Molecular Oncology, EarlyView.Meta‐transcriptome analysis identified FGF19 as a peptide enteroendocrine hormone associated with colorectal cancer prognosis. In vivo xenograft models showed release of FGF19 into the blood at levels that correlated with tumor volumes. Tumoral‐FGF19 altered murine liver metabolism through FGFR4, thereby reducing bile acid synthesis and increasing ...

Electronics Letters, 2010 Surface acoustic wave resonators for wireless battery-free sensing in harsh environments are under development by researchers at the University of Maine in the US. Their system, which uses frequency multiplexing for multiple-access, is designed for long term operation up to at least 900°C and could find significant application in space exploration, the
