The Singing Voice During The First Two Years Of Testosterone Therapy: Working With The Trans Or Gender Queer Voice, 2018 University of Colorado Boulder
The Singing Voice During The First Two Years Of Testosterone Therapy: Working With The Trans Or Gender Queer Voice, Tessa M. Romano
Voice and Opera Graduate Theses & Dissertations
In order to better serve singers who identify as trans men or gender queer, voice teachers must understand the vocal effects of hormone replacement therapy, specifically that of testosterone therapy. Testosterone therapy is the only type of hormone replacement therapy that permanently changes the voice and eventually results in a full octave drop or more of a person’s spoken fundamental frequency. Due to such a dramatic shift, the voice change process can be turbulent.
This dissertation is designed to educate both cis gender voice teachers and trans and gender queer singers on the process of vocal change during the ...
Cystic Fibrosis-Related Diabetes Is Caused By Islet Loss And Inflammation, 2018 Vanderbilt University Medical Center

Cystic fibrosis-related (CF-related) diabetes (CFRD) is an increasingly common and devastating comorbidity of CF, affecting approximately 35% of adults with CF. However, the underlying causes of CFRD are unclear. Here, we examined cystic fibrosis transmembrane conductance regulator (CFTR) islet expression and whether the CFTR participates in islet endocrine cell function using murine models of beta cell CFTR deletion and normal and CF human pancreas and islets. Specific deletion of CFTR from murine beta cells did not affect beta cell function. In human islets, CFTR mRNA was minimally expressed, and CFTR protein and electrical activity were not detected. Isolated CF/CFRD ...
The Effects Of Continuous Insulin Pump Therapy On Glycemic Control In Pregnant Type 1 Diabetics, 2017 Dominican University of California
The Effects Of Continuous Insulin Pump Therapy On Glycemic Control In Pregnant Type 1 Diabetics, Kimberly Kelsey
Senior Theses and Capstone Projects
Type 1 Diabetics have various ways of managing their diabetes that have been studied for their effectiveness. Pregnancy in the Type 1 Diabetic has been understudied. It is known that Diabetics in general have poorer pregnancy outcomes because of poor glycemic control. This coupled with the fact that the body needs 3-4 times more insulin as pregnancy comes to an end makes managing blood glucose levels challenging for diabetics (Lowdermilk, 2016, p. 689). For the Type 1 Diabetic, there are two main ways to control diabetes: multiple daily injections using at least two type of insulin and continuous subcutaneous insulin ...
Epigenetic Impact Of Endocrine Disrupting Chemicals On Lipid Homeostasis And Atherosclerosis: A Pregnane X Receptor-Centric View, Robert N. Helsley, Changcheng Zhou
Pharmacology and Nutritional Sciences Faculty Publications
Despite the major advances in developing diagnostic techniques and effective treatments, atherosclerotic cardiovascular disease (CVD) is still the leading cause of mortality and morbidity worldwide. While considerable progress has been achieved to identify gene variations and environmental factors that contribute to CVD, much less is known about the role of “gene–environment interactions” in predisposing individuals to CVD. Our chemical environment has significantly changed in the last few decades, and there are more than 100,000 synthetic chemicals in the market. Recent large-scale human population studies have associated exposure to certain chemicals including many endocrine disrupting chemicals (EDCs) with increased ...
Distortion In Body Schema: The Influence Of Body Fat And Mass On Perceptions Of Personal Size, Katarina Ann Ferrucci
Senior Projects Spring 2017
Obesity has been linked with a myriad of negative outcomes for both physical and mental health including feeding and eating disorders and cognitive impairments that affect perception of body size. Understanding the cognitive mechanisms and physiological factors that contribute to perception of body size may help us to comprehend how obesity impacts the construction and development of one’s mental body representations. Previous research by Scarpina, Castelnuovo, and Molinari (2014) suggests that, compared to those with a normal Body Mass Index, individuals with a BMI greater than 30 (obese) not only inaccurately estimate tactile and mental distances on their own ...
Sugar Consumption Alters Perception Of And Response To Stress In Undergraduate Students: Understanding The "Freshmen Fifteen", 2016 Union College - Schenectady, NY
Sugar Consumption Alters Perception Of And Response To Stress In Undergraduate Students: Understanding The "Freshmen Fifteen", Katherine M Keever
Psychological stress is a common part in everyday life that directly affects the body through the nervous system and neuroendocrine hormones. A perceived stressor leads to the activation of the hypothalamic-pituitary-adrenal (HPA) axis, and the synthesis and release of the glucocorticoid hormone cortisol from the adrenal cortex. Studies have linked the release of cortisol during high-stress periods to an increased intake of sugary and fatty foods, consistent with a suspected glucocorticoid-metabolic-brain- negative pathway, with high sugar consumption leading to lower stress and subsequently cortisol levels. In this study, undergraduate students’ diets were supplemented with either a high sugar drink or ...
Point Mutations Of The Putative Follitropin Receptor Caveolin Interaction Motif Do Not Disrupt Receptor Function, 2016 Union College - Schenectady, NY
Point Mutations Of The Putative Follitropin Receptor Caveolin Interaction Motif Do Not Disrupt Receptor Function, Stanley Soroka
Human follicle stimulating hormone (hFSH) is a hormone found in humans that is synthesized and secreted by the anterior pituitary and targets the ovaries and testes. This specificity of targeting is accomplished by the interaction of hFSH with its receptor (hFSHR) on target cells. hFSHR is a G protein-coupled receptor that localizes to domains in the cell membrane known as lipid rafts. The mechanism of translocation of the hFSHR into lipid rafts is unknown. Our hypothesis is that translocation occurs through interaction of hFSHR with the protein caveolin via a specific sequence in the hFSHR; a putative caveolin interaction motif ...

