Homocysteine
Homocysteine A product which is found naturally when a particular amino acid is broken down. It is associated with ageing, folate levels, vitamin B deficiencies and possibly renal dysfunction. Higher concentration of homocysteine in plasma is regarded as a risk factor for cardiovascular disease.
RELATED TERMS--------------------------------------
Folate
Folic acid, one of the B vitamins that is a key factor in the synthesis (the making) of nucleic acid (DNA and RNA). A deficiency of folic acid after birth causes a kind of anemia, namely, megaloblastic anemia in which there is a paucity of red blood cells and those that are made are unusually large and immature (so-called blast cells).
Vitamin
Any of many organic substances that are vital in small amounts to the normal functioning of the body. Vitamins are found in food, produced by the body, and manufactured synthetically; along with minerals, they are known as micronutrients.
Renal
Pertains to kidneys.
Dysfunction
Difficult function or abnormal function.
Homocysteine
A product which is found naturally when a particular amino acid is broken down. It is associated with ageing, folate levels, vitamin B deficiencies and possibly renal dysfunction. Higher concentration of homocysteine in plasma is regarded as a risk factor for cardiovascular disease.
Plasma
The watery, liquid part of the blood in which the red blood cells, the white blood cells, and platelets are suspended.
Risk
In clinical trials, the probability of harm or discomfort for subjects, arising from the test product. Acceptable risk differs depending on the condition for which a product is being tested. A product for sore throat, for example, will be expected to have a low incidence of side effects. However, unpleasant side effects may be an acceptable risk when testing a promising treatment for a life-threatening illness.
Cardiovascular
Of, relating to, or involving the heart and the blood vessels.
Disease
Illness or sickness often characterized by typical patient problems (symptoms) and physical findings (signs). Disruption sequence: The events that occur when a fetus that is developing normally is subjected to a destructive agent such as the rubella (German measles) virus.

Homophilia
The condition in which love, lust, and pairbonding are directed and attached primarily to those of the same sex. A condition of being in which sexuoerotic arousal and facilitation or attainment of orgasm are responsive to, and dependent upon a partner of the same morphologic sex [from Greek, homos, same + -philia]. Homophilia may exist only in ideation and affect or in combination with sexual behavior in some homosexuality.
Homophobia
The condition in which those whose love and lust are attached to others of the same sex are dreaded or feared pathological fear of homosexualism. It is not itself a paraphilia, but may be associated with one, as in homophobic lust murder [from Greek, homos, same + phobos, fear or fright].

Homosexual
Characterized by same-sex contact, either as a genital act or as a long-term sexuoerotic status [from Greek, homos, same + sex]. It is analogous to left-handedness in being not pathological in itself, though not conforming to the statistical nor the ideological norm, and not being exempt from other pathology. A homosexual person is able to fall in love with, and become the pairbonded sexuoerotic partner of only a person of the same morphologic sex (homophilic homosexual). Homosexuality is not a paraphilia but a gender transposition, variable in extent and degree. Paraphilias may occur in association with either homosexual or heterosexual pairing.
Homosexualism
Synonym, homosexuality.
Homosexuality
Erotosexual pairing with a partner of the same genital morphology. Its full manifestation includes falling in love (homophilic limerence).
