background and objectives:hbv and htlv-i are life threatening infectious agents in patients who receive blood and blood products. although serological methods have been proved to be useful, detection of these viruses has remained a challengingissue due to the many obstacles. by the advent of nucleic acid testing methods, especially in multiplex format, more precise detection is possible.the obj...

many results were proved on the structure of finite groups with some‎ ‎restrictions on their real elements and on their conjugacy classes‎. ‎we‎ ‎generalize a few of these to some classes of infinite groups‎. ‎we study groups in which real elements are central‎, ‎groups in which real elements are $2$-elements‎, ‎groups in which all non-trivial classes have the same finite size and $fc$-groups w...

during 2009-10, real time rt-pcr and conventional rt-pcr techniques used for detecting btvs rna in 310 blood samples. for real time and gel based rt-pcr segment-1 and segment-10 selected as conserve genes to search any btv strains. using these methods, 58 (%18.7) and 14 (%4.5) positive samples were detected among the clinically suspected sheep. sensitivity of both molecular techniques evalua...

background: with the increasing concern for health and nutrition, dietary fat has attracted considerable attention. the composition of fatty acids in the diet is important because they are associated with major diseases including cancers, diabetes, and cardiovascular disease. the fatty acid synthase (fasn) and stearoyl-coa desaturase (delta-9-desaturase) (scd) genes affect fatty acid compositio...

background gastric cancer is the second leading cause of cancer-related deaths worldwide and it seems that environmental and lifestyle factors and infection with helicobacter pylori (h. pylori) have a major role in the etiology of gastric cancer. objectives the aim of this study was to investigate the presence of h. pylori dna in archival gastric tissues of patients with gastric cancer disease ...

water is one of the most vital constituents in plants. in this research, for an estimation of leaf moisture content, the variation of capacitance was employed. the variations were measured via designed and manufactured capacitive sensors. the objective of the research was to estimate leaf moisture content by measuring its capacitance for five agronomic crops. experiments for measuring leaf capa...

background: preeclampsia (pe) is one of the most complex and life-threatening pregnancy disorders and is considered as a major cause of mortality among mothers and fetuses worldwide. although the exact etiology of pe is not well known several lines of evidence support an immunological etiology for pe. objective: to investigate the differences in the expression of tlrs 2, 4, 5, and 6 and a group...
