Title: Biological Benefit of the mCAT.
Creator: Frydman, Sylvia, Yousefzadeh, Matt, Niedernhofer, Laura, Dawson-Scully, Ken
Abstract/Description: Aging is associated with chronic diseases and is attributed to increased morbidity, mortality, and healthcare costs globally. Controversy exists over the root cause(s) of aging, nonetheless, extensive research links increased oxidants and reduced antioxidant buffering capacity with aging. The free radical theory of aging posits that the toxic build-up of free radicals and reactive oxygen species (ROS), promotes oxidative stress and enhances aging.

Show moreAging is associated with chronic diseases and is attributed to increased morbidity, mortality, and healthcare costs globally. Controversy exists over the root cause(s) of aging, nonetheless, extensive research links increased oxidants and reduced antioxidant buffering capacity with aging. The free radical theory of aging posits that the toxic build-up of free radicals and reactive oxygen species (ROS), promotes oxidative stress and enhances aging. Investigations involving the effect of mitochondrial-targeted catalase, have proven to be beneficial in reducing ROS and increasing lifespan in naturally aged mice. My project involves investigating the biological benefit of the mCAT transgene and rescue of age-related functional decline in progeroid Ercc1-/∆ mice, an accelerated mouse model of aging. mCAT expression was shown to be largely restricted to the brain, heart, and muscle of mice. mCAT+/-;Ercc1-/∆ mice showed improvements in behavioral tests and health evaluations relative to controls.

Title: Development and Optimization of AlphaScreen Assay for Discovery of Galectin-1/-3 Inhibitors.
Creator: Rivero, Yaima, Fitzgerald, Forrest, Cudic, Mare
Abstract/Description: Galectin-1 is a beta-galactoside-binding protein implicated in regulating apoptosis, cell proliferation and cell differentiation. The objective of our research was to develop and optimize an assay format for the discovery of new inhibitors of galectin-1 using AlphaScreen technology in a competitive binding configuration. Our efforts were hampered by the weak binding affinities of galectin-1 for its binding ligands (μM range). Consequently, the AlphaScreen assay could not have been developed...
Show moreGalectin-1 is a beta-galactoside-binding protein implicated in regulating apoptosis, cell proliferation and cell differentiation. The objective of our research was to develop and optimize an assay format for the discovery of new inhibitors of galectin-1 using AlphaScreen technology in a competitive binding configuration. Our efforts were hampered by the weak binding affinities of galectin-1 for its binding ligands (μM range). Consequently, the AlphaScreen assay could not have been developed at the level that would satisfy the guidelines from the National Chemical Genomics Center. Nevertheless, we have optimized the AlphaScreen assay for galectin-3, another member of galectin family, and screened an FDA approved oncology drug library (n = 101) from the NIH. We identified three possible inhibitors of galectin-3. These compounds showed a positive activity in dose response experiments: bleomycin (IC50 = 25.7 nM), cisplatin (IC50 = 127 nM), and mitoxantrone HCl (IC50 = 662 nM).

Show moreOver 40 million people in the United States are living in poverty today. The effects of living in disadvantaged circumstances increases the individual’s likelihood of experiencing persistent anxiety, which can lead to chronic health conditions. Studies have associated persistent anxiety with cardiovascular compromise as a result of decreased levels of heart rate variability (HRV). The purpose of this study is to explore the relationship between anxiety and heart rate variability in parents or guardians of children in Head Start, a federally funded program for families with low-incomes. A descriptive correlational design comparing the scores on the PROMIS anxiety tool with HRV as measured by the emWave biometric instrument will be used. The sample consists of 32 participants. Data will be analyzed using bivariate correlations. Increased levels of anxiety and decreased heart rate variability are anticipated outcomes of this study. Findings will assist in identifying health risks in this vulnerable population.

Missions involve locating natural resources such as oil deposits, determining if the area is a feasible location for deployment of sea and air systems for many operations, and to obtain water and mineral samples to study and monitor the changing Arctic environment. Thus far, we demonstrated the feasibility of an autonomous walking robot that can be used to explore the Arctic by walking under a sheet of ice. A key component of this is that by controlling the robot’s buoyancy the robot will be capable of walking upside down under a wooden plank. We water proofed a commercially available model robot and carried out the experiment in the Hydrodynamics Laboratory. The preliminary investigation contributes to an internal proposal submitted to I-Sense Internal Fund Program.

