Intestinal physiology in atlantic salmonpreparatory changes during smolting and after seawater entry
The intestinal physiology of teleost fishes is complex, and multiple factors contribute to an optimal osmoregulatory function. This complexity is particularly pronounced in migratory species that experience variations in environmental salinity. Consequently, this thesis employed a multifactorial …

Effect of cereal type and commensal bacteria on availability of methionine sources and intestinal physiology in pigs
… to determine the contribution of the gastrointestinal microbiota to variation in bioefficacy of methionine sources and the interrelationship between intestinal microbiota and cereal grain type with respect to gastrointestinal physiology. Apparent gastrointestinal absorption of DL-methionine …

Dietary supplementation of saccharin-based artificial sweeteners and capsicum oleoresin as a strategy to mitigate the negative consequences of heat stress on pig growth performance and intestinal physiology
… overall health. Negative aspects of gastrointestinal (GI) function, integrity and permeability also result from hyperthermia. Saccharin-based artificial sweeteners have the potential to ameliorate the negative effects of heat stress (HS) by increasing GI GLP-2 production while capsicum …

The Tissue Specific Role of Endosome Associated Protein SNX27 in Colonic Inflammation and Tumorigenesis
… in the intestines and the development of intestinal disorders remains to be unexplored. Epithelial barrier integrity, regulated by junction proteins, is critical for the maintenance of intestinal tissue homeostasis. Weakening of the intestinal barrier thus promotes susceptibility towards …

Diet Induced Alteration of the Murine Intestinal Microbiome After Antibiotic Ablation
… with non-viable Lactococcus. Appearance of intestinal yeast was dependent on the specific chow, although yeast was not detected in the chow.;Conclusion: Dead bacteria in food can modulate the intestinal microbiome. Whether and how food-derived dead bacteria alter intestinal physiology needs …

Osmoregulatory role of the intestine in fish physiology. Evolutionary, environmental, and toxicant implications
… with aflatoxin B1 on growth performance and intestinal physiology are also examined, using gilthead seabream (Sparus aurata), a well-known farmed biological model.

Design and evaluation of an instrumented microfluidic organotypic device and sensor module for organ-on-a-chip applications
… organotypic device (MOD) for culture of murine intestinal tissue and 2) a microfluidic sensor module to be implemented inline with the MOD for real-time sensing of analytes and metabolites. The MOD houses full-thickness murine intestinal tissue, including muscular, neural, immune, and epithelial …

The impact of microgravity conditions on human gut microbiome
… the precise effects of microgravity on intestinal physiology and microbial interactions remain largely unexplored. This PhD thesis investigates the impact of microgravity on the human gut microbiome through in vitro experiments, focusing on the intestinal epithelial barrier as a key …

Development of Novel Methods to Study Host-Microbe Interactions In The Larval Zebrafish Gastrointestinal Tract
… pose significant challenges to the study of intestinal physiology and pathology. Zebrafish larvae, possessing optical transparency and genetic tractability, offer an accessible and clinically relevant model for investigating dynamic events in the intestine via time-lapse imaging. In the first …

Characterisation of Guanylin and Uroguanylin in the Digestive System
… closely related peptides originating from the intestinal mucosa with established roles in salt and water homeostasis and the regulation of gut physiology. These hormones are secreted as the propeptides, ProGuanylin and ProUroguanylin, and post- translationally processed into active peptides in …

Composición de la microbiota en pacientes pediátricos con déficit de hormona de crecimiento antes y después de recibir tratamiento con hormona de crecimiento
… IGF-1, as observed in bone growth, metabolic and intestinal homeostasis, suggesting some association between the GH-IGF-1 axis and the gut microbiota. GH deficiency in children has a prevalence of 1:3,480 children, and can occur in isolation or associated to other pituitary deficits. Clinically it …

Assessment of a Nutritional Rehabilitation Model in Two Modern Broilers and Their Jungle Fowl Ancestor: A Model for Better Understanding Childhood Undernutrition
… villous atrophy, dysbiosis, and increased intestinal permeability. Inclusion of rye in poultry diets induces nutrient deficiencies and increases intestinal permeability, dysbiosis and decreases growth rates. The objective of this dissertation was to determine if chickens consuming a rye …
