Pruebas
A measurement of the complement required to lyse 50 percent of red blood cells in a biological specimen.
Indicadores
This gene plays a role in cell survival and the negative regulation of cell growth.
Pruebas
A laboratory test designed for the quantification of an organic or inorganic chemical within a biological specimen.
Glossary Term
Chi-square test is a statistical test for testing the null hypothesis that the distribution of a discrete random variable coincides with a given distribution. It is one of the most popular goodness-of-fit tests.
Artículo
Research record from Braz J Med Biol Res, 2026-08-21. PMID 42659460.
Indicadores
A chlorine anion that forms the negatively charged part of certain salts, including sodium and hydrogen chloride salts, and is an essential electrolyte located in all body fluids responsible for maintaining acid/base balance, transmitting nerve impulses and regulating fluid in and out of cells.
Indicadores
Chromogranin-A (457 aa, ~51 kDa) is encoded by the human CHGA gene. This protein plays a role in the modulation of both blood pressure and pancreatic release of insulin.
Glossary Term
A structure found in cells that is comprised of a strand of linearized double-stranded DNA plus proteins that package the DNA in a condensed coil form and regulate chromosomal function.
Glossary Term
A sequence of single-stranded RNA that forms a covalently closed continuous loop.
Indicadores
A tricarboxylic acid found in citrus fruits. Citric acid is used as an excipient in pharmaceutical preparations due to its antioxidant properties. It maintains stability of active ingredients and is used as a preservative. It is also used as an acidulant to control pH and acts as an anticoagulant by chelating calcium in blood.
Indicadores
A non-essential amino acid. In hepatocytes, L-citrulline is synthesized in the urea cycle by the addition of carbon dioxide and ammonia to ornithine. L-citrulline is converted into L-arginine by the enzymes argininosuccinate synthetase and argininosuccinate lyase in the presence of L-aspartate and ATP. Subsequently, L-arginine is converted to nitric oxide by nitric oxide synthase and L-citrulline is regenerated as a by-product.
