Description
Students not only deserve to be actively involved and engaged in learning content knowledge, but it can in fact help them learn better. Arguably too few classrooms actually utilize teaching methods that support this kind of environment. There is perhaps fear that methods like integrated curriculum may detract from student knowledge. The purpose of this intervention study was to determine how the integration of dance and social studies with an anthropological framework effects student learning of content knowledge in social studies, as well as student attitude toward the topic. Research questions that were addressed in this study are the following: (a) How does the integration of dance and social studies with an anthropological framework affect students' chapter test scores when compared to typical instruction?; (b) How does the integration of dance and social studies with an anthropological framework affect students' attitude toward social studies when compared to typical instruction?. Participants were two 6th grade classes at the same elementary school. As a supplement to a unit on Ancient Egypt, the experimental group received four intervention lessons, taught by the investigator, incorporating creative dance to encourage student exploration and increased understanding of content. An anthropological framework was also implemented to foster respectful investigation of culture. Results show that at posttest the intervention group had significantly higher content knowledge, as measured by a chapter test, compared to the control group. This suggests that this program did in fact help students to reach a better understanding of content. Though surveys showed no difference in attitude between groups or over the course of the study, qualitative student responses from the experimental group suggest extremely positive feelings towards concepts covered in the intervention lessons.

How are perceptions of morality and disgust regarding meat consumption related to each other? Which factor is more salient in determining one's willingness to eat the meat of a specific animal? How do these answers vary across religious groups? This study investigates the ways that concepts like morality and disgust are related to food preferences and hopes to shed light on the mechanisms that enforce culturally sanctioned food taboos. The study compares 4 groups of people in the U.S.: Christians (n = 39), Hindus (n = 29), Jews (n = 23), and non-religious people (n = 63). A total of 154 participants were given surveys in which they rated their feelings about eating various animals. Data from Christian and non-religious groups exhibited similar patterns such as a high likelihood of eating a given animal when starving, while results from Jews and Hindus were consistent with their religion's respective food taboos. Despite these differences, morality and disgust are strongly correlated with one another in almost all instances. Moreover, morality and disgust are almost equally important considerations when determining willingness to eat when starving.

Description
This thesis examines the grinding stone fragments found at the archaeological sites of Calixtlahuaca, Yautepec, Cuexcomate and Capilco; the first in the Toluca Valley, and the latter three from the state of Morelos, all in Mexico. General patterns in grinding stone distribution within and between the sites are explored and an analysis comparing the porosity of stones to imported ceramics (as a wealth index) is attempted. Within the grinding stone assemblage, there is some suggestion that the Aztec conquest may have impacted artifact morphology and distribution, likely as a result of increasing resource obligations due to tribute or growing populations.

Description
Paleodietary analysis through the interpretation of stable isotopic analyses can be used to determine the approximate diet consumed at archaeological sites. The following question was investigated through the course of this research: What are the differences between the Middle Horizon capital of Tiwanaku and the associated colony of Chen Chen; and what do these differences, including those associated with paleodiet, suggest about interactions between the two sites? The main hypothesis suggested a similar dietary analysis between the two sites with two possible explanations. First, it is possible that similarities between the sites were due to the exchange and consumption of goods at both locations, perhaps through trade. Secondly, it is possible that the similarities were due to the acquisition of similar goods through local sourcing or limited trade. To assess this, an analysis was conducted based on δ13Cdiet (VPDB) values in the comparison of the city center Tiwanaku and the agricultural site of Chen Chen. Archaeological bone samples were processed from a diverse group of individuals at Chen Chen and combined with published values by Tomczak (2001), then compared against δ13C from Tiwanaku, published by Berryman (2010). After conversion to δ13Cdiet (VPDB) as described by Kellner and Schoeninger (2007), it was determined that there was no statistically significant difference between the δ13Cdiet (VPDB) values from either site, suggesting a similar ratio of goods consumed. These values were then compared to baseline values from the region to determine an approximate ratio of C3 to C4 flora or dependent fauna consumed. These data most likely support the second explanation of the main hypothesis, that both sites had access to similar goods through local sourcing or limited trade as an explanation for their similarity. However, because a similar ratio of foods consumed was determined in this analysis, it is still possible that trade occurred in both directions between Tiwanaku and Chen Chen. Additional isotopic analyses would be required to support the first claim, which can be addressed in future research projects.

Description
Adaptive therapy utilizes competitive interactions between resistant and sensitive cells by keeping some sensitive cells to control tumor burden with the aim of increasing overall survival and time to progression. The use of adaptive therapy to treat breast cancer, ovarian cancer, and pancreatic cancer in preclinical models has shown significant results in controlling tumor growth. The purpose of this thesis is to draft a protocol to study adaptive therapy in a preclinical model of breast cancer on MCF7, estrogen receptor-positive, cells that have evolved resistance to fulvestrant and palbociclib (MCF7 R). In this study, we used two protocols: drug dose adjustment and intermittent therapy. The MCF7 R cell lines were injected into the mammary fat pads of 11-month-old NOD/SCID gamma (NSG) mice (18 mice) which were then treated with gemcitabine.<br/>The results of this experiment did not provide complete information because of the short-term treatments. In addition, we saw an increase in the tumor size of a few of the treated mice, which could be due to the metabolism of the drug at that age, or because of the difference in injection times. Therefore, these adaptive therapy protocols on hormone-refractory breast cancer cell lines will be repeated on young, 6-week old mice by injecting the cell lines at the same time for all mice, which helps the results to be more consistent and accurate.

