Too Cool For Camouflage?: The Effects Of Dive-Related Thermal Loss On Body Coloration In A Semi Aquatic Lizard, Lyra Lu, Alexandra Martin Jan 2025

Too Cool For Camouflage?: The Effects Of Dive-Related Thermal Loss On Body Coloration In A Semi Aquatic Lizard, Lyra Lu, Alexandra Martin

Research Days Posters 2025

Rapid body color change is well documented in animals, but the variety of environmental factors that induce this change are not fully understood. Anolis aquaticus is a tropical lizard with rapid body color changes and that uses colder-than-average refugia, namely diving underwater for extended periods, to flee from predators. Using underwater refugia causes these lizards to lose several degrees of body heat. This research tested the relationship of low body temperatures on body coloration. First, an observational study was conducted in the field of the correlation between body temperature and body color. Then, body temperature was experimentally reduced in the …


No Evidence For Sex-Specific Visual Acuity In Anolis Aquaticus, Samantha Garnsey, Janelle Talavera, Lindsey Swierk Jan 2025

No Evidence For Sex-Specific Visual Acuity In Anolis Aquaticus, Samantha Garnsey, Janelle Talavera, Lindsey Swierk

Research Days Posters 2025

Sex differences in sensory perception are widespread among animals, driven by sex-specific reproductive challenges. Males and females often exhibit different sensory abilities, such as in visual acuity; for example, in Heliconius butterflies, males exhibit greater visual acuity due to their mate-seeking behaviors. This study examined this idea in Anolis aquaticus, a semi-aquatic lizard with sexual dimorphism. Males court females using a colorful throat fan (dewlap), which females use to select mates. It is predicted that females will have greater visual acuity than males, given their reliance on visual signals for mate choice. A custom-built apparatus was used to test 45 …

Research Days Posters 2025

Biofilm dispersion is a survival mechanism where bacteria transition to a planktonic lifestyle. Dispersion is not characterized in Enterococcus faecalis (E. faecalis), a gut bacterium. In semi-batch cultures, E. faecalis formed steady state biofilms after 48 hours grown at 37°C in 10% Tryptic Soy Broth. Next, biofilm culture challenges with a 10-fold step increase in nutrients following 4 days of growth—prior to self-induced dispersion—resulted in statistically significant dispersion responses. To evaluate bile acids’ effect, dispersed cells were exposed to the primary and secondary bile acids cholic and lithocholic acid. Lithocholic acid retained biofilm growth during dispersion and thus may spur …

Womb To Waste: Climate Change’S Silent Attack On Reproductive Rights, Jenna Caron

Research Days Posters 2025

Women experience disproportionate impact on the effects of climate change—they’ve proven more likely to die in a climate disaster, rely on the resources that the climate crisis devastates, and to experience gender-based violence. This study examines the reproductive health within gender-based violence, positing that women residing in economically disadvantaged countries, identifying with historically marginalized communities, and/or possessing harmful medical predispositions, experience more severe maternal and fetal health outcomes. By examining data and academic literature through biomedical and biological studies of sexual violence, birth rates, climate-related stressors, and harmful pollutants, this study concludes a strong connection between climate-related weather conditions and …

Research Days Posters 2025

Psychological resilience is associated with numerous positive mental health outcomes. This study examines the correlation between diet quality and psychological resilience. An anonymous survey was administered digitally and was shared by group members through social media platforms and flyers posted throughout the Binghamton University campus. The survey included questions regarding demographic and lifestyle information, nutrition habits, psychological resilience and flexibility, and recent experiences with emotions. A healthy balance of whole grains (p<0.01), vegetables (p<0.05), meat (p<0.05), and carbohydrates (p<0.05) is associated with increased psychological resilience. Comparatively, legumes (p<0.05) and caffeine (p<0.05) consumption are associated with lower reported psychological resilience. These findings emphasize the importance of improving diet quality for the overall psychological health of people as a simple and non-pharmaceutical way for all people to improve their psychological health, making it an accessible route for multiple populations.


Like A Natural Woman: Why We Still Need Ecofeminism, Emma Dean-Stahl Jan 2025

Like A Natural Woman: Why We Still Need Ecofeminism, Emma Dean-Stahl

Research Days Posters 2025

In the last half-century, ecofeminism has emerged and expanded as a radical theory examining the connection between the oppression of women and the destruction of the environment. This theory denounces the shared patriarchal exploitation of women and nature by promoting holism and interdependence among all living things. Overtime, however, ecofeminist thought splintered into two distinct variants: cultural and radical. Cultural ecofeminism in particular, which embraces the biological and spiritual tie between women and nature as opposed to rejecting it, has faced many critiques about its apolitical, essentialist, and mystical philosophical approach. This project attempts to reinterpret and defend cultural ecofeminism …

“One, Two, Three, Four, We Don’T Want Your Fucking War”: The Student Protest Movements At Columbia University And Kent State University During The War In Vietnam, Eric Kappaz

Master's Theses and Doctoral Dissertations

The comparative study of student protests at drastically different universities and the success ofthose protests is significantly lacking from the historical record. The Vietnam era was a pivotal turning point in American university life, during which students across the country pushed for changes not only to the institutions of higher learning but also to the country as a whole. This historical comparative analysis utilizes significant primary source documentation to analyze how students and universities at the time dealt with the changes that were occurring in the university structure and the intrusion on university operations by outside actors, specifically the federal …

