post-traumatic stress disorder (ptsd) is a chronic and progressive disorder that occurs after some traumas and accident. injuries and harm to health caused by motor vehicle accidents (mvas) have become an issue of global concern, as mvas are expected to be the third largest contributor to the worldwide burden of disease by the year 2020. chronic ptsd is a common consequence of mva and that it m...

Vitamin D3 (100 ng 100 g body weight-1 day-1) was administered intraperitoneally (i.p.) to the freshwater mud eel Amphipnous cuchia kept in artificial freshwater, calcium-free freshwater, low-calcium freshwater (0.2 mmol/l CaCl2) or calcium-rich freshwater (13.4 mmol/l CaCl2) for 15 days. Analyses of serum calcium and phosphate levels were performed on days 1, 3, 5, 10 and 15 after the beginnin...

Several groups have examined the possible use of radioiodinated cholesterol esters to achieve selective uptake of radioactivity in the adrenal cortex and have obtained variable results. This study indicates that the tissue distribution profile varies not only with the type of ester, but also with the vehicle employed for administration. Radioiodinated 19-iodocholesterol (125IQ iodocholesteryl p...

The aim of this study was evaluation of interior design of Shoka vehicle with respect to the accommodation for Iranian population and proposing suggestions for customizing design of the vehicle. Methods: This study was a descriptive-analytical study conducted a...

Neuronal nitric oxide synthase (nNOS) plays a role in synaptic potentiation and kindling process.The relationship between nNOS and 5-HT1A receptors also nearly has been specified. In this research,we investigate the role of nNOS on the anticonvulsant effect of 5-HT1A receptors. 24 male (280 ± 30 g) were randomly assigned to four groups (vehicle,NI,Way 100635 and NI + Way100635) (n = 6). ...

Kat-5 was the fourth vehicle to make history in DARPA’s 2005 Grand Challenge, where for the first time ever, autonomous vehicles were able to travel through 100 miles of rough terrain at average speeds greater than 15 mph. In this paper, we describe the mechanisms and methods that were used to develop the vehicle. We describe the main hardware systems with which the vehicle was outfitted for na...

A series of experiments used rats to study the effect of a systemic or intra-amygdala infusion of the benzodiazepine, midazolam, on learning and re-learning to inhibit context conditioned fear (freezing) responses. Rats were subjected to two context-conditioning episodes followed by extinction under drug or vehicle, or to two cycles of context conditioning and extinction with the second extinct...

background: hawthorn species decreases blood pressure and relaxes precontracted vessels. this study aimed at examining the antihypertensive effect and related mechanisms of hydroalcoholic extract of crataegus azarolus subspecies aronia fruit in rats with renovascular hypertension. methods: six groups of male sprague-dawley rats, each containing 6 to 8 rats, were studied. the groups comprised of...
