Extensive studies that have been conducted on the Pb(Mg1/3Nb2/3)O3 (PMN) family of relaxor ferroelectrics have led to the establishment and acceptance of the ‘‘spacecharge’’ model as a basis for explaining their structures and dielectric properties. In this model, the arrangement of the metal cations on the octahedral sites of the perovskite structure is interpreted in terms of the formation of...

Copper substitution together with nano-structuring are applied the aim to increase bactericidal performances of rocksalt-type MgO oxide. The partial magnesium ions Cu2+ has been successfully achieved in both micrometer- and nanometer-sized particles up 20 mol% increments 5 mol%. Microstructural analyses using Integral Breadth method revealed that thermal decomposition single source precursor Mg...

La maladie de Gaucher de type 1 (MG1) est une maladie multisystémique rare due à un déficit génétique en bêtaglucocérébrosidase lysosomale. Ses signes cliniques sont très polymorphes: splénomégalie (95%), hépatomégalie (80%), cytopénies (thrombopénie, anémie, neutropénie)... L'atteinte ostéoarticulaire est une complication majeure qui se voit dans 70 à 100% des cas selon les séries. Les anomali...

Alternaria sp. MG1, an endophytic fungus previously isolated from Merlot grape, produces resveratrol from glucose, showing similar metabolic flux to the phenylpropanoid biosynthesis pathway, currently found solely in plants. In order to identify the resveratrol biosynthesis pathway in this strain at the gene level, de novo transcriptome sequencing was conducted using Illumina paired-end sequenc...
