Coronavirus Food Assistance Program For Livestock Producers, Bradley Lubben

Extension Farm and Ranch Management News

United States Congress and the President have approved multiple phases of COVID-19 assistance to date including the $2.3 trillion CARES (Coronavirus Aid, Relief, and Economic Security) Act passed in March that provides financial support for agricultural producers as a small part of the overall relief.

While agricultural producers and agribusinesses are eligible for two programs administered through the Small Business Administration, including the Paycheck Protection Program (PPP) and Economic Injury Disaster Loans (EIDLs), the primary support for agriculture is coming from USDA through the Coronavirus Food Assistance Program (CFAP). The CARES Act provided $9.5 billion directly to the Secretary of …

Rapamycin Treatment Correlates Changes In Primary Cilia Expression With Cell Cycle Regulation In Epithelial Cells, Maha Jamal, Ane C.F. Nunes, Nosratola D. Vaziri, Ramani Ramchandran, Robert L. Bacallao, Andromeda M. Nauli, Surya M. Nauli

Pharmacy Faculty Articles and Research

Primary cilia are sensory organelles that regulate cell cycle and signaling pathways. In addition to its association with cancer, dysfunction of primary cilia is responsible for the pathogenesis of polycystic kidney disease (PKD) and other ciliopathies. Because the association between cilia formation or length and cell cycle or division is poorly understood, we here evaluated their correlation in this study. Using Spectral Karyotyping (SKY) technique, we showed that PKD and the cancer/tumorigenic epithelial cells PC3, DU145, and NL20-TA were associated with abnormal ploidy. We also showed that PKD and the cancer epithelia were highly proliferative. Importantly, the cancer epithelial cells …

Determining The Genetic Control Of Neural Tube Malformation Through Genetic Interactions With Idgf3, Elli N. Fox

Honors Projects

Genetic mutations disrupting human neural tube formation can lead to birth defects such as spina bifida and anencephaly. Defects can result in lack of neural tube closure in either the caudal (spina bifida) or cranial (anencephaly) regions. Little is known about the genes that cause these malformations. Researchers have been using the model organism Drosophila melanogaster in an attempt to determine genes responsible for neural tube malformations. Recently, an ortholog of human chitin-like protein, imaginal disc growth factor 3 (Idgf3), has been identified as important in the proper formation of Drosophila egg dorsal appendages. However, the molecular mechanism responsible for …

Reviewing The Potential Link Between Grain-Free Diets And Dilated Cardiomyopathy In Canines, Larissa J. Webster

University Honors Theses

Grain-free diets for dogs are becoming increasingly popular, but concerns are emerging following the FDA's recent investigation that there might be a link between grain-free diets and Dilated Cardiomyopathy (DCM) in dogs with no known genetic predisposition. Contrary to the majority of the public thought, dogs do nutritionally require grains, and there is rarely a medical reason to switch to a grain-free diet. Not all cases of DCM are linked to diet, and many dogs who are fed grain-free diets do not develop the disease; the extent of this issue therefore is not entirely known. This review aims to explore …

Determining The Link Between Advanced Glycation Endproducts (Ages), Feeding, And Metabolism, Lauren Wimer

Natural Sciences and Mathematics | Biological Sciences Master's Theses

Reactive a-dicarbonyls (a-DC’s), such as methylglyoxal (MGO), are unavoidable metabolites generated during glycolysis that accumulate with age and have been linked with chronic age-related metabolic diseases such as Diabetes Mellitus. Diabetes Mellitus is generally characterized by peripheral neuropathy and sustained hyperglycemia. Chronic hyperglycemia leads to an increase in glycolysis and a downstream increase in reactive a-DC’s. The human body has a natural method of detoxifying these a-DC’s. Glycolytic cells have enzymes which can detoxify a-DC’s, but if overwhelmed, a-DC’s can accumulate and react non-enzymatically with proteins, lipids and DNA to yield a group of molecules called advanced glycation end-products (AGEs). …

Swimming Pool Environment And Respiratory Health Issues Experienced By Masters Swimmers: Results From A Literature Review And Survey Of United States Masters Swimming Clubs, Jody C. Gan, Julia Snegg, William Harder

International Journal of Aquatic Research and Education

After three members of a Masters adult swim club died of lung cancer, both a literature review and survey were conducted with representatives from 746 United States Masters Swimming clubs to explore a possible relationship between swimming and cancers of the respiratory tract. Six other clubs reported known cancers of the respiratory tract among club members, but none of the other 740 clubs reported a similar cluster of lung cancer. More clubs reported cases of chronic respiratory infections and widespread complaints about air quality. While no studies exploring a relationship between swimming and lung cancer could be found in the …

