Abstract Background Human noroviruses are one of the main causes foodborne illnesses and represent a serious public health concern. Rapid sensitive assays for human norovirus detection undoubtedly necessary clinical diagnosis, especially in regions without more sophisticated equipment. Method The rapid reverse transcription recombinase-aided amplification (RT-RAA) is fast, robust isothermal nuc...
this study focuses on jane austens representation of her heroines in two of her novels: pride and prejudice, and mansfield park. i have concentrated only on a single idea: how jane austen takes her heroines through a course of psychogical reformation to which almost everything else in her novel is subsidiary. although i have discussed only pride and prejudice, we can trace austens carefully pla...
rivers and runoff have always been of interest to human beings. in order to make use of the proper water resources, human societies, industrial and agricultural centers, etc. have usually been established near rivers. as the time goes on, these societies developed, and therefore water resources were extracted more and more. consequently, conditions of water quality of the rivers experienced rap...
Abstract Background We aimed to investigate the association of initial chest CT scan findings with status and adverse outcomes COVID-19 (including ICU admission, mortality, disease severity). This retrospective cohort study was performed in three hospitals Babol, northern Iran, between February March 2020. Cases were confirmed by real-time polymerase chain reaction (RT-PCR). Clinical paraclinic...
Laboratory testing for dengue virus is used to confirm the diagnosis of dengue virus infection and to differentiate dengue from other febrile tropical illnesses. There are few data on the clinical use of reverse transcription-polymerase chain reaction (RT-PCR) for diagnosis of dengue virus infection. We prospectively evaluated 121 consecutive patients with possible dengue who had samples submit...
there is less published research about how teachers in efl contexts respond to students who are relatively less mature and less competent l2 writers. while writing researchers have examined various issues concerning peer and teacher response in writing-oriented classes, little research has centered on the effect of collaborative tasks particularly dictogloss on writing skills. output collaborat...
This report describes the clinical evaluation of a novel fluorescent immunoassay (FIA), Sofia Influenza A+B FIA (Quidel, San Diego, CA), for the rapid detection and differentiation of influenza A and B viruses. A total of 2,047 subjects provided nasal swabs and nasopharyngeal swabs or aspirates. The overall sensitivity and specificity for influenza A virus vs virus culture were 94% and 95%, res...
abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
The citrus systemic diseases, including Huanglongbing (caused by Candidatus Liberibacter asiaticus (CLas)), tristeza virus (CTV)), tatter leaf (CTLV)), and exocortis viroid (CEVd)), are threats to production in Taiwan. Reliable diagnostic methods important for the management of these diseases. In this study, we developed a multiplex reverse transcription–polymerase chain reaction (RT-PCR) assay...
Avian influenza virus (AIV) infection is a major cause of bird or human mortality and morbidity, therefore the rapid identification of the virus is of important clinical and epidemiological implication. Methods: A multiplex Reverse Transcriptase PCR (RT-PCR) was optimized for the detection of influenza A virus and the H5 and H9 subtypes. The influenza type A specific primers were directed to t...
