Background: Old age is accompanied by impaired musculoskeletal and nervous system, which may result in low mobility and cognitive problems. This study aims to evaluate the relationship between Physical Activity (PA) and Cognitive Function (CF) among the elderly population. Objectives: ?? Materials & Methods: This is a descriptive cross-sectional study conducted on 200 old people who were memb...
Background: DNA vaccines are third generation vaccines which have made promises to combat infectious diseases. Cationic liposomes are used as effective delivery systems for DNA vaccines to generate stronger immunity. Objective: Encapsulation of pcDNA3.1+PA plasmid, encoding protective antigen (PA) of Bacillus anthracis (B. anthracis) into cationic liposomes, and evaluation of its effect on spec...
Introduction: There are strong evidences to support the relation between Physical Activity (PA) and improved health in older adults. So this study aimed to determine the predictors of PA among a group of older adults in northwest of Iran. Methods: In 2016, a randomly sample size of 340 older people in urban regions of Maku, West Azerbaijan, Iran, was recruited to complete Physical Activity ...
A new output structure for class E power amplifier (PA) is proposed in this paper. A series LC resonator circuit, tuned near the second harmonic of the operating frequency is added to the output circuit. This resonator causes low impedance at the second harmonic. The output circuit is designed to shape the switch voltage of the class E amplifier and lower the voltage stress of the transistor. T...
Aims: Low mobility is the 4th common cause of human death. The Trans-Theoretical Model (TTM) is a health behavior change theory that describes the process of how people change their behavior. This study was conucted with the aim of investigating the determinants of Physical Activity (PA) behavior based on the TTM in 30-50-year-old individuals. Materials and Methods: In this cross sectional des...
Propionic acid (PA) is a short chain fatty acid, a common food preservative and metabolic end product of enteric bacteria in the gut. The present study was undertaken to investigate the effect of PA on liver injury in male rats. Male western albino rats were divided into two groups. The first group served as normal control, the second was treated with PA. The activities of serum hepatospecific ...
عنوان بررسی بروز پروتئین c-kit (cd117) در چهار تومور خوش خیم و بدخیم شایع غدد بزاقی مقدمه و هدف پلئومورفیک آدنوما، آدنوئید سیستیک کارسینوما، پلی مورفوس low-grade آدنوکارسینوما، و موکواپیدرموئید کارسینوما ازجمله نئوپلاسم های شایع غدد بزاقی می باشند که با پیش آگهی های بسیار متفاوتی همراه می باشند. گاهی افتراق این نئوپلاسم ها از یکدیگر به دلیل همپوشانی های هیستوپاتولوژیک می تواند مشکل باشد.c-ki...
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...
A multiwall carbon nanotubes-modified carbon paste electrode (MWCNTs/MCPE) wasfabricated and used to study the electrooxidation of penicillamine (PA) by electrochemicalmethods in the presence of methyldopa (MDOP) as a homogeneous mediator. Theelectrochemical oxidation of PA on the new sensor has been carefully studied. The kineticparameters such as electron transfer coefficient, α, and catalyti...
