La crise financière mondiale qui a éclaté en 2008 et les effets désastreux qu’elle a occasionnés sur le secteur minier en RDC (qui avait été placé au centre des politiques de croissance et de lutte contre la pauvreté) posent avec encore plus d’acuité la question de la diversification de la structure économique dans une province comme le Katanga. Au problème de la vulnérabilité d’un tel modèle de croissance s’ajoute le constat qui est fait dans cette étude du manque d’effet d’entrainement de l’activité des grands groupes miniers sur le reste de l’économie locale, en termes de développement des capacités productives et de création d’emplois.

Metastases formation is a complex process involving genetic and epigenetic modifications leading to several molecular pathway dysfunctions and alterations in the production and fonction of a panel of molecular mediators. Recent studies have shed light on the importance of multiple interactions occuring between tumor cells and host cells involved in the elaboration of a microenvironment permissive for tumor cell survival and growth. These tumor-host interactions are decisive, not only in the primary tumor, but also in secondary sites colonized by tumor cells. Cancer appears more and more as a sytemic disease in which tumor cell is one of the pawn in the game. System of defense are rapidly overwhelmed and tumor cells hijack host cells to promote their dissemination that likely occurs at earlier stages than initially anticipated. In the present review, we describe the novel concepts of metastases formation based on recent transcriptomic analyses and new insights acquired on the tumor microenvironment in the primary tumor and in secondary foci.

Subjective evaluation of the voice by the patient is routinely assessed in the adult dysphonic population; this Q6 is, however, not the case in the pediatric population. There were three objectives of this study: the first goal was to study the ability of children aged 5–13 years to express themselves about physical, emotional, and sociofunctional aspects of their voice. The second goal was to explore if specific voice-related complaints were expressed by dysphonic children as compared with normophonic children. The third goal was to compare the dysphonic children’s voice-related complaints with those of their mothers. The overall objective was to set the grounds for the elaboration of a standardized questionnaire in French concerning subjective evaluation of voice in children. Twenty-five dysphonic children with vocal complaint (15 nodules, one polyp, one microweb, eight unspecified) and 55 normophonic children aged 5–13 years were interviewed. The interviews were semistructured based on a canvas of voice-related questions. The dysphonic children’s mothers were interviewed with the mean of a written questionnaire and were invited to discuss their answers orally with the examiner. The results were analyzed ualitatively and statistically.AChi-square test and the Fisher’s test were used to analyze the differences between the complaints expressed by the dysphonic and the normophonic children, and a binomial test was used to compare the children’s answers with their mothers’ answers. The qualitative analysis of the interviews suggests that children are capable of reflecting over their ownvoice and of giving autonomous information about different aspects of their voice. It also appeared that voice is a complex phenomenon and that it needs to be clearly and cautiously defined to the children.We identified 27 different complaints related to the voice, out of which 17 were significantly more expressed by dysphonic than by normophonic children (P < 0.05). Three of the 27 identified complaints show significant discordances between the mothers and the dysphonic children. The results suggest that children are capable of making a subjective and autonomous evaluation of their voice and that dysphonic children experience significantly more voicerelated discomfort than nondysphonic children. The complaints expressed by the dysphonic children and their mothers are not all in concordance. The main conclusion is that a standardized subjective evaluation of the voice, not only by the parents but also by the child itself, would be relevant in the assessment of pediatric dysphonia.

The efficacy of grafting materials for alveolar bone regeneration procedures has been repeatedly corroborated by clinical and scientific evidence. Although an ever growing number of biomaterials are available on the market, the origins, material characteristics, bioactivity and osteoconductive properties of these products are not always known by clinicians, hence often hampering an adequate product selection. The purpose of this contribution was to provide an overview of five different types of osteoconductive grafting materials frequently used in dentistry (Bio-Oss®, Cerasorb M™, Bone Ceramic®, Natix®, Genos®) and to summarize their physico-chemical and morphological characteristics at the macro- and micro-scale. Furthermore, the influence of these properties on the in vivo behaviour of these biomaterials is discussed. The results of this study are presented as data sheets, which may prove helpful for clinicians in the design of their treatment strategies. [less ▲]

We study the maximum weighted independent-set problem on interval graphs with uncertainty on the vertex weights. We use the absolute robustness criterion and the min-max regret criterion to evaluate solutions. For a discrete scenario set, we nd that the problem is NP-hard for each of the robustness criteria; we also provide pseudo-polynomial time algorithms when there is a constant number of scenarios and show that the problem is strongly NP-hard when the set of scenarios is unbounded. When the scenario set is a Cartesian product, we prove that the problem is equivalent to a maximum weighted independent-set problem on the same interval graph but without uncertainty for the rst objective function and that the scenario set can be reduced for the second objective function.

OBJECTIVES: Framework design is reported to influence chipping in zirconia-based restorations, which is an important cause of failure of such restorations. Residual stress profile in the veneering ceramic after the manufacturing process is an important predictive factor of the mechanical behavior of the material. The objective of this study is to investigate the influence of framework thickness on the stress profile measured in zirconia-based structures. METHODS: The stress profile was measured with the hole-drilling method in bilayered disc samples of 20mm diameter with a 1.5mm thick veneering ceramic layer. Six different framework thicknesses from 0.5mm to 3mm were studied. Two different cooling procedures were also investigated. RESULTS: Compressive stresses were observed in the surface, and tensile stresses in the depth of most of the samples. The slow cooling procedure was found to promote the development of interior tensile stresses, except for the sample with a 3mm thick framework. With the tempering procedure, samples with a 1.5mm thick framework exhibited the most favorable stress profile, while thicker and thinner frameworks exhibited respectively in surface or interior tensile stresses. Significance: The measurements performed highlight the importance of framework thickness, which determine the nature of stresses and can explain clinical failures encountered, especially with thin frameworks. The adequate ratio between veneering ceramic and zirconia is hard to define, restricting the range of indications of zirconia-based restorations until a better understanding of such a delicate veneering process is achieved.
