Chemical reaction
|
|
Chemical reactionA process in which one substance is transformed into another. Thousands of different types of chemical reactions occur in the body and are essential to its structure and function.
RELATED TERMS--------------------------------------
Essential
1. Something that cannot be done without. 2. Required in the diet, because the body cannot make it. As in an essential amino acid or an essential fatty acid. 3. Idiopathic. As in essential hypertension.
SIMILAR TERMS--------------------------------------
Chemet
Chemet is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries. Active ingredient(s): succimer.
Chemical menopause
Menopause induced by chemotherapy or other chemicals or medications.
Chemo
Slang for chemotherapy -- drug therapy for cancer.
Chemobrain
Cognitive dysfunction associated with chemotherapy. It is thought that chemotherapy may cause memory loss, attention loss, and other problems that make it difficult for patients to think clearly. Also known as chemo-brain, chemo-fog, and chemotherapy-related cognitive dysfunction.
Chemoembolization
A procedure in which the blood supply to a tumor is blocked and anticancer drugs are administered directly into the tumor, permitting a much higher concentration of drugs to be in contact with the tumor for a longer period of time, while depriving the tumor of oxygen and nutrients. The procedure is used to treat cancer originating in the liver (primary liver cancer) as well as cancer that has metastasized (spread) to the liver from another area.
Chemokine
One of a large group of proteins that act as lures and were first found attracting white blood cells. The chemokines are involved in a wide variety of processes including acute and chronic types of inflammation, infectious diseases, and cancer. Chemokines may lure cancer cells and help determine the sites to which cancer cells spread by metastasis.
Chemokine receptor
A molecule that receives a chemokine and a chemokine dock.
Chemokinesis
The response of a cell to a chemical that causes the cell to make some kind of change in its movement by speeding it up, slowing it down or changing its direction. The molecules that achieve these results are called chemokines.
Chemoprevention
The use of natural or laboratory-made substances to prevent a disease such as cancer. The regular use of aspirin is known to reduce the risk of the polyps from which colorectal cancer arises. This is an instance of chemoprevention. The term chemoprevention was coined to parallel the term chemotherapy. Chemoprevention prevents and chemotherapy treats. Chemoprevention is also called chemoprophylaxis.
Chemoprophylaxis
Prevention of disease by the use of chemicals or drugs.
Chemoradiotherapy
The combination of simultaneous chemotherapy and radiation therapy. Chemoradiotherapy before surgery has been found to reduce the risk of local recurrence of rectal cancer.
Chemosense
The chemical sensing system. The sense of smell is part of our chemical sensing system, or the chemosenses.
Chemosis
Swelling around the iris (the colored circle that surrounds the pupil) due to edema (swelling) of the bulbar conjunctiva (the clear membrane that coats the outer surface of the eye).
Chemotaxis
The movement of cells in response to chemical messengers. The movement of neutrophils and macrophages into damaged tissues is brought about by signals released by damaged tissues, and bacterial products. The term applies to the movement of any organism attracted by a specific chemical, which may be a suitable nutrient.
Chemotherapy
The use of chemicals (medicines) to treat cancer.
Chemotherapy, adjuvant
Chemotherapy (drug therapy) that is given after tumor surgery.
Chemotherapy, topical
Treatment with an anticancer drug in a lotion, ointment or cream that is applied to the skin.
PREVIOUS AND NEXT TERMS--------------------------------------
CHD
Congenital heart disease, a malformation of the heart or the large blood vessels near the heart. The term "congenital" speaks only to time, not to causation; it means "born with" or "present at birth."
Checkpoint
A surveillance system responsible for monitoring the proper completion of an event within a cell. Cells contain a number of such systems. When a checkpoint system detects the failure of an event, it signals and calls for the inhibition of events downstream to the failure. These surveillance systems are termed checkpoints because they represent stages in the cell cycle at which the cell checks to be certain it is okay to proceed. Checkpoints control the order and timing of cell cycle transitions and ensure that critical events, such as DNA replication and chromosome segregation, are completed with high fidelity.
Cheek
The side of the face forming the side wall of the mouth. The cheek bone is part of the temporal bone of the skull that provides the prominence of the cheek.
Cheilitis
Inflammation of the lips or of a lip.
Chemical menopause
Menopause induced by chemotherapy or other chemicals or medications.
