Background and Aims: Influenza virus is a major pathogen involved in respiratory illnesses during winter seasons. A variety of diagnostic methods have been developed to identify influenza viruses in clinical specimen. Methods: Nasal and pharyngeal samples taken from patients were inoculated into Madin-Darby canine kidney (MOCK) cells and embryonated chicken eggs (ECEs). The culture media was a...
Background: In the current COVID-19 pandemic, there is a rising need for a rapid and reliable diagnostic tool. We hypothesized that chest computed tomography (CT) can be a potential alternative for reverse transcription-polymerase chain reaction (RT-PCR). The aim of this study was to compare the diagnostic value of chest CT and RT-PCR in Iranian patients with suspected COVID-19. Methods: In a...
The present study was undertaken to analyze the expression pattern of estrogen receptor 1 gene (ESR1) in Barbari bucks (fertile and non-fertile) identified on the basis of seminal quality traits and fertility trials. RNA was extracted from the spleen by Trizol method. The expression pattern of ESR1 gene was analyzed using real time polymerase chain reaction (RT-PCR). The expression pattern of E...
Background: Recombinant tissue plasminogen activator (rt-PA) is one of the most important thrombolytic agentsused in patients with vascular occlusions such as acute ischemic stroke or myocardial infarction. A variety of recombinant protein expression systems have been developed for heterologous gene expression in prokaryotic and eukaryotic hosts. In recent years, Leishmania tarentolae (L. tare...
background: generally, sewage exposed water could be potentially contaminated with enteroviruses. for this reason, enterovirus isolation from sewage specimens is one of the most sensitive indicators for virus circulation in the population. we evaluated the icc-rt-pcr and cell culture methods for detection of enteroviruses in tehran sewage system. methods: this research utilized 63 specimens p...
