HDL Cholesterol-Associated Shifts in the Expression of Preselected Genes Reveal both Pro-Atherogenic and Atheroprotective Effects of HDL in Coronary Artery Disease.

Background: The associations of high-density lipoprotein (HDL) level and functionality with lipid metabolism, inflammation, and innate immunity in coronary artery disease (CAD) remain controversial. The differential expression of a set of genes related to HDL metabolism (24 genes) and atherogenesis (41 genes) in peripheral blood mononuclear cells (PBMC) from CAD and control patients with varied HDL cholesterol (HDL-C) levels was compared.

Methods: 76 male patients 40-60 years old with CAD diagnosed by angiography and 63 control patients were divided into three groups with low, normal (1.

Exploring and Controlling Chemistry Using Quantum Logic.

Over the past years, the development of experimental techniques for the coherent manipulation and control of isolated quantum systems has made impressive progress. Such 'quantum-logic' methods are also highly attractive in a chemical context in view of unravelling and controlling the quantum dynamics of molecular collisions and chemical reactions. Quantum technologies have the potential to transform the way chemical dynamics are investigated - by providing highly sensitive methods for state readout and spectroscopy, by opening up new pathways for the quantum-state preparation of molecules and by enabling an improved control of their microscopic behavior on the single-particle level.

Novel antibodies detect nucleocytoplasmic O-fucose in protist pathogens, cellular slime molds, and plants.

Cellular adaptations to change often involve post-translational modifications of nuclear and cytoplasmic proteins. An example found in protists and plants is the modification of serine and threonine residues of dozens to hundreds of nucleocytoplasmic proteins with a single fucose (O-Fuc). A nucleocytoplasmic O-fucosyltransferase (OFT) occurs in the pathogen , the social amoeba , and higher plants, where it is called Spy because mutants have a spindly appearance.
