مقدمه: پزشکی و فن آوری های مربوط به آن، یکی از مسایل قابل توجه در تاریخ کشورهای اسلامی محسوب می شود، اما به نظر می رسد که وضعیت کنونی این حوزه چندان مطلوب نیست. پژوهش حاضر با هدف بررسی وضعیت توسعه فن آوری پزشکی با استفاده از تحلیل پروانه های ثبت اختراع حوزه پزشکی کشورهای اسلامی در پایگاه بین المللی ثبت اختراع آمریکا انجام شد. روش بررسی: این پژوهش، توصیفی و از نوع کاربردی بود و جامعه آن را کل پر...
در این پژوهش تلاش شده تا نقش ژئواکونومیکی دریای خزر در معادلات جهانی و روابط کشورهای منطقه با تاکید بر ترانزیت نفت و گاز مورد بررسی قرار گیرد. لذا با توجه به حوزه مورد مطالعه بهره گیری از شیوه تجزیه و تحلیل عقلانی و منطقی و البته با بازخورد افزایشی مدنظر واقع و براساس نتایج با حاصله به قضاوت در باره فرضیه های طرح شده همت گماشته و نسبت به رد و یا تائید آن اقدام شده است. با مطالعه صورت گرفته نتای...
Abstract Background: Most animal studies have shown that trans-10 and cis-12 isomers of Conjugated linoleic Acid, (CLA) tend to increase insulin resistance. But the effect of equal isomers of CLA (50:50 ratios of cis-9, trans-11: trans-10, cis-12 isomers) on lipid profiles, glucose, and insulin resistance and sensitivity in postmenopausal women is not clear. Methods: In the present study, ...
dear editor multiple sclerosis (ms) is the most common inflammatory demyelinating disease of the central nervous system. ms is characterized by dissemination in time and place. dissemination can be clinically (clinically definite multiple sclerosis) or radiologically by magnetic resonance imaging (mri). correct diagnosis of ms needs dissemination both in time and in place and also exclusion of ...

Background: Variability in speech performance is a major concern for children with cochlear implants (CIs). Spectral resolution is an important acoustic component in speech perception. Considerable variability and limitations of spectral resolution in children with CIs may lead to individual differences in speech performance. The aim of this study was to assess the correlation between auditory ...
In this study, in order to find the suitable tuber promoter, an experiment was conducted in Shahid Beheshti University in 2018. For this purpose, promoter sequences of different tuberous plants were searched at NCBI. Sequences were multiple-aligned and the target primers designed from conserved regions. PCR analysis confirmed the presence of the desired promoter in plants of sweet potato a...

in this paper, absorption spectra of both solution and films of cyano azobenzene polymer are investigated. the analysis of overlapped absorption spectra of polymer, related to trans and cis isomers, shows that the population of cis isomers is higher than trans isomers. it means that, cyano azobenzene molecules have a folded structure in polymer, in thermal equilibrium. presence of cyano molecul...
