Managing plastic waste is a challenge for a small island nation like American Samoa. As a result, they need access to alternative products that will benefit their environment. The alternative products must also be equally cost-effective for local restaurants in order for them to be a viable option. The study concluded that Polylactic Acid (PLA) was the best material for take-out containers, paper was the best for cups, and wood was the best for utensils. Future research should focus on any other alternatives that become available for shipment to American Samoa, effects caused by an increase in cornstarch-based products (i.e., PLA take-out containers), and the satisfaction of both the restaurants and their customers based on the recommendations provided in this study.

In this study, models will be introduced which are developed from historical UFC data and aim to predict the fight outcomes between mixed martial arts fighters within the UFC. The paper will explore multivariate linear probability regression analysis using variables which were provided and developed from a large dataset to effectively predict the probability of a fighter winning a given fight. It will analyze several multivariate regression models and compare, internally, the accuracy of each model and account for limitations within the models. Then, the model’s efficacy will be tested by recent UFC fights and adjusted to find a more accurate equation that maximizes profit in sports betting using implied probability from betting odds and comparing them to the model’s predicted probabilities.

The reproductive biology of Aspidoscelis, particularly the known parthenogenetic species, has fascinated herpetologists for decades. In order to understand parthenogenesis within Aspidoscelis, which has evolved multiple times following hybridization events between distinct sexual species within the genus, it is imperative to comprehend underlying reproductive mechanisms and strategies inherent in the sexual ancestors. Through comprehensive genomic analyses, including RADseq data and synteny mapping, this study investigates sex determination mechanisms and identifies punitive sex-linked loci in two sexual Aspidoscelis species. The analysis reveals markers potentially associated with sex differentiation, offering insights into the chromosomal evolution and genetic basis of reproduction in these lizards. Despite challenges in identifying sex-linked loci using existing methods, the FST-based approach adopted here proved promising, with its ability to highlight genomic regions potentially involved in sex determination. Our findings suggest that chromosome 13 in A. gularis is homologous to the previously identified sex chromosome 3 in A. tigris. This study contributes to understanding the intricate genetic processes underlying parthenogenesis and karyotypic evolution in Aspidoscelis, paving the way for future studies elucidating the complexities of reproduction in vertebrates.

The use of genetic management in conservation has sparked much debate around the ethical and environmental impacts of the plans. A case study on the conservation of leopard frogs in Arizona was analyzed to better understand the benefits and issues surrounding genetic management plans. The first part of the case focuses on the recent management plan for Chiricahua Leopard Frogs implemented by the Arizona Game and Fish Department. The goal of the plan is to better understand the genetic dynamics of the established Chiricahua Leopard Frog populations to develop a more effective management plan. The second part of the case focuses on the Arizona Game and Fish Department’s management of the Northern Leopard Frog. There was little success with the initial breed and release program of the native species, however a nonnative subspecies of Northern Leopard Frog was able to establish a thriving population. This case study exemplifies the many complications with genetic management plans and the importance of careful assessment of options when deciding on a genetic management plan. Despite the complexity of genetic management plans, it is an important method to consider when discussing the conservation of a species.

Not only is Tyrosine one of the 20 amino acids that make proteins, but its catabolism also has many branches including a pathway that can be found in humans. Any mutations in the enzymes of this pathway can cause many disorders in humans including hereditary tyrosinemia type I. For this reason, understanding how tyrosine gets degraded in humans can help in developing therapies against disorders of the human tyrosine catabolism pathway. In this work, we explored what type of enzymes do microbes that reside within humans (the human microbiome) have to degrade tyrosine and how we can take advantage of the enzymes of the human microbiome for the betterment of human health and physiology.

The purpose of this study was to determine the feasibility of a mindfulness-based intervention among pregnant women (12-20 weeks’ gestation) using a mobile meditation app, Calm. This study involved 100 participants who were recruited nationally due to the COVID-19 pandemic. This study was reviewed and approved by the Institutional Review Board of Arizona State University (STUDY STUDY00010467). All participants were provided an informed consent document and provided electronic consent prior to enrollment and participation in this study. This study was a randomized, controlled trial (trial registration: ClinicalTrials.gov NCT04264910). Participants randomized to the intervention group were asked to participate in a minimum of 10 minutes of daily meditation using a mindfulness meditation mobile app (i.e., Calm) for the duration of their pregnancy. Participants randomized to the standard of care control group were given access to the app after they gave birth. Both the intervention and control groups were administered surveys that measured feasibility outcomes, perceived stress, mindfulness, self-compassion, impact from COVID-19, pregnancy-related anxiety, depression, emotional regulation, sleep, and childbirth experience at four time points: baseline (12-20 weeks gestation), midline (24 weeks gestation), postintervention (36 weeks gestation), and follow-up survey (3-5 weeks postpartum). Data is currently being analyzed for publication.

