REVIEW
D Grahame Hardie
Living cells obtain energy either by oxidizing reduced compounds of organic or mineral origin or by absorbing light. Whichever energy source is used, some of the energy released is conserved by converting adenosine diphosphate (ADP) to adenosine triphosphate (ATP), which are analogous to the chemicals in a rechargeable battery. The energy released by the conversion of ATP back to ADP is used to drive most energy-requiring processes, including cell growth, cell division, communication and movement. It is clearly essential to life that the production and consumption of ATP are always maintained in balance, and the AMP-activated protein kinase (AMPK) is one of the key cellular regulatory systems that ensures this...

Use of vent-free gas heating appliances for supplemental heating in U.S. homes is increasing. However, there is currently a lack of information on the potential impact of these appliances on indoor air quality for homes constructed according to energy-efficient and green building standards. A probabilistic analysis was conducted to estimate the impact of vent-free gas heating appliances on indoor air concentrations of carbon monoxide (CO), nitrogen dioxide (NO2), carbon dioxide (CO2), water vapor, and oxygen in "tight" energy-efficient homes in the U...

There is a dearth of information regarding the functional abilities of patients with the total artificial heart (TAH). Increased utilization of the TAH and patient discharge to home with the portable unit necessitates a shift in focus to quality of life, which includes quantifying and ultimately optimizing functional capacity. To date, only single-patient case studies have described the exercise response of the TAH patient. Fourteen patients with the TAH underwent cardiopulmonary exercise testing with concurrent analysis of TAH device function...

We describe the use of extracorporeal cardiopulmonary resuscitation (E-CPR) to transiently stabilize a 3-month-old patient who presented with ventricular tachyarrhythmias leading to spontaneous cardiac arrest. The patient required 4 days of extracorporeal life support (ECLS) where he was diagnosed with probable Brugada syndrome (BS). The patient was discharged home in stable condition after implantable cardioverter defibrillator placement. This case highlights the importance of early transfer to extracorporeal membrane oxygenation (ECMO) center in the setting of unexplained cardiac arrhythmia in a pediatric patient...

A range of devices are available for delivering and monitoring home oxygen therapy (HOT). Guidelines do not give indications for the choice of the delivery device but recommend the use of an ambulatory system in subjects on HOT whilst walking. Areas covered: We provide a clinical overview of HOT and review traditional and newer delivery and monitoring devices for HOT. Despite relevant technology advancements, clinicians, faced with many challenges when they prescribe oxygen therapy, often remain familiar to traditional devices and continuous flow delivery of oxygen...

OBJECTIVES: High fractions of inspired oxygen may augment lung damage to exacerbate lung injury in patients with acute respiratory distress syndrome. Participants enrolled in Acute Respiratory Distress Syndrome Network trials had a goal partial pressure of oxygen in arterial blood range of 55-80 mm Hg, yet the effect of oxygen exposure above this arterial oxygen tension range on clinical outcomes is unknown. We sought to determine if oxygen exposure that resulted in a partial pressure of oxygen in arterial blood above goal (> 80 mm Hg) was associated with worse outcomes in patients with acute respiratory distress syndrome...

OBJECTIVE: Cardiopulmonary bypass (CPB) and deep hypothermic circulatory arrest (DHCA) are commonly used in cardiac surgery. However, the mortality and morbidity are still high in practice. Developing novel protective stategies and elucidating the underlying mechanisms for the pathophysiological consequences of DHCA have been hampered because of the absence of a satisfactory recovery animal model. The aim of this study was to establish a novel and safe DHCA model without blood priming in rats to study the pathophysiology of potential complications...

Generally, infective endocarditis is found at the left side of the heart. The right side infective endocaritis accounts for only 5~10% of all cases of infective endocarditis. The right side infective endocarditis occurs especially among drug users employing intravenous injection. A typical site of infection is the tricupid valve, and isolated pulmonary valve involvement is rare. It is assumed that its rarity is due to the low pressure gradients within the right heart, the low prevalence of valve disease, and the lower oxygen content of the venous blood...

The development of highly active and stable oxygen evolution reaction (OER) electrocatalysts is crucial for improving the efficiency of water splitting and metal-air battery devices. Herein, an efficient strategy is demonstrated for making the oxygen vacancies dominated cobalt-nickel sulfide interface porous nanowires (NiS2 /CoS2 -O NWs) for boosting OER catalysis through in situ electrochemical reaction of NiS2 /CoS2 interface NWs. Because of the abundant oxygen vacancies and interface porous nanowires structure, they can catalyze the OER efficiently with a low overpotential of 235 mV at j = 10 mA cm-2 and remarkable long-term stability in 1...

We evaluated the feasibility, tolerability, and efficacy of a strategy for transaxillary artery intra-aortic balloon pump placement for extended mechanical circulatory support of patients with postcardiotomy shock as a bridge to recovery. Patients requiring prolonged intra-aortic balloon pump support for postcardiotomy heart failure were identified. Intra-aortic balloon pump was tunneled through a 6-mm Dacron graft anastomosed to the right axillary artery. The intra-aortic balloon pump catheter is advanced under fluoroscopic guidance into the descending thoracic aorta...

This paper examines whether water quality has an effect on recreational boating activity. The analysis is based on survey data collected by face-to-face interviews with recreational visitors to 10 waterway sites across Ireland. We model the respondent's choice decision to travel to a specific site for the purposes of beginning their recreational boating activity. Water quality data is from European Union Water Framework Directive monitoring stations. Across recreational sites, which have generally high water quality levels within our sample, we find that boaters favour sites with better water quality; as indicated by biological oxygen demand and phosphates metrics...
