| Dane, D | <person> 20th century British virologist. See: Dane particles. (05 Mar 2000) |
| dane particle | <virology> 42 nm spherical particle, the complete infective virion of hepatitis B containing a 27 nm core antigen. (27 Sep 1997) |
| Dane's stain | <technique> A stain for prekeratin, keratin, and mucin which employs haemalum, phloxine, Alcian blue, and orange G; nuclei appear orange to brown, acid mucopolysaccharides pale blue, and keratins orange to red-orange. (05 Mar 2000) |
| alpha particles | Positively charged particles composed of two protons and two neutrons, i.e., helium nuclei, emitted during disintegration of very heavy isotopes; a beam of alpha particles or an alpha ray has very strong ionizing power, but weak penetrability. (12 Dec 1998) |
| chromatin particles | Fine bluish dots thought to represent remnants of the nucleus, occasionally seen in stained erythrocytes. (05 Mar 2000) |
| submitochondrial particles | The various filaments, granules, tubules or other inclusions within mitochondria. (12 Dec 1998) |
| electron transport particles | <cell biology> Fragments of mitochondria still capable of transporting electrons. One of the units occurring on the matrical surface of mitochondrial cristae; the head of the particle which measures about 9 nm, attaches to the membrane of the crista by a stalk 5 nm in length; the particle may be concerned with the electron transport system. Synonym: submitochondrial particles. (05 Mar 2000) |
| elementary particles | <radiobiology> at a nuclear-energy level: electron & positron - seem to be stable, proton - thought to be stable, life greater than 10^30 sec, neutron - decays in ?6 min unless its in a nucleus, which often extends its life. Other particles important for nuclear energy: Muon, neutrino (m, e, tau), photon, Muonic atoms, Pi-meson antiparticles (09 Oct 1997) |
| kappa particles | Inheritable cytoplasmic symbionts, once thought to be particle's mainly or exclusively of DNA, occurring in some strains of Paramecium; capable of producing a product lethal to other strains. (05 Mar 2000) |
