Introduction: The physiological changes in pregnancy lead to the psychological pressures. Therefore, there is a need for applying cognitive behavioral and emotional confronting to encounter these problems. The present research investigated the effect of coping therapy on general health of pregnant women with high risk of genetic abnormalities in their fetus. Methods: The present study was a ...
In order to select the best parents for crossings, plant breeders seek varieties or genotypes with highest genetic dissimilarities. This can be achieved by measuring the similarities among genotypes, using multivariate analysis methods such as cluster analysis. This study aimed to group 50 aerobic and lowland rice genotypes based on biochemical characteristics including Iron, Zinc, Manganese an...

the genetic diversity of a large number of pistachio genotypes grown in iran is not exactly known. most of the studies on genetic diversity of iranian pistachio varieties are based on morphological characteristics or isozyme markers. in the present study, the genetic diversity of selected pistachio cultivars along with some wild species were evaluated by amplified fragment length polymorphism (...
AG represents only one, it’s true that it is very fashionable today, of the new instruments which began to be used lately in the macroeconomic modelling. Here, it may also be mentioned the classification systems, the genetic programming, the models based on agents, the evolutionist games etc. The characteristics of all these methods consist in the effort to detect the internal dynamic processes...
background and aims: chronic hbv infection is one of the most common viral infections in worldwide which many factors such as genetic factors are involved in pathogenesis of disease. gamma interferon (ifn-γ) and its receptor (infgr) play a critical role in the immune response to hbv infection. single nucleotide polymorphisms (snps) are effective on level of gene expression, the aim of this stud...
