده ای در صنایع داروئی، غذایی و آرایشی بهداشتی دارند. با توجه به این مسئله و نیز رشد روزافزون سرمایه گذاری بر روی اسانسها و منابع تولید آنها، تحقیق در زمینه اسانسهای جدید گیاهی خصوصا اسانس گیاهان داروئی از اهمیت بالائی بر...
Structural modifications of the multipotential carcinogen ethyl carbamate (urethan), CH3CH2—O---CO—-NH2, generally result in dramatic losses of carcinogenic activity, which usually have been assayed by lung adenoma induction and by initiation of skin papillomas in mice (reviewed in Refs. 12 and 20). One exception is ethyl N-hydroxycanbamate, CH3CH2— O—CO—-NHOH, a metabolite of ethyl c...
