West Nile virus (WNV) causes a severe zoonosis, which can lead to a large number of casualties and considerable economic losses. A rapid and accurate identification method for WNV for use in field laboratories is urgently needed. Here, a method utilizing reverse transcription loop-mediated isothermal amplification combined with a vertical flow visualization strip (RT-LAMP-VF) was developed to d...

watermelon mosaic virus is the most prevalent potyvirus infecting cucurbits in iran. in order to determine the distribution and frequency of the virus, 326 watermelon, melon, cucumber, winter and summer squash samples were collected from 22 villages around urmia during summer 2010 and tested by das-elisa with a polyclonal antibody. ninety four samples were detected as infected by elisa. to dete...

Most mumps patients are clinically diagnosed without any virological examinations, but some diagnosed cases of mumps may be caused by other pathogens or secondary vaccine failure (SVF). To clarify these issues, a sensitive, specific, and rapid diagnostic method is required. We obtained 60 salivary swabs from 34 patients with natural infection during the course of the illness, 10 samples from pa...

Nine long-chain phenols: four cardanols (1-4), two bilobols (5, 6) and three alkylsalicylic acids (7-9) [corrected] were isolated from the CH(2)Cl(2) extracts of the sarcotestas of Ginkgo biloba as HIV-1 protease (PR) inhibitors. From these phenols, the bilobols (IC (50), 2.6 - 5.8 microM) and alkylsalicylic acids (IC (50), 10.2 - 24.9 microM) exhibited dose-dependent potent inhibitory activiti...

Introduction. Polymerase chain reaction (PCR)-based diagnostic tests use purifi ed nucleic acids (NAs) from clinical samples. The NAs cation step adds time, cost, and aff ects the quality of testing. objective this study was to develop a protocol for direct saliva in genetic markers, without acids. Methods. PCR, real-time RT-PCR isothermal amplifi were used detection Results. We report markers ...

This study was carried out in bean seeds Isparta and Antalya provinces to determine Bean common mosaic virus (BCMV) 2016. For this purpose; 106 seed samples were collected from the research area. Seed used for biological, serological, molecular methods. The incidence, as a percentage of BCMV, found 87.73% by DAS-ELISA 90.56% Immunocapture Reverse Transcriptase-Polymerase Chain Reaction (IC-RT-P...

Epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) has intracranial activity in EGFR-mutant Non-Small Cell Lung Cancer (NSCLC). The optimal timing of brain radiotherapy (RT) and appropriate patients who need early brain RT remains undetermined. This is a retrospective study of EGFR-mutant NSCLC patients with newly diagnosed brain metastases (BMs) before EGFR-TKI initiation. I...

Members of the tumor necrosis factor (TNF) superfamily have been revealed to be associated with painful bladder syndrome/interstitial cystitis (PBS/IC). TNF ligand-related molecule 1A (TL1A) and its receptor, death receptor 3 (DR3), belong to the TNF superfamily and have been implicated in chronic inflammatory diseases. Bladder biopsies from 8 female patients clinically diagnosed with PBS/IC ac...

The coronavirus disease 2019 (COVID-19) pandemic has highlighted bottlenecks in large-scale, frequent testing of populations for infections. Polymerase chain reaction (PCR)-based diagnostic tests are expensive, reliant on centralized labs, can take days to deliver results, and prone backlogs supply shortages. Antigen that bind detect the surface proteins a virus rapid scalable but suffer from h...

An epidemic of Chikungunya fever of unprecedented magnitude occurred in many parts of India in early 2006 after an interval of 33 years, and there has been a resurgence in some parts of South India since June 2007. The article highlights clinical manifestations of infection and various molecular tests that were used for diagnoses of Chikungunya virus infection. Of particular interest is the rea...
