IN THIS ISSUE
On the cover:
Heart disease is the No. 1 killer of men and women across the globe, according to the World Health Organization. UC Irvine biomedical engineering researchers are creating a hybrid tissue-engineered heart valve that may expand options for cardiac surgery patients.
BME Discovery is published once a year in the fall by the Biomedical Engineering Department, UC Irvine Samueli School of Engineering. Chair: Abraham Lee Department Administrator: Cathy H. Ta Business Office Analyst: Julio Rodriguez Established in 2002, the UCI Biomedical Engineering Department offers two undergraduate degree programs, M.S. and Ph.D. degrees in biomedical engineering, and a combined M.D./Ph.D. degree in conjunction with the UCI School of Medicine. There are currently 22 full-time faculty and 59 affiliated faculty. Research areas include micro/nano medicine, biophotonics, biocomputation and tissue engineering, with clinical emphases in neuroscience, cardiovascular diseases, cancer and ophthalmology.

From the Chair establishing global partnerships, facilitating entrepreneurship, increasing student/faculty recruitment and advancing interaction with the community in which we live.
We live in an exciting time in the history of technological advances. I believe people today are more conscientious about their personal health and well-being due to the explosion of accessible information at their fingertips. More and more, we pay attention to our health indicators – blood pressure, blood sugar, heart rate variability, sleep/deep sleep and BMI – at an earlier age. Information soon will be available in real time with dynamic access, thanks to the development of the Internet of Things. This phenomenon is going to democratize our awareness of the predictive power of molecular (e.g. DNA, protein) markers and the preventive power of healthy lifestyles, nutrition and exercise. People are taking their healthcare into their own hands, constantly seeking gadgets, apps and bio- and physiological sensors to help them understand where they stand on the scale of healthy living. I like to think of it as the era of “personal biomedical engineering,” and together, we “BMEers” have tremendous opportunities and responsibilities to increase access to the wealth of health technologies. As one of the presidential candidates stated in a recent debate, doctors treat the things that make people who they are. Skin or hair color doesn’t make a person. The biomedical engineering field, in particular, should embrace this spirit, and harness talent and creative insights from diverse backgrounds. In the next few years, I will work hard to bring diversity to BME at UCI in many dimensions, through
Over the past six months, we have notched several important accolades. One of our students won the Schlumberger Faculty of the Future Award, a recognition intended to encourage female graduate students from developing countries to carry out research pertinent to the needs of their home country, and eventually return to impact education and technological infrastructure. Additionally, former students are starting companies to commercialize biomedical devices and apps, a trend that is burning like wildfire through our department. The BioENGINE program led by Associate Professor Michelle Khine is spearheading this effort; I will highlight the activities and vision of BioENGINE in a future BME Discovery issue. Another outstanding student, Li Xiao, won the Lambert Prize, which is awarded every other year for the best paper submitted by a UCI graduate student, in any school or department, addressing issues in natural or social sciences. Faculty accolades include the Beckman Foundation Young Investigator’s Award, won by Assistant Professor Chang Liu, and the Innovator of the Year Award won by Associate Professor Elliot Botvinick. Our faculty continues to garner large grants and awards, providing the resources to lead the next generation of BME cutting-edge research. Liu is a model representative of this cohort, having been awarded five grants/awards in the last six months. I am proud of all these accomplishments and am honored to be part of this young and talented department.

Hybrid Heart Novel technology creates patient-specific valve that won’t degrade over time Current valve replacement options are limited to those made solely from manufactured products (mechanical valves) or animal tissue (bioprosthetic valves). Mechanical heart valves tend to last longer than bioprosthetic valves, but they carry a greater long-term risk for blood clots that may lead to stroke and arterial thrombosis (clotting in the arteries), as well as bleeding from anticoagulant medications designed to prevent thrombosis. “Bioprosthetic valve replacements, on the other hand, are prone to limited durability, which means patients may need a reoperation usually 10 to 15 years after implantation,” said Alavi. Traditionally, tissue-engineered valves are built on a scaffold that will degrade once the tissue is more mature. Once the scaffold has degraded, however, the valve leaflets often shrink, which can cause leaks and result in valve failure. UC Irvine BME researchers have created a new heart valve that combines a patient’s own cells with metal alloy for a more durable replacement with potentially fewer complications. They published their research in the June 2015 issue of The Annals of Thoracic Surgery. BME postdoctoral scholar S. Hamed Alavi and Associate Professor Arash Kheradvar, M.D., developed the potentially revolutionary hybrid tissue-engineered heart valve.
