This paper presents a new methodology, based on the probabilistic approach, for biorhythmic analysis to prevent aviation accidents. The methodology has been developed using the Gaussian distribution technique for reliability evaluation of the aviation system, keeping in mind the biorhythmic effects of the pilot. The normal distributed data of the US Air Force were tested and analysed based on t...

Aging is known to disrupt the "biological clock" that governs physiological variables at rest. This study sought to determine whether aged men demonstrated biorhythmic variation in muscle performance during resistance exercise and physiological responses to that stimulus. Ten aged (75.6 +/- 1.6 yr; mean +/- SE) men completed an isokinetic testing protocol of knee extensors and flexors at 0800, ...

Chronobiological markers of depression display a biological desynchronization which participates in the pathogenesis of depression. Mood disorders and clock genes have shown significant associations suggesting a possible pathogenetic link between them, providing a privileged base for exploring biorhythmic endophenotypes. They would be useful indicators of vulnerability mechanisms, giving rise t...

The physiological function of intracellular calcium oscillations has eluded investigators. Given that calcium plays an important role in many signal transduction processes and that the frequency of oscillations can be controlled by external agonists, the biorhythmic phenomena may represent a type of frequencyencoded information train. In this thesis, I propose that calcium-activated, enzyme sys...
