PURPOSE The cellular targeting and tumor imaging properties of a novel ErbB-2-avid peptide, discovered from bacteriophage display, were evaluated in human breast carcinoma cells and in breast carcinoma-xenografted mice. EXPERIMENTAL DESIGN The affinity of the ErbB-2 targeting peptide KCCYSL and its alanine substituted counterparts for the extracellular(More)
UNLABELLED Galectin-3 is a member of the galectin family of beta-galactoside-binding animal lectins. Galectin-3 is overexpressed in a wide range of neoplasms and is associated with tumor growth and metastases. Given this fact, radiolabeled galectin-3-targeting molecules may be useful for the noninvasive imaging of tumors expressing galectin-3, as well as(More)
Aberrant expression of ErbB-2, a member of the epidermal growth factor family of receptors, has been implicated in the formation of various malignancies including ovarian cancer. The objective of this study was to determine if the bacteriophage (phage) display-selected ErbB-2 targeting peptide, KCCYSL, once radiolabeled with (111)In would serve as a tumor(More)
INTRODUCTION Galectin-3 (gal-3) is a carbohydrate binding protein that has been implicated in cell adhesion, tumor invasion and metastasis. The objective of this study was to evaluate the tumor targeting and imaging properties of a gal-3 binding peptide selected by phage display in a mouse model of metastatic human prostate carcinoma expressing gal-3.

Fetal microchimerism (FMC) has been described to have a range of effects on health and disease. Y-chromosomal DNA has been detected in Golden Retrievers suggesting persistent FMC. In that report, nine dogs had evidence of microchimerism without prior pregnancy. To further understand this finding, a dam with prior male live births giving birth to her fourth(More)
Animal behavioral models are crucial for neurobiological research, allowing for the thorough investigation of brain pathogenesis to be performed. In both animals and humans, anxiety has long been linked to vestibular disorders. However, although there are many tests of anxiety and vestibular deficits, there are few protocols that address the interplay(More)
BACKGROUND Long-term studies have indicated that the clinical success of high tibial osteotomy deteriorates with time. The purpose of this study was to evaluate the long-term results of a combined lateral closing and medial opening-wedge technique for high tibial osteotomy with a minimum follow-up of fifteen years. METHODS From January 1981 to June 1990,(More)
Fetal microchimerism has been suggested to play contradictory roles in women's health, with factors including age of the recipient, time elapsed since microchimerism occurred, and microchimeric cell type modulating disease. Both beneficial and harmful effects have been identified in wound healing and tissue regeneration, immune mediated disease, and cancer.(More)
PURPOSE Novel biomarkers would facilitate early and accurate diagnosis of breast cancer. The Thomsen-Freidenreich (TF) and Tn antigens are aberrantly glycosylated carbohydrate cancer-associated antigens found in approximately 80% of adenocarcinomas. Both TF and Tn are expressed on cell-surface glycoproteins and glycolipids. Nipple aspirate fluid (NAF) is(More)
BACKGROUND The goal of this prospective study was to determine (a) concentrations of the carbohydrate biomarkers Thomsen Friedenreich (TF) antigen and its precursor, Tn antigen, in nipple discharge (ND) collected from women requiring biopsy because of a suspicious breast lesion; and (b) if concentration levels predicted pathologic diagnosis. METHODS Adult(More)
