| spin labelling | <chemistry, technique> The technique of introducing a grouping with an unpaired electron to act as an electron spin resonance (ESR) reporter species. This is almost invariably a nitroxide compound (N O) in which the nitrogen forms part of a sterically hindered ring. (18 Nov 1997) |
|---|---|
| spin labels | Molecules which contain an atom or a group of atoms exhibiting an unpaired electron spin that can be detected by electron spin resonance spectroscopy and can be bonded to another molecule. (12 Dec 1998) |
| spin-spin relaxation | In nuclear magnetic resonance, the return of the magnetic dipoles of the hydrogen nuclei (magnetization vector) to equilibrium parallel to the magnetic field, after they have been flipped 90 |
|---|---|
| radio label | A mildly radioactive molecule that is used to tag another molecule (such as a protein) so that it can be identified as it goes through some kind of biochemical process. (09 Oct 1997) |
| chromogenic label | A molecule which can be used as a label to a biological probe molecule because it forms a coloured compound when the probe molecule is attached to its target. (09 Oct 1997) |
| off-label | Use of a drug for a disease or condition other than the indication for which it was approved by the FDA. For example: many doctors prescribe paromomycin (humatin) for cryptosporidiosis, although it is not approved for treating this disease. (09 Oct 1997) |
| off-label use | In the United States, the regulations of the Food and drug administration (FDA) permit physicians to prescribe approved medications for other than their intended indications. This practice is known as off-label use. (12 Dec 1998) |
| open-label trial | A study in which both researchers and participants know what drug a person is taking and at what dose. (09 Oct 1997) |
| label | 1. To incorporate into a compound a substance that is readily detected, such as a radionuclide, whereby its metabolism can be followed or its physical distribution detected. 2. The substance so incorporated. (05 Mar 2000) |
| fluorescent label | A molecule which fluoresces and can be attached to a probe molecule that does not fluoresce. (09 Oct 1997) |
| spin | 1. To practice spinning; to work at drawing and twisting threads; to make yarn or thread from fibre; as, the woman knows how to spin; a machine or jenny spins with great exactness. "They neither know to spin, nor care to toll." (Prior) 2. To move round rapidly; to whirl; to revolve, as a top or a spindle, about its axis. "Round about him spun the landscape, Sky and forest reeled together." (Longfellow) "With a whirligig of jubilant mosquitoes spinning about each head." (G. W. Cable) 3. To stream or issue in a thread or a small current or jet; as, blood spinsfrom a vein. 4. To move swifty; as, to spin along the road in a carriage, on a bicycle, etc. 1. To draw out, and twist into threads, either by the hand or machinery; as, to spin wool, cotton, or flax; to spin goat's hair; to produce by drawing out and twisting a fibrous material. "All the yarn she [Penelope] spun in Ulysses' absence did but fill Ithaca full of moths." (Shak) 2. To draw out tediously; to form by a slow process, or by degrees; to extend to a great length; with out; as, to spin out large volumes on a subject. "Do you mean that story is tediously spun out?" (Sheridan) 3. To protract; to spend by delays; as, to spin out the day in idleness. "By one delay after another they spin out their whole lives." (L'Estrange) 4. To cause to turn round rapidly; to whirl; to twirl; as, to spin a top. 5. To form (a web, a cocoon, silk, or the like) from threads produced by the extrusion of a viscid, transparent liquid, which hardens on coming into contact with the air; said of the spider, the silkworm, etc. 6. <mechanics> To shape, as malleable sheet metal, into a hollow form, by bending or buckling it by pressing against it with a smooth hand tool or roller while the metal revolves, as in a lathe. To spin a yarn, to twist it into ropes for convenient carriage on an expedition. To spin street yarn, to gad about gossiping. Origin: AS. Spinnan; akin to D. & G. Spinnen, Icel. & Sw. Spinna, Dan. Spinde, Goth. Spinnan, and probably to E. Span. Cf. Span, Spider. 1. The act of spinning; as, the spin of a top; a spin a bicycle. 2. <physics> Velocity of rotation about some specified axis.

| spin-polarized fusion | <radiobiology> A method to enhance nuclear fusion reaction rates in some fusion fuels by polarizing the nuclear spins. (09 Oct 1997) |
| spin trapping | A technique for detecting short-lived reactive free radicals in biological systems by providing a nitrone or nitrose compound for an addition reaction to occur which produces an electron spin resonance spectroscopy-detectable aminoxyl radical. In spin trapping, the compound trapping the radical is called the spin trap and the addition product of the radical is identified as the spin adduct. (free rad res comm 1990;9(3-6):163) (12 Dec 1998) |
| electron spin resonance | <physics> A spectrometric method, based on measurement of electron spins and magnetic moments, for detecting and estimating free radicals in reactions and in biological systems. Synonym: electron paramagnetic resonance. (05 Mar 2000) |
