BACKGROUND Plaque erosion leads to exposure of subendothelial collagen, which may be targeted by glycoprotein VI (GPVI). We aimed to detect plaque erosion using (64)Cu-labeled GPVI-Fc (fragment crystallized). METHODS AND RESULTS Four-week-old male apolipoprotein E-deficient (ApoE(-/-)) mice (n=6) were fed a high-fat diet for 12 weeks. C57BL/6J wild-type (WT) mice served as controls (n=6). Ano...

On Cu/ZrO2 catalysts, variation of the Cu loading from 0.2 wt% to 80 allows assessing influence Cu-ZrO2 interface on methanol steam reforming (MSR) performance by steering particle size and morphology, revealing contribution potential active sites at intrinsic relative contributions support surface fraction. As ZrO2 influences both CO2-selective selectivity-spoiling MSR reaction channels, disen...

The reduction of Cu(II) oxide species in siliceous matrixes of different porosity (MFI, FAU, MCM-48) and in alumosilicate MFI was studied by temperature-programmed reduction in hydrogen (TPR), by X-ray absorption fine structure (after stationary hydrogen treatments), and by transmission electron microscopy. It was found that the reduction may proceed in one or in two reduction steps. The two-st...

Although Cu and Fe are immiscible under equilibrium conditions, they can form supersaturated solid solutions by mechanical alloying. In this paper, nano-structured of the metastable Cu-Fe phase containing 10, 15, 20 and 25% wt Fe were synthesized by intensive ball milling for 15h, in order to achieve a solid solution of Fe in Cu. The phase composition, dissolution of the Fe atoms into the Cu ma...

in this paper cufe2o4, nanocrystalline powders were prepared. also, the supported cu ferrite was obtained by impregnation of the supports with cu and fe nitrates solutions, for calcination temperature 450 ºc. the samples were characterized by x-ray powder diffraction (xrd) and fourier transform-infrared spectroscopy (ft-ir). photocatalytic degradation of acid red 206 in water was studied. cufe2...

Polyethyleneimine (PEI) is known for its metal-coordinating properties and in its crosslinked form has applications in different areas ranging from drug delivery to waste water treatment and recovery of trace metals. With the aim to regulate the coordination environment of Cu(I) and Cu(II) ions in marine coatings, we have prepared a triazole cross-linking agent with 'soft' coordination that can...

The conversion of syngas (CO + H2) to gasoline-ranged hydrocarbons was carried out using a hybrid catalyst consisting of metal-loaded ZSM-5 coupled with Cu-ZnO in a near-critical n-hexane solvent. Methanol was synthesized from syngas over Cu-ZnO; subsequently, was converted to hydrocarbons through the formation of dimethyl ether (DME) over the metal-loaded ZSM-5. When 0.5 wt% Pd/ZSM-5 and 5 wt%...

Mutations in the free radical-scavenging enzyme copper/zinc superoxide dismutase (Cu/Zn-SOD) are associated with neuronal death in humans and mice. Here, we examine the effects of human wild-type (WT SOD) and mutant (Gly93 --> Ala; G93A) Cu/Zn-SOD enzyme on the fate of postnatal midbrain neurons. One-week-old cultures from transgenic mice expressing WT SOD enzyme had significantly more midbrain...

The antibacterial activity of natural zeolite (CLI) containing 2.60 wt. % Cu 2+ (Cu-CLI) or 5.07 wt.% Ag + (Ag-CLI) were tested against clinical isolates of Acinetobacter baumannii. A. baumannii belonging to the European clone I and II were isolated in Split University Hospital, Croatia. The isolate from clone II was more sensitive on the effect of the metalloaded zeolite than isolate of clone ...
