12/22/16 - IEM Director Bin He and Research Team Made Breakthrough in Mind-Controlled Robotic Arm
A first-of-its-kind mind-controlled robotic arm that utilizes technology developed by Dr. Bin He, Professor of Biomedical Engineering and director of IEM and the Center for Neuroengineering (CNE), was featured by a variety of media including the Star Tribune, Fox News, KSTP, and Fox 9. "This is the first time in the world that people can operate a robotic arm to reach and grasp objects in a complex 3-D environment using only their thoughts without a brain implant," says Dr. He. Building upon technology Dr. He developed for mind-controlled drones, the robotic arm system is a big step toward a future of medical applications that could range from rehabilitating stroke patients to helping paralyzed patients regain the ability to perform basic tasks in their everyday lives. This non-invasive technology also has unique merits compared to more expensive and risky implantable technologies aimed at achieving similar outcomes. The work was published last week in Scientific Reports, a Nature research journal.

12/22/16 - Blood Washing Device Invented by Allison Hubel is Featured by Twin Cities Business
A blood washing device invented by IEM Executive Committee Member Dr. Allison Hubel, Professor of Mechanical Engineering, and Director of the IEM-affiliated Biopreservation Core Resource (BioCoR), was featured by Twin Cities Business. The automated system cleanses from thawed blood glycerol preservatives, which are added to blood prior to its freezing for storage, and it does so more efficiently and safely than does a centrifuge, which has been the standard type of equipment used for this process and which requires more time and labor to use and results in high cell losses. Dr. Hubel's device could ultimately help to make large strategic reserves available from blood produced from stem cells, during emergencies when insufficient quantities of donated blood are available - something which is not as possible with centrifuges. The device took a big step toward this future with a $223,000 Phase I NIH SBIR grant awarded in September to the start-up company seeking to commercialize it, Headwaters Innovation Inc., led by a successful local entrepreneur.

12/22/16 - Henry Balfour Discusses Epstein-Barr Virus with USA Today
IEM Member Dr. Henry H. Balfour, Jr., Professor of Laboratory Medicine and Pathology, was interviewed by the USA Today about Epstein-Barr Virus (EBV), commonly-known as mono and "childhood kissing disease." Dr. Balfour says that the disease can potentially have long-term consequences for those who suffer from it, including the 280,000 college freshmen that contract the disease, annually. "Epstein-Barr Virus is responsible for a number of chronic conditions, especially certain forms of cancer and autoimmune disease and even multiple sclerosis," says Dr. Balfour. Symptoms of the disease experienced later in life can include symptoms of the flu that don't completely subside, joint pain and ringing in the ears, according to Dr. Balfour, who adds that the EBV virus can also lead to chronic fatigue and fibromyalgia. Dr. Balfour, who's research is focused on the development of a vaccine against EBV, says that "the best way to deal with all these EBV diseases is to prevent them from happening in the first place."

12/22/16 - Kelvin Lim Discusses Use of Ecstasy to Treat PTSD with KARE 11
Dr. Kelvin O. Lim, Professor of Psychiatry, Drs. T.J. and Ella M. Arneson Land Grant Chair in Human Behavior and Co-Chair of IEM's Neuroengineering Theme was interviewed by KARE 11 about new, FDA-approved Phase III clinical trials of the party drug Ecstasy (MDMA) for the treatment of PTSD. MDMA is classified as a Schedule 1 drug with no currently accepted medical use. The new trials build upon research that included a trial in which MDMA was used as part of a broader treatment regimen, including therapy, that resulted in a 56% decrease in the severity of symptoms of PTSD and two-thirds of the patients no longer meeting the criteria for having the disorder. Dr. Lim, who has not studied MDMA, says that the potential use of MDMA to treat PTSD is "very promising and exciting" due to the lack of effective medications and that "thirty to forty percent of people don't respond to treatment". However, Dr. Lim cautions that if MDMA is approved as treatment for PTSD, mechanisms will need to be put in place to insure that it used in a safe and effective manner.

12/22/16 - Melena Bellin Discusses with Reuters Health Testing to Predict Insulin Dependence Following Total Pancreatectomy with Islet Autotransplantation
Dr. Melena D. Bellin, Associate Professor of Pediatrics, discussed with Reuters Health the results of a study suggesting that the Lower Oral Glucose Tolerance Test (OGTT) can help to predict the insulin dependence of chronic pancreatitis patients following total pancreatectomy with islet autotransplantation (TPIAT). The research showed a relationship between patients' glucose status prior to the procedure, as measured by OGTT, and the need for insulin therapy one year after the procedure. "While risk of diabetes is most often a secondary consideration (to pain control/quality of life) in selecting patients for TPIAT, it is very important that patients are provided a realistic expectation of outcomes in preoperative counseling," says Dr. Bellin, who adds that "Some patients may choose not to undergo TPIAT knowing that their testing before surgery puts them at very high risk for lifelong insulin dependence after surgery."
OGTT Testing May Help Counsel Patients Before Total Pancreatectomy with Islet Autotransplantation

11/28/16 - IEM Industrial Advisory Board Member Among Brain-Computer Interface Investigators Published in New England Journal of Medicine
IEM Industrial Advisory Board Member Dr. Timothy Denison, Vice President of Research and Core Technology, and Technical Fellow at Medtronic, was among investigators whose research, on the use of a fully-implanted brain-computer interface (BCI) for communication by an ALS patient, was published in the New England Journal of Medicine. The patient suffers from "locked-in syndrome," a form of paralysis which prevents her from being able to communicate verbally or in other muscular-based ways, but which does not affect her cognitive ability. By thinking about moving her fingers, the patient generates a brain signal that is identified and converted into a mouse click by the BCI system, allowing her to then select individual letters on a keyboard and type messages. Dr. Denison says that the next objectives are to make the technology operate faster and useable in a home environment. The research was performed at the University Medical Center (UMC) Utrecht, in the Netherlands, and was funded, in-part, by Medtronic.

11/28/16 - Jakub Tolar Speaks at Conference in Cuba to Promote Collaborative Research in Regenerative and Cellular Medicine
IEM Member Dr. Jakub Tolar, Professor of Pediatrics, Director of the Stem Cell Institute and Executive Vice Dean of Medical School, was among the speakers at the inaugural Inter American Regenerative and Cellular Medicine Conference, which was held in Havana, Cuba, October 13th through 15th. The conference, which hosted 180 medical professionals from 14 countries, focused upon the potential standardization of stem cell therapies in medicine. Dr. Tolar says that the conference "was a fine example of how international research starts with human interactions," and that being "derived in part from shared knowledge of regenerative medicine literature and in part from the shared goal of alleviating human suffering anywhere in the world, the meeting of Cuban and American clinician-researchers offered a blueprint for future interactions."

