Halos
(gcide) | Halo \Ha"lo\ (h[=a]"l[-o]), n.; pl. Halos (-l[=o]z). [L.
halos, acc. halo, Gr. "a`lws a thrashing floor, also (from
its round shape) the disk of the sun or moon, and later a
halo round it; cf. Gr. e'ily`ein to enfold, 'ely`ein to roll
round, L. volvere, and E. voluble.]
1. A luminous circle, usually prismatically colored, round
the sun or moon, and supposed to be caused by the
refraction of light through crystals of ice in the
atmosphere. Connected with halos there are often white
bands, crosses, or arches, resulting from the same
atmospheric conditions.
[1913 Webster]
2. A circle of light; especially, the bright ring represented
in painting as surrounding the heads of saints and other
holy persons; a glory; a nimbus.
[1913 Webster]

4. A colored circle around a nipple; an areola.

birds belonging to Parus and allied genera; -- called also

cephalosporin
(gcide) | Lactam \Lac"tam\, n. [Lactone + amido.] (Chem.)
One of a series of anhydrides of an amido type, analogous to
the lactones, as oxindol; a cyclic amide.
[1913 Webster]
beta-lactam or [beta]-lactam,
(a) a lactam in which the amide bond is contained within a
four-membered ring, which includes the amide nitrogen and
the carbonyl carbon.
(b) an antibiotic containing a beta-lactam, such as a
penicillin, cephalosporin, or carbapenem; also
called a beta-lactam antibiotic. [informal, laboratory
slang]
[PJC]Cephalosporin \Ceph"a*lo*spor`in\
(s[e^]f"[.a]*l[-o]*sp[=o]r`[i^]n), n. [from Cephalosporium, a
fungus producing the first of the series discovered.] (Chem.)
any of a class of chemical substances, some of which have
therapeutically useful antibacterial activity, whose
structure contains a beta-lactam ring fused to a six-membered
ring containing a sulfur and a nitrogen atom. The first of
the series, cephalosporin C, was discovered by G. Brotzu in
1955 in the culture broth of a Cephalosporium species found
off the coast of Sardinia. Other cephalosporins have been
found to be produced by species of soil bacteria
(actinomycetes). Many semisynthetic analogs have been tested
for antibacterial effect, and several of them have found use
as important clinically useful antibacterial agents, some of
which may be taken orally for treatment of bacterial
infections. The cephalosporins are the second class of
beta-lactam antibiotic to be discovered, the first being the
penicillins and more recent classes being the
thienamycins and sulfazecins. The cephamycins are a
variant of cephalosporins with a methoxyl group on the
beta-lactam ring, rendering them more resistant to
penicillinases. Among the cephalosporins which have been
found clinically useful are cephalexin, cephaloridine,
and cephalothin.
