Glossary Term
The act of validating; finding or testing the truth of something.
Indicators
A synthetic derivative of propylpentanoic acid with antiepileptic properties and potential antineoplastic and antiangiogenesis activities. In epilepsy, valproic acid appears to act by increasing the concentration of gamma-aminobutyric acid (GABA) in the brain. This agent's antitumor and antiangiogenesis activities may be related to the inhibition of histone deacetylases and nitric oxide synthase, which results in the inhibition of nitric oxide synthesis. (NCI04)
Indicators
A branched tricyclic glycosylated peptide with bactericidal activity against most organisms and bacteriostatic effect on enterococci. At a site different from that of penicillins and cephalosporins, vancomycin binds tightly to the D-alanyl-D-alanine portion of cell wall precursors, thereby interfering with bacterial cell wall synthesis. This leads to activation of bacterial autolysins that destroy the cell wall by lysis. Vancomycin may also alter the permeability of bacterial cytoplasmic membranes and may selectively inhibit RNA synthesis.
Tests
The determination of the amount of organisms that are vancomycin-resistant, and are not assigned to the species level but are assigned to the Enterococcus genus level in a biological sample.
Glossary Term
A measure of the variability in a sample or population. It is calculated as the mean squared deviation (MSD) of the individual values from their common mean. In calculating the MSD, the divisor n is commonly used for a population variance and the divisor n-1 for a sample variance.
Glossary Term
The relative rate of occurrence of a specific variant allele compared to the total number of alleles at that locus in the sample. This measurement may be reported as a ratio or percentage.
Glossary Term
An alteration or difference from a norm or standard.
Tests
The determination of the amount of Varicella Zoster virus DNA in a biological sample.
Indicators
Vascular endothelial growth factor A (232 aa, ~27 kDa) is encoded by the human VEGFA gene. This protein plays a role in both cell proliferation and angiogenesis.
Tests
The determination of the amount of vascular epithelial growth factor present in a sample.
Tests
The determination of the amount of Vibrio cholerae DNA present in a sample.