11/28/16 - Theresa Reineke Leads Team that Discovers Method to Improve Effectiveness of Orally-Taken Medications
IEM Member Dr. Theresa M. Reineke, Professor of Chemistry, led a team of researchers who, along with colleagues at the Dow Chemical Company, discovered a method of customizing ingredients to make orally-taken medications more dissolvable, and thus absorbed in the bloodstream more quickly and effectively than existing methods. The team tested the process with an anti-seizure drug and another that treats late-stage prostate cancer. Dr. Reineke says that the method could be broadly applied "by many companies to create other life-saving medicines." The research has been published in the American Chemical Society's ACS Central Science and a patent on the technology has been applied for by the University of Minnesota and Dow. The study's Co-Author, Dr. Frank Bates, a University of Minnesota Regents Professor of Chemical Engineering and Materials Science, says that this breakthrough is "a perfect example of what can happen when industry and academia come together."
New Discovery Could Help Oral Medicines Work Better
11/28/16 - Jerrold Vitek Discusses Innovative Deep Brain Stimulation Procedure to Treat Neurological Disorder
IEM Member Dr. Jerrold L. Vitek, McKnight Professor and Chair of the Department of Neurology, discussed in a November 5th Star Tribune article the progress and potential of Deep Brain Stimulation (DBS) to help patients struggling with a variety of neurological disorders, such as Parkinson's Disease (PD). The research uses a method called "closed-loop stimulation" in its DBS procedures, which triggers pulses only when abnormal neural patterns are recognized. This new method also has the potential to reduce post-surgery side effects, such as headaches and dizziness. "This [procedure] has already gone far beyond what anyone thought it could be," said Dr. Vitek. "But we believe that we can fine-tune this even more, so people can have a much better quality of life." Dr. Vitek and his colleagues are also seeking to develop a novel pattern of stimulation called coordinated reset that he says "is a very new and exciting approach." Both closed-loop stimulation and "coordinated reset" "are novel and will provide additional benefits for patients with PD who undergo DBS," says Dr. Vitek.

11/28/16 - Daniel Duprez Discusses Complexity of Relationship Between Diet and Cardiovascular Health
IEM Member Dr. Daniel Duprez, Professor of Medicine, Donald and Patricia Garofalo Chair in Preventive Cardiology, was featured in an article in the October edition of Minnesota Monthly, "Rethinking Conventional Wisdom on Heart Disease." Focusing on research about the relationship between a person's diet and cardiovascular disease, the article described the recent discussion regarding a heart-healthy diet. There are controversial reports that eating more meat and butter would not cause heart disease in everybody. In contrast, studies of the Mediterranean diet have clearly shown that eating more healthy fats from fish, nuts and vegetable oils decreases risk for heart disease. In addition, recent studies show that replacing fats with higher amounts of starches and sugars actually increases the risk of heart disease, which goes against thinking that evolved, in large part, from a study funded by the sugar industry in 1967. "Is it not time to pay more attention what we eat and how we eat, instead of using only drive-in and micro-wave prepared frozen food or canned food with a high sugar drink and dessert? Healthy eating is the corner stone of prevention," says Dr. Duprez.

11/28/16 - Kathryn Cullen Utilizing Brain Imaging to Study Non-Suicidal Self Injury in Adolescent Girls
IEM Member Dr. Kathryn Cullen, Assistant Professor and Division Chief, Child & Adolescent Psychiatry, Department of Psychiatry, and colleagues are beginning a 5-year study that will examine the relationship between self-harm behavior and certain biological metrics, such as hormones and neurocircuitry, in adolescent girls. The number of these non-suicidal self-injury (NSSI) behaviors has been on the rise in recent years, due in part to the diffusion of these behaviors over social media networks. Citing the current lack of data for biological factors as a cause of NSSI behaviors, Dr. Cullen is seeking to find evidence linking the two, stating, "We hope to uncover a meaningful understanding of the neural mechanisms driving NSSI, paving the way for developing new treatments to address NSSI." Besides linking these factors to NSSI, Dr. Cullen hopes that this type of research will help reduce the stigma around mental illness, providing people with a new lens through which they can understand these afflictions.
Emerging Methodology May Improve Mental Health Research
11/28/16 - Alan T. Hirsch & AHA Request CMS Coverage for Supervised Exercise Therapy for Peripheral Artery Disease
IEM Member, Dr. Alan T. Hirsch, Professor of Medicine, Epidemiology and Community Health, Director of the Vascular Medicine Program, and Co-Director of the Minnesota Heart Health Program, on behalf of the American Heart Association (AHA), has requested coverage from the Centers for Medicare and Medicaid (CMS) to provide all Americans with access to supervised exercise therapy as a first line treatment for peripheral artery disease (PAD). For the more than 8 million people who suffer from PAD in the U.S., leg artery blockages lower the flow of oxygenated blood to the legs resulting in muscle fatigue, discomfort and pain during exercise, a symptom called "claudication". People with PAD also face a very high short-term risk of heart attack and stroke.
Currently, claudication is commonly treated via invasive procedures, such as stenting or surgery. However, supervised exercise is now recognized as one of the most safe, effective and inexpensive treatments to improve claudication, in part due to a large NIH-supported trial completed by Dr. Hirsch and other University of Minnesota faculty. The exercise setting also lowers cardiovascular risk. "Stenting and medication will continue to be a common way to treat PAD and these approaches may be preferred by some patients," Dr. Hirsch said. "But now we can offer a program that offers all patients a more therapeutic choice."

10/27/16 - IEM Member & Colleagues Discover Cause of Resistance to Breast Cancer Drug
IEM Member Dr. Douglas Yee, Professor of Medicine and Pharmacology and Director of the Masonic Cancer Center, in collaboration with Reuben S. Harris, Professor of Biochemistry, Molecular Biology and Biophysics, and their colleagues, have identified a protein, APOBEC3B, that creates mutations leading to resistance to the breast cancer drug tamoxifen. As reported in Health Medicine Network, the discovery could lead to improvements that would make tamoxifen more effective in treating breast cancer and also to the treatment of other cancers that become drug-resistant. "In the treatment of all metastatic cancer, patients will eventually develop resistance and progress. What are the mechanisms of resistance? [APOBEC3B] is proving to be a major driver of resistance and something we're continuing to actively investigate," says Dr. Yee. The results have been published in the journal Science Advances.
Culprit Found in Breast Cancer Resistance to Tamoxifen
10/27/16 - FDA Approves New Epilepsy Drug Developed by College of Pharmacy Faculty
IEM Member Dr. James Cloyd, Professor of Experimental and Clinical Pharmacology, and Director of the Center for Orphan Drug Research, and his departmental colleagues, Drs. Angela Birnbaum and Ilo Leppik, have developed a new epilepsy drug product that received FDA approval on October 8. As reported in Epilepsy News Today, the drug, named Carnexiv, can be injected, making it an alternative when patients are unable to take the oral carbamazepine formulations, as may occur when a patient is unconscious or has a severe gastrointestinal disorder. "This approval is the result of years of work to create a novel and stable injection formulation to support patients who need an alternative to oral carbamazepine," says Dr. Cloyd. Carnexiv's development began with NIH funding (Leppik, PI; Cloyd, Co-PI) that resulted in the publication of a pharmacokinetic study. The study laid the groundwork for the design of a Phase II trial that was used as part of the NDA. Development continued through a partnership between the University of Minnesota and a drug company, Lundbeck. A key element in the development plan was submission of an orphan drug designation application (Cloyd co-author) to the FDA, which granted Carnexiv orphan drug status in 2013.

10/27/16 - IEM Members Part of Team that Discovers Role of Endoglin During Embryonic Development of Cardiac & Blood Cells
IEM Members Dr. Rita Perlingeiro, Professor of Medicine/Cardiology, Dr. Daniel J. Garry, Professor of Medicine, and Dr. Naoko Koyano-Nakagawa, Assistant Professor of Medicine/Cardiology, are a part of a team of researchers who discovered the role endoglin plays in the development of the blood and cardiac cells during embryonic development. These researchers and their colleagues manipulated primary heart cells from zebrafish and mice and differentiated mouse pluripotent stem cells to identify the effects of endoglin on cellular expression. Dr. Perlingeiro says that "by using multiple model systems, combined with specialized cell sorting technology and sequencing tools, our findings help uncover mechanisms previously unseen in the few cells engaged in these early development decisions." This research may provide further information in the roles that endoglin plays in congenital heart defects, as well as discovering ways to catalyze the development of blood or heart tissue following an injury.

