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) Staining of bands, or chromosome segments, allowing the precise identification of individual chromosomes or parts of chromosomes. Applications include the determination of chromosome rearrangements in malformation syndromes and cancer, the chemistry of chromosome segments, chromosome changes during evolution, and, in conjunction with cell hybridization studies, chromosome mapping.
2) The treatment of chromosomes to reveal characteristic patterns of horizontal bands. The banding patterns lend each chromosome a distinctive appearance so the 22 pairs of human nonsex chromosomes and the X and Y chromosomes can be identified and distinguished without ambiguity. Banding also permits the recognition of chromosome deletions (lost segments), chromosome duplications (surplus segments) and other types of structural rearrangements of chromosomes. (MedicineNet.com)
Industry:Health care
1) State of general ill health characterized by malnutrition, weakness, and emaciation; occurs during the course of a chronic disease.
2) General ill health, malnutrition, and weight loss, usually associated with chronic disease.
3) General physical wasting and malnutrition usually associated with chronic disease.
4) Loss of body weight and muscle mass, and weakness that may occur in patients with cancer, AIDS, or other chronic diseases.

1) Stones in the kidney, usually formed in the urine-collecting area of the kidney (kidney pelvis). Their sizes vary and most contains calcium oxalate.
2) A calculus in the kidney -- called also renal calculus.

1) Structure found in the nucleus of a cell, which contains the genes. Chromosomes come in pairs, and a normal human cell contains 46 chromosomes.
2) Physical structure consisting of DNA and supporting proteins called chromatin. Human cells normally contain 46 chromosomes identified as 23 pairs; 22 pairs are autosomes and one pair are the sex chromosomes.
3) A chromosome is an organized package of DNA found in the nucleus of the cell. Different organisms have different numbers of chromosomes. Humans have 23 pairs of chromosomes--22 pairs of numbered chromosomes, called autosomes, and one pair of sex chromosomes, X and Y. Each parent contributes one chromosome to each pair so that offspring get half of their chromosomes from their mother and half from their father.

1) Subjectively experienced sensations in the absence of an appropriate stimulus, but which are regarded by the individual as real. They may be of organic origin or associated with mental disorders.
2) Perceptions through any sense modality in the absence of an appropriate stimulus. (Usually indicative of abnormality but may be experienced occasionally by normal persons).
3) A hallucination is a false sensory perception in the absence of an external stimulus, as distinct from an illusion which is a misperception of an external stimulus. (from Wikipedia)
4) A perception of something (as a visual image or a sound) with no external cause usually arising from a disorder of the nervous system (as in delirium tremens or in functional psychosis without known neurological disease) or in response to drugs (as LSD).
5) The object of a hallucinatory perception.

1) Subnormal intellectual functioning which originates during the developmental period. This has multiple potential etiologies, including genetic defects and perinatal insults. Intelligence quotient (IQ) scores are commonly used to determine whether an individual is mentally retarded. IQ scores between 70 and 79 are in the borderline mentally retarded range. Scores below 67 are in the retarded range.
2) Subaverage intellectual ability that is equivalent to or less than an IQ of 70, is present from birth or infancy, and is manifested especially by abnormal development, by learning difficulties, and by problems in social adjustment

1) Substance dissolved in a solvent.
2) A dissolved substance; especially: a component of a solution present in smaller amount than the solvent.
Industry:Health care
1) Substances that are recognized by the immune system and induce an immune reaction.
2) Substances that cause the immune system to make a specific immune response.
3) Substances such as microorganisms or foreign tissues, cells, proteins, toxoids, or exotoxins having the ability to induce antibody formation.

1) Substances that increase the risk of neoplasms in humans or animals. Both genotoxic chemicals, which affect DNA directly, and nongenotoxic chemicals, which induce neoplasms by other mechanism, are included.
2) Any chemical that can increase the risk of neoplasms in humans or animals.
3) Any substance that causes cancer.
4) A carcinogen is an agent with the capacity to cause cancer in humans. Carcinogens may be natural, such as aflatoxin, which is produced by a fungus and sometimes found on stored grains, or manmade, such as asbestos or tobacco smoke. Carcinogens work by interacting with a cell's DNA and inducing genetic mutations.
