A peek into the interplay between sleep and wakefulness
The ventrolateral preoptic nucleus (VLPO) in the brain plays a critical role in the initiation and maintenance of sleep, while the lateral posterior part of the hypothalamus contains neuronal populations implicated in maintenance of arousal.
Speed up solving complex problems: Be lazy and only work crucial tasks
A new improvement to a programming technique called 'lazy grounding' could solve hard-set and complex issues in freight logistics, routing and power grids by drastically reducing computation times.
Supplemental oxygen eliminates morning blood pressure rise in sleep apnea patients
Supplemental oxygen eliminates the rise in morning blood pressure experienced by obstructive sleep apnea (OSA) patients who stop using continuous positive airway pressure (CPAP), the standard treatment for OSA, according to new research published online in the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.
Frailty may be more deadly in younger heart patients, study finds
A new study conducted by researchers at the University of Ottawa Heart Institute and published in the Journal of the American Heart Association examines the prevalence of frailty and its association with long-term mortality in patients undergoing cardiac surgery.
A molecular key for delaying the progression of Multiple Sclerosis is found
In the lab it was possible to improve the symptoms in the chronic phase of the disease while encouraging the repair of the nervous tissue, and the challenge now is to move the research forward in humans.
