Several lines of evidence suggest that brain histamine may be involved in the central control of food intake. The effect of histamine on feeding is mediated through three kinds of receptors (H1, H2, and H3). The present study was designed to investigate the effect of intracerebroventricular injection of histamine, promethazine (H1 antagonist) and ranitidine (H2 antagonist) on food intake of fre...
the aim of this study was to evaluate the effects of three lighting programs on immune system and performance of broiler chickens. a total of 288 seven day-old male broiler chicks (ross-308) were randomly distributed between three treatments. each group was housed in the separated room with eight pen and 12-birds per pen. the management conditions were similar for all treatments throughout the ...
در این پایان نامه، چهار نوع مدل برنامه ریزی پویایی استوکاستیک (sdp) و همچنین برنامه ریزی پویای قطعی (dp) در بهینه سازی بهره برداری از س مخزنی چند منظوره دز ارائه و مقایسه شده اند. چهار نوع مدل برنامه ریزی پویای استوکاستیک از نظر نوع متغیر حالت جریان ورودی و به کار بردن احتمال انتقالی و یا احتمال غیر شرطی با هم تفاوت دارند. برای بررسی سیاستهاهینه به دست آمده از مدلهای مختلف، ایک مدشبه ساز استفاد...
Glucose is a 6-carbon carbohydrate compound present in plants and the ingredient for hemicellulose which makes up 30% of plants’ total mass. The current study uses glucose as reactant and evaluates hydrogen generation at different temperatures and different amounts of input flow of glucose – water mixture. Hydrothermal gasification method is used for hydrogen generation in an open system with c...
abstract background: migraine is a primary headache disorder that affects the neurovascular system. recent studies have shown that consumption of some fatty acids such as omega‑3 fatty acids improves migraine symptoms. the aim of the present study is to assess the association between usual intake of fatty acids such as eicosapentaenoic acid (epa), docosahexaenoic acid (dha), and saturated fatty...
The role of endogenous histamine and H1, H2 and H3 central receptors on food intake in broiler chickenswas investigated. For this purpose, a probe was used to manipulate the concentration of endogenoushistamine by intracerebroventricular (ICV) injection of thioperamide, an H3 receptor antagonist, and R-α-methylhistamine, an H3 receptor agonist and subsequently the effects of brain histaminergic...
Introduction: The brain glutamate system plays a central role in response to stress. This study examines the effect of memantine (a NMDA glutamate receptor antagonist) on stress from plantar electrical shock in male NMRI mice (Pasture Institute, Iran), weighing 25-30 g (n=6/group). Methods: The nucleus accumbens was bilaterally cannulated in a group of animals, and seven days later, differen...
The health of habitants, living in un-fluoridated drinking water areas, can be endangered through fluoride intake from food, beverages, tooth paste and dentistry products. Fluoride is used in mouthwash, toothpaste, juice fruits, conserved foods and Teflon dishes. Water exposure to fluoride occurs through fertilizers, aluminum industries, insecticides, pesticides, herbicides and fungicides use...
