Angiotensin II (Ang II) exerts complex actions on sympathetic nerve activity and heart rate, but these actions are incompletely understood. We performed three series of experiments in conscious rabbits to analyze the actions of exogenous and endogenous Ang II on renal sympathetic nerve activity and heart rate. (1) Graded intravenous doses of phenylephrine and Ang II suppressed renal sympathetic...
اولویت کانال صوت در سیستمهای مخابرات سیار، ارسال گفتار فشرده با استاندارد مخصوص می باشد. بدلیل وجود کدک گفتار خاص کانال صوت، مخابره داده از طریق مودمهای معمولی موجود ممکن نمی گردد. از ویژگیهای منحصر به فرد این سرویس که در ارسال از طریق کانال داده وجود ندارد، امنیت در امر مخابره می باشد. این ویژگی سبب شده است استفاده از این سرویس در کاربردهای امنیتی که عدم شنود اطلاعات در اولویت بالاتری از نرخ م...
fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...
The direct effects of physical activity interventions on energy expenditure are relatively small when placed in the context of total daily energy demands. Hence, the suggestion has been made that exercise produces energetic benefits in other components of the daily energy budget, thus generating a net effect on energy balance much greater than the direct energy cost of the exercise alone. Resti...
Background and purpose: Fertility is an effective factor on population growth that its influential factors can be changed over time. This study aimed at surveying some effective social, cultural and economic factors on total fertility rate (TFR) in Kermanshah. Materials and methods: The study population included women aged 15-49 years old resident in Kermanshah during 1996, 2006, and 2011....
background: despite the widespread use of respiratory protection equipment in different jobs, the effects of these devices on people’s physiological responses are not well recognized as yet. therefore, the aim of this study is to evaluate the effect of the air purifying respiratory protection equipment on the heart rate. methods: this experimental study was performed in a climate chamber under ...
background: like several other parasites, teladorsagia circumcincta secretes or excretes urea, but nei-ther the rate of efflux nor the possible metabolic sources of the urea has been considered. methods: parasites were maintained by passage through sheep. urea efflux was measured using phe-nol/hypochlorite after treatment with urea aminohydrolase. the kinetics of creatine amidinohy-drolase and ...
The present resaerch was designed to evaluate the effects of Inactivated Spot White Virus with radiation (gamma irradiant WSSV) on survival rate and immunity factors(THC, TPP, PO, SOD, POD) of white leg shrimp. The experiment was done in Bandar Imam Khomeini hatcheries from November 2013 until February 2014. In this study, the survival rate and immunological parameters of shrimp that exposed ...
Background & Aim: Apart from poor cosmetic appearance, the most important potential consequence of spinal deformities is cardiorespiratory function. However, one of the reasons that patients discontinue wearing orthosis seems to be an increase in energy expenditure during activity apart from its cosmetic problem. The purpose of this study was to assess the effect of Milwaukee brace on energ...
