08/31/17 - JAKUB TOLAR DELIVERS TALK ON THE TREATMENT OF EPIDERMOLYSIS BULLOSA WITH BONE MARROW TRANSPLANTATION AT THE WORLD CONGRESS OF PEDIATRIC DERMATOLOGY
IEM Member Dr. Jakub Tolar, Executive Vice Dean, Professor of Pediatrics and Director of the Stem Cell Institute, delivered a symposium talk entitled "Cell, Protein and Gene‐Based Therapies for EB," at the World Congress of Pediatric Dermatology. For patients with the most severe types of Epidermolysis Bullosa, bone marrow transplantation has become a promising treatment. Dr. Tolar, who has received widespread news coverage for his treatment of a Canadian teenager who suffers from the disease, says that, while it is not a cure, "it is, however, a path toward understanding how we can treat this grave disorder in a systemic way." Looking to the future, Dr. Tolar says that "it's time to move from two-dimensional science to three-dimensional science; we need to study all aspects of EB simultaneously, from gene to cell to tissue to individual to patient population, and to understand the properties of the whole EB pathobiology that emerge at each level of biological complexity."

08/31/17 - TIMOTHY O'BRIEN AMONG MOST RECENT MN-REACH AWARDEES
IEM Member Dr. Timothy D. O'Brien, Professor of Veterinary Population Medicine, was one of 9 MN-REACH Awardees in its 5th funding cycle, for his project "Midbrain Organoid-Derived Cell Product for Treatment of Parkinson's Disease," a feasibility study to explore the safety and efficacy of the use of cell products derived from brain organoids for transplantation as a treatment for Parkinson's disease. Dr. O'Brien says that his lab has developed an improved method for generating human brain organoids (mini-brains) from induced pluripotent stem cells, which improves the efficiency of production (reducing production costs), consistency of the product, and scalability of manufacturing, compared to currently-used methods. This will "enable, for the first time, a commercially viable means of brain organoid production," says Dr. O'Brien, who adds that the method is "amenable to cGMP-compliant manufacturing, which enables the development of therapeutic cell products from the organoids." Dr. O'Brien is performing these experiments in collaboration with IEM Members Dr. Walter C. Low, Professor of Neurosurgery, and Dr. Jakub Tolar, Executive Vice Dean, Professor of Pediatrics and Director of the Stem Cell Institute.
08/31/17 - PAUL IAIZZO DISCUSSES VISIBLE HEART LAB'S 3D VISUALIZATION SYSTEM WITH THE AMERICAN HEART ASSOCIATION
IEM Member Dr. Paul A. Iaizzo, Professor of Surgery, Principal Investigator of the Visible Heart Lab (VHL) and IEM Associate Director for Education and Outreach, discussed the VHL's 3D Visualization System with the American Heart Association, for a news article on how virtual reality is helping in the treatment of patients with heart disease and stroke. Dr. Iaizzo says that the VHL system has been used by physicians to simulate the placement of leadless pacemakers. "Physicians can drive through the anatomy, blow it up, shrink it, and explain a defect to someone," says Dr. Iaizzo. "The surgeons we've talked to say, 'For the first time, we have an easy tool to better explain to families what we need to do surgically.'" The VHL system was featured along with systems at Stanford University and the University of Pennsylvania.

07/31/17 - IEM-AFFILIATED CENTERS PLAY KEY ROLES IN UTILIZING VIRTUAL REALITY & 3D PRINTING TO PREPARE FOR SUCCESSFUL SURGERY TO SEPARATE CONJOINED TWINS
The IEM-Affiliated Earl E. Bakken Medical Devices Center, Visible Heart Lab, and 3D Printing Core all played key roles in the preparation for a very challenging, but successful surgery to separate twin sisters conjoined at their hearts and livers. These capabilities were required due to the unique aspects of the twins' anatomy and high risks of the procedure. The twins' condition prior to surgery was "extraordinarily shocking," according to IEM Member Dr. Daniel A. Saltzman, Professor of Pediatric Surgery, who performed the operation with his team at the University's Masonic Children's hospital. Dr. Saltzman informed the parents that, as a result of the procedure, they "could lose one or both twins."
The members of Dr. Saltzman's team planned key aspects of the surgery by utilizing the Medical Devices Center's 3D Virtual Prototyping system to visualize both virtual and printed models of the twins' hearts; these were generated from CT and MR images by Alex Mattson, a Biomedical Engineering Ph.D. Candidate within the Visible Heart Lab, and Bethany Tourek, a Mechanical Engineering Ph.D. Candidate within the Medical Devices Center. Mattson also helped Pediatric Cardiologist Dr. Matthew Ambrose utilize both the Medical Devices Center's 3D Virtual Prototyping system and the Visible Heart Lab's 3D Visualization System, which the physician used to perform a virtual walk-through of the twins' anatomy. Dr. Anthony Azakie, Chief of Pediatric Cardiac Surgery, who separated and repaired the twins' hearts, asked Mattson to scrub in on the case based on his knowledge of the anatomy. The Visible Heart Lab's component of the IEM 3D Printing Core was also utilized to print numerous detailed 3D models, some of which were hand painted by Mattson to show relative degrees of blood oxygenation with these conjoined heart anatomies.
What the surgical team members learned by using these tools helped them to better-understand the twins' anatomy and led to a change in the surgical plan, in what ultimately resulted in a successful outcome. And, according to the Washington Post, this may have been the first time that virtual reality has been used to prepare for surgery to separate twins conjoined at their hearts. "It felt like I was working in the future," says Dr. Saltzman. "It was extraordinarily exhilarating."

