Description
Ketone bodies are produced in the liver from the acetyl CoA derived from fatty acids that cannot enter the Krebs cycle. This is a sub-analysis of a larger study which had numerous outcome markers. This analysis focuses on the relationship between ketone blood levels and cognition. The study looked at the relationship between Time Restricted Feeding (TRF), a method of intermittent fasting. TRF is something that can be easily adapted into an individual’s lifestyle and has been shown to have multiple advantages. This 8-week study began with 23 enrolled participants, but due to COVID-19 only 11 participants could be tested for cognition and blood ketone levels after week 4. All participants had similar ranges of weight, height, age, BMI, hip, and waist measurements at baseline. Moreover, these demographic variables were not related to ketone levels or cognition. The data indicate that ketone bodies increased in participants practicing TRF and that the increase in ketone bodies in the blood, specifically β-hydroxybutyrate was strongly correlated to increased cognitive function. This is consistent with theories that elevated ketone levels allowed for early hunter-gather communities and other mammals to survive prolonged periods of nutrient deprivation while keeping high cognitive function.

Description
Trichoplax adhaerens (Placozoa) is the simplest multicellular animal to be described. This organism lacks nervous tissue, muscle tissue and organs, and is composed of only five cell types organized into three layers. Placozoa are gaining popularity as a model organism due to their simple make-up and completely sequenced genome. The complete sequencing of this organism’s genome has revealed the presence of important genes in cancer such as TP53 and MDM2 genes. Along with the presence of these genes, there are also additional pathways commonly deregulated in cancer that are well conserved in this organism. T. adhaerens are able to survive exposure to 160Gy and even 240Gy of X-ray radiation. Though small dark bodies form within the main body, they tend to extrude those masses, and continue to reproduce afterwards. After exposure to both grades of radiation, there was a greater increase in the apparent population size of the treated population than the control population. There was also a greater decrease in surface area of the organisms exposed to 160Gy than the control organisms. This increase in population and decrease in surface area of the treated organisms could be due to the extruded bodies. We hypothesize that the observed extrusion is a novel cancer defense mechanism for ridding the animal of damaged or mutated cells. This hypothesis should be tested through longitudinal observation and genetic analysis of the extruded bodies.

Curricular Design in Languages for Specific Purposes: The Case of a Needs Analysis for the Design of a Spanish for Pharmacists Course is a thesis project that argues for the creation of a Spanish course for pharmacists based in the model of Languages for Specific Purposes courses. In order to do this, a needs analysis was conducted by surveying and interviewing a pharmacist and medical Spanish instructor. Based on these results, objectives, activities, and evaluation criteria were created for such a course. The needs analysis found that Spanish use in a pharmacy is not limited to one ability or task, but rather an integration of many such as reading, writing, listening, and speaking. This course would be an invaluable addition to pharmacy schools in the United States due to the growing Hispanic population across the country.

Description
It happened in 1824. Again, it happened in 1876. And 1888. And then again in 2000. Most recently, in 2016. Five times the president has been elected through the Electoral College without attaining the popular vote. Is this a feature, bug, or necessary evil of the electoral system? While the support for the national popular vote movement has grown significantly in the past decade, there are many fervent opponents. Many of the adversaries to a popular vote system argue that under a national popular vote system, candidates would visit only the most densely populated areas in the country and then simply work to get all votes possible, gaining enough support to win the election without gaining much support from the rest of the country. To analyze these key arguments, this paper tests two hypotheses, the first of which is that under a popular vote system, densely populated areas are given more attention from presidential candidates than would be proportionately expected based on population. The second hypothesis is that candidates will spend more money on advertising per person in larger cities than in smaller cities. This paper will outline research from both a social media analysis and from a statistical analysis of specific state Senate elections and their media markets before concluding by refuting the two hypotheses and suggesting that a national popular vote system would not cause vast populations of Americans to be ignored any more than they currently are.

Description
Strong Mothers Strong Teeth is an initiative to educate mothers and pregnant women about the importance of maintaining their own and their child(ren)’s oral health. This project presents evidence that shows a lack of oral health education among mothers about how to care for their oral health while pregnant and their child’s oral health post birth. The recognition and identification of these disparities led to the content deemed necessary to be included in the education of mothers and pregnant women. By collecting and analyzing pamphlets and information gathered from health clinics and homeless shelters in Arizona and California, we created our own pamphlets based on analysis of the effectiveness of the information using content analysis and Flesch-Kincaid readability scores. This led to the creation of two pamphlets to educate mothers on oral health care, the first focused on preventing tooth decay in women during their pregnancy and for their baby, post-birth, and the second provided a timeline guide on oral health for the mother and child.

Description
As Alzheimer’s disease (AD) increases in incidence, there is an increased investigation into the pathogenesis of the disease in hopes of finding a cure to the neurodegenerative disease. The two key hallmarks of AD consist of amyloid beta plaques and hyperphosphorylated tau fibrillary tangles. Amyloid beta is a peptide that is proteolytically cleaved from the type I transmembrane glycolytic amyloid precursor protein (APP). APP is highly conserved across species, suggesting the importance of APP in healthy brain functioning. However, when APP is cleaved through the amyloidogenic pathway it produces amyloid beta. The trafficking of APP within neurons has been a new endeavor for neurodegenerative disease research, as reduced retrograde trafficking of APP has been hypothesized to increase the likelihood of the amyloidogenic cleavage of APP, resulting in increased amyloid beta presence (Ye et al., 2017). The findings of this study suggest that transport of APP within neurons is significantly inhibited by increased extracellular glutamate concentration. The addition of human primary astrocytes within a human neuron co-culture allowed for significantly increased retrograde transport of APP within neurons, even within high glutamate conditions. These finding enhance the current field of research regarding astrocytes neuroprotective role within the brain, but bring attention to the role that astrocytes have upon regulation of the axonal transport of proteins within neurons.

