The Department of Biomedical Engineering has written a wonderful article highlighting the Department’s research activity during the summer for which Aissah Kaba and Sherilynn Knight play very active roles.
REU Jacob Norman placed 2nd in the Physical Sciences category. He won for his
research titled Theranostic Polymer Agents for Ultrasound Therapy and Controlled Drug Release. His mentor for the summer was Dr. Eugenia Kharlampieva (Chemistry). Jacob is a sophomore bioengineering student at the University of California Berkeley.
Both participants were supported by National Science Foundation (Grant Number DMR # DMR 1460392) – Research Experiences for Undergraduates (REU) award to UAB
Congratulations Julian and Jacob and all of the other Expo w. Great job.
We are pleased with the tremendous response to our call for applications to our Research Experience for Undergraduates program for summer 2016 here at UAB. Given the hundreds of applications that we received, the competition was quite impressive. The names of our 2016 REU participants will be posted as soon as all offers have been made and accepted.
We thank every applicant for their interest in our program and we hope that all eligible applicants will apply again next year. In the meantime, for those well deserving applicants that applied and were not selected, we are hopeful that many of them were selected to other programs.
Congratulations to 2015 REU Szu Chun Chen for her 1st Place Win in the Undergraduate Poster Category at the 2015 NanoBio Summit at UAB. Szu’s presented a poster titled: Poly(N-vinylcaprolactam) base d Multil ayers for Drug Delivery with Temperature-gated Permeability.
2014 REU Danna Nozik Takes 1st Place at AIChE Conference
Congratulations to 2014 REU Danna Nozik. Danna won first place at the 2014 AIChE (American Institute of Chemical Engineers) poster competition in the category of Materials Engineering and Sciences. We are exremely proud of Danna for such fine job. Below is Danna’s abstract.
ABSTRACT: There is a huge demand for small-diameter vascular grafts, as the majority of vascular disease cases involve small-caliber blood vessels. Recently, electrospinning has gained attention as a valuable technique for the fabrication of scaffolds for blood vessel engineering, as electrospinning produces nanofibers that closely approximate the structure of native extracellular matrix (ECM).
Accordingly, electrospun scaffolds were fabricated in a 3D tubular structure from a blend of the synthetic polymers, viscoelastic and durable polycaprolactone (PCL) and relatively fast-degrading shape memory poliglecaprone (PGC). The scaffolds were coated with a physiological biomatrix, HuBiogelTM. The biohybrid graft was found to exhibit mechanical properties comparable to those of native blood vessels, and the HuBiogelTM coating imparted bioactivity. The coating was crosslinked using EDC and the natural crosslinker genipin (Gp) to improve its stability in physiological conditions. This study evaluated the effects of EDC- and Gp-crosslinking on the scaffold mechanical, structural, and morphological properties. Additionally, coating stability was studied to assure the presence of collagenous biomatrix on the scaffold for effective cell-matrix interactions.
Mechanical testing showed little difference between EDC- and Gp-crosslinked scaffolds; both retained mechanical properties in the range of native human arteries (tensile strength 1-2 MPa, tensile modulus 9-12 MPa). SEM imaging revealed that while crosslinking with EDC resulted in an increase in fiber diameter compared to uncrosslinked scaffolds, Gp-crosslinking did not affect fiber diameter; the majority of fibers in EDC and Gp-crosslinked scaffolds had diameters ranging from approximately 0.9 – 1.4 microns and 0.7 – 1.2 microns, respectively. This is in the upper range of fiber diameters in native extracellular matrix. Coating stability studies using picrosirius red (PSR) stain showed that EDC-crosslinked scaffolds were more effective than Gp-crosslinked scaffolds in enhancing the stability of the biomatrix coating.
Larry Lawal entered the Alabama Launchpad Competition
Larry Lawal entered the Alabama Launchpad startup business competition and out of 27 contestants, he made the cut to the Top 10. The Top 10 will be considered for prizes totaling $100,000. Per al.com, “Healthfundit: is the only peer-reviewed, subscription-based crowd funding portal for health research and biotechnology at academic institutions. Team leader is Larry Lawal. Based in Birmingham.”
Each contestant will present their plans to a panel of judges on July 12, 2013. We wish Larry good luck and we’re certainly proud of this accomplishment.
Crowdfunding Panel Discussion
On June 13, 2013, Larry served on a panel to discuss “Crowd-funding” which is essentially a network of people that pool their money together to support the ventures of members of the network. Larry was idea for this panel given his recent startup: Healthfundit. We wish Larry continued success in his efforts to develop and grow his business.
2012: Congratulations to Taoreed “Larry” Lawal for being the recipient of the 2012 Minority Scholar in Cancer Research Award. Larry continues to impress with his diligence in seeking opportunities that will serve the research community well.
HealthFundit website will not launch until November 2013, but you can “like” it Facebook and follow on Twitter.
Aditi Naik, a participant in our 2012 REU program, has been invited by the Harvard College Undergraduate Research Association to attend the National Collegiate Research Conference 2013. The conference will be held January 24-26, 2013 at Harvard University. Aditi was selected from a pool of approximately 400 applicants. The conference’s overall mission is one of promoting interdisciplinary research among Harvard undergraduates. The NCRC’s expanded reach offers students like Aditi tremendous opportunities to network with peers, educators and industry professionals. Aditi will showcase her REU research by presenting a poster and I am sure she’ll be a shining example for the REU program.
Each summer, the REU program culminates with the participants presenting their research posters in a campus wide expo. The Expo categories are Life Sciences (I,II,III), Physical Sciences and Engineering (I, II) and Public Health and Social and Behavioral Sciences (I, II). Because of the large number of participants in the Expo, all three categories are divided into multiple groups for judging purposes. Our REU participants presented posters in the Life Sciences and Physical Sciences and Engineering categories.
The posters are judged by volunteer faculty and postdocs according to their backgrounds. Awards are given to 1st, 2nd and 3rd place winners in each category as well as honorable mentions. Below are our 2012 Summer Research Expo Winners:
UAB-REU Participant Larry Lawal is named Barry M. Goldwater Scholar for the Academic Year 2008-2009
