Regulation Of Radioactive Fracking Waste, Elizabeth Ann Glass Geltman, Nichole Leclair

Publications and Research

Natural gas extracted form shale reached record production totals in 2015 in the United States and the US Energy Information Administration (EIA) forecasts natural gas production will continue to increase. Wastes from shale gas extraction can contain the radioactive isotopes radium-226 (Ra-226) and radium-228 (Ra-228), which decay further into radon (Rn). Exposure to radon, a form of naturally occurring radioactive materials (NORM), is the leading cause of lung cancer in the United States, after smoking. This article explores how states handle the disposal of technologically enhanced naturally occurring radioactive materials (TENORM) and/or NORM waste from oil and gas operations to …

Faculty & Staff Scholarship

Most Veterans who use the Veterans Health Administration (VHA) also utilize private-sector health care providers. To better inform local and regional health care planning, we assessed the association between reliance on VHA ambulatory care and total and system-specific preventable hospitalization rates (PHRs) at the state level. We conducted a retrospective dynamic cohort study using Veterans with diabetes mellitus, aged 66 years or older, and dually enrolled in VHA and Medicare parts A and B from 2004 to 2010. While controlling for median age and proportion of males, we measured the association between reliance on VHA ambulatory care and PHRs at …

Photoluminescence Mechanism And Applications Of Zn-Doped Carbon Dots, Quan Xu, Wei Cai, Miaoran Zhang, Yingchun Ye, Yeqing Li, Lipeng Zhang, Yongjian Guo, Zhiqiang Yu, Siyu Li, Xun Lin, Yusheng Chen, Yan Lou, Jason Street, Meng Xu

Faculty & Staff Scholarship

Heteroatom-doped carbon dots (CDs) with excellent optical characteristics and negligible toxicity have emerged in many applications including bioimaging, biosensing, photocatalysis, and photothermal therapy. The metal-doping of CDs using various heteroatoms results in an enhancement of the photophysics but also imparts them with multifunctionality. However, unlike nonmetal doping, typical metal doping results in low fluorescence quantum yields (QYs), and an unclear photoluminescence mechanism. In this contribution, we detail results concerning zinc doped CDs (Zn-CDs) with QYs of up to 35%. The zinc ion charges serve as a surface passivating agent and prevent the aggregation of graphene p–p stacking, leading to an …

Accumulation of senescent cells over time contributes to aging and age-related diseases. However, what drives senescence in vivo is not clear. Here we used a genetic approach to determine if spontaneous nuclear DNA damage is sufficient to initiate senescence in mammals. Ercc1-/Δ mice with reduced expression of ERCC1-XPF endonuclease have impaired capacity to repair the nuclear genome. Ercc1-/Δ mice accumulated spontaneous, oxidative DNA damage more rapidly than wild-type (WT) mice. As a consequence, senescent cells accumulated more rapidly in Ercc1-/Δ mice compared to repair-competent animals. However, the levels of DNA damage and senescent cells in Ercc1-/Δ mice never exceeded that …

Recent Advances In A Three-Dimensional Fabrication Of Hydroxyapatite-Based Biomaterials For Craniofacial Bone Regeneration, Chanekrid Oupadissakoon, Weerachai Singhatanadgit

Chulalongkorn University Dental Journal

Surgical treatment of craniofacial bone abnormalities, caused by head and neck cancers, bone fractures, congenital deformities and periodontal diseases, involves the reconstruction using bone graft implantation. Due to limitations and complications from the use of autogenic and allogenic bone grafts, synthetic bonelike ceramics have therefore become widely used, particularly for hydroxyapatite (HA), which has been used for a multitude of medical applications. Because of an advanced technology in the field of stem cell research and tissue engineering, highly sophisticated and functionalized tissues can be constructed using 3-dimensional (3D) fabricating technology in order to replace the use of human structures or …

The Effectiveness Of Oral Non-Steroidal Anti-Inflammatories Versus Steroid Injections In Patients With Shoulder Pain, Darren Scott Pledger

Physician Assistant Scholarly Project Papers

Shoulder pain is the third most common musculoskeletal complaint in primary care. Therefore, it is important that we have quality evidenced based treatments to guide clinicians in treating shoulder pain. I examined in this review whether corticosteroid injection into the glenohumeral joint or oral NSAIDs was more effective in reducing shoulder pain as well as the side effects associated with each treatment modality. Search methods included the PubMed and Cochrane databases. Only studies comparing corticosteroid injection and oral NSAIDs were included and not each treatment individually. In conclusion, corticosteroid injections into the glenohumeral joint accelerate pain relief but have equal …

Persistent Stress-Induced Neuroplastic Changes In The Locus Coeruleus/Norepinephrine System, Olga Borodovitsyna, Neal Joshi, Daniel Chandler

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Neural plasticity plays a critical role in mediating short- and long-term brain responses to environmental stimuli. A major effector of plasticity throughout many regions of the brain is stress. Activation of the locus coeruleus (LC) is a critical step in mediating the neuroendocrine and behavioral limbs of the stress response. During stressor exposure, activation of the hypothalamic-pituitary-adrenal axis promotes release of corticotropin-releasing factor in LC, where its signaling promotes a number of physiological and cellular changes. While the acute effects of stress on LC physiology have been described, its long-term effects are less clear. This review will describe how stress …