10/27/16 - IEM Team Begins Researching Application of 3D Printed Scaffold to Treatment of Spinal Cord Injuries
A team of IEM members, Dr. Michael McAlpine, Benjamin Mayhugh Associate Professor in Mechanical Engineering, Dr. James R. Dutton, Research Assistant Professor of Genetics, Cell Biology, and Development at the Minnesota Stem Cell Institute, and Dr. Ann M. Parr, Assistant Professor of Neurosurgery, is working on a new research project that is using 3D printing to construct a scaffold to support cells in the reconstruction of an injured spinal cord. Though in the early stages of development, the team hopes to create a technology that will "provide an effective therapy for spinal cord injury," says Dr. Parr, essentially a "spinal cord on a chip." The scaffold could potentially be used to treat patients with chronic spinal cord injuries and may lead to other advances in the field of regenerative medicine.

10/27/16 - Ben Hackel Close to Commercializing Unique Molecular Imaging Probe for Cancer Detection; MN-REACH Funding Playing Key Role
IEM Member Dr. Benjamin J. Hackel, Assistant Professor of Chemical Engineering and Materials Science, has developed a molecular imaging probe detectable by PET scans for the imaging of numerous types of cancers, including colorectal and breast cancers. As reported in Twin Cities Business, the probe can improve how these cancers are treated. "It's a way of identifying which patients are likely to respond to a particular type of therapy versus patients who aren't likely to respond - it's a personalized medicine approach. Clinics right now don't have a very good way of differentiating between these two patient populations, so we propose that a PET imaging approach would be able to provide that," says Dr. Hackel. MN-REACH funding is being used to complete the final steps toward commercializing the technology, including "making some small but important modifications in the molecule so that it will perform more effectively at the human patient level," according to Dr. Hackel.

10/27/16 - David Jacobs is Lead Author in Study Published in the Journal of Pediatrics on Future Benefits of Healthy Eating by Teens
IEM Member Dr. David R. Jacobs, Professor of Epidemiology & Community Health, was the lead author of a study published in the Journal of Pediatrics showing that healthy eating by teenagers leads to less weight gain and BMI during early adulthood. The study, which followed more than 2,500 students at Minneapolis and St. Paul high schools, from when they were 15 years old until they were 25, showed that the benefits were experienced by not only those who had healthy diets at age 15 but also by those who switched to a healthy diet during those years. Dr. Jacobs concludes that "food preferences and attitudes may be established as early as age 15," and that the "choices adolescents make during that stage establish a lifetime diet pattern, which could influence weight gain over time."
Higher Quality Diet in Adolescence and Dietary Improvements Are Related to Less Weight Gain During the Transition from Adolescence to Adulthood
09/30/16 - Jerry Vitek and Colleagues Awarded $9 Million Udall Center of Excellence in Parkinson's Disease Research
A recently-awarded Udall Center of Excellence in Parkinson's Disease Research at the University of Minnesota will be led by IEM member Dr. Jerrold L. Vitek, Professor and Chair of the Department of Neurology. It is one of 9 such centers funded in the U.S., and will be supported with more than $9 Million of NIH funding over 5 years, with its research theme being "Circuit-based deep brain stimulation for Parkinson's disease." Dr. Vitek, who will serve as the center's Principal Investigator, says that the University of Minnesota has "a world-class multidisciplinary team to treat patients with Parkinson's disease, and because of our significant experience and expertise we are able to take on this complex and often debilitating movement disorder with a goal of improving patient's lives." Legislative support through the MnDRIVE Brain Conditions initiative played a key role in securing the center award for the University, according to Dr. Vitek. Two IEM Seed Group Grants also helped to facilitate the early development of the center's research.

09/30/16 - Wei Chen and Colleagues Awarded $4.4 Million NIH BRAIN Initiative Grant
IEM Executive Committee Member Dr. Wei Chen, Professor of Radiology, and his colleagues were recently awarded a five year, $4.4 Million NIH BRAIN Initiative grant for research entitled "Integrated FMRI Methods to Study Neurophysiology and Circuit Dynamics at Laminar and Columnar Level." According to the project's Public Health Relevance Statement, the research aims to show "how the brain functions at the micro-circuit and network levels," which "should lead to transformative breakthroughs in understanding dynamic functions of the human brain, underlying electrophysiology basis and mapping specificity of fMRI to a new level." In addition, it could potentially lead to the development of leading-edge technology that will make possible more safe and effective deep brain stimulation (DBS) devices for patients. This is the second BRAIN Initiative grant that Dr. Chen received from NIH.

09/30/16 - Jonathan Sachs Published in Nature Chemical Biology
Research conducted by IEM Member Dr. Jonathan N. Sachs, Associate Professor of Biomedical Engineering, entitled "Oxidation increases the strength of the methionine-aromatic interaction," has been published in Nature Chemical Biology. The study, says Dr. Sachs, demonstrates "that oxidation increases the thermodynamic strength of interaction between methionine and aromatic residues," and "that this change is sufficient to block ligand binding in a Tumor Necrosis Factor receptor, and to lead to misfolding in a calcium binding protein involved in cardiac function and heart disease." Dr. Sachs says that this new understanding "will open new avenues of therapeutic design in proteins that are vulnerable to age-related oxidative processes, including neurodegenerative diseases like Parkinson's."

09/30/16 - Bob Tranquillo Leads Team that Developments Grow-Able Synthetic Blood Vessel; Could Eventually Treat Children
A research team led by IEM Member Dr. Robert T. Tranquillo, Professor and Department Head of Biomedical Engineering, has developed an implantable blood vessel that could eventually be used to treat children with heart defects. As reported by the Star Tribune, this vessel is unique because it can continue to grow as the child grows, as it did in growing lambs, which would allow children to avoid having to get it replaced later in life with surgeries that are costly and carry a lot of risk. "For the well-being of the patient, and not to mention the cost involved, there could be really major benefits if this material does in fact grow in a human. We've shown it in a sheep, and we would hope that someday it would also be demonstrated in a patient," says Dr. Tranquillo. The vessel could potentially be used to treat more than 1,000 children in the U.S., annually.

09/30/16 - IEM Group Grant Leads to NIH R01 Grant; Promotes Global Diversity
IEM members Dr. Donald Simone and Dr. Kalpna Gupta received a multi-PI NIH RO1 grant to examine novel targets to treat pain in sickle cell disease. Dr. Simone is a Professor, Department Chair and Division Director, Department of Diagnostic and Biological Sciences and Dr. Gupta is a Professor of Medicine and Co-Chair of the IEM Molecular and Cellular Bioengineering Theme. Dr. Gupta says that the research will address a major co-morbidity associated with sickle cell disease, that affects vast populations globally and mostly African-Americans. "We thank the members for promoting the IEM vision of promoting global diversity. Preliminary data for this grant was supported by an IEM Group grant," says Dr. Gupta.
09/30/16 - Christy Haynes Discusses with Chemical & Engineering News Female Chemistry Faculty Advancements at Top Institutions
IEM Executive Committee Member Dr. Christy L. Haynes, Professor and Vice Chair, Department of Chemistry, discussed with Chemical & Engineering News a recent growth trend in female faculty advancement in chemistry departments at leading Ph.D.-granting institutions in the U.S. While female representation among chemistry faculty grew only 2% to 19.1% from 2013-14 to 2014-15, the increase stands out after years of more incremental increases. Dr. Haynes says that the Open Chemistry Collaborative in Diversity Equity (OXIDE), an initiative supported by the NSF, NIH and DOD, has been working to improve these numbers by getting the leaders of these departments, who are mostly white and male, to drive diversification, instead of placing much of this burden on women and minority Ph.D.'s and faculty. "In bringing all the chairs together, they're trying to make sure that all the work to increase diversity doesn't land on the people that are the diversity," says Dr. Haynes.