The Partial Immersion Aquatic Approach Using Adjustable Weight Bearing To Improve Posture And Sitting Balance Adaptation For Children With Severe Cerebral Palsy, Niv Shelef

International Journal of Aquatic Research and Education

The innovative ‟Partial Immersion” Aquatic Therapy Approach was developed to enhance balance and posture during sitting adaptation for children with severe cerebral palsy who exhibit deficiency in those skills on land. Stable balance during sitting posture is one of the preconditions for hands function in activities of daily living. Aquatic skills learned during aquatic therapy were then transferred to a land environment. Therapy included the use of a treatment chair that enabled adjustable weight bearing in a series of 30 mm steps. A mixed-methods design employing a multiple case study approach (n=5) including quantitative and qualitative methods investigated the effectiveness …

The Evolving Management Of Aortic Valve Disease: Trends In The Utilization And Cost Of Savr, Tavr, And Medical Therapy, Andrew Goldsweig

Theses & Dissertations

Aortic stenosis (AS) and regurgitation (AR) may be treated with surgical aortic valve replacement (SAVR), transcatheter AVR (TAVR), or medical therapy (MT). Data are lacking regarding usage and cost of SAVR, TAVR, and MT for patients hospitalized with aortic valve disease. From the Nationwide Readmissions Database, we determined utilization and cost trends for SAVR, TAVR, and MT in patients with aortic valve disease admitted 2012-2016 for valve replacement, heart failure, unstable angina, non-ST-elevation myocardial infarction, or syncope. From 2012 through 2016, there was a 48.1% increase in the number of patients hospitalized for aortic valve disease annually. Overall, 19.9%, 6.7%, …

Baseline Health Assessment Of A Rural Delta Community, Sydney Mitchell

Honors Theses

The Lower Mississippi Delta is characterized by poverty, chronic health issues, health disparities, and food insecurity. The rural Delta communities are primarily African American, experiencing disproportionately higher rates of poverty, job loss, and chronic health problems. Historically, chronic health issues have persisted in these areas over time, including obesity, hypertension, and diabetes, which have only seemed to increase in this region. The food environment in this rural region tends to assist in the creation of the largely obesogenic population which, in turn, contributes to the increased prevalence of diabetes and hypertension and a lower quality of life. Many residents in …

Characterization Of A Plasmid-Based Dna Vaccine For Simian Immunodeficiency Virus, Priya Sanipara

Honors Theses

Described as one of the world’s worst pandemics, HIV (Human Immunodeficiency Virus) infects millions of people each year and is the cause for AIDS (Acquired Immunodeficiency Syndrome). Despite the development of vaccines for numerous infectious diseases such as polio, small pox, and influenza, a vaccine for HIV remains elusive due to the virus’s high mutation rate and ability to evade the immune system. HIV causes depletion of CD4+ lymphocytes, resulting in a weakened immune system. However, the development of a plasmid-based DNA vaccine approach may help revolutionize vaccine development for HIV due to its ability to confer cellular and humoral …

Influences Of Anti-Bd Bacteria On Amphibians And Their Microbiomes, Emme L. Schmidt

Honors Thesis

The fungal pathogen Batrochochytrium dendrobatidis (Bd) has been threatening amphibian populations across the globe. Recent work has discovered that bacteria isolated from certain populations of amphibians protect hosts from this pathogen. This project focuses on the anti-fungal mechanisms of Serratia marcescens, a species of bacteria isolated from a Costa Rican frog that dramatically inhibited Bd in culture. Wild-type and recombinant S. marcescens was introduced to the microbiomes of a live amphibian host, Acris blanchardi (Blanchard’s Cricket Frog) and then challenged with Bd to examine the protective effects of this bacteria. The experiment includes recombinant S. marcescens with …

The Role Of Central Ace2 And Nrf2 In Sympatho-Excitation: Responses To Central Angiotensin Ii, Anyun Ma

