The Role Of Nutrition In Promoting Gut Health And Treating Chronic Illness Through The Attenuation Of Inflammation, Allison Dalton

HCA Healthcare Journal of Medicine

Over the millennia, the human body and microorganisms such as bacteria, viruses, archaea, protozoa and parasites have coevolved together forming an intimate relationship. These microorganisms are found on the skin, in the mouth, genitourinary tract and most abundantly in the large intestine of the digestive tract. States of microbial dysbiosis contribute to chronic inflammation, which can lead to the pathogenesis and progression of numerous diseases. Micro- and macro-nutrients as well as dietary patterns like the Mediterranean diet can help improve health outcomes.

Scrambling The Skin: A Psychophysical Study Of Adaptation To Scrambled Tactile Apparent Motion, Tatjana Seizova-Cajic, Sandra Ludvigsson, Birger Sourander, Melinda Popov, Janet L. Taylor

Research outputs 2014 to 2021

This is an open access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited. An age-old hypothesis proposes that object motion across the receptor surface organizes sensory maps (Lotze, 19th century). Skin patches learn their relative positions from the order in which they are stimulated during motion events. We propose that reversing the local motion within a global motion sequence (‘motion scrambling’) provides a good test for this idea, and present results of the …

The Identification Of Long Non-Coding Rna Zfas1 Through An Exploratory Rna-Sequencing Analysis And Its Association With Epithelial-To-Mesenchymal Transition In Colon Cancer Adenocarcinoma., Stephen J. O'Brien

Electronic Theses and Dissertations

Colorectal adenocarcinoma is the fourth most common cancer diagnosed worldwide and is a significant cause of morbidity and mortality. This dissertation performed an exploratory RNA-sequencing analysis comparing gene expression between colon adenocarcinoma tissue and paired normal colon epithelium. After identification of a number of lncRNAs that were increased in expression in colon adenocarcinoma compared to normal colon epithelium, we aimed to validate the expression and investigate their function in vitro. Specifically, we focused on the lncRNA ZFAS1 and its association with epithelial-to-mesenchymal transition. These studies found the following: 1. Seven candidate lncRNAs were identified from the exploratory RNA-sequencing analysis to …

Rowan-Virtua School of Osteopathic Medicine Faculty Scholarship

Background: Several studies showed that there is a relationship between vitamin and mineral status and muscle strength. In particular this is the case for handgrip strength (HS) and vitamin D deficiency. In bariatric surgery there is a risk of decrease in muscle strength after surgery and also vitamin and mineral deficiencies are not uncommon. The aim of this study is to assess the effect of low vitamin 25 (OH) cholecalciferol levels, high dose cholecalciferol supplementation regime and protein intake on physical fitness, measured using handgrip strength (HS) and the shuttle walk run test (SWRT). Methods: For this retrospective …

Journal of Mind and Medical Sciences

The human microbiota is paramount for normal host physiology. Altered host-microbiome interactions are part of the pathogenesis of numerous common ailments. Currently, much emphasis is placed on the involvement of the microbiome in the pathogenesis of type-2 diabetes mellitus (T2DM), impaired glucose tolerance, and other metabolic disorders (i.e. obesity). Several studies found highly significant correlations of specific intestinal bacteria with T2DM. A better understanding of the role of the microbiome in diabetes and its complications might provide new insights in the development of new therapeutic principles.

Our pilot study investigates the microbiota patterns in Romanian type-2 diabetic patients with diabetic …

Journal of Mind and Medical Sciences

Oral lichen planus (OLP) is a chronic, immunologically mediated disease, defined by periods of exacerbation and quiescence. The disease is associated with a low mortality risk, but in some instances, morbidity can be important, especially in extensive, erosive forms, with a significant impact on the quality of life. OLP is a chronic T-cell mediated inflammatory disease involving the oral cavity, the most common lesions being located on the oral mucosa, tongue and gums. Its etiology remains in part unknown, but several factors proved to be involved in the development of the disease (drugs, dental materials, infectious agents, psychological factors, autoimmunity …

Probiotic Administration As An Adjuvant Therapeutic Treatment For Anxiety, Depression, And Cognitive Impairment Among Hypothyroid Patients, Erin R. Gorman

Selected Honors Theses

Hypothyroidism is a form of thyroid dysfunction that occurs when the thyroid gland does not make and secrete enough thyroid hormones to regulate certain processes in the body. Because thyroid hormones take part in many bodily functions, hypothyroidism can cause a large range of symptoms. Current research indicates that some strains of probiotics have beneficial effects on certain neurological and inflammatory diseases, leading to the impression that they can be used therapeutically for effective treatment of different mental health issues such as anxiety, stress, depression, and impaired memory. Because hypothyroidism often leads to such mental symptoms, it may be possible …

The Pharmabiotic For Phenylketonuria: Development Of A Novel Therapeutic, Chloé Elizabeth Lebegue

Senior Theses

Phenylketonuria, now known as phenylalanine hydroxylase (PAH) deficiency, is a genetic disorder of metabolism affecting approximately one in every 15,000 infants born in the United States. Patients have nonfunctional PAH enzyme secondary to one or more genetic mutations. The enzyme deficit results in destructive supraphysiologic blood phenylalanine levels upon consumption of the essential dietary amino acid phenylalanine. Current standards of care mitigate signs and symptoms of the disorder, but do not approach a cure. The methods for creating a prototype pharmabiotic as an innovative treatment strategy for PAH deficiency are described herein.

