To estimate the cumulative randomized evidence for the overall incidence of bisphosphonates induced jaw osteonecrosis in adjuvant treatment of breast cancer. Systematic review and meta-analysis of randomized clinical trials. Trials were located through PubMed, ISI, Cochrane Library, and major cancer scientific meetings searches. We identified 15 studies(More)
BACKGROUND The development of acute kidney injury (AKI) after adult cardiac surgery is associated with increased morbidity and mortality. Our aim was to assess the risk factors for postoperative AKI and whether the addition of perioperative management variables can improve AKI prediction. METHODS We studied 3,219 patients operated from January 2006 to(More)
It is well known that scorpion venom induces lung lesions and respiratory distress which are usually classified as pulmonary oedema (PO). Tityus discrepans is a scorpion that lives in the north-central area of Venezuela, is the most common source of human envenomation here and produces PO. We studied the action of the venom of Tityus discrepans on whole(More)
Dopamine (DA) increases lung edema clearance by regulating vectorial Na+ transport and Na-K-ATPase in the pulmonary epithelium. We studied the role of the mitogen-activated protein kinase (MAPK)-extracellular signal-regulated kinase (ERK) pathway in the DA regulation of Na-K-ATPase in alveolar epithelial cells (AEC). Incubation of AEC with DA resulted in a(More)
We studied whether the beta-adrenergic agonist, isoproterenol (ISO), regulates Na,K-ATPase in alveolar epithelial cells (AEC) via a mitogen-activated protein kinase (MAPK)/extracellular signaling related kinase (ERK) dependent pathway. ISO increased ERK activity in AEC by 10 min via a beta-adrenergic receptor, protein kinase A (PKA)-dependent mechanism.(More)
PURPOSE To provide a broad perspective concerning the recent use of receiver operating characteristic (ROC) analysis in medical imaging by reviewing ROC studies published in Radiology between 1997 and 2006 for experimental design, imaging modality, medical condition, and ROC paradigm. MATERIALS AND METHODS Two hundred ninety-five studies were obtained by(More)
BACKGROUND Cardiomyopathy is highly heritable but genetically diverse. At present, genetic testing for cardiomyopathy uses targeted sequencing to simultaneously assess the coding regions of >50 genes. New genes are routinely added to panels to improve the diagnostic yield. With the anticipated $1000 genome, it is expected that genetic testing will shift(More)
RATIONALE AND OBJECTIVES The automated classification of sonographic breast lesions is generally accomplished by extracting and quantifying various features from the lesions. The selection of images to be analyzed, however, is usually left to the radiologist. Here we present an analysis of the effect that image selection can have on the performance of a(More)
MOTIVATION The declining cost of generating DNA sequence is promoting an increase in whole genome sequencing, especially as applied to the human genome. Whole genome analysis requires the alignment and comparison of raw sequence data, and results in a computational bottleneck because of limited ability to analyze multiple genomes simultaneously. RESULTS(More)
The purpose of this study was to investigate the effect of a noise injection method on the "overfitting" problem of artificial neural networks (ANNs) in two-class classification tasks. The authors compared ANNs trained with noise injection to ANNs trained with two other methods for avoiding overfitting: weight decay and early stopping. They also evaluated(More)