Theses & Dissertations

Sympatho-excitation is a key characteristic in cardiovascular diseases such as chronic heart failure (CHF) and primary Hypertension (HTN). Evidence suggests that increased sympathetic tone is closely related to activation of the Renin-Angiotensin-Aldosterone system (RAAS) in the central nervous system. An underlying mechanism for sympatho-excitation is thought to be oxidative stress resulting from Angiotensin II (AngII) type 1 receptor (AT1R) activation. Over the past several decades, pharmacological targeting of components of the RAAS have been used as standard therapy in CHF and HTN. However, additional therapeutic strategies are necessary to control these diseases. Oxidative stress is regulated, in part, by the …

Pilot Study Exploring The Effect Of Targeted Cox-2 Inhibition In Macrophages Responding To Neuronal Injury; Promoting Enhanced Axonal Regeneration, Alyssa Brauckmann

Electronic Theses and Dissertations

Celecoxib nanoemulsion (CXB-NE) has been developed as a macrophage targeted analgesics by Dr. Janjic and her team at Duquesne University, (Janjic et al, 2018; Liu et al, 2020; Saleem et al, 2019b; Vasudeva et al, 2014). The CXB-NE nanoemulsion carrying a Nonsteroidal Anti-inflammatory (NSAID) inhibitor of COX-2 activity result in a reduction in PGE2 expression in macrophages. Using CXB-NE in rats that have peripheral nerve injury constricting the sciatic nerve relieves hypersensitivity, a pain-like behavior. The treatment also decreases inflammation associated with this chronic constriction injury (Janjic et al, 2018; Saleem et al, 2019b; Stevens et al, 2019). In this …

The prevalence of airborne, waterborne, and vector-borne diseases have been found to be exacerbated as a result of climate change. In addition to this, the paper addresses the reemergence of eliminated diseases and ancient pathogens due to changing temperatures and weather patterns. Finally, the effect of these different conditions on national and international public health organizations and policies is analyzed, including projections on what can be …

The Current Neuroscientific Understanding Of Alzheimer's Disease, Rachel A. Brandes

Pursuit - The Journal of Undergraduate Research at The University of Tennessee

Alzheimer’s disease is a degenerative neurological illness characterized by the deterioration of brain regions implicated in memory and cognitive function. While researchers have yet to find a cure or effective treatment, they have gained a better understanding of its pathology and development. Through years of neuroscience research, scientists have discovered much of what happens in the brain during Alzheimer’s disease onset and how this causes its symptoms; many hypotheses regarding this aspect of the illness involve temporal lobe atrophy, neurofibrillary tangles, and amyloid plaques. Although Alzheimer’s disease affects millions of people every day, it seems that most are unaware of …

The Effect Of Staphylococcus Aureus Exposure On White-Tailed Deer Trabecular Bone Stiffness And Yield, Emily Brooke Long

Graduate Theses

Osteomyelitis is an infection of the bone or bone marrow caused by the infiltration of bacteria, resulting in destructive inflammation, bone necrosis and abnormal bone remolding. With a growing number of osteomyelitis diagnoses, many of which are linked to Staphylococcus aureus (S. aureus), it is imperative to understand the pathology of S. aureus in relation to bone to provide better diagnostics and patient care. While the cellular mechanisms of S. aureus and osteomyelitis have been studied, little information exists on the biomechanical effects of such infections. We postulated that exposure to S. aureus for 72 hours would significantly decrease both …

The Effects Of Farnesol, A Quorum Sensing Molecule From Candida Albicans, On Alcaligenes Faecalis, Savannah Hutson

Undergraduate Honors Theses

Quorum sensing molecules have become a recent focus of study to learn if and how they can be used, both on their own and in conjecture with current antimicrobial methods, as a means of bacterial control. One such quorum sensing molecule is the sesquiterpene alcohol, Farnesol, which is synthesized and released by the fungus, Candida albicans. In most in-vivo cases, our laboratory has shown that Alcaligenes faecalis overtakes C. albicans, preventing its growth. However, as a way to counteract this inhibitory effect, Farnesol may be one way that Candida has found to fight back. In this study, we …

Levels Of Parp1-Immunoreactivity In The Human Brain In Major Depressive Disorder, Aamir Shaikh

Undergraduate Honors Theses

MDD is a severe and debilitating disorder that is associated with a growing global economic burden due to reduced workplace productivity along with increased healthcare resource utilization. Furthermore, depression markedly enhances the risk for suicide, mortality that is especially worrisome given that 30% of depressed individuals have an inadequate response to current antidepressants. This inadequacy of antidepressants necessitates the discovery of a better understanding of the pathobiology of MDD. Most current antidepressants work through monoamine neurotransmitters, and their relative efficacy in depression led to the now dated monoamine-deficiency hypothesis. The limited usefulness of antidepressants has led to a reinvigorated search …

