EPR spectroscopic evidence of iron-catalysed free radical formation in chronic mountain sickness : dietary causes and vascualr consequences
Bailey, Damian M; Culcasi, Marcel; Filipponi, Teresa; Brugniaux, Julien V; Stacy, Benjamin S; Marley, Chistopher J; Soria, Rodrigo; Rimoldi, Stefano F; Cerny, David; Rexhaj, Emrush; Pratali, Lorenza; Salinas Salmón, Carlos; Murillo Jáuregui, Carla; Villena, Mercedes; Villafuerte, Francisco; Rockenbauer, Antal; Pietri, Sylvia; Scherrer, Urs; Sartori, Claudio (Free Radical Biology and Medicine, 2022)Abstract Chronic mountain sickness (CMS) is a high-altitude (HA) maladaptation syndrome characterised by elevated systemic oxidative-nitrosative stress (OXNOS) due to a free radical-mediated reduction in vascular nitric ... -
Exaggerated exercise-induced pulmonary hypertension causes lung water accumulation and right ventricular dysfunction in patients with chronic mountain sickness
Pratali, Lorenza; Rimoldi, Stefano F; Rexhaj, Emrush; Salinas Salmón, Carlos E; Villena, Mercedes; Sicari, Rosa; Picano, Eugenio; Scherrer, Urs; Allemann, Yves; Sartori, Claudio (High Altitude Medicine & Biology, 2010-08-08) -
Exaggerated pulmonary hypertension and right ventricular dysfunction in high-altitude dwellers with patent foramen ovale
Brenner, Roman; Pratali, Lorenza; Rimoldi, Stefano F; Murillo Jauregui,Carla Ximena; Soria, Rodrigo; Rexhaj, Emrush; Salinas Salmón, Carlos; Villena, Mercedes; Romero, Catherine; Sartori, Claudio; Allemann, Yves; Scherrer, Urs (Chest, 2015)There is considerable interindividual variability in pulmonary artery pressure among high-altitude (HA) dwellers, but the underlying mechanism is not known. At low altitude, a patent foramen ovale (PFO) is present in about ... -
Exaggerated systemic oxidative-inflammatory-nitrosative stress in chronic mountain sIckness is associated with cognitive decline and depression
Bailey, Damian M; Brugniaux, Julien V; Filipponi, Teresa; Marley, Christopher J; Stacey, Benjamin; Soria, Rodrigo; Rimoldi, Stefano F; Cerny, David; Rexhaj, Emrush; Pratali, Lorenza; Salinas Salmón, Carlos; Murillo Jáuregui, Carla; Villena, Mercedes; Smirl, Jonathan D; Ogoh, Shigehiko; Pietri, Sylvia; Scherrer, Urs; Sartori, Claudio (J Physiol, 2019)Abstract. Chronic mountain sickness (CMS) is a maladaptation syndrome encountered at high altitude (HA) characterised by severe hypoxaemia that carries a higher risk of stroke and migraine and is associated with increased ... -
Exercise induces rapid interstitial lung water accumulation in patients with chronic mountain sickness
Pratali, Lorenza; Rimoldi, Stefano F; Rexhaj, Emrush; Hutter, Damian; Faita, Francesco; Salinas Salmón, Carlos E; Villena, Mercedes; Sicari, Rosa; Picano, Eugenio; Allemann, Yves; Scherrer, Urs; Sartori, Claudio (CHEST, 2012-04-04)Background: Chronic mountain sickness (CMS) is a major public health problem in mountainous regions of the world. In its more advanced stages, exercise intolerance is often found, but the underlying mechanism is not ... -
Oxidative-nitrosative stress and systemic vascular function in highlanders with and without exaggerated hypoxemia
Bailey, Damian M; Rimoldi, Stefano F; Rexhay, Emrush; Pratali, Lorenza; Salinas Salmón, Carlos; Villena, Mercedes; McEneny, Jane; Young, Ian S; Nicod, Pascal; Allemann, Yves; Scherrer, Urs; Sartori, Claudio (CHEST, 2013-02-01)Background: Acute exposure to high altitude stimulates free radical formation in lowlanders, yet whether this persists during chronic exposure in healthy, well-adapted and maladapted highlanders suffering from chronic ... -
RV contractility and exercise-induced pulmonary hypertension in chronic mountain sickness : a stress echocardiographic and tissue doppler imaging study
Pratali, Lorenza; Allemann, Yves; Rimoldi, Stefano F; Faita, Francesco; Hutter, Damian; Rexhaj, Emrush; Brenner, Roman; Bailey, Damian M; Sartori, Claudio; Salinas Salmón, Carlos E; Villena, Mercedes; Scherrer, Urs; Picano, Eugenio; Sicari, Rosa (ELSEVIER, 2013-12)Objectives. The aim of this study was to evaluate right ventricular (RV) and left ventricular function and pulmonary circulation in chronic mountain sickness (CMS) patients with rest and stress echocardiography compared ... -
Sleep-disordered breathing and vascular function in patients with chronic mountain sickness and healthy high-altitude dwellers
Rexhaj, Emrush; Rimoldi, Stefano F; Pratali, Lorenza; Brenner, Roman; Andries, Daniela; Soria, Rodrigo; Salinas Salmón, Carlos; Villena, Mercedes; Romero, Catherine; Allemann, Yves; Lovis, Alban; Heinzer, Raphaël; Sartori, Claudio; Scherrer, Urs (CHEST, 2016-11-05)BACKGROUND: Chronic mountain sickness (CMS) is often associated with vascular dysfunction, but the underlying mechanism is unknown. Sleep-disordered breathing (SDB) frequently occurs at high altitude. At low altitude, ... -
