Oncolytic viruses show promise for treating cancer. However, to assess therapeutic efficacy and potential toxicity, a noninvasive imaging modality is needed. This study aimed to determine if insertion of the human sodium iodide symporter (hNIS) cDNA as a marker for non-invasive imaging of virotherapy alters the replication and oncolytic capability of a(More)
Positive peritoneal cytology confers the same prognosis as clinical stage IV disease in gastric cancer. Conventional cytology examination, however, has low sensitivity. We hypothesize that real-time polymerase chain reaction (RT-PCR) may have increased sensitivity and provide more accurate staging information. From February 2007 to April 2009, peritoneal(More)
INTRODUCTION Oncolytic viruses show promise for treating cancer. However, to assess therapy and potential toxicity, a noninvasive imaging modality is needed. This study aims to determine the in vivo biodistribution, and imaging and timing characteristics of a vaccinia virus, GLV-1h153, encoding the human sodium iodide symporter (hNIS. METHODS GLV-1h153(More)
BACKGROUND Reversible electroporation has long been used to transfer macromolecules into target cells in the laboratory by using an electric field to induce transient membrane permeability. Recently, the electric field has been modulated to produce permanent membrane permeability and cell death. This novel technique, irreversible electroporation (IRE), is(More)
BACKGROUND Electroporation uses an electric field to induce pores in the cell membrane that can transfer macromolecules into target cells. Modulation of electrical parameters leads to irreversible electroporation (IRE), which is being developed for tissue ablation. We sought to evaluate whether the application of IRE may induce a lesser electric field in(More)
BACKGROUND Gastroesophageal cancer remains a leading cause of cancer deaths and is uniformly fatal in patients presenting with metastases and recurrence. This study sets out to determine the effect of a third-generation, replication-competent, oncolytic herpes simplex type 1 virus containing transgenes encoding for a fusogenic membrane glycoprotein and(More)
BACKGROUND Pancreatic cancer is a fatal disease associated with resistance to conventional therapies. This study aimed to determine changes in gene expression patterns associated with infection and susceptibility of pancreatic cancer cells to an oncolyticvaccinia virus, GLV-1h153, carrying the human sodium iodide symporter for deep tissue imaging of(More)
The rate of glucose consumption and pyruvate and lactate production in red blood cells of normal, sickle cell trait and SS disease subjects were measured. Glucose consumption was found to be increased significantly (p<0.05) in red cells of sickle cell patients than the sickle cell trait and normal persons. There was also an increased rate (p<0.05) of(More)
