UNLABELLED For noninvasive monitoring of cellular status by dual reporters, a dual membrane protein reporter system was developed and its in vivo applicability was examined. Human sodium iodide symporter (hNIS) and mutant dopamine D(2) receptor (D(2)R) transgenes were chosen considering their complementarity. METHODS pIRES-hNIS/D(2)R containing NIS and D(2)R linked with an internal ribosomal ...

Radiopharmaceuticals are radioactively labeled compounds fulfilling the requirements of pharmaceutical products, used in radio diagnosis or radiotherapy. One essential parameter in the quality control of radiopharmaceuticals is the radionuclidic purity. In this work, we present aspects regarding the radionuclidic purity determination for the radiopharmaceutical products: Sodium Iodide (I) solut...
BACKGROUND Gastric cancers have poor overall survival despite recent advancements in early detection methods, endoscopic resection techniques, and chemotherapy treatments. Vaccinia viral therapy has had promising therapeutic potential for various cancers and has a great safety profile. We investigated the therapeutic efficacy of a novel genetically-engineered vaccinia virus carrying the human s...
Tc-99m pertechnetate scintigraphy is the modality of choice for diagnosis of Meckel's diverticulum. Interpretation of Meckel's scan identifies a focal area of radiopharmaceutical uptake in the anterior abdomen similar to normal gastric mucosa. The activity must be of the same pattern and intensity as gastric uptake. We present a 13-year-old patient with gastrointest...
