The Pacemaker Function of the Small Intestine
… of the gradient of rhythmicity in the small intestine of the unanesthetized dog. The gradient of rhythmicity was studied on five dogs prepared with duodenal fistulas. Rhythmic contractions were recorded from the small intestine by a small rubber balloon. The gradient of rhythmicity was …

Absorption of Chromium Across the Rat Small Intestine
… chromium across different regions of rat small intestine was investigated using the everted sac technique. A very small percentage of chromium was transported to the serosal compartment, and a larger percentage of chromium was rapidly taken up by the intestinal tissue. There was no …

Apolipoprotein biosynthesis and turnover in mammalian small intestine
The mammalian small intestine is a major site (second in total activity only to the liver) for the synthesis and secretion of plasma apolipoproteins, and contributes significantly to overall whole-body lipid dynamics. A prominent feature of the small intestine is its exposure to periodic loads of …

Dexamethasone- and age-sensitive genes in neonatal small intestine
… with the developmental (aging) process of the intestine. To identify fructose-responsive genes whose expression also changes with age, intestines of 10 and 20 d old pups were perfused, by Ferraris et al., with fructose and then compared by microarray analysis. From this, a gene clustering …

Epithelial Cell Autophagy in Antibacterial Defense of the Small Intestine
The intestines of all mammals are colonized with a diverse microbiota that provide metabolic benefits to their hosts. However, this symbiotic relationship can break down when resident bacteria opportunistically invade the intestinal barrier, leading to pathologies such as inflammatory bowel disease …

Membrane potentials in the isolated small intestine of the bullfrog
This document only includes an excerpt of the corresponding thesis or dissertation. To request a digital scan of the full text, please contact the Ruth Lilly Medical Library's Interlibrary Loan Department (rlmlill@iu.edu).

Modelling of physical and chemical processes in the small intestine
Chemical and physical processing in the small intestine is an important step for food digestion and absorption. Having reviewed the literature, a relevant model has been developed which enabled investigation into the fluid flow, mixing mechanisms and delivery of nutrients to the wall of the model …

Altering Amino Acid Supply to the Small Intestine in Ruminants
… to modify the flow of amino acids (AA) to the small intestine (SI) in ruminants. In Experiment 1, five steers (450 kg) with cannulas in the rumen, proximal duodenum, and terminal ileum were used in a 5 x 5 Latin square design to evaluate the site and extent of digestion of nitrogenous compounds …

Non-Canonical Roles of Cytosolic Phosphoenolpyruvate Carboxykinase in Small Intestine Metabolism
… fatty acid esterification; enterocytes of the small intestine, for amino acid oxidation; and most famously, gluconeogenesis in the liver. Though amino acid, fatty acid, and glucose metabolism of the small intestine have been well studied, no investigation has emphasized the role of intestinal …

Transport of Folic Acid and Related Compounds Across the Small Intestine
… was localised in the proximal region of the small intestine. The uptake of folic acid by a preparation of isolated jejuna! mucosal cells was studied, together with some aspects of their morphology. The interpretation of these results is discussed at some length in the light of the previous …

Apoptosis in the equine small intestine following experimental ischemia-reperfusion injury
… at characterizing the apoptotic response equine small intestine subjected to experimental ischemia-reperfusion injury and determining if use of an angiotensin converting enzyme inhibitor (enalaprilat) would ameliorate the apoptotic response. It was designed to determine if mucosal epithelial …

Effects of high incubation temperature on the developing small intestine and yolk sac of broiler chicks with insight into goblet cell development in the small intestine early posthatch
… (37.5°C versus 39.5°C) on the developing small intestine and yolk sac, which provide the chick with nutrients posthatch and during embryogenesis. Studying these organs and mechanisms occurring during this time could potentially indicate why chicks from eggs subjected to a higher incubation …

Analysis of a model to describe lead transport by the small intestine
… the mechanism of lead transport across the rat small intestine were conducted using the in vitro everted sac technique. The data obtained were used to construct a model which could competently rationalise some of the reported observations in the literature concerning intestinal lead transport. …

Non-electrolyte transport in brush border membrane vesicles from bovine small intestine
Transport properties of bovine intestinal brush border membranes were investigated. Isolation of brush border membrane vesicles involved magnesium precipitation followed by a sucrose density gradient. Characterization by alkaline phosphatase activity (the brush border marker enzyme) showed 7 fold …

Small intestine slow wave activity defined through in vivo high-resolution electrical mapping
The small intestine is characterised by underlying rhythmic bioelectrical potentials that propagate along the organ in a coordinated fashion; these propagating biopotentials are termed slow waves, and they serve a vital role in the regulationand organisation of intestinal motility. Most previous …

The role of mucin in establishment of Escherichia coli in porcine small intestine
… and proteolysis of mucous gel from porcine small intestine. Mucin prepared in this study contained (by weight) 37.2% protein, 58.7% carbohydrate (4.6% fucose, 9.4% mannose, 10.7% sialic acid, 13.5% galactose, and 20.5% hexosamine), and 3.7% ester sulfate. Fractionation of mucin on Sepharose …
