Pathogenesis Of Dry Eye In Graft Versus Host Disease (Gvhd): Role Of Ocular Mucins And Conjunctival Fibrosis, Kiumars Shamloo
Pharmaceutical Sciences (PhD) Dissertations
Allogenic hematopoietic stem cell transplantation is a procedure that offers a possible cure for hematologic cancers and other hematologic disorders. Unfortunately, despite the increasing survival rate of patients, the quality of their life is adversely affected by the allogeneic bone marrow transplantation’s major side effect i.e Graft vs. Host Disease (GVHD). GVHD is a complex, multi-organ disease resulting from an immunological attack by donor engrafted immune cells to host organs, including the eye surface. Mostly based on the time of disease onset after transplantation, GVHD is divided into the acute and chronic phase. The eyes may be involved ...

Responses To Fine Particulate Matter (Pm2.5) Exposures In Two Wild-Type Zebrafish Strains, 2021 University of Mississippi
Responses To Fine Particulate Matter (Pm2.5) Exposures In Two Wild-Type Zebrafish Strains, Connor Necaise
Atmospheric fine particulate matter (PM2.5) exposure poses great health risks across the globe, causing both acute and chronic illnesses in humans. Therefore, a more complete understanding of the mechanisms in which PM2.5 induces these adverse health effects is urgently needed. Oxidative stress due to PAHs and other common components of PM2.5 is a proposed mechanism for its adverse health effects. However, little is known about the actual mechanisms of PM2.5 damage in humans. This study aimed to distinguish behavioral differences in two lines of zebrafish (AB & 5D) as a result of developmental ...
Particle Tracking Reveals Pelagic Red Crabs As Indicators Of Climate-Driven Range Expansion In The California Current, 2021 University of Rhode Island
Particle Tracking Reveals Pelagic Red Crabs As Indicators Of Climate-Driven Range Expansion In The California Current, Elizabeth Saraf
Senior Honors Projects
Since their first recorded occurrence in 1859, Pelagic Red Crabs (PRC; Pleuroncodes planipes) have experienced increased frequency of episodic mass stranding events in the Eastern Pacific Ocean. PRC’s are transported over 1,000 km northward of their central domain from the coast of central Baja California, Mexico. They have been reported by the thousands on the beaches of central and southern California. Their presence influences the surrounding ecosystem and commercial fisheries because they are nutritional prey items and large predators change their diet to incorporate PRC’s when they are available. Seasonal coastal currents and the California Undercurrent transport ...

Evaluation Of Weight Gain, Feed Intake, Feed Conversion And Oocyst Shedding Of Eimeria Maxima And Eimeria Acervulina In Broiler Chickens, Lauren Laverty
Poultry Science Undergraduate Honors Theses
The purpose of the present study was to evaluate the day and the time of sample collection of an
experimental challenge with Eimeria maxima (EM) and Eimeria acervulina (EA) in broiler chickens. One day old male Cobb-Vantress broiler chickens were randomly allocated to one of three groups with ten replicates (n=8 chickens/replicate). Chickens were placed in battery cages with a controlled age-appropriate environment: Group 1) Negative control (no challenge or treatment); 2) Challenge control (Eimeria challenge only); 3) Challenge + Salinomycin. Challenged chickens were orally gavaged with the mixed culture of EM/EA (10,000 sporulated EM containing 4 ...
The Evolution Of Mimicry; The Doublesex Gene, 2021 Southern Maine Community College
The Evolution Of Mimicry; The Doublesex Gene, Aisha Hill
Thinking Matters Symposium
Many butterfly species use mimicry in order to increase their chance of survival. In Batesian mimicry, non toxic butterflies mimic the wing patterns, colors, and shapes of another species that is toxic to predators. Swallowtail butterflies (Papilio polytes) are well-known Batesian mimics, and also display sexual dimorphism with distinct differences between the sexes. Sex limited mimicry is common. The female butterfly may mimic an inedible red-bodied swallowtail, such as the common rose (Pachliopta aristolochiae), or she may be non-mimetic. The male butterfly is non-mimetic. This is a review of recent research into the origin and evolution of gene(s) responsible ...
Validation Of A Novel Trpm8 Knockout Mouse Model, 2021 University of Southern Maine
Validation Of A Novel Trpm8 Knockout Mouse Model, Bilan Mohamed
Thinking Matters Symposium
Recent studies suggest that the use of thermoregulatory treatments that affect brown fat may help curb obesity. However it is unknown how these treatments may affect bone homeostasis. Our work has focused on the transient receptor potential melastatin (TRPM8) protein, which is responsible for detecting colder temperatures in sensory neurons. Previous work within the Motyl laboratory has found that Trpm8 plays a role in bone acquisition. Mice with a global deletion of the Trpm8 gene have reduced trabecular bone volume fraction due to reduced bone formation by osteoblasts. However, it is unclear whether sensory neuron or osteoblast-mediated expression of Trpm8 ...

