| ribosome-lamella complex | A cylindrical cytoplasmic inclusion composed of concentrically arranged sheets of membranes alternating with rows of ribosomes; characteristic of the hairy cell in leukaemic reticuloendotheliosis. (05 Mar 2000) |
|---|---|
| persecution complex | A feeling that others have evil designs against one's well-being. (05 Mar 2000) |
| met repressor operator complex | Repressor protein, 104 residues, product of the metJ gene, which regulates methionine biosynthesis in E. Coli. Dimeric molecules bind to adjacent sites 8 base pairs apart on the DNA, sequence recognition is by interaction between antiparallel strands of protein and the major groove of the B form DNA duplex. (18 Nov 1997) |
| Meyenburg's complex | Clusters of small bile ducts occurring in polycystic livers, separate from the portal areas. (05 Mar 2000) |
| Michaelis complex | Binary complex of an enzyme. (05 Mar 2000) |
| monophasic complex | A complex in the electrocardiogram that is entirely negative or entirely positive. (05 Mar 2000) |
| mother superior complex | The tendency of a psychotherapist to play a mothering role to the detriment of the therapeutic process. (05 Mar 2000) |
| complement membrane attack complex | The assembly of complement plasma glycoproteins c5b, c6, c7, c8, and polymeric c9 as a group on biological membranes. The complex forms transmembrane channels which displace lipid molecules and other constituents, thus disrupting the phospholipid bilayer of target cells leading to cell lysis by osmotic leakage. The formation of the membrane attack complex is the terminal step in the complement cascade. (12 Dec 1998) |
| complex | Complicated, not simple. Origin: L. Complexus = woven together, encompassing (18 Nov 1997) |
| complex carbohydrate | <biochemistry> The combination of carbohydrates and fibre. (05 Jan 1998) |
| complex closure | <surgery, technique> A sutural repair that may involve multi-layered closure, debridement or advanced tissue repair (plasty). (05 Jan 1998) |
| complex febrile convulsion | A febrile convulsion that is prolonged (greater than 15 minutes' duration) or is associated with focal neurological deficits. (05 Mar 2000) |
| complex ion | The colour, texture, and general appearance of the skin of the face. Origin: L. Complexio, a combination, (later) physical condition (05 Mar 2000) Previous: complex carbohydrate, complex closure, complex febrile convulsion, complexinNext: complex ion, complexity, complex learning processescomplex ion <chemistry> An ion formed by the combination of a central metal ion and ligands. (05 Jan 1998) |
| complex learning processes | Those process's that require the use of symbolic manipulations, as in reasoning. (05 Mar 2000) |
| 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) |
