| GTS | Gilles de la Tourette syndrome; glucose transport system |
|---|---|
| HAChT | high affinity choline transport |
| HTL | hamster tumor line; hearing threshold level; high-L-leucine transport; histotechnologist; human T-ce... |
| HTR | histidine transport regulator; 5-hydroxytryptamine receptor |
| IVOTTS | Irvine viable organ-tissue transport system |
| 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) |

| electron transport phosphorylation | <biochemistry> Synthesis of ATP involving a membrane associated electron transport chain and the creation of a proton-motive force. (09 Oct 1997) |
| electron transport system | The mitochondrial electron transport chain. (18 Nov 1997) |
| transcellular transport | Solute movement across an epithelial cell layer through the cells. Compare: paracellular transport. (05 Mar 2000) |
| transport | <radiobiology> Refers to processes which cause heat energy, or particles, or something else, to flow out of the plasma and cease being confined. Diffusion partly determines the rate of transport. Energy losses from a plasma due to transport processes are a central problem in fusion energy research. See: classical transport, neoclassical transport, anomalous tranport, diffusion, ambipolar diffusion, Bohm diffusion, classical diffusion, neoclassical diffusion, anomalous diffusion, energy transport, ripple transport. (09 Oct 1997) |
| transport antibiotic | A substance that makes biomembranes permeable to certain ions. (05 Mar 2000) |
| transport diseases | Single gene defect diseases in which there is an inability to transport particular small molecules across membranes. Examples are aminoacidurias such as cystinuria, iminoglycinuria, Hartup disease, Fanconi disease. (18 Nov 1997) |
| transport host | An intermediate host in which no development of the parasite occurs, although its presence may be required as an essential link in the completion of the parasite's life cycle; e.g., the successive fish host's that carry the plerocercoid of Diphyllobothrium latum, the broad fish tapeworm, to larger food fish eventually eaten by man or other final host's. Synonym: transport host. (05 Mar 2000) |
| transport medium | A medium for transporting clinical specimens to the laboratory for examination. (05 Mar 2000) |
| transport number | The fraction of the total current carried through a solution by a particular type of ion present in that solution. (05 Mar 2000) |
| transport protein | <protein> A class of transmembrane protein that allows substances to cross plasma membranes far faster than would be possible by diffusion alone. A major class of transport proteins expend energy to move substances (active transport), these are transport ATPases. See: facilitated diffusion, symport, antiport. (18 Nov 1997) |
| transport tetany | An acute disease seen in cattle and sheep during and shortly after shipping; it appears most often in females in advanced pregnancy and is believed to be precipitated by stress, lack of food and water, and perhaps heat. Synonym: railroad disease, railroad sickness. (05 Mar 2000) |
| transport vesicle | <cell biology> Vesicles that transfer material from the rough endoplasmic reticulum to the receiving face of the Golgi. (18 Nov 1997) |
| facilitated transport | The protein-mediated transport of a compound across a biomembrane that is not ion-driven; a saturable transport system. Synonym: passive transport. (05 Mar 2000) |
| receptors, cytoplasmic and nuclear | Proteins in the cytoplasm or nucleus that specifically bind signalling molecules and trigger changes which influence the behaviour of cells. The major groups are the steroid hormone receptors, which usually are found in the cytoplasm, and the thyroid hormone receptors, which usually are found in the nucleus. Receptors, unlike enzymes, generally do not catalyze chemical changes in their ligands. (12 Dec 1998) |
