Hepatoblastomas are the most frequent malignant liver tumors of childhood. A high frequency of activating beta-catenin mutations in hepatoblastomas indicates that the Wnt signaling pathway plays an important role in the development of this embryonic neoplasm. Stabilization of beta-catenin leads to an increased formation of nuclear beta-catenin-T-cell factor complexes and altered expression of W...
We collect multi-wavelength measurements of the nuclear emission of 20 low luminosity FR I radio-galaxies to test the viability of the FR I-BL Lac unifying model. Although poorly sampled, the Spectral Energy Distributions (SED) of FR Is are consistent with the double peaked shape characteristic of BL Lacs. Furthermore while the distribution of the FR Is in the broad-band spectral index planes s...
The direct conversion of biomass-derived 1,3-dihydroxyacetone (DHA) and formaldehyde to α-hydroxy-γ-butyrolactone (HBL) was achieved through the use of tin(iv) chloride and a small amount of water and the yield reached up to 70%. The reaction mechanism was also investigated by incorporating d2-formaldehyde into the reaction mixtures.
