Health and Nutritional Sciences Faculty Publications

Objectives: The purpose of this study was to determine the effect of sports participation on cortical bone in the tibia. Methods: 53 female collegiate athletes (25 cross-country, 16 soccer, and 12 volleyball) and 20 inactive controls had the left distal 20% tibia scanned by pQCT. Cortical volumetric BMD (vBMD) was measured within the cortical shell at the anterior, posterior, medial, and lateral regions and standard deviations were calculated. Results: Total vBMD was greater in the control group (1161±5 mg/mm3) than each of the sports (p<0.05). Soccer players (1147±5 mg/mm3) had greater vBMD than volleyball players (1136±7 mg/mm3) (p<0.05), but similar to cross-country runners (1145±5 mg/mm3). Cortical thickness was greatest in soccer players (4.1±0.1 mm), while cross-country and control subjects (3.8±0.1 mm) had greater thickness than volleyball players (3.4±0.1 mm)(p<0.05). Periosteal circumference was greater in volleyball players (71±1.4 mm) than soccer, cross-country, and control subjects (68±0.9, 69±0.8, and 66±1 mm, respectively; all, p<0.05). vBMD variation within the cortical shell was greater among control subjects (70±6 mg/cm3) than each of the athlete groups, with soccer players having lower variation than cross country runners (within-in person SD 36±6 mg/cm3 and 54±5 mg/cm3 respectively; p<0.05). Conclusion: These results indicate bone geometry and distribution within the cortical shell of the tibia …

Racemization Of Amino Acids In Teeth For The Determination Of Age, Andrea Lee Toll

Masters Theses & Specialist Projects

Instrumental to forensic investigations is the ability to identify unknown human remains providing key evidence to criminal cases, resolution to missing persons, and assistance in mass or natural disasters. Identification of remains in an effort to determine age is an area of forensics that has received considerable attention. Traditional methods in age determination such as morphology are often biased, antiquated, and frequently result in a large margin of error. Conversely, the emergence of new forensic techniques provide promise to reduce the margin of error in determining age. One such technique has focused on relating the extent of amino acid racemization …

Electromyography (Emg) Biofeedback Training In Music Performance: Preventing And Reducing Musculoskeletal Pain In Musicians, Carolyn Yarbrough

Scripps Senior Theses

Musicians are a high-risk occupational group for musculoskeletal disorders. Often manifesting in muscle tension, pain and paresthesia, musculoskeletal disorders can drastically affect comfort, mentality and endurance while performing. This study sought to examine the effects of electromyography (EMG) biofeedback training in reducing musculoskeletal symptoms in music performance. The subjects were university-level violinists and cellists. Over a period of 2-4 weeks, all participants underwent EMG biofeedback training while performing their instrument using audio feedback. No significant results were found, but patterns of decreased muscle tension and increased performance comfort and endurance were observed.

Submicron Bioactive Glass Tubes For Bone Tissue Engineering, Jingwei Xie, Eric Blough, Chi-Hwa Wang

MIIR Faculty Research

Herein we describe a method to fabricate submicron bioactive glass tubes using of sol-gel and co-axial electrospinning techniques for applications in bone tissue engineering. Heavy mineral oil and gel solution were delivered by two independent syringe pumps during the co-axial electrospinning process. Subsequently, submicron bioactive glass tubes were obtained by removal of poly(vinyl pyrrolidone) (PVP) and heavy mineral oil via calcination at 600 °C for 5 h. Tubular structure was confirmed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM) imaging. We examined the bioactivity of submicron bioactive glass tubes and fibers and evaluated their biocompatibility taking electrospun poly(ε-caprolactone) …

Objective. Our objective was to compare the osteoclastogenic capacity of peripheral blood mononuclear cells (PBMCs) from patients with osteoarthritis (OA) to that of PBMCs from self-reported normal individuals.

Methods. PBMCs from 140 patients with OA and 45 healthy donors were assayed for CD14⁺ expression and induced to differentiate into osteoclasts (OCs) over 3 weeks in vitro. We assessed the number of the OCs, their resorptive activity, OC apoptosis, and expression of the following cytokine receptors: receptor activator of nuclear factor κB (RANK), interleukin-1 receptor type I (IL-1R1) and IL-1R2. A ridge logistic regression classifier was developed …

Gene Therapy In The Cornea: 2005--Present, Rajiv R. Mohan, Jonathan C. K. Tovey, Ajay Sharma, Ashish Tandon

Pharmacy Faculty Articles and Research

Successful restoration of vision in human patients with gene therapy affirmed its promise to cure ocular diseases and disorders. The efficacy of gene therapy is contingent upon vector and mode of therapeutic DNA introduction into targeted cells/tissues. The cornea is an ideal tissue for gene therapy due to its ease of access and relative immune-privilege. Considerable progress has been made in the field of corneal gene therapy in last 5 years. Several new gene transfer vectors, techniques and approaches have evolved. Although corneal gene therapy is still in its early stages of development, the potential of gene-based interventions to treat …

The PEI-DNA polyplex formation was confirmed through gel retardation assay. Human corneal fibroblasts (HCFs) were …

Short-Term Plasticity At The Schaffer Collateral: A New Model With Implications For Hippocampal Processing, Andrew Hamilton Toland

Dissertations and Theses

A new mathematical model of short-term synaptic plasticity (STP) at the Schaffer collateral is introduced. Like other models of STP, the new model relates short-term synaptic plasticity to an interaction between facilitative and depressive dynamic influences. Unlike previous models, the new model successfully simulates facilitative and depressive dynamics within the framework of the synaptic vesicle cycle. The novelty of the model lies in the description of a competitive interaction between calcium-sensitive proteins for binding sites on the vesicle release machinery. By attributing specific molecular causes to observable presynaptic effects, the new model of STP can predict the effects of specific …
