The sum total of changes in an organism in order to achieve a balance (homeostasis). Catabolic burns up, anabolic stores and builds up; the sum of their work is metabolism.... metabolism
Change of a mature type of cell in a tissue to another mature type of cell usually present in another tissue; e.g., development of squamous epithelium in the trachea among the normal respiratory epithelium = squamous metaplasia.... metaplasia
The spread of cancer cells through the blood, lymphatics or directly and establishment of these newgroups of cells at locations distant from the original cancer.... metastasis
The basic rate of combustion by a person, usually measured after sleep and while resting.... basal metabolism
A statistical procedure to combine results from different studies on a similar topic. The combination of results from multiple studies may produce a stronger conclusion than can be provided by any singular study. Meta-analysis is generally most appropriate when there are no definitive studies on a topic and non-definitive studies are in some disagreement.... meta-analysis
Pain affecting the metatarsal region of the foot. It is common in adolescents, and associated with FLAT-FOOT; in adults it may be a manifestation of RHEUMATOID ARTHRITIS. Morton’s metatarsalgia is a form associated usually with the nerve to the second toe cleft, often induced by the compression of tight shoes.... metatarsalgia
A by-product, waste product, or endotoxin produced as the result of metabolism, both normal and defensive.... metabolites
An immature granulocyte (white blood cell) usually found in the bone marrow’s blood-making tissue. It can, however, appear in the blood in a range of diseases, including infection.... metamyelocyte
The extremity of a long bone where it joins the epiphysis (see BONE – Growth of bones).... metaphysis
Metatarsus is the group name of the ?ve metatarsal bones in the foot. Metatarsus varus is the condition characterised by deviation of the forefoot towards the other foot. It is a common condition in newborn babes and almost always corrects itself spontaneously. Only in the rare cases in which it is due to some deformity of the bones or muscles of the foot is any treatment required.... metatarsus
Any substance involved in a metabolic reaction (a biochemical reaction in the body). The term metabolite is sometimes used to refer only to the products of a metabolic reaction. (See also metabolism.)... metabolite
A process by which the body destroys and excretes drugs, so limiting their duration of action. Phase 1 metabolism consists of transformation by oxidation, reduction, or hydrolysis. In phase 2 this transformed product is conjugated (joined up) with another molecule to produce a water-soluble product which is easier to excrete.... drug metabolism
The ?ve long bones which occupy the HAND between the carpal bones at the wrist and the phalanges of the ?ngers. The large rounded ‘knuckles’ at the root of the ?ngers are formed by the heads of these bones.... metacarpal bones
See METASTASIS.... metastatic
The ?ve bones in the foot which correspond to the METACARPAL BONES in the hand, lying between the tarsal bones, at the ankle, and the toes.... metatarsal bones
That division of the animal kingdom which embraces all animals whose cells become differentiated to form tissues. It includes all animals except the protozoa.... metazoa
One of 5 long, cylindrical bones within the hand. The bones run from the wrist to the base of each digit, with the heads of the bones forming the knuckles.... metacarpal bone
One of 5 long, cylindrical bones within the foot. The bones make up the central skeleton of the foot and are held in an arch by the surrounding ligaments.... metatarsal bone
The joint between each metatarsal bone and its adjoining toe bone (see phalanges). The metatarsophalangeal joint at the base of the big toe is commonly affected by gout and by hallux rigidus.... metatarsophalangeal joint
a process in which a drug administered by mouth is absorbed from the gastrointestinal tract and transported via the portal vein to the liver, where it is metabolized. As a result, in some cases only a small proportion of the active drug reaches the systemic circulation and its intended target tissue. First-pass metabolism can be bypassed by giving the drug via sublingual or buccal routes.... first-pass metabolism
any one of a group of inherited conditions in which there is a disturbance in either the structure, synthesis, function, or transport of protein molecules. There are over 1500 inborn errors of metabolism; examples are *phenylketonuria, *homocystinuria, and *hypogammaglobulinaemia.... inborn error of metabolism
(MMP) any one of a group of zinc-containing proteases capable of digesting the extracellular tissue matrix. These enzymes play an important role in cell division, cell migration, inflammation, neoplastic invasion (*metastasis), and *angiogenesis.... matrix metalloproteinase
(insulin resistance syndrome, syndrome X) a very common condition in which impaired glucose tolerance, impaired fasting glucose, or type 2 diabetes (see glucose tolerance test) is combined with central obesity (increased fat within the abdomen), raised blood pressure (*hypertension), and *hyperlipidaemia. It is associated with a risk of premature vascular disease (heart attack and stroke). The principal underlying cause is *insulin resistance, which is genetically determined.... metabolic syndrome
1. adj. relating to the bones of the hand (*metacarpus). 2. n. any of the bones forming the metacarpus.... metacarpal
n. the five bones of the hand that connect the *carpus (wrist) to the *phalanges (digits).... metacarpus
n. a chromosome in which the centromere is at or near the centre of the chromosome. —metacentric adj.... metacentric
n. (pl. metacercariae) a mature form of the *cercaria larva of a fluke. Liver fluke metacercariae are enveloped by thin cysts and develop on various kinds of vegetation.... metacercaria
(metachromatism) n. 1. the property of a dye of staining certain tissues or cells a colour that is different from that of the stain itself. 2. the variation in colour produced in certain tissue elements that are stained with the same dye. 3. abnormal coloration of a tissue produced by a particular stain. —metachromatic adj.... metachromasia
n. philosophical study of the theoretical foundations of *ethics, as opposed to practical ethics.... metaethics
n. a genus of small flukes, usually less than 3 mm in length, that are common as parasites of dogs and cats in the Far East, N Siberia, and the Balkan States. Adult flukes of M. yokogawai occasionally infect the human duodenum if undercooked fish (the intermediate host) is eaten. They may cause inflammation and some ulceration of the intestinal lining, which produces a mild diarrhoea. Flukes can be easily removed with tetrachloroethylene.... metagonimus
n. a condition in which objects appear distorted. It is usually due to a disorder of the retina affecting the *macula (the most sensitive part).... metamorphopsia
metabolites of the hormones adrenaline and noradrenaline, respectively. Both hormones are released in excess from a *phaeochromocytoma, and measurement of their metabolites is the most reliable screening test for this rare but potentially lethal condition. The test is best carried out on a complete 24-hour urine collection.... metanephrine and normetanephrine
n. the excretory organ of the fetus, which develops into the kidney and is formed from the rear portion of the *nephrogenic cord. It does not become functional until birth, since urea is transferred across the placenta to the mother.... metanephros
