| fat substitutes | Compounds used in food or in food preparation to replace dietary fats. They may be carbohydrate-, protein-, or fat-based. Fat substitutes are usually lower in calories but provide the same texture as fats. (12 Dec 1998) |
| fat tide | An increase in the fat content of blood and lymph following a meal. (05 Mar 2000) |
| unilocular fat | Adipose tissue in which the fat is present in a single droplet within the fat cells. Synonym: white fat. (05 Mar 2000) |
| unsaturated fat | <biochemistry> A fat that contains a carbon-carbon double bond, or a fat containing unsaturated fatty acids, such a fatty acid has double or triple covalent bonds and is thus able to add more atoms. Unsaturated fats are believed to lower blood cholesterol levels and are found at high levels in vegetable oils (olive oil, safflower oil, etc.) As a general rule, unsaturated fats are liquid at room temperature. (09 Oct 1997) |
| low-fat diet | A diet containing minimal amounts of fat.Diets containing low amounts of fat and cholesterol are designed to reduce the risk of heart disease and, in some cases, cancer. Dozens of such diets have been promulgated, both by medical and lay advisors. Their popularity can be attributed in part to clinical studies that have, since the 1980s, revealed, on the one hand, the hazards of eating high-fat, high-cholesterol foods and, on the other, the benefits of ingesting less saturated fat and LDL (low density lipoprotein) cholesterol. Although coronary deaths have been reduced by roughly 30% since 1970, the aim of health officials is to further reduce heart attack rates. The average cholesterol level among adult Americans has fallen from 213 to 205 mg/dl since 1978. However, the National Cholesterol Education Program recommends that individuals maintain a total cholesterol level of no more than 200 mg/dl, with LDL at less than 130 mg/dl and HDL (high density lipoprotein) around 60 mg/dl. About one-half of American adults exceed those recommendations. Low-fat, low-cholesterol diets are rich in whole grains, fresh fruits and vegetables, and legumes, and limit or exclude consumption of processed oils, dairy products, nuts and seeds, and meats. See atherosclerosis, free radicals. (05 Mar 2000) |
| acetone body | <biochemistry> Any of the three compounds created by acetyl coenzyme A (acetoacetate, hydroxybutyrate, and acetone) which are water-soluble cellular fuels normally exported by the liver. They can build up in the blood and body tissues because of starvation, untreated diabetes mellitus, or other disorders that interfere with carbohydrate metabolism. The body rids itself of ketones mainly through urine, but it rids itself of acetone through the lungs, which gives the breath a characteristic fruity odour. If ketones build up in the body long enough, they cause serious illness and coma (see ketoacidosis.) (09 Oct 1997) |
| acute inclusion body encephalitis | The most common acute encephalitis, caused by HSV-1; affects persons of any age; preferentially involves the inferomedial portions of the temporal lobe and the orbital portions of the frontal lobes; pathologically, severe haemorrhagic necrosis is present along with, in the acute stages, intranuclear eosinophilic inclusion bodies in the neurons and glial cells. Synonym: acute inclusion body encephalitis, herpes encephalitis. (05 Mar 2000) |
| adrenal body | See adrenal gland. (12 Dec 1998) |
| alveolar body | That portion of bone in either the maxilla or the mandible which surrounds and supports the teeth. (12 Dec 1998) |
| amygdaloid body | Almond-shaped group of basal nuclei anterior to the inferior horn of the lateral ventricle of the brain, within the temporal lobe. The amygdala is part of the limbic system. (12 Dec 1998) |
| amylogenic body | A plant plastid involved in the synthesis and storage of starch. Found in many cell types, but particularly storage tissues. Characteristically has starch grains in the plastid stroma. (18 Nov 1997) |
| anococcygeal body | <anatomy> A musculofibrous band that passes between the anus and the coccyx. Synonym: ligamentum anococcygeum, anococcygeal body, raphe anococcygea, Symington's anococcygeal body. (05 Mar 2000) |
| anterior quadrigeminal body | The paired, larger, rounded anterior eminence of the laminae of mesencephalic tectum; major afferent connections of the superficial layers are the retina and striate cortex; input to deep layers of the colliculus are polymodal. Its efferent connections are with the lower brainstem and spinal cord (tectobulbar tract and tectospinal tract) and with the pulvinar and other cell groups in the caudal part of the thalamus; participates in extrageniculate visual pathway. Synonym: colliculus superior, anterior quadrigeminal body, corpus quadrigeminum anterius. (05 Mar 2000) |
| aortic body tumour | Aortic body, carotid body, chemoreceptor, or glomus jugulare tumour; nonchromaffin paraganglioma; receptoma; a relatively rare, usually benign neoplasm originating in the chemoreceptor tissue of the carotid body, glomus jugulare, and aortic bodies; consisting histologically of rounded or ovoid hyperchromatic cells that tend to be grouped in an alveolus-like pattern within a scant to moderate amount of fibrous stroma and a few large thin-walled vascular channels. Compare: paraganglioma. Synonym: aortic body tumour, carotid body tumour, chemoreceptor tumour, glomus jugulare tumour, nonchromaffin paraganglioma. Origin: chemo-+ G. Dektes, receiver, fr. Dechomai, to receive, + -oma, tumour (05 Mar 2000) |
