The National Library of Medicine (NLM), on the campus of the National Institutes of Health in Bethesda, Maryland, is the world's largest medical library. The Library collects materials and provides information and research services in all areas of biomedicine and health care.
1) The process of joining two complementary strands of DNA or one each of DNA and RNA to form a double- stranded molecule.
2) Hybridization is the process of combining two complementary single-stranded DNA or RNA molecules and allowing them to form a single double-stranded molecule through base pairing. In a reversal of this process, a double-stranded DNA (or RNA, or DNA/RNA) molecule can be heated to break the base pairing and separate the two strands. Hybridization is a part of many important laboratory techniques such as polymerase chain reaction and Southern blotting.

1) The process of segregating, elaborating, and releasing some material either functionally specialized (as saliva) or isolated for excretion (as urine).
2) A product of secretion formed by an animal or plant; especially: one performing a specific useful function in the organism.
Industry:Health care
1) The process which spontaneously arrests the flow of blood from vessels carrying blood under pressure. It is accomplished by contraction of the vessels, adhesion and aggregation of formed blood elements, and the process of blood or plasma coagulation.
2) Stoppage or sluggishness of blood flow.
3) The arrest of bleeding (as by a hemostatic agent).

Industry:Health care
1) The proportion of individuals with a mutation causing a particular disorder who exhibit clinical symptoms of that disorder; a condition (most commonly inherited in an autosomal dominant manner) is said to have complete penetrance if clinical symptoms are present in all individuals who have the disease-causing mutation, and to have reduced or incomplete penetrance if clinical symptoms are not always present in individuals who have the disease-causing mutation.
2) A term indicating the likelihood that a given gene will actually result in disease.
3) The probability of a gene or genetic trait being expressed. "Complete" penetrance means the gene or genes for a trait are expressed in all the population who have the genes. "Incomplete" penetrance means the genetic trait is expressed in only part of the population. The percent penetrance also may change with the age range of the population.

1) The protein complement of an organism coded for by its genome.
2) In its most basic sense the term proteome refer to the total protein-encoding capability of an organism's genome. In use it is also used to refer to the actual total expressed protein complement of an organism or to the identifiable proteins of a single tissue or cell type or subcellular compartment.
3) The Proteome is the protein complement expressed by a genome. While the genome is static, the proteome continually changes in response to external and internal events.
Industry:Health care
1) The quality or state of being plastic; especially: capacity for being molded or altered.
2) The ability to retain a shape attained by pressure deformation.
3) The capacity of organisms with the same genotype to vary in developmental pattern, in phenotype, or in behavior according to varying environmental conditions.
4) The capacity for continuous alteration of the neural pathways and synapses of the living brain and nervous system in response to experience or injury that involves the formation of new pathways and synapses and the elimination or modification of existing ones.
Industry:Health care
1) The region of the stomach at the junction with the duodenum. It is marked by the thickening of circular muscle layers forming the pyloric sphincter to control the opening and closure of the lumen.
2) The opening from the vertebrate stomach into the intestine.
Industry:Health care
1) The regular recurrence, in cycles of about 24 hours, of biological processes or activities, such as sensitivity to drugs and stimuli, hormone secretion, sleeping, feeding, etc. This rhythm seems to be set by a 'biological clock' which seems to be set by recurring daylight and darkness.
2) Rhythmic recurrences of certain phenomena in living organisms occurring at about the same time of day, i.e., on a 24 hour cycle.
Industry:Health care
1) The relationships of groups of organisms as reflected by their genetic makeup.
2) The evolutionary history of a kind of organism.
3) The evolution of a genetically related group of organisms as distinguished from the development of the individual organism -- called also phylogenesis.
