We report here the nucleotide sequence corresponding to two large regions of the hepatitis A virus (HAV) genome. These comprise a sequence of 3274 bases corresponding to the 5' end of the genome, which includes the putative capsid protein region of this picornavirus, and 1590 bases corresponding to the 3' end of the genome, terminating in a 15-base poly(A)(More)
Echocardiography represents the non-invasive tool most commonly used in pediatric cardiology. Indeed, it enables the definition of both the morphological and functional findings in congenital heart disease (CHD), as completely as possible in almost all the cases. In comparison with adult subjects, the echocardiographic evaluation in pediatric patients(More)
BACKGROUND Several clinical and echocardiographic studies describe morphological and functional findings in patients with hypertrophic cardiomyopathy. Less is known regarding morphological and functional characteristics of the left ventricular hypertrophy found in the setting of the Noonan and LEOPARD syndromes. OBJECTIVE To compare non-invasively the(More)
The pathogenesis of experimental hepatitis E has not been thoroughly investigated. The purpose of this study was to more accurately document the events in this disease. Cynomolgus macaques were inoculated intravenously with bile or feces containing hepatitis E virus (HEV). Serum, bile, and liver specimens were evaluated with light microscopy, immune(More)
BACKGROUND The aim of this study was to identify non-invasively the potential impact of pulmonary regurgitation and age at surgical repair on the right ventricular (RV) textural and functional myocardial properties in patients operated on for tetralogy of Fallot (TOF). METHODS We assessed the average intensity (Int.(1B)) and the cyclic variation (CV(IB))(More)
Sensitive and specific methods are needed to detect hepatitis A virus (HAV) and other human enteroviruses in environmental samples such as drinking water and foods. Clones of cDNA encoding the 5'-most 1 kb of the HAV and coxsackievirus B3 (CB3) genomes were subcloned into T7/SP6 RNA transcription vectors. In vitro transcribed RNA from the T7 promoter(More)
Cardiotrophin-1 (CT-1) is a member of the interleukin (IL-6) family of cytokines. Plasma CT-1 levels correlate with the left ventricle mass index in patients with dilatated cardiomyopathy and congestive heart failure (CHF). The aim of this paper was to evaluate CT-1 plasma levels, before and after cardiac resynchronization therapy CRT, and to(More)
Over the last decades, there has been a significant increase in incidence and prevalence of heart failure, a major cause of cardiac morbidity and mortality. Measurements of neurohormones, in particular B-type natriuretic peptide (BNP), can significantly improve diagnostic accuracy, and also correlate with long-term morbidity and mortality in patients with(More)
BACKGROUND Based on color Doppler methodology, regional myocardial strain rate (SR) and strain (epsilon) can now be calculated by comparing local myocardial velocity profiles. These deformation data sets may be an important new approach to quantify regional function of the left or right ventricle in congenital heart disease. The aim of the present study was(More)
We report a severe, biventricular obstructive cardiomyopathy in a young female with Costello syndrome, who underwent a right ventricular myectomy for symptoms relief. We discuss potential clinical implications and management of severe hypertrophy in Costello syndrome.
