Activation Dependent Function Of Transient Receptor Potential Canonical 3 In Neurosecretion, Sunitha Bollimuntha

Theses and Dissertations

Transient receptor potential canonical 3 (TRPC3), a non-selective Ca 2+-permeable cation channel, is a member of the TRP superfamily of ion channels. The mode of activation of TRPC3 is governed by a cascade of Phospholipase C (PLC) mediated signaling events, following G-protein coupled receptor (GPCR) or tyrosine kinase receptor activation, resulting in endoplasmic reticulum (ER) Ca2+ store depletion. This very store depletion triggers the activation of plasma membrane TRPC3 and hence they are termed as receptor operated or store operated cation channels. In addition to the receptor mediated activation of TRPC3, an alternate mode of channel activation has been described, …

Gender And Physical Abuse History As Predictors Of Adult Anxiety Reactions To A Public Speaking Evaluative Stress Paradigm, Brian Keith Moe

Theses and Dissertations

Much research has been conducted regarding the long-term effects of childhood maltreatment. Childhood Physical Abuse (CPA), Childhood Sexual Abuse (CSA), and Observed Domestic Abuse (ODA) have been linked to a variety of negative outcomes with effect sizes typically modest in size. This research base has been difficult to interpret because of study differences in the operationalization of abuse and the varied outcome measures that have been employed from study to study. The present study was designed to elicit participant emotional (state/trait anger and anxiety) and physiological (heart rate) reactions to a public speaking stress induction task. A sample of 98 …

Development And Application Of Fluorescent Silica Nanoparticles For Bioanalysis, Yuhui Jin

Theses and Dissertations

In this dissertation, fluorescent silica nanoparticles (NPs) have been successfully developed to improve the performance of bioanalysis. In the first step, the sizes of silica NPs were precisely controlled by changing the organic solvent in the reverse microemulsion method. The size of the NPs can be continuously tuned from 20 to 100 nm. Then, multicolored fluorescent silica NPs were developed with controllable fluorescence properties by manipulating the properties of the dopants. To this end, both the excitation and emission spectra of the dopants could be tuned by conjugating multiple fluorophores through either avidin-biotin linkage or polylysine. With desirable sizes and …

Hippocampal Based Spatial Memory, Antioxidant Defense And Neurogenesis In Long-Living Ames Dwarf Mice, Sunita Sharma

Theses and Dissertations

The US Census Bureau projects that there Will be 71.5 million people over the age of 65 by 2030. One of the most significant problems is that the elderly population suffers from age-associated cognitive impairment. The hippocampus is one identified brain region known to be vulnerable to aging and is associated with a decline in growth hormone/insulin like growth factor-1 (GH/IGF-1), and an increase in oxidative stress and neuronal loss. The Ames dwarf mouse is a long-living animal that is growth hormone deficient and thus, lacks peripheral IGF-1. Ames mice have enhanced antioxidant protection in the peripheral system but the …

A Macroscopic Study Of The Electrochemical Modeling Parameters Of A 6 Kw Pem Electrolyzer, Christian Y. F. Biaku

Theses and Dissertations

This study examined the thermodynamic electrochemistry of the process of proton exchange membrane electrolysis of a 6 kW electrolyzer manufactured by Proton Energy Systems. Each modeling parameter was examined based on the definition and the theories which characterize their behavior using experimental data generated at the University of North Dakota hydrogen laboratory. The exchange current densities, membrane resistance and charge transfer coefficients were examined at both electrodes for their temperature dependence. While most of the temperature studies revealed an Arrhenius behavior, the exchange current density at the anode showed a deviation. This leads me to believe that stacking cells together …

Phosphorylation Of The Type Iα Regulatory Subunit Of Camp -Dependent Protein Kinase., Karen Mae Boeshans

Theses and Dissertations

The mechanism by which the type la regulatory subunit (RIa) of cAMP-dependent protein kinase (PKAI) is localized to cell membranes is unknown, however, RIa may be localized through hydrophobic interaction with membrane lipids. To determine if post-translational lipid modification of RIa is important for membrane association, both beef skeletal muscle cytosolic RI and beef heart membrane-associated RI were characterized by electrospray ionization mass spectrometry. Total sequence coverage was 98% for both the membrane and cytosolic forms of RI after digestion with trypsin or AspN protease. Sequence data indicated that membrane-associated and cytosolic forms of RI were the same RIa gene …

Negotiating The Gray Areas Of Ethical Decision Making: Deaf Therapists Working In The Deaf Community, Denise Alice Thew

Theses and Dissertations

Deaf and Hard-of-Hearing psychologists, who provide services to the Deaf and Hard-of-Hearing community, face unique dilemmas when dealing with overlapping relationships. Similar to psychologists from other small or rural communities, dual relationships are generally unavoidable. The ethical guidelines for psychologists do not provide for the exceptional struggles that many Deaf therapists face in this regard.

This study was conducted to explore the decision-making patterns that Deaf therapists have used in negotiating nonsexual, multiple relationships with clients. Ten taped interviews were conducted to collect preliminary data on the overlapping relationship dilemmas of participants who are Deaf, licensed therapists and have been …

Sense Of Connection And Learning In Traditional And Online Courses At A Rural-Serving Community College, Jayne M. S. Kiner

Theses and Dissertations

The purpose of this study was to establish an overall measurement for student sense of classroom community in terms of the theoretical dimensions of emotional connection, and needs fulfillment (learning). Further intent was to determine the nature of differences, if they exist, between delivery method (traditional or online), teaching style cluster (containing formal authority style or facilitator style), course type, student’s residence (on-campus, off-campus commuting, or off-campus not commuting), age, and student major on sense of classroom community in terms of emotional connection and learning.

Quantitative research methods were used with a causal-comparative design and survey instruments. Differences were determined …

What Is The Evidence That Increasing The Length Of Breastfeeding Has On Risk Reduction Of Breast Cancer, Jaci K. Phillips

Theses and Dissertations

The focus of this study was to review the literature to determine if breast cancer incidence was reduced by breastfeeding duration. It is important for health care providers to present the benefits of breastfeeding to women of childbearing age and especially to those who are pregnant. This literature review will result in a pamphlet that will be available to health care providers to present to prenatal patients. Informing women about the benefits of breastfeeding and breast cancer risk reduction will promote their ability to make an informed decision on breastfeeding. The Health Belief Model is the framework that was used …

Immunizations And Autism: Educating The Public, Lori L. Slaubaugh

Theses and Dissertations

Research has shown that the avoidance or delay of immunizations can lead to significant outbreaks of diseases previously thought eradicated. Recent outbreaks of diseases, such as measles, have emphasized the need for immunizations to protect each child, which in turn protects the population as a whole. Although research has not substantiated a link between the occurrence of autism and thimerosal , a preservative used in many vaccines since 1930, many parents continue to avoid immunizations out of fear that those containing thimerosal may cause autism in their child. Educating parents on the evidence related to thimerosal as a preservative in …

Handedness As A Predictor Of Success In Far Part 141 Flight Training, Danielle Dracy

Theses and Dissertations

The current study assesses the prevalence of left-, right-, and mixed-handedness and handedness as a predictor of success in flight training. The convenience sample is comprised of students enrolled in or who have previously completed the private pilot course at the University of North Dakota’s Part 141 flight training program. The Edinburgh Handedness Inventory and self-report methods are used to determine subject’s handedness. Success in flight training is assessed using student computerized academic and flight records. Statistical analysis of the data does not show a significant difference between left-, right-, and mixed-handed students with any of the measures used. This …
