() a. & n. from Sleep.
Example Sentences:

(6) This was carried out on the healthy subjects for a total of 12 nights without medication (control nights asleep), a total of 12 nights following 40 mg of flucortolone the previous morning, and a total of 6 nights with similar blood sampling when sleep was prevented (control nights awake).
(7) Although temazepam was effective for maintaining sleep with short-term use, there was rapid development of tolerance for this effect with intermediate-term use.
(8) The occurrence of episodes of desaturation during sleep in patients suffering from chronic airflow obstruction is well known.
(9) A lower than normal percentage of REM sleep in these patients was consistent with their retarded intellectual development, which supports current thinking that REM sleep may be a sensitive index of brain function integrity.
(10) Amine metabolites, 5-hydroxyindoleacetic acid (5HIAA), and homovanillic acid (HVA) were not substantially affected by sleep deprivation, although there was a significant interaction of clinical response and direction of 3-methoxy-4-hydroxyphenylglycol (MHPG) change.
