On the High Sensitivity of the Electronic States of 1 nm Gold Particles to Pretreatments and Modifiers.

In this paper, the effect of modifiers and pretreatments on the electronic states of 1 nm gold nanoparticles (AuNPs) supported on silica was systematically studied. AuNPs deposited on silica (particle size of 2-4 nm) modified with Ce, La and Fe oxides, were studied by FTIR of adsorbed CO after different redox treatments at 100, 300 and 500 °C. This study was conducted at room temperature to allow detecting the electronic states of gold, which is more likely involved in CO oxidation at the same temperature.

Effect of the herbal combination Canephron N on diabetic nephropathy in patients with diabetes mellitus: results of a comparative cohort study.

Objectives: Diabetic nephropathy (DN) is a serious and common complication of diabetes mellitus leading to end-stage renal disease in up to 30% of diabetic patients. The first manifestation of DN in humans is microalbuminuria, which arises from the increased passage of albumin through the glomerular filtration barrier. Reactive oxygen species, inflammatory cytokines, and growth factors are key players in the context of damage to the glomerular filtration barrier.
