Static Mechanical Characteristics of the Small Collecting Vein and the First-Order Venule in the Denervated Small Intestines of the Wistar, Wistar-Kyoto, and Spontaneously Hypertensive Rats
This study was centered around two basic themes. The first related to the mechanics of the venous system, the second to venous function in hypertension. Since the venous system holds a large fraction of the total peripheral blood volume (and much of this possibly located in the venous …

Assessing the Effects of Temperature, Feeding Status, and the Microbiome on the Maximal Activities of Several Enzymes Important to Energy Production and Ammonia Detoxification in the Intestines of Teleost Fish
… and ammonia (NH3) detoxification in the intestines of three species of teleosts: the goldfish, rainbow darter and central stoneroller. In warm-acclimated goldfish, intestinal and branchial tissues were more responsive to feeding, while renal tissues were not affected by digestion or …

Characterization of the carbohydrate receptors of the <i>Clostridium difficile</i> enterotoxin
… in hamsters. This organism can colonize the intestines after antibiotic therapy disrupts the normal intestinal microflora. Once established in the intestines, the organism causes disease by producing two toxins, designated toxin A and toxin B. Only toxin A is active on intestinal epithelium, …

Validation of the Fung double tube to enumerate Clostridium perfringens from the intestinal contents of broiler chickens raised on different diets
… detect and enumerate C. perfringens in chicken intestines. Two methods (FDT and petri plates) and three media (Shahidi Ferguson Perfringens [SFP] with egg supplement, polymyxin B [p], and kanamycin [k; E]; SFP with p and k [P]; and SFP with cycloserine [C]) were arranged in a 2 x 3 factorial, …

Adaptive immune responses in intestinal homeostasis and experimental inflammatory bowel disease
… plasticity and functions of CD4+ T cells in intestines are intensely studied, but still incompletely defined. The differentiation of peripherally induced Tregs and Th17 cell population is reciprocally regulated in the intestine. In addition to the regulation by master transcriptional factors …

The Gut Microbiome: Is Fecal Matter Microbial Composition a Proxy for Intestinal Microbial Composition in Studies of the Microbiome
… between stool and the different portions of the intestines tested. Uni-variate analysis shows significance between the two main phyla Firmicutes and Bacteroidetes, as well as main genera like <em>Odoribacter, Porphyromonas </em>and <em>Alistipes. </em>Relevant species <em>Desulfovibrio …

Food Habits and Placental Scar Counts of Bobcats in South Dakota
… and deer occurred in 58, 36, and 9% of bobcat intestines, respectively. Occurrences in rabbits decreased from 67% of bobcat stomachs in 1978-79 to 48% in 1979-80. Occurrence of rats and mice in the intestines increased from 26% in 1978-79 to 43% in 1979-80. Bobcats collected exhibited a sex …

Host-Microbiota Interactions
… found that the interaction network in the large intestines is sparse compared to the network in the small intestines. We postulate that the sparse interaction is due to a specialized role of microbiota in the large intestines and may explain the associations between altered microbiota and CRC. We …

Novel effects of Prefoldin Pathway on Intestinal Homeostasis via Dietary Restriction in Drosophila melanogaster
… factors, one of which is the maintenance of the intestines of the organism. Homeostasis of the intestines is controlled by the regulation of intestine cell apoptosis and intestine cell proliferation. My research explores the role of two protein subunits found in a complex which may have possible …

An oxygen-controlled in vitro model of the gastrointestinal human-microbiome interface
… as the front line of the immune system. The intestines are aided in their many functions by the gut microbiome, a collection of 100 trillion anaerobic bacteria cells that live inside the GI tract. Although they play an essential part in the organ system, they remain little-represented in in …

Fibre fermentation in the pig intestine : effect on metabolite production and nitrogen excretion
… of DF, especially the soluble fraction, in pig intestines yields short-chain fatty acids (SCFA) and lactic acid, which have been found to improve gut health by favouring the growth of health-promoting bacteria such as Lactobacilli and Bifidobacteria, at the expense of pathogenic ones like …

Binding mechanism of K88ab pili produced by enterotoxigenic Escherichia coli
… brush border membranes were prepared from small intestines obtained from 2-, 21-, and 42-day-old piglets as well as adult hogs. Binding of K88ab pili by mucus polypeptides was greater when prepared from small intestines obtained from 2-day-old piglets than from piglets of other ages and adult …

Baylisascaris procyonis Prevalence and Impact in Raccoon (Procyon lotor) Populations
… is a nematode parasite that infects the small intestines of raccoons (Procyon lotor). Raccoons are the definitive host for this parasite, which can have both an indirect and direct life cycle. In intermediate hosts, the parasite causes serious pathology resulting from larvae migrating through …

Digesta Passage, Fermentation, and Microbes in the Hindgut and Its Relative Contribution to the Nutrition of Cattle
… cecum and colon and digesta passage through the intestines were investigated in a series of experiments. Specific gravity, but not length, of inert particles affected their passage through the intestines. Passage was quickest for particles with a specific gravity of 1.17 and slowest for those …
