Smoking
Definition:
(p. pr. & vb n.) of Smoke
() a. & n. from Smoke.
Example Sentences:

(7) Plasma renin activity (PRA) and aldosterone concentration were measured before and during submaximal exercise in 10 male monozygotic twin pairs who were discordant for smoking.
(8) The results indicated that smoke, as opposed to sham puffs, significantly reduced reports of cigarette craving, and local anesthesia significantly blocked this immediate reduction in craving produced by smoke inhalation.
(9) This study examines the extent to which changes in smoking can account for the decrease in CHD mortality for men and women aged 35-64 years.
(10) However, as all subjects had normal hearing and maximum speech discrimination scores pre-smoking, it can only be concluded that smoking marihuana did not worsen the hearing--the experiments were not designed to see whether it would improve hearing.
(11) Further analysis of these changes according to smoking history, age, preoperative weight, dissection of IMA, and aortic cross-clamp time showed that only IMA dissection affected the postextubation changes in peak expiratory flow rate (p less than 0.0001), whereas the decreases in functional residual capacity and expiratory reserve volume at discharge were affected by IMA dissection (p less than 0.05) and age (p = 0.01).
