The endogenous circadian clock drives oscillations that are completely synchronized with the environmental day-night rhythms with a period of approximately 24 hours. Temporal misalignment between one's internal circadian clock and the external solar time often occurs in shift workers and long-distance travelers; such misalignments are accompanied by sleep disturbances and gastrointestinal distr...
Jet lag, circadian rhythm sleep disturbances, and depression: the role of melatonin and its analogs.
Traveling through several time zones results in a constellation of symptoms known as jet lag. These include reduced alertness, daytime fatigue, loss of appetite, reduced cognitive skills, and disruption of the sleep/wake cycle. In susceptible air travel passengers, jet lag may exacerbate affective illness and result in psychiatric morbidity. Dysregulation of circadian rhythms and melatonin secr...
Circadian rhythm has been linked to cancer genesis and development, but the detailed mechanism by which circadian disruption accelerates tumor growth remains unclear. The purpose of this study was to investigate the effect of circadian disruption on tumor growth and metastasis in male C57BL/6 mice, using an experimental chronic jet lag model. Lewi...
Peak Luminosity-Spectral Lag Relation Caused by the Viewing Angle of the Collimated Gamma-Ray Bursts
We compute the kinematical dependence of the peak luminosity, the pulse width and the spectral lag of the peak luminosity on the viewing angle θv of a jet. For appropriate model parameters we obtain the peak luminosity-spectral lag relation similar to the observed one including GRB980425. A bright (dim) peak with short (long) spectral lag corresponds to a jet with small (large) viewing angle. T...
Travel across multiple time zones is a common feature of modern life. After transmeridian flights, the internal clocks are desynchronized from the external environment and it can take several days to readjust to the new external time cues. The time taken is related to the direction of the flight and to the number of time zones crossed as well as to individual variability. The result of this des...
