L-selectin, a Ca(2+)-dependent lectin-like receptor, mediates lymphocyte attachment to high endothelial venules (HEV) of peripheral lymph nodes (PLN) during the process of lymphocyte homing. Two endothelial-derived ligands for L-selectin, known as GlyCAM-1 (Sgp50) and CD34 (Sgp90), have been identified by affinity precipitation of lymph node extracts with a chimeric molecule that combines the e...
The last few years have witnessed an enormous study in the area of integrated hydrological modeling with GIS application. In this research, attempt was made to critically look at the application of HEC-GeoHMS which is an extension of ArcView in HEC-HMS; an HEC package which is a new generation of software being developed for rainfall-runoff simulation. The main role of HEC-GeoHMS is to formulat...
پیشبینی جریان رودخانهها با توجه به اهمیت آن در طراحی تأسیسات آبی، آبگیری از رودخانهها، برنامهریزی و بهرهبرداری از مخازن سدها و کنترل فرسایش و رسوب رودخانهها از دیرباز مورد توجه مهندسان آب بوده است. در این تحقیق به پیشبینی روزانه رواناب در حوضه مارون با مدل HEC-HMS پرداخته میشود، تا توانایی و دقت این مدل در پیشبینی رواناب ارزیابی شود. بهاین منظور ابتدا شبیهسازی پیوسته بارش-رواناب بهص...
در ایران همه ساله پهنههای وسیعی از اراضی مرغوب و حاصلخیز سواحل رودخانه و مسیل ها بر اثر عبور جریان های سیلابی فرسایش یافته و تخریب میشوند. بنابراین جهت ساماندهی و مدیریت رودخانهها و کنترل فرسایش لازم است که ضمن شناخت و پیش بینی رفتار هیدرولیکی جریان، نواحی مستعد فرسایش کناری شناسایی گردیده و اقدامات لازم جهت کنترل آنها به عمل آید. به همین علت در تحقیق حاضر وضعیت فرسایش کناری رودخانه بابلرو...
Computer applications to storm runoff prediction have revolutionized the watershed modeling techniques. In general, a watershed is modeled as a system with inputs and outputs (Chow 1964). A system can be lumped or distributed, depending upon the spatial and temporal characteristics of the design variables used in the model. A lumped parameter ignores the variability in space. On the other hand,...
More insight into the mechanism of adhesion of human endothelial cells (HEC) on to polymeric surfaces may lead to the development of improved small-diameter vascular grafts. H EC suspended in 20% human serum-containing culture medium adhere and spread well on moderately water-wettable polymers such as tissue culture polystyrene (TCPS). Earlier it was demonstrated that during adhesion and spread...
OBJECTIVE Preferential IGF-1Ec expression has been firmly associated with skeletal muscle repair mechanisms, post-infarction remodeling of the myocardium, the pathophysiology of endometriosis and prostate cancer biology. Therefore, we have studied the possible biological significance of synthetic Ec peptide, a putative cleavage product of IGF-1Ec in PC-3 cells and C2C12 myoblasts. DESIGN We h...
Retinoids exhibit chemotherapeutic and chemopreventive activities, possibly due to their ability to modulate cell growth, differentiation, and apoptosis. These effects are thought to be mediated by nuclear retinoic acid (RA) receptors (RARs) and retinoid X receptors, each of which includes three subtypes (a, b, and g) that act as transcription factors. To determine whether RARs play a role in m...

Endometrial carcinoma (EC) is a common malignancy of the female genital tract with a poor prognosis. It has been reported that miR-34c is significantly reduced in EC, but research concerning its function in EC is rare. In the present study, the expression of miR-34c was upregulated in the EC cell line, HEC-1-B, by transfecting the cells with hsa-miR-34c-5p mimics. Then, after determining the tr...
