cyclosteroids |
Steroid derivatives in which one or more bridges is formed between carbon atoms at any locant in any of the rings. (12 Dec 1998) |

cyclothiazide |
6-Chloro-3,4-dihydro-3-(2-norbornen-5-yl)-2H-1,2,4-benzothiadiazine-7-sulfonamide 1,1-dioxide;a diuretic and antihypertensive. (05 Mar 2000) |
cyclothymia |
A mental disorder characterised by marked swings of mood from depression to hypomania but not to the degree that occurs in bipolar disorder. Origin: cyclo-+ G. Thymos, rage (05 Mar 2000) |
cyclothymiac |
Cyclothymic Relating to cyclothymia. (05 Mar 2000) |
cyclothymic disorder |
An affective disorder characterised by periods of depression and hypomania. These may be separated by periods of normal mood. (12 Dec 1998) |
cyclothymic personality |
A personality disorder in which a person experiences regularly alternating periods of elation and depression, (see bipolar illness) usually not related to external circumstances or situation. (27 Sep 1997) |
cyclothymic personality disorder |
A personality disorder in which a person experiences regularly alternating periods of elation and depression, (see bipolar illness) usually not related to external circumstances or situation. (27 Sep 1997) |
cyclotomy |
Operation of cutting the ciliary muscle. Origin: cyclo-+ G. Tome, incision (05 Mar 2000) |
cyclotorsion |
Rotation of the eye around its visual axis. Synonym: circumduction, cyclotorsion. Origin: cyclo-+ L. Duco, pp. Ductus, to draw (05 Mar 2000) |
cyclotron |
<radiobiology> Particle accelerator in which a magnetic field causes particles to orbit in circles, and an oscillating electric field accelerates the particles. (09 Oct 1997) |
cyclotron frequency |
<radiobiology> Number of times per second that a particle orbits a magnetic field line. The frequency is completely determined by the strength of the field and the particle's charge-to-mass ratio. (Often, and incorrectly, called the Larmor frequency. The cyclotron or gyrofrequency is twice the Larmor frequency of precession.) (09 Oct 1997) |
cyclotron radius |
<radiobiology> Radius of orbit of charged particle about a magnetic field line. Synonym: gyroradius, Larmor radius. (09 Oct 1997) |
cyclotron resonance |
<radiobiology> Charged particles in a magnetic field resonate with (and absorb energy from) an electric field (perpendicular to the magnetic field) which oscillates at the particles' cyclotron frequency, or at a harmonic (multiple) of that frequency. (09 Oct 1997) |
cyclotrons |
Devices for accelerating charged particles in a spiral path by a constant-frequency alternating electric field. This electric field is synchronised with the movement of the particles in a constant magnetic field. (12 Dec 1998) |
cyclotropia |
A disparity of ocular position in which one eye is rotated around its visual axis, with respect to the other eye. Origin: cyclo-+ G. Trope, a turn, turning (05 Mar 2000) |
