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 ▲]

Because of the PK-Weir geometric specificities, its hydraulic capacity remains difficult to predict without using experimental techniques. A 1D numerical model of the flow over a PK-Weir has been developed at the Research unit HACH at the University of Liege. It is based on a 1D modeling of the inlet and the outlet separately, with a single upstream reservoir and interactions between both flows by exchange of mass and momentum along the lateral crest. The comparison of the numerical results with various experimental data showed the ability of the numerical model to predict with reasonable accuracy the release capacity of a PK-Weir, whatever its geometry. The tests of the solver enable to highlight the significant influence of the inlet and outlet width on the weir release capacity. They also suggest that improvements of the numerical model may lie in the evaluation of the discharge coefficient of the lateral crest. [less ▲]

La diffraction constitue de nos jours un phénomène physique incontournable pour la recherche (diffraction par rayons X, diffraction de neutrons, cristallographie, ...) et est, à juste titre, enseignée aussi bien en dernière année de secondaire qu'à l'université. Le logiciel présenté ci-dessous est un programme permettant de réaliser des figures de diffractions de manière simple et intuitive. Il existe naturellement déjà de nombreux programmes de simulations de figures de diffractions que l'on peut facilement trouver sur internet. Cependant ceux-ci sont, pour la plupart, ou bien limités (à la connaissance de l'auteur) à quelques cas particuliers - diffractions sur une ou plusieurs fentes, un rond, plus rarement un carré - ou bien complexes à l'utilisation. Bien que ces programmes soient dignes d'intérêts et peuvent se montrer utiles dans le cadre d'un enseignement, leurs limitations empêchent d'acquérir une intuition réelle de ce qu'est la diffraction. Par exemple, quelle est la figure de diffraction obtenue par un réseau cristallin cubique, un réseau hexagonal, ou encore une hélice ? C'est précisément cette faille pédagogique que vient combler le logiciel présenté ci-dessous. En effet, celui-ci permet d'obtenir la figure de diffraction de « n'importe quelle forme » (en deux dimensions), « forme » entièrement paramétrable par l'utilisateur au moyen d'un simple fichier bitmap ; format de fichier graphique le plus répandu et le plus simple à employer. Il est naturellement également possible d'effectuer de la diffraction de manière expérimentale au moyen d'un simple laser hélium-néon (facilement accessible dans le commerce et d'un prix modéré) et de diapositives. Cependant, outre que le logiciel présenté ci-dessous peut-être obtenu gratuitement par simple demande à l'auteur, celui-ci se montre beaucoup plus souple d'utilisation que de simples diapositives car entièrement paramétrable, et, comme tout logiciel, échappe aux aléas expérimentaux (poussières sur les diapositives, problèmes d'alignements diapositives-laser, nécessité d'un local sombre, ...)

The Banzhaf power index was introduced in cooperative game theory to measure the real power of players in a game. The Banzhaf interaction index was then proposed to measure the interaction degree inside coalitions of players. It was shown that the power and interaction indexes can be obtained as solutions of a standard least squares approximation problem for pseudo-Boolean functions. Considering certain weighted versions of this approximation problem, we define a class of weighted interaction indexes that generalize the Banzhaf interaction index. We show that these indexes define a subclass of the family of probabilistic interaction indexes and study their most important properties. Finally, we give an interpretation of the Banzhaf and Shapley interaction indexes as centers of mass of this subclass of interaction indexes. [less ▲]

Myeloperoxidase (MPO) is a protein of interest due to its involvement in equine pathologies. Until now, results in equine diagnostic research were achieved through extracellular MPO detection. However, studying the cellular MPO content in neutrophils has revealed important insights in human diseases. This study aimed to develop a technique for the specific detection of MPO on the single cell level defining a flow cytometric protocol for the detection of both equine surface-bound and cellular MPO. Both indirect and direct labeling techniques are described which include the comparison of two secondary antibodies and two linking-fluorochromes, respectively. [less ▲]

The clinical hallmarks of Parkinson’s disease (PD) are movement poverty and slowness (i.e. bradykinesia), muscle rigidity, limb tremor or gait disturbances. Parkinson’s gait include slowness, shuffling, short steps, freezing of gait (FoG) and/or asymmetries in gait. There are currently no validated clinical instruments or device that allow a full characterization of gait disturbances in PD. As a step towards this goal, a four accelerometer-based system is proposed to increase the number of parameters that can be extracted to characterize parkinsonian gait disturbances such as FoG or gait asymmetries. After developing the hardware, an algorithm has been developed, that automatically epoched the signals on a stride-by-stride basis and quantified, among others, the gait velocity, the stride time,the stance and swing phases, the single and double support phases or the maximum acceleration at toe-off, as validated by visual inspection of video recordings during the task. The results obtained in a PD patient and an healthy volunteer are presented. The FoG detection will be improved using time-frequency analysis and the system is about to be validated with a state-of-the-art 3D movement analysis system. [less ▲]

Early detection of colorectal cancer or advanced adenomas is a public health priority in many industrialized countries. There are various methods of screening average risk individuals for colorectal cancer, and their effectiveness may depend on subjective parameters like local expertise and patient's preferences. This paper reviews these tests with special emphasis regarding imaging techniques that aim to provide less-invasive alternatives to optical colonoscopy (OC) which is the standard of reference. Both Double-Contrast Barium Enema (DCBE) and Virtual Colonoscopy (VC) have >90% sensitivity compared to OC in the detection of clinically relevant colonic lesions. Nevertheless, VC may have an edge over DCBE for technical and reproductivity reasons, as well as greater learning opportunities. Imaging techniques criticisms regarding diminutive and flat lesions, cost, radiation exposure and effects on gastroenterological practice are addressed. [less ▲]
