The current method of grading prostate cancer on histology uses the Gleason system, which describes five increasingly malignant stages of cancer according to qualitative analysis of tissue architecture. The Gleason grading system has been shown to suffer from inter-and intra-observer variability. In this paper we present a new method for automated and(More)
This paper uses a combined experimental and theoretical approach to gain unique insight into gene delivery. We report the synthesis and investigation of a new family of second-generation dendrons with four triamine surface ligands capable of binding to DNA, degradable aliphatic-ester dendritic scaffolds, and hydrophobic units at their focal points. Dendron(More)
Non-viral gene delivery vehicles such as polyethylenimine and polyamidoamine dendrimer effectively condense plasmid DNA, facilitate endocytosis, and deliver nucleic acid cargo to the nucleus in vitro. Better understanding of intracellular trafficking mechanisms involved in polymeric gene delivery is a prerequisite to clinical application. This study(More)
BACKGROUND Schizophrenia affects approximately 1% of subjects in all populations studied thus far. We sought to evaluate how patients with schizophrenia who are later diagnosed with breast cancer fare when adjuvant radiation therapy (ART) is clinically indicated. METHODS We searched patient treatment file, the national inpatient computer database of the(More)
