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.
The nickname of the International HapMap Project, an international project that seeks to relate variations in human DNA sequences with genes associated with health. 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. The HapMap describes common patterns of genetic variation among people.
Industry:Medical
The two chromosomes from a particular pair, normally one inherited from the mother and one from the father, containing the same genetic loci in the same order.
Industry:Medical
1) Excessive accumulation of cerebrospinal fluid within the cranium which may be a congenital or acquired disorder; hydrocephalus ex-vacuo refers to ventricular dilation that occurs as a result of brain substance loss from cerebral infarction and other conditions.
2) An abnormal increase in the amount of cerebrospinal fluid within the cranial cavity that is accompanied by expansion of the cerebral ventricles, enlargement of the skull and especially the forehead, and atrophy of the brain.
3) The abnormal buildup of cerebrospinal fluid in the ventricles of the brain.
Industry:Medical
Therapeutic use of hormones to alleviate the effects of hormone deficiency.
Industry:Medical
1) Half the diploid or normal number of chromosomes in a somatic cell; the number of chromosomes in a gamete (egg or sperm) cell, which in humans is 23 chromosomes, one chromosome from each chromosome pair
2) A single set of chromosomes (half the full set of genetic material) present in the egg and sperm cells of animals and in the egg and pollen cells of plants. Human beings have 23 chromosomes in their reproductive cells.
3) Haploid is the quality of a cell or organism having a single set of chromosomes. Organisms that reproduce asexually are haploid. Sexually reproducing organisms are diploid (having two sets of chromosomes, one from each parent). In humans, only their egg and sperm cells are haploid.
Industry:Medical
Analysis of the number and structure of the chromosomes when cell division has been arrested and the chromosomes stained at an early stage (pro-metaphase) of mitosis. The chromosomes of a high resolution study appear longer and reveal 700-1200 bands, allowing more detailed analysis of the chromosome structure, as opposed to the typical 300-600 bands observed with routine metaphase banding.
Industry:Medical
A condition in which the heart is unable to pump blood at an adequate rate or in adequate volume.
Industry:Medical
1) The total gene complement, about 3 billion base pairs of DNA, contained in the human chromosomes.
2) The full collection of genes needed to produce a human being.
