| closed system | <biology, ecology> A chemical or biological system that exchanges no matter or energy with the ouside environment. (12 Mar 1998) |
|---|---|
| covalently closed circular DNA | <molecular biology> A circular molecule of double-stranded DNA which is supercoiled, or coiled up on itself due to internal tensions, because there are no breaks in the phosphate backbone (upon which the nucleotide bases are mounted) to relieve the tensions and allow it to form an open circle. (09 Oct 1997) |
| head injuries, closed | Organic or functional damage resulting from trauma to the head where continuity of the scalp and mucous membranes is maintained. When brain injury results from closed head injuries, the primary cause is mechanical stretching and shearing of nerve fibres. Also common are focal intracranial lesions including haematomas and contusions. (12 Dec 1998) |
| semi-closed anaesthesia | Inhalation anaesthesia using a circuit in which a portion of the exhaled air is exhausted from the circuit and a portion is rebreathed following absorption of carbon dioxide. (05 Mar 2000) |
| semi-closed circle | A circuit for administration of an inhalation anaesthetic in which partial rebreathing with carbon dioxide absorption is combined with loss from the circuit of a portion of respired gases through valves. (05 Mar 2000) |
| ecological systems, closed | Systems that provide for the maintenance of life in an isolated living chamber through reutilization of the material available, in particular, by means of a cycle wherein exhaled carbon dioxide, urine, and other waste matter are converted chemically or by photosynthesis into oxygen, water, and food. (12 Dec 1998) |
| fractures, closed | Fractures in which the break in bone is not accompanied by an external wound. (12 Dec 1998) |
| afferent loop syndrome | <syndrome> A complication of gastrojejunostomy, caused by acute or chronic obstruction of the afferent loop due to hernia, intussusception, kinking, volvulus, etc. It is characterised by pain and vomiting of bile-stained fluid and includes acute afferent loop obstruction and bilious vomiting. (12 Dec 1998) |
| arch-loop-whorl system | See: Galton's system of classification of fingerprints. (05 Mar 2000) |
| Biebl loop | A continuous loop of small intestine brought through the abdominal wall to a subcutaneous location, for observation of motility. (05 Mar 2000) |
| blind loop syndrome | <syndrome> Malabsorption, especially of vitamin b12 or folic acid, due to metabolic competition by bacteria proliferating in a segment of small intestine excluded from normal peristaltic movement; it may occur as a postoperative complication of side-to-side anastomosis of intestine, as a result of intestinal diverticula, fistula, etc. (12 Dec 1998) |
| bulboventricular loop | The portion of the early-somite embryonic cardiac tube that evolves into the ventricle and bulbus cordis. Synonym: ventricular loop. (05 Mar 2000) |
| gamma loop | The reflex arc consisting of small anterior horn cells and neuroma, their small fibres projecting to the intrafusal bundle producing its contraction, which initiates the afferent impulses that pass through the posterior root to the anterior horn cells, inducing a stretch reflex. Synonym: gamma motor neurons, gamma motor system, Granit's loop. (05 Mar 2000) |
| vector loop | <physiology> An irregular, usually elliptical, curve representing the average direction and magnitude of the heart's action from moment to moment throughout the cardiac cycle. See: vector, vectorcardiogram. (06 Mar 2000) |
| ventricular loop | The portion of the early-somite embryonic cardiac tube that evolves into the ventricle and bulbus cordis. Synonym: ventricular loop. (05 Mar 2000) |
