The phenotypic heterogeneity of low-grade gliomas (LGGs) is still inconsistently explained by known molecular abnormalities in patients treated according to the present standards of care. IDH1 codon 132 and IDH2 codon 172 sequencing was performed in a series of 47 LGGs and correlated with clinical presentation, MR imaging characteristics, genomic profile(More)
The mechanism for phonon scattering by nanostructures and by point defects in nanostructured silicon (Si) and the silicon germanium (Ge) alloy and their thermoelectric properties are investigated. We found that the thermal conductivity is reduced by a factor of 10 in nanostructured Si in comparison with bulk crystalline Si. However, nanosize interfaces are(More)

A new phloroglucinol diglycoside 1, together with eight known compounds, were isolated from Hypericum japonicum Thunb. The structure of the new compound 1 was determined by spectroscopic methods to be 4,6-dimethyl-5-O-[alpha-L-rhamnopyranosyl-(1-->6)-alpha-D-glucopyranosyl] multifidol. Different solvent extracts of Hypericum japonicum Thunb. were tested for(More)
