در این پژوهش با استفاده از روش تابع گرین غیر تعادلی و فرمولبندی لانداور- بوتیکر، در مدل بستگی قوی خواص ترابرد وابسته به اسپین از طریق مولکول پلی استیلن در فاز ترانس (trans-pa) متصل شده به دو الکترود فلزی با سطح مقطع محدود، بصورت عددی بررسی میشود. با مطالعه ترابرد همدوس وابسته به اسپین از طریق مولکول pa ، جریان و قطبش اسپینی را در دو حالت بدون حضور رادیکالهای آزاد (حالت پایه) و در حضور رادیکالها...
Background—Palmitoleic acid (cis-16:1n-7), produced by endogenous fat synthesis, has been linked to both beneficial and deleterious metabolic effects, potentially confounded by diverse determinants and tissue sources of endogenous production. Trans-palmitoleate (trans-16:1n-7) represents a distinctly exogenous source of 16:1n-7, unconfounded by endogenous synthesis or its determinants, that may...
Background & Aim: Dietary isomeric trans fatty acids are suspected to increase the risk of coronary artery disease. The fatty acid composition of human adipose tissue is a useful biomarker of the long-term average of dietary fat. In this population-based case-control study the association between trans fatty acids intake and the risk of coronary artery disease was investigated. Patients & M...
Pheochromocytoma is one of recurrent tumors in patients with von Hippel-Lindau (VHL) disease. For bilateral adrenal glands, unilateral adrenalectomy the treatment choice; however, for a single gland, hemiadrenalectomy or tumorectomy can be performed instead to preserve function. Currently, recommended even if pheochromocytomas occur residual tissue. Consequently, insufficiency cannot avoided th...
The cell surface and extracellular matrix polysaccharide, heparan sulfate (HS) conveys chemical information to control crucial biological processes. HS chains are synthesized in a non-template driven process mainly the Golgi apparatus, involving large number of enzymes capable subtly modifying its substitution pattern, hence, interactions effects. Changes localization HS-modifying throughout we...
This article discusses a recent argument made by number of Foucauldian feminists that gender is problematic concept for feminism. They argue the self-evident status enjoys in current feminist theory and politics based on concealment its historical emergence as pathologizing discourse 1950s American psychiatric-sexology, which targeted intersex trans populations. Claiming redeployments risk rein...
A novel low noise trans-impedance amplifier is proposed using low cost 0.18 µm CMOS technology. A resistive-capacitive feedback is used to extend the bandwidth of the amplifier. As the structure is inductor less, it is suitable for low cost integrated optical interconnects. In this paper Improved Particle Swarm Optimization have applied to determine optimal trans-resistance and noise of propose...
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, ...
گیاه بابونه دارویی (Matricaria chamomilla L.) یکی از مهمترین گیاهان دارویی است که در صنایع دارویی و لوازم آرایشی کاربردهای فراوانی دارد. بنابراین، تجزیه و شناخت کامل ترکیبهای گیاه اهمیت بسیار دارد. در این تحقیق سه نمونه بابونه دارویی از مناطق کازرون، همدان و تهران جمعآوری و به روش تقطیر با آب اسانسگیری گردیدند. نمونه اسانس تهران به رنگ سبز تیره بدست آمد. رنگ سبز در اسانس بدلیل وجود ترکیب guai...
