Female Veterans' Combat Experience And Ptsd On Male Partners' Psychological Distress And Relationship Quality, Theresa Denise Abraham

Walden Dissertations and Doctoral Studies

Female veterans' combat exposure to trauma places them at risk for developing posttraumatic stress disorder (PTSD), which has consequences for healthful reintegration to family and civilian life. Previous research found that wives who provide continuous care to male veterans with PTSD experience symptoms of psychological distress; however, little research has been conducted on the influence of female veterans' PTSD on their intimate male partners' (IMPs) psychological well-being. A multivariate correlational design was used to examine the influence of female veteran PTSD on psychological distress and relationship quality in IMPs. The couples' adaption to traumatic stress model was used as the …

Rapid Prototyping Of Mixing Elements In Bioreactor System, Angela Clyde, Chris Cooper, Aaron Dryden, Erik Olson, Jaden Markos, Ryan Randall, Spencer Lynch, Mark Smith

Emerging technologies, such as 3D printing, have revolutionized the way in which engineers prototype innovative designs. Here, students optimized a procedure for rapidly prototyping mixing elements in a Thermo Fisher Scientific bioreactor, using 3D printing. Impellers were designed using AutoCAD and SolidWorks drafting software, 3D printed on a Fortus 3D printer, and evaluated via application specific bioreactor simulations.

Three different bioreactor applications were modeled – high density cell culture, solid dissolution, and microcarrier cell culture – each with their own impeller designs and testing procedures.

Project Objectives:

• Develop an iterative process for rapid prototyping bioreactor impellers.

• Design and …

3 Day Emergency Dialysis Kit, Luke Fillingim, Aaron Marshall, Brandi Thielman

Biological Engineering

Following natural disasters, dialysis clinics are unable to provide treatment for their patients. Many city facilities and vital services, such as water and power, can remain damaged or unavailable for as many as a few weeks

In one instance, it was reported that after a natural disaster the five leading causes of dialysis clinics becoming inoperable were: damage to reverse osmosis systems, interruption of water supply, failure of electrical power supply, structural damage to buildings and failure of telecommunications³.

Unfortunately, patients with end stage renal disease have the potential to become very sick in a matter of days …

An Assessment Of The Potential Impacts Of Climate Change On The Freshwater Habitats Of Indiana, U.S.A., Tomas Höök, Carolyn Foley, Paris Collingsworth, Leslie Dorworth, Brant Fisher, Jason Hoverman Dr., Elizabeth Larue, Mark Pryon, J. L. Tank

Aquatic Ecosystems Publications

Recent climate-driven, physico-chemical changes documented in aquatic systems throughout the world are expected to intensify in the future. Specifically, changes in key environmental attributes of aquatic systems, such as water quantity, clarity, temperatures, ice cover, seasonal flow regimes, external loading, and oxygen content, will undoubtedly have a broad set of direct and indirect ecological consequences. Some anticipated impacts may be similar across different aquatic ecosystems, while others may be system-specific. Here, we review the potential effects of climatic changes for different freshwater habitats within the state of Indiana, USA, a Midwestern state with diverse land and water features. Given this …

Suku Bangsa Enggano Dalam Perdebatan Rumpun Bangsa Dan Bahasa Austronesia: Suatu Tinjauan Antropologis, Iman Fachruliansyah

Antropologi Indonesia

Enggano Island is located at the southernmost of the Barrier Islands, after Simeulue, Nias and Mentawai, off Sumatra’s west coast. Rising up from the deep seabed of the Indian Ocean, Enggano is often described as an isolated island. Literature on the inhabitants, known as the Engganese, are scarce or else limited to travel account and stories about their traditional culture that are no longer practiced. Studies on Enggano, especially in anthropology, archaeology, and linguistics, attempted to group Engganese language and culture with Nias and Mentawai given the close geographical location and degree of similarities. The Engganese position within the Austronesian …

Ecological Benefits Of Watershed-Scale Restoration In Two Intensively Mined Cold- And Warm-Water Ecosystems, Rebecca Anne Long

Graduate Theses, Dissertations, and Problem Reports (ETD)

