The Link Between Heart Disease In Low Socioeconomic Communities In America, Khristopher Chea

Nursing | Senior Theses

As a future medical professional in the healthcare field, we continue to see patients admitted for cardiovascular issues. Cardiovascular diseases (CVDs) remain the leading cause of mortality among adults living in the U.S. despite advances in treatment throughout the past century. A number of risk factors such as hypertension, obesity, smoking, and physical inactivity contribute to the significant rise of cardiovascular disease. Research data suggests that there is correlation between cardiovascular disease, low socioeconomic status, and diet. According to the American Phycological Association socioeconomic status is measured by income, educational status, and occupation, and has been shown to be closely …

Vitamin D Levels Affect Survival In A Bcr-Abl Acute Lymphoblastic Leukemia Mouse Model But Do Not Cause Vitamin-Drug Interactions, Kavya Annu

Theses and Dissertations (ETD)

It is a well-established phenomenon that dietary components containing CYP3A inducers or inhibitors if co-administered with drugs that are CYP3A4 substrates lead to marked drug-drug interactions. Because vitamin D is known to regulate intestinal CYP3A expression and gut CYP3A expression plays an important role in pre-systemic metabolism of CYP3A drugs, we determined the impact of vitamin D (VD3) status on systemic exposure and efficacy of chemotherapeutic agents that are CYP3A substrates. We employed VD3 sufficient and deficient mice to perform pharmacokinetics (PK) and anti-leukemic efficacy studies.

First, using hCYP3A4 transgenic mouse model we evaluated the intestinal, hepatic and renal expression …

Therapeutic Potential Of A Ketogenic Diet In The Treatment Of Major Depressive Disorder, Jordan A. Murrin

Masters Theses, 2020-current

Major depressive disorder (MDD) is the second most common mental health condition and a leading cause of disability in the world. It is theorized that MDD develops from a combination of biological, psychological, and social stressors. The condition is typically treated using pharmaceuticals and psychotherapy. However, not all individuals with MDD have access to or choose to use these treatments, or may prefer to incorporate therapeutic lifestyle changes such as exercise, sleep, and healthy eating. Even with treatment, MDD can alter brain structure and function, leading to the development of comorbid mental health and chronic metabolic conditions like obesity, cardiovascular …

Nutraceutical Potential For Alzheimer's Disease Treatment, Alex Gewecke

Undergraduate Research Journal

Alzheimer’s disease (AD) is a progressive disorder involving buildup of excessive amounts of proteins such as beta amyloid in the brain that leads to memory loss, inability to perform daily functions, and an early death. By 2060, the number of cases is forecast to nearly triple current numbers. Age is the primary risk factor for AD and no new drugs have been approved since 2003. Nutraceuticals, a broad category of substances that can be utilized for both medicinal and nutritional purposes may be able to help, which is why they are being more widely researched. Overall, a number of attempts …

Physiochemical Characteristics Of Hot And Cold Brew Coffee Chemistry: The Effects Of Roast Level And Brewing Temperature On Compound Extraction., Niny Z. Rao, Megan Fuller, Meghan D Grim

College of Life Sciences Faculty Papers

The role of roasting in cold brew coffee chemistry is poorly understood. The brewing temperature influences extraction processes and may have varying effects across the roast spectrum. To understand the relationship between brew temperature and roast temperature, hot and cold brew coffees were prepared from Arabica Columbian coffee beans roasted to light, medium, and dark levels. Chemical and physical parameters were measured to investigate the relationships among degree of roast, water temperature, and key characteristics of resulting coffees. Cold brew coffees showed differential extraction marked by decreased acidity, lower concentration of browned compounds, and fewer TDS indicating that cold water …

Effects Of Acute Cocoa Supplementation On Postprandial Apolipoproteins, Lipoprotein Subclasses, And Inflammatory Biomarkers In Adults With Type 2 Diabetes After A High-Fat Meal, Dustin D. Davis, Rickelle Tallent, James W. Navalta, Anthony Salazar, Timothy J. Lyons, Arpita Basu

