Apoprotein B in fasting and postprandial human jejunal mucosa.
We tested whether apoprotein B is present in fasting and postprandial human duodenojejunal mucosa because lipoprotein-like particles are visualized by electron microscopy within the smooth endoplasmic reticulum and the Golgi cisternae of these absorptive cells. Duodenojejunal biopsies from normal volunteers were incubated in citrate buffer and were shaken in 1% EDTA so that absorptive cells cou...
متن کاملMicroflora persistence on duodenojejunal flat or normal mucosa in time after a meal in children.
A pathogenic role for high numbers of bacteria in the small intestine had been suggested previously by bacterial counts on luminal aspirates, but these investigations were flawed by the sampling device "contamination" in the mouth and the changing nature of fluent intestinal content. A procedure was developed to sterilize the Watson biopsy capsule with HCl in the upper portion of the duodenum. ...
متن کاملFixation anomaly at duodenojejunal junction.
Congenital duodenal obstruction commonly occurs due to malrotation, atresia, stenosis and annular pancreas in decreasing order of frequency. Besides this, duodenal obstruction may occur due to high fixation of duodenojejunal junction or due to hyperfixation bands at duodenojejunal flexure(l-5). We are presenting three cases in which duodenal obstruction occurred in the presence of normally rota...
متن کاملCryopreservation of Chlorophyll Synthesis and Apoprotein Stabilization in Barley Etioplasts.
Methods for the cryopreservation of protein import and integration in pea chloroplasts and of protein import or protein synthesis in tobacco mitochondria were modified to yield enzymatically active cryopreserved etioplasts from barley (Hordeum vulgare L.). The cryoprotectants ethylene glycol and dimethy sulfoxide were about 64 and 77% effective, respectively, for the cryopreservation of etiopla...
متن کاملSynthesis of phytochrome apoprotein and chromophore are not coupled obligatorily.
G Gardner and HL Gorton (1985 Plant Physiol 77: 540) demonstrated that gabaculine (5-amino-1,3-cyclohexadienylcarboxylic acid) inhibits the initial synthesis and resynthesis of spectrophotometrically detectable phytochrome in pea, maize, and oat. We show that the level of immuno-detectable phytochrome in pea is unaffected by the presence of gabaculine at a concentration that reduces spectrophot...
