Near-Field Electrospinning And Characterization Of Biodegradable Small Diameter Vascular Grafts, William E. King Iii

Theses and Dissertations (ETD)

The ideal “off the shelf” tissue engineering, small-diameter (< 6 mm inner diameter (ID)) vascular graft hinges on designing a template that facilitates transmural ingrowth of capillaries to regenerate an endothelized neointimal surface. Previous traditionally electrospun (TES) approaches to create bioresorbable vascular grafts lack the pore sizes required to facilitate transmural capillary ingrowth required for successful in situ neovascular regeneration. Therefore, the ability to create scaffolds with program-specific architectures independent of fiber diameter via the relatively recent sub-technique of near-field electrospinning (NFES) represents a promising solution to create tissue engineering vascular grafts. These programmed large pore sizes are anticipated to promote in situ regeneration and improve the outcomes as well as the quality of life of patients with arterial disease.

In this dissertation, we manufactured via NFES as well as characterized biodegradable polydioxanone (PDO) small-diameter vascular grafts. Chapter 1 introduces the need for off-the-shelf, small-diameter vascular grafts to facilitate in situ regeneration, the process and pore size limitations of TES vascular grafts, and the promising use of NFES to develop precisely tailored PDO vascular grafts. Chapter 2 describes the process of NFES and details the current progress in NFES of biomedical polymers as well as the major limitations that exist in the field. Chapters 3, 4, and 5 contain primary research …

Reiki For Recovery: Incorporating Japanese Health Practices To Increase Contemporary Resiliency In American Health, Leif Peterson

Master's Projects and Capstones

The Japanese health practice of Reiki attempts to maximize the latent ability of the human system to heal itself. The Reiki system, established over a century ago, combines multiple Asian health traditions, experimenting with practices that maximize the natural processes of the body to perform its own repairs. Reiki encourages healthy behaviors that balance the mind and body, return the human system to a lowered stress level, and allow for an optimal recovery state for the patient. This paper illustrates how this Japanese health-affirming method can be integrated and utilized within existing health and medical practices. An area that is …

The Role Of Fractionated Exhaled Nitric Oxide (Feno) In Eosinophilic Esophagitis And The Relationship With Downstream Eosinophils, Panamdeep Kaur

Research Days

Background: Eosinophilic Esophagitis (EoE) is a chronic immune mediated disease of the esophagus characterized by symptoms of esophageal dysfunction and eosinophilic-predominant inflammation of the esophagus. It can lead to feeding difficulties, failure to thrive, and esophageal stricturing. Currently, the gold standard for diagnosis and assessing response to therapy is upper endoscopy and histopathological analysis of biopsies. A noninvasive, cost-effective, and low risk alternative that can aid in the management of EoE is not currently available. Previous studies assessing correlation of fractionated exhaled nitric oxide (FeNO) with degree of esophageal eosinophilic inflammation were low powered but noted a trend for association. …

Posterior Reversible Encephalopathy Syndrome (Pres), Brittany Fera, Andrew Caravello

Rowan-Virtua Research Day

Posterior reversible encephalopathy syndrome (PRES) is a clinical and radiographic syndrome that describes certain neuroimaging findings in association with clinical symptoms such as headache, seizure, encephalopathy and vision changes. Classically, PRES is associated with poorly controlled hypertension, and patients present with elevated blood pressure in addition to their symptoms. Most importantly, imaging findings and symptoms are typically reversible, and are a separate entity from ischemic or hemorrhagic cerebrovascular accidents or autoimmune causes of similar symptoms, such as multiple sclerosis.

Novel Technology Enables Diagnostic Ultrasound Machine To Treat Hepatocellular Carcinoma In Mice, Ryan Morrison, Mrigendra B. Karmacharya, Chandra M. Sehgal

Rowan-Virtua Research Day

An off-the-shelf diagnostic transducer (ULTRASONIX C5-2) was modified with custom-built circuitry to enable the transducer to produce therapeutic ultrasound in order to ablate hepatocellular carcinomas grown in immunodeficient athymic nude mice (25-35 g; Charles River Laboratories, Wilmington, MA, USA). The therapeutic antivascular ultrasound (AVUS) produced by the off-the-shelf abdominal transducer was unfocused, continuous 2.8MHz ultrasound targeting contrast-enhancing perflutren lipid microbubbles within tumor vasculature. Previous research with a dedicated physiotherapy ultrasound machine (D150 Plus, Dynatronics Corp., Salt Lake City, UT, USA) targeting similar hepatocellular carcinomas showed disrupted tumor neovasculature and irreparable dilation of tumor capillaries with subsequent intercellular edema and hemorrhage.1-3 …

Osteopathic Touch: The Best Diagnostic & Therapeutic Tool - Osteopathic Diagnosis & Treatment For Nephrolithiasis, Bilal Khan, Motasem Abul-Huda, Alexander King

Rowan-Virtua Research Day

Osteopathic Manipulative Therapy (OMT) is a set of osteopathic techniques that involves manipulation of the musculoskeletal system using the hands. It offers a supplement to standard modes of diagnosis and treatment, and is a key component of the osteopathic holistic approach to medicine.

Despite growing numbers of osteopathic physicians in the United States, OMT continues to be an underutilized asset in a plethora of medical conditions. With the merger of osteopathic and allopathic residency programs, restructuring of standardized curricula to a pass/fail format, and further changes uniting the two tracks of physician education, OMT remains one of the few facets …

The Therapeutic Benefits Of Attunement Through Lindy Hop, Sarah Trowbridge

Expressive Therapies Capstone Theses

Dance/movement therapy (DMT) was developed as a tool to aide in therapeutic healing. A foundational aspect of DMT is attunement, the emotional/kinesthetic connection between two people that allows for meaningful and healing bonds to emerge. Lindy Hop is a partnered dance that fosters an environment of attunement, as it is accessed both subconsciously and consciously. This research explores Lindy Hop as a possible method of therapeutic treatment. The literature indicates the physiological need for attunement and how safety plays a key role in strengthening senses of self-identity, nervous system development, and worldview. Four experienced Lindy Hoppers were recruited to engage …

Impact Of Acute Exercise On Micrornas Related To Concussion Symptoms, Emily Work

UNO Student Research and Creative Activity Fair

Impact of acute exercise on microRNAs related to concussion symptoms

Concussions, or traumatic brain injury (TBI), are a serious medical problem affecting approximately 1.7 million people in the United States each year. Current tools for analysis of concussion include the Glasgow Coma Scale, SCAT5, computerized topography (CT) and magnetic resonance imaging (MRI), however, these tools are typically not indicative of the range and severity of symptoms a patient may experience. Recent studies have explored the use of microRNAs as a biomarker for TBI severity in patients who have already experienced a TBI. We seek to investigate the microRNA levels in …

Center for Brain, Biology, and Behavior: Faculty Publications

In recent years, multivariate pattern analysis (MVPA) has been hugely beneficial for cognitive neuroscience by making new experiment designs possible and by increasing the inferential power of functional magnetic resonance imaging (fMRI), electroencephalography (EEG), and other neuroimaging methodologies. In a similar time frame, “deep learning” (a term for the use of artificial neural networks with convolutional, recurrent, or similarly sophisticated architectures) has produced a parallel revolution in the field of machine learning and has been employed across a wide variety of applications. Traditional MVPA also uses a form of machine learning, but most commonly with much simpler techniques based on …

The Potential Of Raman Spectroscopy In The Diagnosis Of Dysplastic And Malignant Oral Lesions, Ola Ibrahim, M. Toner, Steven Flint, Hugh Byrne, Fiona Lyng
