Potential Role Of Exercise Induced Extracellular Vesicles In Prostate Cancer Suppression, Ying Zhang, Jin-Soo Kim, Tain-Zhen Wang, Robert U. Newton, Daniel A. Galvao, Robert A. Gardiner, Michelle M. Hill, Dennis Taaffe

Research outputs 2014 to 2021

Physical exercise is increasingly recognized as a valuable treatment strategy in managing prostate cancer, not only enhancing supportive care but potentially influencing disease outcomes. However, there are limited studies investigating mechanisms of the tumor-suppressive effect of exercise. Recently, extracellular vesicles (EVs) have been recognized as a therapeutic target for cancer as tumor-derived EVs have the potential to promote metastatic capacity by transferring oncogenic proteins, integrins, and microRNAs to other cells and EVs are also involved in developing drug resistance. Skeletal muscle has been identified as an endocrine organ, releasing EVs into the circulation, and levels of EV-containing factors have been …

Short Word-Length Entering Compressive Sensing Domain: Improved Energy Efficiency In Wireless Sensor Networks, Nuha A. S. Alwan, Zahir M. Hussain

Research outputs 2014 to 2021

This work combines compressive sensing and short word-length techniques to achieve localization and target tracking in wireless sensor networks with energy-efficient communication between the network anchors and the fusion center. Gradient descent localization is performed using time-of-arrival (TOA) data which are indicative of the distance between anchors and the target thereby achieving range-based localization. The short word-length techniques considered are delta modulation and sigma-delta modulation. The energy efficiency is due to the reduction of the data volume transmitted from anchors to the fusion center by employing any of the two delta modulation variants with compressive sensing techniques. Delta modulation allows …

Risk Factors For Gut Dysbiosis In Early Life, Kimberley Parkin, Claus T. Christophersen, Valerie Verhasselt, Matthew N. Cooper, David Martino

Research outputs 2014 to 2021

Dysbiosis refers to a reduction in microbial diversity, combined with a loss of beneficial taxa, and an increase in pathogenic microorganisms. Dysbiosis of the intestinal microbiota can have a substantial effect on the nervous and immune systems, contributing to the onset of several inflammatory diseases. Epidemiological studies provided insight in how changes in the living environment have contributed to an overall loss of diversity and key taxa in the gut microbiome, coinciding with increased reports of atopy and allergic diseases. The gut microbiome begins development at birth, with major transition periods occurring around the commencement of breastfeeding, and the introduction …

Monolayer Sorption Isotherm Model For Surface Tension Of Aqueous Surfactant Solutions Containing Electrolytes And Organic Mixtures, Kaiser Ahmed Bhuiyan

Theses and Dissertations

The surface tensions and compositions of aqueous aerosols dictate surface-mediated processes, especially the growth of aerosol particles into cloud nuclei and interfacial chemical reactions. Surface tension is also an indirect proxy for the partitioning of organics to the surface due to enhanced organic activity, driven by a reduction in solubility. Model predictions are generally not available for most surfactant-laden multi-component aqueous solutions, despite the importance of surface tension. Our recent multi-component surface tension model uses competitive adsorption at the interface, but these results are not consistent with salting out.1 We have now applied these techniques to surfactants in pure water …

Narratological Limitations Of Telling Trauma: A Case Study Of Lorena Bobbitt And Sexual Assault, Brittney Christy

Theses and Dissertations

There are many barriers that women face when they tell their stories of sexual assault, namely—that they will not be believed. A number of factors hinder believability, many of them related to the broader relationship that narrative plays in our lives. Narrative expectation, cultivated by the texts we consume, shapes what we find believable or “tellable” in the words of scholar Amy Shuman. Difficult narratives are often rendered “untellable” because they contain unfamiliar patterns or because they fall outside recognizable frameworks of understanding. Sexual assault narratives are rendered untellable for many reasons, including social misunderstanding of the problem and the …

