Efficient hydrolytic cleavage of phosphodiester with a lanthanide-based metal-organic framework

Article abstract of DOI:10.1016/j.jssc.2020.121820

Hydrolysis of phosphate diesters has attracted substantial research efforts, not only in bio-organic chemistry, but also in inorganic chemistry. Herein, a lanthanide-based metal-organic framework was synthesized by incorporating a tetraphenylethylene moiety as the four-point connected node, Ce-TCPE (noted as 1). The structural analyses indicate that 1 exhibits 3D framework connected by the sharing carboxylate groups with two kinds of 1D rhombic channels when viewed along the c direction. Hydrolytic cleavage catalysis have been performed and showed that 1 could act as efficient heterogeneous catalyst for the hydrolytic cleavage of the phosphodiester BNPP (bis(p-nitrophenyl)phosphate) with the high activity and hydrolytic stability in a pseudo-first-order rate. DFT studies has also gain an insight analysis to elucidate the cleavage process.

La prise en charge reeducative du membre superieur evolue
` `
grandement en 2013 a la lumiere des travaux de recherche
Based on current research in this field, rehabilitation care
of the upper limbs has greatly evolved in 2013. We chose to
devote this second pediatric session to two upper limb
pathologies frequent in PMR: obstetric brachial plexus palsy
(OBPP) and hemiplegia type cerebral palsy (CP). After a focus
on current knowledge and practices in OBPP, we will examine
the biomechanical consequences of these injuries on muscu-
loskeletal growth. Recalling the last SFERHE congress on
upper limb rehabilitation in CP children and adults, we will
discuss the contribution of mental imaging as part of this
rehabilitation process. We will also present a protocol using an
interactive robot.

Nous avons donc fait le choix de consacrer cette deuxieme

frequentes en MPR a savoir la paralysie obstetricale du plexus
