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 …
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 …
Effectiveness Of Visual Representations In Undergraduate Human Anatomy And Physiology I & Ii, Mary Agnes Mestayer
Effectiveness Of Visual Representations In Undergraduate Human Anatomy And Physiology I & Ii, Mary Agnes Mestayer
Honors Theses
The objective of this project was to explore intersections between student preferences and student performance on anatomical visual representations in Human Anatomy and Physiology I and II. Visual representations are a critical resource for the formation of relationships between function and structure furthermore; students interpret these representations uniquely based on specific factors (learning objective, prior knowledge, the diagram studied, etc.). Phase I of this project gathered undergraduate responses to ten Likert-style questions on their opinions on diagrams and their use in the A&P classroom. Phase II of this project presented participants with twelve manipulated diagrams sourced from three diagram with …
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, …
Use Of Small Molecule Fanconi Anemia Pathway Inhibitors As Sensitizing Agents To Laromustine., Sam W. Marchant
Use Of Small Molecule Fanconi Anemia Pathway Inhibitors As Sensitizing Agents To Laromustine., Sam W. Marchant
Honors Theses
Laromustine is an experimental chemotherapeutic sulfonyl hydrazine prodrug shown in clinical trials to be effective against acute myeloid leukemia. The mechanism of action of laromustine involves interstrand crosslinking, via chloroethylation, and enzyme inhibition, caused by carbamoylation. The work described herein aims to investigate whether inhibition of the replication-dependent interstrand crosslink repair Fanconi Anemia pathway further sensitizes cells to laromustine. By measuring metabolic activity immediately after drug exposure, we find laromustine to be equally as cytotoxic towards Fanconi Anemia deficient and wild type cells. However, through clonogenic assays we show Fanconi Anemia mutations sensitize cells to laromustine’s anti-proliferative effect. Furthermore, we …
