hybrid rice varieties are potentially higher yielding than the best inbred varieties and perform better under adverse conditions of drought and salinity. one of the major impediments for seed production of hybrid rice is incomplete panicle exsertion in the cytoplasmic male sterile lines. the unexserted spikelets which are left inside the flag leaf sheath remain unfertile. this research was focu...
some adipocytokines are cardioprotective or pro-inflammatory for cardiovascular system. chronic infection with chlamydia pneumoniae and helicobacter pylori has been also considered as novel risk factors for atherosclerosis. the main aim of the current population-based study is to investigate the potential link between circulating adipocytokines and chlamydia pneumoniae or helicobacter pylori ig...
background: breast cancer is one of the main life-threatening diseases which a woman may face during her life. several lifestyle factors such as weight gain, obesity, fat intake and decreased level of physical activity are associated with breast cancer risk. in vitro and vivo studies showed that, linoleic acid (la) is one of the main fatty acids composition of nigella sativa. the objective wa...
melissa (melissa offcinalis l.), a member of a lamiaceae family, is a medical plant. the main most important pharmacological properties can be soothin, strengthening nerve, carminative and memory booster. the presence of heavy metals is one of important environmental stresses that can reduce growth and production of types of reactive oxygen. in the present study, the effect of copper sulfate (c...
to study the effects of biofertilizers on physiological and morphological characteristics, as well on essential oil content in dragonhead (dracocephalum moldavica), an experiment was conducted at tarbiat modares university in 2009. the studied factors were: vermicompost (0, 15, 30% v/pot), azotobacter (inoculated and non-inoculated), and phosphatic biofertilizer (inoculated and non-inoculated)....
background: mesenchymal stem cells (mscs) are multipotential cells and their therapeutic potency is under intense investigation. studying the effect of different induction factors on mscs could increase our knowledge about the differentiation potency of these cells. one of the most important sources of these factors in mammalian body is platelet. platelet lysate (pl) contains many growth factor...
the purpose of this study was to examine the effectiveness of nanosilver colloid as a new antimicrobial agent against erwinia in tissue culture of sugar beet for the recovery of the contaminated doubled haploid plantlets. the nanosilver colloidal solution of 4000 ppm was diluted in different concentrations (0, 50, 75, 100 and 125 ppm) and was added to the solid ms medium. in a factorial experim...
background and purpose: the aim of this research is to determine the factors contributing to academic attrition among day – course students of lorestan university of medical sciences. methods: in this case – control study all the day – course students who had at least one semester of an average mark under 12 in academic year 2000-2001 were chosen and then the same number of students with an ave...
abstract: in this paper, the results of experimental and numerical simulation of low velocity impact process have been carried out to investigate energy absorption of composite sandwich panels with 3d woven fabrics of glass fibers and epoxy resin. for this purpose, diagrams of force-displacement of the quasi-static and quasi-dynamic impact tests were studied. for the finite element simulation, ...
three hundred and fifteen day -old chickens were used to test the relationship between oxygen-derived free radicals and the biochemical, hematological and pathological alterations(associtd with ascites). they were randomly divided into three experimental groups and ascites were developed in two groups of animals by exposing them to low temperature or administration of triiodothyronine (t3,), an...