09/30/16 - Pierre-Francois Van de Moortele & Thomas Henry Awarded NSF CRCNS Grant
IEM Members Dr. Pierre-Francois Van de Moortele, Associate Professor of Radiology CMRR and Dr. Thomas R. Henry, Professor of Neurology, have been awarded a National Science Foundation Collaborative Research in Computational Neuroscience (CRCNS) grant. Van de Moortele is serving as a PI and Dr. Henry is serving as a Co-PI, for the research, entitled: "US-France Research Proposal. Hippocampal layers: advanced computational anatomy using very high resolution MRI at 7 Tesla in humans." The grant's duration is 3 years and totals $928,000, with the U.S. portion being $573,342.
Dr. Van de Moortele says that this US-France collaborative research combines two powerful, complementary approaches to explore at a sub-millimeter scale tiny inner structures of the hippocampus, and better understand related functions altered in clinical conditions, with a focus on adult and teenager epileptic patients: 1) cutting-edge imaging methods will be pushed on MRI scanners operating at 7 Tesla to attain unprecedented spatial resolution in multi-contrast modalities, and, 2) high-resolution computational anatomy methods, moving beyond traditional morphometry, will be developed to unveil alterations not detected by conventional means. Dr. Van de Moortele and his colleagues expect that the outcome of this research will pave the way for new biomarkers for diagnosis, prognosis and new therapeutic development.

08/29/16 - David Odde and Colleagues Awarded an $8.2 Million NIH Grant for New Cancer Research Center; IEM Seed Grants Played Early Role
IEM Executive Committee Member Dr. David J. Odde, Professor of Biomedical Engineering, and his team, have been awarded a 5-year, $8.2 Million NIH Physical Sciences in Oncology Center (PSOC) grant from the National Cancer Institute. The development of the center project was supported by two IEM Group Grants since 2013. Dr. Odde is serving as the Project Leader (contact PI) for this Center for Modeling Tumor Cell Migration Mechanics, which is one of a nationwide network of 10 PSOC's. In addition to Dr. Odde, other key leaders include IEM Member Dr. David A. Largaespada (multiple PI), Professor, Department of Cell Biology and Development Genetics, of the Masonic Cancer Center, IEM Member Dr. Paolo Provenzano (core PI), Assistant Professor of Biomedical Engineering, and Dr. Steven Rosenfeld (multiple PI), of the Cleveland Clinic. The center will include a team of biomedical engineers, cancer biologists, surgeons and oncologists from the University of Minnesota, who will collaborate with both the Cleveland Clinic and Mayo Clinic.
While common approaches to fighting cancer involve the attacking of cancer cells, the new center will instead explore how cancer cells can be prevented from migrating and ultimately metastasizing and invading vital organs, which are the primary causes of cancer deaths. The center will perform "integrated modeling and experiments to investigate the molecular mechanics of cell migration and how the tumor microenvironment regulates disease progression as a function of the underlying carcinoma genetics."

08/29/16 - Kamil Ugurbil and Essa Yacoub Among Awardees of $6.9 Million in Grants for Continuation of Human Brain Connectivity Research at CMRR
Dr. Kamil Ugurbil, Professor of Medicine, Neurosciences, and Radiology, and Director of the Center for Magnetic Resonance Research (CMRR), and Dr. Essa Yacoub Professor of Radiology in CMRR, both IEM members, have together received two grants totaling $6.9 million, awarded to the CMRR for the continuation of research to map connectivity of the human brain. The research began nearly 5 years ago as a consortium called the Human Connectome Project (HCP), between the University of Minnesota, Washington University in St Louis, and Oxford University (UK), focused on mapping connectivity in the young, healthy adult brain.
This work is now extended to the study of brain connectivity during aging and development with two new grants involving a larger consortium that includes Harvard and UCLA. "The mapping techniques we created in the HCP are truly transformative, allowing us to better understand how the brain is organized and connected. With these new techniques, we are now in a position to ask about how the brain develops and changes over time, and how it is altered in diseases," says Dr. Ugurbil. IEM Member Dr. Essa Yacoub, Professor of Radiology, will co-lead the development component of the research together with Dr. Kathleen Thomas, Professor, Institute of Child Development, in which changes to the behavior, mood and brains of children in their early years of puberty will be measured against changes to their pubescent hormones. Dr. Ugurbil, together with Dr. Melissa Terpstra, Associate Professor of Radiology-CMRR, will lead the effort focused on studying the effects of aging.

08/29/16 - Kevin Peterson to lead $2.6 Million NIH-Funded Study to Improve Diabetes Care
IEM Member Dr. Kevin A. Peterson, Professor of Family Medicine and Community Health and Director, Center for Excellence in Primary Care, will lead a study supported by a $2.6 million grant from the NIH to determine how primary care providers in Minnesota can improve their care of patients with diabetes. As reported in Medical School Blog and EurekaAlert! , the study will be performed by the University of Minnesota in collaboration with Medica and HealthPartners, and determine which primary care delivery models most likely improve clinical outcomes of Minnesota's diabetic patients, by analyzing data from 2008 to 2019. The timing reflects the state's 2008 establishment of health care delivery criteria, which have since been adopted by a majority of Minnesota's primary care practices. The findings can have a nation impact: "If Minnesota legislation has effectively contributed to improving the clinical outcomes of thousands of people with diabetes, it will provide an important example for the rest of the nation for how to approach improving health care," says Dr. Peterson.

08/29/16 - Kalpna Gupta Discusses with KARE 11 Potential Impact of DEA Decision on the Use of Marijuana for Research
IEM Member Dr. Kalpna Gupta, Professor of Medicine and Co-Chair of the IEM Molecular and Cellular Bioengineering Theme, was interviewed by KARE 11 on a recent Drug Enforcement Agency (DEA) decision that could potentially allow for the use of Cannabis for research from additional sources as compared to only one source through NIDA currently. Dr. Gupta and researchers most often use synthetic cannabinoids, not the actual cannabis-derived medications in their pain research, due to existing DEA regulations. The DEA will continue to maintain the Schedule I status for Cannabis derived products but may consider requests for Medical cannabis from different sources. "I'm hoping that this would be the beginning of a conversation," says Dr. Gupta, to ultimately gain access to Minnesota made medical cannabis products.
New DEA Rules for Marijuana Research
08/29/16 - David Jacobs Published in Scientific American with Article on the Positive Impact of Exercise on Cognition
IEM Member Dr. David R. Jacobs, Professor of Epidemiology & Community Health, co-authored an article in Scientific American about how exercise can benefit a person's cognition, both after a workout and in the long-term. While scientists are not entirely certain of how exercise increases brainpower after a workout, one possible reason is that exercise increases the blood flow to the brain and with it, oxygen and other chemicals utilized by the brain. Other possibilities are that exercise creates more mitochondria to generate and sustain brain energy, and that the heart rate increase from exercise increases a person's ability to generate new brain cells. Earlier research performed by Dr. Jacobs showed long-term cognitive benefits of exercise, as 2,747 people between 18 and 30 years of age were followed for 25 years, between 1985 and 2010, with those who were more fit in 1985 performing 10% better in cognitive tests in 2010 than less physically-fit members of their cohort. The conclusion is that regular exercise can benefit a person's cognitive function in the long-term, not just after a workout.

