The Mechanism of the Reduction of Acid by the Normal Human Duodenum
The story of the function of the duodenum has not been completely told because it is not entirely known. The entire tube of the small intestine, whose mucous membrane has the power to alter food substances chemically and transform them into a product which is capable of absorption into the blood …

Sexing Study of Interphase Duodenum and Liver Nuclei in the Sixteen-Day Chick Embryo
A study was made to confirm the existence of sex chromatin or some other sexual dimorphism in the interphase nuclei of the 16-day chick embryo. A Feulgen staining procedure was performed on sectioned epithelial tissues of the intestinal villi as well as sections and squashes of liver tissues. All …

The cystic fibrosis transmembrane conductance regulator and acid-base transporters of the murine duodenum
The alkaline mucus barrier of the duodenum plays an important role in protecting the epithelium from acidic chyme entering from the stomach. Active HCO₃⁻ secretion involves the apical membrane activities of the cystic fibrosis transmembrane conductance regulator (CFTR) Cl⁻ channel, the protein that …

Investigation of splanchnic perfusion utilising an intraluminal opto-electronic sensor placed in the duodenum
… of photoplethysmography intraluminally in the duodenum in order to measure the haemodynamic changes occurring in the splanchnic circulation in a minimally invasive fashion. A bespoke processing system and data acquisition virtual instrument were designed and developed to allow continuous and …

Transkriptionelle Regulation des Homeo-Domänen-Transkriptionsfaktors Islet/Duodenum Homeobox-1 (IDX-1) in insulinproduzierenden Betazellen des endokrinen Pankreas
Die Betazellmasse wird durch Apoptose, Proliferation und Neogenese aus Vorläuferzellen an den Bedarf des Organismus angepasst. Fehlregulationen und Verlust der Anpassungsfähigkeit sind Ursachen für Diabetes mellitus Typ-2. IDX-1 ist sowohl ein Hauptentwicklungsfaktor des embryonalen Pankreas als …

Comparison of Motility between the Sphincter of Oddi and the Duodenum in Percutaneous Transhepatic Manometry of the Sphincter of Oddi
"배경 및 목적: 동물실험에서 Oddi 괄약근 운동성이 시간의 경과에 따라 주기적인 변화를 보이며, 이러한 주기적인 변화가 소장의 migrating motor complex (MMC)의 주기와 밀접한 연관성이 있다고 보고된 바 있다. 본 연구는 인체에서 경피적 경로를 통한 장기간의 Oddi 괄약근 내압 검사를 시행함으로써 Oddi 괄약근의 주기적 운동성을 포함하는 전체적인 운동성에 대해 살펴봄과 동시에 Oddi 괄약근의 주기적 운동성을 MMC의 각 단계로 나누어 보고, 십이지장의 MMC와의 관련성에 대해서도 알아보고자 하였다. …

Regulation of Intestinal Development and Function in Early-Life Pigs
… epithelial development by analyzing the duodenum, jejunum, and ileum of 70 pigs sampled at 0, 7, 20, 22, 25, and 28 days of age (n=10 pigs/day). Frozen tissues were assessed for brush border activity and found shifts in enzymatic activity coinciding with luminal content changes. Formalin- …

Tissue- and Development-specific Expression of Proton-mediated Peptide Transporters in the Developing Chicken
… and PHT1 mRNA expression in the proventriculus, duodenum, jejunum, ileum, ceca, large intestine, brain, heart, bursa of Fabricius, lung, kidney, and liver in layer chicks on embryonic days 18 and 20 and days 1, 3, 7, 10, and 14 post-hatch. Absolute quantification real-time PCR was used to measure …

Expression of Digestive Enzymes and Nutrient Transporters in the Intestine of Eimeria-challenged Chickens
… is site specific. Eimeria acervulina infects the duodenum, E. maxima the jejunum, and E. tenella the ceca. Lesions in the intestinal mucosa cause reduced feed efficiency and body weight gain in Eimeria-challenged chickens. The growth reduction may be due to changes in expression of digestive …

The Pacemaker Function of the Small Intestine
… were found to be 18 to 19 per minute in the duodenum and 14 to 15 per minute in the ileum. In the terminal ileum there was somewhat of a reversal in the gradient of rhythmicity.</p> <p>Additional evidence is presented to suggest that a duodenal pacemaker controls the normal frequency of …

Developmental Regulation of the Expression of Nutrient Transporter and BrushBorder Membrane Hydrolase Genes in the Small Intestine of Piglets
… (d 22, 24, 28, 35), and intestinal segments (duodenum, jejunum and ileum) were collected. The mRNA abundance was determined by Northern blot using specific cDNA probes for three disaccharidases (lactase-phlorizin hydrolase, LPH, sucrase-isomaltase, SI, and maltase-glucoamylase, MGA), three …

Effects of dietary soybean meal and fish meal on protein digesta flow in Holstein cows during early and midlactation
… cannulae and T-type cannulae in the proximal duodenum were used to measure digesta and nitrogen compounds flow to the small intestine during early and midlactation. Fish meal and soybean meal provided 54 and 56% of the protein in the diets composed of corn grain, corn silage and orchardgrass …

Biohydrogenation, postruminal flow, and apparent digestibility of dietary lipids in lactating Holstein cows
… cows with cannulae in the rumen and proximal duodenum were used in two 4 X 4 Latin square experiments to evaluate biohydrogenation, flow rates, and digestibility of dietary fatty acids in the gastrointestinal tract. In the first experiment, four cows were fed diets with 0% supplemental fat, 3% …

Tissue Distribution of a Peptide Transporter mRNA in Sheep, Dairy Cows, Pigs, and Chickens
… was observed with mRNA from the omasum, rumen, duodenum, jejunum, and ileum. The estimated size of mRNA was 2.8 kb. No hybridization was observed with mRNA from the abomasum, cecum, colon, liver, kidney, and semitendinosus and longissimus muscles of either species or the mammary gland of the …

In vitro absorption of valine, threonine and methionine by the small intestine of sheep
… fluids were analyzed for amino acid content. The duodenum absorbed smaller quantities of amino acids from the mucosal fluid than the jejunum and significantly (P<.01) less than the ileum. The release of amino acids from duodenal tissue was small for threonine and methionine and negative for …

Influence of molybdenum and sulfate supplementation and withdrawal of diets containing high copper broiler litter on tissue copper levels
… trial. At slaughter liver, kidney, muscle and duodenum samples were taken. Liver Cu content was increased (P<.01) by feeding broiler litter (404 vs 1543 ppm, dry basis). Liver Cu (962 ppm) accumulation and serum Cu were depressed (P<.05) by supplementing litter containing diets with Mo and SO₄. …
