We investigated the structure of SiO2 glass up to 172 GPa using high-energy X-ray diffraction. The combination of a multichannel collimator with diamond anvil cells enabled the measurement of structural changes in silica glass with total X-ray diffraction to previously unachievable pressures. We show that SiO2 first undergoes a change in Si-O coordination number from fourfold to sixfold between...

The effectiveness of long term EEG monitoring in the localization of the epileptic focus was studied in 37 patients with temporal lobe epilepsy comprising 190 recorded seizures, in 19 frontal lobe epileptic patients with 172 recorded seizures and in 12 additional patients which were classified as fronto-temporal. In the temporal lobe group, 49/190 seizures began focally (26%) and 20/190 seizure...

Hepatitis C virus core protein is the viral nucleocapsid of hepatitis C virus. Interaction of core with cellular membranes like endoplasmic reticulum (ER) and lipid droplets (LD) appears to be involved in viral assembly. However, how these interactions with different cellular membranes are regulated is not well understood. In this study, we investigated how palmitoylation, a post-translational ...

Laccase from Pleurotus florida was immobilized on agarose/agar/polyacrylamide gel, glass beads and alginate beads. The laccase entrapped agarose gel exhibited 88% of immobilization yield as compared to laccase immobilization on glass bead (72%) and Ba-alginate (50%). The enzyme embodied in agarose gel showed greater storage stability at 16°C as compared to enzyme immobilized on glass beads and ...
