Glossary

Event free survival – This term is used when there has been no change in either the clinical condition of a patient’s disease or in any tests used to follow the disease such as a radiograph or blood test.

Epithelial growth factor receptor – a cell surface receptor that when activated can lead to cell growth. Mutations of this receptor have been associated with uncontrolled cell division and cancer.

Encephalogaleosynangiosis – refers to a revascularization technique used to treat Moyamoya Disease or cerebral ischemia. Technique is to expose the cortical surface fo the brain after dissecting a portion of galea free from its overlying scalp. The freed galea is then laid down over the cortical surface to remain in contact with it after closure fo the surgical incision. Over time vascular branching from the galea into the ischemic cortical surface results in revascularization.

Enzyme-linked immunoelectrotransfer blot assay.  This is an immunodianostic test assaying whether or not the antibodies are present in the tested fluid.  A positive test suggests that a person is infected or infested by the organism being tested for (i.e., the indivdual’s immune system has developed antibodies to combat the infecting/infesting organism,).

Enzyme-linked immunosorbent assay.  This is is a commonly used  technique to detect the  presence of a protein, peptide, or antibodies such as would be present due to an infective agent.  It uses an antibody against these proteins, peptides or antibodies that binds to them.  Bound to the assay’s antibody is an enzyme that reacts to the binding allowing identification of the binding event, thus identifying the presence of targeted  agent (such as the infective organism).

epithelial membrane antigen – an antigen for which an immunohistochemical stain has been developed and called by the same name. This antigen is a marker for maturation of the membrane along the epithelial cell line and is useful in differentiating small-cell, anaplastic carcinomas from lymphomas.

Material injected into a blood vessel to embolize or thrombose it.

ElectroMyoGraphy

Encephalomyosynangiosis: A surgical technique used to treat an area of the brain with poor blood supply such as can occur in Moyamoya Disease.  The technique consists of laying muscle with good blood supply directly onto the surface of the area of the brain with poor blood supply.

A gene that encodes endoglin.  Abnormalities in this gene are associated with Hereditary Hemorrhagic Telangiectasis (HHT).
