This work covers homogeneous and biphasic catalysis in ionic liquids and water. The work presented herein is divided into two major parts: catalytic hydrogenation and catalytic hydroformylation. The first part also serves as an introduction to catalysis in ...
PURPOSE: To investigate the potential use of polymeric nanoparticles for the delivery of antisense oligonucleotides in HIV-1-infected cell cultures. METHODS: Phosphorothioate oligonucleotides were encapsulated into poly (D,L-lactic acid) nanoparticles. Two ...
Bone is a natural cellular composite, with a gradient structure going from a loose interconnected core to an outer dense wall, thus minimising bone weight while maintaining a high mechanical performance. Bone can be repaired using either auto- or allo- gra ...
Some models of brain energy metabolism used to interpret in vivo (13)C nuclear magnetic resonance spectroscopic data assume that intramitochondrial alpha-ketoglutarate is in rapid isotopic equilibrium with total brain glutamate, most of which is cytosolic. ...
The aim of this investigation was to test the biocompatibility of three-dimensional bioresorbable foams made of poly(L-lactic acid) (PLA), alone or filled with hydroxyapatite (HA) or beta-tricalcium phosphate (beta-TCP), with human primary osteoblasts, usi ...
TThe synthesis and properties of a novel set of building blocks for the preparation of self-assembling biomaterials are described. These molecules consist of a relatively short oligo(L-lactic acid)n segment (n̄ = 10-40) that is substituted with a cholester ...
Groundwater contamination by organochloric compounds became a major concern for public health during the last century. Chloroethenes, commonly used since the 1920's as degreasing and cleaning agents and as intermediates in chemical synthesis, accumulated i ...
Particle size should be optimized to achieve targeted and extended drug delivery to the affected tissues. We describe here the effects of the mean particle size on the pharmacokinetics and photothrombic activity of meso-tetra(carboxyphenyl)porphyrin (TCPP) ...
This report describes the synthesis and supramolecular organization of a novel class of linear-dendritic block copolymers. The molecules, which are termed rodcoil dendrons, consist of a cholesterol moiety that is attached to L-lysine dendrons of three diff ...
A total asymmetric synthesis of the polyol subunit of the polyene macrolide antibiotic RK-397 was developed through the stereoselective functionalization of (1R,1’S,6S,6’R)-3,3’-methylenebis(cyclohept-3-ene-1,6-diol). The pathway generates a large variety ...
