The Ras(17N) dominant negative antagonizes endogenous Ras function by forming stable, inactive complexes with Ras guanine nucleotide exchange factors (GEFs; e.g., SOS1). We have used the growth-inhibitory phenotype of Ras(17N) to characterize two aspects of Ras interaction with GEFs. First, we used a nonprenylated version of Ras(17N), designated Ras(17N/186S), which no longer associates with th...
هدف: بر اساس مطالعه، بسیاری از دانشجویان، سال اول دانشگاه را یکی دوره‌های زمانی پراسترس و چالش‌زای زندگی می‌دانند قادر به سازگاری مناسب با آن نیستند. مطالعه حاضر هدف شناسایی تجارب زیسته دانشجویان پایین در خصوص مشکلات چالش‌های انجام شد. روش: روش پژوهش کیفی نوع پدیدارشناسی بود. داده‌ها استفاده مصاحبه نیمه ساختاریافته جمع‌آوری شد رویکرد 7 مرحله‌ای کلایزی مورد تجزیه تحلیل قرار گرفت. جامعه کلیه آزاد...
Introduction: The aim of this study was to evaluate the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and mean platelet volume (MPV) in patients with recurrent aphthous stomatitis (RAS). Materials and Methods: Eighty patients who were diagnosed with RAS between January 2014 and January 2016 were included in this study. Eighty age- and gender-matched healthy subject...
The challenging characteristics of Smart Grid such as the vast size of covered area and tight requirements of reliability (higher than 0.98) and delay (in terms of second and millisecond) impede the procedure of communication network designing. This paper investigates the problem of network designing subject to the reliability constraint. The main contribution is dividing the problem into two s...
EXTRACT Although there are new ways to portray the brain, colored and computerized encephalography but Coma is still unknown and such as death remain beyond comprehension and knowing. Is not it ? Perhaps because of this, despite knowing that some part of the brain is not yet fully understood all its parts. But knowing the components that working to each other is key for discovering a lot of...
Ras GTPases include the isoforms H-Ras, K-Ras, and N-Ras. Despite their great biochemical and biological similarities, evidence is mounting suggesting that Ras proteins may not be functionally redundant. A widespread strategy for studying small GTPases is the utilization of dominant inhibitory mutants that specifically block the activation of their respective wild-type proteins. As such, H-Ras ...
R-Ras promotes cell adhesion and activation of integrins through a process that is yet unknown. We show here that active R-Ras (38V) promotes the formation of focal adhesions and a spread cell shape. By contrast, the dominant-negative mutant of R-Ras (43N) reduces the number of focal adhesions, leading to the formation of refractile cells. In adherent cells wild-type R-Ras, activated (38V) R-Ra...
background: domestic and industrial wastewaters are mostly treated by biological process such as activated sludge, aerobic pond, and anaerobic treatment. this study focuses on characterizing the quality of sewage sludge in the sultanate of oman chosen from three industrial sewage treatment plants (stps): rusayl industrial estate (rsl.ie); sohar industrial estate (sie); and raysut industrial est...
