Background and Aim: Migraine is one of the common forms of headaches, but there is no recognized mechanism and etiology for these headaches, although iron deficiency anemia is the important related factor. This study was carried out to find the relationship between migraine headache and iron deficiency anemia. Material and method: In this case-control study, 200 female in the reproductive a...
two year field experiment was carried out on two early maturing varieties of soybean (glycine max (l.) men.) bred in russia. the purpose was to investigate the possibility of production and to study the effects of nitrogen supply on soybean seed yield and yield components. a range of zero to 100 kg n ha in 1995 when plants suffered from water deficiency and zero to 100 kg n ha -1 in 1996 when p...
Abstract Background and Objective: Of the most common hypochromic microcytic anemia are iron deficiency anemia and minor thalassemia, which are common in Iran and their differential diagnosis is extremely important. The level of 25-hydroxy vitamin D is the indication of vitamin D blood status. The aim of this study was to compare serum levels of vitamin D in people with minor thalassemi...
Abstract Background: Iron deficiency is the most common nutritional deficiencies in the world. So that 15% of the total world population is involved. The present study examined the association between iron deficiency anemia and primary hypothyroidism and the prevalence of iron deficiency anemia and primary hypothyroidism, respectively, in patients with iron deficiency anemia and primar...
thrombophilia is a pathological state of increased blood coagulability. it causes problems during pregnancy including preeclampsia, stillbirth, repeated abortions, and detached pair. out of the most prevalent factors causing inherited thrombophilia, protein s (prs), protein c (prc), and antithrombin iii (atiii) deficiency, and factor v leiden (fvl) mutation could be mentioned. this study aimed ...
We consider stochastically modeled chemical reaction systems with mass-action kinetics and prove that a product-form stationary distribution exists for each closed, irreducible subset of the state space if an analogous deterministically modeled system with mass-action kinetics admits a complex balanced equilibrium. Feinberg's deficiency zero theorem then implies that such a distribution exists ...
In this paper, the study of the class of biochemical systems known as zero deficiency networks is extended to the case of time-varying kinetic parameters. We show that the resulting class of nonlinear systems with inputs satisfies a notion of input-to-state stability uniformly over a set of parameters. In particular, the input-to-state stability estimates allow us to characterize the robustness...
