Background and Objective: Aging like many complex traits is the result of interaction between genome and environmental factors and epigenetic mechanisms as a central connector links these two markers. So far, investigations on age-related characteristics and biomarkers predicting survival and risk of death have been carried out, none of which led to an overall consensus among the researchers. I...
سرطان معده (gc) از متداولترین سرطانها و دومین سرطان منجر به مرگ و میر انسانها در اثر سرطان در جهان است. mir-372 عملکردی شبه انکومیری دارد و از طریق ژن هدفش lats2 در انواع سرطانها باعث تهاجم و نیز عدم تنظیم چرخه سلولی، آپوپتوز و تکثیر سلولی می گردد. cd44 در سرطان معده مارکر سطح سلولی بنیادی سرطانی است و باعث تهاجم و متاستاز می گردد. در این مطالعه، بیان mir-372 با ترانسداکشن لنتی ویروس حامل آن در...
RATIONALE Myocardial infarction (MI) is a leading cause of death worldwide. Because endogenous cardiac repair mechanisms are not sufficient for meaningful tissue regeneration, MI results in loss of cardiac tissue and detrimental remodeling events. MicroRNAs (miRNAs) are small, noncoding RNAs that regulate gene expression in a sequence dependent manner. Our previous data indicate that miRNAs are...
RATIONALE Abdominal aortic aneurysms constitute a degenerative process in the aortic wall. Both the miR-29 and miR-15 families have been implicated in regulating the vascular extracellular matrix. OBJECTIVE Our aim was to assess the effect of the miR-15 family on aortic aneurysm development. METHODS AND RESULTS Among the miR-15 family members, miR-195 was differentially expressed in aortas ...
The article presents the study of effectiveness inosine pranobex (IP) in patients with systemic autoimmune diseases (SAD) on background reactivation persistent Epstein-Barr (EBV) infection. Among 380 SAD (systemic lupus erythematosus, vasculitides, rheumatoid arthritis, psoriasis), 144 (37.9%) EBV infection was detected through virus DNA identification using polymerase chain reaction (PCR) thre...
We introduce aligned hierarchies, a low-dimensional representation for music-based data streams, such as recordings of songs or digitized representations of scores. The aligned hierarchies encode all hierarchical decompositions of repeated elements from a high-dimensional and noisy music-based data stream into one object. These aligned hierarchies can be embedded into a classification space wit...
Systems for the archival of musical documents digitally and development of digital music libraries are currently being researched and developed extensively. However, adapting these systems for the archival and retrieval of Malaysian music materials might not be as straightforward due to the distinct differences in musical structure and modes of non-Western music. This paper covers the motivatio...
UNLABELLED miRNAs are a group of small, noncoding RNAs that modulate the translation of genes by binding to specific target sites in the target mRNA. This study investigated the biologic function and molecular mechanism of miR-21 in human cholangiocarcinoma. In situ hybridization analysis of human cholangiocarcinoma specimens showed increased miR-21 in cholangiocarcinoma tissue compared with th...

سرطان مری ششمین عامل مرگ و میرهای ناشی از سرطان در دنیا می باشد. استان گلستان در شمال شرقی ایران یکی از قطب¬های جهانی با شیوع بالای سرطان مری از نوع کارسینومای سلول سنگفرشی (escc) محسوب می¬شود. مکانیسم¬های مولکولی دخیل در این بیماری هنوز بطور دقیق شناخته نشده است. اخیرا نقش mirnaها در پاتوژنز سرطانها نشان داده شده است. در این تحقیق، پروفایل بیانی بیش از هفتصد mirna در نمونه¬های بافتی پارافینه ک...
