Epigenetic Regulation Controls Intrinsic and Extrinsic Drivers of Gastrointestinal Development
Gastrointestinal development begins with the formation of a featureless tube known as the primitive gut tube. Endodermal cells lining the inside of the gut tube differentiate into the functional epithelial units of the gastrointestinal system. Mesodermal cells surround the endodermal layer and …

Design and feedback control of self-folding untethered miniature origami robots
… robots utilizing a novel electromagnetic coil system that does not enclose the workspace of the robot. We model the magnetic field of the robot and the generated field from the electromagnetic coil system, and we explore their influences on the frequency and speed response of the robots due to …

Retrospective evaluation of the rockall risk scoring system in patients with nonvariceal upper gastrointestinal hemorrhage at a community hospital
… diagnosis and treatment of patients with upper gastrointestinal hemorrhage (UGIH), the majority of hospitals do not risk-stratify patients with UGIH. One of the major challenges in triaging patients with nonvariceal UGIH is identifying patients’ who are at low risk. We retrospectively identified …

Development of safe and ready to eat frozen oyster products using microwave steam-venting technology
… humans. Among pathogens that contaminate the gastrointestinal system of oysters, Vibrio spp (especially V. parahaemolyticus and V. vulnificus) are of greatest concern. The overall goal of the proposed study was to develop a protocol for the production of high quality and safe frozen oyster …

Stability of thin-film PEDOT:PSS electrodes for neuromodulation
… conformed to dynamic tissues like the gastrointestinal tract and simultaneously recorded electrical activity and mechanical strain. This holds immense potential for studying and treating complex gastrointestinal disorders. Beyond the gastrointestinal system, the long-term stability of …

Comparative analysis of primate hydrogenotrophic microbiota
In the human gastrointestinal system, dietary components, including fiber, that reach the colon are fermented principally to short-chain fatty acids, hydrogen and carbon dioxide. Microbial disposal of the hydrogen generated during anaerobic fermentation in the human colon is critical to the …

An oxygen-controlled in vitro model of the gastrointestinal human-microbiome interface
The gastrointestinal system plays a vital role in the functioning of the human body, processing food into useable energy, controlling homeostasis, and serving 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 …

The role of gastric and small intestinal mechanisms in postprandial hypotension.
Postprandial hypotension, defined as a fall in systolic blood pressure of ≥ 20 mmHg, within two hours of a meal, leading to syncope, falls, dizziness and angina, occurs frequently in the elderly and is now recognised as an important clinical problem. In healthy young and older individuals, meal …

Uncovering Signalling Pathways Mediating Gastrointestinal Morphogenesis and Tumorigenesis
The gastrointestinal system undergoes remarkable morphogenesis during development, in which a simple, smooth tube rapidly rearranges to form millions of finger-like projections called villi that line the entire intestinal tract. While gastrointestinal development requires precisely coordinated …

Influence of Physiological State, Prolonged Dry Storage, and Passage through Simulated Digestion on the Survival and Gene Expression of Salmonella enterica sv. Tennessee
… were tested for survival through a simulated gastrointestinal system. RNA was extracted at the identical time points and relative gene expression determined for genes associated with stress response (rpoS, otsB), virulence (hilA, hilD, invA, sipC) and a housekeeping gene 16S rRNA using …

Development Of Bioelectronic Sensors For Real Time Monitoring Of Gastrointestinal Health
The work outlined in this thesis focuses on the gastrointestinal (GI) system, which plays an essential role in maintaining homeostasis within the body, by facilitating digestion, nutrient absorption, and waste excretion. Beyond its fundamental functions, the GI system is intricately connected to …

Development and applications of high speed and hyperspectral nonlinear microscopy
… from endogenous contrast is presented. This system was applied to visualize and identify sources of endogenous contrast in gastrointestinal tissues, providing robust references for the assessment of normal and diseased tissues. Secondly, three methods for high speed volumetric imaging using …

The Recruitment and Function of Tumor Microenvironment Components During Gastric Carcinogenesis
Helicobacter felis (H. felis) infection has been used for numerous years as a standard model of gastric carcinogenesis and recapitulates the pathogenesis seen with human Helicobacter pylori infection. H. felis induces a a wide array of chronic low grade inflammatory responses, some of which …
