| delayed reaction experiment | A method of measuring memory: a stimulus is presented and removed before the organism is permitted to respond to it; the interval during which the stimulus is absent, providing the organism responds correctly, is an indication of the length of memory. (05 Mar 2000) |

| delayed rectifier channel | <physiology> The potassium selective ion channels of axons, so called because they change the potassium conductance with a delay after a voltage step. The name is used to denote any axon like K channel. Various roles for example regulation of pacemaker potentials, generation of bursts of action potentials or generation of long plateaus on action potentials. (18 Nov 1997) |
| delayed reflex | A reflex in which a little time elapses between stimulus and response. See: trace conditioned reflex. (05 Mar 2000) |
| delayed sensation | A sensation that is not perceived until the lapse of an appreciable interval following the application of the stimulus. General sensation, a sensation referred to the body as a whole rather than to any particular part. (05 Mar 2000) |
| delayed suture | A suturing of a wound after an interval of days. (05 Mar 2000) |
| delayed type hypersensitivity | <immunology> Hypersensitivity (increased reaction by the body to a foreign substance such as an antigen or allergen) that does not appear until 24 to 48 hours after the body is exposed to the foreign substance. (09 Oct 1997) |
| ovum implantation, delayed | Delay of embryonal development whereby the blastocyst remains in the uterine cavity for a variable period of time before attaching to the endometrium and continuing its development. (12 Dec 1998) |
| 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.
