Sambucus nigra (elder) are broadly used species to treat microbial infections. Thepotential antiviral activity and mechanism action of elder fruit (EF) in human epithelium cell(A549) cultures infected with H9N2 influenza virus were determined. The effect of variousconcentrations of EF on influenza virus replication was examined by using virus titration,quantitative real time RT-PCR, fusion and ...
Background and purpose: The need to find new antiviral compounds is increasing due to the emergence of resistant strains and toxicity of currently available HIV drugs. In this research the inhibitory activity of a number of novel iron chelating compounds derived from 3-Hydroxy-4-pyridinosnes was studied. Materials and methods: Single cycle replicable (SCR) virion was produced by transfection o...
Background and purpose: Adenoviruses and enteroviruses as intestinal viruses are detected in wastewater. Fecal shedding of 2019 novel coronavirus (SARS-CoV-2) has been reported in some studies. Therefore, determining the presence of these viruses in wastewater is important to maintain public health and helps in predicting and preventing viral infections in a community. Materials and methods: I...
Abstract Background and objectives: C-Met is a proto-oncogene that encodes a protein known as hepatocyte growth factor receptor (HGFR). The HGF receptor possesses tyrosine -kinase activity and it is essential for embryonic development, wound healing and cancer. Many proteins are proteolytically released from the surface by a process known as ectodomain shedding. Shedding occurs under normal phy...
Viral myocarditis is a moderate disease, but it sometimes causes progressive cardiac disorder. Many different viruses have been considered as the agent of viral myocarditis, but Coxsackievirus of the B group, in particular of the Coxsackievirus B3 (CVB3), is more than fifty percent of cases of viral myocarditis. CVB3 is a positive single-stranded RNA virus and a member of the genus Enterovirus ...
Infectious Pancreatic Necrosis Virus (IPNV) is a member of the family Birnaviridae that has been linked to high mortalities in salmonids. Bacterial based systems as live vectors for the delivery of heterologous antigens offer a number of advantages as vaccination strategies. VP2 is a structural viral protein of IPNV with immunogenicity effects. In this study IPNV was isolated from diseased fry ...
Background & Aims: Acute respiratory infections are common cause of mortality during childhood. This study was designed to determine the incidence of adenovirus, parainfluenza virus and respiratory syncytial virus in respiratory infections by Multiplex PCR method. Methods: This study included 168 children under 2 years of age with clinical diagnosis of bronchiolitis. Nasopharyngeal specimens we...
Background and Objective: Viral myocarditis (VMC) is one of the common heart diseases to endanger human health in different age groups, especially children. The aim of this study was to diagnose VMC in children with clinical suspicion of myocarditis (MCI) using multiplex real-time PCR in Birjand Vali-Asr Hospital. Methods: This cross-sectional study was conducted on 19 patients with clinical s...