Triple Negative Breast Cancer (TNBC), indicated by the absence of estrogen, progesterone and human epidermal growth factor receptor 2 (HER2), is the most aggressive form of breast cancer characterized by high rates of metastasis and low survival. Among those diagnosed with TNBC, 34% contain Inhibitor of Growth 4 (ING4) deletion that is associated with poor patient outcomes. We previously showed that ING4 negatively regulates NF-B in breast cancer. Previous studies show parthenolide, a compound found in feverfew (Tanacetum parthenium) to inhibit NF-B in cervical and gastric cancer. We hypothesized that parthenolide inhibits cytokine-induced activation of NF-B in ING4 deficient TNBC cells. To test the hypothesis, previously established vectors, v2, ING4 wildtype and v2h1, ING4-deleted were synthesized in MDA-MB 231, a TNBC cell line, using a CRISPR/Cas9 system. Inflammatory cytokines, IL-1 and TNF, were tested in ING4 wildtype or ING4 deleted cells for elicited phosphorylation of NF-B, proliferation, and migration in the presence or absence of parthenolide. The results showed that TNF or IL-1 induced translocation phosphorylation of NF-B regardless of ING4 deletion. ING4 inhibited proinflammatory cytokine induced pp65, consistent with previous studies demonstrating the negative regulation of NF-B in ING4-sufficent cell lines. We found the optimal working dose of parthenolide, 100nM, had no effect on cell proliferation in the presence or absence of IL-1. Parthenolide inhibited IL-1induced phosphorylation of NF-B regardless of ING4 deletion. Parthenolide inhibited TNF-induced phosphorylation of NF-B in ING4-deleted cell lines. Moreover, parthenolide induced migration of TNBC cells regardless of ING4 presence of absence. TNF and parthenolide treated samples in ING4-deleted cell lines were found to inhibit cell migration to basal level. These results demonstrate the difference in inhibitory mechanism of parthenolide in induced phosphorylation of NF-B through proinflammatory cytokines TNF or IL-1This is demonstrated by the exclusivity of parthenolide inhibition of TNF induced phosphorylation of NF-B in ING4-deleted TNBC cell line. In contrast, parthenolide inhibition of IL-1 induced phosphorylation of NF-B occurred regardless of ING4 deletion. These results may inhibit parthenolide as an alternative to those with ING4-deleted TNBC due to its role in inducing cancer phenotype cell migration.

Lutein and zeaxanthin are two important carotenoid vitamins related to ocular health and human visual processing. These vitamins can be ingested through supplementation and in regular diet. They concentrate in the central retina where they form a filter of macular pigment and protect the eye from high energy blue and yellow light. We examined participants who had a natural diet of high vs low lutein and zeaxanthin intake on tests of contrast sensitivity and glare disability. We also examined participant performance while wearing blue light blocking glasses in order to determine whether these glasses serve a similar protective function as macular pigment in benefiting participants on contrast sensitivity and glare disability tasks. Most of our data did not show statistically significant differences between the high and low lutein and zeaxanthin groups. An unexpected result that the blue blocker glasses hindered the ability of low lutein participants on their glare disability test was observed. We hypothesize that this is due to light scatter produced by the by glasses resulting in an impoverish retinal image reaching the primary visual cortex. Further research is required to examine this new finding.

A long personal struggle with Lyme disease prompted me to review the current literature to better understand what remains elusive to researchers and physicians. Lyme disease was first discovered in Connecticut in the mid-1970’s, however, in Europe, it was already being treated with antibiotics. The disease is caused by a spirochete bacteria named Borrelia burgdorferi after the scientist who married the European syndromes associated with the microbe to the disease found in the United States. Borrelia burgdorferi is capable of evading the immune system through a variety of methods, some of which are still not clearly understood. Treatment for Lyme disease is effective and involves antibiotics over a variable duration depending on the presentation of the disease. Post-treatment Lyme Disease Syndrome (PTLDS) is the heart of the controversy surrounding this disease as patients continue to have debilitating symptoms with no clear cause.

As Big Data becomes more relevant, existing grouping and clustering algorithms will need to be evaluated for their effectiveness with large amounts of data. Previous work in Similarity Grouping proposes a possible alternative to existing data analytics tools, which acts as a hybrid between fast grouping and insightful clustering. We, the SimCloud Team, proposed Distributed Similarity Group-by (DSG), a distributed implementation of Similarity Group By. Experimental results show that DSG is effective at generating meaningful clusters and has a lower runtime than K-Means, a commonly used clustering algorithm. This document presents my personal contributions to this team effort. The contributions include the multi-dimensional synthetic data generator, execution of the Increasing Scale Factor experiment, and presentations at the NCURIE Symposium and the SISAP 2019 Conference.
