Gastrointestinal Function, Damage and Symptoms During Exercise and the Potential Therapeutic Role of Probiotic Supplementation
Gastrointestinal (GI) symptoms are widely reported in athletes participating in prolonged endurance events including; cyclists, triathletes and marathon runners, although there is a large estimated range of between 4–96% of participants affected (Costa et al., 2017a). Two potential causes of …

Non-invasive assessment of gastrointestinal function using breath test technology : investigations in health and disease.
Assessment of gastric emptying in animals is hampered by the lack of a technique that is noninvasive and does not involve sacrificing the animal. The primary aims of these studies therefore were to develop the breath test for the mouse and then investigate gastric emptying rates in physiological, …

Does the Intensity, Mode, and Timing of Exercise Affect Postprandial Gastrointestinal Function, Metabolic Responses and Energy Intake in Healthy Men
… (intensity, mode, or timing) might affect gastrointestinal function, metabolic responses, appetite, and energy intake (EI), and as a result support the development of novel non-pharmacological interventions for weight management. The main findings of this thesis were as follows. Gastric …

INVESTIGATION OF ACUTE STRESS IMPACT ON NURSERY PIG GASTROINTESTINAL FUNCTION AND ABILITY OF BIOACTIVE COMPONENTS OF GARLIC TO MITIGATE STRESS-INDUCED PHYSIOLOGICAL CHANGES
… deprivation on nursery pig growth performance, gastrointestinal function, and ability of garlic-derived diallyl disulfide (DADS) and diallyl trisulfide (DATS) to mitigate deprivation-induced effects. For the first experiment, the effects of a 24-h post-weaning feed, water, or feed + water …

The role of the free fatty acid, lauric acid, in appetite regulation and its potential as an appetite-suppressant.
… fat, in the small intestine modulates gastrointestinal function and subsequent energy intake, and it is well established that the digestion of fat into free fatty acids is required for these effects to occur. Furthermore, the effects of fatty acids are dependent on their chain length. …

Corticotropin-releasing factor and acute post-operative gut function in truamatic abdominal injury and elective abdominal surgery
… suggests that peripheral CRF is present in the gastrointestinal tract and associated with inflammatory changes. Critically ill patients frequently display somewhat unexplained gastrointestinal dysfunction including delayed gastric emptying, ileus and increased bowel permeability. The aim of the …

Immune and stress factors in the pathophysiology of the mdx mouse model of Duchenne Muscular Dystrophy
… disorders such as depression and anxiety and dysfunction of the gastrointestinal tract. The first study in the thesis examined mood in the dystrophin-deficient mdx mouse model of DMD and examined the effects of the tri-cyclic antidepressant, amitriptyline on behaviours. Amitriptyline had …

The impact of microgravity conditions on human gut microbiome
… overall health by regulating metabolism, immune function, and neurological processes. Disruptions to its balance can lead to various health complications. Space exploration introduces unique environmental challenges, particularly microgravity, which can significantly alter the composition and …

The relationship between enteral nutrition, energy metabolism and gut homeostasis during the course of critical illness.
Nutrition has an indirect effect on the gastrointestinal function of the host and thereby on health, mainly by influencing the composition and activity of the human gut microbiota. The aim of this PhD project was to investigate the effect of nutrition as a factor affecting the intestinal …

Route of Nutrient Administration Alters Intestinal Immune Cell Composition in Neonatal Piglets
… requirements and developmentally immature gastrointestinal function and are supported totally or partially on parenteral nutrition for several days to weeks postpartum. The use of total parenteral nutrition (TPN) is frequently associated with a myriad of complications, primarily due to the …

The effect of intravenous fluids and other factors on patient recovery following elective abdominal surgery
… not significantly improve recovery in terms of gastrointestinal function (4.2 (3.2-6.9) versus 4.7 (3.7-6.1) days; p=0.80) or hospital stay (5.9 (4.0-7.9) versus 5.8 (4.1-7.3) days; p=0.90). Analysing our findings in the context of what is already known suggests that the immediate perioperative …

Investigating the influence of dietary fiber source and multicarbohydrase supplementation on digestibility, energy, systemic health, water balance, and gut motility in gestating sows
… improve energy and nutrient digestibility and gastrointestinal function of growing pigs. However, research on their effectiveness in gestation diets is limited. The experimental objective was to evaluate the efficacy and mechanisms associated with multicarbohydrases in gestating sows fed …

The role of dietary arachidonic acid and docosahexaenoic acid in preventing the phenotype observed with highly unsaturated fatty acid deficiency
… understood. In order to study specific functions for AA and DHA, a delta-6 desaturase knockout (D6D-/-) mouse was created. D6D is a key enzyme in synthesizing HUFA from the precursor dietary essential fatty acids, linoleic acid (LA, 18:2ω6) or α-linolenic acid (ALA, 18:3ω3). By …

Effects of epidermal growth factor on gastrointestinal development and function for improved growth and efficiency in poultry
… factor (EGF), a potent mitogen for neonatal gastrointestinal development, has demonstrated its protective role in supporting and healing the gastrointestinal tract of mammalian models. However, EGF has not been thoroughly assessed for its ability to stimulate gastrointestinal development in …
