Barium examinations of the large and small bowel were analyzed in six of seven patients who had adenocarcinoma in areas of the intestine affected with Crohn disease; radiographic changes were correlated with clinical, surgical, and pathologic findings. Radiographic examinations were available in five of these patients at the time of diagnosis of tumor. Two(More)
Four ErbB receptors and multiple growth factors sharing an epidermal growth factor (EGF) motif underlie transmembrane signaling by the ErbB family in development and cancer. Unlike other ErbB proteins, ErbB-2 binds no known EGF-like ligand. To address the existence of a direct ligand for ErbB-2, we applied algorithms based on genomic and cDNA structures to(More)
Clinical and experimental data suggest that ErbB-4, a member of the epidermal growth factor receptor family, may have a role in cancer progression and response to treatment. We found recently, using a retrospective clinical analysis, that expression of ErbB-4 receptor is correlated with metastatic potential and patient survival in non-small-cell lung cancer(More)
Our knowledge on Neuregulin-1 (Nrg-1) during development of the nervous system is increasing rapidly, but little is known about Nrg-1-ErbB signaling in the adult brain. Nrg-1 is involved in determination, proliferation, differentiation, and migration of neurons and glial cells in the developing brain. In the peripheral nervous system, Nrg-1 signaling is(More)
There is an increase in the production of gallbladder stones (cholelithiasis) following gastrectomy associated with vagotomy; we hypothesized that in the presence of constant stimulation of the vagal system, there should be decreased production of gallstones. Forty-two myasthenia gravis patients taking continuous anticholinesterase medications underwent(More)
