Abstract Introduction Sleep restriction is associated with impairments to cognitive performance. A current strategy improve performance at work breaking up prolonged sitting light-intensity walking. However, it unknown whether this can counteract the impact of sleep restriction. This study investigated effect on under conditions Method 84 healthy adults (age M± SD 23.1±4.5 years; 41 females) pa...

Three patients admitted to the intensive care unit after multiple injury were observed to suffer episodes of adrenocortical insufficiency suggested by clinical manifestations and confirmed by appropriately low cortisol concentrations. This prompted a prospective study of pituitary-adrenocortical function in six multiply injured patients, three of whom showed evidence of adrenocortical suppressi...

BACKGROUND This work describes the effect of a 48-h litter separation on 24-h patterns of plasma prolactin, FSH and LH concentration in female lactating rabbits kept under a 16:8 light-dark photoperiod (lights on at 0800 h). METHODS Groups of 6-7 female lactating rabbits maintained with their litters or separated from them for 48 h were killed by decapitation on day 11 post-partum, at 6 diffe...

We investigated the effects of a 5-h sleep restriction for 7 d on subjective sleepiness in an ambulatory condition by comparing them with baseline conditions consisting of an 8-h sleep for 7 consecutive days. Subjects were 13 healthy male students (mean age 21.1 yr). Each subject was required to get 8 h of sleep (baseline, from 2300 to 0700) for 7 d, and 5 h of sleep (sleep restriction, from 01...

A system has been established for continuous recording of rectal and body surface temperatures in conscious, chair-restrained rhesus macaques. Diurnal changes in rectal temperature and body surface temperatures of head, back, abdomen, and inner thigh were recorded for 24 hours under conditions of intermittent or constant light. When lights were on for 8 hours (0800 to 1600 hours) and off for 16...

Field investigations were conducted to determine the resting locations of codling moth (Cydia pomonella [L.]) (Lepidoptera: Tortricidae) males and females in mating disrupted and nondisrupted apple (Malus domestica Borkh.) orchard plots. A custom-made sampling device, consisting of a leaf blower converted into a powerful vacuum, yielded 20-24% success in recovering marked moths, released in th...
