n the cerebellum, the parallel fiber-Purkinje cell synapse can undergo long-term synaptic plasticity suggested to underlie motor learning and resulting from variations in intracellular calcium concentration ([Ca2+]i). Ca2+ binding proteins are enriched in the cerebellum, but their role in information processing is not clear. Here, we show that mice deficient in calretinin (Cr-/-) are impaired in tests of motor coordination. An impairment in Ca2+ homeostasis in Cr-/- Purkinje cells was supported by the high Ca2+-saturation of calbindin-D28k in these cells. The firing behavior of Purkinje cells is severely affected in Cr-/- alert mice, with alterations of simple spike firing rate, complex spike duration, and simple spike pause. In contrast, in slices, transmission at parallel fiber- or climbing fiber-Purkinje cell synapses is unaltered, indicating that marked modifications of the firing behavior in vivo can be undetectable in slice. Thus, these results show that calretinin plays a major role at the network level in cerebellar physiology [less ▲]

Evidence of the existence of two forms of cyclooxygenases and the clinical relevance of COX-2 inhibition led to the development of COX-2 selective NSAIDs. In order to evaluate this selectivity, we have developed and validated an enzymatic method. The precision and reproducibility of the assay were determined and COX-2 selectivity examined using nimesulide and indometacin. [less ▲]

he aim of our work is to identify new genes and proteins involved in the control of the proliferation of thyroid cells as putative protooncogenes and antioncogenes. Several strategies are discussed. A first study has allowed to identify three new genes. Further search will use the differential display and gene arrays methodology. The role of the identified proteins coded by the genes is studied in vitro by the search of partner proteins by the double hybrid method and in vivo by mice gene knockout technology [less ▲]

This article is the result of the study of 10.000 burial certificates. It analyses the movement of corpses in an urban region which houses 510.000 peoples and tends to explain the motivation of cemetery choice. It underlines the connections between post-mortem mobility, the different levels of population mobility and culture. [less ▲]

SHIP2 is a new member of the inositol polyphosphate 5-phosphatase family showing homology to SHIP1. The structure of both enzymes is characterized by the presence of a 5' SH2 domain, a central catalytic domain, and a 3' proline-rich region. Recent results suggest that SHIP2 and SHIP1 act downstream of various receptors by removing a phosphate from the 5' position of the phosphatidylinositol 3'-kinase phosphatidylinositol 3,4, 5-triphosphate product and of inositol 1,3,4,5-tetrakisphosphate. Human SHIP2 is highly expressed in adult heart, skeletal muscle, and placenta, whereas SHIP1 expression is limited to the hematopoietic system. We report here the molecular analysis of the mouse SHIP2 cDNA and the corresponding protein, the structure of the gene, and the identification of its promoter. SHIP2 mRNA expression was analyzed in embryonic and adult mouse tissues by reverse transcription-polymerase chain reaction and in situ hybridization. In embryonic day 15.5 mice, SHIP2 was strongly expressed in the liver, specific regions of the central nervous system, the thymus, the lung, and the cartilage perichondrium. In adult mice, SHIP2 mRNA was markedly present in the brain and the thymus and at different stages of spermatozoa maturation in the seminiferous tubules. The subtle differences in the protein structure of SHIP2 and SHIP1 as well as their different patterns of expression are discussed [less ▲]

Les "Tables de cubage des arbres et des peuplements forestiers" sont destinées aux propriétaires, aux gestionnaires et aux exploitants forestiers de la Moyenne et de la Haute Belgique et des régions limitrophes (Allemagne, France et Grand-Duché de Luxembourg), ainsi qu'aux enseignants qui s'intéressent aux problèmes d'estimation et de croissance des arbres et des forêts. Elles comprennent des tables et des équations de cubage très diversifiées relatives à douze essences ou groupes d'essences : bouleaux, chênes, chêne rouge d'Amérique, douglas, épicéa, érable sycomore, frêne, hêtre, mélèzes, merisier, ormes et pin sylvestre. Les équations sont présentées sous une forme mathématique conventionnelle. Moyennant quelques modifications, celles-ci peuvent être converties en langages de programmation courants sur les micro-ordinateurs, être utilisées sur des machines à calculer programmables ou encore au sein de feuilles de calcul propres aux tableurs.