07/31/17 - John Bischof & Colleagues Develop Advanced Cryopreservation Tool that Utilizes Lasers & Gold Nanoparticles
Dr. John C. Bischof, IEM Associate Director for Development, and Professor of Mechanical and Biomedical Engineering, and his colleagues, have developed an advanced tool that utilizes lasers and gold nanoparticles for the cryopreservation of tissue. The research, entitled "Gold Nanorod Induced Warming of Embryos from the Cryogenic State Enhances Viability," was published in the journal ACS Nano. "Lasers have the exciting ability to act like a 'light switch' that can turn biological activity on and off within gold nanoparticle laden biomaterials," says Dr. Bischof, who was the senior author of the study. "In this case, by careful engineering and deployment of gold nanoparticles within a cryogenically stored and biological inactive embryo, we can use a laser pulse to quickly warm the embryo back to ambient temperatures and switch biological activity, and therefore life, back on."

07/31/17 - Nathaniel Helwig & Collaborators Determine Elements of Successful Smiles
IEM Member Nathaniel E. Helwig, Assistant Professor of Psychology and Statistics, collaborated with Dr. Sophia Lyford-Pike, Assistant Professor, Department of Otolaryngology, Head and Neck Surgery, and Dr. Stephen J. Guy, Assistant Professor of Computer Science and Engineering, to determine the elements of what is referred to as a "successful smile," which is the one that receives the best response. In the research, which was published in the journal PLoS One, a total of 802 participants evaluated computer-generated 3D images of human faces, and rated the smiles on those faces by their effectiveness, genuineness, pleasantness and perceived emotional intent. The results of the study show that the most optimal smiles don't show too much of the person's teeth or gums, are not too wide, develop symmetrically on the right or left side of the face and appear to be natural. "These findings have broad applications in a variety of areas, such as facial reanimation surgery, rehabilitation, computer graphics, and psychology," says Dr. Helwig.
Smiling Too Widely Can be a Social Handicap
07/31/17 - Douglas Yee Discusses Value of Program for Developing Future Cancer Researchers Among Talented Underrepresented Students

07/31/17 - Vipin Kumar Discusses Benefits & Risks of Big Data in Healthcare
IEM Member Dr. Vipin Kumar, Regents Professor of Computer Science and Engineering and William Norris chair in Large Scale Computing, discussed with big data news portal, Datanami, the benefits and risks of big data in healthcare. "Healthcare data about the population at large can be analyzed to create individualized treatments, an area also known as precision medicine," says Dr. Kumar. But along with those benefits are risks and moral implications of how the data will be used. "There are huge concerns about possible misuse of these kinds of information, such as discrimination in hiring or in purchasing health insurance, if this information is not handled properly," says Dr. Kumar. "The healthcare community is on the front lines in this area, but, given the complexity of issues involved, progress in addressing these concerns is very slow."

06/29/17 - Research Led by David Odde Increases Understanding of How Cancer Cells Spread
IEM Executive Committee Member Dr. David J. Odde, Professor of Biomedical Engineering, led a study that has increased the understanding of how cancer cells use their ability to assess their surroundings to migrate through those environments. The research, which was partly funded by IEM and published in Nature Communications, could eventually lead to the development of therapies that would inhibit the spread of cancer. Dr. Odde says that "Cells are a little like the storybook character Goldilocks. They don't like their environment too hard or too soft--it needs to be just right or they won't move well," and that "If we can trick cancer cells into believing it is not a good environment for migration, we can limit the cancer cells spreading in the body." A distinguishing aspect of the research, according to Dr. Odde, was its approach of combining math and physics to build models that were then tested experimentally, noting that the research team "brought an engineering approach to an important medical problem."

