UNLABELLED This study was done to examine the effect of asiaticoside on MCF-7 cell uptake of (99m)Tc-tetrofosmin ((99m)Tc-Tfos) and (99m)Tc-sestamibi ((99m)Tc-MIBI). METHODS The 3-(4,5-dimethylthiozol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was used to evaluate the effect of a 50% inhibitory concentration of asiaticoside on MCF-7 cell proliferation. MCF-7 cells were treated with 10,...

Introduction:Patients with the coronary slow flow phenomenon (SCF) frequently experience angina episodes. The purpose of this study was to determine efficacy of nicorandil in myocardial perfusion in patients with SCF. Methods: Twenty patients (50.85 ± 12.96 y) with SCF were studied.  We evaluate coronary slow flow according to protracted thrombolysis in m...

UNLABELLED The preparation, characterization, and first biologic evaluation in rats of a novel class of monocationic (99m)Tc heart imaging agents are reported. The complexes are represented by the general formula [(99m)Tc(N)(PNP)(L)](+), where L is the monoanionic form of a dithiocarbamate ligand of the type [R(1)(R(2))-N-C(=S)S](-), PNP is a diphosphine ligand of the type [(R(3))(2)P-(CH(2))(2...

UNLABELLED Assessment of tumor viability and necrosis of non-small cell lung cancer and detection of distant metastases are important for diagnosis, staging, monitoring the response to treatment and planning long-term management. We performed scintigraphy on patients with non-small cell lung cancer to determine the utility of three tumor targeting tracers for diagnosing primary lung cancer, for...

UNLABELLED Event rates associated with a normal or low-risk myocardial perfusion SPECT imaging study have been shown by numerous investigators to be associated with <1%/y of follow-up. Thus, the aim of this study was to evaluate the prognostic value of a normal (99m)Tc-tetrofosmin study in a geographically diverse registry of patients undergoing stress myocardial perfusion SPECT. A total of 4,7...

BACKGROUND Patients with a normal stress technetium 99m sestamibi study were shown to have a favorable outcome at intermediate-term follow-up. However, long-term survival has not been studied. The aim of this study was to evaluate the incidence and predictors of mortality and cardiac events at long-term follow-up after a normal exercise stress sestamibi study. Methods and results We studied 218...