Childhood Trauma: An Analysis Of Associated Co-Morbidities And Various Psychotherapies, Brittney L. Benson

Physician Assistant Scholarly Project Posters

American and European studies suggest that anywhere from 14 to 67% of children have experienced at least one traumatic event throughout their life. Furthermore, about 13.4% of them go on to develop post-traumatic stress disorder (PTSD) or symptoms (Diehle, J., Opmeer, B.C., Boer, F., Mannarino, A.P., & Lindauer, R.J., 2015). One study suggests that as many as 63.9% of adults suffer from ACEs (Adverse Childhood Experiences) (CDC, 2016). The 4th Edition of the Diagnostic and Statistical Manual (DSM-IV) states that PTSD is the most common Axis I disorder in children that are victims of abuse with statistics ranging from 20% …

Pre-Participation Physical Exams: Are We Doing Enough?, Steven Jacob Pietrusza

Physician Assistant Scholarly Project Posters

•Inclusion of screening electrocardiograms (EKGs) during pre-participation physical examination has been a topic of debate for some time. There is unquestioned usefulness in the ability of a well-trained health care provider in using EKG to identify cardiac abnormalities.

•Further, there have been several contemporary EKG criteria published that increase specificity and sensitivity of detection of disease. However, these criteria do not account for athletes less than 14 years of age, and that demographic represents a large portion of patients seeking pre-participation screenings in the United States.

•The lack of research into pediatric cardiac remodeling secondary to activity, coupled with the …

New Ways Of Predicting Efficacy Of Antidepressants, Kayla Ternes

Physician Assistant Scholarly Project Posters

Major depressive disorder (MDD) is a neuropsychiatric condition that is becoming increasingly prevalent in our country. According to Cai, Huang, and Hao (2015), MDD is “common and devastating” (p. 61) and has a very complex pathophysiology. Until recently, a definitive etiology had not been found, however, new evidence has suggested that Brain-derived neurotrophic factor (BDNF) and cognitive-emotional biomarkers may be a key into the mechanism of this disorder.

A literature review of articles found in PubMed, CINAHL, Cochrane Library, and PsychINFO within the last ten years focused on the hypotheses of the pathophysiology of MDD, cognitive-emotional biomarkers, and BDNF. The …

Antibiotic Therapy In Preventing Exacerbations Of Severe Chronic Obstructive Pulmonary Disease, Jamie Trautner

Physician Assistant Scholarly Project Posters

• Chronic obstructive pulmonary disease (COPD) is a progressive disease that has no cure but is treatable. The treatment goal is to have adequate symptom control, decreased exacerbations, prevent hospitalizations and maintain an independent quality of life.

• The review of literature is to determine if the benefits of long-term antimicrobial therapy outweigh the risks in the treatment of severe COPD.

• The gold standard for pharmacotherapy consists of inhaled corticosteroids and bronchodilators (long-acting beta2agonist (LABA).

• Adding azithromycin to standard therapy for patients with frequent exacerbations showed a 27% reduction in exacerbation frequency.

• With prolonged use of antimicrobials …

Development Of Low Frequency Electron Paramagnetic Resonance Methods And Instrumentation For Biological Applications, Laura A. Buchanan

Electronic Theses and Dissertations

EPR is a powerful biophysical tool that can be used to measure tumor physiology. With the addition of magnetic field gradients, the spectral properties of paramagnetic species can be mapped. To facilitate EPR imaging, methods and instrumentation at frequencies between 250 MHz and 1 GHz were developed.

At low spin concentrations, the rapid scan background signal is often many times larger than the EPR signal of interest. To help remove the background contribution, a data acquisition procedure that takes advantage of a cross-loop resonator and bipolar power supplies was developed at 250 MHz. In this procedure, two scans are collected. …

The current study is the first to explore treatment outcomes of session-limited models (measured by Therapist Perception of Change, TPC) for diagnoses (anxiety and depression) in an EAP delivery system. Outcomes were measured by TPC ratings including: a) Regressed, b) remained at Baseline, c) Improved, and d) issue was Resolved. Analyses (Chi-Square and =t-test) were used …

Studying Facial Expression Recognition And Imitation Ability Of Children With Autism Spectrum Disorder In Interaction With A Social Robot, Farzaneh Askari

Electronic Theses and Dissertations

Children with Autism Spectrum Disorder (ASD) experience limited abilities in recognizing non-verbal elements of social interactions such as facial expressions [1]. They also show deficiencies in imitating facial expressions in social situations. In this Master thesis, we focus on studying the ability of children with ASD in recognizing facial expressions and imitating the expressions using a rear-projected expressive humanoid robot, called Ryan. Recent studies show that social robots such as Ryan have great potential for autism therapy. We designed and developed three studies, first to evaluate the ability of children with ASD in recognizing facial expressions that are presented to …
