The Effect Of Spinal Cord Injury On Vagal Afferents., April N. Herrity

Electronic Theses and Dissertations

Spinal cord injury (SCI) is a significant public health concern that leaves patients with a multitude of life-long disabilities. Major complications of SCI apart from paralysis, include deficits in bladder and bowel function. Lower urinary tract dysfunction continues to remain a top priority issue affecting quality of life for this population. The majority of visceral organs receive a dual sensory innervation from both spinal nerves as well as the vagus nerve. Following SCI, the vagus nerve is a potential pathway through which information from regions below the level of a spinal injury can travel directly to the brainstem, bypassing the …

Role Of Astrocyte Network In Edema After Juvenile Traumatic Brain Injury, Andrew Minoru Fukuda

Loma Linda University Electronic Theses, Dissertations & Projects

Juvenile traumatic brain injury (jTBI) is the leading cause of death and disability in young children and adolescents. Despite its lasting detrimental effects on the developing brain, no pharmacological treatment exists. One of the pathological hallmarks of jTBI is edema. Astrocytes play a key role in the edema process, and have been hypothesized that numerous astrocyte networks allow communication and propagation of edema and secondary injury spread. Two key astrocyte proteins are hypothesized to have a central role in the edema process: Aquaporin 4 (AQP4) and Connexin 43 (Cx43). AQP4 is expressed extensively in astrocyte endfeet, which surrounds the blood …

Performance Evaluation Of Material Decomposition Using Rapid Kvp-Switching Dual-Energy Ct For Assessing Bone Mineral Density, John M. Wait

Dissertations & Theses (Open Access)

Osteoporosis is diagnosed by assessing the bone mineral density (BMD) of the trabecular bone, and has previously been characterized with dual-energy x-ray absorptiometry (DXA) or single-energy computed tomography (SECT). Dual-energy computed tomography (DECT) is able to create two three-dimensional sets of images representing the densities of two materials in a given basis pair. DECT is theoretically capable of providing a true density measurement of trabecular bone material with the proper material basis pair.

Using the rapid kVp-switching GE HD750 scanner, the concentrations of various solutes were assessed in two-material syringe-phantoms in different experimental conditions with DECT material density images, SECT …

Osteopathic Manipulative Medicine (Omm) And Reduction Of Nsaid Use In Low Back Pain: A Pilot Study, Kristopher Kelly

PCOM Biomedical Studies Student Scholarship

This randomized controlled pilot study is to determine if a combination of muscle energy and soft tissue techniques can reduce the amount of daily NSAID use in patients suffering from chronic non-specific low back pain (CNSLBP). Osteopathic manipulative treatment has been shown to be useful in treating low back pain. However, its role in reducing daily NSAID use in CNSLBP patients is unclear. This study was conducted at PCOM from January 2014 to April 2014. By design, patients were to be randomized into either a treatment group consisting of OMT or a control group consisting of a sham OMT. Of …

Evaluation Of Tissue-Engineered Tendon Enthesis Polymer Constructs, Joshua A. Bundy Bs, Mary Beth Wade Phd, Hitomi Nakao Md, Phillip Mcclellan Phd, Qing Yu Phd, Robin Jacquet-Childs Ms, William J. Landis Phd

Williams Honors College, Honors Research Projects

Both scientists and clinicians have proposed tissue engineering as the future of medicine. The possibilities for tissue engineering, that is, fabrication of tissues and organs in the laboratory and their translation to patients, appear to be endless, and many believe that this new approach in medicine will result in abolishing many common ailments, injuries, and congenital defects. Injuries to a tendon enthesis, the normal tissue connection between tendon and bone, are of particular concern to clinicians because of their frequency and failure to repair as a result of surgery. While these injuries may not be life threatening, they can certainly …
