We investigated adaptation to nitrogen narcosis by compressing 11 highly experienced divers in a hyperbaric chamber to the equivalent of 54.6 meters of seawater once a day for 5 consecutive days. The behavioral component of narcosis was assessed with a serial choice-reaction time (RT) task, and the subjective component with a global magnitude estimate.(More)
Intranasal corticosteroids are increasingly used to treat allergic rhinitis and their long-term use is generally safe. However, the long-term safety of each molecule should be assessed. The main aim of this multicenter, prospective, randomized, open-label study was to evaluate the effect of triamcinolone acetonide aqueous intranasal spray on nasal mucosal(More)
In a previous study we showed, by immunohistochemical analysis on rabbit fundic mucosa, that in addition to its usual presence on the luminal plasma membrane of endothelial cells, angiotensin converting-enzyme (ACE) was localized inside granules of surface and neck mucous cells and within granules of chief cells. The aim of the present study was to localize(More)
Below 30 m, nitrogen narcosis can severely degrade the performance of air breathing divers. Within the diving community it is generally thought that this effect can be reduced by repeating deep air dives on successive days but laboratory studies have found no strong evidence to support the notion of adaptation to narcosis. One possible explanation for this(More)
Gastrin has been shown to promote the growth of some colonic tumor cell lines. To evaluate the involvement of this hormone in the proliferation of gastric tumors, we studied the effects of gastrin/CCK-receptor antagonists (L365,260 and L364,718), proglumide and C terminal-specific gastrin antibodies on the human gastric adenocarcinoma cell line HGT-1.(More)
Angiotensin-converting enzyme (ACE) was localized by immunocytochemical methods in the rat adrenal gland. The three-layer peroxidase-antiperoxidase method was used with light and electron microscopy. At the cortical level, ACE immunoreactivity occurred only on the luminal side of vascular endothelial cell membranes in the adrenal capsule, whereas no ACE(More)
The prognosis for glioma patients is poor, and development of new treatments is critical. Previously, we engineered polymer-based vaccines that control GM-CSF, CpG-oligonucleotide, and tumor-lysate presentation to regulate immune cell trafficking and activation, which promoted potent immune responses against peripheral tumors. Here, we extend the use of(More)
We have previously shown that angiotensin I-converting enzyme (ACE) was expressed by epithelial cells of the rabbit gastric mucosa. In a search to obtain a cell model to study the regulation of ACE expression of gastric origin and its relationship with gastrin-cholecystokinin peptides, which have been proposed as ACE substrates, we investigated whether the(More)
