Gut Microbiota And The Development Of Type 2 Diabetes, Janet Ryan
Gut Microbiota And The Development Of Type 2 Diabetes, Janet Ryan
Nursing | Senior Theses
This paper explores the question: Can interventions focusing on healing the gut microbiome of a prediabetic patient prevent or delay the onset of type 2 diabetes? Diabetes is a major health problem that is becoming the biggest epidemic of the 21st century. Efforts to derail the progression of disrupted blood glucose metabolism are often futile leaving patients frustrated with a lifelong burden of disease management. Recent studies suggest that collectively the gut microbiome acts as an endocrine organ and that injury to this “organ” can lead to dysfunctional glucose regulation. A comprehensive literature review revealed that further studies are …
Investigating Microbial And Host Factors That Modulate Severity Of Clostridioides Difficile Associated Disease, Armando Lerma
Investigating Microbial And Host Factors That Modulate Severity Of Clostridioides Difficile Associated Disease, Armando Lerma
Department of Food Science and Technology: Dissertations, Theses, and Student Research
Clostridioides difficile is recognized as one of the most important pathogens in hospital and community healthcare settings. The clinical outcome of infection of toxigenic C. difficile infection (CDI) ranges from asymptomatic colonization to fulminant pseudomembranous colitis and death. In recent studies, it has been suggested that a high proportion of nosocomial CDI cases are transmitted from asymptomatic carriers which might be acting as infection reservoirs. Understanding what causes the different responses to infection could lead to the development of novel prevention and treatment strategies. Although several explanations have been proposed to explain variations in susceptibility, understanding of the exact mechanisms …
Human Respiratory And Gut Microbiomes - Do They Really Contribute To Respiratory Health?, Juliana Durack, Claus T. Christophersen
Human Respiratory And Gut Microbiomes - Do They Really Contribute To Respiratory Health?, Juliana Durack, Claus T. Christophersen
Research outputs 2014 to 2021
© Copyright © 2020 Durack and Christophersen. Human gastrointestinal and respiratory tracts are colonized by diverse polymicrobial communities shortly after birth, which are continuously molded by environmental exposure. The development of the resident microbiota in early life is a critical factor in the maturation of a healthy immune system. Disturbances to the intricate relationship between environmental exposure and maturation of the infant microbiome have been increasingly identified as a potential contributor to a range of childhood diseases. This review details recent evidence that implicates the contribution of gut and airway microbiome to pediatric respiratory health.
Irritable Bowel Syndrome, Katherine Stillman
Irritable Bowel Syndrome, Katherine Stillman
Nursing Student Class Projects (Formerly MSN)
Past understanding of the pathophysiology of irritable bowel syndrome (IBS) presents this chronic condition as a functional gastrointestinal disorder related to psychological causes. While no structural abnormalities are present in IBS, this poorly understood condition of persistent abdominal pain and altered bowel habits can be debilitating, contributing to a decreased quality of life. Current research has uncovered new evidence, that for many patients, symptoms may actually originate in the gut. An altered gut microbiome is now accepted as playing a central role in the development of the disorder. This poster summarizes the current pathophysiological concepts of IBS, including the role …

