Purification of DNA for Gene Therapy and Vaccines – New Opportunities for Membrane Technology

 

Abstract

There is growing interest in using DNA for gene therapy and DNA-based vaccines.  Existing methods for DNA purification are inadequate for large-scale commercial production.  This talk examines the possibility of using membrane ultrafiltration for the purification of supercoiled plasmid DNA.  DNA transmission during ultrafiltration is a strong function of filtrate flux due to flow-induced elongation of the plasmid associated with the converging flow into the membrane pores.  Transmission of the open circular DNA was significantly less than that of the supercoiled plasmid, while transmission of the linear DNA was considerably enhanced due to differences in conformational flexibility.  New opportunities for enhancing DNA purification were identified using backpulsing to reduce fouling and using novel membranes with controlled pore morphology to pre-stretch the DNA in the elongation flow.  The results clearly demonstrate the potential of using membrane systems for commercial-scale purification of DNA.

Colloquium – Lisa Everett(University of Wisconsin) Physics Beyond the Standard Model in the LHC Era

Tuesday, April 11, 2017 – 4:00pm to 5:00pm
1080 Physics Research Building – Smith Seminar Room – reception at 3:45pm in the Atrium

Particle physics has entered an exciting and data-rich era in which the physics of the Tera-electron volt scale is being probed at an unprecedented level at the Large Hadron Collider.  To date, this exploration has shown the continued triumph of the Standard Model of particle physics in providing a spectacularly successful description of nature — and as such, has placed new facets on the issue of how the Standard Model can be extended to a more complete, fundamental theory.  In this talk, I will provide an overview of the current status of the LHC results and their implications for physics beyond the Standard Model, with an emphasis on the issue of Higgs sector naturalness.

Please join us for an engaging conversation focused on the commercialization of academic research. Learn from health care innovators who took the journey from academic research to successful commercialization and founded their own company along the way. Speakers include Dr. Kathy Bowles, PhD, RN, of the University of Pennsylvania, and Eric Heil, CEO, co-founders of RightCare Solutions, a pioneering medical technology company. Heil developed Dr. Bowles’ research into software while an engineering major at the University of Pennsylvania as part of his senior project, and commercialized it as a graduate student at Wharton School of Business. NaviHealth, a subsidiary of Cardinal Health, acquired this software last year. Kevin Taylor, VP Product Management, Global Market Development at Cardinal Health, will also speak.

“Multi-scale Framework for Analysis of Tricuspid Valve Biomechanics “

Mechanics plays a critical role in tissue development, regeneration, and remodeling, as cell-cell interactions and cellmatrix interactions are known to be heavily influenced by changes in the mechanical microenvironment at the extracellular matrix (ECM)/cellular level. In the tricuspid valve (TV), located between the right ventricle and the right atrium in the heart, the leaflets open and close more than three billion times during their lifetime. Thus, TV cells and ECM maintain their homeostasis while subjected to a highly dynamic loading environment. Considering the hierarchy of the living system (i.e. heart, valves, leaflets, and ECM/cellular levels in the case of TV), it is imperative to study biomechanics and mechanobiology using multi-scale approaches. Unfortunately, such multi-scale frameworks do not currently exist, and a main goal of our research lab is to combine experimental techniques and computational simulation to address such major limitations. We are particularly interested in understanding why TV surgery has poor long-term success rate (30% to 40% of patients who undergo surgery have had a recurrence of valve problems). We aim to understand how tricuspid valve repair procedures will affect the valve’s function at the tissue level and at the ECM (micro) level, as we believe that surgical alterations cause changes in tissue stress and tissue microstructure in ways that can eventually lead to failure of the repaired valve.

 

Bio:

Dr. Amini completed a Ph.D. in Biomedical Engineering at the University of Minnesota in the field of ocular biomechanics and biotransport in 2010. He then continued his research work on the mechanics of soft tissue as a postdoctoral trainee at the University of Pittsburgh’s Department of Bioengineering, where he held the Ruth L. Kirschstein National Research Service Award (NIH F32). He conducted his postdoctoral research on the biomechanics of cardiac valves. Dr. Amini has served as an assistant professor in the Department of Biomedical Engineering at The University of Akron since August 2013. The overall goal of his research laboratory is to improve human health by studying the multi-scale biomechanics and biotransport in cardiovascular, ocular, and digestive systems. Dr. Amini’s research has been funded by the Akron Children’s Hospital, Firestone Foundation, and American Heart Association.