“For our research, we decided to use a non-degradable scaffold that stays within the valve to provide the support it needs without interfering with its normal function,” said Kheradvar. “The valve we created uses an ultra-flexible scaffold made of an alloy of nickel and titanium (nitinol) that is enclosed within the patient’s own cultured tissue. The entire process takes about three to eight weeks.” The researchers said they expect the hybrid valve to regenerate inside the body, eventually incorporating itself into the patient’s heart structure. By using the patient’s own cells, the valve will become a “living” replacement for the diseased valve.
Building a Personalized Heart Valve Research project uses cells from the patient’s own body to help create a hybrid heart valve.

“We believe this new hybrid technology will significantly improve a patient’s quality of life by eliminating the need for lifelong medications and without compromising the durability of the valve,” said Alavi. “This is particularly beneficial for younger patients who are in need of a heart valve replacement.”
The researchers have completed initial lab testing and now plan to initiate the next phase of trials. If all goes well, they anticipate the hybrid heart valve will be available for use in patients in five to 10 years. The Society of Thoracic Surgeons

Promising Pathways National Cancer Institute Funds Cancer Cell Project
A national team of scientists, led by Samueli School Professor Peter Burke, is using nanofluidics to peer into the life-and-death cycle of cancer cells, hoping the information will one day lead to personalized treatment protocols and the development of more effective, cell-targeted pharmaceuticals. Burke, professor of electrical engineering and computer science, who is an affiliate faculty member in biomedical engineering, along with researchers from Harvard and the University of Pennsylvania recently were awarded nearly $1.2 million from the National Cancer Institute. The grant is funded through the NCIâ€™s Innovative Molecular Analysis Technologies program, which supports the development, technical maturation and dissemination of potentially transformative next-generation technologies in cancer
research. The collaborators seek to map out pathways of the molecular process in cancer cells. At the heart of the research is a nanofluidic chip, which can manipulate and probe single mitochondrion from healthy and cancer cells, allowing them to be tested with libraries of proteins and chemicals â€“ both natural and manufactured â€“ to learn more about why cancer cells respond to signals differently than non-cancerous cells. Researchers will
measure the cell life-death decision-making process, using a variety of methods including nanosensors capable of measuring mitochondrial electrical energy. The mitochondria, often known as the cell’s power plants, metabolize sugar to create energy; this energy is stored as a voltage across their surface. But mitochondria have a secondary role: they regulate the cell-death pathway. Normal cells react to stress by undergoing a process called apoptosis – programmed cell death. In response to certain triggers, the mitochondria form a pore or pores on their surface, spilling out a signaling protein that prompts the cell to self-destruct. When a cell dies, the voltage from the mitochondria shuts down as well. But cancer cells express an abundance of BCL2, a protein that keeps these apoptotic functions suppressed. By subjecting mitochondria from cancerous tissue to different combinations and concentrations of chemotherapy drugs and manufactured and natural proteins, researchers hope to learn which unique combinations can overpower the effect of BCL2 cell proteins on apoptosis and force mitochondria to form the pores that lead to cell death. “Here is the question we’re trying to answer: Why don’t cancer cells die and how does chemotherapy work?” Burke says. “Cancer cells are resistant to the signals that cause them to die. Understanding that process is very important in understanding cancer.” Researchers do know that two people with the same cancer often react differently to the exact same treatment. Similar tumors can have different properties, causing some cells to depolarize (die) more easily than others. This lab-on-a-chip technology could one day lead to advances in personalized medicine, using test results from specific tumors to create individualized treatment plans, “because not only are people different, but tumors themselves are different,” Burke says. Current cancer treatment has another well-known drawback; chemotherapy drugs routinely kill healthy cells along with tumors. “This [technology] could help us figure out a way to cause the cancer cells to commit suicide without causing the same reaction in other cells,” says Burke.
