Abstract
Blood oxygen saturation (SaO2) is one of the most important environmental factors in clinical heart protection. This study used human heart samples and human induced pluripotent stem cell-cardiomyocytes (iPSC-CMs) to assess how SaO2 affects human CM cell cycle activities. The results showed that there were significantly more cell cycle markers in the moderate hypoxia group (SaO2: 75% to 85%) than in the other 2 groups (SaO2 <75% or >85%). In iPSC-CMs 15% and 10% oxygen (O2) treatment increased cell cycle markers, whereas 5% and rapid change of O2 decreased the markers. Moderate hypoxia is beneficial to the cell cycle activities of post-natal human CMs.

Abstract
There are significant challenges involved in the perinatal and postnatal care of an infant with hypoplastic left heart syndrome (HLHS) and the infant's family. In the blink of an eye, the perfect child is lost, and a fragile infant is about to join the family. This case study and discussion is an overview of HLHS , a family's desire to make the birth of their infant normal, and how that desire initiated a change in philosophy and practice in our neonatal intensive care unit.

Abstract
Heart failure is an important cause of morbidity and mortality in individuals of all ages. The many-faceted nature of the clinical heart failure syndrome has historically frustrated attempts to develop an overarching explanative theory. However, much useful information has been gained by basic and clinical investigation, even though a comprehensive understanding of heart failure has been elusive. Heart failure is a growing problem, in both adult and pediatric populations, for which standard medical therapy, as of 2010, can have positive effects, but these are usually limited and progressively diminish with time in most patients. If we want curative or near-curative therapy that will return patients to a normal state of health at a feasible cost, much better diagnostic and therapeutic technologies need to be developed. This review addresses the vexing group of heart failure etiologies that include cardiomyopathies and other ventricular dysfunctions of various types, for which current therapy is only modestly effective. Although there are many unique aspects to heart failure in patients with pediatric and congenital heart disease, many of the innovative approaches that are being developed for the care of adults with heart failure will be applicable to heart failure in childhood.
