Possible definitions for zyxin
auxin
Any of a group of hormones that regulate plant growth, particularly by stimulating cell elongation in stems and inhibiting it in roots. Auxins influence the growth of stems toward light (phototropism) and against the force of gravity (geotropism). Auxins also play a role in cell division and differentiation, fruit development, the formation of roots from cuttings, the inhibition of lateral branching, and leaf fall. The most important naturally occurring auxin is beta-indolylacetic acid.
boxing
Sport involving attack and defense with the fists. In the modern sport, boxers wear padded gloves and fight bouts of up to 15 three-minute rounds in a three-roped square ring. In ancient Greece fighters used leather thongs on their hands and forearms, while in Rome gladiators used metal-studded leather hand covering (cesti) and usually fought to the death. Not until implementation of the London Prize Ring rules in 1839 were kicking, gouging, butting, biting, and blows below the belt eliminated from the boxer's standard repertoire. In 1867 the Queensberry rules called for the wearing of gloves, though bareknuckle boxing continued into the late 1880s. The last of the great bareknuckle fighters was J. L. Sullivan. From Sullivan on, the U.S. became the premier boxing venue, partly because immigrants supplied a constantly renewed pool of boxers. Boxing has been included among the Olympic Games since 1904. Today there are seven primary weight classes: flyweight, to 112 lbs (51 kg); bantamweight, to 118 lbs (53 kg); featherweight, to 126 lbs (57 kg); lightweight, to 135 lbs (61 kg); welterweight, to 147 lbs (67 kg); middleweight, to 160 lbs (72 kg); light heavyweight, to 175 lbs (79 kg); and heavyweight, over 175 lbs. A bout can be won either by knocking out or felling one's opponent for a count of 10 (a KO) or by delivering the most solid blows and thus amassing the most points. The referee can also stop the fight when one boxer is being badly beaten (a technical knockout, or TKO) or he can disqualify a fighter for rules violations and award the fight to his opponent.
bylina
Traditional form of orally transmitted Old Russian and Russian heroic narrative poetry. Though byliny originated about the 10th cent., or possibly earlier, they were first written down around the 17th cent. They have been classified into several groupings, the largest of which deal with the golden age of Kiev in the 10th-12th cent. Taken together, they constitute a folk history often at variance with official history.
lysine
One of the essential amino acids, present in many common proteins. Its proportion in the proteins of some important food plants (incl. wheat and corn) is so small that populations dependent on these grains as the sole source of dietary protein suffer from lysine deficiency, affecting growth in children and general well-being in adults. It is used in biochemical and nutritional research, in ...