06/29/17 - FDA Approves Jaw Fracture Recovery Device that Evolved from MDC's Innovation Fellows Program
A jaw fracture recovery device that was created by Dr. Alan Johnson during his Innovation Fellowship at the IEM-affiliated Medical Devices Center (MDC) has received FDA approval to be marketed to surgeons by Summit Medical, which developed the device after licensing the technology from the University during Dr. Johnson's Fellowship year. The Minne Ties Agile MMF, an apparatus that restrains jaw mobility following a fracture, can be inserted more easily than traditional wire-based systems, leading to less discomfort for patients and resulting in an easier procedure for physicians - one that may be performed in clinics, instead of in expensive operating rooms. Dr. Johnson, who is now a head and neck surgeon in Grand Forks, North Dakota, invented the device in 2012 with co-inventors Laura-Lee F. Brown and Dr. Christopher Rolfes, who were also MDC Innovation Fellows, and IEM Member Dr. Samuel C. Levine, Professor in the Department of Otolaryngology, Head and Neck Surgery.
Even with a potentially successful device such as this, that path can be arduous, according to IEM Executive Committee Member Dr. Arthur G. Erdman, Professor of Mechanical Engineering and Director of the Medical Devices Center. "The concept was simple and elegant, but he still faced significant engineering and manufacturing challenges." The Medical Devices Center played a major role in overcoming those challenges. "Alan took full advantage of the prototyping facilities at MDC," says Dr. Erdman. "It seemed that each time I looked at the mechanical fabrication lab across from my office, I would see Alan busy making improvements on earlier prototypes. The numerous design-build-test cycles brought the project to a point where Summit Medical could evaluate the finished proof-of-concept." This will be the first product to reach the market from the MDC Innovation Fellows program.

06/29/17 - William Pomerantz Part of Research Team that Discovers Potential Drug Target for Treating Breast Cancer
IEM Member Dr. William C. Pomerantz, Assistant Professor of Chemistry, and his colleagues at the Cold Spring Harbor Laboratory in New York and Cancer Research UK at Cambridge University have identified a protein that could serve as a target for drugs to treat breast cancer. The protein, called BPTF, needs to be present in undifferentiated breast cells for them to multiply, including in the indefinite way that cancer cells multiply. With the knowledge of the dependency mammary cells have on BPTF, researchers can pursue ways in which that dependency can be utilized to target the protein in breast cancer cells. The research was published in Stem Cell Reports and led by PI Camila dos Santos at Cold Spring Harbor Labs. A second co-investigator was Professor Gregory Hannon of Cancer Research UK, Cambridge Institute.
06/29/17 - Wei Chen, Kamil Ugurbil and Xiao-Hong Zhu Among Team that Developed New Brain Research Tool that Combines MRI & Microscopy
IEM Executive Committee Member Dr. Wei Chen, Professor of Radiology, and IEM Members Dr. Kamil Ugurbil, CMRR Director and Professor of Radiology and Xiao-Hong Zhu, Associate Professor of Radiology, collaborated with Dr. Meng Cui, a leading expert in optical imaging at Purdue University, to develop a way to combine functional MRI with microscopy to develop a better understanding of brain circuitry and function. As reported in HEALTHCANAL, the new approach allows for the sophisticated microscopy needed for this research to be performed with functional MRI, which was previously not possible, due to the detrimental effects of the powerful magnets on the delicate electronics used for microscopy. The system achieves this by situating both the laser and optoelectronics far from the MRI equipment, while delivering light to and receiving light from the specimen, remotely. The research was published in the journal Scientific Reports.
06/29/17 - Mark Thomas Discusses a New Vaccine to Treat Heroin Addiction with Newsweek
IEM Member Dr. Mark J. Thomas, Associate Professor of Neuroscience, discussed with Newsweek a new vaccine that blocks the high experienced by users of heroin. Developed by scientists at the Scripps Institute, the vaccine works by introducing the high-inducing components of heroin into the immune system, against which the system generates antibodies that prevent those elements from reaching the brain. Researchers believe that eliminating the high could help to prevent heroin addicts from relapsing. Dr. Thomas, who did not participate in the research, cautions that, while the vaccine shows promise for former users of heroin, "it's not going to be a panacea," as those users will likely seek a replacement to the drug.
New Vaccine Could Stop Heroin High Abuse
06/29/17 - Essa Yacoub Discusses CMRR's Leading-Edge Brain-Mapping Research with Star Tribune
IEM Member Dr. Essa Yacoub, Professor of Radiology in CMRR, discussed with the Star Tribune brain-mapping research at the University's Center for Magnetic Resonance Research (CMRR), which seeks to map brain connectivity among babies, children, and older adults, and determine how it varies with aging and disease. Dr. Yacoub says that the objective is to determine what "healthy development looks like or what healthy aging looks like," and that researchers are also "looking for variations in connectivity or how the brain circuitry is altered in [people with] diseases." The research is being performed as part of the Human Connectome Project, an NIH-sponsored collaboration among multiple institutions to map the human brain, with the aim of connecting its structure to function and behavior. The CMRR is a key collaborator in this research, due to its especially-powerful imaging capabilities.

