Development of high-resolution optical tomography with a larger-size projection acquisition
(University of Missouri--Columbia, 2007)
In the industrial countries, the mortality from arteriosclerosis and cardiovascular diseases has been decreased, but they remain the most common circulatory disease. Recently, new tissue engineering technologies such as ...
Modeling of phototransduction in vision systems
(University of Missouri--Columbia, 2007)
To improve the usefulness of the electroretinogram (ERG) in identifying the sites and mechanisms of adaptation, development and disease processes, a quantitative model was developed based on the biochemical reaction kinetics ...
Development of a flexible image-based approach for studying signal transduction in isolated arterioles
(University of Missouri--Columbia, 2007)
Myogenic constriction in arterioles occurs when membrane tension leads to smooth muscle depolarization and voltage-gated calcium channel activation. A barrier to understanding the exact signaling events is the limited ...
Characterization of membrane viscosity changes with the novel molecular rotor FCVJ
(University of Missouri--Columbia, 2007)
Membrane viscosity can be defined as the "thickness" of a cell membrane. Membrane viscosity conditions are a useful indicator of cell health. Many diseases have been reported to induce changes in afflicted cell membrane ...
Photoacoustic discrimination of viable and thermally coagulated blood for burn injury imaging
(University of Missouri--Columbia, 2007)
Early and accurate determination of burn depth is crucial to monitoring and treatment of the burn wound. One such treatment, surgical excision and grafting, involves removal of necrotic tissue from the wound and replacing ...
Synthesis and application of semiconductor quantum dots in novel sensing applications
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This thesis details the synthesis of CdSe/ZnS semiconductor nanocrystals (quantum dots). These quantum dots (QDs) show very interesting optical properties ...
Detection of CD4 and CD8 t-lymphocytes and HER2 breast cancer biomarker using the opto-fluidic ring resonator biosensor
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] We have demonstrated label-free detection of CD4+ and CD8+ T-Lymphocytes and HER2 breast cancer biomarker using the opto-fluidic ring resonator (OFRR) ...
Aptamer encoded nanopores as single molecule sensors
(University of Missouri--Columbia, 2008)
We have created a low noise, calibrated, molecular-scaled pore. The nanopore is formed either by micro-forge polishing or external penetration of the nanocavity sealed in the pipette terminal. The nanopore fabrication is ...
CPLA2: key enzyme for astroctytic cell membrane phase property change induced by abeta
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The interaction of amyloid beta peptide (A[beta]) and cell membrane is believed to be the basis of its biological function including its toxicity to ...
A fiber-optic confocal scanner for scattering tissue
(University of Missouri--Columbia, 2009)
Confocal microscopy has become an important diagnostic tool in examining scattering tissues. The high resolution of confocal microscopy and its optical sectioning capabilities lend itself as a desirable modality in examining ...
Investigative study of long-term packaging effects and donor characteristics on acellular dermis scaffolds
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Acellular tissue sources have become progressively popular for a variety of tissue engineering and medical applications, such as soft tissue augmentation, ...
Development and applications of label-free optofluidic ring resonator biosensor
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This dissertation presents the development and applications of label-free optofluidic ring resonator (OFRR) sensor platform. The OFRR sensor naturally ...
Optical glucose nanobiosensor encapsulated in erythrocytes
(University of Missouri--Columbia, 2007)
An implantable glucose biosensor encapsulated in erythrocytes, Red Blood Cells (RBC), will become a method for continuously measuring blood glucose concentration in diabetics. In 2005, the American Diabetes Association ...
Nano- and micro-scale studies of exocytosis
(University of Missouri--Columbia, 2007)
Neurons and neuroendocrine cells contain vesicles packed with hormones or neurotransmitters. Upon appropriate stimulation, a rise in intracellular Ca2+ concentration triggers the fusion of vesicles with the outer membrane ...
