The mechanisms by which commensal bacteria suppress inflammatory signalling in the gut are still unclear. Here, we present a cellular mechanism whereby the polarity of intestinal epithelial cells (IECs) has a major role in colonic homeostasis. TLR9 activation through apical and basolateral surface domains have distinct transcriptional responses, evident by(More)
PURPOSE OF REVIEW Since intestinal epithelium expresses Toll-like receptors, it was suggested that the intestinal epithelium is actively involved in the maintenance of colonic homeostasis. Here we describe our recent findings, which support an active contribution of colonic epithelium to intestinal homeostasis via a unique activation of epithelial TLR9. (More)
PURPOSE To re-examine the patterns of radiographic involvement in ankylosing spondylitis (AS). MATERIALS AND METHODS This prospective study had institutional review board approval, and 769 patients with AS (556 men, 213 women; mean age, 47.1 years; age range, 18-87 years) provided written informed consent. Radiographs of the cervical spine, lumbar spine,(More)
In order to evaluate the short-term lung function effects of high-pressure positive expiratory pressure (PEP)-mask physiotherapy (PT) in relation to PT-assisted sputum production, we studied 18 patients with cystic fibrosis (CF), hospitalized for a pulmonary exacerbation. Lung functions were measured before (a) and after PT (b) on day one (1), five (2), ten(More)
Primary perfluoroalkyl compounds of iridium undergo facile two-electron reduction to afford a simple route to difluorocarbene and perfluoroalkylidene complexes, two of which have been crystallographically characterized. Low-temperature protonation reactions illustrate that the thermodynamic site of protonation depends on the nature of the fluorinated(More)
