| advanced concepts torus i | <physics> A steady-state toroidal device built primarily for studies of RF heating and RF current drive. Acronym: ACT I (09 Oct 1997) |
| advanced fuels | <radiobiology> There are several elements or isotopes that could be fused together, besides the DT fuel mixture. Many such fuel combinations would have various advantages over DT, but it is generally more difficult to achieve fusion with these advanced fuels than with the DT mix. (09 Oct 1997) |
| advanced life support | Definitive emergency medical care that includes defibrillation, airway management, and use of drugs and medications. Compare: basic life support. (05 Mar 2000) |

| advanced toroidal facility | <physics> A large stellarator device developed at Oak Ridge National Lab (ORNL), but now retired. Acronym: ATF (09 Oct 1997) |
| glycosylation end products, advanced | Products derived from the nonenzymatic reaction of glucose and proteins in vivo that exhibit a yellow-brown pigmentation and an ability to participate in protein-protein cross-linking. These substances are involved in biological processes relating to protein turnover and it is believed that their excessive accumulation contributes to the chronic complications of diabetes mellitus.

| integrated advanced information management systems | A concept, developed in 1983 under the aegis of and supported by the national library of medicine under the name of integrated academic information management systems, to provide professionals in academic health sciences centres and health sciences institutions with convenient access to an integrated and comprehensive network of knowledge. It addresses a wide cross-section of users from administrators and faculty to students and clinicians and has applications to planning, clinical and managerial decision-making, teaching, and research. It provides access to various types of clinical, management, educational, etc., databases, as well as to research and bibliographic databases. In august 1992 the name was changed from integrated academic information management systems to integrated advanced information management systems to reflect use beyond the academic milieu.

| rate, maternal mortality | The number of maternal deaths related to childbearing divided by the number of live births (or by the number of live births + foetal deaths) in that year. The maternal mortality rate in the united states in 1993 (and 1994) was 0.1 per 1,000 live births, or 1 mother dying per 10,000 live births. (12 Dec 1998) |

| maternal cotyledon | A unit of the placenta made up of trophoblastic cells, fibrous tissue, and abundant blood vessels, which is visible grossly on the maternal surface as an irregularly shaped lobe circumscribed by a deep cleft and made up of a stem villus with numerous branching free villi and anchoring villi; placental vessels in the chorionic plate supply the stem villus and its branches, allowing gas and metabolite exchange across the trophoblastic layer with maternal blood in the intervillous space; traditionally called clinicians' cotyledon.