Show moreIn today’s society, different age groups seem to think and behave differently. Generational differences have influenced many controversial opinions discussed today. Not much research has been conducted on these differences, but in the studies which have been conducted, it has been concluded that there are substantial differences that exist between generations. In the limited amount of research that has been conducted, the sample was relatively small, making the survey incomprehensive. In order to understand these differences and where the opinions of generations differ, we developed an online survey about people’s opinions on controversial issues debated about in modern society. We found that there are statistically significant differences between age groups and their views on social issues such as religion, sex before marriage, same sex marriage, and abortion. Our results have shown that people are beginning to move away from the more traditional values and into more liberal viewpoints.

Show moreGopherus polyphemus is a threatened reptile native to the southeastern USA. Previous research suggests the South Florida (SF) climate may allow tortoises to reproduce year-round. Our goal was to evaluate the social interactions and home range of the Florida Atlantic University Preserve (FAUP) tortoise population, with an emphasis on reproductive behavior since minimal information is available. In this study, 12 FAUP tortoises had radio-transmitters attached and game cameras placed at their burrows. We hypothesized, 1) Gopher tortoise home ranges would differ between males and females, and between vegetation types and 2) Intraspecific gopher tortoise interaction frequencies would differ between vegetation types. Movement data has been mapped for 10 tortoises to reveal home ranges differ between sex and vegetation type. Camera data illustrates mounting as the most frequent interaction in the scrub vegetation. This research can be used to improve conservation efforts for the FAUP population.

The water is wetted on a simply supported rectangular piece of plate glass. Several glass inclinations are tested, with different exciting frequencies. Furthermore, we add different chemicals on the glass surface. This changes the contact angle of the water droplets. Doing this allows the examination of the effect of adhesion versus cohesion, in regards to the behavior of the water spreading on the plate glass. Our attempt to elucidate the relevant physics is driven by the goal of providing a basis for replacing windshield wipers of future automobiles.

Show moreIn China, one surprising factor in mitigating the growth of fossil fuel consumption has been the widely criticized One Child Policy. Without this unpopular policy, the demand for foreign oil would actually be dramatically higher. According to the Chinese defense scientist Song Jian, before the one child policy was implemented, the average fertility in China was 3 children per woman and that the population would reach 4 billion by 2080. By forcefully restricting fertility to 1 child per woman, the government managed to slow the nation’s population growth. With 1.4 billion people today, China still has attained the status of the largest oil importer in the world, and this correlates with their surpassing the US in automobile sales. Nations often face difficult challenges in deciding how to balance development goals with other factors. This poster will demonstrate the importance of an expanded scope of factors in weighing these decisions.

Climate change is a prominent issue today, with people having conflicting viewpoints about it. Government intervention on the subject of climate change is widely debated. To understand the differing perspectives on climate change, we developed an online survey consisting of 12 questions. We gathered 500 responses from people all over the United States. Overall, our findings showed that people believe in climate change. However, there is a statistically significant difference on the views of climate change based on people’s party affiliation. Republicans were the highest group of all the political parties surveyed to say that the government should not have a concern for climate change. This survey depicts the conventional view that Republicans hold on the issue of climate change.

The ability of vignettes, a brief narrative without a conclusion, to transport readers is unknown. The purpose of this study is to determine if vignettes can be used to transport readers into a narrative and also to explore the link between transportation and negative affect. Each participant was presented 11 bullying vignettes sequentially and were asked to respond to the Transportation Scale and the Negative Affect Scale. Descriptive and inferential analysis were performed. The results showed that readers were transported into the bullying vignettes and that there is a slight positive correlation between transportation and negative emotions (r=.339).

Food is now evolving, preferences are varying from natural tastes to unnatural alterations due to chemical additives. We felt more research is needed to understand what motivates consumers to purchase varying types of foods. To understand consumers’ views on food preferences, we developed an online survey with fifteen questions and collected responses from 498 people. Our findings show a statistically significant difference between people of different gender, age, and regions regarding motivations to purchase food and food labeling. With this knowledge, we may better understand what people of different demographics feel regarding the current state of food wellness, and why they might prefer certain actions over others due to their diverse backgrounds.

