Amy Van Hove, Brandon Wilson and Danielle Benoit, Ph.D. have published an article entitled, Microwave-assisted Functionalization of Poly(ethylene glycol) and On-resin Peptides for Use in Chain Polymerizations and Hydrogel Formation, in the Journal of Visualized Experiments (Jove). The paper discussed one of the main benefits to using poly(ethylene glycol) (PEG) macromers in hydrogel formation is synthetic versatility. The ability to draw from a large variety of PEG molecular weights and configurations (arm number, arm length, and branching pattern) affords researchers tight control over resulting hydrogel structures and properties, including Young's modulus and mesh size.

Jason Inzana and Dr. Hani Awad
A recent article in Hajim School of Engineering' and Applied Sciences' newsletter, The Full Spectrum, features examples of how tissue engineering research at the Biomedical Engineering Department, much of which is conducted in preclinical models to heal traumatic injuries, is bolstered by the work of BME faculty and graduate students in the laboratories of professors Awad, Benoit, and Buckley, capitalizing on close ties with the Center for Musculoskeletal Research.
As part of a consortium of research projects funded by AOTrauma, Dr. Hani Awad and his lab members are using new 3D printing technology to fabricate bone scaffolds made of biocompatible material to replace the original bone tissue lost to infection. As part of the
printingprocess, the scaffolds can be
ink-jettedwith antibiotics to fight the infection and with growth factors to stimulate replacement bone growth. These therapeutics can be applied to the surface of the graft, or embedded uniformly in it, so they can be released gradually, as the graft dissolves, to ensure the infection is eradicated and to stimulate regeneration of the bone tissue.

Dr. Mark Buckley
With support from a National Institutes of Health grant, Dr. Danielle Benoit's team is exploring the use of hydrogels - Jell-O-like polymers - that can be seeded with the patient's own stem cells and wrapped around the transplant. Benoit's graduate student Michael Hoffman has demonstrated that as the hydrogel dissolves, the stem cells are gradually released and promote bone healing and integration. Benoit is exploring various ways in which this can all be orchestrated to maximize graft healing and integration.
Dr. Mark Buckley, who joined biomedical engineering as an assistant professor at the start of the year, is studying heat buildup in tendons as they are stretched during various activities and the extent to which this contributes to cell death and eventual deterioration of the tendon. A key part of this research involves characterizing exactly what constitutes healthy tendon structure and function.

An estimated 14,380 Americans this year will get the news. They have head and neck cancer. Most will receive carefully calibrated doses of radiation therapy each day over several weeks to kill cancer cells and shrink the tumor. At some point, more than 90 percent will notice an unpleasant parched sensation in their mouths. It is a side effect of the radiation treatment called xerostomia, or dry mouth. For most, the persistent dryness will become a permanent part of their lives, causing difficulty with eating and speaking, oral infections, dental caries, tissue inflammation, and decreased quality of life.
In the June issue of the journal Molecular Therapy, a team of NIDCR-supported scientists report initial success in reducing apoptosis in the submandibular salivary gland in mice. They do so using short interfering RNAs (siRNAs), which are small RNA molecules that can be introduced into a cell to block temporarily the expression of a protein.

BME Undergraduate Awarded Scholarship for 2013-14
BME undergraduate Amanda Chen has been awarded a Tau Beta Pi Scholarship for 2013-14, in the amount of $2,000 for a year of full-time academic study, or $1,000 for a semester or two quarters of full-time academic study. Amanda is currently studying therapeutic biomaterials for treating bone remodeling disorders in Dr. Danielle Benoit's lab. Congratulations Amanda!

The Benoit Lab Lemonade Stand at the Rochester Public Market in 2012
On most days, Danielle Benoit can be found in her lab developing better ways to administer medicines for treating diseases, particularly childhood cancer. This weekend, Benoit and the other researchers in her lab will show their support for the foundation that helps fund their research. They'll put down their beakers and syringes in favor of pitchers of lemonade—in the spirit of the little girl who made it all possible.
The 4th Annual Benoit Laboratory Lemonade Stand takes place this weekend at the Rochester and Brighton public markets. Benoit, assistant professor of biomedical engineering, and her fellow researchers will be serving lemonade and explaining their work on childhood cancer therapies. It's part of a national effort organized by Alex's Lemonade Stand Foundation.
The name comes from Alexandra "Alex" Scott of Connecticut, a four-year-old girl who was diagnosed with cancer before her first birthday. She set up lemonade stands every year before her death at age 8 to raise money so that doctors could find a cure for cancer. The idea spread, and children in other parts of the country set up their own lemonade stands to join the cause.
"Cancer affects children differently than it does adults," said Benoit. "The causes are unknown and the treatments are less-than-optimal since they were developed for adults." Cancer is also the leading cause of death for children 15 and younger.

BME Undergraduates Win President's, Dean's, and Professor's Choice Awards
Ian Marozas, a BME undergraduate in Danielle Benoit's lab, was awarded the President's Award for Undergraduate Research in Engineering and Applied Sciences, this afternoon at the Undergraduate Research Expo for his presentation Development of Targeted Drug Delivery Systems for the Treatment of Osteoporosis. Also, Michael David won the Dean's Award for Undergraduate Research in Engineering & Applied Sciences for his talk Effect of High Fat Diet-Induced Obesity and Type 2 Diabetes on Tendon Repair (Mentor: Dr. Robert Mooney) and Ka Lai Tsang won the Professor's Choice Award in Engineering and Applied Sciences for her poster Determination of Effective masses and parametric study of the organ of corti (Mentor: Jong-Hoon Nam).

Biomedical Engineering (BME) Undergraduate, Amanda Chen ('14) has been selected as a 2013 Goldwater Scholar. Each scholarship covers eligible expenses for undergraduate tuition, fees, books, and room and board, up to a maximum of $7,500 annually. The Barry Goldwater Scholarship and Excellence in Education Program was established by Congress in 1986 to honor Senator Barry M. Goldwater, who served his country for 56 years as a soldier and statesman, including 30 years of service in the U.S. Senate.
The purpose of the Foundation is to provide a continuing source of highly qualified scientists, mathematicians, and engineers by awarding scholarships to college students who intend to pursue careers in these fields. Amanda is currently persuing research in Dr. Danielle Benoit's lab focusing on Therapeutic Biomaterials for Treating Bone Remodeling Disorders. Her future goals include persuing a Ph.D. in BME as well as continuing research in therapeutics and targeted delivery, while teaching at the university level.
