Expression of autism spectrum and schizophrenia in patients with a 22q11.2 deletion.

Background: Copy number variants (CNVs) associated with neuropsychiatric disorders are increasingly being identified. While the initial reports were relatively specific, i.e.

Two-time window and multiangle photon correlation spectroscopy size and zeta potential analysis--highly sensitive rapid assay for dispersion stability.

Polysaccharide-stabilized iron oxide particles are highly potent contrast agents in magnetic resonance imaging. After intravenous injection, the size of these small or ultrasmall particles strongly influences their distribution in the body. Knowledge about the uniformity of particle size distribution within this particle size range is not accessible by laser diffraction (lower edge of detection range), and photon correlation spectroscopy (PCS) data only yield insufficient information, the so-called polydispersity index.

The influence of the sample preparation on plasma protein adsorption patterns on polysaccharide-stabilized iron oxide particles and N-terminal microsequencing of unknown proteins.

The in vivo organ distribution of i.v. injected drug carriers is strongly influenced by the adsorption of plasma proteins after i.

Identification of plasma proteins facilitated by enrichment on particulate surfaces: analysis by two-dimensional electrophoresis and N-terminal microsequencing.

Plasma protein adsorption on intravenously injectable drug carriers is regarded as an important factor for the fate of the particles in the body after their administration. Therefore, the plasma protein adsorption patterns on a number of different carrier systems were analyzed in vitro employing two-dimensional electrophoresis (2-DE). The particulate systems presented in this study were polystyrene (PS) model particles, PS nanoparticles surface-modified by adsorption of a surfactant, a commercial fat emulsion, and magnetic iron oxide particles used as contrast agents in magnetic resonance imaging.
