Purpose Neuroblastoma is a solid malignant tumor with high malignancy and risk for metastasis. The prognosis of neuroblastoma ranges from spontaneous regression to insensitivity therapies widespread There non-invasive, panoramic imaging technique called 18 F-fluorodeoxyglucose ( F-FDG) positron emission tomography–computed tomography (PET/CT), which can provide both complete anatomical informat...
The inclusion of breast cancer in this symposium on virus-associated tumors in man presumes that human breast cancer is induced by a virus or is at least strongly associated with a virus. At the moment, there appear to be 2 lines of evidence for this. The first is simply an analogy to the extensively studied mouse mammary tumor system, where a virus has been directly demonstrated. Much of the d...
BACKGROUND F18-fluorodeoxyglucose positron-emission tomography (FDG-PET) reconstruction algorithms can have substantial influence on quantitative image data used, e.g., for therapy planning or monitoring in oncology. We analyzed radial activity concentration profiles of differently reconstructed FDG-PET images to determine the influence of varying signal-to-background ratios (SBRs) on the respe...
This paper summarizes Phase I and II analysis results from NASA’s recent Mars DRA 5.0 study which re-examined mission, payload and transportation system requirements for a human Mars landing mission in the post-2030 timeframe. Nuclear thermal rocket (NTR) propulsion was again identified as the preferred in-space transportation system over chemical/aerobrake because of its higher specific impuls...
Spontaneous germinal center (GC)-derived B cell lymphomas of SJL mice (RCS) transcribe a 1.8-kb Mtv-29 mRNA under control of the META-env promoter. The encoded vSAg29 stimulates syngeneic Vbeta16(+) CD4(+) T cells, thereby acquiring T cell help necessary for RCS growth. Other strains of B cell lymphoma-prone mice include Mtv29(+) C57L and MA/MyJ, and the Mtv29(-) Mtv7(+)-recombinant inbred stra...
