Mtdna Heteroplasmy In Hair Shafts Versus Buccal Swabs For Forensic Applications, Sara R. Bodnar

Graduate Theses, Dissertations, and Problem Reports (ETD)

Mitochondrial DNA (mtDNA) analysis has several forensic applications such as criminal investigations, identification of human remains, and missing person investigations. It is also the only type of DNA that is available from certain sample types such as hair shafts. The presence of mtDNA heteroplasmy within and between tissue types can lead to mtDNA sequence differences when comparing samples originating from the same individual. Studies on mtDNA heteroplasmy are increasingly being carried out for their implications in forensic interpretation of mtDNA sequences. Specifically, mtDNA in buccal swabs compared to hair samples from one individual may show differences in sequence due to …

Feed Conditioning Effects On Enzymes, Amino Acids, And Subsequent Broiler Performance, Elizabeth Ann Lynch

Graduate Theses, Dissertations, and Problem Reports (ETD)

There are many things that can be done to improve broiler performance including, but not limited to, pelleting, proper Lys inclusion, and exogenous enzyme supplementation. Pelleting has the ability to improve feed form, reduce wastage, improve bird performance metrics, and decrease pathogens within the feed. Pathogen reduction can be further reduced by hygienic pelleting practices which include an increase in temperature or retention time within a conditioner or hygieniser. However, hygienic pelleting can degrade valuable AA and enzymes (more specifically for the current thesis research Lys and phytase) and make them unavailable to the animal. Supplementing Lys to account for …

Relation Of Child Feeding Behaviors & Caregiver Qualities To Adherence To Nutritional Therapy In Type 1 Diabetes Management, Corrine N. Ahrabi-Nejad

Graduate Theses, Dissertations, and Problem Reports (ETD)

Type 1 diabetes (T1D) is a chronic illness, typically diagnosed within childhood, that affects the ability of the pancreas to produce insulin. Significant daily self-management behaviors are required to maintain metabolic control for patients with T1D. Nutritional therapy, including adequate intake of macronutrients, is one self-management behavior necessary to optimize health. Adherence to such nutritional guidelines is associated with improved glycemic control, decreased instances of acute health complications (e.g., hyperglycemia, hypoglycemia), and can also prevent insulin resistance. Despite the critical importance of nutritional therapy, adherence to these guidelines remains low within pediatric populations. Therefore, it is important and necessary to …

Playing-Related Medical Injuries And Health Conditions In Collegiate Saxophonists: A Survey Of Saxophonists In North American Universities, Michael Anne Tolan

Graduate Theses, Dissertations, and Problem Reports (ETD)

When compared to other areas of musical performance, medical research on the performing arts is limited when it comes to studies on woodwind players, particularly saxophonists. The gap in research may be attributed to the circumstances surrounding selection processes and identifying subjects for study. For example, saxophonists are not salaried professionals in orchestras, which are commonly pooled for medical research. Establishing contact with saxophonists to conduct studies can prove difficult due to the wide range of genres that utilize the saxophone. Some issues may also be attributed to research methodology.
