A composite index of the ratio of the diameter of the main pulmonary selleck compound artery to the diameter of the ascending aorta and echocardiography-derived RVSP was more strongly related (R(2) = 0.55) to mPAP and was more significantly predictive of PH than either measure alone.
Conclusion: A combination of CT and echocardiographic markers of PH is more closely related to mPAP than either test in isolation. (C) RSNA, 2010″
“Tea (Camellia sinensis L) is one of the most widely popular nonalcoholic beverage, consumed by over two-thirds of the world’s population due to its medicinal, refreshing and mild stimulant effects. Mainly four types of made tea viz., black or red, oolong, green and white are used for tea infusion
(water extract from fermented tea leaf) worldwide. Tea plays a major role in terms of the intake of a number of nutritional trace elements in humans. Besides essential macro- and microelements. experimental studies have demonstrated that the accumulation of significant amount of excess nonessential trace elements in tea leaves may eventually increase the metal body burden in humans. Different literatures have indicated that among different trace elements, levels of aluminium (Al). arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), fluoride
(F) manganese (Mn), and nickel (Ni) in different tea infusions were 0.06-16.82 mg L(-1), trace-1.53 mu g L(-1), trace-0.79 mu g L(-1), below detectable limit-43.2 mu g L(-1), 0.02-40.0 mg L(-1), 0.2-4.54 mg L(-1), 0.1-250 mg L(-1) and BDL-0.16 mg L(-1). respectively.
FK228 chemical structure It has also been reported that in some of the tea infusions, toxic metals exceed the maximum permissible limits stipulated for different OSI-744 cell line countries. In the present review, an attempt has been made to update and evaluate the knowledge of the presence of some selected trace elements in tea leaves, made tea and tea infusion, based on the available literature. Existing reports suggested that the presence of trace elements in green tea is lower than the black tea in most cases. However, the available literatures still appear to have some limits and may need more detailed investigations before reaching the conclusions. (C) 2010 Elsevier Ltd. All rights reserved.”
“Purpose: To analyze the characteristics associated with membranous obstruction of the inferior vena cava (MOVC) associated hepatocellular carcinoma (HCC) and to evaluate the clinical efficacy of transcatheter arterial chemoembolization ( TACE).
Materials and Methods: This retrospective study was approved by an institutional review board, and informed consent was waived. Ninety-eight patients (mean age, 48.5 years +/- 12.9 [standard deviation]) with MOVC were retrospectively evaluated. The diagnosis of Budd-Chiari syndrome was confirmed with results from Doppler ultrasonography, computed tomography, magnetic resonance imaging, and/or inferior venacavography.
