Aberrant DNA methylation as the most important reason making epigenetic silencing of genes is a main mechanism of gene inactivation in patients with colorectal cancer. In this study, we decided to identify promoter methylation status of ten genes encoding WNT negative regulators, and measure the expression of DNMT1 enzyme in colorectal cancer samples.(More)
BACKGROUND Cardiac involvement was the major leading cause of death in patients with Kawasaki and IVIG administration reduces cardiac complications. The objective of this study was to determine the frequency of cardiovascular complications and duration of fever with regard to the time of intravenous immunoglobulin (IVIG) administration of patients with(More)
INTRODUCTION Scientific productions have been accelerated in Iran in past decades but its association with health problems and disease burden is doubtful. The aim of this study is assessment of the relationship between scientific productions with disease burden in Iran in PubMed dataset during 2010 to 2014. METHOD The study was performed with the library(More)
BACKGROUND Probiotic therapies with different strains demonstrated some beneficial effects, although some studies did not show any significant effects. This study assessed systematically the current knowledge on the effect of probiotic bacteria on duration of acute rotavirus diarrhea in children compared with control. METHODS The PubMed, Cochrane(More)
Hypoxanthine-guanine phosphoribosyltransferase 1 (HPRT1) is a common housekeeping gene for sample normalization in the quantitative reverse transcriptase polymerase chain (qRT-PCR). However, co-amplification of HPRT1 pseudogenes may affect accurate results obtained in qRT-PCR. We designed a primer pair (HPSF) for pseudogene-free amplification of HPRT1 in(More)
Breast cancer is the most prevalent malignancies among the women that have a high mortality. Previous studies demonstrated that hypericin, a bioactive component of Hypericum perforatum have a cytotoxic effect on the malignant cell lines. However, an anti-carcinogenic activity of hypericin on MCF-7 is uncertain. To investigate the cytotoxic effect of(More)
BACKGROUND Influenza A virus is the most virulent human pathogen and causes the most serious problem. Having epidemiological knowledge about this disease is important. The aim of this study was to determine the prevalence of influenza A/H3N2 virus infection in northern Iran from 2011 to 2013 using the real-time polymerase chain reaction (RT-PCR). METHODS(More)
As environmental factors are important in the development of asthma, genetic factors could have a critical role in the expression of the disease. Hence, we carried out a systematic review to assess the susceptible genes for asthma in Iranian population. We conducted a literature search by using the electronic database PubMed, Biological Abstracts Web of(More)
Obsessive-Compulsive Disorder (OCD) encompasses a spectrum of clinical symptoms characterized by unwanted thoughts coupled with an intense compulsion to act and to repeat behavior fragments in a ritualistic and stereotyped sequence. Obsessive-compulsive symptom due to brain lesions is not rare, but suppression of these symptoms after head trauma is very(More)
Regarding the fact that two thirds of children's life passes in school, it is important for teachers to have enough knowledge about asthma and how to encounter the disease.
