normal 0 false false false en-us x-none ar-sa background: the h-reflex is a useful electrophysiological procedure for evaluating the status of the peripheral nervous system, especially at the proximal segment of the peripheral nerve. the purpose of this study is to investigate the relation between triceps surae h-reflex and m- response latencies and thigh length in normal population, in order t...
aim: the aims of this study were to characterize iranian shigella sonnei strains isolated from pediatric cases and evaluate the utility of multilocus variable-number tandem-repeat (vntr) analysis (mlva) for genotyping of local s. sonnei strains. background: s. sonnei has become the dominant species in certain parts of iran. although pfge is still a gold standard for genotyping and source tracki...
normal 0 false false false en-us x-none ar-sa background: stroke is one of the most common causes of disabilities and death all over the world. the mortality rate of stroke is predicted to be doubled by 2030 in the middle east countries. nutrition is an effective strategy in prevention and management of stroke. this study assessed the relationship between various protein types and stroke risk. ...
some 2-iminothiazolidin-4-ones have been synthesized by the reaction of dialkyl acetylenedicarboxylates with thiosemicarbazones. the reaction was performed in the presence of 10 mol% of triphenylphosphine and tetrabutylammonium bromide as a phase transfer catalyst in water as a green solvent. all the synthesized compounds were characterized by their physical and spectral data.
the thiosemicarbazides 3a-c were appeared by reaction of the corresponding substituted hydrazides 1a-c with allylisothiocyanate 2. synthesis of some novel 1,2,4-triazole-thiols 4a-c bearing a pyridyl unit using 1-(x-picolinoyl)-4-allyl-thiosemicarbazides (x = 2,3,4) in an alkaline solution, is reported. also, the s-alkylation of triazole derivatives 5-7a-c is described. the structure of the syn...
various radiometal complexes have been developed for tumor imaging, especially ga-68 tracer. in the present study, the development of a radiogallium bis-thiosemicarbazone complex has been reported. [67ga] acetylacetonate bis(thiosemicarbazone) complex ([67ga] aats) was prepared starting [67ga]gallium acetate and freshly prepared acetylacetonate bis (thiosemicarbazone) (aats) in 30 min at 90°c. ...
sulfonamides are the first effective chemotherapeutic agents used for several years to cure or prevent systemic bacterial infections. in addition, this agents showed anti-carbonic anhydrase and cause cell cycle perturbation in the g1 phase, disruption of microtubule assembly, suppression of the transcription activator nf-y, angiogenesis and matrix metalloproteinase (mmp). in recent years, novel...
فرض کنیم a(x) جبر یکنواخت متشکل از کلیه توابع مختلط مقدار پیوسته بر مجموعه فشرده x باشد که بر intx تحلیلی اند. برای هر 1 جبر لیپشیتس از مرتبه a را که با lip(x,a) نمایش داده می شود به صورت زیر تعریف می کنیم: حال تعریف می کنیم lipa(x,a)=lip(x,a) n a(x) و برای هر x تام و فشرده lipn(x,a) را جبر تمام توابع مختلط مقدار بر x می گیریم که مشتقات آنها تا مرتبه n ام بر x موجود و در (x,a)lip قرار دارند. ج...
it has been reported that different species of euphorbia (euphorbiaceae) have antitumor activity. some reports also show that these plants have potential cytotoxic effect against different cell lines. in a program to screen the cytotoxicity of iranian native plants, euphorbia macroclada boiss. was collected, identified, and the cytotoxic activity of dichloromethane, ethylacetate, methanol extra...
