Objective(s): Based on our previous studies about nano-ZnO effects on physiological behaviors, in this study we have investigated the effects of anxiolytic doses of nano-ZnO on electrocardiogram (ECG) sings changes in the restraint and non-restraint ovariectomized (OVX) female rats. Methods: Animals (160-180 g) were divided into: control (non-OVX + saline) and OVX groups that received: s...
introduction: previous studies have indicated that stress levels of glucocorticoid hormones induce impairment of long term memory retrieval, but the underlying mechanisms (genomic or non-genomic) are not clear. to clarify this issue, we investigated the involvement of brain corticosteroid receptors and protein synthesis in the glucocorticoid-induced impairment of memory retrieval. methods: 140 ...
objectives due to the known anti-oxidant and anti-diabetic effects of origanum majorana (om), this study was conducted to survey its effects on oxidative stress and histopathology of renal tissue among diabetic rats. materials and methods in this experimental investigation, 32 male rats, weighing 200 - 250 g, were divided into four groups: 1: control, 2: control receiving treatment with om, 3: ...
two omega-3 fatty acids including docosahexaenoic acid (dha) and eicosapentaenoic acid (epa) are essential for the physiologic function of neuronal cell membrane. normal function of neuronal cell membrane requires appropriate composition of fatty in its structure. present study was designed to compare the effect of short-term and long-term pretreatment with omega-3 fatty acids on scopolamine-in...
in this study, the effects of oleothermal modification on physical and mechanical peroperties of fir wood (abeis sp.) blocks were examined. at first, some blocks of fir wood with 5 × 20 × 120 cm dimensions were prepared. the blocks were treated in soybean oil. the effects of 3 factors such as treatments temperature (180and 200 °c), holding time (12 and 15 h) and initial moisture content of wood...
introduction: it is known that acute and chronic stress induce hormonal and neuronal changes which affecting both pain threshold and nociceptive behaviours. orexin plays an important role in modulation of pain and stress. considering pain modulation during stress and the role of orexin in pain and stress, orexin might be involved in pain modulation during stress.we evaluated the involvement of ...
فولادهای کربنی برای بسیاری از تجهیزات واحدهای آمین که زداینده سولفید هیدروژن یا ترکیبی از سولفید هیدروژن و دی اکسید کربن از هیدروکربنها هستند بکار می روند. این تجهیزات و از جمله خطوط لوله انتقال در اثر عوامل گوناگونی مانند ترکیبات اسیدی شامل سولفید هیدروژن و دی اکسید کربن یا ترکیبات بازی مانند محلولهای آمین و تحت شرایط محیطی، شرایط متالورژیکی و ترکیب شیمیایی جنس لوله ها، روش ساخت و تولید لوله ه...
lncrnaها (long non-coding rnas)، رونوشتهای غیر کد کنندهی پروتئین با طول بلندتر از 200 نوکلئوتید هستند که از طریق ساختار مولکولی ویژهی خود، با سایر مولکولها در میانکنش بوده و از این طریق بر شماری از فرایندهای مهم سلولی تاثیرگذار هستند. بررسی کارکردهای lncrna در مسیرهای متنوع سلولی، به نحو گسترده مورد مطالعه قرار گرفته است. این مولکولها به شکل طبیعی در انواع سلولها بیان میشوند، اما بیان ک...
in the first part of this thesis we explored wetting and its dynamics for small droplets. first, we showed how a simple feature of water droplets on a surface, i.e. laplace pressure, can be exploited to build a micropump. we investigated capillary pumping in microchannels both experimentally and numerically. putting two droplets of different sizes at the in/outlet of a microchannel, will ge...
