About 1% of the total RNA of cell lines producing murine leukemia virus is virus-specific RNA. About one-third of the virus-specific RNA is located within the nucleus. The size distribution of virus-specific RNA was determined before and after denaturation. Before denaturation, virus-specific RNA sequences sedimented as a heterogeneous population of RNA molecules, some of which sedimented very ...
background and aims: hepatitis c virus is one of the viral infections transmitted by blood transfusion. patients with thalassaemia frequently need blood transfusion and are in danger of hcv infection. in most cases of infection (85%) the virus evades the immune system and establishes a chronic infection that may lead to cirrhosis and liver carcinoma. liver is the main site of hcv replication hc...
Abstract : Foot and Mouth Disease is one of the important live stocks contagious viral disease caused by Aphtovirus genus , that is belong to family RNA virus picornaviride. The important characteristic of FMD virus is high mutation that give rise to diversity of Antigen in surface of Neutralizing proteins. For this reason FMD virus have 7 distinct serotype and many subtype. Vaccination is o...
We consider a new model which consists of DNA together with RNA. Here we assume that is from mammal or bird but RNA comes virus. To study thermodynamic properties this use methods statistical mechanics, namely, the theory Gibbs measures. these measures to describe phases (states) DNA-RNA system. Using Markov chain (corresponding measure) give conditions (on temperature) renaturation.
methods allplex gi-virus assay was developed to detect pathogens causing viral gastroenteritis, one of the major diseases caused by rna viruses. this one-step multiplex real-time polymerase chain reaction (pcr) based on the mudt technique permits simultaneous amplification and detection of target nucleic acids of norovirus gi, norovirus gii, rotavirus a, adenovirus f, astrovirus, and sapovirus ...
background : gb virus c (gbv-c) is a flavivirus that was characterized in 1995. the prevalence of gbv-c rna in hiv-infected subjects has not been previously studied in iran and was therefore determined. methods: we have investigated serum samples of 80 patients from imam khomeini hospital, tehran, iran, whose hiv infection was confirmed in our laboratory by western-blotting. we used nested-pc...
Background and Aims: Virus-Induced Gene Silencing (VIGS) is a virus vector technology that exploits antiviral defense mechanism. By infecting plants with recombinant viruses containing host genes inserted in the viral genome, VIGS achieves the RNA silencing process. The purpose of this study was to investigate the possibility of tomato (Lycopersicon esculentum Mill.) and tobacco (Nicotiana be...
background the rate of mother-to-infant hepatitis c virus (hcv) transmission is relatively low, however, this mode of infection is the most important route for childhood hcv involvement. the chances of transmission are increased by the level of maternal hcv viraemia and maternal human immunodeficiency virus (hiv) co infection. objectives the objective of the present study was to determine the p...
The genomic RNA of 6/94 virus, an agent isolated from the brains of multiple sclerosis patients, was studied for sequence homology by RNA-RNA hybridization with closely related Sendai virus and another paramyxovirus virus, Newcastle disease virus. It was found that the genomic RNA of 6/94 virus hybridizes equally as well to the virus-specific 18S RNA found in Sendai-infected cells as that of Se...