Results. Strong convergent validity was found between PediaTrac and ASQ-3 domains at both time points. MOT at 9-months …


Genetic Privacy, Ifeoma Ajunwa, Forrest Briscoe Jan 2025

Genetic Privacy, Ifeoma Ajunwa, Forrest Briscoe

Indiana Law Journal

The last decade has brought many technological advances to genetic testing. Increasingly, genetic testing, which was previously reserved for clinical or medical settings, has made its way to other spaces. Most significantly, we are now seeing the re-introduction of genetic testing to the workplace. Although the Genetic Information Nondiscrimination Act (GINA), which became law in 2009, would seemingly prohibit genetic testing in the workplace, genetic testing, as part of workplace wellness programs, is lawful under the aegis of the Affordable Care Act (ACA). This poses a threat to genetic privacy in the workplace. While some, like the actor Angelina Jolie, …

Reports

EXECUTIVE SUMMARY

• The Arctic Ocean region stands at the forefront of global environmental transformation, serving as a harbinger of climate change and a frontier for emergent geopolitical and economic interests.

• The Arctic region's economic potential, particularly in shipping and resource extraction, appears to offer shorter trade routes, reduced fuel consumption, and increased access to high-value resources. However, this analysis largely ignores the complex geo-physical, environmental and geographical limitations of the region.

• The fragility of Arctic Ocean ecosystems – characterized by slow ecological recovery, specialised biodiversity, and extreme environmental conditions – renders them especially vulnerable to anthropogenic disturbances. …


Toward Biocompatible Assessment Of N-15 Hyperpolarized Metronidazole For Hypoxia Sensing, Faisal Asif Jan 2025

Toward Biocompatible Assessment Of N-15 Hyperpolarized Metronidazole For Hypoxia Sensing, Faisal Asif

Wayne State University Theses

Recent advances in hyperpolarization, particularly Signal Amplification by Reversible Exchange (SABRE), have enhanced molecular magnetic resonance imaging (MRI) for in vivo applications. This study investigates [15N3]metronidazole, a tri-nitrogen-labeled derivative of an FDA-approved antibiotic, as a hypoxia-sensitive imaging agent. Under hypoxic conditions, the nitroimidazole group undergoes stepwise reduction to an amino group, inducing significant 15N chemical shift changes (30–600 ppm). We aim to develop an iridium catalyst-free, biocompatible hyperpolarized (HP) [15N3]metronidazole formulation exhibiting robust polarization (up to 15%) and extended T1 lifetimes (~10 min). Three specific objectives guide this work: (1) formulation of a HP injectable with enhanced 15N detection, (2) …

Durable Oxyfluoride Waste Forms For Salt Wastes From Molten Salt Reactors, Alevtina A. Maksimova, Jake W. Amoroso, Matthew Page, Gregory Morrison, Hans Conrad Zur Loye

Faculty Publications

Molten salt reactors (MSRs) are promising technology to replace traditional light and heavy water reactors in the near future. Waste management for MSRs, however, remains a pressing concern that needs to be resolved prior to realizing deployment of MSRs. Specifically, the generated salt waste needs to be safely sequestered, a task made difficult by the high solubility of the salt waste that can cause the release of radionuclides into the environment. This work demonstrates a new approach to immobilize multiple fluoride salts into a single waste form by converting highly-soluble fluorides to durable and stable oxyfluorides. Notably, we report a …

Pharmacy

Given the pivotal role of CDK4/6 deregulation in the pathogenesis of various malignancies, CDK4/6 inhibitors have been incorporated into cancer treatment protocols. Beyond their antiproliferative effects, these inhibitors exhibit prominent immunomodulatory properties. Preclinical data indicated that CDK4/6 inhibitors enhance the tumor cell antigen presentation capacity and restrict the proliferation of immunosuppressive regulatory T-cells. Furthermore, studies showed that CDK4/6 inhibitors could enhance the development of memory T-cell in vivo in melanoma mouse models and in the clinical setting in breast cancer (BC) patients. In silico analysis identified 225 protein targets for CDK4/6 inhibitors involved in 57 immune-related pathways which further supported …

All addictive substances directly or indirectly interact with the dopamine reward system to alter the brain’s dopamine receptor activities. It is essential for a truly effective addiction medication to attenuate substance reward and normalize the brain’s physiological functions. Conventional pharmacological intervention approaches to the treatment of substance addiction usually aim to develop and deliver a potential therapeutic agent to the brain to directly block or decrease actions of the substance or its therapeutic target in the brain. However, it is a grand challenge to attenuate the substance reward without affecting the normal physiological functions of brain receptors or transporters. Here, …

Kappa opioid receptor (KOR) agonists have well-established antinociceptive effects. However, many KOR agonists have negative side effects, which limit their therapeutic potential. Some researchers have suggested that the development of biased agonists that preferentially stimulate KOR G-protein pathways over β-arrestin pathways may yield drugs with fewer adverse side effects. This was investigated in the current study. We describe the synthesis and characterization of three U50,488 analogues, 1, 2, and 3. We evaluated the acute and chronic antinociceptive effects of these compounds in mice using the warm-water tail flick assay and in a paclitaxel-induced neuropathic pain model. Side …
