background: the h9n2 subtype of avian influenzaviruses (aivs) have spread in asia and middle east countriesand have become a serious threat to poultry industry in iran.objectives:characterization of genes of h9n2 subtype involvingin pathogenicity and diagnosis are crucial in control of avianinfluenza outbreaks. the nonstructural (ns) gene and its proteinproducts (ns1 & ns2) are important as...
Exceeded losses of nonstructural components from structural ones in most demolished buildings in previous earthquakes and its limitation on functionality of critical facilities and building serviceability after earthquakes should be got the point of view for accounting loss of building as a merit for building performance. This paper attempts to demonstrate the significant role of distribution p...
By the end of 2004, more than 20 HIV-1 vaccine candidates will have entered clinical testing in at least 30 trials worldwide. Almost half of these vaccines include nonstructural HIV-1 gene products. This represents an important innovation in the HIV vaccine field, because until 9 years ago not even preclinical testing in small animal models had been carried out with such immunogens. This review...
Most of the seven flavivirus nonstructural proteins (NS1 to NS5) encoded in the distal two-thirds of the RNA positive-sense genome are believed to be essential components of RNA replication complexes. To explore the functional relationships of these components in RNA replication, we used trans-complementation analysis of full-length infectious RNAs of Kunjin (KUN) virus with a range of lethal i...
PML nuclear bodies and their associated functions are part of an intrinsic cellular mechanism aimed at maintaining transcriptional control over viral gene expression and preventing replication of invading viruses. To overcome these barriers, many viruses express early nonstructural, multifunctional proteins to support the viral replication cycle or modulate host immune responses. Virion protein...
background: hospitals in iran are not prepared for disasters the aim of this study was to determine the effect of training functional and nonstructural hospital safety to nurses and their intervention on hospital preparedness in psychiatric razi hospital and day hospital in tehran based on hospital safety index (hsi). materials and methods: this semi-experimental study included nurse ma...

Background:Potyvirus-based virus-induced gene silencing (VIGS) is used for knocking down the expression of a target gene in numerous plant species. Sugarcane mosaic virus (SCMV) is a monopartite, positive single strand RNA virus. Objectives:pBINTRA6 vector was modified by inserting a gene segment of SCMV in place of Tobacco rattle virus (TRV) genome part 1 (TRV1 or RNA1)...
aim : we aimed to investigate the prevalence of human bocavirus isolates among iranian patients suffering from acute gastroenteritis. background : human bocavirus is a new parvovirus that has been identified in association with gastroenteritis. limited data are available about hbov in iran. patients and methods : viral dna was extracted from all 294 stool samples. hbov dna was detected in extra...
The orphan parvovirus tumor virus X (TVX) has potent oncolytic activity. Compared to other viruses from the species Rodent protoparvovirus 1, TVX has a 111 nucleotide deletion in its nonstructural (NS) gene, a 24 nucleotide insertion in VP1, and a 93 nucleotide repeat initiating from the C-terminus of the capsid gene.
