  1. 1. The Effects of Temperature on Gut Blood Flow and Gut Motility in Fish

    Författare :Albin Gräns; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Fish; thermoregulatory behaviours; electrical activity; biotelemetry;

    Sammanfattning : In order for a fish to grow and thrive, the gut must function efficiently. This is achieved through a range of processes, including controlled patterns of gut motility and modifications in gut blood flow. How these processes are affected by long and short-term changes in ambient temperature was the main focus of this thesis. LÄS MER

  3. 2. Gut Feelings - From Brain to Gut and from Lumen to Gut

    Författare :Xiaowen Cheng; Neurogastroenterologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Enteric nervous system; cerebral ischemia; galectine-3; tuft cell; CGRP; CCK; GLP-1; 5HT; PYY;

    Sammanfattning : Part 1: From Brain to GutThe brain is an organ with a high energy requirement. To meet this demand, the brain needs a continuous and well-regulated blood supply. In situations where the brain, or parts of the brain, does not receive sufficient blood flow injury arise. LÄS MER

  4. 3. On the Aggregation of Cereal β-Glucan and its Association with other Biomolecules : A Study using Asymmetric Flow Field-Flow Fractionation (AF4)

    Författare :Claudia Zielke; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :ß-glucan; polysaccharides; dietary fiber; field flow fractionation; Asymmetric flow field-flow fractionation AF4 ; Multiangle light scattering MALS ;

    Sammanfattning : During recent years, numerous studies have shown the ability of dietary fiber toprotect the colon from disease and to improve intestinal health. Beneficial healtheffects, such as the lowering of blood cholesterol levels and a reduction in the risk of coronary heart disease, are often directly related to cereal β-glucan, one of the major components of dietary fiber found in oat and barley.

  5. 4. Adrenergic control of small intestinal motility and blood flow : an experimental study in rat and man

    Författare :Mikael Thollander; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :clonidine; computerized recording; intestinal blood flow; isoprenaline; laser Doppler flownretry; manometry; migrating motor complex; oxymetazoline; propranolol; small intestine;

    Sammanfattning : Small intestinal motility in the fasted state is characterized by migrating motor complexes (MMCs). Both animals and man exhibit the MMC, which consists of periods of regular contractions, i.e. activity fronts, that migrate along the length of the small bowel and alternate with periods of quiescence.

  7. 5. Specification of enteric neuron subtypes in the developing gut

    Författare :Viktoria Knoflach; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The enteric nervous system (ENS) is the biggest subdivision of the peripheral nervous system and harbors more neurons than the spinal cord. Its intricate network of ganglia is spanning the entire length of the gastrointestinal wall from where it controls peristalsis, secretion and blood flow. LÄS MER
