Nine permanent night shift workers were admitted to the Clinical Research Center (CRC) directly from their last work shift of the week and remained in dim light while blood samples were obtained hourly for 24 hours. Melatonin concentrations were measured in these samples using a gas-chromatographic...
For some time, it has remained uncertain whether the circadian rhythms of permanent night shift workers are adapted to their night-active schedule. Previous studies of this question have often been limited by "masking" (evoked) effects of sleep and activity on body temperature and cortisol, used...
Night shift work has been associated with higher breast cancer risk. It has been proposed that night shift workers experience light-induced reduction in melatonin production. Melatonin has direct oncostatic properties and a potential interplay with reproductive hormones. In this cross-sectional study ...
Adult body mass index (BMI) has been associated with urinary melatonin levels in humans; however, whether earlier-life body size is associated with melatonin, particularly among night shift workers, remains unknown. We evaluated associations of birth weight, body shape (or somatotype) at ages 5 ...

Melatonin as a chronobiotic : PROS and CONS 来自 Semantic Scholar 喜欢 0 阅读量: 4 作者: S. 摘要: The pineal gland is a major component in the regulation of photoperiodic responses and hence, saisonality. All functions which appear to be controlled by the daylength can be influenced by ...
The difficulties experienced by shiftworkers are multi-facetted and vary with the type of schedule, type of work (physical and mental workload), familial situation, age, health status, etc. Nevertheless, it has been consistently reported that sleep difficulties and fatigue are the main complaints...
Examines the circadian secretion patterns of cortisol and pineal hormone melatonin in permanent night shift workers with high degree of work satisfaction. Rhythm adjustments to nocturnal work schedule at the end of night shift; Indicators for the phase of circadian hormone rhythms; Amplitude of ...