College of Pharmacy (TUC) Publications and Research
The aim of this study was to simplify, improve and validate quantitative measurement of the mitochondrial membrane potential (ΔψM) in pancreatic β-cells. This built on our previously introduced calculation of the absolute magnitude of ΔψM in intact cells, using time-lapse imaging of the non-quench mode fluorescence of tetramethylrhodamine methyl ester and a bis-oxonol plasma membrane potential (ΔψP) indicator. ΔψM is a central mediator of glucose-stimulated insulin secretion in pancreatic β-cells. ΔψM is at the crossroads of cellular energy production and demand, therefore precise assay of its magnitude is a valuable tool to study how these processes interplay in insulin secretion ...

Bilateral renal cyst formation is the main feature of autosomal dominant polycystic kidney disease (ADPKD). We and other laboratories have previously shown that cystlining epithelia of kidneys from ADPKD patients are characterized by polyploidy. In this report, we show that endothelia from the renal capillary beds of two ADPKD patients are also polyploidy. Spectral karyotyping study further confirms our flow cytometry analyses. We suggest that polyploidy may be used as a potential cellular marker in ADPKD.

Mutations in either polycystin-2 (PC2) or polycystin-1 (PC1) proteins cause severe, potentially lethal, kidney disorders and multiple extrarenal (including brain) disease phenotypes. PC2, a member of the transient receptor potential channel superfamily, and PC1, an orphan membrane receptor of largely unknown function, are thought to be part of a common signaling pathway. Here, we show that in rat sympathetic neurons and kidney cells, coassembly of full-length PC1 with PC2 forms a plasmalemmal ion channel signaling complex in which PC1 stimulation simultaneously activates PC2 ion channels and G(i/o)-proteins. PC2 activation occurs through a structural rearrangement of PC1, independent ...

Integrated medical curricular changes are altering the historical regional anatomy approach to abdominal dissection. The renal system is linked physiologically and biochemically to the cardiovascular and respiratory systems, yet anatomist often approach the urinary system as part of the abdomen and pelvic regions. As part of an integrated curriculum, the renal system must be covered relatively quickly after the thorax in the cadaver lab, often without the opportunity to fully appreciate the rest of the abdominal contents. This paper provides dissection instructions that follow the one of the historical surgical approaches for nephrectomy, including preservation of the posterior abdominal wall ...

In the last decade, researchers have gained a greater understanding of the pathophysiologic mechanisms of type 2 diabetes as a chronic and progressive disease. One of the more recent treatment targets is the kidney. The kidneys become maladaptive in diabetes by increasing the reabsorption of glucose above the normal physiologic renal threshold. This discovery has led to the development of the sodium/glucose cotransporter 2 inhibitors (SGLT2). These agents readjust the renal threshold for glucose reabsorption to a lower level and decrease glucose reabsorption, while increasing urinary glucose when the glucose is above the renal threshold and subsequently lowering plasma ...

Activation of dopamine receptor type-5 (DR5) has been known to reduce systemic blood pressure, most likely by increasing renal vasodilation and enhancing natriuresis in the kidney. However, the mechanism of DR5 in natriuresis and vasodilation was not clearly known. We have previously shown that DR5 is localized to primary cilia of proximal renal epithelial and vascular endothelial cells. We here show that selective activation of DR5 specifically induces calcium influx only in the primary cilia, whereas non-selective activation of dopamine receptor induces calcium fluxes in both cilioplasm and cytoplasm. Cilia-independent signaling induced by thrombin only shows calcium signaling within cytoplasm ...

