| high blood cholesterol | A condition where there is an above normal level of cholesterol in the bloodstream. A level of over 200 mg/dl is known to be a risk factor for heart disease. Less than 200 is desirable, 200 to 239 is considered borderline high, over 240 is considered high. (27 Sep 1997) |

| NAD(P)+-dependent cholesterol dehydrogenase | <enzyme> Oxidises the 3 beta-oh group of cholesterol to cholestenone in the presence of NADP+ Registry number: EC 1.1.1.- Synonym: NADP+-dc-dehydrogenase, cholesterol 3-dehydrogenase (26 Jun 1999) |
| i-cholesterol isomerase | <enzyme> 7-hydroxy group is isomerised to position 3 on ring a to form cholesterol Registry number: EC 5.4.99.- (26 Jun 1999) |
| embolism, cholesterol | An embolism of lipid debris from an ulcerated atheromatous deposit, generally from a large artery to small arterial branches. It is usually small and rarely causes infarction. (12 Dec 1998) |
| ldl cholesterol | Low-density lipoprotein cholesterol (the bad cholesterol). (12 Dec 1998) |
| lecithin-cholesterol acyltransferase | <enzyme> An enzyme that reversibly transfers an acyl residue from a lecithin to cholesterol, forming a 1-acylglycerophosphocholine (a lysolecithin) and a cholesterol ester; a deficiency of this enzyme leads to an accumulation of unesterified cholesterol in plasma resulting in anaemia, proteinuria, renal failure, and corneal opacities; LCAT is also low in individuals with fish-eye disease. Synonym: lecithin acyltransferase. Acronym: LCAT (05 Mar 2000) |
| lecithin-cholesterol transferase | A plasma enzyme that catalyses the uptake of cholesterol esters by intermediate-density lipoproteins formed by high density lipoproteins. (05 Mar 2000) |
| lipoproteins, hdl cholesterol | Cholesterol which is contained in or bound to high density lipoproteins (hdl). High density lipoproteins transport cholesterol from peripheral tissues to the liver thereby acting as a scavenger to prevent excess accumulation and deposition of cholesterol in blood vessels. (12 Dec 1998) |
| lipoproteins, ldl cholesterol | Cholesterol which is contained in or bound to low density lipoproteins (ldl). Ldl transport cholesterol to peripheral tissues and regulate de novo cholesterol synthesis at these sites. Atherosclerosis is caused by the deposit of cholesterol on the walls of blood vessels, because of high concentrations of ldl cholesterol in plasma. (12 Dec 1998) |
| lipoproteins, vldl cholesterol | Cholesterol which is contained in or bound to very low density lipoproteins (vldl). High concentrations of vldl cholesterol are found in type IIb and type v hyperlipoproteinaemia. The end product of vldl cholesterol catabolism is ldl (low density lipoproteins). (12 Dec 1998) |
| radical mastectomy, total | Breast cancer treatment involving removal of the breast, the pectoral (chest) muscles, lymph nodes (the glands ) in the armpit and associated skin and subcutaneous tissue. (12 Dec 1998) |
| parenteral nutrition, home total | The at-home administering of nutrients for assimilation and utilization by a patient whose sole source of nutrients is via solutions administered intravenously, subcutaneously or by some other non-alimentary route. (12 Dec 1998) |
| parenteral nutrition, total | The delivery of nutrients for assimilation and utilization by a patient whose sole source of nutrients is via solutions administered intravenously, subcutaneously, or by some other non-alimentary route. The basic components of tpn solutions are protein hydrolysates or free amino acid mixtures, monosaccharides, and electrolytes. Components are selected for their ability to reverse catabolism, promote anabolism, and build structural proteins. (12 Dec 1998) |
| reversal of organs, total | This condition (medically called situs inversus totalis) involves complete transposition (right to left reversal) of the thoracic and abdominal organs. The heart is not in its usual position in the left chest but is on the right. Specifically related to the heart, this is referred to as dextrocardia (literally, right-hearted). And the stomach, which is normally in the left upper abdomen, is on the right. In patients with situs inversus totalis, all of the chest and abdominal organs are reversed and appear in mirror image when examined or visualised by tests such as X-ray filming. Situs inversus totalis has been estimated to occur once in about 6-8,000 births. Situs inversus occurs in a rare abnormal condition that is present at birth (congenital) called kartagener's syndrome.

| communication methods, total | Utilization of all available receptive and expressive modes for the purpose of achieving communication with the hearing impaired, such as gestures, postures, facial expression, types of voice, formal speech and non-speech systems, and simultaneous communication.
