A method of examining the heart to obtain information about the blood supply to the heart muscle. Special cameras take a series of pictures of the heart. Radioactive sestamibi is injected into the bloodstream and serves as a tracer. The tracer attaches to certain cells and makes them visible to the special camera. The tracer attaches to…

A genetic (inherited) condition that results in a immune deficiency disorder called severe combined immunodeficiency disease. Adenosine deaminase is an enzyme that plays a key role in salvaging purine molecules. ADA deficiency is of special interest in the history of genetics. The first successful instance of gene therapy in humans was carried out in 1990…

An enzyme that plays a key role in salvaging purine molecules.

A nucleoside containing adenine as its base. Adenosine acts to dilate the coronary arteries and is employed in the adenosine thallium scan of the heart.

Large or swollen lymph nodes. Lymph nodes can become enlarged as a result of inflammatory diseases, infection, or cancer. Synonymous with lymphadenopathy.

Also known more succinctly as adenomyosis (pronounced ad-den-o-mi-o- sis), this is a common benign condition of the uterus in which the endometrium (the mucous membrane lining the inside of the uterus) grows into the myometrium (the uterine musculature located just outside the endometrium) The endometrium and myometrium under normal circumstances live adjacent to one another as discrete neighbors. In adenomyosis,…

A common, benign condition of the uterus in which the endometrium (the inner uterus) grows into the adjacent myometrium (the uterine musculature located just outside the endometrium). The myometrium may respond to this intrusion with muscular overgrowth. If an island of endometrial tissue is contained within the myometrium, it forms an adenomyoma. Also known as endometriosis interna, endometriosis uterina, adenomyosis…

Plural form of adenomyoma.

A nodule that forms around tissue of the inner uterus (endometrial tissue) as a result of adenomyosis.

A base excision repair gene responsible for an hereditary colon cancer syndrome. MYH is located on the short (p) arm of chromosome 1 in region 1p34.3-p32.1. MYH encodes an enzyme that removes the base adenine from mispairs (with 8-oxoguanine) that arise during the replication of oxidized DNA. MYH is also known as MUTYH. A substantial proportion of…
