background: to assess the endothelial function via noninvasive method, in pregnant women with preeclampsia compared to normotensive pregnant women. materials and methods: brachial artery diameter was measured via ultrasound, in 28 women with preeclampcia in case group and normotensive pregnant women in control group, at rest, after inflation of sphygmomanometer cuff up to 250-300 mmhg, immediat...

background: the aim of this study was to determine phenolic acid composi­tion and anti-parasitic effects of peucedanum caucasicum, p. palimbioides, p. longibracteola­tum and p. chryseum on entamoeba histolytica . methods: methanol extracts of the plant species were prepared by soxhlet extrac­tion. phenolic acid compositions were determined by hplc. anti-prolifera­tive effect of extracts on trop...

diabetes mellitus is the most common endocrine disorders in children. there is a close association between diabetes and other autoimmune disease especially thyroid disorders. as many as 20 percent of insulin dependent diabetic patients may have thyroid antibodies in their serum. the prevalence is 2-20 times greater than observed in normal populations. in this study, 122 patients with diabetes m...

module over a ring is a general mathematical concept for many examples of mathematicalobjects that can be added to each other and multiplied by scalar numbers.in this paper, we consider a module over a ring as a universe and by using the notion of reference points, we provide local approximations for  subsets of the universe.

the concept of an $l$-bornology is introduced and the theory of $l$-bornological spacesis being developed. in particular the lattice of all $l$-bornologies on a given set is studied and basic properties ofthe category of $l$-bornological spaces and bounded mappings are investigated.

a novel method to compute the stability region in power system transient stability analysis is presented. this method is based on the set analysis. the key to this method is to construct the hamilton-jacobi-isaacs (hji) partial differential equation (pde) of a nonlinear system, using which we can compute the backward reachable set by applying the level set methods. the backward reachable set of...

many textbooks include semantically related words and sometimes teachers add synonyms, antonyms, etc. to the words in order to present new vocabulary items without questioning the possible effects. this study sought to investigate the effect of teaching vocabulary through synonym, semantically unrelated, and hyponym sets based on higa’s (1963) proposed continuum. a total of 120 iranian intermed...
