Circadian Rhythm Signaling Peptides and Proteins
|
D056925 |
[A broad category of proteins that regulate the CIRCADIAN RHYTHM of an organism. Included here are proteins that transmit intracellular and intercellular signals in a chronological manner along with proteins that sense light and time-dependent changes in the environment such as the PHOTOPERIOD.

Circuit-Based Exercise
|
D065327 |

Circulatory Arrest, Deep Hypothermia Induced
|
D050792 |
[A technique to arrest the flow of blood by lowering BODY TEMPERATURE to about 20 degrees Centigrade, usually achieved by infusing chilled perfusate. The technique provides a bloodless surgical field for complex surgeries.

Circulatory and Respiratory Physiological Phenomena
|
D002943 |
[Functional processes and properties characteristic of the BLOOD; CARDIOVASCULAR SYSTEM; and RESPIRATORY SYSTEM.

|
Circumcision, Female
|
D019093 |
[A general term encompassing three types of excision of the external female genitalia - Sunna, clitoridectomy, and infibulation. It is associated with severe health risks and has been declared illegal in many places, but continues to be widely practiced in a number of countries, particularly in Africa.

Circumcision, Male
|
D002944 |
[Excision of the prepuce of the penis (FORESKIN) or part of it.

|
Circumventricular Organs
|
D066280 |
[Highly vascularized and specialized tissues distributed principally along the midline of the VENTRICULAR SYSTEM from the FOREBRAIN to the HINDBRAIN. They are distinguished by their lack of normal BLOOD-BRAIN BARRIER and fenestrated capillaries and contain either neurosecretory neurons or chemoreceptors.

Cirsium
|
D031180 |
[A plant genus of the family ASTERACEAE. Members contain pectolinarin (a flavonoid glycoside).

|
Cisapride
|
D020117 |
[A substituted benzamide used for its prokinetic properties. It is used in the management of gastroesophageal reflux disease, functional dyspepsia, and other disorders associated with impaired gastrointestinal motility. (Martindale The Extra Pharmacopoeia, 31st ed)

|
Cisplatin
|
D002945 |
[An inorganic and water-soluble platinum complex. After undergoing hydrolysis, it reacts with DNA to produce both intra and interstrand crosslinks. These crosslinks appear to impair replication and transcription of DNA. The cytotoxicity of cisplatin correlates with cellular arrest in the G2 phase of the cell cycle.

Cistaceae
|
D030601 |
