Mitochondrial methionyl-tRNA-formyltransferase (MTFMT) is essential for mitochondrial protein translation. The MTFMT gene encodes for an enzyme of the same name, which acts to formylate the methionine of mitochondrial Met-tRNA(Met). In Homo sapiens, MTFMT-formylated-tRNA is an initiator and elongator for the synthesis of 13 mitochondrially-encoded proteins in complexes I, III and IV of the ETC. To understand this mechanism, it is necessary to perform a comprehensive analysis of energy metabolism and oxidative phosphorylation (OXPHOS) among impacted patients. Alterations to this gene vary, with the most documented as a single-splice-site mutation (c.626C>T). Here, we discuss MTFMT involvement in mitochondrial protein translation and neurodegenerative disorders, such as Leigh Syndrome and combined OXPHOS deficiency, in two families. We aim to delineate the impact of OXPHOS dysfunction in patients presenting with MTFMT mutation.

Residential Choice’s Impact on Sustainable Transportation Options: A Study in the Phoenix Metro Area
Description
This study adds to the literature about residential choice and sustainable transportation. Through the interviews and the personal stories gathered, there was diversity shown in the residential location choice process. We also noticed that “commute” means different things to different households, and that many people did not consider their commute to work to be a primary factor determining their final home location. Moreover, many people were willing to increase their commute time, or trade access to desirable amenities for a longer commute. Commuting time to work was one example of the tradeoffs that homeowners make when choosing a home, but there were also others such as architectural type and access to neighborhood amenities. Lastly, time constraints proved to be a very significant factor in the home buying process. Several of our households had such strict time constraints that limited their search to a point of excluding whole areas. Overall, our study sheds light on transportation’s role in residential choice and underscores the complexity of the location choice process.

While non-invasive breast cancer treatments may be considered less costly in the short-term, over the course of a lifetime, a more aggressive treatment can be overall less costly, especially with recurrence cases; however, these more aggressive treatments are not necessarily covered by insurance and are difficult to discuss in the short amount of time in physician consultations. This analysis studied data from 982 women diagnosed with breast cancer over a five-year period to evaluate monetary costs associated with treatment options and incorporated five in-depth interviews to understand experiences and non-monetary costs. Data showed the most expensive option was a unilateral mastectomy with radiation therapy and the least costly option was breast conserving surgery. Interviews determined each woman evaluated the monetary costs with each treatment but most heavily focused on personal values, biases and recommended opinions when deciding on a treatment. The use of prompt sheets before physician appointments and consultations, along with the addition of financial counselor meeting with each patient can improve patient satisfaction and alleviate stress by simplifying a woman's choice in deciding a treatment. In addition, increased insurance coverage to include every treatment chosen by women (rather than on a case-by-case basis), specifically contralateral prophylactic mastectomy and additional screening options, could decrease long term costs \u2014 both monetarily and in quality of life for patients.

Background:
The positive impacts of yoga on stress, pain, and chronic disease has recently led to the integration of yoga as part of physical therapy (PT) treatment. Due to the lack of training for PTs related to yoga, there is currently a need to provide knowledge and education about how to safely and easily implement therapeutic yoga (TY) as a complementary treatment approach.
Objective:
The purpose of this study was to assess the readiness of PTs (those who do not currently prescribe TY to patients) to integrate TY into treatment, and secondly, the feasibility (i.e., acceptability, demand, and practicality) of a 5-week online TY training to improve the readiness of PT’s to utilize TY in their practice.
Methods:
Licensed Physical Therapist’s (n=103) were recruited nationally through social media and email. Eligible and consented participants were asked to register in a 5-week online TY training course, Readiness for Integrating Yoga Therapeutics into Rehabilitation for PTs (intervention). PTs perceptions of TY and the role of safety and confidence in prescribing TY to patients were measured at baseline and post-intervention using a customized survey. Feasibility outcomes were measured after completion of the 5-week online training course with a survey. Feasibility was measured with acceptability, demand, and practicality. Our benchmarks included: (1) at least 70% of PTs would find the course acceptable, (2) at least 60% would finish the course (i.e., demand) and (3) there would be significant improvements in PTs perceptions of TY.
Results:
A total of 95 licensed PTs registered in the 5-week online TY training course, with 60 PTs (63%) completing the intervention and surveys. Of the PTs who completed the 5-week online training course, most PTs felt they were not ready (n=19/60, 31.7%) or somewhat ready (n=25/60, 41.7%) to integrate TY prior to taking the online training. Over half of PTs thought the online training was acceptable (n= 50/60, 83.3%) and finished the course (n=60/95, 63%). There were significant improvements in personal readiness to prescribe TY, safety prescribing TY, confidence to prescribe TY, current understanding/knowledge of TY and feeling adequately trained and educated to use some form of TY techniques with patients.
Conclusion:
Findings suggest a 5-week online TY training course is feasible in improving PTs readiness to prescribe TY, safety prescribing TY, confidence to prescribe TY, current understanding/knowledge of TY and feeling adequately trained and educated to use some form of TY techniques with patients. Future studies are proposed to test the effectiveness of TY training and education opportunities with PTs to further advance the adoption of TY into PT practice.

