Imputation as a method of creating low-density chips to high-density chips has been introduced to increase the accuracy of genomic selection in animals. In the current study, to investing imputation accuracy, three populations of mixed (scenario 1), pure (scenario 2) and mixed + pure (scenario 3) were simulated using QMSim. Two methods of imputation including Beagle and Flmpute were used fo...
The aim of this study was to investigate the effect of inbreeding on the estimation of genetic parameters of weight traits at different ages in Moghani sheep. In the present study, the information of 11721 Moghani sheep in Jafarabad Moghan breeding station from 1987 to 2011 was used. Genetic parameters were estimated using single trait model with covariate and classification and without inbree...
Background: Nandrolone decanoate (ND) is an anabolic androgenic steroid (AAS) which influences the ovarian structure and function. We assessed the effects of ND on the ovarian volume, number of primordial follicles, and level of hormones and also evaluated the modulatory effects of gonadotropins on the histopathological changes imposed by the administration of ND. Methods: Six groups of Sprague...
در این مقاله بیماری ایدز با تابلوی بالینی پیچیده خود معرفی خواهد شد. ویروس HIV یا نقص ایمنی انسانی، مانند سایر ویروس ها، جهت چرخه حیات و تولید مثل خود به محیط درونی سلول نیاز دارد. میزبانان HIV در بدن بطور عمده سلول های سیستم ایمنی شامل لنفوسیت های T، سلول های کمک کننده T و مونوسیت ها می باشند . ویروس بصورت مؤثر سلول ها را بکار گرفته و از آن ها به عنوان ماشینی جهت اجرای دستورات ژنتیکی خود استفا...
All farm animals will experience some level of stress during their lives. Stress reduces the fitness of an animal, which can be expressed through failure to achieve production performance standards, or through disease and death. Stress in farm animals can also have detrimental effects on the quality of food products. However, although a common assumption of a potential effect of stress on food ...
Background: Sponges and sea anemones do not have specialized defense organs. Instead, they rival harmful microorganisms by producing certain compounds. These compounds can also be useful against some human pathogens. This study aimed to investigate the antimicrobial effects of bioactive products from these marine animals. Methods: Two species of sea anemone <e...
The harmful use of alcohol causes an estimated 2.5 million deaths every year, of which a significant proportion occur in the young. Alcohol use is the third leading risk factor for poor health globally. In response to harmful use of alcohol, World Health Organization developed a global strategy to reduce the harmful use of alcohol endorsed by the Sixty-third World Health Assembly in 2010. Paral...
Background and aims: Survay of the particulates, biological molecules and other harmful materials which enter into Earth's atmosphere as airborn agents is one of research intrest of health sciences. Animal housing laboratories for producing malodor especially near residential, educational and official areas can cause neighbors complainant. In order to overcome this challenge qualitative and qua...
asymmetric polyethersulfone (pes) microfiltration flat sheet membranes were composed by the phase inversion method (pim) and were used as supports. composite membranes were fabricated by coating silicone rubber as selective layer. effect of different concentrations of pes and pdms and different solvent such as nmp, dmf and dms effects as pes solvents and support thickness and different coagulat...