The Graduate School Posters
Cancers are aggressive, evasive, and ruthless killers, claiming millions of lives every year. Cancers are heterogeneous and there is often no single, clearly defined problem as they harness and manipulate a multitude of fundamental mechanisms at the very essence of life. To investigate these mechanisms and vet potential interventive therapies, humanized mice offer a unique model as a prelude to the use of nanosecond pulse stimulation (NPS), a pulse power technology applying nanosecond duration, high electric field pulses, to ablate human tumors. Immunodeficient mouse strains, NSG and NSG-SGM3, were engrafted with human immune cells and human tumors, which would allow ...
A Comparison Of The Release Of Phosphorus By A Phytase Enzyme In Pigs Fed Diets Deficient Or Adequate In Phosphorus Content, Kristin M. Olsen, Stacie A. Gould, John F. Patience
Animal Science Publications
Previous research indicated that phytase may release less phosphorus (P) from phytate when it is evaluated using diets with P levels above requirement as compared with diets below requirement. The objectives of this experiment were to further test the hypothesis that the P release values determined for phytase are higher when pigs are fed diets that are deficient (DE) in P compared with when they are fed diets that are adequate (AD) in P, and that phytase will increase the digestibility of dry matter (DM), gross energy (GE), nitrogen (N), and calcium (Ca) independent of dietary P status. Twenty-four barrows ...
Morph- And Sex-Specific Differences In Corticosterone Of The Arizona Tiger Salamander (Ambystoma Mavortium Nebulosum), 2021 Murray State University
Morph- And Sex-Specific Differences In Corticosterone Of The Arizona Tiger Salamander (Ambystoma Mavortium Nebulosum), Megan Zerger
Life history morph, sex, and body condition are traits that may influence stress within salamander populations because of differences in physiology and environmental conditions. Given widespread declines and the effects chronic stress can have on amphibian health, it is important to understand within-population drivers of stress and how population level variation may influence population viability. Thus, the objective of our study was to assess how corticosterone varies within the Arizona tiger salamander (Ambystoma mavortium nebulosum) population at the Mexican Cut Nature Preserve. We used a non-invasive skin swabbing method to collect baseline and elevated corticosterone from paedomorph (aquatic morph; N ...

The objective of this study was to evaluate the impact of different management systems on the postnatal survival and growth of alpaca crias. The study was conducted during the alpaca calving season in the Peruvian Andes. Animals were fed on native pastures; during the day they went out to graze, but at night they were brought into a corral. A total of 150 alpaca singleton neonates were randomly assigned to one of three cria protection strategies immediately after consuming colostrum. The first group consisted of 50 crias who slept in an open-corral (OC) without shelter. The second group was comprised ...
How A Low-Cost Method For Cumulative Water-Sampling Shows Need For Improvement Of Legal Public-Contact Standards In The United States, Samuel Kessler
Grawemeyer Colloquium Papers
Across the world, it is estimated that 4.5 billion people live near water sources “impaired” for use or contact. Standards for human-interaction are established by international organizations such as the WHO, and legislative bodies from national to local levels with jurisdiction over the quality of our waterways to ensure public & environmental health. Standards are often assessed from “grab-samples” taken from a waterbody at a certain time, with a minimum number analyzed. Water-quality standards in the United States are enforced under the Clean Water Act (CWA) via the Environmental Protection Agency (EPA), applying to “waters of the United States” (WOTUS ...
Evaluating Anesthetic Protocols For Non-Human Primate Functional Neuroimaging, 2021 The University of Western Ontario
Evaluating Anesthetic Protocols For Non-Human Primate Functional Neuroimaging, Megha Verma
Electronic Thesis and Dissertation Repository
Functional magnetic resonance imaging (fMRI) is a non-invasive technique that can be used to measure a proxy of neural activity in vivo with high spatial specificity. One subject can be followed for a long period of time to assess changes in functional brain organization. However, fMRI is extremely sensitive to motion. The challenges of training non-human primates to reduce motion in an MRI scanner motivate the study of anesthesia which is commonly used to substitute for this training. In this thesis, I compare three different commonly used anesthetic protocols: isoflurane, propofol-fentanyl in combination, and fentanyl alone, to test which of ...
Molecular Mechanisms Regulating Optic Fissure Fusion During Zebrafish Eye Development, 2021 University of Kentucky
Molecular Mechanisms Regulating Optic Fissure Fusion During Zebrafish Eye Development, Megan Weaver
Theses and Dissertations--Biology
Vertebrate retinal development requires timely and precise fusion of the optic fissure. Failure of this event leads to congenital vision impairment in the form of coloboma. Recent studies have suggested hyaloid vasculature to be involved in OF fusion. In order to examine this link, we analyzed optic fissure fusion and hyaloid vasculogenesis in the zebrafish pax2a noi mutant line. We first determined that pax2a-/- embryos fail to accumulate F-actin in the optic fissure prior to basement membrane (BM) degradation. Furthermore, using 3D and live imaging we observed reduced OF hyaloid vascularization in pax2a-/- embryos. When examining the connection between pax2a ...
Mitochondrial Aspects Of Neuronal Pathology In Triple-Transgenic Alzheimer’S Disease Mice, 2021 West Virginia University
Mitochondrial Aspects Of Neuronal Pathology In Triple-Transgenic Alzheimer’S Disease Mice, John Zachary Cavendish
Graduate Theses, Dissertations, and Problem Reports
Alzheimer’s disease (AD) is a fatal, progressive neurodegenerative disease afflicting millions of people in the United States alone and is the only one of the top leading causes of morbidity and mortality with no effective disease-modifying therapies. It is the most common form of dementia, affecting one in three people over the age of 85. While the hallmarks of the disease include accumulation of beta-amyloid-based extracellular plaques and hyperphosphorylated tau-based intracellular neurofibrillary tangles, treatment strategies centered on removing or mitigating these components of AD have all failed in humans. Mitochondrial dysfunction has been increasingly recognized as an early and ...

