Several approaches may be suggested for prevention or treatment of senile osteoporosis. In elderly patients, an association of calcium and vitamin D supplementation has been shown to reduce nonvertebral fractures up to 40% over an 18-month period. Calcitonin, given parenterally or nasally, may prevent further bone loss and has been reported to significantly decrease vertebral and hip fractures. This hormone also possesses an important analgesic effect. Fluoride salts are the most effective way to significantly increase bone mass, mainly at the trabecular site. The optimal doses and regimens remain to be clearly established. The use of new formulations like sodium monofluorophosphate are likely to facilitate the search of the optimal therapeutic window. Bisphosphonates are potent inhibitors of bone resorption. They have been shown to significantly increase trabecular bone mass without impairment of cortical bone. Their use may be associated with a significant decrease in vertebral fractures, mainly in patients with severe osteoporosis. The new, second and third generation of bisphosphonates (tiludronate, risedronate, alendronate) look extremely promising but their widespread use will only be possible after a confirmation of the absence of a deleterious effect on bone quality (alendronate) and after demonstration of a reduction in vertebral and/or hip fractures following a prolonged use.

The application of sucrose synthase as a valuable biocatalyst for the synthesis of activated sugars and saccharides requires large amounts of enzyme. The purification of sucrose synthase starting from the 9 kg scale of rice (Oryza sativa) grains was achieved in five steps with 11.3% yield and 192-fold purification. The final sucrose synthase preparation was free of nucleotide di- and monophosphatases, but did contain 0.05% of both invertase and UDP-glucose-hydrolysing activity. It can be efficiently utilized for the synthesis of activated sugars. Its application for the synthesis of saccharides is possible taking into account that 15% UDP-glucose is hydrolysed within 15 h incubation time [less ▲]

Même quand elle est une lésion isolée, la CA est une maladie grave qui altère l'espérance de vie. Les causes de mortalité sont les complications liées à l'hypertension, la rupture spontanée au niveau des dilatations pré- et poststénotiques, au niveau des intercostales, et les anévrysmes disséquants. Le traitement chirurgical, par résection-anastomose ou interposition de greffe, introduit il y a plus de 50 ans, est obéré d'une mortalité faible chez l'adulte (1,3 %). Il ne normalise pas toutefois l'espérance de vie du patient opéré, qui reste un patient à haut risque. Les complications tardives sont proportionnelles à l'importance de l'hypertension préopératoire et à l'âge du patient au moment de l'opération. La guérison de l'hypertension est mieux assurée si le patient a été opéré dans l'enfance. Le taux de resténose est élevé pour les CA opérées avant l'âge de deux ans. Un suivi cardio-vasculaire est indispensable chez tout opéré. [less ▲]

Single-electron capture (SEC) by (NH3)2+ with rare gases (He, Ne, Ar, Kr, Xe) and benzene, (NH3)2++G->NH3++G+, has been investigated using a forward geometry double-focussing mass spectrometer. The SEC cross-section goes through a maximum within a reaction window centered at an exothermicity of approximately 4.5 eV. This corresponds to a target-projectile distance for the charge transfer of about 3.2 Angstöm. The average internal energy of NH3+-ions resulting from SEC has been obtained both via translational energy gain measurements and via an analysis of the daughter ion spectra. The agreement between both methods is satisfactory and shows that the lower the ionisation energy of the target, the more probable the excitation of NH3+ to the A2E state. With benzene (ionization energy=9.25 eV) as the target gas, however, the excess energy is converted partly to internal energy of C6H6+, leading most probably to the D2B2u, E2B1u and F2A1g states of C6H6+. A model based on the Landau-Zener non-adiabatic formalism, including one entrance channel (NH32++G) and two exit channels (NH3+ X2A"2+G+ and NH3+ A2E+G+) accounts qualitatively for the observed results in the case of exothermic single-electron capture. This model is not appropriate for slightly exothermic and endothermic charge transfer, i.e., in the present case, for the Ne and He target gases. [less ▲]
