Stage Of Estrous Cycle Influences Behavior After Social Stress, Alexander Jonah Rodriguez
Honors Thesis
Since women are almost twice as likely to develop major depression compared to men, research into this and other potentially debilitating mood disorders using behavioral studies should involve females despite hormonal, physiological, and potential behavior changes due to reproductive cyclicity. Until recently, most studies exclusively used males, thus limiting results of previous research to half of the population. Using adult female C57BL/6N mice as model organisms, we exposed them to novel forms of social stress across five days which encompassed the four-day estrous cycle to determine if the stages of the estrous cycle had an impact on behavior when ...

Currently, 5.8 million Americans are living with Alzheimer’s disease (AD), which is a degenerative brain disease. It is currently the sixth-leading cause of death in the United States (Alzheimer’s Association, 2019). AD also possesses a financial burned on the United States, estimated to cost $290 billion in 2019. Sufferers of AD insidiously lose their memory, personality, and judgment abilities until there are no longer recognizable by their loved ones. Currently, the best chance suffers of AD have is to catch the disease early on to slow its effects. This is due to the fact that treatment can ...

Perivascular Adipose Tissue In Relation To Diet, Thermogenesis And Cardiovascular Health, Ginger Paquette, Caitlin Stieber, Ashely Soucy, Benjamin Tero, Lucy Liaw
Thinking Matters Symposium
Adipose tissue is a diverse and crucial component to vascular health due to its role in energy storage and heat production. The primary function of white adipose tissue (WAT) is energy storage while the function of mitochondria-rich brown adipose tissue (BAT) is heat production. Perivascular adipose tissue (PVAT), which surrounds blood vessels, contains both WAT and BAT adipocytes. Dietary calorie restriction is associated with increased lifespan with decreased adiposity. Increased prevalence of WAT-like PVAT, due to high-fat diets and obesity, leads to increased metabolic disfunction and cardiovascular-disease. We used a calorie-restriction model in C57BL6/J mice to test the hypothesis ...

Effect Of Temperature On Questing Activity Of Ixodes Scapularis In A Laboratory Setting, Molly Meagher
Thinking Matters Symposium
Understanding deer tick (Ixodes scapularis) behavior is increasingly important due to the species’ northerly range expansion, and consequently, increased human contact. Deer ticks are a major public health concern, as they are the primary vector of Lyme disease and other serious diseases. Differences in questing behavior are of considerable interest as fluctuating weather due to climate change effect the species’ range expansion and time spent questing. Although previous research has examined temperature preferences of tick behavior, there are conflicting reports about direct effects on questing activity. Therefore, I addressed the relationship between temperature and questing behavior of adult deer ticks ...

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 ...

Interrogating The Functions Of The Histone H2a Repression Domain In Relation To Cell-Cycle Progression In Saccharomyces Cerevisiae, Taylor Nattress
Senior Scholars Day
In eukaryotic cells, DNA is wrapped around histone proteins to form the basic repeating unit of chromatin, the nucleosome core particle. Most nucleosomes consist of two copies each of histones: H2A and H2B in a heterodimer and histones H3 and H4 in a heterotetramer. Because of their intimate association with DNA, histones regulate all DNA-templated processes such as transcription, DNA replication, and DNA damage response and repair. Several studies have illustrated the importance of a small portion of the histone H2A amino terminal domain which regulates global transcription. This domain is responsible for the repression of ~4% of the yeast ...

The Effect Of A Single Dose Of Beetroot Juice On Speed, Strength, And Power In Healthy Recreationally Active Females., Maya A. Hammer, Ryan Kenney, Katie Price, Chandler Riley, Alyssa Riley, Courtney Merrill, Adam Pennell, Rachel Tan
Seaver College Research And Scholarly Achievement Symposium
Nitrate-rich beetroot juice (BR) improves muscle contraction which is relevant for intense intermittent-type sports. However, few studies have examined the effect of BR ingestion on performance using sport-specific exercise protocols. Moreover, there is a scarcity of research that include female participants which limits real world application given that females potentially have different responses to BR ingestion. The purpose of the present study was to examine the effect of BR supplementation on speed, acceleration, strength and power before and after fatigue in females. In a double-blind, randomized crossover design, 15 recreationally active females consumed BR and nitrate-depleted placebo juice (PL) ~2 ...

The Effects Of Nitrate-Rich Beetroot Juice Supplementation On Nonverbal Executive Function In Healthy Recreationally Active Females, Chandler F. Riley, Alyssa Riley, Maya A. Hammer, Ryan Kenney, Katie Price, Courtney Merrill, Adam Pennell, Rachel Tan
Seaver College Research And Scholarly Achievement Symposium
Nitrate-rich beetroot juice (BR) supplementation has been reported to preserve executive function (i.e. decision making and reaction time) before and after a simulated soccer match in recreationally active males, which may be due to enhanced cerebral blood flow. However, the literature examining the physiological response following BR ingestion in females is scarce, which hampers the extrapolation of results since physiological sex-differences may exist. Therefore, the purpose of this study was to assess if BR ingestion influenced executive function in an unfatigued and fatigued state in healthy recreationally active females. In a double-blind, randomized crossover design, 20 females consumed 140 ...

