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) Shock-like contraction of a portion of a muscle, an entire muscle, or a group of muscles; may be part of a disease process or a normal physiological response.
2) Irregular involuntary contraction of a muscle usually resulting from functional disorder of controlling motor neurons; also: a condition characterized by myoclonus.

1) Short tracts of DNA sequence that are used as landmarks in genome mapping. In most instances, 200 to 500 base pairs of sequence define a Sequence Tagged Site (STS) that is operationally unique in the human genome (i.e., can be specifically detected by the polymerase chain reaction in the presence of all other genomic sequences). The overwhelming advantage of STSs over mapping landmarks defined in other ways is that the means of testing for the presence of a particular STS can be completely described as information in a database.
2) Short, single-copy, genomic DNA sequences spaced at intervals of about 100 kb, used as landmarks to identify the physical origin (chromosomal position) of any clone (gene) of interest; touted as the new "lingua franca" of genome mapping.

1) Signal molecules that are involved in the control of cell growth and differentiation.
2) Substances made by the body that function to regulate cell division and cell survival. Some growth factors are also produced in the laboratory and used in biological therapy.

1) Simple sugars, carbohydrates which cannot be decomposed by hydrolysis. They are colorless crystalline substances with a sweet taste and have the same general formula CnH2nOn. (From Dorland, 28th ed)
2) A sugar not decomposable to simpler sugars by hydrolysis -- called also simple sugar.

1) Sister chromatids are the two newly synthesized daughter chromatids derived from the same chromosome parent. During chromosomal pairing in meiosis, recombination can occur between sister or non-sister chromatids.
2) Any of the chromatids formed by replication of one chromosome during interphase of the cell cycle especially while they are still joined by a centromere.

1) Situation in which two different alleles for a genetic trait are both expressed.
2) Codominance is a relationship between two versions of a gene. Individuals receive one version of a gene, called an allele, from each parent. If the alleles are different, the dominant allele usually will be expressed, while the effect of the other allele, called recessive, is masked. In codominance, however, neither allele is recessive and the phenotypes of both alleles are expressed.

1) Skin patterns; especially: patterns of the specialized skin of the inferior surfaces of the hands and feet.
2) The science of the study of skin patterns.

1) Small chromosomal proteins (approx 12-20 kD) possessing an open, unfolded structure and attached to the DNA in cell nuclei by ionic linkages. Classification into the various types (designated histone I, histone II, etc.) is based on the relative amounts of arginine and lysine in each.
2) A histone is a protein that provides structural support to a chromosome. In order for very long DNA molecules to fit into the cell nucleus, they wrap around complexes of histone proteins, giving the chromosome a more compact shape. Some variants of histones are associated with the regulation of gene expression.
