New Collaboration between the Helguera (RIT), Dalecki, and Hocking Labs
A new collaboration, funded by the NIH, brings together the expertise of Professor Maria Helguera (Center for Imaging Sciences, RIT), Professor Diane Dalecki (BME, UR), and Professor Denise Hocking (Pharmacology & Physiology, UR). The collaborative effort focuses on developing novel, ultrasound tissue characterization techniques for engineered tissues. This work is part of a larger project, led by Drs. Dalecki and Hocking and funded by the NIH, that aims to develop ultrasound-based technologies for the field of tissue engineering.
Dr. Helguera's laboratory is devoted to advancing multimodal imaging and materials characterization techniques. Over the years, she has developed a suite of nondestructive, ultrasound-based materials characterization techniques for non-biological materials, such as polymers, ceramics, and layered materials. Through this new collaborative effort, the novel approaches that Dr. Helguera has developed and implemented for ultrasound characterization of non-biological materials will be translated to characterize the biological properties of engineered tissues. We propose to extend and apply high frequency ultrasound-based, tissue characterization techniques to monitor non-invasively biological and structural properties of cells and extracellular matrix proteins within three-dimensional engineered tissues. NIH support for the next two years will allow Dr. Helguera to spend the fall semesters and part of her summers devoted full-time to the research project as a Visiting Scientist in the Dalecki lab at the UR BME department. Drs. Helguera, Dalecki, and Hocking are all members of the Rochester Center for Biomedical Ultrasound.

Marvin Doyley Receives NIH Funding for IVUS Research
Marvin Doyley (ECE) has been awarded a new NIH R01 grant titled
IVUS Detection of Rupture Prone Plaques
. The overall goal of the project is to develop ultrasonic methods to assess the functional and structural properties of life-threatening atherosclerotic plaques and the arterial wall. Dr. Doyley will measure the functional properties of coronary arteries using a prototype intravascular ultrasound (IVUS) system, equipped with a dual frequency IVUS transducer (15 MHz and 30 MHz), to visualize molecules that are expressed preferentially by life-threatening atherosclerotic plaques. Ultrasound contrast agents will be used to target specific blood vessels. The outcome of the project will advance the use of ultrasound for the diagnosis of atherosclerosis. -

Carol Raeman - 20 Years with the RCBU!
This month the RCBU recognizes Carol Raeman's 20 years of employment at the University of Rochester! Carol is currently a Technical Associate I working in the laboratory of Professor Diane Dalecki in the Department of Biomedical Engineering. Carol started her employment with the University in 1989 working with Professor Ed Carstensen in the Department of Electrical Engineering. During her early years of employment, Carol played a key technical role in many studies on the biological effects of lithotripter fields. Only one year after her initial hire, Carol was already a co-author on 5 papers dealing with the bioeffects of lithotripter fields and pulsed ultrasound on the kidney, chick embryo, and lung. As her career progressed, Carol contributed to many significant studies on the effects of ultrasound on tissues containing contrast agents, the mechanisms for ultrasound-induced lung damage, effects of ultrasound on the heart and neural tissue, and the interaction of very low frequency underwater sound with biological tissues. Recent areas of Carol's work include applications of ultrasound in wound healing and cell and tissue engineering.
Carol is highly skilled in both our biological and acoustic techniques, and contributes to the design and completion of a wide variety of research projects in our lab. Her experience, ingenuity, technical ability, and collaborative skills make her an enormously valuable member of our laboratory team. She has made outstanding contributions to the field of biomedical ultrasound over the years and we are very fortunate that she is a member of our lab.

Kelley Garvin Wins Best Student Paper Competition
Kelley Garvin won the Best Student Paper Competition at the 157th Meeting of the Acoustical Society of America held in Portland, OR from May 18-22. Her paper, titled
Ultrasound standing wave fields control the spatial distribution of cells and protein in three-dimensional engineered tissue,
was recognized as the best student paper in the Biomedical Ultrasound / Bioresponse to Vibration Technical Section. Kelley presented her recent work demonstrating the use of ultrasound fields to non-invasively control the spatial locations of cells in collagen-based engineered tissues. Ultrasound standing wave fields were used to organize cells into planar bands within collagen gels, resulting in a significant two-fold increase in cell-mediated gel contraction, suggesting that ultrasound-induced cell organization leads to a differential extracellular matrix remodeling. Further, using ultrasound to spatially band endothelial cells within collagen gels resulted in vessel sprouting. These novel technologies have important applications to the fabrication of engineered tissues with desired tissue characteristics. Kelley is a third year graduate student in the Department of Biomedical Engineering (BME) and her thesis research is co-advised by Dr. Diane Dalecki and Dr. Denise Hocking. Kelley is also a student member of the Rochester Center for Biomedical Ultrasound (RCBU). Kelley's research is part of a larger, multidisciplinary project, led by Drs. Dalecki and Hocking and funded by the NIH, that aims to develop novel ultrasound technologies for the field of tissue engineering. -

Senior Design Students Take on Ultrasound Problem for Final Project
For the last nine years, senior engineering students have helped real-life customers solve biomedical engineering problems through a two-semester Senior Design course taught by Amy Lerner, Ph.D., and Scott Seidman, Ph.D. This year, BME seniors Aaron Gelinne, Bo Wang, Andrew Bochenko, and Tony Broyld solved Dr. Paul Bigeleisen's need for a system to stabilize an ultrasound imaging transducer when inserting a needle into tissue. According to Dr. Lerner,
The UltraNeedle team was a great example of the kind of successful design process our students use to develop medical innovations. The students worked extensively with their clinical 'customer', learning about the technical challenges of the medical setting, and the demands of the end-user. They developed a simple, but elegant prototype that allowed for significant testing by representative customers. At the same time, they thoroughly considered the challenges that may be faced in manufacturing, marketing and obtaining regulatory approval for their device. We are very proud of their success, and look forward to continued development of their proposed solution.