Ideology Masquerading As Science: The Case Of Endocrine Disrupter Screening Programmes, Troy Seidle
Troy Seidle, Ph.D.
The global move to develop novel testing methods and strategies to identify suspected endocrine disrupting chemicals offers a unique opportunity to move away from traditional animal testing paradigms in this new area of regulatory concern. Regrettably, the programmes under development, both in the USA and internationally through the OECD, have thus far failed to consider in vitro and other nonanimal test methods as more than “pre-screening” or “priority-setting” tools in a larger, animal-based testing strategy. Validation efforts to date have focused almost exclusively on the modification of existing animal tests to detect “endocrine effects”, with no demonstrable effort to promote ...

Non-alcoholic fatty liver disease is prevalent in human obesity and type 2 diabetes, and is characterized by increases in both hepatic triglyceride accumulation (denoted as steatosis) and expression of pro-inflammatory cytokines such as IL-1beta. We report here that the development of hepatic steatosis requires IL-1 signaling, which upregulates Fatty acid synthase to promote hepatic lipogenesis. Using clodronate liposomes to selectively deplete liver Kupffer cells in ob/ob mice, we observed remarkable amelioration of obesity-induced hepatic steatosis and reductions in liver weight, triglyceride content and lipogenic enzyme expressions. Similar results were obtained with diet-induced obese mice, although visceral adipose tissue macrophage ...

The Role Of Estrogen And Estrogen Analogues In Friedreich’S Ataxia Cytoprotection, 2014 University of North Texas Health Science Center of Fort Worth
The Role Of Estrogen And Estrogen Analogues In Friedreich’S Ataxia Cytoprotection, Timothy E. Richardson
Theses and Dissertations
Friedreich’s ataxia (FRDA) is the most common form of inherited ataxia in the world, affecting roughly 1:50,000 people in the United States. It is inherited in an autosomal recessive manner due to a GAA trinucleotide repeat expansion in the first intron of the FXN gene on chromosome 9q13-21, causing gene silencing and a functional absence of the mitochondrial-localizing protein frataxin. The frataxin protein is responsible for the assembly of iron-sulfur centers in mitochondrial proteins, including the electron transport chain complex I-III, heme synthesis, as well as removing iron from around the mitochondria, preventing the formation of reactive ...

Dopamine plays a number of important physiological roles. However, activation of dopamine receptor type-5 (DR5) and its effect in renal epithelial cells have not been studied. Here, we show for the first time that DR5 is localized to primary cilia of LLCPK kidney cells. Renal epithelial cilia are mechanosensory organelles that sense and respond to tubular fluid-flow in the kidney. To determine the roles of DR5 and sensory cilia, we used dopamine to non-selectively and fenoldopam to selectively activate ciliary DR5. Compared to mock treatment, dopamine treated cells significantly increases the length of cilia. Fenoldopam further increases the length of ...

Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders affecting reproductively aged women. Women with PCOS and ewes prenatally exposed to testosterone (T) show similar reproductive and metabolic defects, including anovulatory dysfunctions stemming from abnormal gonadotropin releasing hormone (GnRH) secretion and insulin resistance. For this dissertation, I examined the effects of prenatal T treatment on androgen receptor (AR) and insulin receptor (IR) expression with the reproductive and metabolic neurons of the hypothalamus, the ARC KNDy (co-expressing kisspeptin, neurokinin B/dynorphin), AgRP (agouti-related peptide) and proopiomelanocortin (POMC) neurons, and the preoptic area (POA) kisspeptin neurons, and the GnRH ...

The gonadotropin-releasing hormone (GnRH) neurons in the hypothalamus represent the final common output in the central control of reproduction. GnRH secretion is modulated indirectly by steroid feedback action of gonadal steroids on afferent interneurons. In recent years, the neuropeptide, kisspeptin, has emerged as a key mediator of steroid feedback onto GnRH neurons and the reproductive system. Kisspeptin neurons located in the preoptic area (POA) mediate estradiol (E2) positive feedback leading to the preovulatory surge, and kisspeptin cells in the arcuate nucleus (ARC) have been shown to mediate the negative feedback actions of E2 on pulsatile GnRH secretion. ARC kisspeptin neurons ...
