| complex liver mass in kids | <radiology> Epithelial, FNH (uncommon, F greater than M), hepatic adenoma (uncommon, F greater than M), hepatoma (increased aFP in 90%), hepatoblastoma (increased aFP, less than 2 years of age), mesenchymal, hamartoma, cavernous haemangioma, haemangioendothelioma, embryonal rhabdomyosarcoma (obstructs common bile duct; less than 5 years of age), undifferentiated sarcoma, teratoma, abscess / haematoma / complicated cyst (12 Dec 1998) |
|---|---|
| complex locus | A set of closely linked genetic loci with a common function, as in the major histocompatibility complex locus. (05 Mar 2000) |
| complex medium | <cell culture> A medium whose precise chemical composition is unknown. Compare: defined medium. (05 Jan 1998) |
| complex odontoma | <tumour> An odontoma in which the various odontogenic tissues are organised in a haphazard arrangement with no resemblance to teeth. (05 Mar 2000) |
| complex partial seizure | <neurology> Seizures with elaborate and multiple sensory, motor, and/or psychic components. A common feature is the clouding of consciousness and amnesia for the event. Some clinical manifestations may include more complex behaviours like burst of anger, emotional outbursts, fear or automatisms. The EEG often reveals spike discharges in the temporal lobe during sleep. (05 Jan 1998) |
| complex precipitated epilepsy | A form of reflex epilepsy initiated by specialised sensory stimuli, e.g., certain visual patterns. (05 Mar 2000) |
| platelet glycoprotein gpib-ix complex | Platelet membrane glycoprotein complex essential for normal platelet adhesion and clot formation at sites of vascular injury. It is composed of three polypeptides, gpib alpha, gpib beta, and gpix. Glycoprotein ib functions as a receptor for von willebrand factor and for thrombin. Congenital deficiency of the gpib-ix complex results in bernard-soulier syndrome. The platelet glycoprotein gpv associates with gpib-ix and is also absent in bernard-soulier syndrome. (12 Dec 1998) |
| platelet glycoprotein gpiib-iiia complex | Platelet membrane glycoprotein complex important for platelet adhesion and aggregation. The complex is an integrin which recognises the arginine-glycine-aspartic acid (rgd) sequence present on several adhesive proteins. As such, it is a receptor for fibrinogen, von willebrand factor, fibronectin, vitronectin, and thrombospondin. A deficiency of gpiib-iiia results in glanzmann's thrombasthenia. (12 Dec 1998) |
| multienzyme complex | Cluster of distinct enzymes catalysing consecutive reactions of a metabolic pathway, that remain physically associated through purification procedures. Multifunctional enzymes, found in eukaryotes, are a somewhat different phenomenon, since the several enzymic activities are associated with different domains of a single polypeptide. (18 Nov 1997) |
| mycobacterium avium complex | A serious opportunistic infection caused by two similar bacteria (Mycobacterium avium and Mycobacterium intercellulare) found in the soil and dust particles. In AIDS, MAC can spread through the bloodstream to infect lymph nodes, bone marrow, liver, spleen, spinal fluid, lungs and intestinal tract. Typical symptoms of MAC include night sweats, weight loss, fever, fatigue, diarrhoea and enlarged spleen. MAC is usually found in people with CD4 counts below 100. MAC is also called MAI. (09 Oct 1997) |
| mycobacterium avium complex disease | <infectious disease> A disease process caused by infection by the organism Mycobacterium avium intracellulare. Almost unheard of in a patient with a normal functioning immune system, this can be a common infection in those with advanced HIV infection. (27 Sep 1997) |
| Mycobacterium avium-intracellulare complex | An opportunistic agent of people with AIDS. Difficult to treat because Mycobacterium is resistant to many antibiotics. May also cause chronic lower respiratory tract infections. (05 Mar 2000) |
| myoelectric complex, migrating | Bursts of depolarisation that move from the stomach to the ileocaecal valve at regular frequency during the interdigestive period. The complex and its accompanying motor activity periodically cleanse the bowel of interdigestive secretion and debris in preparation for the next meal. (12 Dec 1998) |
| polyvinylpyrrolidone-iodine complex | <chemical> A water soluble complex of iodine with polyvinylpyrrolidone. Applied as an antiseptic in the form of solutions or ointments, it releases iodine. Used in cleansing and disinfecting the skin, preparing the skin preoperatively, and treating infections susceptible to iodine. 1-ethenyl-2-pyrrolidone homopolymer complexed with iodine. An iodinated polyvinyl polymer used as topical antiseptic in surgery and for skin and mucous membrane infections, also as aerosol. The iodine may be radiolabelled for research purposes. Synonym: polyvinylpyrrolidone-iodine complex, povidone-iodine. Pharmacological action: anti-infective agents, local, iodophors. Chemical name: 2-Pyrrolidinone, 1-ethenyl-, homopolymer, compd. With iodine (20 Sep 2002) |
| H-2 complex | <immunology> A term that denotes the genes of the mouse equivalent of the human major histocompatibility complex system. It is a set of genetic loci coding for Class I and Class II major histocompatibility complex antigens and for complement components. See: histocompatability antigen. (20 Jun 2000) |
