Gut Bacteria And Their Influence On Metabolic Disorders, Stephanie Sorbara (Class Of 2015)

Biology Undergraduate Publications

The human gut microbial genome encodes for several metabolic processes that are not encoded for in the human genome. Through the study of metagenomics, mice, and human models, researchers have shown that changes in the gut bacterial composition can generate oxidative stress, release endotoxins, and induce lipogenesis. These pathways can disrupt normal metabolic function, resulting in obesity and other related metabolic disorders such as diabetes. Most of the health implications associated with obesity originate from the biological reactions carried out by the gut bacteria, which are strongly impacted by environmental factors. Probiotics, prebiotics and fecal transplantation are methods that can …

Angelman Syndrome, Stephanie Sorbara (Class Of 2015)

Biology Undergraduate Publications

Angelman Syndrome (AS) is a neurogenetic disorder that is classically characterized by excessive laughter and a happy demeanor. Aggression, sleep disorders and epilepsy are other phenotypes associated with this disorder as well. Both happy and aggressive demeanors have been expressed in five different consumers at The Kennedy Center, a site which offers programs and services to individuals with varying disabilities. Research proposes several different genetic mechanisms responsible for the development of AS, each of which impact the function of the UBE3A gene located in the 15q11-13 region on chromosome 15. Additionally, from an evolutionary perspective, Emotion Signaling Theory and Kinship …

Where There’S A Will: Can Highlighting Future Youth-Targeted Marketing Increase Support For Soda Taxes?, Sungjong Roh, Jonathon P. Schuldt

Research Collection Lee Kong Chian School Of Business

Objective: Amid concern about high rates of obesity and related diseases, the marketing of nutritionally poor foods to young people by the food industry has come under heavy criticism by public health advocates, who cite decades of youth-targeted marketing in arguing for reforms. In light of recent evidence that the same event evokes stronger emotional reactions when it occurs in the future versus the past, highlighting youth-targeted marketing that has yet to occur may evoke stronger reactions to such practices, and perhaps, greater support for related health policy initiatives. Method: In a between-subjects experiment, Web participants (N = 285) read …

The Depressing Of China's Economy: The Effect Of Rural---Urban Educational Inequality And Absence Of Land Market, Huayong Zhou

All Dissertations

This paper argues that too many workers were placed in traditional agricultural sector in China's economy after 1978. I investigate two factors which hindered the labor mobility from agricultural and non-agricultural sector: (1) human capital dierence between rural and urban workers brought by China's urban oriented public educational policy; (2) absence of land property rights and a well functioning land market. I incorporate those two frictions into a two-sector dynamic macro model. I calibrate the model and show that it provides a good fit for the evolution of GDP per-capita and employment share in agriculture in the Chinese economy. I …

Ahr-Related Activities In A Creosote-Adapted Population Of Adult Atlantic Killifish, Fundulus Heteroclitus, Two Decades Post-Epa Superfund Status, Josephine Wojdylo

All Dissertations

Atlantic killifish, Fundulus heteroclitus, have adapted to, or at least developed a level of resistance to creosote-based polycyclic aromatic hydrocarbons (PAHs) found at the Atlantic Wood (AW) superfund site in the southern branch of the Elizabeth River, VA USA. Historically, 90+% of the mummichogs at this site have hepatic lesions of varying severity, and 30+% of these fish have tumors of various origin. Many xenobiotics, including select PAHs found at the Atlantic Wood site, are ligands for the aryl hydrocarbon receptor (AhR), which is a promiscuous ligand-dependent transcription factor involved in developmental regulation, environmental sensing, and induction of a suite …

All Dissertations

This research studied the effect of transportation hazards on food product shelf life and package performance. Studies were conducted to determine the effect of package headspace volume, product viscosity and storage temperature on package integrity. Finally, accelerated shelf life testing (ASLT) was utilized to determine how simulated transportation hazards affected the shelf life of a specific food product. Institutional retort pouches containing either water or 5% starch solution were filled with varying amounts of headspace volume to determine if package headspace volume could aid in package performance during simulated engineering tests for packaged products. Fixed displacement vibration testing and compression …

