Perturbation of Circadian Neuronal Oscillators with Low-Intensity Magnetic Stimulation
(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
(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
(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
(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 ... -
Quantifying Double-Strand Breaks and Clustered Damages in DNA by Single-Molecule Laser Fluorescence Sizing
(East Carolina University, 2003-02)Fluorescence from a single DNA molecule passing through a laser beam is proportional to the size (contour length) of the molecule, and molecules of different sizes can be counted with equal efficiencies. Single-molecule ... -
Quantitative analysis and comparison of 3D morphology between viable and apoptotic MCF-7 breast cancer cells and characterization of nuclear fragmentation
(2017-09-08)Morphological changes in apoptotic cells provide essential markers for defining and detection of apoptosis as a fundamental mechanism of cell death. Among these changes, the nuclear fragmentation and condensation have ... -
RADIOSENSITIZATION OF PROSTATE CARCINOMA CELLS BY PEGYLATED METALLIC NANOPARTICLES TO PROTON IRRADIATION
(East Carolina University, 2023-05-01)One of the main goals of cancer radiation therapy is to reduce the dose to healthy tissues while maximizing the dose to malignant tissue. A special class of materials known as "radiosensitizers" has emerged that can help ...