05/30/17 - Jerrold Vitek Discusses Abbott's New DBS Lead with Star Tribune
IEM Member Dr. Jerrold L. Vitek, Professor and Chair of the Department of Neurology, discussed with the Star Tribune, the advantages of a new, segmented lead for Deep Brain Stimulation (DBS) to treat movement disorders, such as Parkinson's disease, dystonia, and essential tremor. The Infinity DBS Lead, manufactured by Abbott (formerly, St. Jude Medical), is unique from other leads, which distribute electric current spherically, in that it has the capability to deliver the current to specific areas of the brain where it is most needed and to avoid areas where the current could lead to unwanted side-effects. Dr. Vitek, who describes the lead's capability as "the first real advance" in the field during the past 20 years, says that "being able to sculpt this current field allows us to push current in directions that improve motor signs while avoiding regions that induce side effects."
Abbott's Infinity Deep Brain Stimulation System is Rare Technology Advance
05/30/17 - David Boulware Authors Study in The Lancet Infectious Diseases on Impact of HIV-Associated Cryptococcal Meningitis
IEM Member Dr. David R. Boulware, Professor of Infectious Diseases and Internal Medicine, was the senior author of a study published in The Lancet Infectious Diseases on the impact of Cryptococcal Meningitis in people infected with HIV. The condition, which affects tissues that cover the spinal cord and brain, can be easily identified and inexpensively treated. Yet, the disease is responsible for approximately 15% of the 1,100,000 deaths related to AIDS due to patients entering HIV treatment too late and a lack of access to the medication needed to treat it in the sub-Saharan African countries where it is the most prevalent. Dr. Boulware states that "Still too many HIV-infected people enter care late and Cryptococcal Meningitis is an unfortunate excellent metric of HIV treatment program failure. In 2017, no person with HIV should develop fungal meningitis, yet in a failed cascade of HIV care, too often Cryptococcus is a final death sentence."

05/30/17 - Paul Iaizzo Leads Study Showing that Delta-Opioid Agonists can Minimize Cardiac Injury Following Heart Procedures
Dr. Paul A. Iaizzo, Professor of Surgery, IEM Associate Director for Education and Outreach, and Principal Investigator of the IEM-Affiliated Visible Heart Laboratory (VHL), led a study published in Experimental Biology and Medicine (the Featured Article) that demonstrated the effectiveness of a post-conditioning therapy for minimizing damage to a heart following cardiac procedures and during reperfusion (when blood flow is restored). Dr. Iaizzo's team tested a delta opioid receptor agonist as a supplement to an existing reperfusion buffer for reanimated isolated swine hearts and found that it improved the microvascular functionality of the heart compared to control subjects. These results suggest that this may be a promising treatment for many people who undergo cardiac procedures involving reperfusion. "The opportunity to utilize post-conditioning pharmacological agents to improve cardiac function will have significant applications in both cardiac surgery and transplantation," says Dr. Iaizzo.

05/30/17 - Rita Perlingeiro and Colleagues Identify Endoglin as a Potential Target for Treatment of Acute Leukemias
IEM Member Dr. Rita Perlingeiro, Professor of Medicine/Cardiology, and her colleagues were published in the journal Blood for their research showing that the receptor endoglin is a potential target for the treatment of acute myeloid leukemia (AML) and B-cell acute lymphoblastic leukemia (B-cell ALL), as it is expressed in the majority of the cancerous cells. In addition, the research showed that a drug, TRC 105, manufactured by Tracon Pharmaceuticals, inhibited the progression of these leukemias. The findings are especially significant, as the National Cancer Institute estimates that AML will be diagnosed in approximately 21,380 Americans in 2017 and that 10,590 will die from the disease, while the equivalent numbers for B-cell ALL are 5,970 and 1440, respectively. In 2016, Dr. Perlingeiro and her IEM member colleagues demonstrated the role endoglin plays in the embryonic development of blood and cardiac cells.

05/30/17 - Michael McAlpine Discusses Bionic 3-D Printing Applications with NBC News
IEM member Dr. Michael C. McAlpine, Benjamin Mayhugh Associate Professor of Mechanical Engineering, discussed with NBC News the potential of printing 3-D devices on a human body. In research recently published in the journal Advanced Materials, Dr. McAlpine demonstrated how 3-D printing can be used to fabricate stretchable, electronic tactile sensors onto curved surfaces, including human skin, as the materials can be printed and cured at room temperature. Dr. McAlpine says that this capability could eventually make it possible for a variety of electronic devices to be printed onto a human body and for this to be done in mobile environments from a portable 3-D printer that could be carried around in a backpack. "Using only raw materials, you can make basically any type of device - that's a complete paradigm shift that hasn't been implemented before," says Dr. McAlpine.

05/30/17 - Andrew Grande Discusses Stroke Awareness with WCCO
As part of Stroke Awareness Month, IEM Member Dr. Andrew W. Grande, Assistant Professor of Neurosurgery, discussed with WCCO the types of strokes, their symptoms and the resulting actions that patients and bystanders should take, to generate more awareness of stroke among the general public - knowledge that could help people to minimize the long-term damage of stroke and, in some cases, save lives. A simple rule of thumb for recognizing and acting upon the more-common ischemic stroke is to remember the acronym F.A.S.T., which stands for: Face Drooping, Arm Weakness, Speech Difficulty (both speaking and understanding speech) and Time to Call 911! Dr. Grande says that if patients get the care they need within 3 to 6 hours of the onset of these symptoms, the damage and resulting symptoms can be reversed.
05/30/17 - Timothy O'Brien Discusses Advance in Production of Cerebral Cell Structures with Duluth News Tribune
IEM member Dr. Timothy D. O'Brien, Professor, Department of Veterinary Population Medicine, discussed with the Duluth News Tribune the significance of his research that was recently published in Stem Cells Translational Medicine to produce brain organoids from human induced pluripotent stem cells using a cell matrix technology being commercialized by a company in Two Harbors, Minnesota, that allows scientists to grow cerebral tissue in more natural, three-dimensional structures. "This is potentially really important because they could be used for development of drugs for neurological problems - to check for beneficial or toxic effects of drugs," says Dr. O'Brien, who adds that the end result is "much more like a real brain than what people have had access to before." Another valuable aspect of the technology is its versatility. "One of the interesting twists from this is since the stem cells can be derived from anybody, they can be derived from patients with Parkinson's disease or Alzheimer's ... to use as a disease-in-a-dish sort of model," says Dr. O'Brien.

