The role of sodium-calcium exchanger in the electrical activity of embryonic chicken heart
(University of Missouri--Columbia, 2008)
Heart is one of the most important organs of the body and also it is one of the first organs during to the development. The electrical activity of heart is essential for its function. It has been shown that the sodium-calcium exchanger (NCX...
A ratiometric fluorometer for reduced sensitivity against solvent artifacts
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] When measuring fluorescence emission intensity, both the dye concentration and the optical absorption properties of the solvent influence the measured ...
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 ...
Optical reflectance in fibrous tissues and skeletal muscles
(University of Missouri--Columbia, 2008)
We studied diffuse optical reflectance in two anisotropic biological tissues: high moisture soy extrudates and skeletal muscles. High moisture extrusion of soy proteins can produce healthy alternative protein sources that ...
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 tissue-engineered blood...
Optical stimulation of quantal exocytosis on transparent microchips
(University of Missouri--Columbia, 2007)
) film was sputter-deposited onto glass coverslips, which were then patterned into 24 cell-sized working electrodes (2̃0 [mu]m by 20 [mu]m). We loaded bovine chromaffin cells with acetoxymethyl (AM) ester derivatives of the Ca²⁺ cage NP-EGTA and Ca...
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 ...
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) ...
Detection of cold flow properties of diesel and biodiesel fuel using optical sensor
(University of Missouri--Columbia, 2006)
Identification of cloud point for biodiesel fuel can be used to optimize the performance of biodiesel fueled vehicles in cold weather. Cloud point is the temperature at which the smallest cluster of wax crystal is observed ...
Modeling of phototransduction in vision systems
(University of Missouri--Columbia, 2007)
cascade and experimental data. A set of differential equations were derived to predict the electrical response of photoreceptors to light and system identification was employed to determine the model parameters. When applied to wild-type and retina...
Single-molecule investigation and nanopore-integrated biochip
(University of Missouri--Columbia, 2008)
) folds into the G-quadruplex in the presence of cation. Trapping the TBA in the nanocavity of the alpha-hemolysin resulted in electrical characteristic changes to the pore conductance that revealed important molecular processes including spontaneous...
Development of electrospun synthetic bioabsorbable fibers for a novel bionanocomposite hernia repair material
(University of Missouri--Columbia, 2008)
In order to create a more durable and biocompatible hernia repair mesh, a novel bionanocomposite material based on the crosslinking of bioabsorbable polymer fibers to decellularized porcine diaphragm tissue is proposed. ...
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 ...
Study of human pupillary light reflex and its potential application in autism
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Pupillary light reflex (PLR) can be used as an objective and non-invasive method to evaluate certain brain functions. In this research, we developed ...
A novel PCR based DNA microanalyzer system for detection of viral genome
(University of Missouri--Columbia, 2006)
A micro-fluidic assay to quickly analyze microscopic samples of DNA is being developed for field applications. It consists of a micro-PCR chamber, micropumps, and micro-heaters. Additional components of the device include ...
Development of a capillary based helicobacter hepaticus biosensor
(University of Missouri--Columbia, 2006)
Helicobacter hepaticus causes hepatitis in mice. Infections with H. hepaticus can invalidate animal research studies and early detection helps curtail the spread of infection. The objective of this study was to develop a ...
Ratiometric techniques to determine fluid viscosity using molecular rotors
(University of Missouri--Columbia, 2007)
Molecular rotors exhibit viscosity-dependent quantum yield, potentially allowing measurements of fluid viscosity in non-mechanical manner. Several diseases are accompanied by blood plasma viscosity changes; therefore, a ...
Photoacoustic detection of metastatic melanoma in the human circulatory system
(University of Missouri--Columbia, 2006)
Detection of disseminating tumor cells can function as an early warning system, alerting the metastatic spread or recurrence of the disease. Early detection of such cells can result in preventative treatment of the disease ...
