| adenophyma | An obsolete term for any condition in which a gland or glandular organ is grossly enlarged as the result of inflammation. Origin: adeno-+ G. Phyma, tumour (05 Mar 2000) |
| adenosalpingitis | An abnormal condition of the fallopian tube in the place where it attaches to the uterus, characterised by nodules. (09 Oct 1997) |
| adenosarcoma | A malignant neoplasm arising simultaneously or consecutively in mesodermal tissue and glandular epithelium of the same part. (12 Dec 1998) |
| adenosatellite virus | <virology> A genus of viruses in the family Parvoviridae which are all defective viruses (unable to replicate by themselves) and depend on the co-infection of their host cell by other, nondefective viruses to help them replicate. (09 Oct 1997) |
| adenose | Relating to a gland. (05 Mar 2000) |
| adenosinase | <enzyme> An enzyme hydrolyzing adenosine to adenine and d-ribose. Synonym: adenosinase. (05 Mar 2000) |
| adenosine | <biochemistry> A ribonucleotide which consists of the nitrogenous base adenine linked to the sugar ribose. <drug> A cardiac drug used in terminating PSVT involving reentry pathways that include the AV node or Wolff-Parkinson-White syndrome. For atrial flutter, atrial fibrillation, atrial or ventricular tachycardias, adenosine may produce transient AV block that may help identify the rhythm. Pharmacologic action: Endogenous purine nucleoside that depresses AV node and sinus node activity. Brief duration of action (1-2 min). Dose: Rapid 6 mg IV bolus over 1-3 sec. May repeat at 12 mg IV bolus within 1-2 min Patients taking theophylline may require larger doses. Use a smaller dose with cardiac transplant patients. Potential complications: Common but transient - flushing, dyspnea, chest pain, bradycardia, and ventricular ectopy. Theophylline (and caffeine) blocks adenosine's effects. Dipyridamole potentiates adenosine's effects. Use other agents to avoid these drug interactions. (15 Mar 2000) |
| adenosine 3',5'-cyclic monophosphate | An activator of phosphorylase kinase and an effector of other enzymes, formed in muscle from ATP by adenylate cyclase and broken down to 5'-AMP by a phosphodiesterase; sometimes referred to as the "second messenger." A related compound (2',3') is also known. Synonym: cyclic adenylic acid, cyclic AMP, cyclic phosphate. Acronym: cAMP (05 Mar 2000) |
| adenosine 3',5'-cyclic phosphate phosphodiesterase | <enzyme> An enzyme that catalyses the hydrolysis of adenosine 3',5'-cyclic phosphate forming 5'-AMP. A crucial step in the regulation of cellular adenosine 3',5'-cyclic phosphate levels. Inhibited by caffeine. Synonym: cAMP phosphodiesterase. (05 Mar 2000) |
| adenosine 3'-phosphate | 3'-Adenylic acid. See: adenylic acid. (05 Mar 2000) |
| adenosine 3'-phosphate 5'-phosphosulfate | 3'-phosphoadenosine 5'-phosphosulfate;an intermediate in the formation of urinary ethereal sulfates, notable for containing a "high energy" sulfate bond; the 3'-OH of adenosine is replaced by -OPO3H2, the 5'-OH by -OP(O2H)-OSO3H. Synonym: active sulfate. Acronym: PAPS (05 Mar 2000) |
| adenosine 5'-diphosphate | A condensation product of adenosine with pyrophosphoric acid, formed from ATP by the hydrolysis of the terminal phosphate group of the latter compound. Acronym: ADP (05 Mar 2000) |