04/28/17 - Brenda Ogle & Colleagues Create 3D-Bioprinted Patch to Heal Scarred Heart Tissue
IEM Member Dr. Brenda M. Ogle, Associate Professor of Biomedical Engineering, and her colleagues have created a 3D-bioprinted patch that can help to heal heart tissue following a heart attack. As reported by KSTP TV and KARE 11, the research, done in collaboration with the University of Wisconsin and University of Alabama-Birmingham, used laser-based 3D-bioprinting to apply human stem cells to a matrix, which grew and synchronously beat in a dish. The resulting patch was then applied to non-functioning scarred tissue in mouse hearts, which showed improved function after four weeks. This achievement is especially significant because survivors of heart attacks often permanently lose some heart function. "We don't get new muscle cells when they are damaged, instead, we get scar tissue," says Dr. Ogle, who has been working on the challenge of regenerating damaged heart tissue for 15 years. The next steps will be to test the patch on larger animals before, ultimately, testing it on humans. The research was funded, in-part, by IEM.

04/28/17 - Rumi Faizer Discusses with KARE 11 Value of New Method to Screen for Abdominal Aortic Aneurysms
IEM Member Dr. Rumi Faizer, Associate Professor of Surgery and Chief, Division of Vascular Surgery, discussed with KARE 11 the value of a new, life-saving screening method that was developed at the University of Minnesota to identify patients who have the highest likelihood of developing abdominal aortic aneurysms (AAA), potentially lethal and sometimes symptomless vascular condition in which the aorta, the main vessel through which blood is delivered throughout the body, becomes enlarged. Dr. Faizer says that what makes the University of Minnesota's screening unique from those at other centers is that it evaluates patients for whom screening would not be appropriate, targeting only those patients who would benefit the most from it. The screening has already found 29 aneurysms in over 1,500 patients tested so far with annual ultrasounds, and efforts are underway to build upon that success, using CT scanning. "We've developed a system to identify who needs to be screened and then we are trying to work on new ways to do that screening," says Dr. Faizer.
04/28/17 - Michael Kyba Discusses Research on Type of Muscular Dystrophy with Fox 9
IEM Member Dr. Michael Kyba, CCRF Endowed Professor in Pediatric Cancer Research, discussed with Fox 9 his research on facioscapulohumeral muscular dystrophy (FSH), a common type of muscular dystrophy in which skeletal muscles degenerate over time, starting with the facial muscles. Dr. Kyba says that "one of the saddest things that happens" to patients suffering from FSH is that "they are robbed of their ability to smile." However, Dr. Kyba is optimistic that a treatment for the disease can be developed, due to the identification of the gene that causes it. "The hope comes down to there is actual work being done to discover the drug. About 10 years ago, we didn't know what gene caused this disease," says Dr. Kyba. "That's our hope that someday in the near future we'll have candidates that we can actually take to clinical trials."
04/28/17 - Chetan Shenoy Discusses a Less-Invasive Imaging Approach in Management of Stable Angina with TCTMD
IEM Member Dr. Chetan Shenoy, Assistant Professor of Medicine, Cardiovascular Division, discussed with TCTMD the value of stress cardiovascular magnetic resonance (CMR) perfusion imaging in the management of patients with stable angina, compared to that of the more-invasive angiography plus fractional flow reserve (FFR). The two approaches were compared in a recent trial. "As someone who does stress CMR, the trial results were not very surprising to me," says Dr. Shenoy. As a result of the findings, Dr. Shenoy says, "Stress CMR can and should be used as the first-line test for patients with stable angina and intermediate-to-high risk of coronary artery disease, rather than invasive coronary angiography."
CMR Perfusion Imaging Holds Its Own Against Invasive Approach to Managing Stable Angina
03/29/17 - Registration for Minnesota Neuromodulation Symposium on April 13th & 14th is Rapidly Approaching its Limit

Dr. John C. Bischof, IEM Associate Director for Development, and Professor of Mechanical and Biomedical Engineering, along with his IEM colleagues, have successfully demonstrated a method to safely warm vitrified tissue, a major step toward cryopreservation of human tissues and organs for transplantation. A barrier to preserving large tissues and organs by cooling (or vitrification) is that the tissue crystalizes and can also crack during the warming process, damaging the tissue. As reported by the Associated Press, Dr. Bischof's team has overcome this by using iron oxide nanoparticles that, when heated by radiofrequency fields, allow for a uniform and rapid warming of the vitrified tissue. This method, known as nanowarming, could eventually be applied to entire organs, and ultimately result in helping to meet tissue and organ demand of those needing transplants. However, this will require more years of research to achieve. "We are cautiously optimistic that we're going to be able to get into a kidney or maybe a heart. But we are not, in any way, declaring victory here," says Dr. Bischof. Other IEM members on Dr. Bischof's team included IEM Executive Committee Member Dr. Christy L. Haynes, Professor and Vice Chair, Department of Chemistry; Dr. Alex Fok, Professor of Restorative Sciences; and Dr. Michael Garwood, Professor of Radiology-CMRR. The research has been published in Science Translational Medicine.