Gut Pathophysiology In Mouse Models Of Social Behavior Deficits, Kyla Scott

Undergraduate Honors Theses

Autism spectrum disorders (ASD) encompass neurodevelopment disorders characterized by atypical patterns of development that impact multiple areas of functioning beginning in early childhood. The etiology of ASD is unknown and there are currently no preventative treatment options. Gastrointestinal symptoms are commonly associated comorbidities. The microbiota-gut-brain axis is a multidirectional communication chain that connects the central and enteric nervous system that relates brain function to peripheral intestinal functions. Changes within this axis have been postulated in ASD. For example, the “leaky gut theory” proposes that chronic inflammation is linked to alterations in the bacterial profiles of the gut microbiome and subsequent …

Polycystic Ovary Syndrome, Subfertility And Vitamin D Deficiency, Arfa Azhar, Fatima Abid, Rehana Rehman

Department of Biological & Biomedical Sciences

Polycystic ovarian syndrome (PCOS) is the most common endocrine female disorder, affecting 4-18% women of reproductive age. The prevalence of PCOS in South Asian women, especially in Pakistani women, is much higher (52%) as compared to white population (20 - 25% in UK). In Pakistan, vitamin D status displays 31.2% vitamin D insufficiency, 53.5% vitamin D deficiency, and 15.3% normal vitamin D values. Vitamin D deficiency, though very common in the general population, is even more prevalent in PCOS patients, seen in approximately 67-85%, which further correlates to their related comorbidities. A lot of researches have to be directed to …

Animal Science Undergraduate Honors Theses

The purpose of this study was to evaluate the efficacy of extended-release eprinomectin against horn flies, face flies, and fecal egg counts of parasitic nematodes in crossbreed replacement beef heifers. Fifty-four heifers were randomly placed into three treatment groups (N=18 heifers/treatment). Group 1 was administered the labeled dosage of extended-release eprinomectin on day 0. Group 2 acted as the negative control. Group 3 received the anthelmintic injection once a quarter of the heifers in the group reached the threshold treatment level for horn flies (N=200 flies/animal; day 41). Nematode infections were measured via fecal egg counts while horn and face …

Functional Analysis Of A Critical Glycine (Glycine 12) In Beta-Type Connexins Of Human Skin, Rasheed Bailey

Biology Theses

At least five beta-type connexins are expressed in various layers of the skin (Cx26, Cx30, Cx30.3, Cx31, and Cx32) and all include a glycine residue at position 12. Glycine12 (G12) is located about halfway through the cytoplasmic amino terminus and has been the focus of several studies related to connexin diseases and gap junction channel structure. The importance of this residue is evident in the severity and diversity of diseases associated with amino acid substitutions at G12 including hereditary forms of skin disease, deafness and neuropathy. This study uses bioinformatic analysis in combination with mutational analysis and electrophysiology to better …

Serpinb1 Effects On Human Pancreatic Ductal Cells, Praneeth Goli

College of Arts & Sciences Senior Theses

Rebuilding or expanding the body’s ability to regulate blood glucose levels by restoring or increasing the body’s ability to produce insulin, long-term, would be a major advancement in diabetes (type-1 and type-2) treatment and could serve as a potential cure [1]. Therefore, the holy grail of diabetes treatment and cure research is to regenerate or increase the insulin producing cells in diabetic individuals (type-1 and type-2) [1, 2]. SerpinB1 has been implicated as a biomolecular signal that stimulates an increase in insulin cell mass in murine and zebrafish models that exhibit physiologically normal compensatory islet hyperplasia. In humans, SerpinB1 is …

Structural And Functional Characterization Of Mitochondria With Trna Mutations, Brooke Henry

Biological Sciences Undergraduate Honors Theses

Mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes (MELAS) is one of the most common disorders associated with mitochondrial tRNA mutations. One of the most common causes of MELAS is mutation in the MT-TL1 gene which codes for mitochondrial tRNA Leucine (UUR). Mutation in MT-TE gene, another mitochondrial gene which encodes for mitochondrial tRNA Glutamate (GAA/G), has been implicated in various mitochondrial related myopathies. It remains unclear how point mutations in these tRNA genes result in disease onset and progression. Here, we report an early comparative analysis of fibroblast cell lines derived from patients carrying two different tRNA mutations: m.3243A>G …
