Pulmonary Arterial Hypertension (PAH) is a progressive devastating disease characterized by excessive proliferation of the Pulmonary Arterial Smooth Muscle Cells (PASMCs). Studies suggest that PAH and cancers share an apoptosis-resistant state featuring excessive cell proliferation. MicroRNA-206 (miR-206) is known to regulate proliferation and is implicated in various types of cancers. However,...
BACKGROUND We investigated whether microRNA-206 (miR-206) is abnormally expressed in patients with coronary artery disease (CAD). The potential mechanism by which miR-206 may regulate CAD progression was also studied. MATERIAL AND METHODS A total of 78 CAD patients in the case group and 65 subjects in the control group were enrolled in this study so that the correlation between miR-206 and CAD ...
در این تحقیق، مشتقاتی از دوده حاوی مخلوط فولرن (7% < α) با قابلیت انحلال زیاد در ترکیبات نفتی تهیه شد. مخلوط فولرن های موجود در دوده تجارتی با آمین‌های چرب مانند هگزادسیل آمین واکنش داده شدند و بدین منظور سنتز آنها از دو روش مورد ارزیابی قرار گرفت که در روش اول با استفاده از حلال و روش دوم بدون حلال در فاز گازی و دمای بالا تحت خلاء انجام شد. با تقطیر در خلاء، آمین‌های اضافی شرکت نکرده در واکنش،...
Biofeedback treatment uses electronic or mechanical instruments to relay visual and/or auditory evidence to assist a person in gaining control over a physiologic process or function. In pediatric urology patients, biofeedback treatment is used to promote retraining of pelvic muscles. Figure 1 depicts the pathophysiology of dysfunctional voiding. In the figure, increased pelvic floor tension or ...
MicroRNAs contribute to cancer development by acting as oncogenes or tumor suppressor genes. However, only a few microRNA target genes were determined. We identified a nearly perfect complementarity between miR-206 and the 3'-untranslated regions of both mouse and human notch3. Expression of miR-206 decreased the luciferase activity dose-dependently when cotransfected with the mouse or human no...
RATIONALE In Drosophila, the Hippo signaling pathway negatively regulates organ size by suppressing cell proliferation and survival through the inhibition of Yorkie, a transcriptional cofactor. Yes-associated protein (YAP), the mammalian homolog of Yorkie, promotes cardiomyocyte growth and survival in postnatal hearts. However, the underlying mechanism responsible for the beneficial effect of Y...
Forkhead box protein subfamily P (FOXP) 1 has an important role in the control of gene transcription and is also reported to function as a tumor suppressor. The aim of the present study was to explore the regulatory mechanisms of atherosclerosis by investigating the function of microRNA-206 (miR-206) and the regulatory association between miR-206 and its potential target gene, FOXP1, in vascula...
PURPOSE Activation or overexpression of HER-2/neu is associated with up-regulation of vascular endothelial growth factor (VEGF) in human breast cancer cells in vitro. Preclinical experiments indicate that increased expression of VEGF may in part mediate the biologically aggressive phenotype of HER-2/neu-overexpressing human breast cancer. It was the purpose of this study to: (a). evaluate the a...
هدف از این تحقیق تخمین تنش های موجود در اجزای رام خودرو پژو 405 و پیش بینی عمر خستگی رام می باشد. به طورکلی تنش های موجود در رام را می توان به دو دسته اصلی تقسیم نمود: تنش های مکانیکی که در اثر اعمال بارهای مکانیکی تولید می گردند و تنش های پسماند که پس از عملیات جوشکاری در قطعه بر جای می ماند. نظر به اینکه جوشها همواره به علت شرایط ذاتی خود دچار تمرکز تنش و دارای ریزترک های بیشتری نسبت به بقیه ...
