Calcium phosphate (CaP) has traditionally been used for the repair of bone defects because of its strong resemblance to the inorganic phase of bone matrix. Nowadays, a variety of natural or synthetic CaP-based biomaterials are produced and have been extensively used for dental and orthopaedic applications. This is justified by their biocompatibility, osteoconductivity and osteoinductivity (i.e. the intrinsic material property that initiates de novo bone formation), which are attributed to the chemical composition, surface topography, macro/microporosity and the dissolution kinetics. However, the exact molecular mechanism of action is unknown. This review paper first summarizes the most important aspects of bone biology in relation to CaP and the mechanisms of bone matrix mineralization. This is followed by the research findings on the effects of calcium (Ca(2)(+)) and phosphate (PO(4)(3)(-)) ions on the migration, proliferation and differentiation of osteoblasts during in vivo bone formation and in vitro culture conditions. Further, the rationale of using CaP for bone regeneration is explained, focusing thereby specifically on the material's osteoinductive properties. Examples of different material forms and production techniques are given, with the emphasis on the state-of-the art in fine-tuning the physicochemical properties of CaP-based biomaterials for improved bone induction and the use of CaP as a delivery system for bone morphogenetic proteins. The use of computational models to simulate the CaP-driven osteogenesis is introduced as part of a bone tissue engineering strategy in order to facilitate the understanding of cell-material interactions and to gain further insight into the design and optimization of CaP-based bone reparative units. Finally, limitations and possible solutions related to current experimental and computational techniques are discussed. [less ▲]

Based on the time-dependent Ginzburg-Landau equations, we study numerically current-driven vortices in a micrometer size square type-II superconductor. We demonstrate that the applied current significantly influences the dynamics of the vortices entering the sample. Strikingly, we find that a giant vortex can be created by the current-assisted collision of two singly quantized vortices. [less ▲]

We investigate experimentally and theoretically the vortex dynamics in a superconducting film with nanoengineered open vortex traps which provide tunable pinning, ranging from no pinning for a certain current direction to finite pinning when reversing the current flow. The design is based on the confinement of the vortex motion within two repulsive walls, one with periodic microprotrusions and the other one smooth. Clear commensurability effects are seen if the bias current drives the vortices inside the traps, whereas these effects are much less pronounced when the current pushes the vortices against the smooth surface. For small periods of the protrusions or large vortex sizes, the properties displayed by the vortices, pushed against these two surfaces of dissimilar roughness can be thought of as due to the change of effective sliding friction.

Le présent volume constitue les actes du onzième colloque de l'AiRDF, qui s’est tenu à Liège, du 26 au 28 aout 2010, et avait pour thème la question suivante : « Quelles progressions curriculaires en français ? » Poser cette question, c’était donner à entendre que les curriculums (les plans d’action) et les progressions (les étapes prévues pour réaliser ces plans) pouvaient différer sensiblement d’une institution scolaire à l’autre. Il s’agissait alors de se demander quels étaient hier et quels sont aujourd’hui les finalités de l’école et les buts de la formation disciplinaire en français. Il s’agissait de se demander si ces finalités et ces buts avaient été, jadis ou naguère, explicitement énoncés et s’ils le sont à l’heure actuelle. Il s’agissait de se demander à quel point leur énoncé et leur poursuite par l’ensemble des acteurs impliqués reflètent les tensions de notre discipline, tensions liées, d’une part, à son identité problématique, et, d’autre part, aux déterminations socioculturelles. Il s’agissait de réfléchir aussi aux implications d’une évaluation scientifique de la mise en oeuvre du curriculum et aux conditions de possibilité d’une progression curriculaire qui réduirait les tensions susdites. Poser cette question, c’était enfin inciter les chercheurs à se pencher sur la réalisation des plans d’action. Les contributions réunies dans ce volume abordent ces problèmes à propos de l’enseignement du français en France, en Suisse romande, au Québec, en Belgique francophone et au Liban, de la maternelle à la formation continuée des enseignants.

Seventeen patients with Cushing's disease (CD) were treated from 1978 to 2000. There were 11 males and 6 females aged 6.8-18.8 years (mean age 13.0 +/- 5.9 years). Presenting features were: weight gain (100%); growth failure (71%); hirsutism (53%); striae (53%); hypertension (47%). Mean age of patients with striae was 15.2 +/- 2.3 years, without striae 10.3 +/- 3.3 years. Median height SDS was -1.81 (range -0.28 to -4.17), 53% having height SDS < -1.8. The height velocity in 6 subjects was subnormal (0.9-3.8 cm/year). Median BMI SDS was 2.29 (range 1.72-5.06). Cushing's disease was confirmed by detectable serum ACTH, median 28 ng/l (range 12-99, NR <10-50) (n = 15); loss of cortisol circadian rhythm values at midnight ranging from 216 to 1,080 nmol/l (NR <50) (n = 15); lack of cortisol suppression (NV < 50 nmol/l) during low-dose dexamethasone suppression test (LDDST) (0.5 mg 6-hourly x 8) (n = 14); and >50% suppression of cortisol compared with the basal value during high-dose dexamethasone suppression test (HDDST) (2 mg 6-hourly x 8) (n = 14). A CRH test (1 microg/kg i.v.) showed an increase of cortisol from 12 to 217% (median 73.5%) (n = 16). Pituitary imaging (CT/MRI) showed an image consistent with microadenoma in 6/17 patients, but there was concordance between pituitary imaging and surgical findings in 1/11 patients (9%). Inferior petrosal sinus sampling (IPSS) for ACTH after CRH was performed in 11 subjects (age 10.7-18.8 years). Central to peripheral ACTH ratios were >2 (2.5-157.2) in 10/11 patients. The inter-petrosal sinus ACTH gradient was >1.4 in 10 patients (2.1-20.8), indicating lateralization of ACTH secretion. In 10 patients (91%), the side of the tumour on IPSS was predictive of findings at surgery. Therapy consisted of transsphenoidal microadenomectomy (TSS) in 16 patients and bilateral adrenalectomy (1978) in 1. Following TSS alone, 7 patients were cured (cortisol <50 nmol/l) and 2 were in remission (cortisol <300 nmol/l), i.e. 56%. Seven had persisting hypercortisolaemia and underwent pituitary irradiation (4,500 cGy). Therapeutic outcome for a median of 8 years (0.5-24 years) resulted in cure of CD in 14/17 patients (82%) and remission in 1. Linear growth after TSS +/- pituitary irradiation in 10 subjects showed no short-term catch-up growth, with peak growth hormone (GH) 0.5-20.9 mU/l to insulin tolerance test (ITT)/glucagon. Eight patients were treated with human growth hormone (hGH) (14 U/m(2)/week) combined in 3 with GnRH analogue. The mean final (n = 6) or latest (n = 4) height SDS was -1.36. The difference between final/latest height SDS and target height SDS was 0.93 +/- 1.13, i.e. less (p = 0.005) than the difference between height SDS and target height SDS at presentation, i.e. 1.72 +/- 1.26, indicating long-term catch-up growth.
