Stimuli-Responsive Hydrogel Microdomes Integrated With Genetically Engineered Proteins For High-Throughput Screening Of Pharmaceuticals, Sylvia Daunert, Sapna K. Deo, Jason Douglas Ehrick, Tyler William Browning, Leonidas G. Bachas

Chemistry Faculty Patents

A hydrogel microdome that can swell in response to a stimuli or target molecule is formed by polymerizing a mixture comprising a monomer capable of forming a hydrogel with a biopolymer. An array of hydrogel microdomes can be formed on a substrate by microspotting the mixture and polymerizing. The array can be used for high-throughput screening of analytes as well as for use as an actuator and biosensor using the swelling property of the hydrogel.

Bootstrap Enhanced N-Dimensional Deformation Of Space With Acoustic Resonance Spectroscopy, David John Link

University of Kentucky Doctoral Dissertations

Acoustic methods can often be used with limited or no sample preparations making them ideal for rapid process analytical technologies (PATs). This dissertation focuses on the possible use of acoustic resonance spectroscopy as a PAT in the pharmaceutical industry. Current good manufacturing processes (cGMP) need new technologies that have the ability to perform quality assurance testing on all products. ARS is a rapid and non destructive method that has been used to perform qualitative studies but has a major drawback when it comes to quantitative studies. Acoustic methods create highly non linear correlations which usually results in high level computations …

Pattern Recognition Integrated Sensing Methodologies (Prisms) In Pharmaceutical Process Validation, Remote Sensing And Astrobiology, Thaddaeus S. Hannel

University of Kentucky Doctoral Dissertations

Modern analytical instrumentation is capable of creating enormous and complex volumes of data. Analysis of large data volumes are complicated by lengthy analysis time and high computational demand. Incorporating real-time analysis methods that are computationally efficient are desirable for modern analytical methods to be fully utilized. The use of modern instrumentation in on-line pharmaceutical process validation, remote sensing, and astrobiology applications requires real-time analysis methods that are computationally efficient.

Integrated sensing and processing (ISP) is a method for minimizing the data burden and sensing time of a system. ISP is accomplished through implementation of chemometric calculations in the physics of …

Imide-Functionalized Conjugated Polymers: Synthesis, Structure-Property And Device Studies, Xugang Guo

University of Kentucky Doctoral Dissertations

Organic semiconductors are widely studied as potential active components for consumer electronics due largely to their easily tuned properties and the promise of lower-cost solution-based processing technology. Imide-functionalized organic small molecule compounds have been one of the more important and studied organic semiconductors. However, very few imide-functionalized conjugated polymers have been reported in the literature. The body of this dissertation focuses on the synthesis, structure-property and device studies of imide-functionalized conjugated polymers. Reasons for choosing arylene imides as polymer building blocks include: a) they impart low-lying LUMOs to polymers, allowing band-gap engineering through choice of comonomers with variable electron-donating ability; …

Investigations Of S-Glutathionylation Of Brain Proteins In The Progression Of Alzheimer's Disease And Of A Potential Glutatione Mimetic As A Treatment Of Alzheimer's Disease, Shelley Faye Newman

University of Kentucky Doctoral Dissertations

Alzheimer’s disease (AD) is a neurodegenerative disorder characterized by neurofibrillary tangles, senile plaques and loss of synapses. Many studies support the notion that oxidative stress plays an important role in AD pathogenesis. Previous studies from our laboratory employed redox proteomics to identify oxidatively modified proteins in the AD inferior parietal lobule (IPL). The proteins were consistent with AD pathology and have been central to further investigations of the disease. The present study was focused on the identification of specific targets of protein S-glutathionylation in AD, early AD (EAD), and mild cognative impairment (MCI) using a redox proteomics approach. In AD …

Alterations Of Zinc Transporters In Alzheimer's Disease, Ganna Lyubartseva

University of Kentucky Doctoral Dissertations

Alzheimer’s disease (AD), one of the major causes of disability and mortality in Western societies, is a progressive age-related neurodegenerative disorder. Increasing evidence suggests the etiology of AD may involve disruptions of zinc (Zn) homeostasis. We hypothesize that disruption of Zn homeostasis leads to alterations of Zn transporter (ZnT) proteins, resulting in increased production of neurotoxic amyloid beta (Aβ) peptide in AD brain. To address this hypothesis we carried out the following studies.

1. We characterized alterations of ZnT-1, ZnT-4 and ZnT-6 in the brain of preclinical AD (PCAD) subjects, who show no overt clinical manifestations of AD but demonstrate …