Stream restoration projects are increasingly common. However, restoration projects that establish measurable goals, have pre- and post-restoration monitoring, and are implemented at the watershed scale are rare. We conducted a long-term (9-year) before-after-control-impact designed assessment of two watershed-scale acid mine drainage (AMD) remediation programs, one in a warm-water ecosystem and one in a cold-water ecosystem in West Virginia, USA. Restoration was strategically designed to recover biodiversity and improve the native fisheries by restoring chemically degraded water quality and re-establishing riverscape connectivity. We used analysis of variance to quantify responses in water chemistry, benthic macroinvertebrate communities, and fish community composition before …

In Vitro Metabolism Of The Synthetic Cannabinoids Px-1, Px-2, Px-3 And A Comparison Of Their Clearance Rates In Human Liver Microsomes, Travon Cooman

Graduate Theses, Dissertations, and Problem Reports (ETD)

Detection of SCs in body fluids continue to be a challenge because of limited metabolism data, lack of standards and reference mass spectrometry data. In vivo and in vitro experiments help elucidate metabolite markers for novel psychoactive substances and can prompt synthesis of standards to verify proposed metabolites. In this study, metabolism of three SCs N-(1-amino-1-oxo-3-phenylpropan-2-yl)-1-(5-fluoropentyl)-1H-indole-3-carboxamine (PX-1), N-(1-amino-1-oxo-3-phenylpropan-2-yl)-1-(5-fluropentyl)-1H-indazole-3-carboxamide (PX-2), and N-(1-amino-1-oxo-3-phenylpropan-2-yl)-1-(cyclohexylmethyl)-1H-indazole-3-carboxamide (PX-3) were investigated using human liver microsomes. Previous studies showed PX-3 as the most potent CB1 and CB2 receptor agonist.

Half-life and clearance data were acquired using liquid chromatography- tandem mass spectrometry. Metabolite elucidation was performed using liquid chromatography …

Stream Salamander And Benthic Macroinvertebrate Community Responses To Imidacloprid Exposure, Sara M. Crayton

Graduate Theses, Dissertations, and Problem Reports (ETD)

The insecticide imidacloprid is widely used to mitigate hemlock (Tsuga spp.) mortality resulting from the invasive hemlock woolly adelgid (HWA), but evidence suggests that

imidacloprid can have negative effects on adjacent stream systems. Imidacloprid exposure causes physiological changes, bioaccumulation, and reduced survival in anurans, and induces physiological impairment and reduced survival in benthic macroinvertebrates. In this thesis, we assessed whether HWA treatments using imidacloprid affect stream salamander abundances and benthic macroinvertebrate community composition. We also investigated whether imidacloprid or its metabolites bioaccumulate in benthic macroinvertebrates or salamanders and cause sublethal effects. We conducted this study in two National Park …

Investigating The Role Of Coyotes, Canis Latrans, In The Spread Of Parasites And Arthropod-Borne Diseases In Georgia, Usa., Ansleigh Banks

College of Graduate Studies: Theses & Dissertations

In order to analyze the role of coyotes, Canis latrans, as hosts of parasites and arthropod-borne diseases in the state of Georgia, USA, 38 coyotes representing 18 counties and multiple geographic regions of the state were dissected and analyzed for the presence of Dirofilaria immitis, intestinal parasites, ectoparasites, and tick-borne illnesses. Mosquitoes from the locations which the coyotes originated were trapped and analyzed for the presence of D. immitis larvae. In compliance with IACUC guidelines, coyotes were obtained from individuals who had previously hunted or trapped the coyotes for leisure. Parasites were identified based on morphological features with the use …

Waste Management Of Highway Right Of Way Areas In Southeast Georgia, David M. Penn Ii

College of Graduate Studies: Theses & Dissertations

Maintenance of highway right of way (ROW) areas has become problematic during the last several years due to the high cost, and little to no economic return associated with disposing vegetation waste that is continuously generated on all highways and interstates across the state of Georgia. The Georgia Department of Transportation (GDOT) was interested in evaluating the feasibility of replacing ROW vegetation of highways throughout the state with high-value alternatives such as switchgrass (Panicum virgatum L. ‘Alamo’), big bluestem (Andropogon gerardii) and woodland sunflower (Helianthus divaricatus). Preliminary objective involved measuring and mapping SOC and soil N concentrations in the highway …

Circulating Tumour Dna (Ctdna) As A Biomarker In Metachronous Melanoma And Colorectal Cancer- A Case Report, Leslie Calapre, Lydia Warburton, Michael Millward, Elin S. Gray

