Receptor tyrosine kinase activation contributes to cell viability during cytotoxic therapy. The novel broad spectrum receptor tyrosine kinase inhibitor, SU11248, inhibits vascular endothelial growth factor receptor 2, platelet-derived growth factor receptor, c-kit, and fetal liver tyrosine kinase 3. In this study, we maintained SU11248 plasma levels beyond(More)
The vascular endothelium plays a critical role in the response of cancer to ionizing radiation. Activation of the phosphoinositide-3-kinase/Akt pathway is one initial signaling event in irradiated endothelial cells. Specifically, a low dose of ionizing radiation (3 Gy) induces phosphorylation of Akt at Ser473 in the vascular endothelium within minutes of(More)
Growth factor enhancement of endothelial cell viability occurs through phosphatidylinositol 3-kinase (PI3K)/Akt-mediated inhibition of apoptosis. The PI3K/Akt signal transduction pathway was activated by both vascular endothelial growth factor and ionizing radiation. Radiation- and vascular endothelial growth factor-induced phosphorylation of Akt was(More)

In this paper, an efficient two-dimensional finite element model for a mooring cable and seabed interaction is built while geometric shape and tensions of the cable are computed in time domain. In the model, a hybrid beam element is employed to simulate the mooring cable with the seabed simulated by different soil constitutive models. When the elastic and(More)
