میکروrna ها گروهی از rna های کوچک می باشند که بیان ژن ها را در سطح بعد از ترجمه کنترل می کنند و در پاسخ سلولی به امواج یونیزه کننده نیز نقش دارند. بعلاوه، میکروrna ها به صورت بسیار پایداری در خون وجود دارند و میکروrna های موجود در گردش خون در حال مطرح شدن به عنوان بیومارکرهای مهم جهت تشخیص سرطان و سایر بیماری ها می باشند. در این مطالعه تاثیر امواج یونیزه کننده بر روی سطح سرمی تعدادی از میکروrna...

Current evidence indicates that conventional mechanical ventilation often leads to lung inflammatory response and oxidative stress, while lung-protective ventilation (LPV) minimizes the risk of ventilator-associated lung injury (VALI). This study evaluated the effects of LPV on relief of pulmonary injury, inflammatory response, and oxidative stress among patients undergoing craniotomy. Sixty pa...

Introdution: The present study was conducted to evaluate the effect of miR-143 on the expression of Bcl2 gene at the level of mRNA, cell cytotoxicity in the SaOs-2 cell line (Osteosarcoma) and Hum 63 (Human primary bone cells). Methods: In this experimental study, miR-143 was introduced into the SaOs-2  and Hum 63 cell by the lipofectam 2000 system. Then, the effects of miR-143 on cytotoxicity...

1 Abstract Operational protocols are a valuable means for quality control. However, developing operational protocols is a highly complex and costly task. We present an integrated approach involving both intelligent data analysis and knowledge acquisition from experts that supports the development of operational protocols. The aim is to ensure high quality standards for the protocol through empi...

As reproduction becomes increasingly biomedicalized throughout the globe, reproductive technologies are used in unique ways and imbued with different meanings. This article explores why lower-class women in south India in the 1990s were demanding to have childbirth labors induced with oxytocin drugs while rejecting anesthesia. Cultural constructions of women's reproductive power are evoked and ...

Background: MicroRNA-155 (miR-155) is upregulated during T cell activation, but the exact mechanisms by which it influences CD4+ T cell activation remain unclear. Objective: To examine whether the B and T lymphocyte attenuator (BTLA) is a target of miR-155 during naïve CD4+ T cell activation. Methods: Firefly luciferase reporter plasmids pEZX-MT01-wild-type-BTLA and pEZX-MT01-mutant-BTLA were ...

Objective(s): Various studies have been conducted to reduce the metastatic behavior of cancerous cells. In this regard, ectopic expression of anti-metastatic microRNAs by miR-mimic and miR-restoration-based therapies could bring new insights to the field. In the present study, the consequences of co-transfecting breast cancer cell lines with miR-193b and miR-31 were investigated via invasion an...

Ovarian cancer is often diagnosed in an advanced stage and associated with a high mortality rate. It assumed that early detection of ovarian could improve patient outcomes. Unfortunately, effective screening methods for diagnosis are still lacking. Extracellular RNAs circulating human biofluids can reliably be measured emerging as potential biomarkers cancer. In this systematic review, we prese...
