MODIFICATION OF CELL SURVIVAL RATES BY CERIUM OXIDE NANOPARTICLES FOR EXPOSURE TO PROTON RADIATION
Boyd, Christopher Michael (East Carolina University, 2017-05-03)Radiation therapy is a well-established and widely used treatment for a variety of malignancies in the human body. Current radiotherapy methods most frequently use x-rays to deliver a lethal dose to tumors with sufficient ... -
Mutation of tandem repeats in fibrin's alpha-C region
Spangler, Sarah Elizabeth (East Carolina University, 2018-01-19)Cardiovascular problems such as myocardial infarctions and emboli are the number one killers in the United States. These health concerns arise from blood clotting unnecessarily in the veins or arteries. Studies have shown ... -
Optical and dielectric properties of metallic calcium, modeled generalized oscillator strength function of calcium, interaction cross sections of electrons, protons, and alpha particles with calcium
Jorjishvili, Irakli G. (East Carolina University, 2013)An analysis of the optical and the dielectric properties of calcium, determined from the literature, was performed. The optical functions of calcium were used for a calculation of the energy loss function of calcium. The ... -
Optical Pulling, Optical Deflection, and Optical Trapping of Single Airborne Particles using Negative Photophoresis
Hart, Adam (East Carolina University, 2016-05-03)Optical manipulation is the use of light to control the motion of objects. This thesis focuses on the development of optical transportation technology via optical pulling with application to the characterization of single ... -
Optimizing graphene oxide reduction via laser irradiation
Osenga, Austin Patrick (East Carolina University, 2017-01-04)The present report discusses a single step method to reduce graphene oxide via laser irradiation. A computer numerically controlled laser engraver equipped with a 450nm laser diode was engineered to conduct this research. ... -
Perturbation of Circadian Neuronal Oscillators with Low-Intensity Magnetic Stimulation
Kassahun, Bineyam T. (East Carolina University, 2019-04-23)Circadian neuronal oscillatory dynamics are perturbed substantially in numerous neuropsychiatric diseases, such as Alzheimer's, Parkinson's, and depression. Moreover, desynchronization of neuronal oscillators complicates ... -
PROFILING EFFUSION CELLS BY QUANTITATIVE ANALYSIS OF MORPHOLOGY AND DIFFRACTION IMAGING PATTERNS
Al-Qaysi, Safaa (East Carolina University, 2019-04-12)Profiling cells in human pleural and peritoneal effusion (PPE) samples is an essential task for cytological diagnosis of cancers and patient management. Conventional PPE cytology of a PPE sample is labor intensive and its ... -
A PROPOSED METHODOLOGY TO ASSESS HDR [superscript]192Ir RADIAL DOSE WITH FRICKE DOSIMETRY
Benhabib, Sidi Mohammed (East Carolina University, 2011)The radial absorbed dose to water, D(r,theta), a quantity not yet directly measured with primary standards, was assessed with the Fricke solution which has been considered as an absolute aqueous solution to perform dosimetry. ... -
Protection and Sensitization of Human Cells to Proton Radiation by Cerium Oxide Nanoparticles
Carlson, Nathan B (East Carolina University, 2017-07-17)In radiation therapy for the treatment of cancer, there is demand for novel approaches that will improve tumor cell killing while protecting healthy tissue. One such approach that has shown considerable promise is the ... -
Role of Blood Cytokine Levels and Adiposity in Myocardial Infarction Recurrence
Gawdi, Rohin (2018-05)Risk factors for myocardial infarction (MI) are important as cardiovascular disease is the leading cause of death. In fact, approximately one third of adults having an MI will have another in six years. The purpose of this ... -
Secondary Electron Emission Yields from Fast Fluorine Ions on Copper and Amorphous Solid Water Foils
McLawhorn, Steven L. (East Carolina University, 2011)The biological outcomes from charged particle radiation exposure are heavily influenced by the spatial patterns of energy distributed within the biological system. Monte Carlo track structure codes can be used to model ... -
Study of Morphology Based Cell Assay by Diffraction Imaging Flow Cytometry
Jiang, Wenhuan (East Carolina University, 2015)Development of an accurate and label-free method for single cell assay attracts intensive research efforts for its importance to cell biology research and clinicG14G7al applications. Flow cytometry is one of the most widely ...
