Human Heart Rhythms Synchronize While Co-sleeping

Sleeping while driving.

Circadian rhythms synchronize mitosis in Neurospora crassa.

The cell cycle and the circadian clock communicate with each other, resulting in circadian-gated cell division cycles. Alterations in this network may lead to diseases such as cancer. Therefore, it is critical to identify molecular components that connect these two oscillators. However, molecular mechanisms between the clock and the cell cycle remain largely unknown. A model filamentous fungus,...

It Happened While You Were Sleeping

P redicting shortand long-term risk for adverse outcomes after an acute coronary syndrome (ACS; STsegment elevation myocardial infarction, non–ST-segment elevation myocardial infarction, and unstable angina) has been the focus of numerous modeling efforts over many years. Nevertheless, risk models can reflect only the variables that were systematically available in the population databases used...

Putting co-sleeping into perspective.

Co-sleepingbegins in infancy andoften continues through to childhood as part of early nurturing practices. In evolutionary terms the human infant is the most neurologically immature primate at birth and develops the most slowly, thus intense and prolonged mother-infant contact acts as a protectivemechanismagainst physiological difficulties and environmental assaults. Proposed benefits of close ...

The Sleeping Heart : Hibernating Myocardium

Classical teaching about myocardial ischemia is now being challenged by exciting new concepts that have been evolving over the past two decades. It is now recognized that prolonged myocardial ischemia does not inevitably lead to irreversible necrosis of myocardial tissue. Similarly, segment dysfunction in the ventricle does not necessarily imply that the myocardium in that area has undergone in...