The Effect Of Changing Substrate On Arctic Aquatic Invertebrates Abundance, Tom Dolman
Michael D. Wilson Symposium
Climate change is directly affecting tundra ecosystems in northern regions, and warming temperatures have caused discontinuous permafrost and thawing sediments across the region. This project investigates how increasing erosion and the foraging patterns of migratory snow geese may degrade habitat for aquatic invertebrates in the upper Mast River, located in Wapusk National Park, Manitoba, Canada. In the past two decades, many of the important species of aquatic invertebrates have shown declines. Declining invertebrate populations are predicted to affect aquatic ecosystems and decrease the resources available to shorebirds and waterfowl, which breed and migrate through this area.

Toxic Effect Of Crotalus Adamanteus Acidic Phospholipase A2 On Mcf-7 Cell Line, Daniel J. Petra
Honors Thesis
We are investigating the effect of Crotalus adamanteus acidic phospholipase A2 on MCF-7 cells using the MTS assay. Understanding these interactions and isolated effects is critical to developing new ways to treat envenomation. By understanding the effects of individual toxins within a whole venom, we are set to better understand the effects of the whole venom and investigate synergistic actions between venom toxins. In this paper, we are quantifying the amount of MCF-7 cell death caused by Crotalus adamanteus phospholipase A2 on MCF-7 using the MTS assay. Analysis of the amount of cells death caused by the phospholipase ...

Morph- And Sex-Specific Differences In Corticosterone Of The Arizona Tiger Salamander (Ambystoma Mavortium Nebulosum), Megan Zerger
Scholars Week
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 ...

Functional Influence Of 14-3-3 (Ywha) Proteins In Mammals, Elizabeth Barley, Santanu De
Mako: NSU Undergraduate Student Journal
The 14-3-3 (YWHA) proteins are homologous, ubiquitous, and conserved in most organisms ranging from plants to animals and play important roles in regulating key cellular events such as cell signaling, development, apoptosis, etc. These proteins consist of seven isoforms in mammals, termed under Greek alphabetization: beta (β), gamma (γ), epsilon (ε), eta (η), tau/theta (τ), sigma (σ), and zeta (ζ). Each of these isoforms can interact with a plethora of binding partners and has been shown to serve a distinct role in molecular crosstalk, biological processes, and disease susceptibility. Protein 14-3-3 isoforms are scaffolding proteins capable of forming homodimers ...

Substance use disorders (SUD) account for a large number of mental health diagnosis in the United States and around the world. Approximately 13.6 million adults 26 or older and 5.1 million young adults (ages 18-24) battled with a SUD in 2017. Alcohol Use Disorder (AUD) alone effects nearly 6% of the adult population within the United States. This creates a substantial burden on the individual, with alcohol being the third-leading cause of preventable death in the United States. Few treatments for AUD exist, with no new FDA-approved therapeutic treatments within the last 15 years. Additionally, the limited treatments ...

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 ...

International Journal of Speleology
Although molecular approaches can identify members of microbial communities in the environment, genomic information does not necessarily correlate with environmental phenotype. Understanding functional roles can be done by cultivating representative species, yet the culturablility of bacteria from caves remains low, at 0.02%, limiting our understanding of microbial community interactions and processes. We have investigated several factors influencing culturability of bacteria from a single sample location in Maxwelton Sink Cave, WV, USA. Extended incubation of inoculated plates showed a significant increase in colony counts from two to four weeks, indicating that extended incubations increase culturability. There were no significant differences ...

An Approach For The In-Vivo Characterization Of Brain And Heart Inflammation In Duchenne Muscular Dystrophy, Joanne Tang
Electronic Thesis and Dissertation Repository
Duchenne muscular dystrophy (DMD) is a neuromuscular disorder caused by dystrophin loss—notably within muscles and CNS neurons. DMD presents as cognitive weakness, progressive skeletal and cardiac muscle degeneration until pre-mature death from cardiac or respiratory failure. Innovative therapies improved life expectancy, but this is accompanied by increased late-onset heart failure and emergent cognitive degeneration. Thus, there is an increasing need to both better understand and track disease pathophysiology in the dystrophic heart and brain prior to onset of severe degenerative symptoms. Chronic inflammation is strongly associated with skeletal and cardiac muscle degeneration, however chronic neuroinflammation’s role is largely ...
