The National Institute on Aging (NIA), the lead institute within the NIH for Alzheimer’s research, recently announced the award. “We already know that exercise is good for the body, but this study will tell us whether it is also good for the brain, particularly in people with mild memory problems who are at risk of developing dementia,” Baker says.

Donald W. Bowden, PhD
The long-term focus of Dr. Bowden’s research has been the genetic analysis of diabetes, especially type 2 diabetes (non-insulin dependent diabetes mellitus, adult onset diabetes), and complications of diabetes such as diabetic nephropathy and cardiovascular disease.  Projects range from a focused molecular genetic effort to identify diabetes genes in a small region of chromosome 20 q12-q13.1, to the evaluation of whether genes contribute to the development of cardiovascular and cerebrovascular disease in people with type 2 diabetes.  Sophisticated clinical methods are used to quantify cardiovascular disease (e.g., radiological measurement of coronary calcified plaque) and cerebrovascular disease (magnetic resonance imaging). Additional research information.

K. Bridget Brosnihan, PhD, MS
Dr. Brosnihan is a Professor in the Hypertension and Vascular Research Center in the Division of Surgical Sciences and holds joint-appointments in the Department of Physiology and Pharmacology, the section of Molecular Medicine of Internal Medicine, Regenerative Medicine, and the Department of Obstetrics and Gynecology.  She is co-Director of the Molecular Medicine and Translational Science Graduate Program.  She is the Director of the Biochemistry Core for the Hypertension and Vascular Disease Center.  She has been certified since 1996 as a High Complexity Director of Clinical Laboratories by the American Board of Bioanalysis. 
   Her academic qualifications reflect a professional trajectory characterized by novel and significant contributions to the understanding of the neuro-hormonal mechanisms participating in the regulation of cardiovascular function and the role that estrogen plays in the modulation of neural and hormonal mechanisms regulating arterial pressure.  Dr. Brosnihan has been a major contributor to the co-discovery of angiotensin-(1-7) [Ang-(1-7)], a novel peptide of the renin angiotensin system that opposes the actions of Ang II.  Her studies were responsible for the original demonstration that Ang-(1-7) acts as a powerful vasodilator of the coronary circulation through the release of nitric oxide.  Dr. Brosnihan initiated a novel and highly productive effort on the role of estrogen in the regulation of the activity of angiotensin converting enzyme and angiotensin peptides, studies which began to unravel the mechanisms by which estrogen influences blood pressure and displays vasculo-protective functions.  This has led to her describing the role of Ang-(1-7) in pregnancy and preeclampsia.  

Candice M. Brown, PhD
The goal of Dr. Brown's research is to identify the molecular mechanisms underlying sex differences in the brain's response to acute systemic inflammation. Her study uses a cecal ligation and puncture (CLP) mouse model of sepsis combined with gonadectomy and estradiol replacement to address their research questions. One of their current studies addresses whether estradiol and its classical receptors, estrogen receptor-a (ERa) and ERb, suppress brain-microvascular proinflammato ry responses during early sepsis, and limit immunosuppressive responses in late sepsis to accelerate a return to homeostasis. To accomplish this, they employ cellular and molecular approaches combined with intravital microscopy (IVM) and dynamic contrast enhanced MR imaging (DCE-MRI).  The combination of IVM and DCE-MRI allows them to quantify estradiol-mediated longitudinal changes in leukocyte adhesion, endothelial permeability, and vascular density within the CNS over the course of acute systemic inflammation. This project is funded by NINDS.


Jonathan H. Burdette, MD
Dr. Burdette’s current research focuses on using advanced MR imaging techniques to study the brain as a complex network.  He is a founding member of the Laboratory for Complex Brain Networks (LCBN), in which diffusion tensor imaging, perfusion imaging, voxel-based morphometry, and functional MRI (fMRI) are employed to study brain networks using network theory approaches.  Such approaches analyze the entire brain and view brain processing as a complex system rather than just analyzing small portions of the brain.  He is applying these techniques to learn how exercise, nutritional habits, and meditation affect functioning of the brain in the elderly.

His studies' most recent and exciting results indicate that dietary soy supplementation may decrease estrogen-induced cell proliferation and cancer risk in the breast and uterus. See additional information.

Robert C. Coghill, PhD
The capacity to monitor the integrity of our bodies and to be made immediately aware of injury through the experience of pain is critical for our survival. However, the central nervous system mechanisms that translate information about tissue damage into the conscious experience of pain remain poorly understood. Thus, the central objective of Dr. Coghihll's research is to better characterize fundamental aspects of pain processing mechanisms of the brain.  Most studies within his laboratory employ both psychophysical and functional magnetic resonance imaging (fMRI) techniques to explore the relationship between regional brain activation and discrete aspects of the pain experience.  Additional research information.

Jay R. Kaplan, MD 
Dr. Kaplan is Professor of Pathology (Comparative Medicine), Translational Science, and Anthropology. He also serves as Head of the Section on Comparative Medicine (Department of Pathology) and Director of the Wake Forest Primate Center. He moved to the Wake Forest University School of Medicine in 1979 to study the effects of behavioral stress on susceptibility and resistance to coronary artery atherosclerosis in a monkey model of human heart disease. His current research with monkeys focuses on the behavioral and genetic factors that influence the quality of premenopausal ovarian function, and in turn, on the effect of ovarian function on risk for chronic disease, including coronary heart disease and osteoporosis. This research has demonstrated that much of the postmenopausal trajectory for atherosclerosis and bone loss is established premenopausally, suggesting that primary prevention of postmenopausal disease should begin in the decades prior to menopause. Dr. Kaplan is a member of the National Scientific Advisory Board for the California National Primate Research Center and has been invited to be a member of the Society for Women’s Health Research Interdisciplinary Studies in Sex Differences (ISIS) Fund for Cardiovascular Disease Network. He helped initiate and is deeply involved in the collaboration between the Indonesian Primate Research Center (Pusat Studi Satwa Primata), an activity that has been ongoing for 25 years and that has resulted in the training of numerous Indonesian scientists and veterinarians. Dr. Kaplan has had a long and successful career in scientific outreach, helping bring together investigators and suitable animal models.  Additional information.

