Drought stress is one of the serious problems that restricted agronomic plant production worldwide. In molecular level, the harmful effect of drought stress is mostly caused by producing of large amount of reactive oxygen species (ROS). Catalase and Metallothionein genes have a crucial role to mope the hydrogen peroxide (H2O2) resulting reducing oxidative damage. In this research the gene expre...
abstract biometric access control is an automatic system that intelligently provides the access of special actions to predefined individuals. it may use one or more unique features of humans, like fingerprint, iris, gesture, 2d and 3d face images. 2d face image is one of the important features with useful and reliable information for recognition of individuals and systems based on this ...
In structural pattern recognition, given a set of graphs, the computation of a Generalized Median Graph is a well known problem. Some methods approach the problem by assuming a relation between the Generalized Median Graph and the Common Labelling problem. However, this relation has still not been formally proved. In this paper, we analyse such relation between both problems. The main result pr...
background: it has been hypothesized that blastocyst integrin expression changes can affect the spontaneous miscarriage in polycystic ovarian syndromes (pcos). objective: in this study, the profile of integrin genes and proteins was investigated on blastocyst of the pcos experimental mouse model. materials and methods: 30 nmri female mice were equally divided into 3 groups: control, experimenta...
in the recent years deregulation for micrornas expression pattern have emerged as a possible molecular factor for carcinogenesis. it has been reported that the expression of mir-9 was down-regulated in human gastric adenocarcinoma. to figure out the molecular mechanism of this down regulation, the methylation status in promoters of mir-9 family loci were compared in the human gastric adenocarci...
background: oct4b1, a novel variant of oct4, is expressed in cancer cell lines and tissues. based on our previous reports, oct4b1 appears to have a crucial role in regulating apoptosis as well as stress response [heat shock proteins (hsps)] pathways. the aim of the present study was to determine the effects of oct4b1 silencing on the expression of high molecular weight hsps in three different h...
in solvo-hydrothermal method, xrd pattern was indicated presence of intermediate of ammonium octatmolybdate and ammonium tetramolybdate, which were changed to stble phase of ?-moo3 annealing. sem images were indicated nanoparticle with semispheical morphology and tem image was demonstrated nanoparticles with a diameter size of 25nm. also in impregnate method. the xrd pattern was shown high crys...
background: the human leukocyte antigen (hla) matching between organ donor and recipient is an acceptable strategy in clinical transplantation since 1964. however, in bone marrow transplantation, finding matched donors is often problematic. thus new method for down regulation of hla can be an alternative strategy to solve this problem. objective: to examine the effect of serum starvation on hla...
