The circadian rhythms of most shiftworkers do not adapt to night shift. We have studied oil workers on a rotating system involving 2 weeks day shift (0600-1800 h) and 2 weeks night shift (1800-0600 h) throughout a day and night shift sequence. Urine samples were collected 3-hourly whilst awake, with an over-sleep collection, for the measurement of(More)
Previously we have shown that the 6-sulphatoxymelatonin rhythm of oil rig workers on a 2-week night shift (1800-0600 h) adapts to the shift via a phase delay. We now report the findings of a study on two offshore drill crews working a 1 week day (1200-0000 h), 1 week night (0000-1200 h) swing shift. Urine samples were collected every 2-3 h throughout the(More)
The coordinated regulation of mitochondrial and nuclear activities is essential for cellular respiration and its disruption leads to mitochondrial dysfunction, a hallmark of ageing. Mitochondria communicate with nuclei through retrograde signalling pathways that modulate nuclear gene expression to maintain mitochondrial homeostasis. The monooxygenase CLK-1(More)
Evaluation events are major problems for graduate students in nursing. The purpose of this study was to determine the correlation of test anxiety before and cognitive interferences during a comprehensive examination. The sample (N = 54) consisted of two groups of students (Group I, N = 30 and Group II, N = 24) in a master's program at a state university.(More)
The temperature dependence of the nuclear spin-lattice relaxation rate R\ of Sc has been measured in scandium dihydrides and dideuterides. These data are satisfactorily accounted for by two contributions to /?,, R]e due to conduction electrons, and R]Q due to quadrupo le interaction fluctuations resulting f rom vacancy diffusion on the hydrogen (deuter ium)(More)
