OBJECTIVES: The local mechanical environment influences early peri-implant tissue formation. It is still unclear whether immediate loading limits or promotes peri-implant osteogenesis and which mechanical parameters are important herein. The present study evaluated the influence of well-controlled mechanical stimuli on the tissue response around immediately loaded cylindrical turned titanium implants at two different observation periods. MATERIAL AND METHODS: A repeated sampling bone chamber, consisting of dual-structure perforated hollow cylinders with a cylindrical implant, was installed in the tibia of 14 rabbits and used to conduct three displacement-controlled immediate loading experiments: (i) 30 microm - 400 cycles/day - 1 Hz frequency - 2 x/week - 6 weeks; (ii) 30 microm - 400 cycles/day - 1 Hz - 2 x/week - 6 weeks, followed by another 6 weeks with a 50 microm - 800 cycles/day - 1 Hz - 2 x/week loading protocol; and (iii) 0 microm implant displacement for 12 weeks. A linear mixed model and logistic mixed model with alpha=5% were conducted on the data set. RESULTS: The tissue area fraction was significantly the highest after 12 weeks of loading. The bone area fraction was significantly different between all three loading conditions, with the highest values for the 12-week loading experiment. Twelve-week stimulation resulted in a significantly higher mineralized bone fraction than 6 weeks. Loading did have a significantly positive effect on the mineralized bone fraction. The incidence of osteoid-to-implant and bone-to-implant contact increased significantly when loading the implant for 12 weeks. CONCLUSION: Immediate loading had a positive effect on the tissue differentiation and bone formation around cylindrical turned titanium implants. Controlled implant micro-motion up to 50 microm had a positive effect on the bone formation at its interface. [less ▲]

Using histochemical methods the activity of acetycholinesterase, acid phosphatase and various dehydrogenases was investigated in the developing rat spinal cord. At the ninth embryonic day (E9) only the activity of the lactate dehydrogenase slow-moving isoenzymes was prominent in spinal neurons. Between E13 and E15 an increase was observed in the activity of most of the dehydrogenases and of acid phosphatase in motoneurons and posterior root ganglion cells. Between E15 and E17 acetylcholinesterase activity increased markedly. On E17 and E20, this enzyme was also detectable in anterior and posterior roots and in neurons of the intermediate grey matter. On E20, although all grey matter neurons were cytologically fully differentiated, their enzymatic content was found to be still incomplete. The prominent acid phosphatase reaction within laminae I and II, which is characteristic of the adult rat, was absent in the fetal spinal cord. These findings indicate that the spinal cord metabolism is predominantly anaerobic during the first two-thirds of gestation. The histoenzymological maturation of grey-matter neurons is delayed in comparison to their cytological differentiation. Furthermore, the ontogenesis of motoneuronal acetylcholinesterase activity correlates well with the development of motor activities in the rat fetus. [less ▲]

Ce cours d’histoire « universelle » est initialement destiné aux étudiants de l’enseignement supérieur non-universitaire (Belgique). Il tente de combler une lacune dans la mesure où il n’existe pas de manuel d’histoire destiné à ce public. Il n’est, au départ, pas conçu comme une somme d’éléments à maîtriser en fin de cycle, mais plutôt comme un horizon heuristique que l’étudiant peut parcourir afin de résoudre des problèmes historiques ou afin de construire sa vision synthétique de l’histoire humaine.

De par le rôle essentiel qu’il occupe, l’axe hypothalamo-hypophysaire, véritable chef d’orchestre du système endocrinien, constitue au niveau médical un important pourvoyeur de désordres. Il est assez paradoxal de constater que malgré l’importance de ce système, celui-ci ait été presque complètement méconnu par les physiologistes des siècles passés. En nous basant sur les conceptions physiologiques des médecins philosophes de l’antiquité puis du moyen-âge et de la renaissance nous tenterons de comprendre pourquoi le rôle de l’hypophyse a été si longtemps méconnu.