03/29/17 - Angela Panoskaltsis-Mortari Leads University's Joining of Consortium to Bolster Advanced Tissue Biofabrication
IEM Member Dr. Angela Panoskaltsis-Mortari, Professor of Pediatrics and Medicine, and Director of the 3D Bioprinting Facility, led the submission process for the University of Minnesota's successful bid with the Advanced Regenerative Manufacturing Institute (ARMI), a consortium of nearly 100 organizations spanning industry, government, academia and the non-profit sector, for a new manufacturing institute partly funded by the DoD. Approximately $80 million from the federal government will be combined with more than $200 million in cost share to support the development of tissue and organ manufacturing capabilities. "This initiative is a great way to build our bioprinting and education expertise in a collaborative way with other leading organizations," says Dr. Panoskaltsis-Mortari. "Regenerative medicine and biofabrication is an opportunity area for our healthcare and manufacturing industries, and we're excited to be part of an effort that could benefit patients and our economy."
As part of its role in the consortium, which will be supported with a $3.5 million budget, the University of Minnesota is expected to lead the development and expansion of training curricula for K-12, 2- and 4-year colleges, industry professionals and veterans, that will educate students about Tissue and Organ Biofabrication, 3D Bioprinting and Regenerative Medicine. Dr. Panoskaltsis-Mortari expects allocation and scope of work to be finalized by the summer of 2017. The Institute for Engineering in Medicine, the IEM-affiliated Medical Devices Center, Stem Cell Institute, Molecular & Cell Therapy Facility, 3D Bioprinting Facility, STEM Education Center and many others will play vital roles in this initiative.

03/29/17 - David Odde Discusses Effort to Engineer Bacteria-Eating Cells with Baltimore Sun
IEM Executive Committee Member Dr. David J. Odde, Professor of Biomedical Engineering, discussed with the Baltimore Sun a research effort at Johns Hopkins University to engineer amoebas, single-cell organisms, to become bacteria-eating cells. While the research is focused upon using the cells to kill the bacteria that cause Legionnaire's Disease, and a drug-resistant bacteria that affects hospital patients, what is learned from how the cells can be engineered could lead to advances in treating other diseases, including cancer. Dr. Odde says that a key factor is getting the cells to sense the bacteria. "They might make new discoveries about how these systems cross talk to each other which will be really valuable for this project and many other projects," says Dr. Odde.
03/29/17 - Christopher Weight Discusses Prostate Cancer Surgery with KARE 11
Dr. Christopher J. Weight, Assistant Professor of Urology, and IEM Member, was interviewed by KARE 11 to discuss prostate cancer surgery, soon before Governor Dayton had surgery to treat his prostate cancer at the Mayo Clinic on March 2nd. Dr. Weight says that most of these procedures are performed with robotic assistance and that they are among the most common types of cancer surgeries performed in the U.S. "It used to be all done through an open incision, which was about an 8 centimeter incision going from the belly button down to the pubic bone," says Dr. Weight. "Now it's usually five or six small incisions about 8 millimeters, which is a little bit smaller than the tip of my finger."
03/29/17 - Marc Tompkins Co-Authors a Study Published in the Journal Pediatrics on Increase of ACL Tears Among 6 to 18 Year-Olds
IEM Member Dr. Marc Tompkins, Assistant Professor of Orthopeadic Surgery, co-authored a study in the journal Pediatrics that showed an increase in ACL tears among children 6 to 18 years of age, over the 20-year period of 1994 to 2013. The increase of 2%, annually, during that period has been especially pronounced for girls. While the reason for the increase was unclear, Dr. Tompkins says that it could be due to increased specialization in a particular sport, greater intensity and force of play, and a general increase in sports participation among girls during those 20 years. However, he notes, it could also be due to better diagnostics. "We are getting better as a medical community at diagnosing ACL injury," says Dr. Tompkins. The first author of the study was Dr. Nicholas A. Beck, a Medical Resident in Orthopaedic Surgery.

