The data from the completed surveys was collected and analyzed. The data …

Development Of Novel Biomarkers In Cancer: Detection Of Circulating Mir-141 As A Potential Prognostic Marker For Prostate Cancer, Jason Cadaoas Gonzales

UNLV Theses, Dissertations, Professional Papers, and Capstones

Prostate cancer (CAP) is the most common epithelial malignancy and the second leading cause of cancer deaths in American men. The identification of predictive and prognostic biomarkers in CAP patients is critical for improving clinical outcomes. Although the measurement of prostate-specific antigen (PSA) and radiographic studies are clinically approved to predict response to therapy, these tests can oftentimes prove to be inadequate in certain patients. Thus, it is important to discover new biomarkers to improve chances of survivability. We and others have shown that longitudinal measurements of circulating tumor cells (CTC) and lactate dehydrogenase (LDH) may aid in predicting response …

The Determinants Of Colorectal Cancer Survival Disparities In Nevada, Lucas N. Wassira

UNLV Theses, Dissertations, Professional Papers, and Capstones

Different population groups across Nevada and throughout the United States suffer disproportionately from colorectal cancer and its after-effects. Overcoming cancer health disparities is important for lessening the burden of cancer. There has been an overall decline in the incidence of and mortality from colorectal cancer (CRC). This is likely due, in part, to the increasing use of screening procedures such as Fecal Occult Blood Test (FOBT) and/or endoscopy, which can reduce the risk of CRC mortality by fifty percent. Nevertheless, screening procedures are routinely used by only fifty percent of Americans aged fifty years and older. Despite overall mortality decreasing …

Development Of Software To Estimate Pressures On The Residual Limbs Of Amputees By Means Of A Pylon Mounted Transducer, Malli K. Yalamanchili

UNLV Theses, Dissertations, Professional Papers, and Capstones

The alignment of prosthesis has been recognized as one of the main factors that determine successful prosthetic outcomes for trans-tibial amputees. Alignment is defined as the relative position and orientation of the prosthetic components. Misalignment can result in changes in the position and orientation of the joints of the leg and moments experienced by them during gait, increases in energy use, and discomfort or even tissue breakdown at the socket/stump interface. Hence it is very important to align the prosthesis in correct manner. Gait analysis can be used to examine the effects of incorrect alignment of the prosthesis during gait. …

Donepezil And Galanin Interactions In An Animal Model Of Alzheimer’S Disease, Jonathan J. Sabbagh

UNLV Theses, Dissertations, Professional Papers, and Capstones

Alzheimer's disease (AD) is a neurodegenerative disorder marked by a progressive loss of cognitive function. One of the neurobiological hallmarks of AD is a progressive loss of cholinergic neurons and a decrease in the amount of acetylcholine in the brain. Pharmacological therapies have targeted the cholinergic system, specifically first-line, palliative treatment using acetylcholinesterase (AChE) inhibitors, such as donepezil. Donepezil has been shown to increase cholinergic tone and ameliorate some of the cognitive deficits in AD patients. Galanin, a neuropeptide that inhibits the evoked release of several neurotransmitters including acetylcholine as well as modulates seveal intracellular cascades, is overexpressed in AD …

Macrophages Loaded With Gold Nanoshells For Photothermal Ablation Of Glioma: An In Vitro Model, Amani Riad Makkouk

UNLV Theses, Dissertations, Professional Papers, and Capstones

The current median survival of patients with glioblastoma multiforme (GBM), the most common type of glioma, remains at 14.6 months despite multimodal treatments (surgery, radiotherapy and chemotherapy). This research aims to study the feasibility of photothermal ablation of glioma using gold nanoshells that are heated upon laser irradiation at their resonance wavelength. The novelty of our approach lies in improving nanoshell tumor delivery by loading them in macrophages, which are known to be recruited to gliomas via tumor-released chemoattractive agents. Ferumoxides, superparamagnetic iron oxide (SPIO) nanoparticles, are needed as an additional macrophage load in order to visualize macrophage accumulation in …

