Synthesis And Analytical Evaluation Of Folate Conjugates For Use In Cancer Cell Detection, Sneha Reddy Kuthuru

All Capstone Projects

Recent clinical studies have shown the importance of folate receptor in drug delivery system as they increase the potency and reduce toxicity of many cancer therapies. The folate receptor alpha ( FR-a) binds with high affinity for folic acid and serves for receptor mediated transport of folate into cells. Folate is necessary for DNA metabolism and thus it is speculated that rapidly dividing cancer cells have an increased requirement for folic acid. It is known that FR-a levels are elevated in specific malignant diseases (solid tumors, leukemia) and thus the FR receptor serves as useful targeting moiety for the diagnosis …

The Effect Of Particle Size On Hydrolysis And Modeling Of Anaerobic Digestion, Saad Aldin

Electronic Thesis and Dissertation Repository

Batch experiments were performed to investigate the effect of particulate protein particle size on the hydrolysis of casein in anaerobic degradation. While particle size did not affect the ultimate protein degradation efficiency, the hydrolysis rate coefficient increased from 0.034 to 0.298 d-1 with the change in specific surface area from 0.01 to 0.192 m2/g. The maximum methane production rate was affected by the particle size change, although the ultimate amount of methane produced was approximately the same despite the change in specific surface area. A mathematical relationship between the hydrolysis rate coefficient and specific surface area was developed and a …

Molecular Simulations Of Adsorption And Diffusion In Metal-Organic Frameworks (Mofs), Ruichang Xiong

Doctoral Dissertations

Metal-organic frameworks (MOFs) are a new class of nanoporous materials that have received great interest since they were first synthesized in the late 1990s. Practical applications of MOFs are continuously being discovered as a better understanding of the properties of materials adsorbed within the nanopores of MOFs emerges. One such potential application is as a component of an explosive-sensing system. Another potential application is for hydrogen storage.

This work is focused on tailoring MOFs to adsorb/desorb the explosive, RDX. Classical grand canonical Monte Carlo (GCMC) and molecular dynamic (MD) simulations have been performed to calculate adsorption isotherms and self-diffusivities of …

Optimization Of Environmental Conditions To Maximize Carbon Dioxide Sequestration Through Algal Growth, Kenneth M. Karcher

Theses and Dissertations

The micro-alga Chlorella vulgaris was cultivated under a variety of environmental conditions in various culture media solutions to assess and optimize growth rate and biomass productivity. Efforts during this work investigated growth parameters at the micro-scale in an air-lift bubble system with the goal of interpreting performance characteristics that can be applied to a larger serpentine tubular Photo-bioreactor. Maximum growth rates and biomass yields were 0.65 d^-1 and 2.003 g biomass/L and achieved in seven days using urea in de-ionized water under a 24:0 Photoperiod (Light:Dark). Additionally, growth rates and biomass yields of 0.65 d^-1 and 1.964 g …

Targeted Polymeric Biomaterials For The Prevention Of Post Surgical Adhesions, John M. Medley

University of Kentucky Doctoral Dissertations

Despite recent advances in surgical technique and the development of numerous therapeutic agents, the formation post surgical adhesions (PSA) continues to cause complications for many patients. In this research, we have employed a rational system to develop a novel treatment to address this clinical need. Based on an understanding of the biochemical events that lead to PSA formation, a series of targeted polymeric biomaterials was designed to interrupt the fibrin gel matrix propagation and suppress PSA formation.

Using group transfer polymerization, a series of well controlled block copolymers of polyacrylic acid and poly(ethylene glycol-methacrylate) based materials was synthesized. Subsequent functionalization …
