Description
For this project, I analyzed both the amount of overuse injuries or repetitive stress injuries occurring in college baseball and tried to understand why they were happening so frequently. I interviewed over a dozen people to get thoughts and messages on the subject from a variety of people from current college players, to Major League players, to current college coaches. While I spent the majority of the project working on the research and interviews of how these injuries effect college athletes, I always spent time speaking with journalists about the proper ways they go about reporting on injuries, especially those within college athletes. I found data that showed that the average rate of fastballs in Major League Baseball is going up and that is indirectly affecting the way in which players and specifically pitchers are learning to play as they go through college baseball. I got valuable perspective on how the game changing is affecting the injuries that are so common today. The most common occurring repetitive stress issue in baseball has been happening most with pitchers so much of the project is tailored toward the views of some of the best pitchers in college baseball. I found out how college pitchers are taking care of their bodies and using the offseason to help regain strength. Why do some pitchers not take as long an offseason as others? How intense is the pressure to stay healthy in college, as many of these athletes are pursuing professional baseball? What is the mental toll these student-athletes have on a day-to-day basis? All these questions and more are answered in the paper. Included in the long-form paper are all of the full transcripts from the interviews with players, coaches, trainers, doctors, and reporters.

Description
Across large areas of eastern and midwestern North America, a severe reduction in multiple populations of bat species has been observed as the result of the emerging fungal disease, white-nose syndrome (WNS). WNS is caused by a psychrophilic (i.e. cold loving) fungus, Pseudogymnoascus destructans (Pd), that invades the skin of bats during hibernation. Recent studies have shown that during hibernation, bats have decreased immune system activity which would suggest increased susceptibility to infection. Antimicrobial peptides (AMPs) are an important component of the innate immune system and are expressed constitutively within all tissues that serve as barriers against infection. Killing pathogens at the level of the skin could prevent the need for more complex immune responses likely inhibited during hibernation, and therefore AMPs could be critical in combating infection by Pd and reducing population loss of susceptible bat species. In this investigation, the fungicidal activity of commercially available AMPs derived from the skin of multiple taxa, including amphibians, catfish, and humans were compared in order to study immunity at the level of the skin. Additionally, our aim was to create optimal methods for a low-cost antimicrobial-assay protocol that would provide quantitative results. We found that killing abilities at various concentrations of dermaseptin S-1 against Ca ATCC 10231 were consistent with literature values, while our values for magainin 2 and parasin 1 were far from the values previously recorded by other studies. It is possible that some differences can be accounted for by the difference in antimicrobial assay procedures, but our findings suggest potential differences to the well-known killing abilities of certain peptides nonetheless. Overall, the protocol established for the antimicrobial assays using serial dilutions and Sabouraud Dextrose plates was successful.

Description
White-nose syndrome (WNS) is a cutaneous fungal infection caused by Pseudogymnoascus destructans (Pd) which was first observed in the United States in 2006. Pd infects bats during hibernation and leads to the development of cutaneous lesions and behavioral changes that can result in the animal's death. This study generated the first complete bat skin proteome for the WNS resistant gray bat (Myotis grisescens) to optimize sample preparation methods and identify immune proteins that may signal resistance. Wing tissue was collected from a female gray bat and processed in a Barocycler using 4M or 8M urea followed by an in-gel trypsin digestion of pooled samples and processing of separate samples without digestion specifically to capture and identify small antimicrobial peptides. Both undigested and digested samples were analyzed using a Thermo Fisher LTQ Orbitrap Velos mass spectrometer and interpreted using PEAKS software. A total of 29 immune proteins were identified including the antimicrobial peptide dermcidin. This method will be applied to a larger range of samples from five species variably impacted by WNS to compare skin proteomes with the aim of identifying immune proteins that are responsible for resistance at the barrier where Pd invades.