Current tumor profiling is still rudimentary; it requires tens of thousands of cells to obtain a small amount of information. The chip being developed in Burke’s lab will have the capability to test single cells or mitochondrion, allowing researchers to get a lot more information from tissue samples much more quickly. According to Burke, a 10,000-cell assay on the chip could yield up to 1 million times more information than current techniques. “We’re going to make that assay thousands of times more powerful by testing not just one or two drugs at a time but thousands of different combinations of drugs or different concentrations.”
“Cancer cells are resistant to the signals that cause them to die. Understanding that process is very important in understanding cancer.”
Researchers also are hoping to develop on-chip technology that will allow them to understand the biophysical mechanisms that create the formation of the mitochondrial pores. Scientists aren’t sure exactly how the pores form, what their electrical properties are and whether mitochondria produce one pore or multiple pores during apoptosis. “If we can figure out what is causing the mitochondria to depolarize, we will have a better understanding of why the cancer cell lives or dies,” Burke says. “The technology will help us start asking questions about these metabolic pathways and start answering the questions of why cancer cells don’t die.” Collaborators on the project include Anthony Letai from Harvard University and Douglas Wallace from University of Pennsylvania. Anna Lynn Spitzer
The tiny chip, currently in development, ultimately will contain thousands of half-micronwide channels, allowing high-throughput testing. (One-half a micron is 500 nanometers, less than 1/100 the width of a human hair.)
Faculty Accolades Chang Liu Receives Research Acclaim and Funding Awards BME Assistant Professor Chang Liu recently accumulated two prestigious accolades and two research grants. Liu was named both a Beckman Young Investigator and a DuPont Young Professor. He was one of just eight 2015 Beckman Young Investigators spanning physics, chemistry, biology, bioengineering and electrical engineering selected nationwide. Each awardee receives $750,000 over four years in support of his/her research. The Beckman Young Investigator program provides research support to the most promising early-stage young faculty members in the chemical and life sciences, specifically those fostering new methods, instruments and materials that will open up new avenues of scientific research. The 2015 DuPont Young Professors comprise nine researchers on four continents; each receives $50,000 during the next two years to support research that advances basic science addressing global challenges in food, energy and protection. “I am thrilled to receive both of these honors,” he added. “It is recognition of the creativity and dedication of my research group and welcome (and well-funded) support to help turn our ambitious ideas into reality. I am humbled to be a part of both programs, which have supported many of my favorite scientists.” Liu also garnered two recent funding awards for his research. He works to engineer synthetic genetic systems that go beyond the capabilities of natural systems. These “orthogonal” genetic systems can accelerate the speed of evolution and reinterpret genetic code, for example. The work can advance the discovery and production of cancer drugs and useful
enzymes; it also can allow cells to be turned into “polymer synthesis factories,” for evolving new antibiotics and other materials. His lab received a $580,000 grant from NSF to develop orthogonal DNA replication for XNA incorporation, and it will be the U.S. member of an international consortium aimed at developing XNA biosystems in vivo. And DARPA granted him $560,000 for a project aimed at slowing down evolution using orthogonal DNA replication. “At the more fundamental level, our excitement over orthogonal genetic systems is that they may provide the platform for synthesizing life from the ground up,” said Liu.

TinyKicks is developing a wearable health-monitoring smart sensor that captures fetal movement and uses machine learning to predict and guide healthy pregnancy outcomes. The sensor, similar in size to a Band-Aid, consists of a conformal strain sensor and a wireless Bluetooth module to send data to the mother’s smartphone.
Student Highlights Graduate Student Receives Future Faculty Award
Two Grad Students Publish Research Findings
BME doctoral student Neha Garg received the Schlumberger Foundation Future Faculty award. This award supports outstanding women from developing countries with up to $50,000 a year in their pursuit of doctoral or postgraduate STEM studies. Winners are chosen based on leadership qualities, academic performance, outstanding references, research relevance and engagement toward science and education as a development tool in their home countries.
