05 août 2018, Bosco, Gerardo; Quartesan, Silvia; Mrakic-Sposta, Simona; Moretti, Sarah; BALESTRA, Costantino; Rubini, Alessandro, HE Bruxelles Brabant
Article scientifiqueIntroduction: Hyperbaric oxygen (HBO(2)) therapy and use of enriched air can result in oxidative injury affecting the brain, lungs and eyes. HBO(2) exposure during diving can lead to a decrease in respiratory parameters. However, the possible effects of acute exposure to oxygen-enriched diving on subsequent spirometric performance and oxidative state in humans have not been recently described recently. ... -
Pre-dive Whole-Body Vibration Better Reduces Decompression-Induced Vascular Gas Emboli than Oxygenation or a Combination of Both
30 novembre 2016, BALESTRA, Costantino; ; Papadopoulou, Virginie; Le Mener, Cédric; ; Guerrero, François; Lafère, Pierre, HE Bruxelles Brabant
Article scientifiquePurpose: Since non-provocative dive profiles are no guarantor of protection against decompression sickness, novel means including pre-dive "preconditioning" interventions, are proposed for its prevention. This study investigated and compared the effect of pre-dive oxygenation, pre-dive whole body vibration or a combination of both on post-dive bubble formation. Methods: Six healthy volunteers performed ... -

Article scientifiqueIn situ evaluation of human brain performance and arousal remains challenging during operational circumstances, hence the need for a rapid, reliable and reproducible tool. Here we hypothesized that the Critical flicker fusion frequency (CFFF) reflecting/requiring visual integration, visuo-motor skills and decision-taking process might be a powerful, fast and simple tool in modified gravity environments. ... -
One-week cocoa flavanol intake increases prefrontal cortex oxygenation at rest and during moderate-intensity exercise in normoxia and hypoxia
12 juillet 2018, Decroix, Lieselot; Tonoli, Cajsa; Lespagnol, Elodie; BALESTRA, Costantino; Descat, Amandine; Drittij-Reijnders, Marie José; Blackwell, Jamie; Stahl, Wilhelm; Jones, Andrew; Wesseler, Antje; Bast, Aalt; Meeusen, Romain; Heyman, Elsa, HE Bruxelles Brabant
Article scientifiqueDuring exercise in hypoxia, O2 delivery to brain and muscle is compromised, and oxidative stress is elicited. Cocoa flavanols (CF) have antioxidant capacities and can increase blood flow by stimulating endothelial function. We aimed to examine the effects of 7-day CF intake on oxidative stress, nitric oxide production, and tissue oxygenation in response to exercise in normobaric hypoxia (14.3% O2). ... -
Commercial Divers' Subjective Evaluation of Saturation
30 janvier 2019, Imbert, Jean Pierre; BALESTRA, Costantino; Kiboub, Fatima Zohra; Loennechen, Øyvind; Eftedal, Ingrid, HE Bruxelles Brabant
Article scientifiqueCommercial saturation diving involves divers living and working in an enclosed atmosphere with elevated partial pressure of oxygen (ppO2) for weeks. The divers must acclimatize to these conditions during compression, and for up to 28 days until decompression is completed. During decompression, the ppO2 and ambient pressure are gradually decreased; then the divers must acclimatize again to breathing ... -

04 avril 2018, Khalife, Maher; Wiams, Kathleen; Ben Aziz, M; BALESTRA, Costantino; Sosnowski, Maurice, HE Bruxelles Brabant
Article scientifiqueErythropoietin (EPO) stimulating agents are known as alternatives to transfusion. However, they expose patients to thrombosis and are expensive. A phenomenon, “the normobaric oxygen paradox” (NOP), has been described. A transient hyperoxia followed by a prolonged return to normoxia acts as an effective trigger for EPO production. The mechanism depends on free O2 radicals and on reduced gluthatione ... -
Hemoglobin and Erythropoietin After Commercial Saturation Diving
21 août 2018, Kiboub, Fatima Zohra; BALESTRA, Costantino; Loennechen, Øyvind; Eftedal, Ingrid, HE Bruxelles Brabant
Article scientifiqueSaturation divers are exposed to elevated partial pressure of oxygen (ppO2) in their hyperbaric work environment. Experimental studies indicate that oxygen transport is altered, and we have previously reported a drop in hematocrit and extensive downregulation of genes involved in blood oxygen transport capacity after decompression from professional saturation diving. Here we investigate the initial ... -
