OPINION STATEMENT There are more than 300,000 out-of-hospital cardiac arrests (OHCA) in the USA annually, which can be grouped into those presenting with tachyarrhythmic (shockable) rhythms and those presenting with non-tachyarrhythmic rhythms. The incidence of tachyarrhythmic rhythms, which include ventricular fibrillation (VF) and pulseless ventricular(More)
Non-small-cell lung cancer (NSCLC) has one of the highest death rates among the various forms of cancer. In attempts to improve on this unsatisfactory outcome, different radiation schedules and chemotherapy agents have been examined in phase II or III studies. These have led to modest improvements in local control and survival, but combined therapies are(More)
DISCUSSION This case is reported to highlight the possibility of erosion and pseudoaneurysm formation after implantation of the FloWatch-PAB adjustable PA banding system. As far as we are aware, this is the second such complication with this device. The previous reported case had a similar complication, with pseudoaneurysm formation 7 weeks after the(More)
A morphometric study of argyrophilic Amine Precursor Uptake and Decarboxylase (APUD) cells in airways and intestine of guinea pigs after hypothalamic lesions is reported. APUD cell densities are expressed as APUD cell number/mm of airway or gut perimeter length and as APUD cell/100 epithelial cells. The latter ratio is useful to distinguish generalized(More)
Compensatory growth is mediated by multiple cell types that interact during organ repair. To elucidate the relationship between stem/progenitor cells that proliferate or differentiate and somatic cells of the lung, we used a novel organotypic ex vivo pneumoexplant system. Applying this technique, we identified a sustained culture of repopulating adult(More)
OBJECTIVES Cardiac involvement in the course of acute kidney injury is described in humans as cardiorenal syndrome type 3 but has received only limited attention in dogs. This study was designed to evaluate cardiac injury and dysfunction in acute kidney injury in dogs and its association with outcome. METHODS This prospective cohort study enrolled 24(More)
The presence of spontaneous muscle activity was determined by analysis of the power spectra of computer-model-generated sequences of spontaneous activity and additive noise. The modeling results identified the frequency band of 100-300 Hz as the band of peak signal-to-noise ratio for the detection of fibrillation potentials. Animal experiments were(More)
