| ALL | <haematology> A rapidly progressing cancer of the blood affecting the type of white blood cell known as lymphocytes. Approximately 650 new cases are diagnosed every year in the UK and it is the most common form of childhood leukaemia. Acronym: ALL Origin: Gr. Haima = blood (11 Nov 1997) |
| all-or-nothing phenomenon | <physiology> Refers to the phenomenon where the strength of a nerve impulse is not dependent on the strength of the stimulus. Instead, there is a threshold level of stimulus strength that must be reached before the nerve will fire an impulse (at full capacity). Below the threshold, the nerve will not fire at all. <cardiology> It also refers to the same phenomenon observed in the heart muscle, which will either contract fully or not at all. <psychology> In studies of behaviour, it refers to the same phenomenon where a behavioural stimulus will either produce a complete response or no response at all. Also called all-or-nothing principle, all-or-none law, all-or-none responsiveness, etc. (15 Nov 1997) |
| all souls' day | The second day of November; a feast day of the Roman Catholic church, on which supplications are made for the souls of the faithful dead. Source: Websters Dictionary (01 Mar 1998) |
| all-trans-retinal | The orange retinaldehyde resulting from the action of light on the rhodopsin of the retina, which converts the 11-cis-retinal component of the rhodopsin to all-trans-retinal plus opsin. Synonym: trans-retinal, visual yellow. (05 Mar 2000) |
| stains-all | 4,5,4',5'-Dibenzo-3,3'-diethyl-9-methylthiocarbocyanine bromide;a dye that stains phosphoproteins blue, proteins red, nucleic acids purple, and mucoproteins and mucopolysaccharides various colours on acrylamide gels; also used on tissue sections. (05 Mar 2000) |
| anamnestic response | <immunology> Archaic term now replaced by such terms as secondary immune response, immune memory. (18 Nov 1997) |
| audiometry, evoked response | A form of electrophysiologic audiometry in which an analog computer is included in the circuit to average out ongoing or spontaneous brain wave activity. A characteristic pattern of response to a sound stimulus may then become evident. Evoked response audiometry is known also as electric response audiometry. (12 Dec 1998) |
| auditory brainstem response audiometry | An electrophysiologic measure of auditory function utilizing responses produced by the auditory nerve and the brainstem to repetitive acoustic stimuli. (05 Mar 2000) |
| biological response modifier | <pharmacology, oncology> A substance used in adjuvant therapy that takes advantage of the bodys own natural defense mechanisms to inhibit the growth of a tumour. (16 Dec 1997) |
| biological response modifiers | Substances that stimulate the body's response to infection and disease. The body naturally produces small amounts of these substances. Scientists can produce some of them in the laboratory in large amounts and use them in cancer treatment. Also called BRMs. (12 Dec 1998) |
| biphasic response | Two separate and distinct responses that are separated in time, immediate reaction to an antigenic challenge followed by a recurrence of symptoms after an interval of quiescence. (05 Mar 2000) |
