The present research tests limitedand unlimited-capacity theories of perception by comparing accuracy in detection and search tasks under conditions of simultaneous and successive presentation of array items. The unlimited-capacity approach predicts no difference between simultaneous and successive presentation when nonperceptual factors are controlled. The limitedcapacity approach predicts an ...

in the present study a new economic and rapid bacterial micro-assay for simultaneous detection and quantitative measurement of serum galactose was developed. analysis of the standard curve showed a linearity range for galactose from 2 mg/dl to 180 mg/dl with a regression equation of y = 0.013x ? 0.083; r² = 0.962. the advantage of the method is its ability to measure serum galactose quantitativ...

the net analyte signal standard addition method was used for simultaneous spectrophotometric determination of sertraline and fluoxetine in pharmaceutical preparations. the method combines the advantages of the standard addition method with the net analyte signal concept to enable the extraction of information about an analyte from the spectra of multi-component mixtures. this method uses full s...

Evidences from many studies suggested a polymerase chain reaction (PCR) as a valuable method for diagnosing infectious disease in the transplant recipients. We used this method for detection of Toxoplasma, gondii and human cytomegalovirus in blood specimens from patients after bone marrow or kidney transplantation. DNA of both infectious agents were detected using two separate sets of nested pr...

Single-cell metabolomics can be used to study cell diversity and how cells respond to environment. There is an urgent need to develop effective detection methods for single-cell metabolomics. Microchip electrophoresis with laser-induced fluorescence detection (MCE-LIFD) is a powerful tool to detect metabolites at the single-cell level. However, the existing one-laser excitation and one-color fl...

Electroanalysis was performed using a boron-doped diamond (BDD) electrode for the simultaneous detection of 2-heptyl-3-hydroxy-4-quinolone (PQS), 2-heptyl-4-hydroxyquinoline (HHQ) and pyocyanin (PYO). PQS and its precursor HHQ are two important signal molecules produced by Pseudomonas aeruginosa, while PYO is a redox active toxin involved in virulence and pathogenesis. This Gram-negative and op...

We extended the concept of fluorescent microsatellite genotyping with a single-universal tailed primer to the simultaneous use of three different tailed primers to allow multiplexed 4-color detection for medium throughput genotyping of plant species. The method was tested on Eucalyptus DNA samples using three forward primer sequences of human microsatellite markers labeled with different fluore...

A novel magnetobiosensing approach for the rapid and simultaneous detection of two breast cancer-related miRs (miR-21 and miR-205) is reported. It involves the use of antimiR-21 and antimiR-205 specific probes, chitin-modified magnetic beads (Chitin-MBs), the p19 viral protein as capture bioreceptor and amperometric detection with the H2O2/hydroquinone (HQ) system at dual screen-printed carbon ...
