Dr. Eugenia Kharlampieva Awarded a National Science Foundation Biomaterials Grant Immunomodulatory Ultrathin Multilayer Coatings for Pancreatic islet Transplantation NSF-DMR1306110, program of Biomaterials (BMAT)
This grant will supports the development of a novel type of cytoprotective material with controlled immunomodulatory and inflammatory responses to be used for cell-basedtransplantation therapy for diabetic recipients. This project is in collaboration between departments of Chemistry (Eugenia Kharlampieva, PI) and Microbiology (Hubert Tse, coPI). Although transplantation of pancreatic islet cells has emerged as a promising treatment for Type 1 diabetes, its clinical application remains limited due to adverse effects of immunosuppression and declining allograft function. The awarded project will develop a preclinical approach to preserve islet viability and function during culturing and transplantation by protecting pancreatic islets (cell clusters) with a novel polymer coating. These coatings will be designed through hydrogen-bonded assembly of cytocompatible macromolecules with antioxidant and anti-inflammatory characteristics. This project is particularly timely since current islet encapsulation systems are challenging for transplantations due to high cytotoxicity and the requirement for large injection volumes. The design of novel immunoprotective materials will open new prospects for developing biomaterials with unique characteristics having applications in various bio-related areas such as bioengineering and tissue engineering. The awarded project will develop interdisciplinary collaborative research which should stimulate awareness of the needs of the UAB biomedical research community for specialized polymer-based biomaterials as novel platforms for cell transplantation therapy.

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:
NIH Issues a Small Business Technology Transfer Phase II Award to Vista Engineering and UAB CNMB Scientists
National Institute of Dental and Craniofacial Research (NIDCR) has issued a two-year commercialization award entitled “Nanotechnology Enabled Temporomandibular Joint (TMJ) Prosthesis” to a Birmingham based company Vista Engineering and UAB CNMB researchers (Vista PI Dr. Raymond Thompson and UAB PI Dr. Yogesh Vohra, Dr. Aaron Catledge, and Dr. Patrick Louis).
This award of $746,369 is for a two-year period starting August 15th, 2011. It is estimated that over 10 million people in the United States experience pain and dysfunction in and near the TMJ. Typical symptoms include facial and jaw joint pain, neck and shoulder pain, headaches, locking of the jaw, and limited opening or inability to open the mouth comfortably. The vast majority of these patients can be treated with conservative, non-invasive therapies. However, some patients with severe TMJ degeneration may require a prosthetic replacement. Implants have been used primarily to replace the articular disc of the joint and the condylar head of the mandible. However, long-term success and functioning of these implants remains a serious problem.
Major factors contributing to the failure of TMJ devices include the choice of the design and materials of the implant, and the production of wear particles that can trigger a cascade of events that ultimately may result in the damage to TMJ structures. CNMB scientists and Vista engineering have been exploring the use of nanostructured diamond coatings on metallic components of TMJ to lower mechanical wear and improve clinical outcomes. The goal of this STTR Phase II program is to design a minimally invasive diamond-on-diamond articulating TMJ device using computational modeling approaches. This next generation of TMJ device will be fabricated and tested in a TMJ wear-simulator to have a service lifetime of more than ten-years of clinical use. The TMJ devices that show lowest mechanical wear in simulator studies will also be tested in an animal model. The clinical translational studies are planned to eventually allow testing of new TMJ devices for human use in the next few years.

The imaging microprobe X-ray photoelectron spectroscopy (XPS) system is designed for spatially resolved chemical analysis of solid surfaces. This tool creates a new multi-user element of the core shared analytical facility in the interdisciplinary Center for Nanoscale Materials and Biointegration (CNMB) at U of Alabama at Birmingham (UAB). It serves a large team of users from CNMB, four UAB science and engineering departments, and fosters collaborations through the partnership with Alabama State U (ASU) and NSF-Materials World Network with Technical U of Lodz (Poland). XPS is critical for us due to its unique ability to discriminate between different oxidation states and chemical environments in a thin layer (<5 nm) of a material, yet capable of the depth profiling of chemical composition when using a sputtering accessory. Imaging XPS is the only tool that has a combination of features to address the challenges of microscale characterization in our projects on: (i) surface modification and functionalization of new multi-scale biomaterials; (ii) bio-active monolayers and self-assembled biomimetic
Imaging XPS is the only tool that has a combination of features to address the challenges of microscale characterization in our projects on: (i) surface modification and functionalization of new multi-scale biomaterials; (ii) bio-active monolayers and self-assembled biomimetic nanoarchitectures; (iii) novel phases formed under extreme pressures; (iv) chemistry of interfaces and thermally-induced processes in polymer and polymer-ceramic multifunctional nanocomposites; (v) surface and interface phenomena in wide band-gap semiconductor materials and structures; and (vi) nanostructured, multilayer, and gradient metal-ceramic and ceramic thin-film materials. This XPS system provides training in 3 graduate and 5 undergraduate courses with enrollment of ~135 per semester, enhances research opportunities in our interdisciplinary NSF-REU site where women and minorities account for 57% of the participants and in our partner ASU?s CREST and HBCUUP programs, and raises the awareness of surface science and engineering among K-12 students, teachers, and general public through our NSF-RET site and UAB day at McWane Science Center in Birmingham. CNMB provides necessary infrastructure and long-term support for the XPS system operation, accommodation of multiple users, and the initiation of new projects at local, national, and international levels.
