Orthotic Satisfaction Survey, Jamie Bowman, Sarah Erickson Jan 2015

Orthotic Satisfaction Survey, Jamie Bowman, Sarah Erickson

Physical Therapy Scholarly Projects

The foot is made up of many bones, joints, and ligaments that help support the foot and body. When these structures are not properly aligned the appropriate biomechanics of the foot become compromised. Foot orthotics act as a conservative method of treatment to address some of the painful symptoms associated with these conditions. Common problems that have previously been addressed include plantar fasciitis, stress fractures, shin splints, flat feet, hallux valgus, and patellofemoral, heel and back pain.

In this study, we hope to indicate when and where orthotic use is indicated and what diagnoses benefit most when using orthotics as …

Proof-Of-Concept Of Environmental Dna Tools For Atlantic Sturgeon Management, Jameson Hinkle Jan 2015

Proof-Of-Concept Of Environmental Dna Tools For Atlantic Sturgeon Management, Jameson Hinkle

Theses and Dissertations

Abstract

The Atlantic Sturgeon (Acipenser oxyrinchus oxyrinchus, Mitchell) is an anadromous species that spawns in tidal freshwater rivers from Canada to Florida. Overfishing, river sedimentation and alteration of the river bottom have decreased Atlantic Sturgeon populations, and NOAA lists the species as endangered. Ecologists sometimes find it difficult to locate individuals of a species that is rare, endangered or invasive. The need for methods less invasive that can create more resolution of cryptic species presence is necessary. Environmental DNA (eDNA) is a non-invasive means of detecting rare, endangered, or invasive species by isolating nuclear or mitochondrial DNA (mtDNA) from the …

Influence Of Maternal Prior Life Adversity On The Psycho-Neuroendocrine-Immune Profile During Pregnancy, Karen J. Kotz Jan 2015

Influence Of Maternal Prior Life Adversity On The Psycho-Neuroendocrine-Immune Profile During Pregnancy, Karen J. Kotz

Dissertations

Pregnancy is accompanied by a multitude of physical and psychological changes. Adaptation to these changes through reduced anxiety and attenuated stress responsiveness is necessary across gestation and into the postpartum period for optimal maternal-infant health. In contrast, exposure to higher amounts of stressors during pregnancy can disrupt neuroendocrine-immune processes required for successful pregnancy outcomes. Evolving evidence demonstrates that exposure to adversity early in life has long-lasting effects on stress response systems that alter stress reactivity during adulthood. Given this evidence, it is posited that women who experience greater pre-pregnancy adversity during their childhood are at greater risk for negative maternal-infant …

Effects Of Aggregated Alpha-Synuclein On Cultured Neuronal Cells, David Freeman Jan 2015

Effects Of Aggregated Alpha-Synuclein On Cultured Neuronal Cells, David Freeman

Dissertations

α-synuclein dysregulation is a critical aspect of Parkinson's disease pathology. Recent studies have observed that α-synuclein aggregates are cytotoxic to cells in culture and that this toxicity can be spread between cells. However, the molecular mechanisms governing this cytotoxicity and spread are poorly characterized. Recent studies of viruses and bacteria, which achieve their cytoplasmic entry by rupturing intracellular vesicles, have utilized the redistribution of galectin proteins as a tool to measure vesicle rupture by these organisms. Using this approach, we demonstrate that α-synuclein aggregates can induce the rupture of lysosomes following their endocytosis in neuronal cell lines. This rupture can …

Extended Treatment Window Exists For Improving Sensorimotor Recovery Using Anti-Nogo A Immunotherapy In Adult Rats With Chronic Stroke Deficits, Katherine Marie Podraza

Dissertations

Stroke related death ranks as the fourth most common cause of mortality in the United States. Current therapeutic options following stroke are limited. One potential therapy involves the use of anti-Nogo-A immunotherapy post-stroke. Our laboratory has shown that the administration of this novel treatment results in sensorimotor recovery in adult and aged rats. This therapy has been shown to be efficacious when applied immediately, 24 hours, and 1 week post-stroke in rats with mild to moderate sensorimotor deficits. In addition, recent results suggest that administration of anti-Nogo-A immunotherapy up to 9 weeks after stroke still induces functional recovery and neuroanatomical …


Characterization Of The Effect Of Anti-Nogo-A Antibody Treatment On Sensorimotor Recovery After Traumatic Brain Injury, Stephen Nawara Jan 2015

Characterization Of The Effect Of Anti-Nogo-A Antibody Treatment On Sensorimotor Recovery After Traumatic Brain Injury, Stephen Nawara

Dissertations

Estimates indicate that over 5 million Americans are currently living with Traumatic Brain Injury (TBI) related disability. Much effort has been put into enhancing functional recovery with physical therapy and other rehabilitative approaches. These strategies are thought to function by facilitating the brain’s innate capacity for neuroregeneration and neuroplasticity. However, the success of these strategies may be limited due the presence of growth- and plasticity- inhibiting factors expressed in the adult brain.

The presence of the membrane protein Nogo-A has been associated with reduced neurite outgrowth in vitro, identifying it as one such molecule. In addition, rodents treated with antibodies …

Histopathology And Oxidative Stress Analysis Of Concomitant Misoprostol And Celecoxib Administration, Derek E. Murrell, James W. Denham, Sam Harirforoosh

Pharmacy Faculty Articles and Research

Nonsteroidal anti-inflammatory drugs (NSAIDs), non-selective or selective inhibitors of cyclooxygenase (COX-1 and -2), reduce pain and inflammation associated with arthritic diseases. Celecoxib, a COX-2-selective inhibitor providing decreased gastric injury relative to on-selective NSAIDs, is commonly prescribed. Misoprostol, a prostaglandin analog, supplements NSAID-inhibited prostaglandin levels. As concomitant celecoxib and misoprostol administration has been shown to intensify renal adverse effects, this article examined the influence of concomitant administration on hepatic histopathology, oxidative stress, and celecoxib concentration. On days 1 and 2, rat groups (n = 6) were gavaged twice daily (two groups with vehicle and two groups with 100 μg/kg misoprostol). From …