Integrated Health Sciences Faculty Publications

Dyslipidemia and inflammation exacerbate postprandial metabolic stress in people with diabetes. Acute dietary supplementation with polyphenols shows promise in improving postprandial metabolic stress in type 2 diabetes (T2D). Cocoa is a rich source of dietary polyphenols with demonstrated cardioprotective effects in adults without diabetes. To date, the acute effects of cocoa on postprandial lipids and inflammation have received little attention in the presence of T2D. This report expands on our earlier observation that polyphenol-rich cocoa, given as a beverage with a fast-food-style, high-fat breakfast, increased postprandial high-density lipoprotein-cholesterol (HDL-C) in adults with T2D. We now test whether polyphenol-rich cocoa modulated …

The Trait Repertoire Enabling Cyanobacteria To Bloom Assessed Through Comparative Genomic Complexity And Metatranscriptomics, Huansheng Cao, Yohei Shimura, Morgan M. Steffen, Zhou Yang, Jingrang Lu, Allen Joel, Landon Jenkins, Masanobu Kawachi, Yanbin Yin, Ferran Garcia-Pichel

Food for Health: Publications

Water bloom development due to eutrophication constitutes a case of niche specialization among planktonic cyanobacteria, but the genomic repertoire allowing bloom formation in only some species has not been fully characterized. We posited that the habitat relevance of a trait begets its underlying genomic complexity, so that traits within the repertoire would be differentially more complex in species successfully thriving in that habitat than in close species that cannot. To test this for the case of bloom-forming cyanobacteria, we curated 17 potentially relevant query metabolic pathways and five core pathways selected according to existing ecophysiological literature. The available 113 genomes …

The Impact Of Stress On Diet, Sleep, And Exercise Amongst College Students, Jessica Rizzo

Senior Honors Projects

Stress is something that everyone faces in their lifetime and has an everlasting impact on their health. College students face high levels of stress throughout the semester, but how is that impacting their behavior? I conducted a survey alongside Dr. Melanson, a professor in the Department of Nutrition and Food Sciences, to see just how college students are reacting to stress. The survey was circulated to different departments and classes to achieve a widespread collection of data. The survey remained completely anonymous and posed questions about eating, exercise, and sleep habits, along with questions on demographics and stress levels. Our …

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.

Journal of Mind and Medical Sciences

Background: Compassionate caregiving is a critical skill for workers among the helping professions, but the degree of empathy required by caregivers can place high demands on their mental and emotional resources. While many professionals employ successful coping strategies to mitigate these stressors, others experience compassion fatigue or burnout from emotional exhaustion. The objective of this research was to evaluate the relationships between caregivers’ demographic/career variables, compassion satisfaction, compassion fatigue, and psychodynamic defense mechanisms such as suppression, repressive function, regression in the service of the Ego, and rationalization. Methods: Participants were 250 caregivers with 178 (71,2%) women and 72 men (28,8%) …

Optimisation Of Vitamin D Status For Enhanced Immuno-Protection Against Covid-19, Daniel Mccartney, Declan G. Byrne

Articles

Abstract

Background

Vitamin D deficiency (serum 25(OH)D<50nmol/l) is common in Ireland, particularly amongst older adults, hospital inpatients and nursing home residents. Vitamin D deficiency is associated with increased risk of acute viral respiratory infection and community acquired pneumonia, with several molecular mechanisms proposed to explain this association. Vitamin D supplementation has also been shown to reduce the risk of respiratory infection.

Vitamin D and Covid-19

Correction of vitamin D deficiency is thought to suppress CD26, a putative adhesion molecule for Covid-19 host cell invasion. Vitamin D may also attenuate interferon gamma (IFNγ) and interleukin-6 (IL-6) inflammatory responses, both potent predictors of poorer outcome in critically-ill ventilated patients including those with Covid-19.

