A Guide To Otoliths Of Minnesota Fishes, Baylor J. Short

Journal of Earth and Life Science

Investigations into the diet patterns of piscivores can provide crucial information on predator-prey relationships, population dynamics, and responses to changing ecosystems. However, digestive processes often remove or alter physical characteristics that are traditionally used to identify consumed fish. This problem has been addressed to some degree with advances in molecular technologies, although these methods can be costly and require specific training and equipment to do so. In contrast, bony structures such as otoliths, vertebrae, cleithra, and others frequently have morphologies that are unique among families, genera, and species. Because these structures are resistant to digestion, they can be used to …

Estimation Of Differential Pathlength Factor From Nirs Measurement In Skeletal Muscle, B. Koirala, A. Concas, A. Cincotti, Yi Sun, A. Hernández, M. L. Goodwin, L. B. Gladden, N. Lai

Electrical & Computer Engineering Faculty Publications

The utilization of continuous wave (CW) near-infrared spectroscopy (NIRS) device to measure non-invasively muscle oxygenation in healthy and disease states is limited by the uncertainties related to the differential path length factor (DPF). DPF value is required to quantify oxygenated and deoxygenated heme groups' concentration changes from measurement of optical densities by NIRS. An integrated approach that combines animal and computational models of oxygen transport and utilization was used to estimate the DPF value in situ. The canine model of muscle oxidative metabolism allowed measurement of both venous oxygen content and tissue oxygenation by CW NIRS under different oxygen delivery …

The Development And Evaluation Of A Method For Complete Collagenase I Digestion Of Bos Taurus Bone Samples, Reilly Price

Master of Science in Forensic Science Directed Research Projects

Current methods for processing aged forensic bone samples for DNA analysis involve pulverization and organic extraction, which further destroys already degraded DNA and uses large amounts of limited samples. Additionally, the success rates for this type of analysis vary widely as homogenization incorporates PCR inhibitors into the sample. Little research has explored how pulverization results in DNA damage in profiles obtained from skeletal remains. This study proposes an enzymatic digestion method to separate osteocytes from PCR inhibitors in the extracellular bone matrix to improve the quality and quantity of DNA isolated from aged bone samples. The technique described here used …

Assessment Of Forensic And Clinical Criteria Of Orbital Blowout Fractures For Use In Bioarchaeological Analysis, Dylan E. Ornot

Honors Undergraduate Theses

Orbital blowout fractures are a particular facial fracture occurring within the inner eye orbits of the face caused by blunt force trauma to the eyeball or the lower orbital rim. This fracture is common in modern clinical contexts due to physical assaults, but examining this fracture in skeletal material can also provide insights into the patterns of interpersonal violence within the fields of bioarchaeology and forensic anthropology. Issues with analyzing this fracture in skeletal material arise due to the clinical assessment practices of blowout fractures, where medical practitioners are highly focused on the soft tissue presentations of the fracture in …

Sex Differences In The Effects Of Cortisol On Muscle Characteristics: A Meta-Analysis, Natalie Bitetti

CMC Senior Theses

Background: Cortisol plays a central role in both muscle breakdown and growth. These effects are highly dependent on dose and interactions with other hormones. It is known that men and women show considerable differences in their muscle structure and physiology, which are largely driven by hormonal differences. Cortisol release patterns may also vary between the sexes, with current research showing considerable disagreement. The interplay between cortisol and muscle, two highly variable and sexually dimorphic factors, may prove to have different effects in males versus females.

Objective: This meta-analysis integrates existing research on sex differences in cortisol-muscle physiology with existing research …

Effects Of The Injury Recovery Process On Neuromuscular Activation In An Uninjured Ankle, Mark Tankersley

CMC Senior Theses

This study was conducted to observe the effects of changed activity levels due to a major lower extremity injury on ankle function in the uninjured leg. Neuromuscular activation in the Gastric Medialis (GAS) and Tibialis Anterior (TA), the muscles primarily responsible for movement at the ankle, was assessed in 8 athletes at the Claremont Colleges while walking on a flat surface, stepping up a 15º incline, and stepping up a 27º incline. Athletes were split into two groups based on injury condition: a “recovered” group (n=4) who had suffered a major lower extremity injury in the last two years in …

Occupational Therapy Students' Perceptions Of Participation In A Novel Educational Intervention To Learn Hand Anatomy, Christine Myers, Michael Cricchio, Rebecca Piazza, Morgan Yacoe

Journal of Occupational Therapy Education

Learning anatomy via cadaver dissection is considered a best practice in anatomical education. However, occupational therapy programs commonly use alternative or adjunct teaching methods when teaching anatomy. The purpose of this study was to investigate students’ perceptions of learning hand anatomy through participation in the Dell Hand Instructional Module (DHIM), a novel educational intervention incorporating an animated video series and a translucent, three-dimensional model of the hand. Participants attended one anatomical instructional session and one assessment session, completed a questionnaire about their experiences, and participated in a focus group. Participants agreed or strongly agreed that the DHIM made learning about …

How Hormonal Contraceptives Influence Injury In Female Athletes: A Systematic Review, Ashley V. Malvita

Honors Undergraduate Theses

Research indicates that female athletes have a higher risk of musculoskeletal injuries. Hormone fluctuations throughout the different periods of the menstruation cycle impacts the risk of injuries for women. Contraceptive use, most used in the form of an oral contraceptive pill, directly effects hormones and menstrual cycle related symptoms, with evidence of ameliorating some symptoms. Oral contraceptive use is suggested to influence musculoskeletal injuries in female athletes. However, there is little research and data that explores the direct relationship between oral contraceptive use and the injury rates of female athletes. Within this systematic review, five articles investigating this relationship fulfilled …
