background:  the purpose of the present study was to examine whether a first bout of exhaustive exercise can change inflammo-endocrine responses to second subsequent similar exercise on the same day.  cortisol, tnf-α, and adenosin deaminas enzyme (ada) were assessed during a progressive endurance protocol. methods: eight well trained endurance runners (aged 23.13±3.39 years; weight, 66.21±9.47 ...

understanding the function of trichoderma species in the control of phytophthora drechsleri in pistachio orchards is very important.  in this study, the effects of liquid extra-cellular secretions and volatile compounds secreted by 27 isolates of trichoderma harzianum, t. crassum, t. koningii, t.aureoviride, t. asperellum, t. brevicompactum, t.longibrachiatum and t. virens were investigated on ...

curly top disease is one of the important diseases of sugar beet. spatial pattern and population variation of leafhoppers circulifer haematoceps, and c. tenellus, vectors of sugar beet curly top virus, were studied in hamadan province, iran for three years (2007- 2009). sampling was carried out at the early stage of the plant growth, in accordance with planting date for 9 weeks, in 7- 10 day in...

background and aims: glucose-6-phosphate dehydrogenase (g6pd) is the first enzyme in the route of pentose phosphate metabolism. this route fulfills an effective role in removing oxidant metabolites. deficiency of this enzyme causes decline in energy regeneration of red blood cells and hemolysis. in this study, application of fluorescence staining method in diagnosing the frequency of g6pd defic...

modernity and its impacts on urbanism and the change of the concept and the nature of the city which began in qajar era, stands in a sensitive level in pahlavi’s government (1920-1940). in this stage the concept of modernism can be seen as a pattern in cities (tehran in particular) which affects all economic, social, cultural, physical, management and urban planning aspects s. the main question...

introduction: cardiovascular disease is the major cause of morbidity and mortality in developing and developed countries. rapid diagnosis of the thrombosis can be an essential step in management of the stroke. methods: in this work a recently developed radiolabeled streptokinase (stp) tracer was evaluated in an animal thrombotic model using spect imaging and biodistribution studies. locally lab...

for considering and evaluating the economic impacts of sugar beet research on the shift of sugar supply, we need to estimate the parameter of supply shift. having developed an appropriate methodology and using the results of breeding research collected from the main stations of sugar beet research acrossiranfor the period of 1982-2003, the supply shift parameter for sugar was estimated.  this p...

introduction water vapor can spread in molecular, unstable and erratic phase and can also transfer by convection and advection process. this transfer happens from the earth and ocean surfaces to the atmosphere in hot air. this type of transfer is considered as the main pattern. in the studies of the atmosphere, one of the prominent factors to be considered is the complexity of water vapor and i...

Neuropeptide Y (NPY) stimulates the release of GnRH in an estrogen (E2)-dependent manner, which is important in generating preovulatory GnRH surges. We tested the hypothesis that E2 up-regulates NPY's actions by stimulating NPY Y1 receptor (Y1r) gene expression through a mechanism mediated by E2's ability to induce progesterone (P) receptors (PRs). In initial experiments, a specific Y1r antagon...
