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.
Densely staining chromatin that appears as nodules in or along chromosomes and contains relatively few genes.

1)The virus isolated and recognized as the etiologic agent of AIDS. HIV-1 is classified as a lentivirus, a subtype of retroviruses.
2) Human immunodeficiency virus, the cause of acquired immunodeficiency syndrome (AIDS).
3) Any of several retroviruses and especially HIV-1 that infect and destroy helper T cells of the immune system causing the marked reduction in their numbers that is diagnostic of AIDS -- called also AIDS virus.
Industry:Medical
1) Ingestion of a greater than optimal quantity of food.
2) Abnormally increased appetite for food frequently associated with injury to the hypothalamus.
Industry:Medical
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. 2: The arrest of bleeding (as by a hemostatic agent. )
Industry:Medical
1) Polypeptide that is secreted by the anterior pituitary gland; affects protein, carbohydrate and lipid metabolism; stimulates mitosis, cell differentiation and cell growth.
2) A peptide hormone secreted by the anterior lobe of the pituitary gland and regulates several physiologic processes, including growth and metabolism.
Industry:Medical
1) Any member of the class of enzymes that catalyze the cleavage of the substrate and the addition of water to the resulting molecules, e.g., esterases, glycosidases (glycoside hydrolases), lipases, nucleotidases, peptidases (peptide hydrolases), and phosphatases (phosphoric monoester hydrolases).
2) Enzymes (EC class 3) cleaving substrates with addition of H2O at the point of cleavage; e.g., esterases, phosphatases, nucleases, peptidases.
Industry:Medical
1) A haplotype is a set of DNA variations, or polymorphisms, that tend to be inherited together. A haplotype can refer to a combination of alleles or to a set of single nucleotide polymorphisms (SNPs) found on the same chromosome. Information about haplotypes is being collected by the International HapMap Project and is used to investigate the influence of genes on disease.
2) A group of alleles of different genes (as of the major histocompatibility complex) on a single chromosome that are closely enough linked to be inherited usually as a unit.
Industry:Medical
1) A relatively small nodular inflammatory lesion containing grouped mononuclear phagocytes, caused by infectious and noninfectious agents.
2) A mass or nodule of chronically inflamed tissue with granulations that is usually associated with an infective process.
