Protocol Variation Analysis Of Whole Brain Ct Perfusion In Acute Ischemic Stroke, Peter T. Heiberger

UNLV Theses, Dissertations, Professional Papers, and Capstones

Computed tomography perfusion (CTP) analysis is a rapidly advancing imaging modality that is improving diagnosis of brain abnormalities in patients suffering from hemorrhagic or ischemic stroke, traumatic brain injury, vascular occlusion and numerous other conditions. Through the advancements of computed tomography (CT) imaging, including the introduction of the 320-detector row CT with a 16 centimeter range in the z-axis enabling whole brain CTP, perfusion analysis now has a significantly increased clinical utility that is useful for both diagnosis and treatment of central nervous system (CNS) conditions. This study focuses on the procedural and analytical approach to the diagnostic evaluation of …

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 Effects Of Cellular Theta Breathing Meditation On Cell Mediated Immune Response: A Controlled, Randomized Investigation Of Altered Consciousness And Health, Marjorie D. Hardgrave

UNLV Theses, Dissertations, Professional Papers, and Capstones

Medical anthropology is well positioned to make contributions to consciousness research based on biocultural approaches that integrate methodologies from the biological, behavioral and social sciences to explore aspects of human health. The ubiquity and perseverance of health related activities involving altered states of consciousness (ASC) across cultures past and present suggest that these potentials are deeply rooted in human sociocultural evolution. Analyzing the relationship between immune function and meditative ASC represents an effort to empirically investigate the adaptive value of these human potentials.

A controlled, randomized investigation of two meditation practices was conducted at the University of Nevada, Las Vegas …