Research outputs 2014 to 2021

Background: Circulating tumour DNA (ctDNA) has emerged as a promising blood-based biomarker for monitoring disease status of patients with advanced cancers. The presence of ctDNA in the blood is a result of biological processes, namely tumour cell apoptosis and/or necrosis, and can be used to monitor different cancers by targeting cancer-specific mutation. Case presentation: We present the case of a 67 year old Caucasian male that was initially treated with BRAF inhibitors followed by anti-CTLA4 and then anti-PD1 immunotherapy for metastatic melanoma but later developed colorectal cancer. The kinetics of ctDNA derived from each cancer type were monitored targeting BRAF …

Genomic Prediction Of Relapse In Recipients Of Allogeneic Haematopoietic Stem Cell Transplantation., J Ritari, K Hyvärinen, S Koskela, M Itälä-Remes, R Niittyvuopio, A Nihtinen, U Salmenniemi, M Putkonen, L Volin, T Kwan, T Pastinen, J Partanen

Manuscripts, Articles, Book Chapters and Other Papers

Allogeneic haematopoietic stem cell transplantation currently represents the primary potentially curative treatment for cancers of the blood and bone marrow. While relapse occurs in approximately 30% of patients, few risk-modifying genetic variants have been identified. The present study evaluates the predictive potential of patient genetics on relapse risk in a genome-wide manner. We studied 151 graft recipients with HLA-matched sibling donors by sequencing the whole-exome, active immunoregulatory regions, and the full MHC region. To assess the predictive capability and contributions of SNPs and INDELs, we employed machine learning and a feature selection approach in a cross-validation framework to discover the …

Risks And Remedies For Artificial Intelligence In Healthcare, W. Nicholson Price Ii

Other Publications

Artificial intelligence (AI) is rapidly entering health care and serving major roles, from automating drudgery and routine tasks in medical practice to managing patients and medical resources. As developers create AI systems to take on these tasks, several risks and challenges emerge, including the risk of injuries to patients from AI system errors, the risk to patient privacy of data acquisition and AI inference, and more. Potential solutions are complex but involve investment in infrastructure for high-quality, representative data; collaborative oversight by both the Food and Drug Administration and other health-care actors; and changes to medical education that will prepare …

Characterization Of Polyphenols In Australian Sweet Lupin (Lupinus Angustifolius) Seed Coat By Hplc-Dad-Esi-Ms/Ms, Liezhou Zhong, Gangcheng Wu, Zhongxiang Fang, Mark L. Wahlqvist, Jonathan M. Hodgson, Michael W. Clarke, Edwin Junaldi, Stuart K. Johnson

Research outputs 2014 to 2021

Seeds of the legume lupin (Lupinus spp.) are becoming increasingly important as human food. The seed coat, at ~25% of the whole seed of Lupinus angustifolius (Australian sweet lupin, ASL), is the main by-product of lupin kernel flour production. The primary market for lupin seed coat is low value feed with very limited use in foods. In this study, seed coats of six ASL commercial varieties from two growing sites were sampled for identification and quantification of polyphenols using a high-performance liquid chromatography (HPLC) with diode array detector (DAD) and coupled with a triple quadrupole mass spectrometer which equipped with …

Cationic Biaryl 1,2,3-Triazolyl Peptidomimetic Amphiphiles: Synthesis, Antibacterial Evaluation And Preliminary Mechanism Of Action Studies, Andrew J. Tague, Papanin Putsathit, Katherine A. Hammer, Steven M. Wales, Daniel R. Knight, Thomas V. Riley, Paul A. Keller, Stephen G. Pyne

Research outputs 2014 to 2021

Synthetic small molecular antimicrobial peptidomimetics represent a promising new class of potential antibiotics due to their membrane-disrupting ability and their decreased propensity for bacterial resistance. A library of 43 mono- and di-cationic biaryl 1,2,3-triazolyl peptidomimetics was designed and synthesized based upon previously established lead biarylpeptidomimetics and a known pharmacophore. A reliable, facile and modular synthetic pathway allowed for the efficient synthesis of multiple unique scaffolds which were subjected to divergent derivatization to furnish the amphiphilic compounds. In vitro testing revealed enhanced antibacterial efficacy against a range of pathogenic bacteria, including bacterial isolates with methicillin, vancomycin, daptomycin, or multi-drug resistance. Preliminary …

