The mechanism by which enteropathogenic Escherichia coli (EPEC) causes diarrhea remains elusive. Several alterations within the host cell have been demonstrated to occur following EPEC attachment including increases in intracellular Ca2+ concentration and rearrangement and phosphorylation of several cytoskeletal proteins. The consequences of these(More)
BACKGROUND & AIMS Infection of epithelial cells with enteropathogenic Escherichia coli (EPEC) induces phosphorylation of the 20-kilodalton myosin light chain (MLC20). The physiological consequence of this biochemical observation, however, has not been discerned. The aim of this study was to determine if EPEC-induced phosphorylation of MLC20 was involved in(More)
PURPOSE Anorectal diseases are common in human immunodeficiency virus-infected individuals. The aim of this prospective study was to assess the cause and clinical presentation of anorectal disease in this human immunodeficiency virus-infected population. METHODS A registry of all human immunodeficiency virus-seropositive patients with anorectal complaints(More)
