OBJECTIVES Glioma is the most common central nervous system tumor. This systematic review and meta-analysis is aimed to systematically assess the association of XRCC1 polymorphisms with the risk of glioma. METHODS Such databases as EMbase, PubMed, The Cochrane Library, the China National Knowledge Infrastructure (CNKI) platforms, VIP and WanFang were searched up to April 2015 to collect case-...
Background and purpose: Dentists are constantly exposed to mercury vapor and its role in the development of many chronic diseases has been proven. Therefore, this study aims to determine the mean concentrations of mercury in samples of blood, urine and area air among Iranian dentists. Materials and methods: This study was conducted based on PRISMA guidelines. Two authors searched Persian and E...
BACKGROUND Previous studies have explored the effect of granulocyte colony stimulating factor (G-CSF) administration on the outcome of assisted reproductive technology (ART), and came into controversial conclusions. The present meta-analysis aims to assess whether G-CSF administration has beneficial effect on the outcome after ART. METHOD The electronic databases Pubmed, Embase and Google Sch...
Increasing epidemiological studies have focused on the associations between interleukin-6 (IL-6) gene -174G>C polymorphism and atherosclerotic diseases, but the results are still controversial. This meta-analysis was designed to identify whether this association exists. PubMed, Embase, Web of Science, Cochrane database, Clinicaltrials.gov and Current Controlled Trials, Chinese Clinical Trial Re...
In the last ten years, the use of gamma-ray spectrometry for geological mapping and mineral exploration has shown considerable growth. With this growth, standardized procedures have been developed for the calibration and processing of the airborne measurements so that they will be independent of survey parameters. This paper describes some of the new developments to convert airborne data to gro...
The FOSB gene is involved in cell proliferation, differentiation and transformation in several tumor types. We investigated whether coding single-nucleotide polymorphisms (cSNPs) and promoter SNPs of FOSB contribute to the development of papillary thyroid cancer (PTC). We also assessed the associations between FOSB SNPs and the clinicopathological characteristics of PTC. One coding SNP (rs22826...
BACKGROUND We examined the associations of alcohol consumption and liver holidays with all-cause mortality and with mortality due to cancer, heart disease, cerebrovascular disease, respiratory disease, and injury using a large-scale prospective study in Japan.
