Normobaric oxygen can enhance protein captation by the lymphatic system in healthy humans.
janvier 2004, HE Bruxelles BrabantArticle scientifiquehas been advocated for a long time. Several beneficial effects of NBO have been demonstrated, one of which is the faster elimination of tissue nitrogen bubbles. During DCS occurrence, a cascade of intravascular reactions has been demonstrated. These inflammatory reactions occur within minutes of the onset of DCS, and involve the precipitation of proteins on the gas-bubble interface, causing a ... -
The fractal approach as a tool to understand asymptomatic brain hyperintense MRI signals
2004, HE Bruxelles BrabantArticle scientifiqueThe prevalence of a Patent Foramen Ovale is described in merely 30% of the asymptomatic population. This patency has been shown to be an increasing risk factor for paradoxical cerebral embolization. Some desaturation or decompression situations in human activities such as scuba diving or altitude flight are prone to provoke embolisations. The association with the presence of a patent Foramen Ovale ... -
Evidence for increasing patency of the foramen ovale in divers
2005, HE Bruxelles BrabantArticle scientifiquesing a standardized contrast-enhanced transesophageal echocardiographic technique, a group of divers was reexamined for the presence and size of patent foramen ovale (PFO) 7 years after their initial examinations. Unexpected but significant increases in the prevalence and size of PFO were found, suggesting a possible increasing risk for decompression sickness in these divers over time. -
A deep stop during decompression from 82 fsw (25 m) significantly reduces bubbles and fast tissue gas tensions.
janvier 2004, HE Bruxelles BrabantArticle scientifiquen spite of many modifications to decompression algorithms, the incidence of decompression sickness (DCS) in scuba divers has changed very little. The success of stage, compared to linear ascents, is well described yet theoretical changes in decompression ratios have diminished the importance of fast tissue gas tensions as critical for bubble generation. The most serious signs and symptoms of DCS ... -
Erythropoietin production can be enhanced by normobaric oxygen breathing in healthy humans
2004, HE Bruxelles BrabantArticle scientifiqueErythropoietin (EPO) induces red blood cell production by activating red bone marrow progenitor cells, and is used therapeutically in chronic anemia. It is also used as an unauthorized adjunct to increase the oxygen transport capacity in the blood of athletes. Renal tissue hypoxia is the only widely accepted trigger for EPO production (1-3), even if new oxygen-sensitive sites have been recently ... -
Scuba diving can induce stress of the temporomandibular joint leading to headache [1]
2004, HE Bruxelles BrabantArticle scientifiqueIn ordinary recreational scuba diving, many anatomical parts can be involved in disorders of cranial regions: ears and eyes are involved but also sinuses. Dental problems are generally involved in barotraumas because of bad dental fillings or other matters of interest to the general dental practitioner.1 Very few papers have looked at the articular and periarticular problems of the temporomandibular joint ... -

ACTIVLIM-CP a new Rasch-built measure of global activityperformance for children with cerebral palsy
2016, HE Léonard de VinciHE Louvain en HainautArticle scientifiqueObjective Children with cerebral palsy (CP) often have upper extremity (UE) and lower extremity (LE) impairments. While tools measuring separately UE and LE abilities are currently used, activities in which UE and LE are used in combination – numerous in everyday life – cannot be assessed because no instrument allows capturing global activity performance in children with CP. This study aimed to ... -
Brain activation changes following motor training in children with unilateral cerebral palsy: An fMRI study
2021, HE Léonard de VinciArticle scientifiqueBACKGROUND: Intensive motor-learning-based interventions have demonstrated efficacy for improving motor function in children with unilateral spastic cerebral palsy (USCP). Although this improvement has been associated mainly with neuroplastic changes in the primary sensori-motor cortices, this plasticity may also involve a wider fronto-parietal network for motor learning. OBJECTIVE: To determine ... -
