Intrinsic Neural Control of Propulsion, Storage and Slow Transit in the Large Intestine.
… underlie slow transit and accommodation in the large bowel. Using electrophysiological techniques we demonstrate that circumferential stretch generates ongoing oral excitatory and anal inhibitory junction potentials in the circular muscle (CM) of both the guinea pig distal and primate sigmoid …

Neuroimmune Interactions of Enteric Neurons and Mast Cells: Friends or Foes?
… strain lead to reduced blood flow in the intestine since other organs are prioritised. One aim of this thesis was to investigate how ischemia followed by reperfusion affects the large intestine and the enteric nervous system (ENS). To do so an experimental ischemia/reperfusion (I/R) model …

Isolation and Characterization of Chitinases From Dasypus Novemcinctus, the Nine-Banded Armadillo
… visualize purification. Samples from the small intestine, proximal large intestine, and distal large intestine were aseptically collected from armadillos and used to inoculate colloidal chitin medium. Bacterial isolates were characterized using oxygen requirements, Gram stain reaction, and …

Digestion of inositol phosphates by dairy cows: Method development and application
… to investigate the disappearance of Pp from the large intestine of dairy heifers. Eight ruminally- and ileally-cannulated crossbred dairy heifers were used and each heifer was infused ileally with 0, 5, 15, or 25 g/d Pp and total fecal collection was conducted. On average 15% of total Pp entering …

Tissue- and Development-specific Expression of Proton-mediated Peptide Transporters in the Developing Chicken
… 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 gene expression. PepT1 …

Magnesium absorption in sheep infused with potassium in different parts of the digestive tract
… There was a slight absorption of Mg in the small intestine followed by a net secretion of Mg into the large intestine. Serum Mg levels tended to be depressed in the animals infused with K intraruminally. Calcium flow into the preintestinal region was decreased ( P<. 05) by infusion of K into the …

The general treatment of enteric fever
… by the use of calomel and irrigation of the large intestine.

Utilization of phosphorus and other minerals from broiler litter and swine waste
… dry matter and a higher percentage of ADF in the large intestine. Lignin was primarily digested in the large intestine of all sheep. More cellulytic bacteria were isolated from the rumen of sheep fed the supplemented diets (P< .05). Both P intake and P recycling appear to be important influences …

Signatures of gut microbes in human diseases
… investigates how bacteria residing in the human large intestine – home to the densest microbial community in the body – contribute to the pathogenesis of three distinct conditions: Parkinson’s disease (PD), inflammatory bowel diseases (IBD), and colorectal cancer (CRC).

Response of large intestinal mucosa in rats to dietary protein and fat
… ammonia is produced in greater quantities in the large intestine of rats when high protein diets are fed and that increased rates of cell proliferation of the colon mucosa are associated with the diets high in protein and fat. The objectives of this research were: (1) to determine the pH and …

Magnesium metabolism in sheep fed different levels of soluble carbohydrate and potassium
… A net secretion of magnesium into the small intestine was followed by a small net absorption in the large intestine. High levels of dietary potassium tended to depress preintestinal magnesium absorption and increase flow through the small and large intestine. Soluble carbohydrate level had no …

The effect of butyrate-supplemented total parenteral nutrition on muc2 mRNA and goblet cell chemotypes in a short bowel syndrome neonatal piglet model
… protective goblet cell chemotypes in the small intestine, specifically sulfomucins, that enhancement of protective goblet cell chemotypes in the SCFA-supplemented group will be observed, since this group also contains 9 mM butyrate, that butyrate-supplemented TPN will have a greater effect on …

Dysregulation of Noncanonical NF-κB Signaling in Gastrointestinal Diseases
… Disease/Non-Celiac Gluten Sensitivities (small intestine), Inflammatory Bowel Disease (entire intestine/large intestine), and an inflammatory subtype of colorectal cancer being Colitis-Associated Colorectal Cancer (large intestine). We study this pathway via the use of murine models bearing …

The nutritonal ecology of meadow voles (Microtus pennsylvanicus) under differing environmental conditions
… wet mass and dry mass of the stomach, small intestine, caecum, large intestine, adrenal glands, liver, and kidneys was evaluated. Data was analyzed by ANOVA using the SAS system. Meadow voles increased food intake but decreased turnover time and digestive efficiency under low ambient …

Examining Complex Microbial Communities Using the Terminal Restriction Fragment Length Polymorphism Method and Dedicated TRFLP Analysis Software
… with open air swine waste lagoon systems, the large intestine of the Trichechus manatus latirostrus, Florida manatee, and the microbial populations found in rumen fed fermentors. The community analysis methodology we developed and employed was able to not only detect large and diverse microbial …

SHORT-CHAIN FATTY ACIDS INDUCED AUTOPHAGY SERVES AS AN ADAPTIVE STRATEGY FOR RETARDING MITOCHONDRIA-MEDIATED APOPTOTIC CELL DEATH
… of undigested dietary fibers in human large intestine. SCFAs, mostly propionate and butyrate, inhibit proliferation and induce apoptosis in colon cancer cells, but clinical trials had mixed results regarding the anti-tumor activities of SCFAs. Herein we demonstrate that propionate and …
