Patients with chronic airflow obstruction and difficult weaning from mechanical ventilation are at increased risk for intubation-associated complications and mortality because of prolonged invasive mechanical ventilation. Non-invasive positive-pressure ventilation (NPPV) may revert most of the pathophysiologic mechanisms associated with weaning failure in these patients. Several randomised cont...

BACKGROUND The association between echocardiographic structural parameters and body weight (BW) during rat development has been poorly addressed. We evaluated echocardiographic variables: left ventricular (LV) end-diastolic (LVDD) and end-systolic (LVSD) diameters, LV diastolic posterior wall thickness (PWT), left atrial diameter (LA), and aortic diameter (AO) in function of BW during developme...

METHODS A national-level male competitive cyclist completed 3 laboratory cycling tests: a su...

The families of locally testable (LT ) and piecewise testable (PWT ) languages have been deeply studied in formal language theory. They have in common that the role played by the segments of length k of their words in the first family is played in the second by their subwords (sequences of non necessarily consecutive symbols), also of length k. We propose algorithms that, given k > 0, identify ...
