absorbed in the intestine mainly through the paracellular pathway. Their oral bioavailability is usually low since this pathway is severely restricted by the presence of the tight junctions. One of the possible strategies for solving this problem would be a controlled and reversible opening of the tight junctions, which could be achieved by compounds called paracellular permeability enhancers (...
Aims. Using XMM Newton data, we investigate the nature of the X-ray emission in the radio relic 1253+275 in the Coma cluster. We determine the conditions of the cluster gas to check current models of relic formation, and we set constraints on the intracluster magnetic field. Methods. Both imaging and spectral analysis are performed, and the X-ray emission is compared with the radio emission. Re...
The Shapley Concentration is the richest supercluster of clusters in the nearby universe and its core is a remarkable complex formed by the ACO clusters A3558, A3562 and A3556, and by the two minor groups SC 1327-312 and SC 1329-314. This structure has been studied in various wavelength bands, revealing that it is probably dynamically very active. In this paper we present 174 new galaxy redshif...
Acquired thrombotic thrombocytopenic purpura is a rare and severe disease characterized by auto-antibodies directed against "A Disintegrin And Metalloproteinase with Thrombospondin type 1 repeats, 13th member" (ADAMTS13), a plasma protein involved in hemostasis. Involvement of CD4+ T cells in the pathogenesis of the disease is suggested by the IgG isotype of the antibodies. However, the nature ...
Rev Esp Cardiol. 2005;58(11):1253-7 1253 Multi-Slice Computed Tomography (MSCT) coronary angiography is emerging as a non-invasive clinically reliable diagnostic tool to detect significant (luminal diameter > 50%) coronary stenosis. The diagnostic accuracy of MSCT is high, but at this point in time, MSCT coronary angiography should be regarded mainly as a research tool and in selected patients ...
در ابتدا، امام زاده های کلاردشت معرفی شدند و ویژگی های آنها از نظر ساختار بنای امام زاده ذکر شد. سپس به طور خاص به بنای امام زاده هادی پرداخته شد .بنای امام زاده هادی دارای دو ستون چوبی پر کار قطور بوده است که امروزه یکی از آنها موجود است. با توجه به کتیبه عربی حک شده بر روی آن، ساخت ستون چوبی مربوط به قرن هشتم تخمین زده شد. موقعیت ستون چوبی باقیمانده در پلان بنا در صفحه 10 به رنگ قرمز مشخص شده...
