factor,

in arithmetic, any number that divides a given number evenly, i.e., without any remainder. The factors of 12 are 1, 2, 3, 4, 6, and 12. Similarly in algebra, any one of the algebraic expressions multiplied by another to form a product is a factor of that product, e.g., a+b and ab are factors of a2b 2, since (a+b)(ab)=a2b2. In general, if r is a rootroot,
in mathematics, number or quantity r for which an equation f(r)=0 holds true, where f is some function. If f is a polynomial, r is called a root of f; for example, r=3 and r

mathematical expression which is a finite sum, each term being a constant times a product of one or more variables raised to powers. With only one variable the general form of a polynomial is a0xn+a1x

This includes promotion of NO and endothelium-derived hyperpolarizing factor (EDHF), which may contribute to the overall antihypertensive and cardioprotective effects of polyphenol rich foods.
In addition to nitric oxide (NO) and prostacyclin, endothelial cells synthesize and release endothelium-derived hyperpolarizing factor (EDHF), which causes hyperpolarization of underlying vascular smooth muscle cells via activation of [Ca.sup.2+]-activated [K.sup.+] channels (2).
There is evidence suggesting that additional mechanisms are involved in endothelial control of vascular tone, such as prostacyclins (33,34) and endothelium-derived hyperpolarizing factor (EDHF), a cytochrome P450-derived arachidonic acid metabolite (35-37).
Vasodilation effects of EOFAZ were totally abolished by mechanical removal of the endothelium, suggesting that they are dependent upon released endothelium-derived relaxant factors such as nitric oxide (NO), PGI2 and/or endothelium-derived hyperpolarizing factor (EDHF).
