Tulane Courses Inspire Entrepreneur November 23, 2010

ben-cappiello-entrepreneurWhen Ben Cappiello ’10 was a Senior, he enrolled in Prof. Sergey Shevkoplyas’ course BMEN6760 “Biomedical Microdevices” as an elective. A course requirement was to write a 2-page grant proposal to the Bill & Melinda Gates Foundation, in response to round 4 of their Grand Challenges in Global Health initiative. Ben’s proposal was for an improvement in the instrument that’s used to insert IUD contraceptive implants. The current technology requires four different instruments and a skilled practitioner, and Ben’s design, inspired by what he learned in the course, called for a single instrument that a local health worker could learn to safely use.

The next semester, in Prof. Ed Karp’s SCEN6000 “Engineering Entrepreneurship” course, Ben developed a business plan and a marketing strategy. When he graduated, he knew that he would be an entrepreneur. He and business partner Shuchi Khurana created a start-up venture, Bioceptive LLC (http://bioceptive.com) that's headquartered in New Orleans.

Right now, he divides his time between business development and designing prototypes for the first phase of product trials. The team is writing a SBIR Phase I proposal to the National Institutes of Health, and hopes to start prototype production in early 2011.

 

Shevkoplyas Receives Prestigious Grant to Study
Red Blood Cell Deterioration November 17, 2010

shevkoplyasDr. Sergey Shevkoplyas, Assistant Professor of Biomedical Engineering, has just been awarded a $74,900 grant by the National Blood Foundation. The Foundation only awarded 8 new grants this year.

The quality of red blood cells in storage can deteriorate as the cells lose certain functional abilities and accumulate oxidative damage over time. This "storage lesion" decreases the ability of red blood cells to deliver oxygen effectively in the transfusion recipient.

With the NBF grant "The Relationship between the Ability of Stored Red Blood Cells to Perfuse Microvascular Networks and their 24-hr Post-Transfusion Recovery in Vivo", Shevkoplyas and colleagues will assess the ability of artificial microvasculature networks, or AMVNs, to detect the deterioration in red blood cells that takes place over time. They plan to compare the behavior of stored red blood cells in AMVNs with the 24-hour in vivo recovery of transfused blood in human subjects.

A Leader in Vascular Bioengineering Research September 28, 2010

vascular-bio-researchWith the recent hire of junior faculty members in the areas of angiogenesis (Dr. Lee Murfee), leukocyte mechanics (Dr. Damir Khismatullin), microfluidic devices (Dr. Sergey Shevkoplyas), and stem cell mechanobiology (Dr. Taby Ahsan), Tulane’s Department of Biomedical Engineering is positioned to be a leader in vascular bioengineering research. Design of therapies for some of today’s most challenging biomedical related diseases, such as tumor metastasis, atherosclerosis, cardiac infarction and hypertension, will require an interdisciplinary approach to understanding how we can manipulate the microcirculation. Integration of ongoing research on the directing stem cell differentiation into vascular cells via mechanic cues, cell recruitment to sites of inflammation, and the growth of functional vessels will offer new paradigms for future microvascular research. More importantly, the combination of the computational, in vitro, and in vivo experimental expertise within the Department of Biomedical Engineering Department has established a unique environment at Tulane for vascular research.

 

Dr. Moore Awarded Funding
For Nerve Regeneration Research September 21, 2010

nerve-regenerationDr. Moore recently received funding from the Louisiana Board of Regents (LEQSF[2009-10]-RD-A-18) to further develop techniques he has invented for creating 3D tissue-engineered models of nerve growth. His approach involves a digital micromirror device (DMD), the same technology used in DLP televisions and projectors, for patterning biocompatible hydrogels on the scale of micrometers (1/1000th of a millimeter).These micropatterned hydrogels provide a three-dimensional environment for studying the guidance of neural tissue growth. The National Institute of Neurological Disorders and Stroke awarded funding (R21-NS065374) to use these 3D micropatterned environments for studying the guidance of neural tissue growth in response to biomolecules engineered into the gels. Dr. Moore is specifically interested in a class of biomolecules partially responsible for the development of the optic chiasm, the point at which nerves from both eyes cross to take information from each eye to either side of the brain. The research may lead to a better understanding of how to engineer nerve growth in preferred directions in a manner that more closely resembles natural processes.

 

A Breath of Fresh Air September 14, 2010

a-breath-of-fresh-airRecent NIH-funded investigations aim to identify biological transport properties that can be used to deliver air to obstructed regions of the lung. These studies are particularly relevant to the treatment of acute respiratory distress syndrome (ARDS), which afflicts approximately 200,000 individuals annually in the U.S. and has a mortality rate of 40%. Tulane’s investigations are targeted at the development of mechanical ventilation strategies to reduce the mechanical stress associated with ventilator-induced lung injury (VILI). These studies, performed in the Professor Donald Gaver’s laboratory, use computational modeling, micro-scale flow visualization techniques and biological assays to identify surfactant transport interactions that may reduce the deleterious mechanical stresses that can damage sensitive pulmonary epithelial cells. These studies test the hypothesis that engineered pulsatile ventilation waveforms will minimize damage to airway epithelial cells by optimizing surfactant transport and biophysical responses to reduce the damaging mechanical stresses imparted on the airway epithelium.
