Objective(s): Atherosclerosis is an important risk factor for coronary heart disease. Neuropeptide Y (NPY) and its receptors, located in peripheral tissue such as white adipose tissue, have been linked to obesity and fat storage. The role of NPY in atherosclerosis has not yet been fully studied, so this study was conducted to further investigate the effect of BIIE 0246, an NPY receptor antagoni...

Objective(s): Traumatic brain injury (TBI) is one of the most common causes of death and disability in modern societies. The role of steroids and melatonin is recognized as a neuroprotective factor in traumatic injuries. This study examined the role of melatonin receptors in the neuroprotective effects of estrogen. Materials and Methods: Seventy female ovariectomized Wistar rats were divided in...

Introduction: There is currently a debate over the interaction between Ca2+ channels and cannabinoid system on learning and memory processing. In this study, we examined the effect of acute injection of cannabinoid agonist (Win- 55212-2) (Win) or antagonist (AM251), following chronic injection of verapamil, as a L-type Ca2+ channels blocker, on passive avoidance (PA) test in male Wistar rats...

Background and Objective: Methylphenidate (MPH), as a central nervous system stimulant, is often used to manage hyperactive disorders. The literature is scarce regarding the behavioral consequences of chronic MPH treatment and the role of involved receptors. Thus, in the current study involved receptors in MPH induced-anxiety, depression and motor activity disorders were evaluated. Materials a...

Rosemary (Rosmarinus officinalis) is a common household plant grows in many parts of the world, including Iran. Rosemary leaves are used in folk medicine as an antispasmodic, analgesic, diuretic and ntiepileptic agent. The objective of this study was to investigate the antinociceptive mechanisms of rosemary extract using a writhing test as a model of visceral pain. Possible antinociceptive mech...

Morphine was used as a remedy for the control of diarrhea centuries before it's sedative-analgesic effect was discovered. Although several mechanisms have been proposed for the morphine-induced inhibition of gastrointestinal transit (OIT), the exact mechanism has not yet been identified. On this basis the possible involvement of the dopaminergic system in morphine-induced inhibition of tra...

during 2003-2004, a number of rhizospheric soil samples were collected of either healthy or symptomatic field grown melon plants infected with fusarium oxysporum f. sp. melonis race1/2 (fom). twenty one bacterial strains capable of inhibiting fom including burkholderia sp., bacillus sp., streptomyces sp. and pseudomonas fluorescens were isolated. the strains colonized roots of “long melon” cult...

a series of angiotensin ii (a ii) receptor antagonist of some substituted 5-(biphenyl-4-ylmethyl) pyrazole were subjected to qsar analysis using hansch and fujita-ban model, by using combination of thermodynamic, electronic, spatial descriptor and presence or absence of substituent respectively. several qsar model were obtained using stepwise regression analysis. two models from both the method...

Der Briefschreiber möchte anhand der Krankengeschichte einer Patientin mit idiopathischer rezidivierender Pleuroperikarditis aufzeigen, dass IL-I-Antagonist Anakinra nicht als Langzeittherapie gegeben werden muss.

Rats can learn to forage among olfactory cues to associate one with reward in only 3 massed trials. The learning is achieved in less than 10 min and results in a memory trace lasting at least 1wk week. To study the neuro-anatomical circuits involved in the memory formation we used immunoreactivity to the immediate early gene c-fos as a marker for neuronal activity induced by the learning. The p...