Allosteric Regulation Of Bacterial And Fungal Xylulose 5-Phosphate/ Fructose 6-Phosphate Phosphoketolases (Xfps), Katie Glenn

All Dissertations

Acetate is excreted as a metabolic end product in many microbes. Acetate production has primarily been studied in bacteria and archaea but is known to occur in eukaryotic organisms as well. For example, acetate is one of the most abundant metabolites excreted by the fungal pathogen Cryptococcus neoformans during cryptococcosis suggesting that acetate production may be important during pathogenesis. One possible pathway for acetate production in C. neoformans involves the enzymes xylulose 5-phosphate/ fructose 6-phosphate phosphoketolase (Xfp), which can generate acetyl phosphate from either fructose 6-phosphate (F6P) or xylulose 5-phosphate (X5P), and acetate kinase (Ack), which can then convert acetyl …

Biology And Control Of The Bed Bug Cimex Lectularius L., Kevin Hinson

All Dissertations

After vanishing from the public eye for more than 50 years, bed bugs have resurged to become one of the most widely discussed and heavily researched insect pests in the westernized world. Our inability to prevent and successfully treat infestations has been the driving force behind this wave of research. I addressed gaps in our understanding of bed bugs by examining behavioral and life history characteristics, as well as insecticide application responses. I showed that natural-based products are generally ineffective against bed bugs, particularly when used as a residual treatment. I also found that bed bugs may be killed through …

The Role Of Claudins In Bone Metabolism, Fatima Zakariya Alshbool

Loma Linda University Electronic Theses, Dissertations & Projects

Osteoporosis, a major public health problem in the U.S., is characterized by low bone mass and structural deterioration of bone tissue. Since the imbalance between bone formation and bone resorption during bone remodeling has been documented to be a major factor in the pathogenesis of osteoporosis, it is crucial to identify novel genes and/or novel functions of known genes that regulate the formation and activity of bone forming osteoblasts and bone resorbing osteoclasts. To this end, recent evidence suggests a significant role for caudins (Cldns), which comprise a major group of tight junction proteins, in bone biology and development. This …

The Role Of The Principal In Improving Student Achievement In Low-Wealth Rural Elementary Schools, Mark D. Linton

Education Doctoral

Increased levels of accountability, mandated implementation of common core learning standards, and shrinking state funds for public schools have created unique challenges for principals seeking to increase student achievement levels. Schools located in states receiving Race to the Top (RTT) funds must measure teacher and principal growth by adopting evaluation systems based on student achievement measures. These issues are more significant for rural school administrators, who must pair these demands with the confining nature of small-town life; the multiple and sometimes conflicting tasks; and the lack of opportunity for professional camaraderie and growth. Although a large body of literature has …

Role Of Epistasis In Alzheimer's Disease Genetics, Mark T. Ebbert

Theses and Dissertations

Alzheimer's disease is a complex neurodegenerative disease whose basic etiology and genetic structure remains elusive, despite decades of intensive investigation. To date, the significant genetic markers identified have no obvious functional effects, and are unlikely to play a role in Alzheimer's disease etiology, themselves. These markers are likely linked to other genetic variations, rare or common. Regardless of what causal mutations are found, research has demonstrated that no single gene determines Alzheimer's disease development and progression. It is clear that Alzheimer's disease development and progression are based on a set of interactions between genes and environmental variables. This dissertation focuses …

Microvascular Function In Metabolically Healthy Groups Differing In Bmi And Waist Circumference, Nathan R. Earl

Theses and Dissertations

BACKGROUND: Microvascular dysfunction (MD: impaired performance of blood flow, tissue perfusion, blood pressure, etc.) is one of the earliest stages in the progression of various chronic diseases. OBJECTIVE: The aim of this study was to determine if a difference in microvascular function existed between two metabolically healthy groups that differed in BMI and waist circumference. DESIGN: This study employed a causal comparative design, with two groups: I) normal weight (n =14, BMI 28 kg/m2). METHODS: Microvascular function was assessed by measuring skin blood flow (SkBF) using laser Doppler flowmetry during postocclusive reactive hyperemia (PORH). The area under the SkBF time …

