Methylglyoxal (MGO) is a reactive dicarbonyl metabolite of glucose, and its plasma levels are elevated in patients with diabetes. Studies have shown that MGO combines with the amino and sulphhydryl groups of proteins to form stable advanced glycation end products (AGEs), which are associated with vascular endothelial cell (EC) injury and may contribute to the progression of atherosclerosis. In ...

We report scanning tunneling spectroscopy studies of the electronic structure of 1.5–3 nm 001 textured MgO layers grown on 001 Fe. Thick MgO layers exhibit a bulklike band gap, 5–7 eV, and sparse, localized defect states with characteristics attributable to oxygen and, in some cases, Mg vacancies. Thin MgO layers exhibit an electronic structure indicative of interacting defect states forming ba...

respectively. It has been reported that coating of a thin MgO layer on SnO2 particles results in enhancement of both solar cell performance and catalytic activities. The promoting effect of MgO layer was owing to barrier effect where MgO acts as a barrier layer for charge recombination. We noticed negative shift of flatband (FB) potential of SnO2 with the increase of pH values and coating of a ...

Layered, binary thin-film oxides of NiO, MgO and CaO have been prepared and characterized using low energy electron diffraction, Auger electron spectroscopy, energy loss spectroscopy, ion scattering spectroscopy, and temperature programmed desorption using probe molecules. Epitaxial growth was observed for the NiO–MgO and CaO–NiO systems; however, superior wetting was found for NiO–MgO relative...

Porous (Zr0.5,Sr0.5)TiO3 and MgO (1, 3, 5 mol%) doped ZST nanocomposites have been developed and investigated as humidity sensing elements. The surface area analyser and FESEM data have indicated that the MgO doped perovskites are contained of the macropores and grain size of about 77 to 87 nm. EFTEM proved the reduction of particle size by addition of MgO dopant concentration. While pure ZST s...

We report our recent study on the pulsed laser deposition process in the synthesis of colossal magnetoresistive MgO/LaCaMnO3 and MgO/LaSrMnO3 core-shell nanowires. A highly efficient process has been developed by depositing an epitaxial layer of manganite onto randomly oriented MgO nanowires grown on SiO2/Si substrates. In addition, in-depth studies revealed that the sample-target distance play...

100-nm-thick Cu layers were grown on MgO(001) substrates by ultra-high vacuum magnetron sputter deposition at substrate temperatures Ts ranging from 40 to 300 °C. X-ray diffraction ω−2θ scans, ω-rocking curves, and pole figures show that layers grown at Ts=40 and 100 °C are complete single crystals with a cube-on-cube epitaxial relationship with the substrate: (001)Cu||(001)MgO with [100]Cu||[1...

Bonding of gold clusters, , 16, and 20, on MgO(100) and on thin MgO films supported on Mo(100) is investigated using first-principles density-functional theory. Enhanced adhesive bonding is found for clusters deposited on metal-supported MgO films of thickness up to about 1 nm, or 4 to 5 MgO layers, originating from electrostatic interaction between the underlying metal and metal-induced excess...

BACKGROUND Accelerated burst of polymorphonuclear leukocytes (PMNs) may be involved in the primary pathology of enhanced oxidative stress in patients with chronic kidney disease (CKD); however, the precise mechanism remains unknown. Methylglyoxal (MGO), an alpha-oxoaldehyde reportedly elevated in CKD, could induce apoptosis in several cell lines, and generates radicals by the reaction with hydr...
