|---|---|
| competitive behaviour | The direct struggle between individuals for environmental necessities or for a common goal. (12 Dec 1998) |
| competitive bidding | Pricing statements presented by more than one party for the purpose of securing a contract. (12 Dec 1998) |
| competitive binding assay | General term for an assay in which a binder competes for labelled versus unlabelled ligand; following separation of free and bound ligand, the ligand (the analyte assayed) is quantitated by relating bound and unbound ratios to known standards. See: enzyme-linked immunosorbent assay, radioreceptor assay, immunoassay, enzyme-multiplied immunoassay technique, radioimmunoassay. Synonym: displacement analysis, saturation analysis. (05 Mar 2000) |
| competitive inhibition | <chemistry> Inhibitor that occupies the active site of an enzyme or the binding site of a receptor and prevents the normal substrate or ligand from binding. at sufficiently high concentration of the normal ligand inhibition is lost: the Km is altered by the competitive inhibitor, but the Vmax remains the same. (05 Jan 1998) |
| competitive medical plans | Alternative health care delivery mechanisms, such as preferred provider organizations or other health insurance services or prepaid plans (other than health maintenance organizations), that meet medicare qualifications for a risk-sharing contract. (12 Dec 1998) |
| a1-trypsin inhibitor | A glycoprotein that is the major protease inhibitor of human serum, is synthesised in the liver, and is genetically polymorphic due to the presence of over 20 alleles; individuals appropriately homozygous are deficient in a1-trypsin and are predisposed to pulmonary emphysema and juvenile hepatic cirrhosis because of alterations in the amino acid and sialic acid components of the glycoprotein. A1-Antitrypsin also inhibits thrombin. Synonym: a1-trypsin inhibitor, human a1-proteinase inhibitor. (05 Mar 2000) |
| ACE inhibitor | <pharmacology> A group of antihypertensive medications that work by inhibiting an enzyme (angiotensin-converting enzyme) that is important in the regulation of blood pressure. Studies have also indicated that it may help prevent or slow the progression of kidney disease in patients with diabetes. Examples include: captopril, ramipril, enalapril, losartan potassium, bepridil and lisinopril. (12 Mar 1998) |
| aldose reductase inhibitor | <pharmacology> A class of drugs being studied as a way to prevent eye and nerve damage in people with diabetes. Aldose reductase is an enzyme that is normally present in the eye and in many other parts of the body. It helps change glucose (sugar) into a sugar alcohol called sorbitol. Too much sorbitol trapped in eye and nerve cells can damage these cells, leading to retinopathy and neuropathy. Drugs that prevent or slow (inhibit) the action of aldose reductase are being studied as a way to prevent or delay these complications of diabetes. (09 Oct 1997) |
| angiotensin-converting enzyme inhibitor | <pharmacology> A class of drugs used in the treatment of hypertension and heart failure. They exert their haemodynamic effect mainly by inhibiting the renin-angiotensin system and produce a reduction of peripheral arterial resistance. They also modulate sympathetic nervous system activity and increase prostaglandin synthesis. They cause mainly vasodilation and mild natriuresis without affecting heart rate and contractility. (14 Aug 2000) |
| aromatase inhibitor | Drugs, such as aminoglutethimide, that inhibit aromatase, an enzyme used in the synthesis of oestrogens. (05 Mar 2000) |
| beta-lactamase inhibitor | <pharmacology> Drugs such as clavulanic acid, which are used to inhibit bacterial beta-lactamases; often used with a penicillin or cephalosporin to overcome drug resistance. (05 Mar 2000) |
| Bowman-Birk inhibitor | A polypeptide that will inhibit both trypsin and chymotrypsin. (05 Mar 2000) |
| C1 esterase inhibitor | An a2-neuraminoglycoprotein that inhibits the enzymatic activity of C1 esterase, the activated first component of complement. A deficiency of this inhibitor results in a lack of inhibition of C1r and C1s leading to uncontrolled activation of the complement cascade and oedema. (05 Mar 2000) |
| carbonate dehydratase inhibitor | An agent, usually chemically related to the sulfonamides, that inhibits the activity of carbonate dehydratase, producing a general decrease in the formation of H2CO3 in the tissues. See: acetazolamide, dichlorphenamide. Synonym: carbonic anhydrase inhibitor. (05 Mar 2000) |
| competitive inhibitor |
A molecule whose inhibitory effects on an enzyme can be overcome by increased substrate concentration.