Building Active Intersectional Allyship In Middle School Youth, Maura Ferguson

Theses and Dissertations

This thesis explores how an understanding of concepts of the framework of intersectionality may build resilience and increase ability for middle schoolers to learn to be active, effective allies for one another. Allyship is discussed as a necessary skill to learn and not a label one can self-select. A literature review is presented with a specific focus on intersectionality; trauma, resilience, and long-term impact of childhood trauma; and active allyship. These concepts are then framed through a social work lens, focusing on micro, mezzo, and macro levels. As human connection is critical for psychosocial health, this thesis then presents a …

Receiver operating characteristic …

Eating Disorder Symptoms On Female Collegiate-Level Athletes And Non-Athletes, Kennedy Victoria Kidd

Theses and Dissertations

In previous research, it found that the risk of developing an eating disorder (ED) is much higher in females compared to males (Dunca, Ziobrowski & Nicol, 2017; Raevuori, Keski-Rahkonen, & Hoek, 2014; Lewinsohn, Seeley, Moerk, & Striegel-Moore, 2002). Similarly, research has shown that the prevalence of EDs is much higher in female athletes compared to male athletes (Johnson, Powers, & Dick, 1999). Despite the risk of developing an ED being higher in females, research has not provided a strong understanding of the prevalence of EDs comparing female student-athletes and female student non-athletes. There is research that shows that athletes may …

Effects Of Hiv-1 Gp120 On Intracellular Levels Of Iron And Reactive Oxygen Species: Implications For Lysosomal Stress, Koffi L. Lakpa

Theses and Dissertations

Approximately 1.2 million people in the U.S.A are living with HIV-1. The development of antiretroviral therapeutics has increased the life expectancy of people living with HIV-1 (PLWH). Yet, there is a growing concern for aging HIV-positive individuals because about 50% of PLWH develop neurological impairments, termed HIV-associated neurocognitive disorders (HAND). There are no treatments for HAND and the mechanisms underlying its pathogenesis remain unclear. Several factors are implicated in HAND pathogenesis, such as HIV-1 coat protein gp120, endolysosome and mitochondrial dysfunction, and elevated levels of reactive oxygen species (ROS). Endolysosomes are acidic organelles that contain readily releasable stores of cations, …

Girls In Stem, Carrie Leopold

Theses and Dissertations

The recruitment and retention of women in STEM have historically been a struggle. Several causes, such as social factors, stereotypes, and classroom environments, all play a role (Blackburn, 2017). Recruitment efforts are often focused on middle school students. Nevertheless, research shows that children as young as kindergarten already have a preconceived notion about math (Ceci et al., 2014), such as it is too difficult or girls are not 'smart enough' to be successful. By the time some of these girls enter middle school, it can be challenging to change their mindset. Therefore, we need to focus not only on the …

Test Of A Partial Sexual Minority Stress Model With Bisexual Adolescents, Marisa Mango

Theses and Dissertations

Research conducted on sexual minority stress for adolescents has contributed to bisexual invisibility by collectively sampling and analyzing data from lesbian, gay, and bisexual populations, despite recent studies acknowledging statistical differences between bisexual and lesbian/gay experiences (Conlin et al., 2017; Frost et al., 2015; Mason & Lewis, 2016; Mohr & Sarno, 2016). We examined the temporal relations within Meyers (2003) Sexual Minority Stress model of sexual minority processes related to proximal and distal stressors in a sample of 306 bisexual adolescents. They completed measures of sexual minority stress, LGB specific coping, anxiety, and depression. Using path analytic analyses, the findings …

An Examination Of Rural Help-Seeking Behaviors Related To Sexual Violence And Mental Health And Well-Being Outcomes, Dacia Kay Oberhelman

Theses and Dissertations

Those who experience sexual violence face numerous barriers in gaining access to resources. Additionally, choosing to seek help following an unwanted sexual experience is a difficult decision that is impacted by attitudes, subjective norms, and perceived behavioral control. The Theory of Planned Behavior addresses how these variables can help explain one’s intent to seek help following an unwanted sexual experience. Seeking help following an unwanted sexual experience has also been suggested to be increasingly difficult for those in rural communities due to additional barriers such as: fear of community and family backlash, lack of anonymity, fear of perpetrator(s) discovering services …
