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 ...
Use of geographic information systems and remote sensing as automated tool for variable rate irrigation prescriptions
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Economic as well as water shortage pressure on agricultural use of water has placed added emphasis on efficient irrigation management. Center pivot ...
Modelling and analysis of energy metabolism in postmortem muscle
(University of Missouri--Columbia, 2022)
is negligible (0.0043 after 24 hours). Analysis of the effects of various factors on pH variations showed that electrical stimulation affects pH primarily through ATP hydrolysis and anaerobic glycolysis. The initial muscle oxygen saturation and phosphocreatine...
Time delay compensation in finite-order models of acoustic wave propagation in homogenous media
(University of Missouri--Columbia, 2011)
function of wave transmission for an arbitrary number of elements. Results from the two methods were verified with transfer functions computed from state space models developed in the time domain. The transfer functions were used to evaluate the model time...
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. ...
Manure management using precision agriculture
(University of Missouri--Columbia, 2010)
The overall purpose of this project was to develop and implement a manure application record system that was solely based on Global Positioning Systems (GPS). This system will have the ability to provide steering and ...
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 ...
Development of an online planning tool for designing terrace layouts