DNA molecular cloning techniques were utilized to engineer …

Naktide Targeted To Adipocytes Ameliorates Western Diet Induced Obesity, Rebecca D. Pratt

Theses, Dissertations and Capstones

Obesity has become a worldwide epidemic and is a major risk factor for metabolic syndrome. It is believed that cellular oxidant stress plays a key role in both the development and maintenance of obesity as well as its associated comorbidities such as diabetes, cardiovascular disease, and nonalcoholic steatohepatitis (NASH). We have previously reported that systemic administration of pNaKtide, which targets the Na/K-ATPase oxidant amplification loop was able to decrease oxidative stress and adiposity in mice fed a high fat and fructose supplemented western diet (WD). As adipocytes are believed to play an active role in the development of obesity and …

Results. Boys had a significantly higher waist circumference (71.18±9) than girls (67.46±9.91) (p=0.004). Thus 27% of boys were overweight or obese compared with only 22% of the girls. Differences were also seen between the two groups in …

Branched Short Chain Fatty Acid Isovaleric Acid Causes Smooth Muscle Relaxation Via Camp/Pka Pathway, Inhibits Gastrointestinal Motility, And Disrupts Peristaltic Movement, Bryan Adam Blakeney

Theses and Dissertations

Isovaleric Acid (IVA) is a 5-carbon branched chain fatty acid present in fermented foods and produced by the fermentation of leucine by colonic bacteria. IVA activates G-protein coupled receptors such as FFAR2, FFAR3, and OR51E1 known to be expressed on enteric neurons and enteroendocrine cells. We previously reported that the shorter, straight chain fatty acids acetate, propionate and butyrate, differentially affect colonic propulsion; however, the effect of branched chain fatty acids on gastrointestinal motility is unknown. We hypothesize that IVA relaxes smooth muscle in a cAMP/PKA dependent manner by direct action on smooth muscle cells. IVA will also decrease peristalsis …

Understanding The Role Of Phosphoinositide 3-Kinase And Its Function As A Driving Force Behind The Er Stress Response In Fibrostenotic Crohn’S Disease-Affected Ileal Smooth Muscle Cells, Prashant Yadav

Theses and Dissertations

Crohn’s disease (CD) affects about 780,000 people in the United States alone, and it is estimated that 6-15 per 100,000 persons will receive a diagnosis of this disease each year. There currently is no cure for Crohn’s disease, and available medical therapies simply serve to alleviate the inflammation. This does not help treat fibrostenosis that Crohn’s disease patients may develop, which can only be treated surgically. Finding alternatives to treat CD requires an understanding of mechanisms at the biochemical level. In this thesis, we attempted to gain a better understanding of certain pathways found to be active in Crohn’s disease-affected …

A Gut Feeling: A Hypothesis Of The Role Of The Microbiome In Attention-Deficit/Hyperactivity Disorders., Xue Ming, Neil Chen, Carly Ray, Gretchen Brewer, Jeffrey Kornitzer, Robert A Steer

Rowan-Virtua School of Osteopathic Medicine Faculty Scholarship

Attention-deficit/hyperactivity disorder (ADHD) is a neurologic disorder characterized by hyperactivity/impulsivity and/or inattentiveness, with genetic and environmental factors contributing to the disorder. With the growing recognition of the microbiome's role in many neurological disorders, the authors propose that it may also be implicated in ADHD. Here, we describe several evolving areas of research to support this hypothesis. First, a unique composition of gut bacteria has been identified and linked to behaviors in ADHD. Second, our research found an increased incidence of 2 gastrointestinal symptoms (constipation and flatulence) in children with ADHD, as compared to controls. Finally, emerging data may be interpreted …

Humans consider themselves discrete autonomous organisms, but recent research is rapidly strengthening the appreciation that associated microorganisms make essential contributions to human health and well being. Each person is inhabited and also surrounded by his/her own signature microbial cloud. A low diversity of microorganisms is associated with a plethora of diseases, including allergy, diabetes, obesity, arthritis, inflammatory bowel diseases, and even neuropsychiatric disorders. Thus, an interaction of microorganisms with the host immune system is required for a healthy body. Exposure to microorganisms from the moment we are born and appropriate microbiome assembly during childhood are essential for establishing an active …
