| signal transduction | The cascade of processes by which an extracellular signal (typically a hormone or neurotransmitter) interacts with a receptor at the cell surface, causing a change in the level of a second messenger for example calcium or cyclic AMP) and ultimately effects a change in the cells functioning (for example: triggering glucose uptake or initiating cell division). Can also be applied to sensory signal transduction, for example of light at photoreceptors. (18 Nov 1997) |

| signal void | In magnetic resonance imaging, a region emitting no radiofrequency signal, either because there are no activated protons in the region (such as flowing blood) or because a different element predominates, particularly calcium. (05 Mar 2000) |
| nuclear localization signal | Short, predominantly basic amino acid sequences identified as nuclear import signals for some proteins. These sequences are believed to interact with specific receptors at nuclear pores. (12 Dec 1998) |
| anti-anxiety agents | Agents that alleviate anxiety, tension, and neurotic symptoms, promote sedation, and have a calming effect without affecting clarity of consciousness or neurologic conditions. Some are also effective as anticonvulsants, muscle relaxants, or anaesthesia adjuvants. Adrenergic beta-antagonists are commonly used in the symptomatic treatment of anxiety but are not included here. Substances with a benzodiazepine ring structure widely used to treat anxiety and neuroses. Drugs in this class also generally have sedative or weak hypnotic properties and may be effective as muscle relaxants, anticonvulsants, and anaesthesia adjuvants. (12 Dec 1998) |
| anxiety | <psychology> The unpleasant emotional state consisting of psychophysiological responses to anticipation of unreal or imagined danger, ostensibly resulting from unrecognised intrapsychic conflict. Physiological concomitants include increased heart rate, altered respiration rate, sweating, trembling, weakness and fatigue, psychological concomitants include feelings of impending danger, powerlessness, apprehension and tension.

| anxiety disorders | Disorders in which anxiety (persistent feelings of apprehension, tension, or uneasiness) is the predominant disturbance. (12 Dec 1998) |
| anxiety dream | A dream (or nightmare) in which morbid fear and anxiety form an important part. (05 Mar 2000) |
| anxiety hysteria | Hysteria characterised by manifest anxiety. (05 Mar 2000) |
| anxiety neurosis | Chronic abnormal distress and worry to the point of panic followed by a tendency to avoid or run from the feared situation, associated with overaction of the sympathetic nervous system. (05 Mar 2000) |
| anxiety reaction | A sudden bout of anxiety that is often accompanied by the features of hyperventilation (tingling around mouth and in fingertips, rapid breathing, faintness or fainting). (27 Sep 1997) |
| anxiety, separation | Anxiety experienced by an individual upon separation from a person or object of particular significance to him. (12 Dec 1998) |