Description
This project examines the literary figures of Tristan and Isolde, looking to see how each character is portrayed, how their portrayals change through time, and takes a socio-cultural perspective in attempts to explain why these portrayals were used, and why they changed. Three different versions of the Tristan and Isolde story from three different time periods were used: Le Morte Darthur by Sir Thomas Malory from the 1400's, Idylls of The King by Lord Alfred Tennyson from the 1800's, and the film Tristan + Isolde distributed by 20th Century Fox in the mid 2000's. For each version of the story, the primary text or film, along with secondary sources, were used to determine how each character was portrayed. This was done by examining Tristan and Isolde's physical appearances, stations in life, actions, and personality/tone. These portrayals from each version were then compared with portrayals from the other versions to determine what changes had occurred. Finally, secondary textual information was used to examine the culture in which each version was originally published, specifically examining such socio-cultural changes that could explain why the previously determined portrayals of Tristan and Isolde were used and why they differ from versions of these characters from different time periods. The results of this study found that some characteristics of Tristan and Isolde's portrayals do not change through time. Specifically, their physical appearances and stations in life are, for the most part, fixed. Tristan is always a handsome, strong, and noble knight/warrior while Isolde is always a beautiful and delicate princess. Other characteristics, such as personality/tone and actions do change drastically from one version to the next in accordance with the changing culture in which the authors and audience members lived.

Description
Glioblastoma multiforme (GBM) is an aggressive malignant brain tumor with a median prognosis of 14 months. Human hairless protein (HR) is a 130 kDa nuclear transcription factor that plays a critical role in skin and hair function but was found to be highly expressed in neural tissue as well. The expression of HR in GBM tumor cells is significantly decreased compared to the normal brain tissue and low levels of HR expression is associated with shortened patient survival. We have recently reported that HR is a DNA binding phosphoprotein, which binds to p53 protein and p53 responsive element (p53RE) in vitro and in intact cells. We hypothesized that HR can regulate p53 downstream target genes, and consequently affects cellular function and activity. To test the hypothesis, we overexpressed HR in normal human embryonic kidney HEK293 and GBM U87MG cell lines and characterized these cells by analyzing p53 target gene expression, viability, cell-cycle arrest, and apoptosis. The results revealed that the overexpressed HR not only regulates p53-mediated target gene expression, but also significantly inhibit cell viability, induced early apoptosis, and G2/M cell cycle arrest in U87MG cells, compared to mock groups. Translating the knowledge gained from this research on the connections between HR and GBM could aid in identifying novel therapies to circumvent GBM progression or improve clinical outcome.

Description
Due to the nature of animals, even domesticated pets, animal scavenging of human remains is an important taphonomic factor. This area of study has, however, been undercounted in the current literature. The purpose of this study was to begin the first step in creating a taphonomic profile for urban / household animal scavenging as distinguishable from manmade tool marks. Using volunteered animals and regularly available tools, alterations were made on beef ribs in order to characterize the distinguishing profiles between the two groups. It was found that animal scavenging alterations, in the short term (20 minutes used in this study) have a distinctly different appearance than tool mark alterations. Animal scavenging has less visible alterations, consistent bite morphology across different species, and symmetrical cut marks along the midsection of the long bones. Ultimately, this study was a successful first step in furthering taphonomic alteration database research across various biomes and conditions.

Description
Since Metastatic Osteosarcoma is unresponsive to most of the current standards of care currently available, and yields a survival rate of 20%, it is pertinent that novel approaches to treating it be undertaken in scientific research. Past studies in our lab have used a The Immune Blockade Therapy, utilizing α-CTLA-4 and α-PD-L1 to treat mice with metastatic osteosarcoma; this resulted in 60% of mice achieving disease-free survival and protective immunity against metastatic osteosarcoma. 12 We originally wanted to see if the survival rate could be boosted by pairing the immune blockade therapy with another current, standard of care, radiation. We had found that there were certain, key features to experimental design that had to be maintained and explored further in order to raise survival rates, ultimately with the goal of reestablishing the 60% survival rate seen in mice treated with the immune blockade therapy. Our results show that mice with mature immune systems, which develop by 6-8 weeks, should be used in experiments testing an immune blockade, or other forms of immunotherapy, as they are capable of properly responding to treatment. Treatment as early as one day after should be maintained in future experiments looking at the immune blockade therapy for the treatment of metastatic osteosarcoma in mice. The immune blockade therapy, using α-PD-L1 and α-CTLA-4, seems to work synergistically with radiation, a current standard of care. The combination of these therapies could potentially boost the 60% survival rate, as previously seen in mice treated with α-PD-L1 and α-CTLA-4, to a higher percent by means of reducing tumor burden and prolonging length of life in metastatic osteosarcoma.

Description
PD-L1 blockade has shown recent success in cancer therapy and cancer vaccine regimens. One approach for anti-PD-L1 antibodies has been their application as adjuvants for cancer vaccines. Given the disadvantages of such antibodies, including long half-life and adverse events related to their use, a novel strategy using synbodies in place of antibodies can be tested. Synbodies offer a variety of advantages, including shorter half-life, smaller size, and cheaper cost. Peptides that could bind PD-L1 were identified via peptide arrays and used to construct synbodies. These synbodies were tested with inhibition ELISA assays, SPR, and pull down assays. Additional flow cytometry analysis was done to determine the binding specificity of the synbodies to PD-L1 and the ability of those synbodies to inhibit the PD-L1/PD-1 interaction. Although analysis of permeabilized cells expressing PD-L1 indicated that the synbodies could successfully bind PD-L1, those results were not replicated in non-permeabilized cells. Further assays suggested that the binding of the synbodies was non-specific. Other tests were done to see if the synbodies could inhibit the PD-1/PD-L1 interaction. This assay did not yield any conclusive results and further experimentation is needed to determine the efficacy of the synbodies in inhibiting this interaction.
