Abstract Rice stripe virus (RSV) is one of the most important viral pathogens rice in East Asia. The transcription RSV initiated by cap-snatching, a mechanism shared influenza (IFV). This lends possibility that antiviral compounds targeting cap-snatching IFV, many which have been commercially available, may inhibit transcription. A convenient and inexpensive system allowing researchers to test ...

The article describes a polymerase chain reaction (PCR) based method for semiquantitative assessment of mRNA expression for chemotactic cytokines in the lower respiratory tract cells. Cytokine mRNA was detected using PCR preceded by reverse transcription of mRNA into cDNA. The procedures of RNA extraction and of reverse transcription-PCR assay are described in the first part of the article. The...

It is widely known that cells from epithelial tumors, e.g., breast cancer, detach from their primary tissue and enter blood circulation. We show that the presence of circulating tumor cells (CTCs) in samples of patients with primary and metastatic breast cancer can be detected with an array of selected tumor-marker-genes by reverse transcription real-time PCR. The focus of the presented work is...

Background and Aims: Crimean-Congo hemorrhagic fever (CCHF) is a zoonosis caused by a Nairovirus of the family Bunyaviridae. Infection is transmitted to humans mostly by Hyalomma ticks. This study was conducted to determine the rate of CCHFV infection in ticks in Qom province of Iran. Materials and Methods: In this study, Reverse transcription – polymerase chain reaction (RT-PCR) was used...

A reverse transcription polymerase chain reaction (RT-PCR) based protocol with a pair of potato virus Y coat protein gene specific primers was found to be more sensitive method for the PVY detection in infected tobacco leaf and potato tuber tissues than conventional enzyme linked immunosorbent assay (ELISA) or nucleic acid spot hybridization (NASH) based methods. It was found in our studies tha...

The aim of this study was to provide information on the molecular characteristic and the phylogenic relationship of infectious bronchitis viruses (IBV) strains in Bushehr province in comparison to other strains reported in the Middle East. Samples were collected from broiler flocks in Bushehr province during 2014 - 2015. These flocks had respiratory problems such as gasping, sneezing and bronch...
