Growing evidence indicates that the endocannabinoid system is important for the acquisition and/or extinction of learning and memory. However, it is unclear which endocannabinoid(s) play(s) a crucial role in these cognitive functions, especially memory extinction. To elucidate the physiological role of 2-arachidonoylglycerol (2-AG), a major endocannabinoid, in behavioral and cognitive functions...
در کار اول؛ یک روش ساده، حساس، گزینش پذیر، دقیق و مقرون به صرفه برای اندازه گیری اسپکتروفتومتری کارودیلول در نمونه های دارویی و ادرار توسعه داده شد. روش بر اساس واکنش بین کارودیلول و نیتریت است. عوامل موثر بر واکنش، حجم واکنشگرهایی مانند هیدروکلریک اسید، نیتریت و سدیم هیدروکسید بود. متغیرها با استفاده از طراحی ترکیب مرکزی بهینه شدند. تحت شرایط بهینه، دو منحنی کالیبراسیون در گستره های غلظتی mgl^...
The present study was carried out to study the effect of different dosages of β-glucan suspension on immune response and disease resistance in Anabas testudineus spawns against a fungal pathogen Saprolegnia parasitica. Eight day old spawns were exposed for 3 h in four different dosages of β-glucan suspension in phosphate buffered saline at the rate of 0, 5, 10, 15 mg l(-1). The cell suspension ...
humic acid as an organic substance can bound heavy metals. it is a best way of decreasing the hazardous effect of heavy metals on plants and thereby on humans. a factorial experiment was conducted in a completely randomized design of seven replications. the treatments consisted of three cadmium levels (0, 2 and 4 mgl-1), and three humic acid levels (0, 100, 1000 mgl-1) added to nutrient solutio...
malathion (s-(1, 2-dicarboethoxyethyl) o, o-dimethyl phosphorodithioate) is one of the organophosphate pesticides comprehensively used in agriculture fields throughout the world. in spite of widely used, little information are available about dna damage in aquatic organisms. therefore, the present study carried out to investigation of dna damage induced by malathion in cyprinus carpio (pisces: ...
A simple and efficient protocol for recurrent somatic embryogenesis and plant regeneration is one of the prerequisites for genetic improvement of guava. An efficient reproducible regeneration somatic embryogenesis protocol was developed in four genotypes of Psidium guajava L. using immature zygotic embryo as starter explant. Somatic embryogenesis induction was obtained on MS basal medium supple...
Mg deficiency is considered as a risk factor of cardiovascular disorders like hypertension and atherosclerosis. MGH and MGL mice, selected for high and low Mg status, are animal models which present variations of Mg metabolism of genetic origin. The cardiovascular functions of these mice have never been studied. In this study, the arterial blood pressure of MGH and MGL strains was measured by p...
In this research, a new cost-effective carbon source of medium was provided in terms high-efficiency growth from Arthrospira maxima. Sugarcane molasses used two different modes (alternative and additive) at four concentrations (0, 0.5, 1.0 1.5 gL-1) to determine the effect versus its standard Zarrouk’s (NaHCO3). The experimental results were analyzed by Taguchi L8 method as statistical techniqu...
Background & Aim: Effects of ultra violet spectrum on plants due to their obligatory requirement for sunlight for survival are unavoidable. Direct effects of UV on plant growth and development are generally negative and usually they use many different defense mechanisms to acclimate and protect themselves. Material & Methods: The present research for the first time was conducted to investigate...
Cucumis melo L. is one of the most economically important horticultural crops worldwide. However, low plant regeneration frequency of this plant during genetic transformation is the major hurdle for applying biotechnological approaches. Hence, this study aimed to evaluate the effect of 6-benzyladenine (BA), cefotaxime (CTX), kanamycin (KAN), and indole-3-acetic acid (IAA) on the regenerati...
