The aim of this study was to evaluate the influence of nicotine on the daily rhythms of heart rate, body temperature and locomotor activity in unrestrained rats by use of implanted radiotelemetry transmitters. The study was divided into three seven-day periods: a control period, a treatment period and a recovery period. The control period was used for(More)
The aim of this study was to evaluate the effect of anaesthesia (ether or ketamine) on daily rhythms of temperature (T), heart rate (H) and locomotor activity (A) in unrestrained rats by using implanted radio-telemetry transmitters. T, H and A were measured every 10 min, in Wistar male rats, and analysed using Cosinor. The mean +/- SEM days needed, after(More)
Even if the effects of caffeine on some physiological parameters are well known, its influence on circadian rhythmicity had not yet been investigated. This possible influence is of particular importance, introducing a possible bias in chronopharmacological studies. Thus, the aim of this study was to evaluate the effects of repeated caffeine administration(More)
The aim of this study was to compare morning and evening repeated nicotine administration on the circadian rhythms of heart rate (H), body temperature (T) and locomotor activity (A) in unrestrained rats by using implanted radio-telemetry transmitters. The study was divided into three 7-day periods: a control period (P1), a treatment period (P2) and a(More)
Using radiotelemetry, this study aimed to evaluate the influence of tobacco smoke on heart rate (H), body temperature (T) and locomotor activity (A) daily rhythms in rats. The tobacco smoke intoxication was produced with a smoking apparatus. H, T, and A data were captured by radiotelemetry. The study was divided into three periods: a 1-week control period(More)
What difficulties do children encounter when responding to complementation instructions? The responses of 50 children to six complementation requests were examined. For half of the children, the objects in the referential set were pooled, and for the other half, they were physically separated by category (pencils were presented in a pencil box, buttons in a(More)
