AIMS Compelling evidence from cell culture studies implicates cadherins in the neoplastic progression of melanocytic tumours but few reports describe the expression of cadherins and the related transmembrane proteins, catenins, in a full range of benign and malignant excised melanocytic tumours. METHODS Using immunohistochemistry and western blotting after tissue fractionation, the pattern of...
AIMS E-cadherin, the main epithelial intercellular adhesion molecule, is abnormally expressed in many cancer types, including gastric carcinoma, which is the second leading cause of cancer death worldwide. The aim of this study was to contribute to the characterisation of gastric carcinoma histotypes based on a new approach to E-cadherin immunoexpression. METHODS 97 gastric tumour samples obt...
Vesicles and/or other membranous structures that form after axolemmal damage have recently been shown to repair (seal) the axolemma of various nerve axons. To determine the origin of such membranous structures, (1) we internally dialyzed isolated intact squid giant axons (GAs) and showed that elevation of intracellular Ca2+ >100 microM produced membranous structures similar to those in axons tr...
INTRODUCTION Congenital jejunal stenosis and gastric duplication cysts are very rare congenital anomalies of the gastrointestinal tract in the newborn. We present a case of congenital membranous jejunal stenosis associated with gastric duplication cysts, which was diagnosed by ultrasonography. To the best of our knowledge, this is the first report of ultrasonographic diagnosis of congenital mem...
Membranous glomerulonephritis can occur as a rare paraneoplastic complication of human cancers. In this case report, we describe a patient who presented acutely with symptoms of the nephrotic syndrome including heavy proteinuria and anasarca. He was subsequently diagnosed with membranous glomerulonephritis, and soon afterwards was found to have stage IIIB non-small cell lung cancer. Following c...