Vitamin D Requirements

Irish adults require 25-30μg/d of vitamin D3, an intake not achievable by diet alone, to reliably maintain serum 25(OH)D levels >50nmol/l. Supplementation with doses up to 100μg/d has been shown to be safe for adults, and many agencies and expert …

Use Of A Novel Whole-Body Imaging Approach To Predict Resting Metabolic Rates In Athletes, Nicole Vencil

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Prediction of energy expenditure allows for calculation of appropriate energy requirements, which is especially important for athletes. Resting metabolic rate (RMR) is the greatest contributor to total daily energy expenditure (TDEE) and is typically measured via indirect calorimetry. Indirect calorimetry is not always available, which results in the need for predictive equations. Most predictive equations have been developed with participants resembling the general population and have not been found to be appropriate for athletes, as they may incorrectly predict RMR due to the unique differences of body composition between athletes and the general population. The purpose of the present study …

Adverse Maternal Environment And Western Diet Impairs Cognitive Function And Alters Hippocampal Glucocorticoid Receptor Promoter Methylation In Male Mice., Xingrao Ke, Qi Fu, Jennifer Sterrett, Cecilia J. Hillard, Robert H. Lane, Amber Majnik

Manuscripts, Articles, Book Chapters and Other Papers

Adverse maternal environment (AME) and high-fat diet in early childhood increase the risk of cognitive impairment and depression later in life. Cognitive impairment associates with hippocampal dysfunction. A key regulator of hippocampal function is the glucocorticoid receptor. Increased hippocampal GR expression associates with cognitive impairment and depression. Transcriptional control of GR relies in part upon the DNA methylation status at multiple alternative initiation sites that are tissue specific, with exon 1.7 being hippocampal specific. Increased exon 1.7 expression associates with upregulated hippocampal GR expression in early life stress animal models. However, the effects of AME combined with postweaning western diet …

Potential Use Of Biotherapeutic Bacteria To Target Colorectal Cancer-Associated Taxa, Gareth Lawrence, Maire Begley, Paul D. Cotter, Caitríona M. Guinane

Department of Biological Sciences Publications

The role of the gut microbiome in human health and disease is the focus of much attention. It has been widely agreed upon that our gut bacteria play a role in host immunity, nutrient absorption, digestion, metabolism, and other key drivers of health. Furthermore, certain microbial signatures and specific taxa have also been associated with the development of diseases, such as obesity; inflammatory bowel disease; and, indeed, colorectal cancer (CRC), which is the focus of this review. By extension, such taxa represent potential therapeutic targets. In particular, the emerging human pathogen Fusobacterium nucleatum represents an important agent in CRC development …

Anthropology Faculty Research

CrAssphage (cross-assembly phage) is a bacteriophage that was first discovered in human gut metagenomic data. CrAssphage belongs to a diverse family of crAss-like bacteriophages thought to infect gut commensal bacteria belonging to Bacteroides species. However, not much is known about the biogeography of crAssphage and whether certain strains are associated with specific human populations. In this study, we screened publicly available human gut metagenomic data from 3,341 samples for the presence of crAssphage sensu stricto (NC_024711.1). We found that crAssphage prevalence is low in traditional, hunter-gatherer populations, such as the Hadza from Tanzania and Matses from Peru, as compared to …

CRISPR–Cas is an anti-viral mechanism of prokaryotes that has been widely adopted for genome editing. To make CRISPR–Cas genome editing more controllable and safer to use, anti-CRISPR proteins have been recently exploited to prevent excessive/prolonged Cas nuclease cleavage. Anti-CRISPR (Acr) proteins are encoded by (pro)phages/(pro)viruses, and have the ability to inhibit their host’s CRISPR–Cas systems. We have built an online database AcrDB (http://bcb.unl.edu/AcrDB) by scanning ∼19 000 genomes of prokaryotes and viruses with AcrFinder, a recently developed AcrAca (Acr-associated regulator) operon prediction program. Proteins in Acr-Aca operons were further processed by two machine learning-based programs (AcRanker and PaCRISPR) to obtain …
