    Published 1996-01-01
    “…We studied the chronic effect of thyrotropin releasing hormone (TRH) in a patient with spinocerebellar degeneration by measuring cerebral metabolic rate for glucose (CMRG1c) using 2-[18F]fluoro-2-deoxy-D-glucose (18FDG) and positron emission tomography (PET). A 56-year-old female, who had suffered from progressive ataxia for 2 years, was treated by intravenous administration of 2 mg TRH for 3 weeks, and CMRG1c of the brain was measured before and after treatment. …”

    HSP70-Inducible hNIS-IRES-eGFP Reporter Imaging: Response to Heat Shock by Jiantu Che, Mikhail Doubrovin, Inna Serganova, Lyudmila Ageyeva, Tatiana Beresten, Ronald Finn, Ronald Blasberg

    Published 2007-11-01
    “…We also demonstrate that the local application of heat on RG2-pQHNIG70 xenografts can effectively induce hNIS and eGFP gene expression in vivo and that this expression can be efficiently visualized by fluorescence, scintigraphic, and micro–positron emission tomography imaging. Endogenous HSP70 protein and reporter expression was confirmed by postmortem tissue evaluations (immunoblot and immunohistochemistry). …”
