Rapid antigen and antibody, serological tests, and RT ‑ PCR-based molecular methods are widely used for the detection of microorganisms worldwide. Objectives: This study aimed by Isothermal nucleic acid amplification techniques to detect the covid-19. Methods: In this study, 200 samples of nasopharynx and oropharynx were collected from Jamaran Heart Hospital in Tehran. Covid -19 was exami...

The present study assesses central processing of subjective appraisal, expectancy, orientation and reaction time as indexed by Contingent Negative variation (CNV) response in chronic pain patients. Waves N1, P3 and CNV were recorded during a CNV paradigm in a simple reaction time task with a constant interstimulus interval (ISI) of 1 sec. CNV was measured from CZ x FZ in controls and chronic pa...

Molecular techniques based on the detection of genomic sequences by reverse transcription (RT)-PCR, nested PCR, or real-time PCR have made possible the rapid diagnosis of dengue virus (DENV) infections, and these approaches have been accepted by clinical laboratories as the new standard method for the detection of dengue virus in acute-phase serum samples. One of these PCR-based assays, the two...

To assess the performance of second reading chest compute tomography (CT) examinations by expert radiologists in patients with discordance between reverse transcription real-time fluorescence polymerase chain reaction (RT-PCR) test for COVID-19 viral pneumonia and CT report. Three hundred seventy-eight were included this retrospective study (121 women 257 men; 71 years median age, a range 29–93...

OBJECTIVE Psychomotor vigilance testing (PVT) rapidly assesses attention, reaction time (RT), and abnormal vigilance. Thus, PVT may be an adjunct to screening drivers for high-risk obstructive sleep apnea (OSA)/excess daytime sleepiness (EDS). METHODS Commercial drivers and emergency responders undergoing occupational examinations took a 10-minute PVT and were instructed to achieve their fast...

[Purpose] The aim of this study was to investigate the immediate effect of Lokomat versus Ergo_bike training using the Probe Reaction Time (P-RT) and 10-m maximum walking speed as the outcome measures, on incomplete spinal cord injury (iSCI) patients. [Subjects] Thirty male T8-L3 level spinal cord injury patients were the subjects. [Methods] The subjects were randomly divided into 2 groups: a L...

Real-time reverse transcription polymerase chain reaction (RT-PCR) tests for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are occasionally repeated when clinicians suspect false-negative results, but the conditions under which RT-PCR testing is warranted remain unclear. We evaluated practice of repeat SARS-CoV-2 in 45 patients who were retested after an initial negative PCR test...