However, there is no standardized method to isolate exosomes. We hypothesize that polymer-based kits, in particular ExoQuick-TC (EQTC), may be better for isolating exosomes when compared to ultracentrifugation. In this study, we used three different methods to isolate exosomes from 4T1 murine mammary tumor cells. Samples isolated through ultracentrifugation (UC), EQTC, and Total Exosome Isolation Reagent (TEIR) were analyzed to assess quantity and quality of exosomes by nanoparticle tracking analysis (NTA) and flow cytometry (FC). Using NTA, we found that each method yielded samples with varying average concentration and particle size. FC analysis revealed UC to be the most effective method in yielding a high number of verified exosomes. Standardizing the isolation method and assessment will help in determining the role of exosomes in cancer metastasis.

This project explores the structure of trabecular (spongy) bone, which changes with force direction and magnitude, from the vertebral column of manatees. The goal of this research is to investigate the structural properties of manatee vertebral trabecular bone to better understand this animal's development and swimming mechanics. Vertebrae were dissected from four regions of the vertebral column and scanned with micro-computed tomography. Images were analyzed in BoneJ to quantify trabecular width, number, length, bone volume fraction (amount of bone/total area) and degree of anisotropy (orientation bias). Results from this project will be paired with mechanical data in future work to better understand forces on the vertebral column in a swimming mammal throughout development, and how these properties may have diverged from those found in their terrestrial counterparts.

This questions the underlying uncertainty of the future of contact sports. Our project addresses the question of hypothetically, if you had children, knowing what we know today about concussions/head related injuries, would you allow them to play contact sports. The decision to allow your child to play contact sports was motivated by the gender and age gap. The different levels of education had a statistically significant impact on the knowledge surrounding the current professional football and hockey concussion protocols.

Currently, society's stereotypes and attitudes about rape negatively influence rape culture by promoting rape myths that put blame on the victim or excuse perpetrators for their actions. The media also plays a significant role by promoting the romanticization of rape in pornography or the implicitly encouraging the action of rape in mainstream songs, books, etc. However, society has also influenced rape culture positively by creating social movements that raise awareness about rape and the solutions to combat it.

In order to see the views of Americans regarding the challenges of software technologies, we conducted an online survey, gathering 500 responses. In recent news stories, it has been shown that there is a gender gap in the tech industry, but the women that participated in our survey are interested in learning software engineering as much as men. Additionally, our research found that younger people are not only required to use software tools more frequently but are the most interested in learning how to build them. Finally, we found that a majority of people do not have any experience developing software. Our survey highlights some of the challenges of software technologies in the economy.

These methods rely on researchers to pick the animals swimming speed. We have been focusing on volitional kinematics in the lab where we quantify swimming as determined by the fish. However, our volitional swimming experiments are still limited to the space available in a lab setting. In this study, we examine swimming kinematics of black tip sharks (Carcharhinus limbatus) during their annual winter aggregations in South Florida. Using an aerial drone, video of sharks can be obtained through noninvasive methods in the wild, and examined frame-by-frame using the Loggerpro software. We track points along the shark’s midline to examine body curvature, tailbeat frequency, tailbeat amplitude, and whole-body swimming velocity. These data represent the first time we have been able to quantify kinematics in a free-swimming shark in the wild.

SCUBA is used to collect octopus prey remains and gather supplemental feeding images to determine diets of each species. A 24h octopus monitoring camera records foraging activity times for each species. The common octopus consumes bivalves (49%), gastropods (32%) and crustaceans (19%), and forages at dawn, dusk, and nocturnal hours. The Atlantic longarm octopus consumes crustaceans (89%) and bivalves (11%), and forages during diurnal hours. Results suggest there is diet overlap between species and octopuses use temporal partitioning. This study provides additional findings to cephalopod niche partitioning literature, novel information on the ecology of the Atlantic longarm octopus, and conservation requirements for sand-dwelling species.
