Respiratory changes resulting from stepwise intrathoracic injections of 4 ml of either room air or warm (37 degrees C) Haemaccel, simulating pneumothorax and pleural effusion, respectively, were evaluated in anaesthetized, paralysed, and mechanically-ventilated rats. Respiratory system, lung, and chest wall resistances and elastances (static and dynamic)(More)
Infection with Bartonella spp may cause cardiac arrhythmias, myocarditis and endocarditis in humans. The aim of the present study was to evaluate a possible association between Bartonella spp bacteremia and endocarditis, arrhythmia and Chagas cardiomyopathy in patients from Brazil and Argentina. We screened for the presence of bacterial 16S rRNA in human(More)
The purpose of the present study was to determine the mechanical respiratory profile after the insertion of a catheter into the pleural cavity of anesthetized, paralyzed, mechanically ventilated rats, thus stimulating the common use of chest tubes in clinical situations. Using the method of end-inflation occlusion during constant inspiratory flow in 7 adult(More)
