Effect of decompression-induced bubble formation on highly trained divers microvascular function
07 novembre 2013, HE Bruxelles BrabantArticle scientifiqueWe previously showed microvascular alteration of both endothelium-dependent and -independent reactivity after a single SCUBA dive. We aimed to study mechanisms involved in this postdive vascular dysfunction. Ten divers each completed three protocols: (1) a SCUBA dive at 400 kPa for 30 min; (2) a 41-min duration of seawater surface head immersed finning exercise to determine the effect of immersion ... -
Effect of dietary nitrate supplementation on metabolic rate during rest and exercise in human: A systematic review and a meta-analysis
16 janvier 2016, HE CondorcetArticle scientifiqueBackground Recent randomized controlled trials have suggested that dietary nitrate (NO3-), found in beetroot and other vegetables, and inorganic NO3− salts decrease metabolic rate under resting and exercise conditions. Objective Our aim was therefore to determine from a systematic review and meta-analysis whether dietary NO3− supplementation significantly reduces metabolic rate, expressed as ... -
Effect of dietary nitrate supplementation on tolerance to supramaximal intensity intermittent exercise
29 mai 2015, HE CondorcetArticle scientifiqueDietary nitrate (NO3−) supplementation has been shown to increase exercise tolerance and improve oxidative efficiency during aerobic exercise in healthy subjects. We tested the hypothesis that a 3-day supplementation in beetroot juice (BJ) rich in NO3− would improve the tolerance to supramaximal intensity intermittent exercise consisting of 15-s exercise periods at 170% of the maximal aerobic power ... -

; 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 ... -
Effect of oxygen-breathing during a decompression-stop on bubble-induced platelet activation after an open-sea air dive: oxygen-stop decompression
29 septembre 2013, HE Bruxelles BrabantArticle scientifiquePurpose: We highlighted a relationship between decompression-induced bubble formation and platelet micro-particle (PMP) release after a scuba air-dive. It is known that decompression protocol using oxygen-stop accelerates the washout of nitrogen loaded in tissues. The aim was to study the effect of oxygen deco-stop on bubble formation and cell-derived MP release. Methods: Healthy experienced ... -
The effect of pre-dive ingestion of dark chocolate on endothelial function after a scuba dive
Article scientifiqueObjective: The aim of the study was to observe the effects of dark chocolate on endothelial function after scuba diving. Methods: Forty-two male scuba divers were divided into two groups: a control (n=21) and a chocolate group (n=21). They performed a 33-metres deep scuba-air dive for 20 minutes in a diving pool (Nemo 33, Brussels). Water temperature was 33⁰C. The chocolate group ingested 30 g ... -
Effect of SCUBA Diving on Ophthalmic Parameters
09 mars 2022, Deleu, Laurent; Catherine, Janet; Postelmans, Laurence; BALESTRA, Costantino, HE Bruxelles Brabant
Article scientifiqueBackground and Objective: Several cases of central serous chorioretinopathy (CSC) in divers have been reported in our medical retina center over the past few years. This study was designed to evaluate possible changes induced by SCUBA diving in ophthalmic parameters and especially subfoveal choroidal thickness (SFCT), since the choroid seems to play a crucial role in physiopathology of CSC. Materials ... -
Effect of simulated air dive and decompression sickness on the plasma proteome of rats
12 avril 2016, HE Bruxelles BrabantArticle scientifiquePurpose: Decompression sickness (DCS) is a poorly understood systemic disease caused by inadequate desaturation following a reduction in ambient pressure. Although recent studies highlight the importance of circulating factors, the available data are still puzzling. In this study, we aimed to identify proteins and biological pathways involved in the development of DCS in rats. Experimental design: ... -
Effect of splenectomy on platelet activation and decompression sickness outcome in a rat model of decompression
01 septembre 2014, HE Bruxelles BrabantArticle scientifiqueIntroduction: Splenic platelets have been recognized to have a greater prothrombotic potential than others platelets. We studied whether platelets released by splenic contraction could influence the severity and outcome of decompression sickness (DCS) and bubble-induced platelet activation. Methods: Sixteen, male Sprague-Dawley rats were randomly assigned to either a control or a splenectomized ... -
Effect of tetrahydrobiopterin and exercise training on endothelium-dependent vasorelaxation in SHR
02 juin 2013, Guerrero, François; Sanéo, Thioub; Goanvec, Christelle; ; Feray, Annie; BALESTRA, Costantino; Mansourati, Jacques, HE Bruxelles Brabant
Article scientifiqueWe examined whether the improvement of impaired NO-dependent vasorelaxation by exercise training could be mediated through a BH4-dependent mechanism. Male spontaneously hypertensive rats (SHR, n = 20) and Wistar-Kyoto rats (WKY, n = 20) were trained (Tr) for 9 weeks on a treadmill and compared to age-matched sedentary animals (Sed). Endothelium-dependent vasorelaxation (EDV) was assessed with ... -
Effect of the application of vermicompost and millicompost humic acids about the soybean microbiome under water restriction conditions
04 novembre 2022, HE CondorcetArticle scientifique"This study aimed to evaluate the responses of soybean plants to the application of vermicompost HA (HA-V) and millicompost (HA-M) along with Bradyrhizobium sp. under water restriction. The experiment was carried out in a greenhouse, and the treatments received Bradyrhizobium sp. inoculation with or without the application of HA from vermicompost and millicompost with or without water restriction. ... -
Effective practices for teaching oral language through genres and an instructional program that incorporates them
mai 2021, HE Léonard de VinciArticle scientifiqueThis contribution has a twofold objective: (1) to list effective practices for teaching oral language through genres, based on the latest research findings and (2) to propose a training program that uses these practices. To achieve this aim, we first explore effective practices for teaching oral language through genres, based on the literature. In the second part, we present Itineraries, an instructional ... -

Methods: We examined 17 healthy volunteers, between 18 and 50 years old, at sea level, at 3842 m of hypobaric hypoxia and after return to sea level. Cardiac output (CO) was measured with Doppler transthoracic ... -
Effects of Chemopreventive Natural Compounds on the Accuracy of 8-oxo-7,8-dihydro-2′-deoxyguanosine Translesion Synthesis
08 juillet 2021, HE CondorcetArticle scientifiqueTranslesion synthesis is a DNA damage tolerance mechanism that relies on a series of specialized DNA polymerases able to bypass a lesion on a DNA template strand during replication or post-repair synthesis. Specialized translesion synthesis DNA polymerases pursue replication by inserting a base opposite to this lesion, correctly or incorrectly depending on the lesion nature, involved DNA polymerase(s), ... -
Effects of Electrical Stimulation on Delayed Onset Muscle Soreness (DOMS): Evidences from Laboratory and In-Field Studies
12 septembre 2023, Gussoni, Maristella; Moretti, Sarah; Vezzoli, Alessandra; Genitoni, Valerio; Giardini, Guido; BALESTRA, Costantino; Bosco, Gerardo; Pratali, Lorenza; Spagnolo, Elisabetta; Montorsi, Michela; Mrakic-Sposta, Simona, HE Bruxelles Brabant
Article scientifiqueIntense, long exercise can increase oxidative stress, leading to higher levels of inflammatory mediators and muscle damage. At the same time, fatigue has been suggested as one of the factors giving rise to delayed-onset muscle soreness (DOMS). The aim of this study was to investigate the efficacy of a specific electrical stimulation (ES) treatment (without elicited muscular contraction) on two ... -
