[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 ...
Single-molecule investigation and nanopore-integrated biochip
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Chlorella-encoded membrane protein Kcv was synthesized and purified in vitro. By co-synthesis and assembly of wild type with tagged version of Kcv, ...
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 ...
Gating of CFTR chloride channels : distinct closed states revealed by the action of AMP-PNP
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The CFTR chloride channel is gated by ATP through an irreversible gating cycle driven by an input of free energy of ATP hydrolysis. The open state of ...
Polyurethane foams from novel soy-based polyols
(University of Missouri--Columbia, 2008)
Polyurethane foams and molded plastic films were prepared by reacting isocyanates with polyols containing 50% of vegetable oil-based polyols and 50% of petroleum-based polyols. The vegetable oil-based polyols included ...
Optical characterization of skeletal muscles
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The optical absorption and reduced scattering coefficients of bulk skeleton muscle were measured by fitting the diffusion model to spatially resolved ...
Development of a human immunodeficiency virus (HIV-1) biosensor utilizing liquid core waveguides
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Millions of individuals are diagnosed each year with Human Immunodeficiency Virus Type 1. Each day more individuals are receiving antiretroviral ...
Effects of oxidative stress and Alzheimer's amyloid-beta peptide on astrocytes
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Oxidative stress and deposition of amyloid-[beta] peptide (A[beta]) in brains have been hypothesized as causes of Alzheimer's disease (AD), and research ...
Logistic modeling of a biomass utilization system
(University of Missouri--Columbia, 2009)
A logistic model was developed for a biomass utilization system and implemented in ExtendSim. The model allows for system simulation and analysis of biomass supply chain in terms of economic viability and energy balance. ...
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 ...
Detection of cold flow properties of diesel and biodiesel fuel using optical sensor