08/29/16 - Colum MacKinnon Conducting Study to Examine Link Between Parkinson's Disease and Sleep Disorder
Dr. Colum MacKinnon, Associate Professor of Neurology, and IEM Member, is researching the link between Parkinson's Disease and muscle activation abnormalities during rapid eye movement (REM) sleep. As reported by Heath Talk , the ultimate objective of Dr. MacKinnon's research is to identify specific aspects of REM sleep that can be predictive of both the onset and progression of Parkinson's Disease, which could lead to earlier diagnosis and treatment of the condition. "The link between REM sleep abnormalities and Parkinson's is probably one of the hottest topics in neurology," says Dr. MacKinnon. Up to 60% of people suffering from Parkinson's experience significant sleep issues, in particular, muscles that should be "turned-off" during REM sleep are instead turned-on. These symptoms are often seen many years before a diagnosis of Parkinson's disease is made and are likely indicative of a "pre-Parkinsonian state." Dr. MacKinnon notes that the University of Minnesota has the "longest history of any institution of following this particular sleep problem," and was the first to make this link. He adds that the Center for Magnetic Resonance Research (CMRR) provides "state-of-art imaging of the brain" that will allow them to assess the changes in brain structure and function that occur as the disease progresses.

08/29/16 - Visible Heart Lab Featured on Big Ten Network and in Medtech Pulse
The Big Ten Network and Medtech Pulse recently featured the IEM-affiliated Visible Heart Lab and video of its various functions, including the reanimation of hearts from both pigs and humans. While the pig heart reanimations occur regularly for educational and research purposes, human heart reanimations occur very infrequently. "On the rare occasion [when] the heart is deemed not viable [for transplant], we get it to the lab within four to six hours," says Dr. Paul A. Iaizzo, Professor of Surgery, Principal Investigator of the Visible Heart Lab and IEM Associate Director for Education and Outreach. Videos and images of the reanimated hearts are placed on the Atlas of Human Cardiac Anatomy, a free website, that had 500,000 users, globally, in 2015. The Visible Heart Lab was started in collaboration with Medtronic, which has also been its primary sponsor.

08/29/16 - Michael Garwood is Member of Team that Developed MRI Technique to Detect Cracks in Teeth
IEM Member Dr. Michael Garwood, Professor of Radiology-CMRR, is among a team of researchers who have developed an MRI-based technique for detecting cracks in teeth called SWeep Imaging with Fourier Transformation (SWIFT). According to Dr. Garwood, "SWIFT is a unique imaging technique because it allows the MRI machine to capture fast-decaying signal from tissue, which is why regular MRI is not able to image bone and teeth." As reported in Health Talk , SWIFT can detect cracks only 20 micrometers wide, approximately the size of two red blood cells. While MRI machines tend to be too costly for dental offices, the technique, and resulting understanding of cracks in teeth, can help to improve current dental care and can also be used to identify ways in which imaging can be improved for dental applications.
Could MRI be Used to Help Detect Cracks in Teeth?

07/27/16 - AIMBE Executive Director Milan Yager to Speak at IEM Seminar on September 13, 2016
The Institute for Engineering in Medicine (IEM) will host a seminar, "The Science Behind Failed Public Policy," by Dr. Milan P. Yager, Executive Director, American Institute for Medical and Biological Engineering (AIMBE) on Tuesday, September 13, 2016 from 12:00pm-1:00pm.
The abstract for Dr. Yager's seminar is as follows: "Today, federal funding for biomedical research, as a percentage of federal spending, has fallen to the lowest level in modern history. For far too many years NIH has been receiving increasing numbers of grant applications and funded fewer and few. What life-saving idea was among the 41,000 grant applications that were not funded last year? The most powerful country in the world, with the strongest economy and the greatest wealth, has made the spending decisions causing Federal research, and specifically, biomedical research, to be nearly flat for over a decade. If the American public recognizes and supports more funding for biomedical research why hasn't Congress responded? If biomedical research has such a high ROI and significant financial return, why isn't America investing more? The reasons behind the failed public policy not to invest in biomedical innovation is actually quite simple. It begins with a story. This discussion of policy and politics might not be what you are expecting. But it surely will impact your research, life, and wellbeing."
07/27/16 - IEM Seed Funding Leads to $3 Million R01 for Brenda Ogle
An IEM Exploratory Grant in 2014 has led to a $3 Million R01 grant for which IEM Member Dr. Brenda A. Ogle, Associate Professor of Biomedical Engineering, is a Principal Investigator. The IEM grant "provided funds to support preliminary experiments that led to the R01 submission," says Dr. Ogle, who is collaborating with former IEM Executive Committee Member Dr. Jianyi Zhang, now Chair of the Department of Biomedical Engineering at the University of Alabama-Birmingham. The R01 grant "Stem Cell Therapy for Myocardial Repair" will explore the use of 3D printing of replacement grafts to repair the heart tissue of patients who have experienced myocardial infarction. Dr. Ogle says that "if successful, 3D printing of cardiac tissues will improve outcomes of acute cardiac injury and will inform prospects for generating intact organs."
07/27/16 - Visible Heart Lab is Stimulating Environment for Students
The IEM-Affiliated Visible Heart Laboratory has evolved into becoming a great place for students to learn about cardiac anatomy and harness the capabilities of 3D printing. As reported by the Minnesota Daily, the lab, which was established in 1997, has been at the forefront of heart research, including the reanimation of human hearts. Approximately 45 students work in the lab, and their enthusiasm for the research creates a very positive work environment. "It's the fun part about the job; it's really working with the young mind and talent; they keep things moving forward," says the Visible Heart Lab's Principal Investigator, Dr. Paul A. Iaizzo, Professor of Surgery and IEM Associate Director for Education and Outreach. More recently, the lab has become one of the 3-D printing hubs for clinical applications at the University of Minnesota. "We scan human hearts with CT and/ MRI and then we can create the digital models," says Dr. Iaizzo. "Once you've created the digital models, you might as well try and print 'em."

07/27/16 - Alan Hirsch Discusses with KARE 11 Campaign for Use of Aspirin to Prevent Heart Attack and Stroke
IEM Member Dr. Alan T. Hirsch, Professor of Medicine, Epidemiology and Community Health, Director of the Vascular Medicine Program and Co-Director of the Minnesota Heart Health Program, discussed with KARE 11, the "Ask about Aspirin" campaign for the prevention of heart attack and stroke. Dr. Hirsch says that, for individuals between the ages of 50 and 69, taking a daily low-dose aspirin can lower the risk of heart attack or stroke by 20%, resulting in as many as 11,000 to 12,000 fewer of these incidents over the lifetime of those who might benefit from the campaign in Minnesota. Dr. Hirsch, noting that aspirin use has both benefit and risk, advises that all individuals know their individual benefit and risk, and first discuss this approach with their primary care physician. "Aspirin is usually safe and effective," says Dr. Hirsch, "but has to be right for the individual. What should you do?: 'Ask about aspirin!'".

