Flush
Flush (1) A redness of the skin, typically over the cheeks or neck. A flush is usually temporary and brought on by excitement, exercise, fever, or embarrassment. Flushing is an involuntary (uncontrollable) response of the nervous system leading to widening of the capillaries of the involved skin. Also referred to as a blush (or, as a verb, to blush). Flushing may also be caused by medications or other substances that cause widening of the capillaries, such as niacin. (2) Flush also means to wash out a wound or body area.

Fever

Capillaries
Tiny blood vessels between arteries and veins that distribute oxygen-rich blood to the body.

Niacin
One of the B vitamins, niacin is an essential vitamin that is especiallyimportant for digestion and appetite, as well as tissue and nerve cells.
Wound
A wound is a physical trauma where the skin is torn, cut or punctured. Exposed to air, there is not only a significant chance of death due to loss of blood, but increased chance of bacteria entering the wound or an infection.

Fluoride
A compound of fluorine with another element or radical. Fluoride compounds are present in drinking water and some foods. Fluoride ions replace hydroxyl ions in hydroxyapatite in teeth, forming fluorapatite, which leads to fewer cavities. Fluoride compounds are therefore added to some toothpastes and dentists may also give a yearly fluoride treatment. It is generally recommended that fluorides be added to water supplies in which the natural level is less than 0.7 ppm in water to increase the concentration to 0.7-1.2 ppm. The addition of fluoride to water systems is one of the major achievements in public health in the 20th century. Fluoride, in combination with calcium and vitamin D, also increases bone mass and lowers the risk of backbone fractures associated with osteoporosis. The only accepted adverse effect of fluoridation is dental fluorosis.
Fluorobody
A hybrid molecule that combines the affinity and specificity of an antibody with the visibility of a green fluorescent protein (GFP). The GSP provides the antibody with a built-in detection system.
Fluoroscopy
An x-ray procedure that makes it possible to see internal organs in motion. Fluoroscopy uses x-ray to produce real-time video images. After the x-rays pass through the patient, instead of using film, they are captured by a device called an image intensifier and converted into light. The light is then captured by a TV camera and displayed on a video monitor.
Fluorosis
An abnormal condition caused by excessive intake of fluorine, characterized chiefly by mottling of the teeth.
Fluorouracil
A much-used anticancer drug that belongs to the family of drugs called antimetabolites. Full name: 5-fluorouracil. Abbreviation: 5-FU. 5-FU is a pyrimidine antagonist. 5-FU is similar in structure to the pyrimidine base thymine and functions to inhibit DNA synthesis both by blocking the formation of normal pyrimidine nucleotides via both enzyme inhibition and by interfering with DNA synthesis after incorporation into a growing DNA molecule. 5-FU is also able to block the production of RNA and thereby induce cell death. 5-FU affects the processing of messenger RNA (mRNA), ribosomal RNA (rRNA), transfer RNA (tRNA), and small nuclear RNA (snRNA). 5-FU may also inhibit cell growth is through its ability to prevent the synthesis of thymine nucleotides from uracil nucleotides.
Flush
Flutter, atrial
Well-organized but overly rapid contractions of the atrium of the heart (usually at a rate of 250-350 contractions per minute).
Flying, fear of
An irrational fear of flying is called aerophobia. Aerophobia also refers to irrational fear of fresh air or drafts of air. A virtual reality program that simulates the experience of take-offs, landings, normal flying and turbulence reportedly helps some people overcome their fear of flying.
FMDV
Foot-and-mouth disease virus.
FMF (familial Mediterranean fever)
An inherited disorder featuring short recurring crises of severe abdominal pain and bouts of fever. Other symptoms include arthritis, chest pain from inflammation of the lung cavity, and skin rashes. Between attacks, the patient seems healthy. Amyloidosis (the abnormal deposition of a particular protein, called amyloid, in various tissues of the body) is a potentially serious complication and can develop without overt attacks of FMF. The kidney is a prime target for the amyloid.
FMO3
Abbreviation for the enzyme, flavin-containing monooxygenase-3.
