Endometriosis uterina: Also known 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, the endometrium trespasses upon the myometrium. The myometrium may respond to this intrusion with muscular overgrowth. If an island of endometrial tissue is contained and circumscribed within the myometrium, it forms a nodule called an adenomyoma (plural: adenomyomata). Adenomyosis is made up of adeno (gland) + myo (muscle) +osis (a condition of) = a condition of glandular tissue (referring to the endometrium) in the muscle (the myometrium). Adenomyosis goes by several other names including endometriosis interna, adenomyosis uteri and adenomyometritis.
Endometritis: Inflammation of the endometrium, the inner layer of the uterus.
Endonuclease: An enzyme that cleaves a nucleic acid (DNA or RNA) at specific sites in the nucleotide base sequence.
Endopeptidase: An enzyme that catalyzes the cleavage of peptide bonds within a polypeptide or protein. Peptidase refers to the fact that it acts on peptide bonds and endopeptidase refers to the fact that these are internal bonds. An exopeptide catalyzes the cleavage of the terminal or penultimate peptide bond, releasing a single amino acid or […]
- Endoplasmic reticulum
Endoplasmic reticulum: A structure within cells that is an extension of the nuclear membrane and in which proteins slated to become part of the nuclear membrane are translated, folded and transported. Abbreviated ER.
- Endorectal MRI
Endorectal MRI: An MRI (magnetic resonance imaging) done from inside the rectum. To do such as MRI, a surface coil within an inflated latex balloon can be positioned in the rectum. The MRI is read (interpreted) and specific areas of suspicion are identified. The MRI data can be mapped onto a 3-dimensional model to determine […]
