Immediate loading of oral implants is of great interest for dental practitioners because with this technique, the treatments are faster and the patients do not have to wear an uncomfortable removable provisional prosthesis. improvement of surgical protocols, brand of implants and surface topography makes this procedure reliable. a recent systematic review report a global survival rate of immediate loaded implants of 96,4% with a maximum follow up of 13 years.

Les industries qui s’intéressent à la culture des micro organismes adaptés aux basses températures sont souvent confrontées à l’incapacité de ces derniers à se développer au delà de 20°C. Cette exigence thermique représente un des obstacles majeurs à leur utilisation à grande échelle. Bien que le phénomène puisse apparaître comme un paradoxe thermodynamique, peu d’études s’y sont réellement intéressées. Par ce travail, nous voudrions apporter une contribution à la compréhension des causes de l’inaptitude des micro-organismes psychrophiles à se développer aux températures modérées. Dans ce contexte, l’étude de la levure psychrophile Rhodotorula aurantiaca A19, choisie comme modèle pour ses caractéristiques technologiques, a été abordée sous différents aspects. Ainsi dans une première partie, nous avons évalué les effets néfastes de la croissance aux températures modérées à différents niveaux cellulaires tant physiologique que morphologique et moléculaire. Les analyses morphologiques nous ont incités à focaliser notre étude sur le métabolisme des acyl CoAs et sur le rôle de ces derniers dans l’inaptitude de R. aurantiaca A19 à se développer aux températures modérées.

Basing on soil and forage analyses and on clinical signs, trace element deficiencies can be expected to occur in Wallonian dairy and beef cattle herds. The aim of this study was to evaluate the trace element status of these herds and to determine whether differences could be demonstrated between dairy and beef herds. Thirty beef cattle herds and 26 dairy cattle herds that presented health problems or production disturbances underwent a close observation combined with blood samples taken from a sample of healthy animals in order to analyse zinc, copper, erythrocytes’ superoxyde dismutase and erythrocytes’ gluthathion peroxidase (selenium’s marker). Multiple deficiencies were detected in 84% of the herds. No significant difference was found between dairy and beef herds concerning the zinc and copper status, although a significant higher prevalence of selenium deficiency was shown in beef herds. Further studies are needed to demonstrate the impact of the deficiencies on animals’ health and production by re-evaluating these herds after trace element supplementation. [less ▲]

Escherichia coli BL21 is a microorganism widely used in the industry for the production of recombinant proteins. The performances obtained at the laboratory level are not reproducible at a large scale. Actually, the mixing operation is not efficient enough: gradients of glucose and oxygen appear when operating in fed-batch mode. The effects of these gradients could be studied by using scale-down reactors. They make it possible to show the hydrodynamic conditions of industrial reactors. The chosen system is composed of a perfectly mixed part linked to a non-mixed one with a constant flow. Two kinds of non-mixed parts were used to induce different hydrodynamic conditions: one has a dispersed flow and the other a piston flow. The addition of the glucose is made according to the dissolved oxygen. The observed parameters are the evolution of biomass concentrations, glucose and acetate, cell viability and the production of a recombinant protein. Other parameters are calculated on the base of the fed-batch dynamics of the process. It has been proved that is possible to study the carbon starvation thanks to the recording of the dissolved oxygen. It has been decisive for the dynamic of the system. The behaviour of Escherichia coli BL21 is compared with the one of Escherichia coli K12. The acetate produced because of the excess of glucose in the non-mixed part of the system has a bigger influence on the dynamic. Moreover, the consequences of the excess of glucose have been studied on Escherichia coliBL21. These are a reduction of the maximal rate of growth and a cell damaging. A fed-batch control with equation is also proposed It permit to reduce the gradients of glucose in the non-mixed part of the system. In the second part of this work, a modelling procedure of the gradients of glucose in the reactor is developed and compared with the experimental results. [less ▲]

The revision of the geological map Aye - Marche-en-Famenne (Belgium, Wallonia, Hotton) has emphasized an important deformation structure named the Marenne Fault. This fault is clearly visible at the southeastern face of the Marenne quarry. The dating by rugose corals has allowed to define with precision the Givetian lithologic units that have been put in contact by this normal faul with a later, right-lateral strike-slip component. This fault, that may be traced over a few kilometers to the East, is probably late Hercynian, of the same type and origin as the Lamsoul Fault know to the South of Marche-en-Famenne. It seems to form part of a family of faults which are regularly observed on the south side of the Dinant Synclinorium. [less ▲]

In order to identify areas where desertification may have occurred over the last two decades, 109 stations located in three bioclimatic zones of Niger are analyzed. Time series of remote sensing data are well suited to this task. Here, we use time series of NOAA AVHRR normalized difference vegetation index (NDVI) data and rainfall data. In this study, trend analysis is used to identify areas within the biomes from 1981 to 1999 in Niger with apparent land degradation in semi-arid areas. It appears that most of Niger (82,5%) recorded increasing rainfall while only 78,9 % experienced increasing in integrated vegetation index (iNDVI). However, the combination of the two variables through the ratio iNDVI/RR shows a widespread reduction of the rain-use efficiency with highly significant trend for the stations grouped by bioclimatic area (p<10-6) during the studied period (1981-1999). These negative trends suggest a progressive diminution of the vegetation productivity as highlighted by the lowering of the iNDVI/RR ratio. This situation suggested a consistently environmental degradation and that desertification processes continued during the last two decades over most of the Sahelian belt of Niger. [less ▲]

The homogeneity of personality in patients suffering from psychogenic impotency has never been tested. In order 1. to test the homogeneity of the population and 2. to delineate putative prognostic scores, the authors have applied inverse factorial analysis to MMPI and Rorschach performed in a group of 100 patient suffering from "psychogenic impotence". The results obtained evidenced an heterogeneity in the group, subgroups may differ as far as prognostic is concerned. [less ▲]

In this study, trend analysis is used to identify areas within the biomes from 1981 to 1999 in Niger with apparent land degradation in semi-arid areas. It appears that most of Niger (98%) recorded increasing rainfall while only 76% experienced increasing maximum NDVI. However, the combination of the two variables through the ratio shows a widespread reduction of the rain-use efficiency with non significant trend for the stations located in northern Sahel (p=0.52), highly significant for those located in central Sahel (p=0.00009) and significant in southern Sahel (p=0.041). Overall, 75.3% of the sample recorded a significant reduction of the NDVIMax/RR ratio. Only one station out of four (24.7%) presented a stability of the ratio. These negative trends suggest a progressive diminution of the vegetation productivity as highlighted by the lowering of the NDVIMax/RR ratio. This situation suggest a consistently environmental degradation and that desertification processes continued during the last two decades over most of the Sahelian belt of Niger. [less ▲]