03/29/17 - Emil Lou Discusses Increase of Colon & Colorectal Cancers Among Millennials & Generation Xers
Dr. Emil Lou, Assistant Professor of Medicine, and IEM Member, discussed with the University's Health Talk a recent study showing an increase of colon and colorectal cancers among Millennials and Generation Xers. Compared to Americans born in 1950, those born in 1990 are twice is likely to be diagnosed with colon cancer and four times as likely to be diagnosed with rectal cancer. Dr. Lou says that "the findings of this study are extremely alarming," and that "they indicate a strong need to increase awareness among medical professionals that young adults can actually get colorectal cancer." Possible causes of the increase could include lifestyle factors of people 20 to 30 years of age, such as a poor diet, sedentary lifestyle, excess weight and a low consumption of fiber, all of which have also contributed to an epidemic of obesity.

02/27/17 - Kamil Ugurbil Discusses Data Capacity Needed for Brain Mapping with Scientific American
IEM Member Dr. Kamil Ugurbil, Professor of Radiology-CMRR, discussed with Scientific American, the tremendous amount of data storage capacity needed for mapping the human brain, which is far greater than the capacity used for the mapping of the human genome. This was a big factor in the Human Connectome Project (HCP), a global consortium funded by the U.S. Government that published a map of the human brain. Dr. Ugurbil, who is Co-Principal Investigator of the HCP, says that the project's researchers used 6 terabytes of MRI data for the analysis of 210 adults when mapping the human cerebral cortex. To address the need for far greater data processing and storage capacity to fully research the connectivity of the human brain, including its 86 billion neurons, scientists are developing innovative data analysis techniques and are also working more collaboratively than they traditionally have in the past.

02/27/17 - Kelvin Lim & Mark Thomas Profiled for Research Effort to End Addiction
IEM Executive Committee Member Dr. Kelvin O. Lim, Professor of Psychiatry, and IEM Member Dr. Mark J. Thomas, Associate Professor of Neuroscience, were featured in the University's publication Driven to Discover for their research efforts to address the relapse that occurs in approximately 80-90% of addiction patients within one year of recovery. Dr. Lim's research focuses on predicting those patients most likely to relapse, by using brain scans to determine the level of communication between the brain's nucleus accumbens, its rewards and pleasure center, and the frontal cortex, its decision-making center. "The stronger that communication is," says Dr. Lim, "the Higher your chance of staying abstinent." Dr. Thomas says that his research focuses on understanding "what the neural signature for relapse is," so that it can be interrupted. His research team has found a circuit in mice that, when stimulated, can block the relapse of addiction, and he hopes to eventually translate that treatment to humans.
02/27/17 - Michael Garwood Profiled for Effort to Develop Smaller, More Affordable MRI for Brain Imaging
IEM Member Dr. Michael Garwood, Professor of Radiology-CMRR and Member of IEM Academy of Medical Device Innovators, is working to develop a portable MRI system for scanning a patient's brain, with the support of the NIH BRAIN Initiative. The system, which aims to be much more compact and affordable than currently-used MRI systems, is made possible by Dr. Garwood's technology, which allows for quality images to be produced with only 1/3000 the amount of magnetic field uniformity of today's MRI systems. "It's a smaller tube, all the same technology," says Dr. Garwood. "We can now make good images with a magnet that's not very uniform, which means that now we can make it small, and you can imagine that it's going to be a lot cheaper." Dr. Garwood adds that the technology has the potential for much broader applications, such as mammography, and that its mobility and low-cost could make MRI available to the 90% of humanity that currently lacks access to it.
02/27/17 - Matthew Johnson Develops Algorithm to Identify Optimal DBS Parameters for Individual Patients
IEM Member Dr. Matthew D. Johnson, Associate Professor of Biomedical Engineering, and his team of researchers have been looking at different methods of deep brain stimulation (DBS) that will optimize the therapeutic outcome on an individual basis for patients with DBS lead implants. Most recently, Dr. Johnson and his team have developed a Particle Swarm Optimization method for DBS leads with more advanced electrode configurations to maximize the amount of therapeutic benefit, while minimizing both induction of side-effects and overall battery power consumption of the treatment. His team's approach of optimizing particle swarms to address this challenge was inspired by nature, where organisms "solve these complex problems all the time through swarms of cooperating individuals," says Dr. Johnson.
02/27/17 - The Star Tribune Features Douglas Yee Commentary on Need for Robust Funding to Fight Cancer
IEM Member Dr. Douglas Yee, Professor of Medicine and Pharmacology and Director of the Masonic Cancer Center, wrote a commentary in The Star Tribune to advocate for strong funding in cancer research. Dr. Yee's piece was in response to a previous commentary that questioned the necessity for the large amount of federal support for this research, including the recent $1.8 Billion of funding for the Cancer Moonshot. Dr. Yee counters that "essentially all of the 'breakthrough' cancer therapies were created from federally funded research projects," and that "these successes account for the estimated 15.5 million cancer survivors (about 5 percent of the population) in the United States." In reference to the recent funding boost, Dr. Yee states that the Cancer Moonshot "isn't meant to rocket us all away from this disease, but rather to provide resources to create a stronger mission control." Dr. Yee states that "it is reasonable to believe, with the right resources, we can make cancer preventable, manageable, treatable, or curable."
Sorry But Robust Funding is Way to Conquer Cancer

