To try is the generic, to attempt is the specific, term. When we try, we are usually uncertain as to success; when we attempt, we have always some definite object in view which we seek to accomplish. We may be indifferent as to the result of a trial, but we rarely attempt anything without a desire to succeed. "He first deceased: she for a little tried To live without him; liked it not, and died." (Sir H. Wotton) "Alack, I am afraid they have a waked, And 't is not done. The attempt, and not the deed, Confounds us." (Shak) Origin: OE. Trien to select, pick out, F. Trier to cull, to out, LL. Tritare to triturate (hence the sense of, to thresh, to separate the grain from the straw, to select), L. Terere, tritum, to rub, bruise, grind, thresh. See Trite.

| Trypanosoma | <protozoa> Genus of Protozoa that causes serious infections in humans and domestic animals. African trypanosomes, of the brucei group, are carried by Tsetse flies and, when they enter the bloodstream of the mammalian host go through a complex series of stages. Perhaps the most interesting feature is that there are recurrent bouts of parasitaemia as the parasite alters its surface antigens to evade the immune response of the host (see antigenic variation). The repertoire of antigenic variation is considerable. The s.American trypanosomes (of which T. Cruzi is the best known) are carried by reduviid bugs and cause a chronic and incurable disease. Other interesting features of trypansomes are the kinetoplast DNA and glycosomes (organelles containing enzymes of the glycolytic chain). (18 Nov 1997) |
