Glossary Term
The probability that a test will produce a true negative result when used on non-effected subjects as compared to a reference or "gold standard". The specificity of a test can be determined by calculating: number of true negative results divided by the sum of true negative results plus number of false positive results.
Pruebas
The determination of the amount of dibenzo[a,i]pyrene in a sample.
Indicadores
This gene is involved in the RNA interference pathway.
Glossary Term
A DNA sequencing technique in which a mixture of deoxynucleosidetriphosphates (dNTPs) and chain-terminating dNTPs, which are radioactively or fluorescently labeled, are combined within the reaction mixture. Once the reaction is complete, the DNA strands are separated by size, and the labeled chain terminating dNTPs can be read in sequence by the investigator or by a machine.
Pruebas
The determination of the naturally occurring folate in a nutritional product or meal, or a portion thereof.
Pruebas
A determination of the total refined grains in a nutritional product or meal, or a portion thereof.
Artículo
Research record from J Anal Toxicol, 2026-06-01. PMID 42377259.
Glossary Term
A type of polymerase chain reaction technique in which the sample is fractionated, within which individual PCR reactions occur in each fraction.
Indicadores
A cardiac glycoside. Digoxin inhibits the sodium potassium adenosine triphosphatase (ATPase) pump, thereby increasing intracellular calcium and enhancing cardiac contractility. This agent also acts directly on the atrioventricular node to suppress conduction, thereby slowing conduction velocity. Apparently due to its effects on intracellular calcium concentrations, digoxin induces apoptosis of tumor cells via a pathway involving mitochondrial cytochrome c and caspases 8 and 3. (NCI04)
Glossary Term
Any liquid or solid material used to lessen the strength or flavor of a solution or mixture of another ingredient.
Glossary Term
To reduce in strength or concentration, especially by the addition of water.
Pruebas
The determination of the amount of the biological activity of dipeptidyl peptidase-4 in a sample.
