| 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) |

Elaborate wall ingrowths greatly increase the area of plasma membrane at the cell face across which transfer occurs. (17 Mar 1998) |

| 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 RNA | <molecular biology> A nucleic acid found in all living cells. Plays a role in transferring information from DNA to the protein-forming system of the cell. (16 Dec 1997) |
| transferase | <enzyme> A suffix to the name of an enzyme indicating that it transfers a specific grouping from one molecule to another, for example acyl transferases transfer acyl groups. (18 Nov 1997) |
| transferase deficiency galactosaemia | An autosomal recessive disorder in which there is a deficiency of galactose-1-phosphate uridylyltransferase (see main entry for galactosaemia). (05 Mar 2000) |
| transferases | <enzyme> Transferases are enzymes transferring a group, for example, the methyl group or a glycosyl group, from one compound (generally regarded as donor) to another compound (generally regarded as acceptor). The classification is based on the scheme "donor:acceptor group transferase". Registry number: EC 2. (12 Dec 1998) |
| transferases (other substituted phosphate groups) | <enzyme> A class of enzymes that transfers substituted phosphate groups. Registry number: EC 2.7.8 (12 Dec 1998) |
| transference | <psychology> The unconscious transfer to others (including psychotherapists) of feelings and attitudes which were originally associated with important figures (parents, siblings, etc.) in one's early life. (12 Dec 1998) |
| transference love | Love expressed by the patient for the psychoanalyst as a manifestation of transference. (05 Mar 2000) |
| adoptive transfer | Form of passive immunization where previously sensitised immunologic agents (cells or serum) are transferred to non-immune recipients. When transfer of cells is used as a therapy for the treatment of neoplasms, it is called adoptive immunotherapy (immunotherapy, adoptive). (12 Dec 1998) |

| gamete intra-fallopian transfer | <gynaecology> Gamete intra-fallopian transfer is a technique that involves combining eggs and sperm outside of the body and immediately placing them into the fallopian tubes to achieve fertilization. A technique that came into use in the mid-1980's for assisted conception in infertile women with normal fallopian tubes. The protocol consists of hormonal stimulation of the ovaries, followed by laparoscopic follicular aspiration of oocytes, and then the transfer of sperm and oocytes by catheterization into the fallopian tubes. Acronym: GIFT (12 Dec 1998) |
| gel transfer | Any lab technique used to transfer substances which had been separated using gel electrophoresis from the gel to a membrane for further processing or analysis. For example: any type of blotting. (09 Oct 1997) |
| gene transfer | <molecular biology> General tem for the insertion of foreign genes into a cell or organism. Synonymous with transfection. (18 Nov 1997) |
| cavernous transfer of portal vein | <anatomy, vein> Replacement of the portal vein by a number of collateral channels, a consequence of thrombosis. (05 Mar 2000) |
| patient transfer | Interfacility or intrahospital transfer of patients. Intrahospital transfer is usually to obtain a specific kind of care and interfacility transfer is usually for economic reasons as well as type of care provided. (12 Dec 1998) |
| resistance-transfer factor | The transfer gene of the resistance plasmid. (05 Mar 2000) |
| resonance 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) |
| charge transfer | A complex between two organic molecules in which an electron from one (the donor) is transferred to the other (the acceptor), becoming generally distributed throughout the latter; subsequent transfer of a hydrogen atom completes the reduction of the acceptor; such complex's are generally highly coloured and may be so observed, a network of hydrogen bridges at the catalytic centre of certain proteases. Synonym: charge transfer system. (05 Mar 2000) |
| charge transfer complex | A complex between two organic molecules in which an electron from one (the donor) is transferred to the other (the acceptor), becoming generally distributed throughout the latter; subsequent transfer of a hydrogen atom completes the reduction of the acceptor; such complex's are generally highly coloured and may be so observed, a network of hydrogen bridges at the catalytic centre of certain proteases. Synonym: charge transfer system. (05 Mar 2000) |

| group transfer | The transfer of a functional moiety from one molecule to another. (05 Mar 2000) |
| RNA, transfer | In cooperation with the ribosomes, transfer RNA brings (transfers) activated amino acids into position along the messenger RNA template. The abbreviation for transfer RNA is trna. (12 Dec 1998) |
| RNA, transfer, ala | A transfer RNA which is specific for carrying alanine to sites on the ribosomes in preparation for protein synthesis. (12 Dec 1998) |
| RNA, transfer, amino acid-specific | A group of transfer rnas which are specific for carrying each one of the 20 amino acids to the ribosome in preparation for protein synthesis. (12 Dec 1998) |
