| cyclin-dependent kinases | Protein kinases that control cell cycle progression in all eukaryotes and require physical association with cyclins to achieve full enzymatic activity. Cyclin-dependent kinases are regulated by phosphorylation and dephosphorylation events. (12 Dec 1998) |
|---|---|
| cyclins | Regulatory proteins that function in the cell cycle to activate maturation-promoting factor. They complex with p34cdc2 (protein p34cdc2), the catalytic subunit of maturation-promoting factor, and modulate its protein kinase activity. Cyclins themselves have no enzymatic activity. (12 Dec 1998) |
| cyclitis | Inflammation of the ciliary body. Origin: G. Kyklos, circle (ciliary body), + -itis, inflammation (05 Mar 2000) |
| cyclization | Changing an open-chain hydrocarbon to a closed ring. (12 Dec 1998) |
| cyclizine | <chemical> A histamine h1 antagonist given by mouth or parenterally for the control of postoperative and drug-induced vomiting and in motion sickness. Pharmacological action: antiemetics, histamine h1 antagonists. Chemical name: Piperazine, 1-(diphenylmethyl)-4-methyl- (12 Dec 1998) |
| cyclizine hydrochloride | 1-Diphenylmethyl-4-methylpiperazine hydrochloride;an antihistamine agent useful in the prevention and relief of motion sickness and symptoms caused by vestibular disorders. (05 Mar 2000) |
| cyclizine lactate | An agent with the same use and action as the hydrochloride. (05 Mar 2000) |
| cyclo- | 1. Combining forms relating to a circle or cycle; or denoting an association with the ciliary body. 2. In chemistry, a combining form indicating a continuous molecule, without end, or the formation of such a structure between two parts of a molecule. Origin: G. Kyklos, circle (05 Mar 2000) |
| cyclobenzaprine hydrochloride | 1-Propanamine, 3-(5H-dibenzo[a,d]cyclohepten-5-ylidene)-N,N-diemthyl-, hydrochloride;a centrally acting skeletal muscle relaxant used to relieve acute muscular spasms. (05 Mar 2000) |
| cyclocephaly | Synonym: cyclencephaly. Origin: cyclo-+ G. Kephale, head (05 Mar 2000) |
| cyclochoroiditis | Inflammation of the ciliary body and the choroid. (05 Mar 2000) |
| cyclocryotherapy | Transscleral freezing of the ciliary body in the treatment of glaucoma. (05 Mar 2000) |
| cyclocumarol | 4-Hydroxycoumarin anticoagulant No. 63; a synthetic anticoagulant compound, related to bishydroxycoumarin. (05 Mar 2000) |
| cyclodestructive | Relating to a procedure designed to damage the ciliary body in order to diminish the production of aqueous fluid in patients with glaucoma. See: cyclocryotherapy, cyclodiathermy, cyclophotocoagulation. (05 Mar 2000) |
| cyclodextrin | <protein> A cyclic oligomer of alpha-D-glucopyranose. The most common cyclodextrinsare alpha, beta and gamma cyclodextrin having 6, 7 and 8 glucopyranoseunits respectively. They occur naturally in starch digests of the bacteria Bacillus Macerans. With a hydrophobic interior cavity, they can complex small hydrophobic molecules while remaining solublein water. Potential applications include water-soluble pharmaceuticals and herbicides and pesticides. (09 Oct 1997) |
