| 3-oxoacyl-(acyl-carrier-protein) synthase | <enzyme> An enzyme of long-chain fatty acid synthesis, that adds a two-carbon unit from malonyl-(acyl carrier protein) to another molecule of fatty acyl-(acyl carrier protein), giving a beta-ketoacyl-(acyl carrier protein) with the release of carbon dioxide. Chemical name: Acyl-(acyl carrier protein):malonyl-(acyl-carrier-protein) C-acyltransferase (decarboxylating) Registry number: EC 2.3.1.41 (12 Dec 1998) |
|---|---|
| latent carrier | A person, typically a prospective parent, bearing the appropriate genotype of a trait (homozygous for recessive, homozygous or heterozygous for dominant, hemizygous or homozygous for X-linked) that manifests the trait only under certain conditions, e.g., age, an environmental insult, etc. (05 Mar 2000) |
| long-chain-fatty-acid-(acyl-carrier-protein) ligase | <enzyme> Fatty acid, acyl-carrier-protein-sh and ATP gives acyl-(acyl-carrier-protein), AMP and ppi Registry number: EC 6.2.1.20 Synonym: fatty acid-acyl carrier protein ligase (AMP), acyl-(acyl-carrier-protein)synthetase, aacp synthetase, fatty acyl-acyl carrier protein synthase, vibrio harveyi, acyl-(acyl-carrier-protein) synthetase, acyl-acp synthetase (26 Jun 1999) |
| artificial passive immunity | See: acquired immunity. (05 Mar 2000) |
| passive | Neither spontaneous nor active, not produced by active efforts. Origin: L. Passivus (18 Nov 1997) |
| passive agglutination | Agglutination of particles that have been coated with soluble antigen, by antiserum specific for the adsorbed antigen. Synonym: indirect agglutination. (05 Mar 2000) |
| passive-aggressive behaviour | Apparently compliant behaviour, with intrinsic obstructive or stubborn qualities, to cover deeply felt aggressive feelings that cannot be more directly expressed. (05 Mar 2000) |
| passive-aggressive personality | A personality disorder in which aggressive feelings are manifested in passive ways, especially through mild obstructionism and stubbornness. (05 Mar 2000) |
| passive-aggressive personality disorder | A personality disorder characterised by an indirect resistance to demands for adequate social and occupational performance; anger and opposition to authority and the expectations of others that is expressed covertly by obstructionism, procrastination, stubbornness, dawdling, forgetfulness, and intentional inefficiency. (12 Dec 1998) |
| passive anaphylaxis | A reaction resulting from inoculation of antigen in an animal previously inoculated intravenously with specific antiserum from another animal, a latent period being required between the two inoculations. Synonym: antiserum anaphylaxis. (05 Mar 2000) |
| passive atelectasis | The pulmonary collapse that occurs due to a space-occupying intrathoracic process such as pneumothorax or hydrothorax. (05 Mar 2000) |
| passive clot | A clot formed in an aneurysmal sac consequent to the cessation or slowing of circulation through the aneurysm. (05 Mar 2000) |
| passive congestion | Congestion caused by obstruction or slowing of the venous drainage, resulting in partial stagnation of blood in the capillaries and venules. (05 Mar 2000) |
| passive cutaneous anaphylaxis | An evanescent cutaneous reaction occurring when antibody is injected into a local area on the skin and antigen is subsequently injected intravenously along with a dye. The dye makes the rapidly occurring capillary dilatation and increased vascular permeability readily visible by leakage into the reaction site. Pca is a sensitive reaction for detecting very small quantities of antibodies and is also a method for studying the mechanisms of immediate hypersensitivity. (12 Dec 1998) |
| passive cutaneous anaphylaxis test | An animal is injected intradermally with antibody (usually IgE) and subsequently challenged intravenously with a mixture of antigen and Evans blue dye 24-48 hours later. A dark blue area indicates a positive reaction due to the leakage of the dye at the site of antigen-antibody reactions. (05 Mar 2000) |