The Influence Of Perspective And Gender On The Processing Of Narratives, Jeremy A. Houska

UNLV Theses, Dissertations, Professional Papers, and Capstones

The overarching aim of this research was to examine potential boundary conditions to situation model construction (Experiment 1) and narrative-based persuasion (Experiment 3). Variables such as narrative perspective (i.e., 2nd or 3rd person) and matched characteristics with the reader (i.e., participant-protagonist gender match) were first examined using situation model updating (Experiment 1) and behavioral measures (Experiment 3) as dependent measures. It was expected that situation model updating would be more likely for narratives written in the 2nd person perspective and with a participant-protagonist gender match. It was uncertain, however, for health promotion narratives, whether these manipulations would increase the likelihood …

The Live Experience Of Non-Degree Learners From A Time Modified Traditional Baccalaureate In Nursing Program, Stephanie S. Deboor

UNLV Theses, Dissertations, Professional Papers, and Capstones

By the year 2016, it is projected that a million new and replacement nurses will be needed throughout the United States. The traditional 4-year baccalaureate program alone cannot adequately sustain this demand. The immediacy of the current nursing shortage demands our educational systems respond by building and maintaining a workforce that is sufficient to support the health care needs of our society. In an attempt to meet this challenge, nursing schools around the country began exploring the option of creating accelerated programs for those who already possess a bachelor's degree in another field without compromising the integrity and quality of …

Compared to other North American indigenous populations, Southwest Alaskan Yupiit exhibit very low rates of type 2 diabetes despite the occurrence of common risk factors. Contemporary Yupiit obtain a substantial portion of their calories from traditional foods, which contain high amounts of omega-3 polyunsaturated fatty acids. Epidemiological and experimental animal research has linked glucose and insulin homeostasis with a diet high in omega-3s. This study used an experimental animal model to explore potential diabetes protective effects (for adult offspring) of prenatal maternal nutrition modeled on traditional locally-obtained Yupiit diets. The results of this study showed that the adult offspring whose …

Oral Cancer In Nevada: A Public Health Perspective, Karl Kingsley

UNLV Theses, Dissertations, Professional Papers, and Capstones

Cancer is the second leading cause of death in the United States, and oral cancer remains the eighth leading cause of cancer death among US males. Although previous epidemiologic studies have found that overall rates of cancer, including oral cancer, have declined in the US in recent decades – these declines are neither uniform nor consistent within this population. Anecdotal evidence has suggested that rates of oral cancer in Nevada are relatively high, although no evidence was available to support these assertions.

Oral Cancer Epidemiology: Based upon this information, a detailed and thorough epidemiologic examination of oral cancer rates in …

Factors Associated With Blood Lead Levels Of Children In Southern Nevada, Mackenzie Suzanne Burns

UNLV Theses, Dissertations, Professional Papers, and Capstones

Exposure to lead continues to be a public health concern, particularly for young children. The Centers for Disease Control and Prevention report that approximately 250,000 children currently have blood lead levels (BLLs) above the level at which adverse health effects are apparent and intervention is recommended (10μg/dL). National surveillance data on childhood lead exposure has been collected for children under the age of 6 years old since 1995. However, not until 2006 did a program begin in Nevada (limited to Clark County); therefore, statewide data about childhood lead exposure in Nevada remains limited. The goal of this study was to …

The Role Of Visual, Vestibular, And Somatosensory Systems In Postural Balance, Mary Grace Gaerlan

UNLV Theses, Dissertations, Professional Papers, and Capstones

The integration of visual, vestibular, and somatosensory components are used to maintain one's postural balance. Postural control changes over time and body sway increases with age. The different sensory systems begin to develop and refine starting when children are young, while in older adults it begins to decline. Hence, it is important to study the changes that occur in postural balance. There is very little known about balance of younger adults. If balance issues are identified early in adult life it is possible to prevent exacerbation of balance decline as one ages. If nurse practitioners are aware of what dominant …