07/27/16 - Gwenyth Fischer Discusses Life-Saving Pulse Oximeter Neonatal Screening with Pioneer Press
IEM Member Dr. Gwenyth Fischer, Assistant Professor of Pediatrics, discussed with the Pioneer Press the use of pulse oximeters on newborns to detect potentially life-threatening congenital heart defects so that they can be treated. While the technology has been used in pediatrics for decades, it has more recently become commonplace in the U.S. as a screening tool for congenital heart disease, largely due to the efforts of Minnesotan Annamarie Saarinen, who lobbied the federal government to make pulse oximeter neonatal screening mandatory. Dr. Fischer says that the technology has made a significant impact, as she "can personally attest to several babies caught here with congenital heart disease before they left, potentially saving them from disaster." Ms. Saarinen has since worked with a California-based company to develop a portable and affordable mobile version of the technology to make it viable for screening newborns in developing nations, where its use is being supported by the Newborn Foundation, a St. Paul-based nonprofit founded by Ms. Saarinen.

07/27/16 - Research Team Led by Louis Mansky Makes Significant Discovery about Uniqueness of Retrovirus Structures
A team led by IEM Member Dr. Louis M. Mansky, Professor of Diagnostic & Biological Sciences and Microbiology & Immunology and Director of the Institute for Molecular Virology, has discovered that the structures of retroviruses tend to be distinctive from one another, which has significant implications for future retrovirus research. As reported in Science Daily, Dr. Mansky says "most researchers assume that all retroviruses are just like HIV, but they're not. We cannot take a one-size-fits-all approach when studying retroviruses and discovering new strategies for antiviral treatments or vaccines." Dr. Mansky hopes that the findings will serve as a foundation from which scientists can "determine how to stop these viruses from causing deadly diseases in humans such as cancer and AIDS."

07/27/16 - SpaceX-9 Mission Includes Bruce Hammer's Experiment to Evaluate Accuracy of CMRR Microgravity Simulator
On July 17th, the SpaceX-9 mission successfully launched a rocket toward the International Space Station containing a research experiment from IEM Member Dr. Bruce E. Hammer, Professor of Radiology at the Center for Magnetic Resonance Research (CMRR). As reported in Space Online , the experiment will test the accuracy of a device at the CMRR that simulates microgravity for researching bone loss in space, by evaluating changes in bone cells in the microgravity environment of the low-Earth-orbiting space station. The results will then be matched with those of the same experiments performed at the CMRR, to determine if the simulator's microgravity environment is sufficient for this research. If so, it will provide a ground-based platform to study how simulated microgravity affects cell function. Doing experiments aboard the ISS is difficult due to crew time availability, limited access, cost and logistics required to bring a payload to and from low earth orbit. "When you're doing experiments on Earth that simulate microgravity, you're in a much better-controlled environment," says Dr. Hammer.
06/27/16 - IEM Director Named Recipient of the Prestigious IEEE Biomedical Engineering Award

06/27/16 - Stephen Haines Featured on KSTP for Treatment of Young Patient with Brain Condition
IEM Member Dr. Stephen J. Haines, Professor and Department Head of Neurosurgery, was featured in a KSTP story for his treatment of a patient with Hydrocephalus, referred to as "water on the brain," an incurable condition that affects more than one million Americans. "If for some reason you make more spinal fluid than you absorb back into your blood stream, the fluid will build up and cause increased pressure in the head," says Dr. Haines. His patient, an eight-year-old boy, developed the potentially life-threatening condition following a premature birth. Dr. Haines can treat Hydrocephalus by either popping the membrane that holds the fluid or by installing shunts, and for this patient, he installed two shunts that will connect together and drain the fluid to the child's belly. The patient and his family established a foundation and organized a golf tournament to support Hydrocephalus research and increase awareness of the condition.

06/27/16 - Walter Low & Dan Garry Discuss with BBC & CNN Use of Chimeras for Transplant
IEM Members Dr. Walter C. Low, Professor of Neurosurgery, and Dr. Daniel Garry, Professor of Medicine and Director of the Lillehei Heart Institute, discussed with the BBC and CNN research on the growing of human organs in pigs to be used for transplant, and the issues associated with it. Dr. Low says that the technique could potentially be used to create a number of different types of organs and cells, including pancreas, heart, liver, kidney, lung, cornea, and immune cells; and that "the organs and cells would be exact genetic copies, but much younger and healthier versions, and you would not need to take immunosuppressive drugs which carry side-effects." Dr. Garry states that these personalized humanized organs in gene-edited animals would provide new pre-clinical research models that would be invaluable to study the impact of emerging therapies and disease progression.
However, the NIH has banned funding this research due to concerns of the resulting chimeras developing human cognitive states. Dr. Garry objects to the ban due to its inhibition of medical progress and the creation of a stigma associated with the research. And Dr. Low says that this risk can be avoided. "We can address this issue by examining the brains from each type of chimera that is generated to produce a specific type of organ. For example, if in generating liver chimeras we observe that the pre-term brains also exhibit substantial off-target contribution to areas such as frontal cortex then these fetuses would not be allowed to be born."

06/27/16 - Jakub Tolar Featured in Ottawa Sun for Treatment of Child Suffering from Severe Skin Disease
Dr. Jakub Tolar, Professor of Pediatrics, Director of the Stem Cell Institute and IEM Member, will treat a child from Canada who suffers from Epidermolysis Bullosa (EB), a rare and potentially-fatal skin disease. As reported by the Ottawa Sun, the child, who's nicknamed "Butterfly Boy," will travel to the University of Minnesota to have a blood and bone marrow transplant as part of a clinical trial being led by Dr. Tolar. "The advantage of bone marrow transplant is that you don't just treat a single patch of skin: This is a whole body approach," says Dr. Tolar. While he warns that the treatment doesn't work for all patients, it can have a very positive impact when it does work. "You can go from a kid who is in constant pain, who is wheelchair bound, who has bandages changed for several hours, to someone who goes to school, to the beach, plays in the orchestra, and goes on with his life," says Dr. Tolar.

04/29/16 - 3-D Modeling Plays a Vital Role in TAVR Success; Shows Promise for Wide Range of Medical Procedures
The Laboratory of Dr. Paul A. Iaizzo, Professor of Surgery and IEM Associate Director for Education and Outreach, collaborated with cardiologist Dr. Gregory A. Helmer to generate a 3-D model of a patient's heart to find the optimal size for replacement of her aortic valve. Having the right sized valve was particularly critical to the success of this transcatheter aortic valve replacement (TAVR) procedure performed at the University of Minnesota Medical Center. Such modeling performed by Dr. Iaizzo's team at the IEM-affiliated Visible Heart Lab continues to show the promise for such technologies to improve patient outcomes in a variety of procedures. "We hope that for clinical teams to have such a resource like this at the University will be something that will ultimately improve care delivery," says Dr. Iaizzo.

04/29/16 - Mind-Controlled Drone Race Utilizes Technology First Demonstrated by IEM Director
The University of Florida hosted last weekend what was billed as the first-ever race between mind-controlled drones, utilizing a technology that was first demonstrated at the University of Minnesota in 2013 by Dr. Bin He, Director of IEM and Center for Neuroengineering and Professor of Biomedical Engineering. As reported by the Associated Press, The race, which was held in an indoor basketball court, involved 16 "pilots" who strove to fly a drone through a 10-yard course. Dr. He's group demonstrated in 2013 mind-controlled drone flying in a gym on the campus of the University of Minnesota, which stimulated a number of world-wide efforts on non-medical application of brain-computer interface (BCI). Organizers of the race are seeking to make BCI more mainstream, by having it used for everyday tasks, beyond laboratory settings and medical applications, a future that is becoming more viable as BCI equipment becomes more affordable. "The progress of the BCI field has been faster than I had thought ten years ago. We are getting closer and closer to broad application," says Dr. He.