Targeted Sequencing Of Plant Genomes , Mark D. Huynh

Theses and Dissertations

Next-generation sequencing (NGS) has revolutionized the field of genetics by providing a means for fast and relatively affordable sequencing. With the advancement of NGS, whole- genome sequencing (WGS) has become more commonplace. However, sequencing an entire genome is still not cost effective or even beneficial in all cases. In studies that do not require a whole-genome survey, WGS yields lower sequencing depth and sequencing of uninformative loci. Targeted sequencing utilizes the speed and low cost of NGS while providing deeper coverage for desired loci. This thesis applies targeted sequencing to the genomes of two different, non-model plants, Artemisia tridentate (sagebrush) …

Hemoglobin A1c And The Diagnosis Of Diabetes And Prediabetes In Children And Adolescents, Jennifer Mcguire Hitt

Theses and Dissertations (ETD)

Although the American Diabetes Association (ADA) adopted the use of the glycated hemoglobin (A1C) test as a method of diabetes and prediabetes diagnosis, the ADA has not developed firm guidelines concerning the use of the A1C test in children and adolescents, as research has not validated thresholds in this group. Diabetes and prediabetes are diseases influenced by multiple factors, including race and ethnicity, age, vitamin D deficiency, and body mass index (BMI). The purpose of this study was to determine the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the A1C test compared to the gold …

Genetic And Chemical Dissection Of Bloodbrain Barrier Development In Zebrafish, Robyn Anne Umans

Theses and Dissertations (ETD)

The blood-brain barrier (BBB) maintains a homeostatic environment as well as prohibits the entrance of xenobiotics into the brain. Because of these qualities, drug delivery is a fundamental challenge for the treatment of many diseases of the central nervous system (CNS). Along with limiting the access of therapeutics into the brain, the BBB is also impaired in CNS pathologies. Understanding the molecular cues that are essential for healthy BBB development and integrity may reveal targets for drug delivery leading to decreased progression or possible treatment of many detrimental CNS diseases. While the central features of the BBB have been accepted, …

Determinants Of Livelihood Choices: An Empirical Analysis From Rural Bangladesh, S Rahman, S Akter

School of Geography, Earth and Environmental Sciences

The study identifies socio-economic determinants of livelihood choices of rural households in Bangladesh (4,195 households from 139 villages) by applying a multinomial logit model of occupational choice and a multivariate Tobit model that allows for jointness in decision making. Results reveal that households choose multiple livelihood options. A number of socio-economic factors and resources at the household level as well as the state of rural infrastructure significantly determine households’ livelihood choice. Overall, resource-rich and educated households engage in diversified livelihoods and rural infrastructure promotes such diversification. Female-headed households fail to participate in any of the livelihood categories and consequently earn …

Effects Of Water Column P-Availability And Litter Microbial Mediated Processes And Stoichiometry In Aquatic Systems, Ayla Smartt

Graduate Theses and Dissertations

Anthropogenic nutrient enrichment of aquatic ecosystems is prevalent and can have detrimental effects on biological condition. Many of these effects have been attributed directly or indirectly to changes in autotrophic processes. However, in detrital-based streams changes in course detrital stoichiometry and decomposition have been related to changes community structure and production at higher trophic levels highlighting the importance of considering the heterotrophic microbial responses to enrichment. Leaf litter stoichiometry, which is determined in part by the tree species source and the microbial communities that comprise the associated biofilm, is likely related to decomposition rates, but few studies examine these variables …

The Elimination Of Listeria Monocytogenes Biofilms From Stainless Steel Deli Meat Slicer Components By The Use Of Hurdle Technologies, Alexandria Wynne Mertz

Graduate Theses and Dissertations

Listeria monocytogenes growth is of the greatest concern amongst ready-to-eat foods. The United States Department of Agriculture's Food Safety and Inspection Services determined that deli luncheon meats pose the greatest risk of contamination from L. monocytogenes Industrial meat slicers have many removable parts that are connected with sealers and gaskets, which can become worn over time. These spaces cannot be cleaned adequately, therefore are susceptible to bacterial growth. Planktonic cells form biofilms in order to protect the cell from adverse conditions, like during routine cleaning and sanitation. Once a biofilm is formed, the bacteria are much more difficult to eradicate …

Changes In Monomeric And Polymeric Pigments During Chokeberry Juice Processing, Kail David Wilkes
