Impaired modulation of circadian rhythms in patients with diabetes mellitus: a risk factor for cardiac thrombotic events?

abstract：:Although there are significant intra-individual differences in self-reported diurnal preference, as measured by validated questionnaires, the relative contribution of exogenous and endogenous factors to self-reported diurnal preference largely remains to be investigated. The present study examined which items from the...

abstract：:The circadian system is organized in a hierarchy of multiple oscillators, with the suprachiasmatic nucleus (SCN) as the master oscillator in mammals. The SCN is formed by a group of coupled cell oscillators. Knowledge of this coupling mechanism is essential to understanding entrainment and the expression of circadian ...