Multiple sclerosis (MS) is the most common autoimmune disorder affecting the central nervous system. Epstein-Barr virus (EBV) is a causative agent for infectious mononucleosis (IM) that is associated with MS pathogenesis. However, the exact mechanism by which EBV, specifically in IM, increases the risk for MS remains unknown. EBV immortalizes primary B lymphocytes in vitro and causes excessive B lymphocyte proliferation in IM in vivo. In asymptomatic carriers, EBV-infected B lymphocytes still proliferate to certain degrees, the process of which is tightly controlled by the host immune systems. Experimental autoimmune encephalomyelitis (EAE) mimics key features of MS in humans …
Fecal Microbiota Transplantation And Gut Microbiome Effects On Psychiatric Illnesses, Mona Seresht
Fecal Microbiota Transplantation And Gut Microbiome Effects On Psychiatric Illnesses, Mona Seresht
Physician Assistant Studies | Student Articles
Despite the medical advances that have been made in regards to mental health, psychiatric medications, and alternative therapies, many patients continue to suffer day in and day out, unable to live the type of life they desire. Many times, the medication route includes many episodes of trial and error, side effects, and no significant improvement in actual symptoms. Therapy, although effective, typically necessitates a supplemental medication for the best results. Fecal microbiota transplantation (FMT) is a method where feces from a healthy donor is transferred to an affected patient, typically via colonoscopy. Theoretically, this alters the gut microbiome in a …
Anti-Aggregation Effects Of Phenolic Compounds On Α-Synuclein, Kenjiro Ono, Mayumi Tsuji, Tritia R. Yamasaki, Giulio M. Pasinetti
Anti-Aggregation Effects Of Phenolic Compounds On Α-Synuclein, Kenjiro Ono, Mayumi Tsuji, Tritia R. Yamasaki, Giulio M. Pasinetti
Neurology Faculty Publications
The aggregation and deposition of α-synuclein (αS) are major pathologic features of Parkinson's disease, dementia with Lewy bodies, and other α-synucleinopathies. The propagation of αS pathology in the brain plays a key role in the onset and progression of clinical phenotypes. Thus, there is increasing interest in developing strategies that attenuate αS aggregation and propagation. Based on cumulative evidence that αS oligomers are neurotoxic and critical species in the pathogenesis of α-synucleinopathies, we and other groups reported that phenolic compounds inhibit αS aggregation including oligomerization, thereby ameliorating αS oligomer-induced cellular and synaptic toxicities. Heterogeneity in gut microbiota may influence the …

Micom: Metagenome-Scale Modeling To Infer Metabolic Interactions In The Gut Microbiota., Christian Diener, Sean M Gibbons, Osbaldo Resendis-Antonio
Articles, Abstracts, and Reports
Compositional changes in the gut microbiota have been associated with a variety of medical conditions such as obesity, Crohn's disease, and diabetes. However, connecting microbial community composition to ecosystem function remains a challenge. Here, we introduce MICOM, a customizable metabolic model of the human gut microbiome. By using a heuristic optimization approach based on L2 regularization, we were able to obtain a unique set of realistic growth rates that corresponded well with observed replication rates. We integrated adjustable dietary and taxon abundance constraints to generate personalized metabolic models for individual metagenomic samples. We applied MICOM to a balanced cohort of …

Characterizing The Composition Of The Pediatric Gut Microbiome: A Systematic Review, Kane E. Deering, Amanda Devine, Therese A. O’Sullivan, Johnny Lo, Mary C. Boyce, Claus T. Christophersen
Research outputs 2014 to 2021
The consortium of trillions of microorganisms that live inside the human gut are integral to health. Little has been done to collate and characterize the microbiome of children. A systematic review was undertaken to address this gap (PROSPERO ID: CRD42018109599). MEDLINE and EMBASE were searched using the keywords: “healthy preadolescent children” and “gut microbiome” to 31 August 2018. Of the 815 journal articles, 42 met the inclusion criteria. The primary outcome was the relative abundance of bacteria at the phylum, family, and genus taxonomic ranks. α-diversity, short chain fatty acid concentrations, diet, 16S rRNA sequencing region, and geographical location were …

GENE–ENVIRONMENT INTERACTION IN PARKINSON DISEASE: THE GUT MICROBIOME ZACHARY D. WALLEN GENETICS, GENOMICS, AND BIOINFORMATICS ABSTRACTParkinson disease (PD) is a progressive neurodegenerative disease with no cure. Majority of cases are idiopathic, and the cause is unknown. Studies have been conducted in human and animals to identify PD risk factors, resulting in a list of genetic and environmental factors that modestly increases risk of PD. Still, no individual risk factor fully explains the cause of PD, and neither has the combination of these factors. Additional avenues of research are being investigated to find potential triggers of PD, and factors that might …
