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) Abnormal involuntary movements which primarily affect the extremities, trunk, or jaw that occur as a manifestation of an underlying disease process. Conditions which feature recurrent or persistent episodes of dyskinesia as a primary manifestation of disease may be referred to as dyskinesia syndromes (see MOVEMENT DISORDERS). Dyskinesias are also a relatively common manifestation of BASAL GANGLIA DISEASES.
2) Difficulty moving; distortion or impairment of voluntary movement, as in tic, spasm, or myoclonus.
3) Abnormal involuntary motor processes that occur due to underlying disease processes.
Industry:Medical
1) The outer of the three germ layers of the embryo.
2) Outermost of the three germ layers of the embryo (the other two being mesoderm and endoderm); ectoderm gives rise to epidermis and neural tissue.
Industry:Medical
1) The presence of an extra segment of DNA, resulting in redundant copies of a portion of a gene, an entire gene, or a series of genes, usually caused by unequal crossing-over during gene replication when gametes are formed in meiosis
2) Duplication is a type of mutation that involves the production of one or more copies of a gene or region of a chromosome. Gene and chromosome duplications occur in all organisms, though they are especially prominent among plants. Gene duplication is an important mechanism by which evolution occurs.
Industry:Medical
1) Of, relating to, or affecting the intestines (enteric diseases); broadly: alimentary.
2) Being or possessing a coating designed to pass through the stomach unaltered and to disintegrate in the intestines (enteric aspirin).
Industry:Medical
1) Ductless glands that secrete substances which are released directly into the circulation and which influence metabolism and other body functions.
2) A gland (as the thyroid or the pituitary) that produces an endocrine secretion -- called also ductless gland, gland of internal secretion.
Industry:Medical
An individual who has two different gene mutations (i.e., is heterozygous) at two separate genetic loci.
Industry:Medical
1) Granular leukocytes with a nucleus that usually has two lobes connected by a slender thread of chromatin, and cytoplasm containing coarse, round granules that are uniform in size and stainable by eosin.
2) A white blood cell or other granulocyte with cytoplasmic inclusions readily stained by eosin.
Industry:Medical
A test result which indicates that an individual is affected and/or has a certain gene mutation when he or she is actually unaffected and/or does not have the mutation; i.e., a positive test result in a truly unaffected individual.
Industry:Medical
1) A method of separating large molecules (such as DNA fragments or proteins) from a mixture of similar molecules. An electric current is passed through a medium containing the mixture, and each kind of molecule travels through the medium at a different rate, depending on its electrical charge and size. Agarose and acrylamide gels are the media commonly used for electrophoresis of proteins and nucleic acids.
2) Electrophoresis is a laboratory technique used to separate DNA, RNA, or protein molecules based on their size and electrical charge. An electric current is used to move molecules to be separated through a gel. Pores in the gel work like a sieve, allowing smaller molecules to move faster than larger molecules. The conditions used during electrophoresis can be adjusted to separate molecules in a desired size range.
Industry:Medical
1) The muscles that move the eye. Included in this group are the medial rectus, lateral rectus, superior rectus, inferior rectus, inferior oblique, superior oblique, musculus orbitalis, and levator palpebrae superioris.
2) Voluntary muscles which control eye movement.
