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) Treatment with anticancer drugs.
2) The use of chemical agents in the treatment or control of disease or mental disorder.

1) Tumor marker is a substance present in or produced by a tumor or by the host, that can be used for differentiating neoplastic from normal tissue based on measurements in body fluids, secretions, cells, and/or tissues. Markers are used in diagnosis, staging and prognosis of cancer, provide an estimation of tumor burden, and serve for monitoring effects of therapy, detecting recurrence, localization of tumors, and screening in general populations. Tumor markers have been categorized as follows: enzymes, isoenzymes, hormones, oncofetal antigens, carbohydrate epitopes, oncogene products, and genetic changes. There is no identified tumor marker that fits the ideal specificity profile.
2) A substance sometimes found in the blood, other body fluids, or tissues. A high level of tumor marker may mean that a certain type of cancer is in the body. Examples of tumor markers include CA 125 (ovarian cancer), CA 15-3 (breast cancer), CEA (ovarian, lung, breast, pancreas, and gastrointestinal tract cancers), and PSA (prostate cancer). Also called biomarker.
3) Substances found in abnormal amounts in the blood, in other body fluids, or in tumor tissue of some patients with certain types of cancer.

1) Twelve pairs of nerves that carry general afferent, visceral afferent, special afferent, somatic efferent, and autonomic efferent fibers.
2) Any of the 12 paired nerves that originate in the brain stem.
3) Any of the 12 paired nerves that arise from the lower surface of the brain with one of each pair on each side and pass through openings in the skull to the periphery of the body.

1) Two small paired endocrine glands in the region of the thyroid gland. They secrete parathyroid hormone and are concerned with the metabolism of calcium and phosphorus.
2) One of four pea-sized glands found on the thyroid. The parathyroid hormone produced by these glands increases the calcium level in the blood.

1) Unequal curvature of the refractive surfaces of the eye. Thus a point source of light cannot be brought to a point focus on the retina but is spread over a more or less diffuse area. This results from the radius of curvature in one plane being longer or shorter than the radius at right angles to it. (Dorland, 27th ed)
2) optical defect in which refractive power is not uniform in all directions (meridians); light rays entering the eye are bent unequally by different meridians, which prevents formation of a sharp image focus on the retina.

1) Unit of length for DNA fragments equal to 1000 nucleotides.
2) A unit of measure of the length of a nucleic-acid chain (as of DNA or RNA) that equals one thousand base pairs.

1) Unpleasant, but not necessarily irrational or pathological, mood state characterized by sadness, despair, or discouragement; "the blues"; may also involve low self-esteem, social withdrawal, and somatic symptoms such as eating and sleep disturbance.
2) A mental state of depressed mood characterised by feelings of sadness, despair and discouragement.
