Photorefractoriness and its termination in the subtropical house sparrow, Passer domesticus: involvement of circadian rhythm.

abstract：:Disruption of circadian rhythms, which frequently occurs during night shift work, may be associated with cancer progression. The effect of chronotype (preference for behaviors such as sleep, work, or exercise to occur at particular times of day, with an associated difference in circadian physiology) and alignment of b...
