vaccines is considered as a critical point and in-process of quality control (ipqc) test of vaccine production. rapid tests, like real time pcr, are more appropriated when the production occurs at industrial scale because of the amounts of starting materials and the excess of consumed time required. in the current study, a real-time quantitative reverse transcription-polymerase chain reaction (...

conclusions this study showed that this novel one-step rrt-pcr assay is a rapid, reliable, repeatable, specific, sensitive, and simple tool for the detection of the cchf virus. results from a total of 75 suspected serum samples, 42 were confirmed to be positive for cchf virus, with no false-positives detected by the sequencing results. after 40 amplification cycles, the melting curve analysis r...

Researchers often statistically control for means when examining individual or age-associated differences in variances, assuming that the relation between the 2 is linear and invariant within and across individuals and age groups. We tested this assumption in the domain of working memory by applying variance-heterogeneity multilevel models to reaction times in the n-back task. Data are from the...

Mean reaction times (RT) and the intra-subject variability of RT in simple RT tasks have been shown to predict higher-order cognitive abilities measured with psychometric intelligence tests. To further explore this relationship and to examine its generalizability to a sub-adult-aged sample, we administered different choice RT tasks and Cattell’s Culture Fair Intelligence Test (CFT 20-R) to n = ...
