Relationships between plasma lipids, proteins, surface tension and post-dive bubbles
Article scientifiqueDecompression sickness (DCS) in divers is caused by bubbles of inert gas. When DCS occurs, most bubbles can be found in the venous circulation: venous gas emboli (VGE). Bubbles are thought to be stabilized by low molecular weight surfactant reducing the plasma-air surface tension (γ). Proteins may play a role as well. We studied the interrelations between these substances, γ and VGE, measured before ... -
The "normobaric oxygen paradox": a new tool for the anesthetist?
10 janvier 2014, Rocco, Monica; Ditri, Luciano; De Bels, David; Corazza, Francis; BALESTRA, Costantino
, HE Bruxelles Brabant
Article scientifiqueHypoxia is the natural trigger for endogenous EPO production but recently the use of intermittent hyperoxia to stimulate EPO has been postulated and this phenomenon has been called the "normobaric oxygen paradox" (NOP). The "NOP" is a mechanism by which oxygen regulates the expression of the Hypoxia Inducible Factor 1 alpha (HIF-1alpha). The HIF-1alpha-depending gene regulation is responsible for ... -
Fluoxetine stimulates anti-inflammatory IL-10 cytokine production and attenuates sensory deficits in a rat model of decompression sickness
22 octobre 2015, HE Bruxelles BrabantArticle scientifiqueDespite "gold standard" hyperbaric oxygen treatment, 30% of patients suffering from neurological decompression sickness still exhibit incomplete recovery, including sensory impairments. Fluoxetine, a well-known antidepressant, is recognized as having anti-inflammatory effects in the setting of cerebral ischemia. In this study, we focused on the assessment of sensory neurological deficits and measurement ... -
Age, weight and decompression sickness in rats
16 mars 2016, HE Bruxelles BrabantArticle scientifiqueObjective: The aim of this study was to determine if, after controlling for weight, age is associated with decompression sickness (DCS) in rats. Methods: Following compression-decompression, male rats aged 11 weeks were observed for DCS. After two weeks recovery, surviving rats were re-dived using the same compression-decompression profile. Results: In this experiment, there was a clear difference ... -
Cognitive factors in women hypoactive sexual desire disorder
janvier 2013, HE Léonard de VinciArticle scientifiqueLe désir sexuel hypoactif (DSH) est une difficulté largement répandue parmi les femmes. Le concept de désir sexuel ainsi que ses dysfonctionnements sont difficiles à définir en raison de la dimension subjective importante. À cause de cette composante subjective, les facteurs psychologiques, et en particulier les dimensions cognitives, sont susceptibles de jouer un rôle important dans le développement ... -
Do stressful life events impact women's sexual desire?
15 novembre 2017, HE Léonard de VinciArticle scientifiquePeople confronted to a stressful life event may experience negative consequences on sexual intimacy (Morokoff and Gillilland, 1993; Hagemeister and Rosenblatt, 1997, Bodenmann et al., 2006). The main hypothesis of the study is that the impact of stressful events on sexuality, especially on sexual desire, will depend on the subjective reactions to this event. Fifty-two women responded to several ... -
Colonic Fermentation Promotes Decompression sickness in Rats
08 février 2016, HE Bruxelles BrabantArticle scientifiqueMassive bubble formation after diving can lead to decompression sickness (DCS). During dives with hydrogen as a diluent for oxygen, decreasing the body's H2 burden by inoculating hydrogen-metabolizing microbes into the gut reduces the risk of DCS. So we set out to investigate if colonic fermentation leading to endogenous hydrogen production promotes DCS in fasting rats. Four hours before an experimental ... -
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 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 ... -
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 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 ... -
Mechanism of action of antiplatelet drugs on decompression sickness in rats: a protective effect of anti-GPIIbIIIa therapy
15 mai 2015, HE Bruxelles BrabantArticle scientifiqueLiterature highlights the involvement of disseminated thrombosis in the pathophysiology of decompression sickness (DCS). We examined the effect of several antithrombotic treatments targeting various pathways on DCS outcome: acetyl salicylate, prasugrel, abciximab, and enoxaparin. Rats were randomly assigned to six groups. Groups 1 and 2 were a control nondiving group (C; n = 10) and a control diving ... -
Flying after diving: should recommendations be reviewed? In-flight echocardiographic study in bubble-prone and bubble-resistant divers
13 mai 2015, Cialoni, Danilo; Pieri, Massimo; BALESTRA, Costantino; Marroni, Alessandro, HE Bruxelles Brabant
Article scientifiqueINTRODUCTION: Inert gas accumulated after multiple recreational dives can generate tissue supersaturation and bubble formation when ambient pressure decreases. We hypothesized that this could happen even if divers respected the currently recommended 24-hour pre-flight surface interval (PFSI). METHODS: We performed transthoracic echocardiography (TTE) on a group of 56 healthy scuba divers (39 male, ... -
Cutis Marmorata skin decompression sickness is a manifestation of brainstem bubble embolization, not of local skin bubbles
10 avril 2015, Germonpré, Peter; BALESTRA, Costantino; Obeid, Georges; Chers, Dirk, HE Bruxelles Brabant
Article scientifique"Cutis Marmorata" skin symptoms after diving, most frequently in the form of an itching or painful cutaneous red-bluish discoloration are commonly regarded as a mild form of decompression sickness (DCS), and treated with oxygen inhalation without reverting to hyperbaric recompression treatment. It has been observed that the occurrence of Cutis Marmorata is frequently associated with the presence of ...
