Photo-induced growth of silver nanoparticles using UV sensitivity of cellulose fibers

A simple method has been demonstrated to grow silver nanoparticles on the surface of cellulose fibers. The preparation is based on photo-activation of surface by ultraviolet (UV) photons, followed by chemical reduction of silver nitrate. It is found that t ...

Alteration of brain glycogen turnover in the conscious rat after 5h of prolonged wakefulness

Rolf Gruetter, Pierre Magistretti, Bernard Lanz, Jean-Marie Petit, Hanne Frenkel

Although glycogen (Glyc) is the main carbohydrate storage component, the role of Glyc in the brain during prolonged wakefulness is not clear. The aim of this study was to determine brain Glyc concentration ([]) and turnover time (tau) in euglycemic conscio ...

Targeted delivery and controlled release of doxorubicin to cancer cells using modified single wall carbon nanotubes

Paul Joseph Dyson, Zhaofu Fei, Xianfu Zhang

A targeted drug delivery system that is triggered by changes in pH based on single wall carbon nanotubes (SWCNTs), derivatized with carboxylate groups and coated with a polysaccharide material, can be loaded with the anticancer drug doxorubicin (DOX). The ...

Parameter and process significance in mechanistic modeling of cellulose hydrolysis

David Andrew Barry

A process-based model relevant to landfill and anaerobic digesters was developed, which included a novel approach to biomass transfer between a cellulose-bound biofilm and biomass in the bulk liquid. Model results highlighted the significance of the bacter ...

Non-invasive quantification of brain glycogen absolute concentration

Rolf Gruetter, Lijing Xin, Hongxia Lei, Ruud van Heeswijk, Hanne Frenkel, Sabrina Laus

The only currently available method to measure brain glycogen in vivo is C-13 NMR spectroscopy. Incorporation of C-13-labeled glucose (Glc) is necessary to allow glycogen measurement, but might be affected by turnover changes. Our aim was to measure glycog ...
