Effect Of Selected Physical And Chemical Parameters On Crystal Violet Decolorization By Immobilized Laccase., Nur Atiqah Ismail

Student Works (2010-2019)

Synthetic dyes are used for coloration of various materials like textiles, leather and food. Wastewater from dyeing industries constitutes a threat to the environment as many synthetic dyes are often toxic, mutagenic and carcinogenic. Besides, light absorption is hindered by the dyes run-off creating problems to photosynthetic aquatic plants and algae. Biodegradation of waste dyestuff with enzymes provides a viable alternative compared to the often expensive physical/chemical methods. Laccase from Trametes versicolor was chosen in this study as it exhibits low substrate specificity and high ability to oxidize many pollutants which suggested its potential in wastewater treatment and bioremediation. The …

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 …

Evaluation Of Two Novel Aluminum-Free, Zinc-Based Glass Polyalkenoate Cements As Alternatives To Pmma Bone Cement For Use In Vertebroplasty And Balloon Kyphoplasty, Gladius Lewis, Mark R. Towler, Daniel Boyd, Matthew J. German, Anthony W. Wren, Owen M. Clarkin, Andrew Yates

Chemical and Biochemical Engineering Faculty Research & Creative Works

Vertebroplasty (VP) and balloon kyphoplasty (BKP) are now widely used for treating patients in whom the pain due to vertebral compression fractures is severe and has proved to be refractory to conservative treatment. These procedures involve percutaneous delivery of a bolus of an injectable bone cement either directly to the fractured vertebral body, VB (VP) or to a void created in it by an inflatable bone tamp (BKP). Thus, the cement is a vital component of both procedures. In the vast majority of VPs and BKPs, a poly(methyl methacrylate) (PMMA) bone cement is used. This material has many shortcomings, notably …