A Comparative Study On Genetic Profiles And Repellent Effects Of Murraya Koenigii From Four Regions In Kenya On Anopheles Gambiae S.S., Sean Waswa Levi

All Master’s Theses

Ethnobotanical analyses highlight therapeutic and chemotypic variations of geographically and ecologically diverse Murraya koenigii (Spreng) samples. However, the genetic correlation of this observation remains obscure. The present study aimed at studying the intraspecific genetic variation of Murraya koenigii and the possible effect on the bioactivity of volatiles of plant samples collected from four different geographical locations of Kenya. Genomic DNA isolated from various plant samples were screened for plastid maturase K (matK) gene polymorphisms within and among populations to estimate genetic diversity and phylogenetic relationships. Further, oils from the plant samples were tested for repellent activity against Anopheles gambiae s.s …

Widening Gyre: A Poetics Of Ocean Plastics, Mandy Bloomfield

School of Law, Humanities and Social Sciences

By focusing on contemporary experimental poetry that engages with ocean plastics, this essay explores the capacity of ecopoetics to make distinctive interventions in the environmental humanities, and in particular the blue humanities. It examines work by Stephen Collis, Adam Dickinson, and Evelyn Reilly to show how poetry’s forms of juxtaposition, linkage, linguistic porosity, indeterminacy, and nonnarrative temporalities suggest fertile modes of cultural engagement with the more-than-human oceans. This poetry cultivates amplified modes of attention to more-than-human scales of space, time, agency, and modes of relation, and it performs highly material ways of understanding historical, economic, and aesthetic forces affecting the …

Race, Racism, And American Law': A Seminar From The Indigenous, Black, And Immigrant Legal Perspectives, Monte Mills, Eduardo R.C. Capulong, Andrew King-Ries

Articles

Flagrant racism has characterized the Trump era from the onset. Beginning with the 2016 presidential campaign, Trump has inflamed long-festering racial wounds and unleashed white supremacist reaction to the nation’s first black President, in the process destabilizing our sense of the nation’s racial progress and upending core principles of legality, equality, and justice. As law professors, we sought to rise to these challenges and prepare the next generation of lawyers to succeed in a different and more polarized future. Our shared commitment resulted in a new course, “Race, Racism, and American Law,” in which we sought to explore the roots …

Attacking Innovation, Xuan-Thao Nguyen, Jeffrey A. Maine

Articles

Economists generally agree that innovation is important to economic growth and that government support for innovation is necessary. Historically, the U.S. government has supported innovation in a variety of ways: (1) a strong legal system for patents; (2) direct support through research performed by government agencies, grants, loans, and loan guarantees; and (3) indirect support through various tax incentives for private firms. In recent years, however, we have seen a weakening of the U.S. patent system, a decline in direct funding of research, and a weakening of tax policy tools used to encourage new innovation. These disruptive changes threaten the …

The Surprising Reach Of Fda Regulation Of Cannabis Even After Rescheduling, Sean M. O'Connor, Erika Lietzan

Articles

As more states legalize cannabis, the push to “deschedule” it from the Controlled Substances Act is gaining momentum. At the same time, the Food and Drug Administration (FDA) recently approved the first conventional drug containing a cannabinoid derived from cannabis—cannabidiol (CBD) for two rare seizure disorders. This would all seem to bode well for proponents of full federal legalization of medical cannabis. But some traditional providers are wary of drug companies pulling medical cannabis into the regular small molecule drug development system. The FDA’s focus on precise analytical characterization and on individual active and inactive ingredients may be fundamentally inconsistent …

Effects Of Aquatic Acidification On Calcium Uptake In White River Shrimp Litopenaeus Setiferus Gills, Maria-Flora Jacobs

UNF Graduate Theses and Dissertations

Previous research regarding aquatic acidification has examined the protonation of the carbonate and does not consider calcium to be a limiting factor. This is the first study to suggest that pH may affect the uptake of calcium in crustacean gills. This project describes ion transport mechanisms present in the cell membranes of white river shrimp Litopenaeus setiferus gill epithelium, and the effects of pH on the uptake of calcium by these means. Partially purified membrane vesicles (PPMV) of shrimp gills were prepared through a homogenization process that has been used previously to define ion transport in crab and lobster gill …
