Non-invasive methods for monitoring of the therapeutic ion beam extension in the patient are desired in order to handle deteriorations of the dose distribution related to changes of the patient geometry. In carbon ion radiotherapy, secondary light ions represent one of potential sources of information about the dose distribution in the irradiated target. The capability to detect range-changing inhomogeneities...
Klinisches/methodisches Problem Die Magnetresonanztomographie (MRT) zeichnet sich durch einen überlegenen Gewebekontrast aus, während sie nichtinvasiv und frei von ionisierender Strahlung ist. Sie bietet Zugang zu Gewebe- und Organfunktion. Eine dieser funktionellen bildgebenden Verfahren ist die Perfusionsbildgebung. Mit dieser Technik können u. a. Gewebeperfusion und Kapillarpermeabilität aus dynamischen...
p53 is a multifunctional protein and its activity can be modulated by phosphorylation and dephosphorylation. In this study, we sought to examine the notion that serine/threonine phosphatases (PP-1 and PP-2A) are active modulators of the p53-dependent apoptotic pathway. Exposure of neonatal rat cardiomyocytes to the established apoptotic agents, bafilomycin A1 (BAF) or staurosporine (STAU) induced...
