Sexual selection favours the expression of traits in one sex that attract members of the opposite sex for mating. The nature of sexually selected traits such as vocalization, colour and ornamentation, their fitness benefits as well as their costs have received ample attention in field and laboratory studies. However, sexually selected traits may not always be expressed: coloration and ornaments...

Brunetto Tarquini, head of Internal Medicine at the University of Florence, Italy, died at the peak of a productive career. A few days before his passing, his contributions to the 6th National Congress of the Italian Society for Chronobiology in Chianciano Terme—in the footsteps of the Roman poet Horace and the emperor Augustus (Rastrelli 1999; Soren and Romer 1999)—exuded scholarship, which we...

BACKGROUND Chronobiology studies the recurrent biologic rhythms that directly affect how an organism interacts with its environment and how its environment affects the organism. The purpose of this study is to determine whether the time of administration influences the analgesic duration of the commonly used subarachnoid fentanyl for labor analgesia. METHODS After institutional review board a...

Aging is generally associated with weakening of the circadian system. The circadian amplitude is reduced and the circadian acrophase becomes more labile, tending to occur earlier with advancing age. As originally noted by Franz Halberg, similar features are observed in the experimental laboratory after bilateral lesioning of the suprachiasmatic nuclei, suggesting the involvement of clock genes ...