Description
This paper explores the news and entertainment media spheres before and after September 11, 2001 with regards to Islamophobia and how America views Muslims. Specific data figures and examples were used to highlight how news media has changed following the attack on the Twin Towers, while movies, television shows, and video games were used for the entertainment sphere. Specific examples of dehumanization of Arab characters were used to underscore exactly how American entertainment media refuse to use Middle Eastern characters in positive roles. The research showed that the favorable views in news media increased following 9/11, however the frequency of news stories also increased significantly. Entertainment media also has made leaps and bounds with regards to positive Arab influence, however much work is yet to be done in the entertainment industry.

Description
In eukaryotes, most messenger RNA precursors (pre-mRNA) undergo extensive processing, leading to the cleavage of the transcript followed by the addition of a poly(A) tail. This process is executed by a large complex known as the Cleavage and Polyadenylation Complex (CPC). Its central subcomplex, the Cleavage and Polyadenylation Specificity Factor (CPSF) complex is responsible for recognizing a short hexameric element AAUAAA located at the 3’end in the nascent mRNA molecule and catalyzing the pre-mRNA cleavage. In the round nematode C. elegans, the cleavage reaction is executed by a subunit of this complex named CPSF3, a highly conserved RNA endonuclease. While the crystal structure of its human ortholog CPSF73 has been recently identified, we still do not understand the molecular mechanisms and sequence specificity used by this protein to induce cleavage, which in turn would help to understand how this process is executed in detail. Additionally, we do not understand in additional factors are needed for this process. In order to address these issues, we performed a comparative analysis of the CPSF3 protein in higher eukaryotes to identify conserved functional domains. The overall percent identities for members of the CPSF complex range from 33.68% to 56.49%, suggesting that the human and C. elegans orthologs retain a high level of conservation. CPSF73 is the protein with the overall highest percent identity of the CPSF complex, with its active site-containing domain possessing 74.60% identity with CPSF3. Additionally, we gathered and expressed using a bacterial expression system CPSF3 and a mutant, which is unable to perform the cleavage reaction, and developed an in vitro cleavage assay to test whether CPSF3 activity is necessary and sufficient to induce nascent mRNA cleavage. This project establishes tools to better understand how CPSF3 functions within the CPC and sheds light on the biology surrounding the transcription process as a whole.

Description
Transient receptor potential (TRP) channels are a superfamily of ion channels found in plasma membranes of both single-celled and multicellular organisms. TRP channels all share the common aspect of having six transmembrane helices and a TRP domain. These structures tetramerize to form a receptor-activated non-selective ion channel. The specific protein being investigated in this thesis is the human transient receptor potential melastatin 8 (hTRPM8), a channel activated by the chemical ligand menthol and temperatures below 25 °C. TRPM8 is responsible for cold sensing and is related to pain relief associated with cooling compounds. TRPM8 has also been found to play a role in the regulation of various types of tumors. The structure of TRPM8 has been obtained through cryo-electron microscopy, but the functional contribution of individual portions of the protein to the overall protein function is unknown.
To gain more information about the function of the transmembrane region of hTRPM8, it was expressed in Escherichia coli (E. coli) and purified in detergent membrane mimics for experimentation. The construct contains the S4-S5 linker, pore domain (S5 and S6 transmembrane helices), pore helix, and TRP box. hTRPM8-PD+ was purified in the detergents n-Dodecyl-B-D-Maltoside (DDM), 16:0 Lyso PG, 1-Palmitoyl-2-hydroxy-sn-glycero-3-phosphoglycerol (LPPG), and 14:0 Lyso PG, 1-Myristoyl-2-hydroxy-sn-glycero-3-phosphoglycerol (LMPG) to determine which detergent resulted in a hTRPM8-PD+ sample of the most stability, purity, and highest concentrations. Following bacterial expression and protein purification, hTRPM8-PD+ was studied and characterized with circular dichroism (CD) spectroscopy to learn more about the secondary structures and thermodynamic properties of the construct. Further studies can be done with more circular dichroism (CD) spectroscopy, planar lipid bilayer (BLM) electrophysiology, and nuclear magnetic resonance spectroscopy (NMR) to gain more understanding of how the pore domain plus contributes to the activity of the whole protein construct.

Description
The integration of behavioral health services into primary care in a rapidly evolving innovation that has shown potential to improve access to care, health outcomes, and lower health costs. In an effort to reform healthcare system, integrating behavioral health services become a vital part of the patient-centered medical home (PCMH). As research and developments in integration continue to evolve, there is a need to identify consistencies, discrepancies, and gaps in the field to inform the best ways to move forward. This study is a systematic review seeking to identify trends, gaps, and future directions of research in integrated behavioral health in primary care. Using Google Scholar 171 papers were included, 95 being original research and 76 being reviews, commentary, and editorials. From the results, it is clear that the case for integration has been made, and now it is time to move to the specifics. Both empirical and theoretical evidence supports the benefits of integration to patients and health systems. However, there is a lack of literature that tackles problems that hinder or facilitate integration in independent clinics with unique characteristics. Most notably, specific interventions that are effective and appropriate in primary care, payment reforms that are feasible and sustainable, and the effect of integration on health disparities.
