Le bassin du Kou, situé dans le sud-ouest du Burkina Faso, est depuis quelques décennies le théâtre de différentes formes de conflits liés à toute une série de problèmes que l’on rencontre généralement dans des zones irriguées. Dans le bassin du Kou, les aménagements hydroagricoles recensés couvrent une superficie totale de près de 3.200 ha. Il s’agit pour l’essentiel de périmètres privés formant la ceinture maraîchère, horticole et fruitière de Bobo-Dioulasso et d’un grand périmètre de 1.200 ha réalisé par l’Etat à Bama et spécialisé dans la production du riz. Outre l’abondance en eau liée à la présence de sources importantes, d’une nappe phréatique facilement exploitable, d’un cours d’eau pérenne et un hivernage à caractère sub-humide, la plupart des utilisateurs d’eau se retrouvent régulièrement en pénurie d’eau à cause d’une augmentation de la population et d’une intensification de l’agriculture irriguée. Ceci conduit les gestionnaires du bassin à rechercher des outils de contrôle et de suivi. [less ▲]

The urinary bladder of four dogs with emphysematous cystitis was assessed radiographically. Ultrasonography was also performed using a 7.5-MHz microconvex probe in dorsal recumbency and in a standing position. Ultrasonographically there were bright echoes and reverberations typical of gas in all dogs. This was entrapped in the bladder wall as it appeared in the same location in recumbent and standing positions. Bladder size was reduced and bladder content was echogenic in all dogs. In only one out of the four dogs was a gas stripe seen in the bladder on radiographs. Proteus mirahilis was isolated from the urine of all patients. Diabetes was ruled out on the basis of urine and blood analysis. A small amount of gas can be difficult to detect on radiographs. Ultrasonography appears to be a more sensitive technique for detection of gas within the bladder at an early stage of emphysematous cystitis. Prevalence of emphysematous cystitis may be underestimated if only radiographs are made. [less ▲]

BACKGROUND: Physical inactivity is a major atherosclerosis risk factor. The exercise tolerance is usually excellent after neonatal arterial switch operation, but those patients in whom coronary anomalies remain the main late complication, risk developing atherosclerotic coronary disease owing to perceived physical activity restrictions. METHODS: We investigated physical activity patterns of 52 unselected children 7 to 14 years after neonatal arterial switch operation for transposition of the great arteries by 24-hour continuous heart rate monitoring. The percentage of heart rate reserve was used to measure the amounts of activities. Comparisons were made with 35 children with repaired atrial or ventricular septal defect and with 127 age-matched healthy children. RESULTS: Children after arterial switch operation accumulated 167.3 +/- 70.6, 25.3 +/- 12.9, and 15.7 +/- 11.3 minutes a day (mean +/- SD) of light, moderate, and vigorous physical activities, respectively. At the same activity levels, children with repaired septal defect accumulated 165.2 +/- 82.2, 26.2 +/- 11.7, and 16.2 +/- 9.1 minutes a day, and their healthy peers 164.8 +/- 74.5, 31.8 +/- 13.9, and 21.9 +/- 11.3 minutes a day. Both cardiac groups were significantly less active than the control group when considering moderate (p = 0.026) and vigorous activities (p = 0.006). Only 19% and 27% of the children after arterial switch operation engaged, respectively, in more than 30 minutes a day of moderate activity and 20 minutes a day of vigorous activity. CONCLUSIONS: Children after arterial switch operation, just like other cardiac children, do not meet the guidelines for physical activity. We should encourage regular physical activity to offset adult sedentary behavior and to prevent atherosclerotic cardiovascular disease in those patients whose long-term function of the coronary arteries remains a matter of concern.

Testosterone (T) influences the volume and cellular characteristics of a variety of steroid-dependent brain nuclei in many vertebrates. In castrated quail, the volume of the sexually dimorphic (males > females) medial preoptic nucleus (POM), a key area in the control of male sexual behavior, is markedly increased by T but previous studies always assessed this effect after a period of 8-14 days and its specific time-course was unknown. We recently found that following treatment with T, the POM volume increases in a time-dependent fashion: a significant increase was already detected after only one day and the response reached it maximum (volume doubling) after 14 days of treatment. This however raised the question of the cellular mechanism underlying such a rapid brain plasticity (increase in cell size, neuropil volume, dendritic branching, extracellular space?). To research whether a change in extra- vs. intra-cellular space could be responsible for the rapid T-induced increase in POM volume, we repeatedly analyzed by in vivo diffusion-weighted magnetic resonance imaging (DW-MRI) the brain of castrated male quail before as well as after 1, 2, 7 and 14 days of T implantation. MRI was performed on a 7T-system (Bruker) using a multislice diffusion weighted-spin echo sequence. Coronal slices with an image resolution of 100*100*500µm³ were obtained covering the whole telencephalon. Images were accurately coregistered allowing voxel-wise paired comparisons of the ADC data between the different time periods. The ADC significantly increased after one day of T treatment (696±16 vs 758±30 µm²/s, p=0.011, N=5) in POM and this effect apparently persisted during the whole experiment. By contrast, T insensitive regions like the nucleus rotundus (586±170 vs 511±26 µm²/s, p-value=0.24) and nucleus mesencephalicus lateralis, pars dorsalis (934±107 vs 911±64 µm²/s, p=0.68) were not affected after the first day nor later in the experiment. These data indicate that T increases the extracellular water volume in POM specifically, either as a result of cell shrinkage or of an increase in the space between cells, and that changes in the ratio of extra- to intra-cellular water mediate, at least in part, the fast plasticity of the POM volume observed after exposure to T.

In order to achieve the harmonization of validation strategies, the interpretation of several validation criteria is proposed. Furthermore, a simple and visual decision tool to assess the validity of an analytical procedure is described: the accuracy profile based on the estimation of the total error of the measurements. This profile build with beta-expectation tolerance intervals can also compute with efficiency the uncertainty related to the results of a laboratory, which is an essential parameter for the accreditation of laboratories under ISO 17025.

In white matter disorders such as leukodystrophies (LD), periventricular leucomalacia (PVL), or multiple sclerosis (MS), the hypomyelination or the remyelination failure by oligodendrocyte progenitor cells involves errors in the sequence of events that normally occur during development when progenitors proliferate, migrate through the white matter, contact the axon, and differentiate into myelin-forming oligodendrocytes. Multiple mechanisms underlie the eventual progressive deterioration that typifies the natural history of developmental demyelination in LID and PVL and of adult-onset demyelination in MS. Over the past few years, pathophysiological studies have mostly focused on seeking abnormalities that impede oligodendroglial maturation at the level of migration, myelination, and survival. In contrast, there has been a strikingly lower interest for early proliferative and differentiation events that are likely to be equally critical for white matter development and myelin repair. This review highlights the Yin and Yang principles of interactions between intrinsic factors that coordinately regulate progenitor cell division and the onset of differentiation, i.e. the initial steps of oligodendrocyte lineage progression that are obviously crucial in health and diseases.

In the framework of a Euratom research program devoted to Nuclear Waste deposition security assessment, a numerical simulation of the excavation of a gallery in the Boom Clay layer at Mol (Belgium) has been performed In order to model the progressive excavation and lining installation process, a special sequence of desactivation/activation of sets of elements was elaborated. In particular, this numerical strategy allowed to take into account the fact that, due to the deformation of the massif as the excavation progresses, the material to be excavated once the front has reached a given position into the rock mass cannot be defined a priori, but is resulting of the modelling of the previous phases up to the present one.
