flavin

 [fla´vin]
any of a group of water-soluble yellow pigments widely distributed in animals and plants, including riboflavin and yellow enzymes.
flavin adenine dinucleotide (FAD) a coenzyme that is a condensation product of riboflavin phosphate and adenylic acid; it forms the prosthetic group (non–amino acid component) of certain enzymes, including d-amino acid oxidase and xanthine oxidase, and is important in electron transport in mitochondria.
flavin mononucleotide (FMN) a derivative of riboflavin consisting of a three-ring system (isoalloxazine) attached to an alcohol (ribitol); it acts as a coenzyme for a number of oxidative enzymes, including l-amino acid oxidase and cytochrome C reductase.

BRCA2

A gene on chromosome 13q12.3 that encodes a protein which, like BRCA1, is involved in maintenance of genome stability, especially the homologous recombination pathway for double-stranded DNA repair; like BRCA1, it carries a marked increase in the lifetime risk of breast and ovarian cancer.

FAD

Abbreviation for flavin adenine dinucleotide.

FAD (flavin adenine dinucleotide)

an electron carrier similar in action to NAD, picking up hydrogen from succinic acid (succinate) in the KREBS CYCLE. The hydrogen is transported to the mitochondrial cristae where it enters an ELECTRON TRANSPORT SYSTEM at a lower point than NAD, with the release of only two molecules of ATP (rather than three ATP molecules when NAD is the carrier).

FAD

Abbreviation for flavin adenine dinucleotide.

The drastic (82.74%) [TOF.sub.fade] caused by cisatracurium seems to exhibit an amount of adenosine in the synaptic cleft which might be lower than that extant during 100% Fade, as at 50 Hz there is a higher activation of presynaptic [M.sub.1] receptors by acetylcholine.
In contrast, for the first time it is being shown that the simultaneous blockages of [M.sub.1] and [M.sub.2] presynaptic receptors by atropine seem to be more efficient than blockage of [A.sub.2A] receptors to reduce the Fade caused by cisatracurium.
where A is attenuation and [DELTA]t is the time interval length over which fade slope is calculated.
Key information of first and second order statistics (i.e., long term rain attenuation CCDF, fade duration, and fade slope) has been extracted and analyzed.
Not quite trusting the advice, Peters felt I had 'held on' to my first few efforts, not breaking my wrists and trying to steer the ball back towards the target, all of which resulted in an immediate push, then a fade.
However, in practice, for systems operating with 30 kHz or even 200 kHz channel spacing, it is necessary to switch frequency by many channels to overcome a fade. This degree of redundancy can lead to up to a 50 percent reduction in network capacity and so is not used widely.
You also should pay special attention to vessel buildup, plugging of the inductor, Mg fade resulfurization of the iron, restarting your pressure pour and changing alloys.
Unfortunately, rotary impeller degassing can speed the fade and dissipation of strontium and boron in molten aluminum.
The differences in the structure and mechanical properties between the first and second set of castings poured involved temperature loss and inoculant fade. The lower temperature caused the castings to solidify faster, resulting in some undercooling.
Five photos titled Barbershop Fade (all works 2012) demonstrate this well.
