| electron transfer flavin | <biochemistry> Flavoproteins that participate in the electron transport pathway. (05 Mar 2000) |
|---|---|
| embryo transfer | The placement of a laboratory-fertilized egg into the uterus. (09 Oct 1997) |
| transfer | The conveyance of something from one place to another. Origin: L. Ferre = to carry (18 Nov 1997) |
| transfer agreement | A written agreement for the transfer of patients and their medical records from one health care institution to another. (12 Dec 1998) |
| transfer cell | <plant biology> Parenchyma cell specialised for transfer of water soluble material to or from a neighbouring cell, usually a phloem sieve tube or a xylem tracheid. Elaborate wall ingrowths greatly increase the area of plasma membrane at the cell face across which transfer occurs. (17 Mar 1998) |
| transfer DNA | <molecular biology> The transforming region of DNA in the Ti plasmid of agrobacterium tumefaciens. Acronym: t-DNA (04 Jul 1999) |
| transfer factor | A dialysable factor obtained from sensitised T-cells by freezing and thawing, that may possibly immunopotentiate animals.The transfer of specific immunity from one animal to another has been claimed. (18 Nov 1997) |
| transfer genes | Gene's carried by a conjugative plasmid, essential for fertility and establishment of the bacterial donor state. (05 Mar 2000) |
| transfer imaging | The production of an ultrasound image by detection and analysis of sound on the opposite side of the body from the emitting transducer. Synonym: through transfer imaging. (05 Mar 2000) |
| transfer (psychology) | Change in learning in one situation due to prior learning in another situation. The transfer can be positive (with second learning improved by first) or negative (where the reverse holds). (12 Dec 1998) |
| energy transfer | The transfer of energy of a given form among different scales of motion. In biochemistry, this concept generally refers to the transfer of groups from compounds that contain energy-rich bonding arrangements to compounds that have relatively energy-poor bonding characteristics via thermodynamically permissible enzymatic reactions. This principle is a major premise of the interaction between energy-producing and energy-utilizing metabolic pathways in living cells. (12 Dec 1998) |
| zygote intra-fallopian transfer | <gynaecology> In vitro fertilization with a transfer of the zygote into the fallopian tube, a combination of in vitro fertilization and gamete intra-fallopian transfer. An assisted reproduction technique consisting of hormonal stimulation of the ovaries, laparoscopic follicular aspiration of oocytes, in-vitro fertilization, and intra-fallopian transfer of the zygote by transabdominal cannulation at the pronuclear stage (before cleavage). Acronym: ZIFT (12 Dec 1998) |
| fluorescence energy transfer | <technique> Transfer of energy from one fluorochrome to another. The emission wavelength of the fluorochrome excited by the incident light must approximately match the excitation wavelength of the second fluorochrome. If light at the second emission wavelength is detected, it implies that the two fluorochromes were physically within a few nanometres. Used as a technique to probe protein or cell interactions. (25 Jun 1999) |
| Fourier transfer | A mathematical technique to express a time-varying function or signal into components at different frequencies, giving the phase and amplitude of each; used in computed tomography and magnetic resonance image reconstruction transformation. (05 Mar 2000) |
| linear energy transfer | <radiobiology> Average amount of energy lost per unit of particle track length and expressed in keV um-1. Acronym: LET (16 Dec 1997) |
