BACKGROUND Expiratory rib-cage compression, a chest physiotherapy technique, is well known as the "squeezing" technique in Japan. OBJECTIVE To determine the effects of rib-cage compression on airway-secretion removal, oxygenation, and ventilation in patients receiving mechanical ventilation. SETTING An intensive care unit of an emergency and critical care center at a tertiary-care teaching ...
BACKGROUND There is very little reported in the literature about the relationship between modifications of bacterial proteins and their secretion by mammalian cells that synthesize them. We previously reported that the secretion of the bacterial enzyme Chondroitinase ABC by mammalian cells requires the strategic removal of at least three N-glycosylation sites. The aim of this study was to deter...
Secretory vesicles accumulate adjacent to the contact site between the two cells of a yeast mating pair before they fuse, but there is no direct evidence that secretion is required to complete fusion. In this study, temperature-sensitive secretion (sec(ts)) mutants were used to investigate the role of secretion in yeast cell fusion. Cell fusion arrested less than 5 minutes after inhibiting secr...
n By strict definition, antrectomy refers to removal of the gastrin-secreting portion of the stomach and when combined with a vagotomy results in an 85% reduction in gastric acid secretion. In the 1960s and 1970s, antrectomy with or without vagotomy was routinely performed for treatment of benign gastric and duodenal ulcers but, due to pharmacologic developments in reducing acid secretion and e...
A glomus vagale is a rare lesion of paraganglionic cells in the vagal perineurium. Secretion of hormones by such a tumour is exceedingly uncommon, although associated metabolic processes have been demonstrated. Clinical effects of secretion reported previously have been minimal. We report a case where resistant hypertension was eventually found to be due to a secretory glomus vagale, and was gr...
Net HCO3- transport in the rabbit kidney cortical collecting duct (CCD) is mediated by simultaneous H+ secretion and HCO3- secretion, most likely occurring in a alpha- and beta-intercalated cells (ICs), respectively. The polarity of net HCO3- transport is shifted from secretion to absorption after metabolic acidosis or acid incubation of the CCD. We investigated this adaptation by measuring net...
