Background and Objectives: Reproductive factors are in close relationship with breast carcinogenesis. This matched case-control study was conducted to study the association of reproductive risk factors with the risk of breast cancer (BC) among women in Tehran and northwest of Iran. Methods: This hospital-based case-control study was performed on a total of 432 patients diagnosed with BC with...

Climatic conditions have dried up since the late 5th millennium BC as if Paleoclimate research in the northern hemisphere, particularly Iran and neighboring countries, shows unfavorable climatic conditions and several periods of severe drought during 4th millennium BC. Also, based on environmental sedimentological studies on archaeological sites such as Mafin Abad of Islamshahr and Meymanat Aba...

چکیده فشارش زاویه ای در کانال های همسان(ecap) یکی از پرکاربردترین روش های تغییر پلاستیک شدید می باشد که با ریز کردن دانه ها و ایجاد تکسچر مناسب باعث بهبود استحکام و انعطاف پذیری می شود. در این تحقیق از یک قالب با زاویه داخلی 120 درجه استفاده شد و آلیاژ aa5051 بعنوان ماده مورد آزمایش انتخاب گردید. ecap در 4 پاس و در مسیرهای a، c، ba و bc در دمای c°200 انجام شد. ریزساختار و خواص مکانیکی مورد مطا...
Digestive tract cancers (DTCs) is the most common malignant tumors in the world. Despite surgery and medical technology have witnessed the increasing development and sharp advancement in the past decade, DTCs remain a critical concern with high morbidity and mortality. Since a class of small noncoding RNAs termed miRNAs were identified several years ago, increasing studies have attempted to ill...
Colorectal cancer primarily metastasizes to the liver and globally kills over 600,000 people annually. By functionally screening 661 microRNAs (miRNAs) in parallel during liver colonization, we have identified miR-551a and miR-483 as robust endogenous suppressors of liver colonization and metastasis. These miRNAs convergently target creatine kinase, brain-type (CKB), which phosphorylates the me...
Changes in circulating miRNA profiles have been associated with different diseases. Here we demonstrate the circulating miRNA profile in serum of HCV infected individuals using a microRNA array that profiles the expression of 940 miRNAs. Serum samples from two HCV genotype - 1 and two HCV genotype - 3 infected individuals were compared with healthy controls. Expression levels of miR-134, miR-19...
