A Combined In Vivo and In Vitro Approach to the Study of Endotoxemia in Swine
The cardiopulmonary effects of endotoxin administration (1 microgram/kg) were evaluated in 8-10 week old SPF-derived Yorkshire pigs, both because endotoxemia is a common and important swine problem, and because the pig is a good model for human adult respiratory distress syndrome. Physiological …

The bone cement implantation syndrome - epidemiology, pathophysiology and prevention
… to prevent or reduce the risk of severe cardiopulmonary impairment due to BCIS are investigated. A retrospective investigation of 1,016 patients who underwent cemented hip hemiarthroplasty due to displaced femoral neck fracture revealed a total incidence of BCIS of 28% (283/1,016 patients), …

Effekte des intraabdominellen Drucks auf respiratorische Parameter und den Gasaustausch unter druckkontrollierter versus assistierter Beatmung mit BIPAP
… superior respiratory mechanics and cardiovascular stability as compared to BIPAPPC. Although the decrease of dynamic compliance and the increase of airway pressures were mitigated, BIPAPSB failed to lower pulmonary vascular resistance and caused increased dead space ventilation (p=0.007). …

Etablierung eines modifizierten Adriamycin-induzierten Herzinsuffizienzmodells am Schwein
… increase of the central venous pressure, pulmonary artery pressure, pulmonary wedge pressure, and pulmonary vascular resistance, whereas cardiac output, stroke volume index, and left ventricular stroke work index decreased. These results were supported by the echocardiographic data …

Liposomal delivery of PDE5 inhibitors and UT-15C to human erythrocytes
… is an important mechanism for the regulation of vascular caliber. However, erythrocytes from patients with pulmonary arterial hypertension (PAH) fail to release ATP in response to the physiological stimuli of exposure to low oxygen tension or mechanical deformation of a magnitude these cells …

Molecular and cellular mechanisms implicated in the regulation of cellular PMCA expression during pulmonary arterial hypertension
Pulmonary arterial hypertension (PAH) is a rare, life-threatening disorder typified by elevated pulmonary vascular resistance, right ventricular hypertrophy, right heart failure and ultimately death. This disease has no current cure and available therapies alleviate vasoconstriction but do not …

L'ecocardiografia da sforzo come metodica di studio del circolo polmonare
Il circolo polmonare è un distretto vascolare caratterizzato da basse pressioni ed elevati flussi. L'equilibrio tra pressioni e flussi normalmente vigente in questo distretto può essere alterato da diverse condizioni fisiologiche e patologiche. L esercizio fisico rappresenta uno stress …

Interactions between potassium channels and serotonin in pulmonary arterial hypertension
Pulmonary arterial hypertension (PAH) is a progressive disease which results from increases in mean pulmonary artery pressure and pulmonary vascular resistance. If untreated it leads to right ventricular failure and death. 5-Hydroxytryptamine (5-HT) has been implicated in the disease process and is …

Investigation of the intracellular pathways required for 5HT-induced mitogenesis and their role in pulmonary hypertension.
ABSTRACT Pulmonary arterial hypertension (PAH) is a rare and progressive disease characterised by increased pulmonary vascular resistance and elevated pulmonary artery pressure, leading to right ventricular failure and eventually death. The monoamine 5-hydroxytryptamine (5HT) has been implicated in …

Αιμοδυναμικές και αναπνευστικές επιδράσεις της θειϊκής πρωταμίνης σε σχέση με την οδό και τον ρυθμό χορήγησης: Πειραματική μελέτη
… monitoring and blood sampling. A thermodilution pulmonary artery catheter was inserted through the left femoral vein for calculation of cardiac output, measurement of pulmonary vascular pressures and sampling of mixed venous blood. Through the ventilatory circuit, end-tidal CO₂ and compliance …

Deep forward and reverse phenotyping for genetic discovery in pulmonary arterial hypertension.
Pulmonary arterial hypertension (PAH) is a rare disease characterised by constriction and obliteration of small pulmonary arteries, which leads to increased pulmonary vascular resistance and in consequence, right ventricular failure and death. The accurate clinical diagnosis of pulmonary …
