Pruebas
The determination of the surface antigen reaction of a biological specimen to the Hepatitis A virus.
Glossary Term
Having two different allelic forms of a gene, one inherited from each parent, on each of the two homologous chromosomes.
Indicadores
The smallest and densest lipoproteins, containing a high proportion of protein. They are synthesized in the liver as empty proteins and they pick up cholesterol and increase in size as they circulate through the bloodstream. Because HDL can remove cholesterol from the arteries, and transport it back to the liver for excretion, they are seen as "good" lipoproteins.
Pruebas
A chemiluminescence immunoassay capable of detecting very low levels of troponin T in serum.
Indicadores
A semi-essential amino acid (children should obtain it from food) needed in humans for growth and tissue repair, Histidine is important for maintenance of myelin sheaths that protect nerve cells and is metabolized to the neurotransmitter histamine. Histamines play many roles in immunity, gastric secretion, and sexual functions. Histidine is also required for blood cell manufacture and protects tissues against damage caused by radiation and heavy metals. (NCI04)
Pruebas
The determination of the number of mismatch between the study subject and his or her donor for the human leukocyte antigen, class I, group A (HLA-A).
Indicadores
This gene plays a role in both immune responses and histocompatibility processes.
Indicadores
This gene plays a role in both DNA binding and transcriptional modulation.
Glossary Term
Having two identical allelic forms of a gene, one inherited from each parent, on each of the two homologous chromosomes.
Indicadores
This gene plays a role in signal transduction and cellular communication.
Indicadores
A sialoglycoprotein hormone secreted by the placenta and maintains the corpus luteum at the beginning of the gestation period.
Glossary Term
The X or Y chromosome in human beings that determines the sex of an individual. Females have two X chromosomes in diploid cells; males have an X and a Y chromosome. The sex chromosomes comprise the 23rd chromosome pair in a human karyotype.