01/27/17 - Teresa Kimberley Awarded $1.5 Million NIH Grant to Pursue Treatment of Rare Movement Disorder
IEM Member Dr. Teresa J. Kimberley, Associate Professor in the Division of Physical Therapy and Rehabilitation Science, was awarded a $1.5 million NIH Grant to investigate the pathophysiology in dystonia, a rare movement disorder. This will build upon Dr. Kimberley's previous work, in which she led a team of IEM members to develop a novel method for measuring cortical excitability in deep or intrinsic muscles. That early work was supported by NIH, MnDRIVE and IEM. The new, NIH-funded project will combine non-invasive brain stimulation and neuroimaging to determine brain network function in people with different types of focal dystonia compared to that function in healthy people. "Dystonia is an enigmatic movement disorder, but I am optimistic that the innovative technology and techniques we are using will lead to a breakthrough in understanding this disorder and help lead to meaningful treatment development," says Dr. Kimberley.
01/27/17 - University Commits $2.5 Million to Greg Beilman & Colleagues for Development of Therapy to Treat Traumatic Blood Loss
IEM member Dr. Gregory J. Beilman, Professor of Surgery, is a part of a three-person research team at the Twin Cities and Duluth campuses of the University of Minnesota that is seeking to commercialize a drug therapy to treat victims of traumatic blood loss. As reported in Twin Cities Business, D-beta hydroxybutyrate and melatonin (BHB/M) therapy has been in development since 2005, and both on and off the commercialization track as economic factors fluctuated. Recently, however, the University's Center for Translational Medicine has given the team a $2.5 million grant to continue research on BHB/M therapy. With the renewed interest in the treatment, the team hopes to complete the preclinical work that will put the drug on track for clinical trial approval from the U.S. Food and Drug Administration.
01/27/17 - Michael Walters Cited by Scientific American for Research Review Showing no Therapeutic Benefit to Curcumin
IEM Member Dr. Michael A. Walters, Research Associate Professor of Medicinal Chemistry and Director of the Lead and Probe Discovery Core of the Institute for Therapeutics Discovery and Development (ITDD), was cited by Scientific American for a review of thousands of research papers and over 120 clinical trials, showing no therapeutic benefit to curcumin. The molecule is part of the spice turmeric, which has been popularized in literature as having health benefits. "People accept what is in the literature as being correct and then build a hypothesis, even though it doesn't hold up," says Dr. Walters, who was the lead author of the review, published in the Journal of Medicinal Chemistry. Dr. Walters describes their findings on curcumin research as a "cautionary tale," and scientists hope that it will prevent others from pursuing what they believe would be futile efforts.

01/27/17 - Douglas Yee Discusses Potential Effectiveness of Immunotherapy in Eliminating Dormant Breast Cancer Cells
IEM Member Dr. Douglas Yee, Professor of Medicine and Pharmacology and Director of the Masonic Cancer Center, discussed the potential effectiveness of immunotherapy in eliminating dormant breast cancer cells at the San Antonio Breast Cancer Symposium in December. As reported in HemOnc Today, Dr. Yee says that current breast cancer treatments focus upon tumor cells which are actively dividing because "we have an inability to eradicate - or kill - dormant non-dividing tumor cells," which results in the need for physicians and their patients to be continually vigilant for a recurrence of the cancers when they're in remission. However, Dr. Yee says that he has "a lot of hope" that immunotherapies, particularly those utilizing checkpoint inhibitors, can eliminate dormant cancer cells if appropriately tumor cell antigens can be found. "One of the things we have to work hard on is how do we get the immune system, when it's unshackled from checkpoint inhibition by PD-L1 inhibitors, to identify dormant estrogen receptor-positive breast cancer cells. We have developed many monoclonal antibodies over the years that have recognized estrogen receptor-positive breast cancer cells that could serve as neoantigens for an immune attack," says Dr. Yee.
Immunotherapy Holds Potential to Eliminate Dormant Lethal Cancer Cells
01/27/17 - Visible Heart Lab Adds Virtual Realty System to its Capabilities
The IEM-affiliated Visible Heart Laboratory has recently unveiled a new virtual reality system that allows users to explore the insides of 3D heart models. Inspired by the desire to expand upon traditional classroom learning, this system gamifies conventional anatomical modeling to provide students and researchers with a unique, virtual tour of numerous aspects of various heart models, including different tissues, chambers, and even implantable medical devices. Though only several months old, this system has already attracted students, physicians, and industry members alike to experience this novel technology.
The team behind the system, led by graduate student Erik Gaasedelen, hopes to begin to introduce sound, motion, and real-world situations, like catheter insertion, into the model, allowing for more user interaction with the system. The Visible Heart Lab's Principal Investigator, Dr. Paul A. Iaizzo, Professor of Surgery and IEM Associate Director for Education and Outreach, stated that many groups of clinicians and researchers from around the world have come to see the system and have remarked about its potential for training fellows and medical residents. "There is a huge opportunity for the use of this system/approach beyond its current educational function," Dr. Iaizzo notes. "This system will allow physicians to train and practice procedures before entering the operating room or cathlab."
