|---|---|
| IGHD | immunoglobin delta heavy chain; isolated growth hormone deficiency |
| IGHE | immunoglobulin epsilon heavy chain |
| IGHV | immunoglobulin heavy chain variable region |
| ITIH2 | inter-alpha-trypsin inhibitor, heavy chain 2 |
| submitochondrial particle | Formed by sonicating mitochondria. Small vesicles in which the inner mitochondrial membrane is inverted to expose the innermost surface. (18 Nov 1997) |
|---|---|
| dane particle | <virology> 42 nm spherical particle, the complete infective virion of hepatitis B containing a 27 nm core antigen. (27 Sep 1997) |
| defective interfering particle | An incomplete virus that is unable to replicate and interferes with replication of an infectious virus. (05 Mar 2000) |
| D.I. particle | <abbreviation> Defective interfering particle. (05 Mar 2000) |
| dressed particle | <radiobiology> A particle plus its associated neutralising Debye sphere. (09 Oct 1997) |
| intramembranous particle | <cell biology> Particles (or complementary pits) seen in freeze fractured membranes. The cleavage plane is through the centre of the bilayer and the particles are usually assumed to represent Integral membrane proteins (or polymers of such proteins). (18 Nov 1997) |
| either particle flux density | The particle fluence rate, or energy flux density, the energy fluence rate of intensity. Compare: fluence. (05 Mar 2000) |
| elementary particle interactions | The interactions of particles responsible for their scattering and transformations (decays and reactions). Because of interactions, an isolated particle may decay into other particles. Two particles passing near each other may transform, perhaps into the same particles but with changed momenta (elastic scattering) or into other particles (inelastic scattering). Interactions fall into three groups: strong, electromagnetic, and weak. (12 Dec 1998) |
| trapped-particle instability | <radiobiology> Slowly-growing class of instabilities driven by particles which cannot circulate freely in a toroidal system. See: banana orbit. (09 Oct 1997) |
| kappa particle | <microbiology> Gram-negative bacterial endosymbiont of Paramoecium spp., (Caedobacter taeniospiralis) that confers the killer trait, infected Paramoecium are resistant to the toxin liberated by infected forms. Killing activity is associated with the induction of defective phage in the endosymbiont, leading to the release of R bodies, coded for by the phage genome and apparently of mis assembled phage coat protein. (18 Nov 1997) |
| Zimmermann's elementary particle | <haematology> A discoid cell (3m diameter) found in large numbers in blood, important for blood coagulation and for haemostasis by repairing breaches (small breaks) in the walls of blood vessels. Platelet _ granules contain lysosomal enzymes, dense granules contain ADP (a potent platelet aggregating factor) and serotonin (a vasoactive amine). They also release platelet-derived growth factor which presumably contributes to later repair processes by stimulating fibroblast proliferation. Synonym: thrombocytes. (09 Oct 1997) |
