Nanotechnology is regarded as one of the key technologies of the future and associated with high expectations by politics, science and economy. Artificially produced nanosized particles and nanoscale system components have new properties which are of importance for the development of new products and applications. Such new properties of materials and substances result from the special properties of surfaces and interfaces and in part, from the geometric shape of the material. In theory nanoparticles (NPs) can be produced from nearly any chemical; however, most NPs that are currently in use today have been made from transition metals, silicon, carbon (single-walled …

Fluorescence Tomography Characterization For Sub-Surface Imaging With Protoporphyrin Ix, Dax Kepshire, Scott C. Davis, Hamid Dehghani, Keith D. Paulsen, Brian W. Pogue

Dartmouth Scholarship

Optical imaging of fluorescent objects embedded in a tissue simulating medium was characterized using non-contact based approaches to fluorescence remittance imaging (FRI) and sub-surface fluorescence diffuse optical tomography (FDOT). Using Protoporphyrin IX as a fluorescent agent, experiments were performed on tissue phantoms comprised of typical in-vivo tumor to normal tissue contrast ratios, ranging from 3.5:1 up to 10:1. It was found that tomographic imaging was able to recover interior inclusions with high contrast relative to the background; however, simple planar fluorescence imaging provided a superior contrast to noise ratio. Overall, FRI performed optimally when the object was located on or …

Clinical Features And Management Of Autoimmune Hepatitis, Edward L. Krawitt Jun 2008

Clinical Features And Management Of Autoimmune Hepatitis, Edward L. Krawitt

Dartmouth Scholarship

Autoimmune hepatitis (AIH) is a chronic hepatitis of unknown etiology which can progress to cirrhosis. Its clinical manifestations are highly variable and sometimes follow a fluctuating course. Diagnosis is based on characteristic histologic, clinical, biochemical and serological findings. Anti-inflammatory/immunosuppressive treatment frequently induces remission but long-term maintenance therapy is often required. Liver transplantation is generally successful in patients with decompensated cirrhosis unresponsive to or intolerant of medical therapy.


The Role Of Extracellular Matrix And Matrix-Degrading Proteases In Neonatal Hypoxic-Ischemic Injury, Christopher C. Leonardo Jun 2008

The Role Of Extracellular Matrix And Matrix-Degrading Proteases In Neonatal Hypoxic-Ischemic Injury, Christopher C. Leonardo

USF Tampa Graduate Theses and Dissertations

Improvements in medical care over recent decades have increased the number of premature and low birth weight infants that survive hypoxic-ischemic (H-I) insults. Because there is a rising incidence in diseases associated with these events, it is critical to develop effective therapies to treat the various resulting neuropathies. Extracellular matrix constitutes the majority of brain parenchyma. Lecticans and matrix-degrading proteases including ADAMTSs (a disintegrin and metalloproteinase with thrombospondin repeats) and matrix metalloproteinases (MMPs) exert effects on cell viability and may be associated with either protective or destructive processes after H-I. Both ADAMTSs (Cross et al. 2006; Tian et al. 2007) …


Structural And Functional Mapping Of The Archaeal Multi-Aminoacyl-Trna Synthetase Complex, Corinne D. Hausmann, Michael Ibba Jun 2008

Structural And Functional Mapping Of The Archaeal Multi-Aminoacyl-Trna Synthetase Complex, Corinne D. Hausmann, Michael Ibba

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Methanothermobacter thermautotrophicus contains a multi-aminoacyl-tRNA synthetase complex (MSC) of LysRS, LeuRS and ProRS. Elongation factor (EF) 1A also associates to the MSC, with LeuRS possibly acting as a core protein. Analysis of the MSC revealed that LysRS and ProRS specifically interact with the idiosyncratic N- and C- termini of LeuRS, respectively. EF-1A instead interacts with the inserted CP1 proofreading domain, consistent with models for post-transfer editing by class I synthetases such as LeuRS. Together with previous genetic data, these findings show that LeuRS plays a central role in mediating interactions within the archaeal MSC by acting as a core scaffolding …

The Development Of Word Recognition Materials For Native Speakers Of Tongan, Lara Cahoon Seaver

Theses and Dissertations

The purpose of this study was to develop, digitally record, evaluate, and psychometrically equate a set of Tongan bisyllabic word lists for use in measurement of word recognition testing. Commonly used bisyllabic words were digitally recorded by male and female native talkers of Tongan. The psychometric performance of the words was measured at ten intensity levels (- 5 to 40 dB HL) in 5 dB increments by 20 listeners with normal hearing acuity. The 200 words with the highest rate of listener identification were included in four relatively psychometrically equivalent word lists of 50 words each and eight half-lists of …