04/29/16 - Douglas Yee Working to Efficiently Evaluate Breast Cancer Drugs
IEM Member Dr. Douglas Yee, Professor of Medicine and Director of the Masonic Cancer Center, serves on the Executive Committee and is Co-Chair of the Agent Committee of the I-SPY2 clinical trial, which has successfully evaluated several breast cancer drugs simultaneously, with three of those now progressing to the next phase of testing. This approach is unique from that of most clinical trials, in which drugs are tested one at a time, and it saves a lot of time in a process that typically lasts for five or more years for each drug. "To me, it demonstrates that we can identify active agents that are effective in the treatment of breast cancer in a much shorter timeline," says Dr. Yee. The multi-center trial has tested 15 chemotherapy drugs since it began in 2010, and focuses on both the effectiveness of the various drugs as part of a chemotherapy regimen prior to surgery and matched to the molecular profile of a patient's tumor so that the most effective of the drugs can be used for each patient. An arm of the trial is being developed to switch the drug for patients who don't respond sufficiently to their initially matched treatment.
04/29/16 - Roni Evans Discusses Challenge of Studying Chronic Pain's Impact on Young Adults in Story Picked Up by Associated Press
IEM Member Dr. Roni L. Evans, Associate Professor, Center for Spirituality and Healing, recently discussed the challenges of researching chronic pain in young adults with the Minnesota Daily, a story that was reported by the Associated Press and also ran in the Star Tribune and MPR. Chronic pain is reported by approximately one-quarter of people 18 to 29 years of age, and can significantly affect their lives by limiting them from activities they enjoy and isolating them socially. But studying pain in young adults can be challenging due to the subjective nature of measuring it. Dr. Evans says that "You can't see that someone has pain. It's not like a broken leg or a broken arm; it is something that someone experiences, so you really have to rely on what they're telling you...and that makes it hard to study."

04/29/16 - Jeffrey McCullough Discusses Zika Virus in New York Times
Dr. J. Jeffrey McCullough, Professor of Laboratory Medicine and Pathology, American Red Cross Professor of Transfusion Medicine, and IEM Member discussed with the New York Times the logistical challenges of keeping the Zika virus from contaminating blood supplies in effected areas. The FDA approved a new test to screen donated blood, which is needed to avoid the contamination of blood supplies as the virus spreads into the U.S. Without such screening, blood banks in areas most likely to be hit with outbreaks, such as the Gulf Coast states, would have had to import supplies from northern states not yet effected by the virus. "It is logistically difficult, but it can be done," said Dr. McCullough. But the new screening test, which will be initially implemented in Puerto Rico, will help to newly-effected areas to avoid that situation.

03/29/16 - Kelvin Lim Discusses Traumatic Brain Injury's Psychological Impacts and Treatment Strategies
IEM Executive Committee Member Dr. Kelvin O. Lim, Professor and Vice Chair for Research of the Department of Psychiatry, discusses in MinnPost the long-term psychological impact of traumatic brain injury (TBI) and new treatment strategies to address it. TBI, which is often the result of car accidents or combat, can lead to behavioral changes and depression as connections between neurons are damaged, disrupted or disconnected. One of the treatment strategies being explored by Dr. Lim is the mapping of brain-circuit abnormalities and determining whether those can be addressed with transcranial magnetic stimulation (TMS), which will be investigated in a new study conducted at the VA. The effectiveness of TMS and other stimulation techniques to treat TBI is "of great interest to us here at the university," says Dr. Lim.
Psychological Impact of Brain Injury can be Long-Lasting
03/29/16 - FDA Releases New Guidance for Neurological Devices
On March 4th, the FDA released draft guidance on considerations for "Medical devices intended to slow, stop, or reverse the effects of neurological disease face challenges with regard to collecting safety and efficacy data in a clinical study, when less invasive pharmacotherapy approaches may be better understood or more-well accepted in the clinical community." As reported by the Regulatory Affairs Professionals Society, the guidance can apply to devices that treat the progression of neurological diseases, such as Parkinson's, Alzheimer's and primary dystonia. The agency's statement says that "study designs should aim to distinguish between symptomatic benefit(s) and disease-altering benefit(s) that slow disease progression and quantify the magnitude of such benefits in terms of biomarkers and clinical outcome assessments."

03/29/16 - Richard James Proposes Using Twisted X-Rays for Structure Determination
IEM Member Dr. Richard D. James, Professor of Aerospace Engineering and Mechanics, and his colleagues have discovered that twisted X-rays could be used as a better method of performing X-ray crystallography in materials science and biology research. As reported by the International Union of Crystallography, twisted X-rays could better define yet-unknown helical structures than traditional approaches as many of these structures "do not readily crystallize as three-dimensional periodic structures," and the process of crystallization can alter materials. The twisted X-rays could overcome these limitations by "matching the symmetry of the incoming radiation to the symmetry of the structure to be studied." Dr. James says that he and his students are now investigating how to build a source for twisted X-rays, which is challenging because the ability to manipulate X-rays is limited.

03/29/16 - Andrew Grande Treats Painful Nerve Condition with Surgery
IEM Member Dr. Andrew W. Grande, Assistant Professor, Neurosurgery and Co-director of the University of Minnesota's Earl Grande Stroke and Stem Cell Laboratory, performs a surgical procedure to address Trigeminal Neuralgia (TN), a very painful nerve condition. While most of the approximately 150,000 patients diagnosed with TN each year in the U.S. can be treated with medication, some require brain surgery to relieve the pain. One such patient is a mother of four from Hudson, Wisconsin, who's experience with the condition and successful surgery by Dr. Grande are profiled in the Hudson Star- Observer. The surgical procedure, called microvascular decompression, relieves pressure on the trigeminal nerve.

03/29/16 - Emil Lou Discusses Aspirin's Ability to Reduce Cancer Risk
Dr. Emil Lou, Assistant Professor of Medicine and IEM Member, discussed the findings of a recent study published in JAMA Oncology showing that regular use of aspirin can lower a person's cancer risk. As reported by the Academic Health Center's publication Health Talk, the research was based on data from large, decades-long studies of 88,000 women and 47,000 men. The impact was most significant for gastrointestinal cancers, including a 19% reduction for colorectal cancer. Aspirin use to achieve this reduction resulted from taking from .5 to 1.5 tablets per week for a minimum of 6 years. Dr. Lou says that the study "represents one of the most comprehensive studies to date supporting regular aspirin use as a low-cost intervention to help decrease the risk of gastrointestinal cancers."
Benefits of Aspirin May Include Lower Cancer Risk
03/29/16 - IEM Members Offering Cell-Based Therapy Training to University of Minnesota Physicians and Scientists
IEM Executive Committee Member Dr. Allison Hubel, Professor of Mechanical Engineering, and IEM Member David H. McKenna, Jr., Associate Professor of Lab Medicine and Pathology, are directing the Hematology Workforce Training Program, which seeks to directly address the growing need for researchers with cell-based therapy skills. "The ability to treat all of the millions of patients who would benefit from these therapies is limited in part by the lack of trained physicians and scientists in this field," says Dr. Hubel. Funded by an NIH Research Education Program (R25) grant, this short-term training program is customized to a trainee's specific needs and interests and involves both one-month rotations and a research project that are customized to the trainee's career needs. The program is actively recruiting new trainees.

Dr. Paul A. Iaizzo, Professor of Surgery and IEM Associate Director for Education and Outreach, discusses the application of 3-D printing of hearts to surgery, medical device design and education in a recent edition of the Washington Post. The surgical applications include the printing of a model heart prior to surgery to help the patient and family members better understand the situation and provide them with the peace-of-mind that comes from understanding it. "It's powerful and comforting for parents to really understand what the problem is," says Dr. Iaizzo. The educational applications include the use of printed hearts for surgical residents and students in the medical school, which Dr. Iaizzo says "puts that anatomy in the brain in a three-dimensional way that never could have been done another way."