Undergraduate Theses, Professional Papers, and Capstone Artifacts
The ability of healthcare providers to carefully consider all presentations of illness and injury, draw upon research and knowledge to develop a list of potential diagnoses, and further investigate systems expected to be impacted by these diagnoses, is crucial for accurate identification of a condition and subsequent treatment plans to improve the welfare of patients. In order to determine a possible cause for unusual anatomic changes in multiple regions of the male cadaver used in the University of Montana’s Anatomy and Physiology lab, we performed a differential diagnosis.This research is exempt from IRB approval because the individual is ...
Heart Health: Lifestyle Factors That Influence Cardiovascular Well-Being, 2021 Georgia Southern University
Heart Health: Lifestyle Factors That Influence Cardiovascular Well-Being, Holly K. Sawyer
Honors College Theses
Each year, one in every four deaths in the United States is a result of heart disease. As the leading cause of death among women and men from various ethnicities, heart disease may be overlooked when making everyday life decisions. As a group of genetic and behavioral conditions, heart disease is the number one killer of Americans. This may be due to the typical Western diet and daily life choices such as drinking alcohol or smoking tobacco. Heart diseases including atherosclerosis and coronary artery disease kill ten times more women than breast cancer (Lewis, et al., 2017). White men have ...
Soil Response Of Helicopter Liming In The Monongahela National Forest, 2021 West Virginia University
Soil Response Of Helicopter Liming In The Monongahela National Forest, Jarrett Douglas Fowler
Graduate Theses, Dissertations, and Problem Reports
Soils in the Monongahela National Forest (MNF) are acidic due to sandstone parent material, acid deposition, uptake of base cations by vegetation, and release of organic acids by organic matter (OM) decomposition. Increases in soil acidity have caused declines in forest health and changed species composition and nutrient status. Liming can neutralize soil acidity, but no large-scale liming projects have been done on acid forest soils in the USA. In anticipation of acquiring funding for a proposed liming project in the MNF, in 2007 and 2009 10 sites were selected to sample and analyze soils before lime was applied. In ...

The Physiological Interaction Of Sleep Deprivation And Zoledronate On Distal Femur Trabecular Thickness Of Ovariectomized Rats, Erin Nolte, Frank Frisch, Oliver Lopez
Health Sciences and Kinesiology Faculty Articles
Osteoporosis, a disease resulting in an increased risk of fracture due to compromised bone, affects 1 in 3 postmenopausal women. Discontinuities in the microarchitecture of bone, such as trabeculae, are seen in postmenopausal osteoporosis. This study aimed to evaluate how sleep deprivation affects the distal femur trabecular thickness of estrogen-deficient rats treated with Zoledronate. 29 ovariectomized Wistar female rats were separated into 4 groups. The control group (C) was housed in standard housing with a 12-hour light/dark cycle and was given an intravenous injection of 0.45 mL of 0.9% saline. The Zoledronate group (Z) were also housed ...
