An Investigation Of Chronic Pain As A Much-Neglected Symptom Of Hypermobile Ehlers-Danlos Syndrome, Sydney Collins
An Investigation Of Chronic Pain As A Much-Neglected Symptom Of Hypermobile Ehlers-Danlos Syndrome, Sydney Collins
Honors Theses
Ehlers Danlos Syndrome is a group of heritable loose connective tissue disorders with 13 distinguished subtypes. The hypermobile type of Ehlers Danlos Syndrome (hEDS) is the most common subtype and is caused by a genetic mutation that leads to defective collagen fibrils. This leads to joint instability and hypermobility, skin elasticity, widespread pain, fatigue, and generalized tissue fragility. Chronic pain is reported to be a symptom in as high as 92% of the hEDS population (Voermans et al., 2010); despite this prevalence, there is a significant lack of research, awareness, and treatment standardization regarding pain in hEDS. This literature review …
The Impacts Of Aging, Sedentarism, And Exercise On Neurotrophic Factor Expression And Innervation In The Heart And The Effects Of Treatment With Α-Cgrp On Heart Function, Gabriel Almeida Alves
The Impacts Of Aging, Sedentarism, And Exercise On Neurotrophic Factor Expression And Innervation In The Heart And The Effects Of Treatment With Α-Cgrp On Heart Function, Gabriel Almeida Alves
Dissertations
Neurotrophic factors (NFs) are important molecules responsible for development, differentiation, regeneration, and maintenance of new and mature neurons. Neurotrophic factors act as neurocytokines and may assist with the regulation of axonal and dendritic arrangements and synaptic plasticity between neurons themselves or with other non-neural target tissues. In this study, we analyze the levels of two NFs: glial cell line-derived neurotrophic factor (GDNF) and nerve growth factor (NGF). Cardiomyocytes produce these neurotrophic factors which assist with the innervation pattern of the heart. The heart is innervated by the two branches of the autonomic nervous system; namely the sympathetic nervous system and …
Environmental Justice Analysis Of Drinking Water Policies In Michigan Cities, Annika Paldan
Environmental Justice Analysis Of Drinking Water Policies In Michigan Cities, Annika Paldan
Honors Theses
This thesis examined environmental justice aspects of drinking water policies in four cities across Michigan: Flint, Birmingham, St. Joseph, and Benton Harbor. An overview of the history of the environmental justice movement, environmental racism, and drinking water policies provided the basis for a four-part evaluative criterion to assess environmental justice components at the municipal level. These criteria include (1) housing tenure, (2) age, size, and service line composition of the infrastructure, (3) public participation in the policy process, and (4) emergency management of the city. Findings indicate that environmental justice has come a long way, with cities now incorporating components …
Literature Review Of Human Hdr Syndrome With Gata3 Haplo Insufficiency, Olivia Ambursley-Gries
Literature Review Of Human Hdr Syndrome With Gata3 Haplo Insufficiency, Olivia Ambursley-Gries
Honors Theses
This literature mining project is regarding mutations that cause hearing loss in patients with human hypo parathyroid, deafness, and renal dysplasia (HDR) syndrome caused by a mutation in the GATA3 gene. The disease is unique; not all diagnosed individuals present with all symptoms of the triad. Van Esh et al. found that the haploinsufficiency of the GATA3 is found on chromosome 10p14-p15 (ref.1). The focus of this work is to condense the literature on GATA3 haploinsufficiency correlating to human HDR syndrome. Due to the lack of global healthcare access, it can be assumed that many cases remain undiagnosed; 180 have …
Retinal Regeneration In A Genetic Mouse Model Of Glaucoma, Joshua Paris
Retinal Regeneration In A Genetic Mouse Model Of Glaucoma, Joshua Paris
Masters Theses
Glaucoma is a degenerative retinal disease characterized by progressive loss of retinal ganglion cells (RGCs). Previous studies have shown that application of a specific α7 nicotinic acetylcholine receptor agonist, PNU-282987 (PNU), onto the murine retina induces neurogenesis of numerous retinal cell types, including RGCs. The aim of this study is to characterize the short-term and long-term effects of PNU in a glaucoma model. The effects of PNU were analyzed in a DBA/2J mouse model that auto-induces a glaucoma-like condition in adulthood. These mice manifest an elevated intraocular pressure (IOP) starting at 6 months, followed by loss of RGCs. To assess …
How Gata3 Affects Neuronal Survival In The Inner Ear, Hiba Ahmad
How Gata3 Affects Neuronal Survival In The Inner Ear, Hiba Ahmad
Honors Theses
Broadly speaking, Gata3 is a transcription factor involved in neurosensory specification and hair cell differentiation. Previous studies have shown that Gata3 null mutants do not develop neurons, so Gata3 appears to be necessary for neuronal survival. To better understand the role of Gata3 in spiral ganglion neurons of the inner ear, a Neurod1-cre model was used to conditionally knock out Gata3 at E9-E9.5, the timepoint when neuroblasts first begin to delaminate from the otic placode. The mutants used in this study were Nd1-cre: Gata3 f/f mutants. In situ was performed to determine gene expression within the cochlea, and immunohistochemistry was …
Crayfish And Climate Change: How The Growing Acidity Of Freshwater Lakes, Streams, And Ponds Negatively Impact The Nervous System Of Crayfish, Lauren Irmen
Honors Theses
The nervous system of crayfish, a freshwater crustacean, is largely regulated by the flow of calcium (Ca2+) ions in a cell across a concentration gradient that produces electrical impulses and controls movement (Krause et al., 1998). Crayfish obtain Ca2+ from their external aquatic environment. Therefore, rapid changes in the concentration of Ca2+ in freshwater environments may cause negative impacts to the neural system of crayfish and subsequently the freshwater food chain. These impact of altered Ca2+ levels may create hyperactive or hypoactive movement due to over-, under-stimulation, respectfully in the skeletal muscle of the crayfish, …
Regenerative Rehabilitation And Genomics: Implications For Occupational Therapy, John V. Rider
Regenerative Rehabilitation And Genomics: Implications For Occupational Therapy, John V. Rider
The Open Journal of Occupational Therapy
The completion of the human genome project has paved the way for health care practitioners to use genetic and environmental information to tailor medical treatment. This innovative approach to health care is rapidly evolving, and occupational therapists need to be aware of the impact it will have on future practice. Regenerative rehabilitation is a product of knowledge and techniques from the fields of rehabilitation and regenerative medicine with the common goal to restore function. Occupational therapists have the potential to play a significant role in regenerative rehabilitation research and implementation. The purpose of this article is to (a) increase understanding …
Patella Resection In Total Knee Arthroplasty: An Analytical Comparison Of Three Techniques, Kelsey Cushway
Patella Resection In Total Knee Arthroplasty: An Analytical Comparison Of Three Techniques, Kelsey Cushway
Research Day
Patella resection, as a routine component of TKA, can be both difficult to plan and difficult to execute. The primary purpose of this study was to evaluate the repeatability of three unique patellar resection techniques used in total knee arthroplasty. The secondary purpose of this study was to establish whether different surgical techniques were able to reproduce preoperative plans made by each surgeon. We used radiographic measurements to evaluate patellar thickness and patellar cut angle preoperatively and postoperatively. Three techniques (45 cases in total) were evaluated, revealing qualitative differences between surgical techniques and significant quantitative differences between average patellar thickness …