Heart Rate Variability Characteristics In Sedentary Postmenopausal Women Following Six Months Of Exercise Training: The Drew Study, Conrad P. Earnest, Carl J. Lavie, Steven N. Blair, Timothy S. Church Jun 2008

Heart Rate Variability Characteristics In Sedentary Postmenopausal Women Following Six Months Of Exercise Training: The Drew Study, Conrad P. Earnest, Carl J. Lavie, Steven N. Blair, Timothy S. Church

Faculty Publications

Background: Decreased heart rate variability (HRV) is associated with a higher risk of mortality. Overall, postmenopausal women have lower levels of HRV than premenopausal women, which may be additionally complicated by lifestyle related behaviors such as physical inactivity and obesity. Though cardiorespiratory exercise training increases HRV, little is known regarding the exercise dose necessary to promote improvement.

Methodology/Principle Findings: Our primary aim was to measure HRV in post-menopausal women following 6-moths of exercise training. We examined supine resting HRV in 373 post-menopausal women (45-75 y) after 6-months of randomly assigned and double-blinded administered exercise training exercise training at 50%, 100% …

Spatiotemporal Postural Control Deficits Are Present In Those With Chronic Ankle Instability, Patrick O. Mckeon, Jay Hertel Jun 2008

Spatiotemporal Postural Control Deficits Are Present In Those With Chronic Ankle Instability, Patrick O. Mckeon, Jay Hertel

Physical Therapy Faculty Publications

BACKGROUND: Postural control deficits have been purported to be a potential contributing factor in chronic ankle instability (CAI). Summary forceplate measures such as center of pressure velocity and area have not consistently detected postural control deficits associated with CAI. A novel measurement technique derived from the dynamical systems theory of motor control known as Time-to-boundary (TTB) has shown promise in detecting deficits in postural control related to chronic ankle instability (CAI). In a previous study, TTB deficits were detected in a sample of females with CAI. The purpose of this study was to examine postural control in sample of males …


Enhancing Autonomy In Paid Surrogacy, Jennifer Damelio '06, Kelly Sorensen Jun 2008

Enhancing Autonomy In Paid Surrogacy, Jennifer Damelio '06, Kelly Sorensen

Philosophy and Religious Studies Faculty Publications

The gestational surrogate – and her economic and educational vulnerability in particular – is the focus of many of the most persistent worries about paid surrogacy. Those who employ her, and those who broker and organize her services, usually have an advantage over her in resources and information. That asymmetry exposes her to the possibility of exploitation and abuse. Accordingly, some argue for banning paid surrogacy. Others defend legal permission on grounds of surrogate autonomy, but often retain concerns about the surrogate. In response to the dilemma of a ban versus bald permission, we propose a ‘soft law’ approach: states …


Subcutaneous Late Phase Responses Are Augmented During Local Inhalational Tolerance In A Murine Asthma Model, Anurag Singh, Roger S. Thrall, Linda A. Guernsey, William F. Carson Iv, Eric R. Secor Jr, Robert E. Cone, Thiruchandurai V. Rajan, Craig M. Schramm Jun 2008

Subcutaneous Late Phase Responses Are Augmented During Local Inhalational Tolerance In A Murine Asthma Model, Anurag Singh, Roger S. Thrall, Linda A. Guernsey, William F. Carson Iv, Eric R. Secor Jr, Robert E. Cone, Thiruchandurai V. Rajan, Craig M. Schramm

UCHC Articles - Research

Acute exposure of sensitized mice to antigen elicits allergic airway disease (AAD) characterized by Th2 cytokine-dependent pulmonary eosinophilia, methacholine hyperresponsiveness and antigen-specific IgE elevation. However, chronic exposure induces a local inhalational tolerance (LIT), with resolution of the airway responses but persistent systemic IgE production. To further determine if systemic immunologic responses were maintained during LIT, we assessed subcutaneous late phase responses to ovalbumin in this model. Sensitized and AAD mice developed small subcutaneous responses to ovalbumin, with footpad thickness increasing to 113.7 and 113.6% of baseline, respectively. In comparison, LIT mice developed marked foot swelling (141.6%). Histologic examination confirmed increased …

Separation And Characterization Of Respirable Amphibole Fibers From Libby, Montana, James S. Webber, David J. Blake, Tony Ward, Jean C. Pfau

