Intolerance to shift work may result from individual susceptibility to an internal desynchronization. Some shift workers (SW) who show desynchronization of their circadian rhythms (e.g., sleep-wake, body temperature, and grip strength of both hands) exhibit symptoms of SW intolerance, such as sleep alteration, persistent fatigue, sleep medication(More)
The study was designed to test the hypothesis that the prominent rhythm period tau of simple reaction time (SRT) and three-choice reaction time (CRT) to light signals may vary between the dominant (DH) and non-dominant (NDH) hand. Eleven healthy subjects, 8 males (16-74 years, including two left-handed) and 3 females (18-43 years), synchronized with a(More)
The authors define a subject as euchronic when the circadian parameters--tau (tau=period), Ø (acrophse or peak time), A (amplitude), and M (MESOR=24 h rhythm-adjusted mean)--of a set of circadian variables are within the confidence limits of appropriate reference values of healthy subjects (HS). We define internal desynchronization as a state in which the(More)
In healthy mature subjects simple reaction time (SRT) to a single light signal (an easy task) is associated with a prominent rhythm with tau = 24 h of dominant (DH) as well as nondominant (NDH) hand performance, while three-choice reaction time (CRT), a complex task, is associated with tau = 24 h of the DH but tau < 24 h of the NDH.

The aim of the study was to explore circadian alterations of the temperature rhythm in adults with Major Affective Disorders (DSM III-R:296.xx). The axillary temperature of 56 inpatients was recorded (6-min intervals for at least a 48-h span) when major clinical symptoms occurred and thereafter during the remission. Periods (tau s) of the temperature rhythm(More)
Biological rhythms and their temporal organization are adaptive phenomena to periodic changes in environmental factors linked to the earth's rotation on its axis and around the sun. Experimental data from the plant and animal kingdoms have led to many models and concepts related to biological clocks that help describe and understand the mechanisms of these(More)
596 Background: Association between osteonecrosis of the jaw (ONJ) and bisphosphonate treatment has been increasingly reported in the literature. METHODS This is a retrospective review of a single institution's experience with patients diagnosed with bone metastasis secondary to breast cancer, who developed ONJ while treated with bisphosphonates(More)
The purpose of the present study was to assess the temporal variation of the facial electroneurography (ENoG) parameters recorded from the nasolabial crease and to compare it to the temporal oscillations of oral and facial cutaneous temperatures. Twelve healthy individuals were examined at 4-hour intervals for 2 consecutive days. Twenty-four-hour rhythms of(More)