Description
This research project investigated known and novel differential genetic variants and their associated molecular pathways involved in Type II diabetes mellitus for the purpose of improving diagnosis and treatment methods. The goal of this investigation was to 1) identify the genetic variants and SNPs in Type II diabetes to develop a gene regulatory pathway, and 2) utilize this pathway to determine suitable drug therapeutics for prevention and treatment. Using a Gene Set Enrichment Analysis (GSEA), a set of 1000 gene identifiers from a Mayo Clinic database was analyzed to determine the most significant genetic variants related to insulin signaling pathways involved in Type II Diabetes. The following genes were identified: NRAS, KRAS, PIK3CA, PDE3B, TSC1, AKT3, SOS1, NEU1, PRKAA2, AMPK, and ACC. In an extensive literature review and cross-analysis with Kegg and Reactome pathway databases, novel SNPs located on these gene variants were identified and used to determine suitable drug therapeutics for treatment. Overall, understanding how genetic mutations affect target gene function related to Type II Diabetes disease pathology is crucial to the development of effective diagnosis and treatment. This project provides new insight into the molecular basis of the Type II Diabetes, serving to help untangle the regulatory complexity of the disease and aid in the advancement of diagnosis and treatment.

With the ongoing student debt crisis and the continuing increase in the cost of attending a college or university, there has been an increasing conversation regarding the price of room and board. Prior studies have shown the presence of a relationship between the distance to a location of interest, but few have been done with college campuses in mind. To answer this question, we used the Hedonic Pricing Model in order to isolate the effect that the distance to campus has on the rental price of apartments. Our results showed a clear positive nonlinear relationship between distance to campus and the price of apartment rentals in the area surrounding Arizona State University.

Description
In 2016, in the United States alone, the cosmetics industry made an estimated 62.46 billion dollars in revenue (Revenue of the Cosmetic Industry in the U.S. 2002-2016 | Forecast). With a consistent increase in sales in the last several years, the industry has reached continued success even during times of hardship, such as the Great Recession of 2008. The use of Corporate Social Responsibility (CSR), external campaigns, and thoughtful packaging and ingredients resonates with targeted consumers. This has served as an effective strategy to maintain growth in the industry. Cosmetic companies promote their brand image using these sustainability tactics, but there seems to be a lack of transparency in this unregulated industry. The purpose of this thesis is to determine if the cosmetics industry is a good steward of the sustainability movement. Important terms and concepts relating to the industry will be discussed, then an analysis of sustainability focused cosmetic brands will be provided, which highlights the extent to which these brands engage in activities that promote sustainability. This is followed by an application of findings to a company that could benefit from using such practices. Overall, the analysis of the different brands proved to be shocking and disappointing. This is due to the sheer amount that scored very poorly based on the sustainability criteria developed. The cosmetics industry is too inconsistent and too unregulated to truly act as a good steward for sustainability. Though some companies in the industry succeed, these accomplishments are not consistent across all cosmetic companies. Hence, the cosmetics industry as a good steward for sustainability can only be as strong as its weakest link.

Description
The use of generalized linear models in loss reserving is not new; many statistical models have been developed to fit the loss data gathered by various insurance companies. The most popular models belong to what Glen Barnett and Ben Zehnwirth in "Best Estimates for Reserves" call the "extended link ratio family (ELRF)," as they are developed from the chain ladder algorithm used by actuaries to estimate unpaid claims. Although these models are intuitive and easy to implement, they are nevertheless flawed because many of the assumptions behind the models do not hold true when fitted with real-world data. Even more problematically, the ELRF cannot account for environmental changes like inflation which are often observed in the status quo. Barnett and Zehnwirth conclude that a new set of models that contain parameters for not only accident year and development period trends but also payment year trends would be a more accurate predictor of loss development. This research applies the paper's ideas to data gathered by Company XYZ. The data was fitted with an adapted version of Barnett and Zehnwirth's new model in R, and a trend selection algorithm was developed to accompany the regression code. The final forecasts were compared to Company XYZ's booked reserves to evaluate the predictive power of the model.

This research aims to look at the lower level collegiate athletics, Intramural sports and club sports, in comparison to Division 1 varsity athletics to see how their sport lives differ and why they are still competing when the reward does not seem as grand as the Varsity athletics. The findings show that the socially ingrained aspect of sports is the reason that most lower level athletes keep competing.
