Background and Aims: The hepatitis C virus (HCV) F protein is a recently described, frameshift product of HCV core encoding sequence. Its function and antigenic properties are unknown. In order to assess the presence of antibodies specific for F protein we characterized specific anti-F antibodies in patients with chronic HCV infection. Methods: The F protein was cloned from the HCV genome....
background: the purpose of this comparative study was to detect superoxide dismutase (sod) activities in fasciola hepatica, f. gigantica parasites, infected and healthy liver tissues in order to determine of species effects and liver infection on sods activity level. methods: fasciola spp. parasites and sheep liver tissues (healthy and infected liver tissues), 10 samples for each, were collecte...
background and aims: ndv (newcastle disease virus) is one of the viruses that cause disease in avian with severe economic losses in the poultry industry in many countries. fusion protein (f) which plays a major role in the virus pathogenicity contains several regions that have a role in the fusion process. mutation in the sequence of hr1 & hr2 regions of this protein prevents fusion of the viru...
background and aims: newcastle disease virus (ndv) is one of the major pathogen in poultry. vaccination is intended to control the disease as an effective solution nevertheless this virus is a growing threat to the poultry industry. f gene open reading frame (orf) from ndv is 1650 bp, encoding a protein of 553 amino acids that can induce protective immunity alone. the f glycoprotein on the surf...
بررسی بیان ژنهای دخیل در سیستم دفاعی گندم نسبت به mycosphaerella graminicola با استفاده از cdna-aflp
aflp یک ابزار قدرتمند برای تشخیص رونوشت هایی با فراوانی کم است و می تواند بعنوان یک روش کارآمد برای جداسازی ژنهایی که بطور متمایز بیان می شوند، بکار رود. بنابراین القا متمایز ژنها در گندم ( رقم چمران و مرودشت) در پاسخ به قارچ m.graminicola بوسیله آنالیز cdna-aflp مورد مطالعه قرار گرفت . در ابتدا گیاهان بوسیله بیمارگر مایه زنی شدند. نمونه برداری در 6 نقطه زمانی(0، 12، 24، 48، 72 و 96 ساعت) بعد ا...
An experiment was carried out to evaluate how interactions between forage to concentrate ratio and dietary crude protein level may alter nitrogen efficiency and UT-B expression in growing Baluchi male lambs. Four Baluchi male lambs [30 ± 2 kg BW] were used in a 4 × 4 latin square design with 28-d periods and a 2 × 2 factorial arrangement of dietary treatments. The treatments fed forage: concent...
