سابقه و هدف: ضایعات مزمن پری اپیکال دندان، عبارتند از بروز پاسخ التهابی مزمن در بافت های اطراف انتهای ریشه دندان. نظر به اینکه سلول های t helper، سلول غالب در این ضایعات می باشند، بنابراین این تحقیق با هدف تعیین رابطه میان غلظت il-4 (به عنوان مهم ترین سایتوکاین القا کننده تمایز t helper2) و il-12 (به عنوان مهم ترین سایتوکاین القا کننده تمایز سلول های t helper 1) با اندازه ضایعات مزمن پری اپیکال...
This paper describes a new filtering technique used to detect and eliminate outlying data in two-way satellite time and frequency transfer (TWSTFT) time links. In the case of TWSTFT data used to calculate International Atomic Time (TAI), three main problems have to be considered: the difficulty of recognizing outliers from useful data; the need to avoid deleting useful data; that TWSTFT links c...
Risk prediction models are important to identify individuals at high risk of developing the disease who can then be offered individually tailored clinical management, targeted screening and interventions to reduce the burden of disease. They are also useful for research purposes when attempting to identify new risk factors for the disease. In this article, we review the risk predictionmodels th...
In this issue of Clinical Cancer Research, Xiong and colleagues report that isolated tumor-specific endothelial cells (TECs) from human hepatocellular carcinoma (HCC) are less sensitive to cytotoxic and antiangiogenic drugs when compared to their normal counterparts in vitro (1). The results of this study are in good accord with the growing body of in vivo evidence and clinical data suggesting ...
Temporal and spatial variation of d34S, total sulfur (TS) concentration, and elemental sulfur concentration (S0) in leaves, roots, and rhizomes of Zostera marina was followed between June 2002 and May 2003 at four locations in Roskilde Fjord and Øresund, Denmark. These were related to temporal changes in sediment sulfide concentrations, sulfur pool size, and sulfur pool d34S. The d34S of Z. mar...
