Operation of a homeostatic sleep switch [PDF]
Nature, 2016 Sleep disconnects animals from the external world, at considerable risks and costs that must be offset by a vital benefit. Insight into this mysterious benefit will come from understanding sleep homeostasis: to monitor sleep need, an internal bookkeeper must track physiological changes that are linked to the core function of sleep.

Morbidity of the Arterial Switch Operation [PDF]
The Annals of Thoracic Surgery, 2012 The arterial switch operation (ASO) has become a safe, reproducible surgical procedure with low mortality in experienced centers. We examined morbidity, which remains significant, particularly for complex ASO.From 2003 to 2011, 101 consecutive patients underwent ASO, arbitrarily classified as "simple" (n=52) or "complex" (n=49).

Arterial Switch Operation: Operative Approach and Outcomes [PDF]
The Annals of Thoracic Surgery, 2019 The arterial switch operation has excellent early outcomes. Although the majority of patients are growing into healthy adults, a small subset require reoperation for pulmonary stenosis as well as neoaortic root dilatation and neoaortic valve regurgitation, especially as follow-up increases. Challenging subgroups include patients with anomalous coronary