T. Michael D. O'Shea, MD, MPH
Dr. O'Shea is the co-PI for the Extremely Low Gestational Age Newborn (ELGAN) Study. This cohort study began in 2002 with funding from the National Institute of Neurological Disorders and Stroke. A cohort of 1500 babies born before the third trimester of pregnancy were recruited and over 1200 survived neonatal intensive care and have been followed since that time. In the first 5-year funding interval, information was collected about initiators of inflammation, levels of inflammation-related proteins in blood, brain ultrasonography, and neurological and developmental testing. We learned that children who had signs of inflammation in their blood were more likely to have development problems when they were 2 years old. In the second funding period, the cohort is being evaluated when the children are 9-10 years old. Evaluations include neuropsychological assessment, academic achievement testing, and assessment for epilepsy and autism spectrum disorders. Of these children, 220 will undergo brain MRI. The study will be completed in the fall of 2015. More information is available at The Elgan Research Study website.

Lawrence L. Rudel, PhD
Research into the causes of premature coronary heart disease has been the focus of the work in Dr. Rudel's laboratory for over 30 years. Nonhuman primate models of diet-induced atherosclerosis have been studied, and nutritional components of the diet including cholesterol and individual types of fatty acids have been evaluated. Cholesterol, saturated fatty acids and monounsaturated fatty acids have been found to be proatherogenic while polyunsaturated fatty acids have been found to be antiatherogenic. By delineating molecular aspects of diet responsiveness of cholesterol and lipoprotein metabolism in a nonhuman primate model of coronary artery atherosclerosis, Dr. Rudel's team is providing information that can eventually be helpful in the development of strategies for prevention of coronary heart disease. See more information, and additional details.

Carol A. Shively, PhD
Current areas of research for Dr. Shively include social inequalities in health, and modeling the comorbidity of coronary heart disease and depression in a primate model.  Social inequalties in health are widely recognized to contribute to the global burden of disease.  Understanding how low social status is translated into illness is a critical topic of research. Two diseases inversely related to social status in human beings are coronary heart disease (CHD) and depressive disorders.  Depression and CHD are highly comorbid in the human population.  CHD patients who experience depression after their first myocardial infarction (heart attack) are 4-6 times more likely to die of a second heart attack in the next 18 months.  The mechanisms underlying this comorbidity are poorly understood.  Her research group is currently studying this comorbidity in monkeys, and will treat depression pharmacologically to determine whether that improves CHD risk.  See more information.

Beth Paterson Smith, PhD
Dr. Smith's main area of research interest involves the use of chemodenervation to manage various orthopaedic conditions. Since 1988, she has been collaborating with L. Andrew Koman, MD to evaluate the safety and efficacy of intramuscular injections of botulinum toxin in the management of muscle spasticity associated with pediatric cerebral palsy.

Joel Douglas Stitzel, Jr., PhD
A Professor of Biomedical Engineering, Dr. Stitzel's current research interests involve crash injury research and engineering biomechanics of trauma, automotive safety, and sports and military biomechanics. A major project he has been involved in is the creation of a new generation of human body models to represent live humans with precision and detail not known in research "dummies" before. The models will contain detailed representation of the bones and soft tissues of the human body, with special attention to those parts that are frequently injured in vehicle collisions. They are expected to provide researchers with crucial knowledge needed to better predict the effect of different degrees of force and locations of impact on the body during an automobile crash than they have been able to do with traditional crash test dummies.

Charles H. Tegeler IV, MD
In addition to conducting research on migraine headaches using Brainwave Optimization™, a non-invasive technology that helps the brain achieve balance in neural oscillations, Dr. Tegeler and his team will expand their prior work on migraines and insomnia, while adding research projects on mild cognitive impairment (MCI), and traumatic brain injury (TBI). “We are on the way toward finding safe, effective, non-invasive solutions for the management or prevention of these important clinical disorders.” See additional information.

Jeffrey S. Willey, PhD
Dr. Willey's laboratory investigates skeletal tissue degradation resulting from both long-duration spaceflight and radiation therapy.  The link between these conditions is radiation exposure, which astronauts will face from solar and galactic sources.  The lab's current project with CBI is assessing degradation in the knee joints of rats following modeled spaceflight conditions, using 7 Tesla microMRI, histology, and mechanical testing.  The effects of unloading and radiation on knee joint structures in the spaceflight environment are undefined.  Knee joint tissues, including articular cartilage, menisci, and ligaments are all crucial for proper joint function and stability. Thus, degradation of the joint during spaceflight may elevate the risk of bone fracture and arthritis either during spaceflight or following the return to Earth.  The study's goal is to prevent this degradation with approved countermeasures for skeletal degradation during spaceflight, including exercise and select therapeutics.  These approaches may then be applied to their ongoing studies examining bone and joint degradation after cancer therapy.

The figure below represents 7T microMRI images of rat knees, one year after a single exposure to 0, 1, and 5 Gray of X-rays.  The plots represent the T2 relaxation times from the articular cartilage lining of the joint.  The shift toward higher relaxation times in the cartilage after irradiation is indicative of cartilage damage, specifically degradation of collagen within the matrix.
