Integrating Galectin-3 Into A Computational Model Of Cardiac Fibrosis Progression, Adam Pieratt
Integrating Galectin-3 Into A Computational Model Of Cardiac Fibrosis Progression, Adam Pieratt
Chemical Engineering Undergraduate Honors Theses
Cardiac fibrosis, a large contributor to heart failure, is the excessive accumulation of extracellular matrix in response to stress or injury. There are no approved treatments for cardiac fibrosis, and targeting specific species involved creates complex problems for drug development, so a computational model of the cardiac fibroblast signaling network can be used to observe the interactions involved in the progression of cardiac fibrosis. In this paper, a new protein called galectin-3 is integrated into this existing model, and connections are established to expand the coverage of the network. The additions are described, simulated using Netflux biological system simulation software, …
Drug-Facilitated Sexual Assault At The University Of Arkansas, Barrett Weidman
Drug-Facilitated Sexual Assault At The University Of Arkansas, Barrett Weidman
Chemical Engineering Undergraduate Honors Theses
This work was written to fulfill two main purposes. First, to help survivors of Drug-Facilitated Sexual Assault (DFSA) process their experience by compiling the toxicological, pharmacological, and distribution of the three most used date-rape drugs. Second, to gauge the knowledge and interest of University of Arkansas students regarding drug impairments, sexual assault education, and bystander intervention training. A survey was conducted for the latter and revealed that 91.6% of students believe the University’s existing sexual assault prevention education and bystander intervention training have room for improvement. Also, 37.1% of students who have received this education report that the programming does …
Peptoid And Antibody-Based Gfp Sensors, Solomon Isu
Peptoid And Antibody-Based Gfp Sensors, Solomon Isu
Graduate Theses and Dissertations
In this work, we have made and characterized a pair of immunobiosensors for detecting the green fluorescent protein (GFP) in an aqueous matrix. An anti-GFP antibody-based biosensor was assembled to detect GFP, while a novel peptoid (N-substituted oligomers of glycine designated as IOS-1) biosensor was also assembled for GFP detection. A quartz crystal microbalance (QCM) gold sensor was used as the supporting substrate for self-assembly of the immunobiosensors. Gravimetric measurements of the QCM gold sensor during immunobiosensor construction and operation were available in real-time using a QCM instrument. X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, and Fluorescence microscopy were used …
Development Of A Simple Handheld Biosensor For Waterborne Pathogens, Bryce C. Jones
Development Of A Simple Handheld Biosensor For Waterborne Pathogens, Bryce C. Jones
Chemical Engineering Undergraduate Honors Theses
Current methods of detecting waterborne pathogens involve testing strips which take 24-48 hours to yield results, or require expensive equipment in order to function. In minimalist environments, these two technologies are not always applicable to test water quality. With the emergence of a new method of PCR, named LAMP PCR, it is possible to quickly and accurately detect pathogen DNA in a water sample. In order to scale this technique into a simple device, the aspects of the reaction must be accommodated, and a visual detection method chosen. A handheld device which keeps the isothermal LAMP PCR stable for the …
The Production Of Biobutanol From Biomass Via A Hybrid Biological/Chemical Process, Thomas Melvin Potts
The Production Of Biobutanol From Biomass Via A Hybrid Biological/Chemical Process, Thomas Melvin Potts
Graduate Theses and Dissertations
Biobutanol use as a fuel began in the late 19th century. Problems remain in economic viability. A review of the state of the art and need for technical advances is presented.
The technical potential of producing biofuel from a naturally occurring macroalgae was studied. The algae grow in Jamaica Bay, New York City, in contaminated water. The process consisted of mechanical harvesting, drying, grinding, and acid hydrolysis to form an algal sugar solution. Clostridium beijerinckii and C. saccharoperbutylacetonicum were used in an acetone butanol ethanol (ABE) fermentation to make butanol. Fermentation was followed by distillation Butanol concentrations during fermentation reached …
Peptoid Based Slide Coatings For Disease Detection Via Elisa Microarray Analysis, Melissa Lea Hebert
Peptoid Based Slide Coatings For Disease Detection Via Elisa Microarray Analysis, Melissa Lea Hebert
Graduate Theses and Dissertations
Poly-N-substituted glycines (peptoids) are a very versatile family of synthetic molecules that can be customized for any number of applications. In this study, we chose to use peptoids as a foundation for sandwich ELISA microarray analysis with a long term goal of creating an early detection device for complex diseases such as cancer. The peptoids were designed to self-assemble into microspheres to be used in coatings on the surface of the microarray substrates to increase the surface area available for antibody attachment. This increased antibody density would lead to an increase in the microarray analysis sensitivity and dynamic range. Studies …
