Regulation of intestinal motility depends on an intact synaptic vesicle apparatus. Thus, we investigated the expression of the synaptic vesicle markers synaptophysin and synaptobrevin in the human enteric nervous system (ENS) and their regulation by glial cell line-derived neurotrophic factor (GDNF) in cultured enteric neurons. Full-thickness specimens of(More)
Control of intestinal motility requires an intact enteric neurotransmission. Synaptosomal-associated protein 25 (SNAP-25) is an essential component of the synaptic vesicle fusion machinery. The aim of the study was to investigate the localization and expression of SNAP-25 in the human intestine and cultured enteric neurons and to assess its regulation by(More)
Staphylococcus saprophyticus surface-associated protein (Ssp) was the first surface protein described for this organism. Ssp-positive strains display a fuzzy layer of surface-associated material in electron micrographs, whereas Ssp-negative strains appear to be smooth. The physiologic function of Ssp, however, has remained elusive. To clone the associated(More)
BACKGROUND Ventilation using low tidal volumes with permission of hypercapnia is recommended to protect the lung in acute respiratory distress syndrome. However, the most lung protective tidal volume in association with hypercapnia is unknown. The aim of this study was to assess the effects of different tidal volumes with associated hypercapnia on lung(More)
BACKGROUND Primary ciliary dyskinesia (PCD) is a rare genetically induced disorder of cilia inducing mainly respiratory diseases. Transmission electron microscopy (TEM) analysis of ciliary ultrastructure is classically used for diagnosis. We report our experience of TEM investigations in a large series of patients. METHODS TEM analysis performed of 742(More)
BACKGROUND Several concepts of treatment in neonatal ARDS have been proposed in the last years. The present study compared the effects of open lung concept positive pressure ventilation (PPVOLC) with a conventional ventilation strategy combined with administration of two different surfactant preparations on lung function and surfactant homoeostasis.

BACKGROUND & AIMS In the central nervous system (CNS), reelin coordinates migration and lamination of neurons and regulates synaptic plasticity, whereas its role in the enteric nervous system (ENS) remains enigmatic. Thus we determined the expression pattern and localization of reelin in the human ENS and monitored the time course of mRNA expression of the(More)
BACKGROUND Glial cell line-derived neurotrophic factor (GDNF) is a potent neurotrophic factor known to promote the survival and maintenance of neurons not only in the developing but also in the adult enteric nervous system. As diverticular disease (DD) is associated with reduced myenteric neurons, alterations of the GDNF system were studied in asymptomatic(More)
BACKGROUND Permissive hypercapnia has been shown to reduce lung injury in subjects with surfactant deficiency. Experimental studies suggest that hypercapnic acidosis by itself rather than decreased tidal volume may be a key protective factor. OBJECTIVES To study the differential effects of a lung protective ventilatory strategy or hypercapnic acidosis on(More)
Mice lacking dynein arms in the cilia were examined; the strain was obtained by inactivation of dynein heavy chain gene in chromosome 7. The cilia of these mice were examined by electron microscopy and compared to the cilia of random-bred mice. No statistically significant differences or typical disorders in the outer or inner dynein arms were detected. The(More)