02/29/16 - John Bischof Discusses Organ Preservation in Economist
John C. Bischof, Professor of Mechanical Engineering and IEM Associate Director for Development, has a proposed solution to one of the major challenges of warming cryopreserved organs: heating the tissue quickly and uniformly enough to avoid the damage that would occur from the crystallization or cracking (fracture) that would otherwise occur during the process. Dr. Bischof's approach is to apply tiny (nano) particles of magnetite to the cryoprotectant fluid that bathes the organ, then heat them and the organ by placing the system in a fluctuating magnetic field, an approach he has successfully tested on heart valves and arteries. It is one of several approaches presented in a recent Economist article to allow for the better cooling and warming of organs to achieve the ultimate objective of making many more of them available for transplantation.

02/29/16 - Louis Mansky's Research Could Lead to More Affordable HIV Drugs
IEM Member Dr. Louis M. Mansky, Chair of the Department of Diagnostic and Biological Sciences and Director of the Institute for Molecular Virology, was the lead author of a recent study showing how an RNA-based nucleoside, 5-aza-C, blocked the ability of HIV to spread. As reported in Infection Control Today, this could lead to more affordable HIV medications because RNA-based drugs can be produced in large quantities at a lower cost than most currently available HIV drugs, which are DNA-based. Dr. Mansky says that while 5-aza-C is not as effective at treating HIV as those current drugs,"we can use what we know to try mimicking 5-aza-C to discover new compounds that could be more effective while still being more affordable to produce." The study is being published in the American Society for Microbiology's journal Antimicrobial Agents and Chemotherapy.

02/29/16 - Research by John Osborn Shows that Drug-Resistant High Blood Pressure can be Controlled by Renal Denervation
Dr. John Osborn, Professor of Integrative Biology & Physiology, and IEM Member, was the lead investigator of a study showing that drug-resistant hypertension can be treated by completely ablating nerves to the kidneys. As reported by Medical Xpress, the research shows that arterial blood pressure was lowered when both efferent and afferent nerves between the brain and kidneys were ablated, but not when ablating only the afferent nerves. As a result, Dr. Osborn says that, "Although catheter-based renal nerve ablation is now possible, catheter design needs to be improved since present catheters appear only to partially denervate the kidney. Clearly, it is also important to develop a method to assess the completeness of denervation at the time of the procedure." The research was published in the American Journal of Physiology-Regulatory, Integrative, and Comparative Physiology.

02/29/16 - David Jacobs Conducts Research Showing that Environmental Contaminants in Low Doses Can Harm the Brain
IEM Member Dr. David R. Jacobs, Professor of Epidemiology & Community Health, was among a group of investigators who conducted research showing that persons who are repeatedly exposed to organochlorine pesticides (OCPs), such as DDT, are at greater risk for cognitive impairment. As reported by EurekAlert!, the research included approximately 1,000 individuals at 70 years of age in Uppsala, Sweden. Those with high levels of OCPs in their serum were found to have had three times the risk of future cognitive impairment compared to others who had low levels of the containments. While OCPs were already known to be neurotoxins, the findings are surprising because it shows that even a low level of exposure to OCPs can be harmful if it occurs during a long period of time. The research was published in Environmental International.

02/29/16 - Walter Low and Ann Parr Discuss Relevance of Fetal Tissue to their Research in Treating Parkinson's and Spinal Cord Injury
IEM Members Drs. Walter Low and Ann Parr discuss the importance of fetal tissue to their research in a recent Star Tribune article highlighting the work of several University of Minnesota researchers who are using these types of cells. Walter C. Low, Professor of Neurosurgery, uses them as a positive control against which to assess the effective phenotype of differentiated stem cells from sources other than fetal tissue. "Our goal is to one day take a piece of your skin and make that into a pluripotent stem cell ... that makes dopamine neurons for treating Parkinson's patients," says Dr. Low. A more direct use of fetal tissue stem cells is being explored by Dr. Ann M. Parr, Assistant Professor of Neurosurgery and Director of Spinal Neurosurgery, who is determining whether they can be used to repair damage to the spinal cord. "There are lots and lots of people out there who have chronic spinal cord injury and there is nothing to offer them" says Dr. Parr, who adds "it's the first time this has been a possibility."

01/29/16 - Bob Tranquillo's Pediatric Heart Valve Research Featured on KARE11
The pediatric heart valve development by IEM Member Dr. Robert T. Tranquillo, Professor and Head of the Department of Biomedical Engineering, was recently featured on KARE 11. Dr. Tranquillo is using decellularized tissue tubes grown in the lab from adult skin cells to develop a pediatric heart valve that will grow as the child does, eliminating the need for multiple surgeries, as children outgrow currently-available heart valves. "Our goal is to create an option that requires only one surgery," says Dr. Tranquillo, who has tested the valve in animals and plans to soon approach the FDA about progressing to a human clinical trial for a replacement of the artery in which the valve resides.

01/29/16 - Pediatric Device Innovation Consortium Profiled by Star Tribune
The Pediatric Device Innovation Consortium (PDIC), founded by IEM Member Dr. Gwenyth Fischer, Assistant Professor of Pediatrics, was profiled in the Star Tribune. The PDIC helps to shepherd the development of pediatric devices from their inception to their adoption by industry through grants and guidance to clear the regulatory, reimbursement and other hurdles that typically keep these devices from reaching the patients who need them. "What we'd like to do is take products as far as possible with university help, so that when they exit the university system into industry, they are much more likely to succeed," says Dr. Fischer. The University of Minnesota's Office of Discovery and Translation is providing approximately $250,000 in 2016 to support the PDIC's programs, including planned access to a pediatric device incubator and a program to solicit ideas from parents, in addition to engineers and physicians. The incubation will be done through collaboration with DesignWise Medical, founded by Bradley Slaker, current Innovation Fellow of the IEM-Affiliated Medical Devices Center.

01/29/16 - Enhanced Neuron Imaging Technique Developed by Karen Mesce
IEM Member Dr. Karen A. Mesce, Professor of Neuroscience and Entomology, has developed a novel technique for the imaging of silver or gold-labeled tissue samples in a collaborative effort with colleagues at Agnes Scott College. As reported in the journal eLIFE, the new technique combines spectral confocal microscopy with the metal-staining of neurons. This results in neuronal tissue and cell specimens that are easily imaged in 3D and will allow for the re-imaging of older metal-impregnated samples that have been archived, even as imaging techniques continue to improve in the future. "The progression or stability of cancer or other disease could therefore be charted with accuracy over long periods of time," says Dr. Mesce.

01/29/16 - Valerie Pierre Developing Urinary Tract Infection Diagnostic Tool
IEM Member Dr. Valerie C. Pierre, Associate Professor of Chemistry, is developing a new tool for fast, affordable diagnoses of urinary tract infections (UTIs), which affect nearly half of all women during their lives. Urine cultures have been the most accurate method to diagnose UTI's, but because they typically take 48 to 72 hours, and more urgent treatment is needed, the diagnoses are often based upon symptoms, which are not as reliable. Dr. Pierre's method aims to make a more accurate rapid diagnosis and assess the bacteria's antibiotic resistance to determine the best course of treatment. CTSI provided critical support to Dr. Pierre, including funding, guidance and the facilitation of her collaboration with the Mayo Clinic. A prototype of the tool is being tested on clinical samples and long-term plans include submitting it to the FDA for approval.