Public and Community Health Sciences Faculty Publications

The vermiculite mine in Libby, Montana, was in operation for over 70 yr and was contaminated with asbestos-like amphibole fibers. The mining, processing, and shipping of this vermiculite led to significant fiber inhalation exposure throughout the community, and residents of Libby have developed numerous pulmonary diseases such as lung cancer and mesothelioma. The present study describes the separation of Libby 6-mix into respirable and nonrespirable size fractions by means of aqueous elutriation. The elutriator, designed to separate fibers with aerodynamic diameters smaller than 2.5 μm (respirable) from larger fibers, used an upward flow rate of 3.4 × 10−4 …

The Evolution Of Language And Perception Of Disability In Occupational Therapy, Kathryn M. Loukas Jun 2008

The Evolution Of Language And Perception Of Disability In Occupational Therapy, Kathryn M. Loukas

Occupational Therapy Faculty Publications

How do occupational therapy practitioners refer to the persons they serve, and how do these terms reflect our perception of disability as a profession? In the hospital or medical model, we call these persons patients; in the community we referred to them as clients; in the marketplace, they may be called consumers. Children serviced through the schools often are called students, and persons in long-term care may be called residents. However, most of the individuals we serve carry a diagnostic label that makes them eligible for services and defines the work of therapy (Centers for Disease Control and Prevention [CDC], …


Effects Of Acute Ethyl Alcohol Consumption On A Psychophysical Measure Of Lateral Inhibition In Human Vision., Kevin D Johnston, Brian Timney Jun 2008

Effects Of Acute Ethyl Alcohol Consumption On A Psychophysical Measure Of Lateral Inhibition In Human Vision., Kevin D Johnston, Brian Timney

Brain and Mind Institute Researchers' Publications

Acute consumption of ethyl alcohol affects a variety of visual functions. However, there have been few systematic attempts to investigate the neural mechanisms underlying these effects. Here, we employed the Westheimer paradigm to investigate the hypothesis that alcohol reduces lateral inhibition within human "perceptive fields", the psychophysical analogue of physiological receptive fields. Westheimer functions obtained under alcohol and no-alcohol conditions at photopic, mesopic, and scotopic levels of adaptation showed changes consistent with an alcohol-induced decrease in lateral inhibition. We conclude that this decrease in lateral inhibition may be responsible for some of the changes in visual perception that result from …

Relative Timing Of Speech Motor Events At Utterance Invitation In Persons Who Do And Do Not Stutter, Bryan Thomas Brown Jun 2008

Relative Timing Of Speech Motor Events At Utterance Invitation In Persons Who Do And Do Not Stutter, Bryan Thomas Brown

Masters Theses

Speech production is a highly complex speech motor activity that presumably requires a high degree of coordination between articulatory, respiratory and phonatory subsystems. Stuttering may be caused by breakdowns in speech motor coordination. The current study attempted to evaluate timing relationship between these systems at speech initiation in the perceptually fluent speech of people who do and do not stutter. To study this, tongue blade speed histories, respiratory transitions from inspiratory to expiratory gestures, and acoustic events at the initiation of perceptually fluent speech in persons who stutter and normally fluent speakers were analyzed in relative time. To identify the …

Essential Novice Nurse Educator Role Competencies And Qualifications To Teach Ina Pre-Licensure Registered Nurse Education Program, Kathleen A. Poindexter

Dissertations

Expert nurse clinicians who are transitioning into academic positions after successful clinical careers often find they are unprepared to assume their new educator roles. While nursing clinical expertise may be a necessary expectation, the knowledge is not sufficient to assume a nurse educator position. Novice nurse educators prepared with the essential qualifications and competencies associated with the specialty role of a nurse educator will be better able to transition into their new academic roles. This study identified essential entry-level nurse educators' competencies and qualifications as reported by nursing administrators of accredited pre-licensure nursing programs across the United States.

Department of Cancer Biology Faculty Papers

The PC12 pheochromocytoma cell line responds to nerve growth factor (NGF) by exiting from the cell cycle and differentiating to induce extending neurites. Cyclin D1 is an important regulator of G1/S phase cell cycle progression, and it is known to play a role in myocyte differentiation in cultured cells. Herein, NGF induced cyclin D1 promoter, mRNA, and protein expression via the p21(RAS) pathway. Antisense- or small interfering RNA to cyclin D1 abolished NGF-mediated neurite outgrowth, demonstrating the essential role of cyclin D1 in NGF-mediated differentiation. Expression vectors encoding mutants of the Ras/mitogen-activated protein kinase pathway, and chemical inhibitors, demonstrated NGF …
