Aggregation is a serious obstacle for recovery of biologically active heterologous proteins from inclusion bodies (IBs) produced by recombinant bacteria. E. coli transformed with a vector containing the cDNA for Bothropstoxin-1 (BthTx-1) expressed the recombinant product as IBs. In order to obtain the native toxin, insoluble and aggregated protein was refolded using high hydrostatic pressure (HHP)...
Aim of this paper is to study unexpected electrical activities seldom observed during the diastolic interval of intracardiac electrograms (EGM) retrieved from patients with implantable cardioverter defibrillators (ICD). Five patients are considered. From them 29 EGM are retrieved in different cardiac conditions: 18 immediately before ventricular tachyarrhythmia (VT-EGM) initiation, and 11 in basal...
Coronary artery disease (CAD) and dilated cardiomyopathy (DCM) are structurally different heart diseases. Spontaneous ventricular tachyarrhythmias (VT) from implantable cardio-defibrillators (ICD) are studied to explore clinical differences between CAD and DCM. The analysis is focused on: number of VT episodes, variability of the VT onset (three modes are considered), VT-rate, coupling interval, prematurity...
This study investigates circadian distribution of ventricular tachyarrhythmias (VT) in coronary artery disease (CAD) and dilated cardiomyopathy (DCM) patients that received an implantable cardioverter defibrillator (ICD) as secondary prevention. 37 patients are studied. Times of VT episode are retrieved from data log of the ICD; the analysis includes the separation of different modes of VT-onset....
Abstract Ventricular tachyarrhythmia (VT) onset is studied by reviewing spontaneous intracardiac electrograms (EGMs) from coronary artery disease (CAD) and dilated cardiomyopathies (DCM) patients with implantable cardioverter-defibrillators (ICD). A total of 165 VT episodes (79 CAD and 86 DCM) from 37 patients (26 CAD and 11 DCM) are analysed. Modes of VT onset are divided into: (i) premature ventricular...
This explorative study focuses on differences between the onset of spontaneous ventricular tachyarrhythmias (VT) of patients with implantable cardioverter defibrillator (ICD) and affected by coronary artery disease (CAD) or dilated cardiomyopathy (DCM). From 57 patients (40 CAD and 17 DCM), 35 (24 CAD and 11 DCM) we retrieved a total of 154 spontaneous VTs (72 CAD and 82 DCM). Three modes of VT onset...
Implantable cardioverter defibrillators (ICDs) can store intracardiac electrograms (EGMs) with 2 modes of recording: bipolar (BIP) or far-field (FF). Aims of this study are: (i) to propose a non conventional cardiac electrical activity characterization (CEAC); (ii) to investigate the mode of recording that better allows retrieving information from measured EGMs with CEAC. We consider 293 EGMs during...
Objective We tested the hypothesis that management of patients with syncope admitted urgently to a general hospital may be influenced by the presence of an in-hospital structured syncope unit.Background The management of syncope is not standardized.Methods We compared six hospitals equipped with a syncope unit organized inside the department of cardiology with six matched hospitals without such facilities...
