Garcinia Linn. plants having rich natural xanthones and benzophenones with anti-inflammatory activity attracted a great deal of attention to discover and develop them as potential drug candidates. Through screening targeting nitric oxide accumulation in stimulated macrophage, we found that 1,3,5,7-tetrahydroxy-8-isoprenylxanthone (TIE) had potential anti-inflammatory effect. To understand how T...
مقدمه: آنژیوژنز نقش بسیار مهمی در رشد فیزیولوژیکی بافتها و تومورها دارد. با توجه به نقش کلیدی STAT-3 و آنژیوپویتین-1- tie-2 در آنزیوژنز تومور، هدف از پژوهش حاضر بررسی تاثیر 10 هفته تمرین تناوبی شدید بر بیان ژن STAT-3، آنژیوپویتین-1، میزان پروتئین tie-2 و میزان رشد تومور در موش های مبتلا به سرطان پستان بود. روش بررسی: 12 سر موش آزمایشگاهی نژاد BALB/c (سن 8-6 هفته، وزن 05/1 ± 19گرم) پس از القا...
BACKGROUND Receptor tyrosine kinases that include vascular endothelial growth factor (VEGFR)-1, VEGFR-2, and Tie-2 regulate cardiovascular development and physiological and pathological angiogenesis. We were interested in the phenotypic and functional characterization of peripheral blood cells expressing these receptors and their therapeutic potential in vascular injury. METHODS AND RESULTS V...
This paper describes a frequency domain approach for evaluating the impact of tower shadow and wind shear effects (TSWS) on tie-line power oscillations. A simplified frequency domain model of an interconnected power system with a wind farm is developed. The transfer function, which relates the tie-line power variation to the mechanical power variation of a wind turbine, and the expression of th...
Tie-strength has been in the focus of social science research for decades, yet the use of measurement tools or scales has been relatively scarce. The aim of this study was to fill the gap and provide a tool that is able to provide a quantitative and continuous measure of tie strength in social networks. The focus was on virtual communities because the fast expansion of Internet use and the cons...
