Biological Rhythms and Preeclampsia

The impact of impaired circadian rhythm on health has been widely studied in shift workers and trans-meridian travelers. A part from its correlation with sleep and mood disorders, biological rhythm impairment is a recognized risk factor for cardiovascular diseases and breast cancer. Preeclampsia is a major public health issue, associated with a significant maternal and fetal morbidity and morta...

Mammalian Seasonal Rhythms: Behavior and Neuroendocrine Substrates

“Environmental seasonality. . . a basic component of the ecosystem within which our ancestors evolved. . . left its mark indelibly upon the makeup of our biology and our behaviour.” ( Johnston, 1993) “the ability to perceive changes in daylength indicated by changes in the duration of melatonin secretion. . . is the only essential function attributable to melatonin in mammals to date.” (Arendt,...

MP Systems Approaches to Biochemical Dynamics: Biological Rhythms and Oscillations

Metabolic P systems are a special class of P systems which seem to be adequate for expressing biological phenomena related to metabolism and signaling transduction in biological systems. We give the basic motivation for their introduction and some ideas about their applicability to some basic biological oscillators.

Biological rhythms and vector insects

The adjustment of all species, animals and plants, to the Earth's cyclic environments is ensured by their temporal organisation. The relationships between parasites, vectors and hosts rely greatly upon the synchronisation of their biological rhythms, especially circadian rhythms. In this short note, parasitic infections by Protozoa and by microfilariae have been chosen as examples of the depend...
