| first-order kinetics | A term describing the reaction rate of a chemical reaction in which the rate is proportional to the concentration (in moles) of only one of the reactants. Such a reaction might have an equation like rate = k[A], where k is the reaction rate constant and [A] is the concentration of a reactant A. (09 Oct 1997) |

| first-order reaction | A reaction the rate of which is proportional to the concentration of the single substance undergoing change; radioactive decay is a first-order process, defined by the equation -(dN/dt)=kN, where N is the number of atoms subject to decay (reaction), t is time, and k is the first-order decay (reaction) constant, i.e., the fraction of all atoms decaying per unit of time. See: decay constant, order. (05 Mar 2000) |
| first parallel pelvic plane | The upper opening of the true pelvis, bounded anteriorly by the pubic symphysis and the pubic crest on either side, laterally by the iliopectineal lines, and posteriorly by the promontory of the sacrum. Synonym: apertura pelvis superior, aditus pelvis, first parallel pelvic plane, pelvic brim, pelvic inlet, pelvic plane of inlet, plane of inlet. (05 Mar 2000) |
| first rank symptoms | Those symptom's that, when present, indicate that the diagnosis of schizophrenia is likely, provided that organic or toxic aetiology is ruled out: delusion of control, thought broadcasting, thought withdrawal, thought insertion, hearing one's thoughts spoken aloud, auditory hallucinations that comment on one's behaviour, and auditory hallucinations in which two voices carry on a conversation. Synonym: first rank symptoms, schneiderian first rank symptoms. (05 Mar 2000) |
| first-set rejection | Allograft transplantation between two organisms not previously sensitised to the graft tissue. Necrosis of the graft usually occurs within 10 days of transplantation. (05 Mar 2000) |
| first stage of labour | The part of labour when the cervix dilates fully (to 10 centimeters). The first stage of labour is also called the stage of dilatation. (12 Dec 1998) |
| first temporal convolution | A longitudinal gyrus on the lateral surface of the temporal lobe between the lateral (sylvian) fissure and the superior temporal sulcus. Synonym: gyrus temporalis superior, first temporal convolution, superior temporal convolution. (05 Mar 2000) |
| first visceral cleft | <anatomy> The cleft between the hyoid and mandibular arches of the embryo; the external auditory meatus is developed from its dorsal portion. Synonym: first visceral cleft. (05 Mar 2000) |
| amorphous insulin zinc suspension | Sterile suspension of insulin in buffered water for injection, modified by the addition of zinc chloride such that the solid phase of the suspension is amorphous; it contains 40 or 80 units per ml; the duration of action is equivalent to that of insulin injection. Synonym: amorphous insulin zinc suspension, semilente insulin. (05 Mar 2000) |
| anti-insulin | A factor, usually an antibody, which antagonises the action of insulin. (05 Mar 2000) |
| anti-insulin antibody | A serologic blood test that is used to detect antibodies to insulin. This test is performed in insulin dependent diabetics who exhibit insulin resistance. The presence of antibodies denotes a positive result. (27 Sep 1997) |
| biphasic insulin | <protein> A type of insulin that is a mixture of intermediate- and fast-acting insulin. (09 Oct 1997) |
| receptors, insulin | Cell surface proteins that bind insulin and trigger intracellular changes which influence the behaviour of cells. The best understood physiological consequence of insulin receptor activation is increased transport of glucose into most cells, which controls the rate of carbohydrate metabolism. The insulin receptor is a multifunctional protein complex that has intrinsic tyrosine kinase activity and is capable of autophosphorylation. (12 Dec 1998) |
| receptors, insulin-like-growth factor I | Specific proteins on or in cells to which insulin-like growth factor I (somatomedin c) binds and thereby modifies the function of the cells. These receptors contain transmembrane and cytosolic domains, bind igf-I preferentially, and have high-affinity sites for igf-II. The alpha-subunit has a mw of 130 kD and the beta subunit possesses tyrosine kinase activity. (12 Dec 1998) |
| receptors, insulin-like-growth-factor II | Specific proteins on or in cells to which insulin-like growth factor II and mannose-6-phosphate bind and thereby modify the function of the cells. These receptors have a mw of 250 kD and possess no tyrosine kinase activity. (12 Dec 1998) |
