the first step to quantify crop phenology is precise estimation of the parameters, which affect it. these parameters are mainly temperature and photoperiod. this study was conducted with eight sowing dates to quantify response of stem elongation rate (ser) to temperature and photoperiod in wheat (tajan cultivar). the regression models fitted to ser against temperature were flat, logistic, quadr...

Recruiting polymorphonuclear neutrophil granulocytes (PMNs) from circulation and bone marrow to the site of inflammation is one of the pivotal mechanisms of the innate immune system. During inflammation, the enzyme heme oxygenase 1 (HO-1) has been shown to reduce PMN migration. Although these effects have been described in various models, underlying mechanisms remain elusive. Recent studies rev...

In this research, acute toxicity (LC) of zinc oxide nanoparticle on Beluga (Huso huso) andcommon carp (Cyprinus carpio) was studied. The experiment was conducted using theOrganization for Economic Co-operation and Development (No. 202) method. For bothspecies, 96hLC10 was determined to be more than 200 mg/l. To assess the effects of zinc oxidenanoparticles on blood factors, leukocyte index coun...

recent studies on wavelet transform and fractal modeling applied on mammograms for the detection of cancerous tissues indicate that microcalcifications and masses can be utilized for the study of the morphology and diagnosis of cancerous cases. it is shown that the use of fractal modeling, as applied to a given image, can clearly discern cancerous zones from noncancerous areas. in this paper, f...

background helicobacter pylori is responsible for one of the most common human infections and is a major risk factor for stomach ulcer disease and gastric cancer. h. pylori infection has been reported to be associated with generation and development of coronary artery disease (cad). moreover, diabetic patients positive for h. pylori infection showed a higher prevalence of cad compared to h. pyl...

Objective(s): It is now supposed that cytokines released during the burn injuries have a great impact on the immunological and pathological responses after the burn. The main objective of this study was to investigate the expression of some pro-inflammatory genes in the wound, spleen and blood neutrophils during the healing process of burn wounds in a murine model. Materials and Methods: The ex...
