Ferromagnetic properties of barium titanate ceramics doped with cobalt, iron, and nickel
The influence of annealing in strongly reducing atmosphere on the magnetic properties of hexagonal BaTiO3 + 0.04 BaO + x/2 Co2O3 (0.0025 ≤ x ≤ 0.10) ceramics was investigated. The samples air-sintered at 1673 K w...

Open AccessHuman phosphodiesterase 4D7 (PDE4D7) expression is increased in TMPRSS2-ERG-positive primary prostate cancer and independently adds to a reduced risk of post-surgical disease progression
There is an acute need to uncover biomarkers that reflect the molecular pathologies, underpinning prostate cancer progression and poor patient outcome. We have previously demonstrated that in prostate cancer c...

Next-generation sequencing reveals novel rare fusion events with functional implication in prostate cancer
Gene fusions, mainly between TMPRSS2 and ERG, are frequent early genomic rearrangements in prostate cancer (PCa). In order to discover novel genomic fusion events, we applied whole-genome paired-end sequencing to...
