APOBEC3 proteins can inhibit human immunodeficiency virus type 1 (HIV-1) replication by inducing G-to-A mutations in newly synthesized viral DNA. However, HIV-1 is able to overcome the antiretroviral activity of some of those enzymes by the viral protein Vif. We investigated the impact of different processivities of HIV-1 reverse transcriptases (RT) on the frequencies of G-to-A mutations introd...
during 2004-2006, a total number of 22 tissue samples obtained from poultry flocks suspected to respiratory diseases submitted to avian virology laboratory of faculty of veterinary medicine, were prepared for avian influenza virus (aiv) isolation in embryonated chicken eggs, according to the standard method. rt-pcr was established on tissue samples using specific primers for h9 gene. amplified ...
avian influenza (ai) is a viral respiratory disease of domestic and wild birds. in the diagnostic laboratory, it is essential to have methods for rapid detection of avian respiratory viruses. cloacal swabs collected from chickens experimentally infected with h9 subtype ai virus, used in a reverse transcription-polymerase chain reaction (rt-pcr) assay for detection of ai. in infected animals, ai...
Since Feb, 2013, more than 100 human beings had been infected with novel H7N9 avian influenza virus. As of May 2013, several H7N9 viruses had been found in retail live bird markets (LBMs) in Guangdong province of southern China where several human cases were confirmed later. However, the real avian influenza virus infection status especially H7N9 in Guangzhou remains unclear. Therefore, a cross...
HIV infection by sexual transmission remains an enormous global health concern. More than 1 million new infections among women occur annually. Microbicides represent a promising prevention strategy that women can easily control. Among emerging therapies, natural small molecules such as flavonoids are an important source of new active substances. In this study we report the in vitro cytotoxicity...
We previously described that immunopotentiators, CVCVA5, increased the efficacy of H5 and H9 subtype avian influenza vaccines in chickens, ducks, and geese. In this study, we further investigated the effects of the CVCVA5 for improving the efficacy of other univalent or multivalent inactivated vaccines. The immune response administrated with half-dose of monovalent vaccine plus CVCVA5 were high...
Our analyses of blood and urine samples from patients treated with gold-based antiarthritis drugs have shown that the dicyanogold(I) anion, [Au(CN)2]’, is a common metabolite. Previous work by Graham had suggested that [Au(CN)2]" would form as a result of interaction of any of the goldbased drugs with cyanide and that [Au(CN)2]" would be readily taken up by cells. Our own work with red blood ce...
از آنجاییکه rna پلی مراز ویروس آنفلوانزا، فاقد مکانیسم ویرایش و تصحیح اشتباهات احتمالی است، جهش در ویروس آنفلوانزا به فراوانی رخ می دهد. جهش می تواند منجر به تغییر آمینواسیدی در توالی یک پروتئین شود. ویروس آنفلوانزای تحت تیپ h9n2 در انسان و طیور می تواند بیماری ایجاد کند. شواهدی وجود دارد که تغییر در پپتیدهای اتصالی هماگلوتینین (ناحیه ی شکافت) می تواند منجر به ایجاد ویروس آنفلوانزایh9n2 بسیار ب...
Anti-myosin Abs are associated with inflammatory heart diseases such as rheumatic carditis and myocarditis. In this study, human cross-reactive anti-streptococcal/anti-myosin mAbs 1.C8, 1.H9, 5.G3, and 3.B6, produced from peripheral blood lymphocytes of patients with rheumatic carditis, and mAb 10.2.5, produced from a tonsil, were characterized, and the nucleotide sequences of their V(H) and V(...
