BACKGROUND MS pathogenesis seems to involve both genetic susceptibility and environmental risk factors. Three sequential factors are implicated in the environmental risk. The first acts near birth, the second acts during childhood, and the third acts long thereafter. Two candidate factors (vitamin D deficiency and Epstein-Barr viral infection) seem well suited to the first two environmental eve...
In this study 5025 records from the Lori-Bakhtiari sheep stud were used to predict phenotypic, genetic and environmental change in ewe traits from 1989 to 2004. Best linear unbiased prediction (BLUP) of breeding values were estimated by Drivative Free Restricted Maximum Likelihood (DFREML) procedure using single and multi-trait animal model. Phenotypic, genetic and environmental trends were cal...
introduction : pancreatic cancer has not been well studied, especially in developing countries. materials and methods : we studied the variations in genetic mutations in pancreatic adenocarcinoma between moroccan and egyptian populations. the molecular pathology of 30 tumors from a large hospital in casablanca, morocco were examined and compared with the findings of 44 tumors from the gharbiah ...
Genetic diversity is one of the important and essential characteristics of any population for its survival. The study of genetic variation in different populations of aquatic organisms is of particular importance in order to protect, stabilize and manage their stocks. Based on studies conducted in recent years, molecular markers have proven that they can be used as indicators of the genetic div...
Despite the valuable results achieved in identification of genes and genetic changes associated with type 2 diabetes (T2D), lack of consistency and reproducibility of these results in different populations is one of the challenges lie ahead in introduction of T2D candidate genes. Therefore, the present review article aimed to provide an overview of the most important genes and genetic variation...
Objective: Estimation of genetic parameters for Kleiber ratio (KR) and genetic trends for pre-weaning weights of Arabi sheep has not been previously conducted.Methods: Data and pedigree information were collected at the Khuzestan Ramin Agricultural and Natural Resources University, Animal Science Research Station, located in southwest Iran, from 2001 to 2008. (Co)variance components and corresp...

Background and Objectives: Environmental conditions in different geographical areas provide a basis for the spread of some diseases. Cutaneous leishmaniasis is a serious threat to public health and is one of the arthropod-borne diseases. The prevalence and distribution of this disease is affected by environmental and climatic factors. The aim of this study was to model the Spatio-temporal va...
Recent studies have provided evidence that common genetic variations could account for a proportion of leukemia in adult or children. To evaluate the contribution of candidate gene association studies to the understanding of genetic susceptibility to acute lymphoblastic leukemia we conducted a systematic review from published studies. The polymorphisms of genes encoding carcinogen-metabolizi...
Genetic engineering innovations are protectable in intellectual property law system as intellectual properties. Protection of many of these innovations in economic, environmental, moral and human rights fundamentals is justifiable. Based on existing fundamentals in field of mentioned aspects, protection of genetic engineering innovations is provided to application of economic, environmental, mo...
