Mark Buckley receives grant from AOFAS

August 2, 2016

vvBiomedical Engineering Professor Mark Buckley received a grant from the American Orthopaedic Foot & Ankle Society (AOFAS) for his research project entitled, "In Vitro Assessment of the Role of Mechanical Strain in the Pathogenesis and Reversal of Insertional Achilles Tendinopathy." Insertional Achilles tendinopathy (IAT) is a common and painful disorder that responds poorly to conservative (i.e., nonoperative) care. Improved outcomes for IAT patients require interventions that target the fundamental causes of the disease. Thus, this study seeks to elucidate 1) how mechanical deformations occurring in the Achilles tendon insertion can lead to IAT pathogenesis (using an in vitro model); and 2) whether the IAT-associated changes can be reversed in vitro by specific mechanical loading regimens. The findings of this study will motivate effective, targeted non-surgical therapies for IAT.


Steve McAleavey receives NIH R21 grant

July 28, 2016

dStephen McAleavey, associate professor of biomedical engineering, has received a $408,368 R21 grant from the National Institutes of Health for his project, "Quantification of Shear Wave Strain Dependence in Breast Tissues.” Many women presently undergo breast biopsy due to lesions detected with x-ray and ultrasound imaging. The great majority of these biopsies are negative, resulting in needless expense and worry. The goal of this project is to improve the power of ultrasound imaging to predict if a breast lesion is benign or malignant, by using a novel, high-resolution technique to non-invasively map the non-linear mechanical properties of breast tissue. These properties are determined by the microstructure of the tissue and show marked differences between benign and malignant tissues. Stephen’s co-investigators on this interdisciplinary project are Marvin Doyley, associate professor of electrical and computer engineering; Linda M. Schiffhauer, associate professor of pathology and laboratory medicine, and Avice O’Connell, professor of imaging sciences.

New patent issued for Professor Hocking

September 3, 2015

The patent titled “Chimeric Fibronectin Matrix Mimetics and Uses Thereof” (US 9,072,706) has recently been assigned to the University of Rochester with inventors Denise Hocking, Ph.D. (Pharmacology and PhysiologyBMERCBU) and Daniel Roy, Ph.D. (BME PhD 2012 alumnus). The patent relates to a series of recombinant fibronectin peptide mimetics developed to promote wound repair. The technology falls under a new and exciting class of therapies known as wound biologics. The primary commercial application for this technology is to promote healing of hard-to-heal or chronic wounds, including diabetic, venous, and pressure ulcers, which impose a significant health care burden worldwide. Encouraging results from recent studies indicate that topical application of these fibronectin peptide mimetics to full-thickness excisional wounds in diabetic mice accelerates wound closure and promotes granulation tissue deposition, remodeling, and re-vascularization. Denise Hocking is an Associate Professor of Pharmacolog and physiology and of Biomedical Engineering. Daniel Roy is currently a post-doctoral fellow at the US Army Institute of Surgical Research in San Antonio, TX.

Professors Dalecki and Hocking Research Wins Best Paper Award at SPIE-DSS

May 6, 2015

The latest research by Professor Diane Dalecki (BMERCBU) and Professor Denise C. Hocking (Pharmacology & PhysiologyBMERCBU) was recognized with the Best Paper Award at the Micro- and Nanotechnology Sensors, Systems, and Applications Conference of the SPIE Defense + Security Symposium held recently in Baltimore, Maryland. Their invited paper titled “Guiding Tissue Regeneration with Ultrasound In Vitro and In Vivo” detailed three biomedical ultrasound technologies under development in their laboratories to stimulate tissue formation and regeneration. Co-authors of the paper included Sally Child, Carol Raeman, and BME graduate students Eric Comeau and Laura Hobbs. One technology under development employs forces within an ultrasound standing wave field to provide a noninvasive approach to spatially pattern endothelial cells and thereby guide the development of complex microvessel networks. A second technology uses ultrasound to site-specifically control the microstructure of collagen fibers within engineered hydrogels to direct cell function. The third line of research focuses on developing ultrasound as a therapeutic approach to enhance tissue regeneration in chronic wounds. These ultrasound technologies offer new solutions to key challenges currently facing the fields of tissue engineering, biomaterials fabrication, and regenerative medicine.

Remembering Ultrasound Pioneer Floyd Dunn

February 1, 2015

floydThe biomedical ultrasound community sadly lost one of its important pioneers. Floyd Dunn passed away on January 24, 2015 at the age of 90. Floyd was a member of the Electrical and Computer Engineering Department at the University of Illinois at UrbanaChampaign for over 50 years. Following the death of Bill Fry in 1968, Floyd became director of the Department’s Bioacoustics Research Laboratory and made it a world leader in the field of biomedical ultrasound. Founding RCBU Director Ed Carstensen writes, “It is hard to believe today, but in the mid-1960s, research in this field had dwindled to the point that progress could be reported in biannual sessions at meetings of the Acoustical Society. Floyd and Wesley Nyborg organized those special sessions and we are uniquely indebted to them for keeping the field alive.” Floyd’s body of scientific work provides foundation for our understanding of the propagation of ultrasound in tissues and the biological effects of ultrasound. He was a member of both the National Academy of Sciences and the National Academy of Engineering, and served as President of the Acoustical Society America. He was recognized with the highest awards from numerous scientific societies, including the IEEE Edison Award, the ASA Gold and Silver Medal Awards, and the AIUM Joseph P. Holmes Basic Science Pioneer Award. He served on many FDA, NIH, AIUM, and ASA committees, and was a member of Committee 66 of the National Council on Radiation Protection. Floyd was a Charter Honorary Member of the RCBU and was a long-time friend and colleague for many of us. The RCBU and the wider biomedical ultrasound community will miss Floyd dearly.


New Study Probes Link Between HIV Drugs and Vascular Disease

January 13, 2015

RCBU Faculty member Marvin Doyley, Ph.D., is a part of a multidisciplinary team that was recently awarded a $3.8 million grant from the National Institutes of Health to better understand why individuals who receive anti-retroviral treatment for HIV are at greater risk for heart disease and stroke.


Associate Professor Marvin M. Doyley part of multidisciplinary team awarded $3.8 million NIH grant

January 6, 2015

Marvin M. Doyley, Associate Professor of Electrical and Computer Engineering, is part of a multidisciplinary team which was recently awarded a new $3.8 million grant from the National Institutes of Health to better understand why individuals who receive anti-retroviral treatment for HIV are at greater risk for heart disease and stroke. Scientists speculate that this occurs due to some combination of the infection and treatments themselves, which may be damaging cells in the body’s blood vessels.  One of the key measures in the study will be the thickness and stiffness of the carotid artery – the major blood vessel that serves the head and brain. The researchers will employ a new ultrasound technology developed by Prof. Doyley’s group to track changes to the vessel over time. UR neurologist Giovanni Schifitto is one of the principal investigators of the study, along with Sanjay Maggirwar, (UR Department of Microbiology and Immunology) and Jun-Ichi Abe (M.D. Anderson Cancer Center in Texas). Vikram Dogra (UR Imaging Sciences), Amneris Luque (UR Infections Disease Unit), and Xing Qiu (UR Biostatistics and Computational Biology) are also members of the research team. Congratulations to Prof. Doyley and the entire team!
