| calcium metabolism disorders | Disorders in the processing of calcium in the body: its absorption, transport, storage, and utilization. (12 Dec 1998) |
|---|---|
| phosphorus metabolism disorders | Disorders in the processing of phosphorus in the body: its absorption, transport, storage, and utilization. (12 Dec 1998) |
| iron metabolism disorders | Disorders in the processing of iron in the body: its absorption, transport, storage, and utilization. (12 Dec 1998) |
| due date | The estimated calendar date when a baby will be born, the date the baby is due to be born. It is also called the estimated date of confinement (EDC). (12 Dec 1998) |
| dystonia, focal, due to blepharospasm | The second most common focal dystonia, the involuntary, forcible closure of the eyelids. The first symptoms may be uncontrollable blinking. Only one eye may be affected initially, but eventually both eyes are usually involved. The spasms may leave the eyelids completely closed causing functional blindness even though the eyes and vision are normal. (12 Dec 1998) |
| dystonia, focal, due to torticollis | Spasmodic torticollis, or torticollis, is the most common of the focal dystonias. In torticollis, the muscles in the neck that control the position of the head are affected, causing the head to twist and turn to one side. In addition, the head may be pulled forward or backward.

| thrombotic disease due to protein c deficiency | Protein C is a protein in plasma that enters into the cascade of biochemical events leading to the formation of a clot. Deficiency of protein c results in thrombotic (clotting) disease and excess platelets with recurrent thrombophlebitis (inflammation of the vein that occurs when a clot forms). The clot can break loose and travel through the blood stream (thromboembolism) to the lungs causing a pulmonary embolism, brain causing a stroke (cerebrovascular accident), heart causing an early heart attack, skin causing what in the newborn is called neonatal purpura fulminans, the adrenal gland causing haemorrhage with abdominal pain, abnormally low blood pressure (hypotension), and salt loss. Protein c deficiency is due to possession of one gene (heterozygosity) in chromosome band 2q13-14. The possession of two such genes (homozygosity) is usually lethal. (12 Dec 1998) |
| basal metabolism | <biochemistry, biology> Heat production, or its measurement, of an organism at the lowest level of cell chemistry in an inactive, awake, fasting state. It may be determined directly by means of a calorimeter or indirectly by calculating the heat production from an analysis of the end products of oxidation within the organism or from the amount of oxygen utilised. (27 Jun 1999) |
| calcium metabolism | A set of biochemical processes which act to keep the level of calcium in the blood at a constant level, with enough around to build bones and teeth. (09 Oct 1997) |
| carbohydrate metabolism | <biochemistry> The breakdown of starches and sugars into smaller units that can be used by the body for energy. (27 Sep 1997) |
| respiratory metabolism | The exchange of respiratory gases in the lungs, oxidation of foodstuffs in the tissues, and production of carbon dioxide and water. (05 Mar 2000) |
| metabolism | <biochemistry> The sum of all the physical and chemical processes by which living organised substance is produced and maintained (anabolism) and also the transformation by which energy is made available for the uses of the organism (catabolism). Origin: Gr. Metaballein = to turn about, change, alter (18 Nov 1997) |
| water of metabolism | The water formed in the body by oxidation of the hydrogen of the food, the greatest amount being produced in the metabolism of fat (about 117 g/100 g of fat). Synonym: water of combustion. (05 Mar 2000) |
| Crassulacean acid metabolism | <plant biology> Physiological adaptation of certain succulent plants, in which carbon dioxide can be fixed (nonphotosynthetically) at night into malic and other acids. During the day the carbon dioxide is regenerated and then fixed photosynthetically into the Calvin Benson cycle. This adaptation permits the stomata to remain closed during the day, conserving water. (18 Nov 1997) |
| primary metabolism | Metabolic processes central to most cells; e.g., biosynthesis of macromolecules, energy production, turnover, etc. (05 Mar 2000) |