Science Advances published Xiang Li’s work on heterologous expression of sulfated peptides, as part of an effort to identify an activator of an important innate immune receptor in plants. This project is led by the Ronald Lab at UC Davis, which seeks to help collaborators pursue further studies of sulfated peptides in plant immunity and to develop sulfated peptides as therapeutic reagents for plants and animals.
Garg works on the separation and enrichment of circulating tumor cells (CTCs) using acoustics in a microfluidic device, called a lateral cavity acoustic transducer. Because the CTCs are much larger than the other blood cells, they can be separated by the device which, she says, can also be used for pumping, DNA shearing, cell sorting and separating impurities from water. Garg, who has a strong interest in global health issues, hopes to use the technology to advance point-of-care diagnostics platforms for developing countries. Since the program’s 2004 launch, 560 women from emerging countries, including this year’s 155 awardees, have received Faculty for the Future fellowships to pursue advanced graduate studies at top universities abroad. After completing their studies, the Fellows return to their home countries, contributing to economic, social and technological advancement.

UCI Project Earns People’s Choice Award BME graduate student Jonathan Pegan, working with Associate Professor Michelle Khine, won the People’s Choice award at the UCwide Bioengineering Shark Tank for his work with TinyKicks during the 16th annual UC Systemwide Bioengineering Symposium in June.
Caitlin Regan and co-authors published their paper, “Fiberbased laser speckle imaging for the detection of pulsatile flow,” in the August 2015 edition of Lasers in Surgery and Medicine. The research team designed and characterized a fiber-based laser speckle-imaging system to study pulsatile blood flow in the tooth.
.......................................... ............. Doctotal Candidate Wins Lambert Prize BME doctoral candidate Li Xiao was named one of two winners of this year’s UCI Justine Lambert Prize. The prize is awarded every other year for the best paper submitted by a graduate student addressing issues in natural or social sciences. The Lambert Prize competition is open to all UCI graduate students regardless of department or school affiliation and is made possible by J. Karel Lambert. Xiao’s winning paper was titled “A multi-scale method for dynamics simulation in continuum solvent models I: finite-difference algorithm for Navier-Stokes equation.”
Rockin’ Recovery BME alumnus takes research from lab to marketplace home or in a clinic to augment traditional physical therapy. Flint received several Small Business Innovative Research Grants from the National Institute on Disability and Rehabilitation Research to develop the product and a $1.5 million grant that allowed the new company to manufacture it. Friedman hit upon the idea while working on a hand robot during graduate school. His adviser, Mark Bachman, urged Friedman to design something simpler than the highly complex robots many researchers were working on. A later discussion between Friedman and Bachman – both musicians, as is Zondervan – sparked the idea of adding music to the device. The glove is equipped with sensors on the fingertips that work with a dedicated game console or a touch-screen tablet device. Much in the same way that someone playing Guitar Hero hits buttons on a guitar to sync with notes on the screen, the Music Glove wearer taps notes with his fingertips and thumb to the beat of a song. Playing the game prompts the neural connections between the hand and brain to recover. One wouldn’t expect the leaders of a company specializing in products for stroke patients to be in their mid-20s. But youth is clearly the genius behind Flint Rehabilitation Devices, a startup company founded by UCI engineering alumni Nizan Friedman (pictured above) and Danny Zondervan. Both admit that a few years ago, they didn’t think a whole lot about the 795,000 Americans, mostly older adults, who suffer a stroke each year. But their engineering skills — Friedman in biomedical and Zondervan in mechanical — and their Millennial-generation love of the video games Guitar Hero and Rock Band have placed the duo in the unlikely position of rethinking traditional approaches to stroke rehabilitation. A year ago, their company launched its first product, the Music Glove, a device designed to help stroke patients with hand paralysis regain function. The device can be used at
“The reason our software is inspired by Guitar Hero is because people get addicted to the game,” Friedman says. “We want people to get addicted to therapy. Anything that can motivate people to do therapy for a long time is the right way to go.” Clinical trials demonstrated that the Music Glove produced a threefold improvement in function compared to traditional therapy. “The glove motivates high-intensity movement,” Friedman explains. “People have to complete their movement in order to play the game. If they try to move their finger a little bit but don’t complete that movement they won’t be able to play. It’s also very repetitive. People are doing thousands of movements per hour.” Shari Roan
