The primary basic science research interests of our laboratory are in the area of physiological mechanisms of maintaining substrate transport from blood to tissue. This broad topic covers studies on whole animals, such as rats and mice, as well as studies on whole organ, hemorheological, microvascular, cellular, ultrastructural, and molecular levels. The current projects include: 1) control of blood flow and flow distribution in the microcirculation; 2) the effects of synthetic and biologic implants on substrate transport to tissues; 3) the physiological adaptation of the microcirculation and mitochondria to chronic hypoxia, hyperoxia, or cold, and the subsequent alteration in oxygen transport; 4) mathematical modeling of tissue oxygen tension distribution and angiogenesis. 5) tissue engineering; combining isolated cells with biomaterials to form specialized composite structures for implantation, with particular emphasis on endothelial cell physiology and its alteration by isolation and seeding on biomaterials; 6) decreasing the thrombogenicity of synthetic blood vessels and improving their overall performance and biocompatibility; 7) the investigation of tissue damage resulting from abnormal perfusion (e.g., relative ischemia, anoxia, etc.) and therapies which minimize ischemic damage; 8) the abnormal development of tumor microcirculation and its effect on tumor oxygenation; 9) measurement of tissue blood flow and oxygenation as an indicator of tissue viability and functional potential; 10) development of biocompatible materials for soft tissue reconstruction or augmentation; 11) molecular and cellular effects of ultraviolet light on skin which can lead to cancer, and therapies which may minimize damage; 12) wound healing in bone and soft tissues, with special emphasis on the detection and treatment of infection and its effects on healing. 13) improving the outflow facility of ophthalmologic devices implanted to reduce elevated intraocular pressures found in patients with glaucoma. Future studies will continue to focus on improving the biocompatibility of biosynthetic implants.

Cancer diagnostics and therapy:

Joseph Y Lo, Assistant Research Professor of Medical Physics Grad Program, Radiology and Biomedical Engineering
Ph.D., Duke University
The lab focuses on the diagnosis and treatment of cancer using advanced imaging techniques. There are 3 main projects: breast tomosynthesis, computer aided diagnosis, and improved treatment planning for radiation therapy. First, while mammography remains the gold standard in breast cancer screening, it has many well known limitations. Dr. Lo leads a team from the Ravin Advanced Imaging Laboratories (see website above) which collaborates closely with Siemens Healthcare to develop breast tomosynthesis, a form of limited-angle tomography using a modified digital mammography system. Tomosynthesis can acquire a 3D image quickly, easily, and at the same dose as a conventional mammogram. Tomosynthesis will improve sensitivity of breast cancer diagnosis by helping radiologists to detect subtle lesions which would otherwise be obscured. In addition, tomosynthesis will also improve specificity since radiologists can better characterize benign cases and thus avoid unnecessary follow-up imaging studies and surgical procedures. For these reasons, tomosynthesis is the most exciting recent development in breast imaging, and the only technology that can actually replace mammography in the near future. Duke is now conducting clinical trials using the first ever Siemens breast tomosynthesis prototype. Second, for over a decade, we have been a leader in computer aided diagnosis (CAD), which is an interdisciplinary field combining elements of medical physics, engineering, statistics, and bioinformatics. We have developed automated detection algorithms which use computer vision techniques to localize suspicious mammographic lesions. We have also designed predictive models which use machine learning and statistical analysis in order to classify mammograms or sonograms as benign versus malignant. During these studies, we compiled one of the largest multi-institution breast cancer databases with approximately 5000 cases. Finally, we are extending CAD techniques from radiology toward the problem of intensity modulated radiation therapy (IMRT), specifically to improve treatment planning for prostate cancer. Our goal is to improve the efficiency and safety of treatment plans.

Prof. Gauthier is interested in a broad range of topics in the fields of nonlinear and quantum optics, biophysics, and nonlinear dynamical systems.

In the area of optical physics, his group is studying the fundamental characteristics of highly nonlinear light-matter interactions and is using this understanding to develop practical devices. Recently, they have been interested in tailoring the group velocity of laser-driven materials to achieve group velocities that are much greater than or much less than the speed of light in vacuum (so-called fast and slow light). They are measuring the speed at which information travels through fast- and slow-light media to test our understanding of the special theory of relativity, and they are transitioning the slow-light technology to telecommunications applications such as all-optical signal regeneration and processing. Another recent interest is the development of the world's most sensitive all-optical switch. Currently, they have observed switching with an energy density as low as a few hundred yoctoJoules per atomic cross-section, indicating that the switch should be able to operate at the single-photon level.

In the area of biophysics, his group is investigating the electrical activity of the heart from a nonlinear dynamics perspective. It is a multi-disciplinary effort consisting of faculty and students from the departments of Biomedical Engineering, Mathematics, and Physics. They are developing techniques for controlling cardiac dynamics using real-time closed-loop feedback, with the long-term goal of realizing an implantable ultra-low-energy cardiac defibrillator for people at high risk of sudden cardiac death. They are also developing new experimental methods for characterizing the nonlinear response of cardiac tissue and using the resulting data to guide the development of mathematical models for describing the generation and propagation of electrical waves in the heart.

In the area of nonlinear dynamics, his group is interested in the control and synchronization of chaotic devices, especially optical and radio-frequency electronic systems. They are developing new methods for private communication of information using chaotic carriers, using chaotic elements for distance sensing (e.g., low-probability-of-detection radar), using networks of chaotic elements for remote sensing, and using chaotic elements for generating truly random numbers at high data rates.

Injury and Orthopedic Biomechanics:

Laurence N Bohs*, Assistant Research Professor

Jun Chen*, Assistant Research Professor
Cells of the immature nucleus pulposus (NP) are biologically active and may play an important role in regulating matrix biosynthesis during intervertebral disc (IVD) development and aging. The immature NP contains a large amount of notochordal cells that disappear with aging. Preliminary results suggest that cells derived from the notochordal cell-containing NP do not respond to physical stimuli and soluble mediators in the same manner as cells from the neighboring anulus fibrosus. These differences for the immature NP may be mediated by different receptor-matrix interactions that may be important in regulating the onset and progression of IVD aging and degeneration. We have recently developed a fluorescence-activated cell sorting (FACS) protocol that identifies a population of notochordal-like NP cells with a unique molecular phenotype (i.e. unique integrin and mRNA expression pattern) distinct from that of smaller cells within the NP. We propose that cell-matrix interactions in the NP may be altered upon aging of this subpopulation of cells, a change that may contribute to decreases in cellularity and metabolism associated with IVD degeneration. The central hypothesis is that a change in the notochordal cell population with aging is associated with a dramatic alteration in the distribution of secreted proteins and cell surface receptors within the NP that regulates cell-matrix interactions and responses to environmental stimuli.

There are several research projects underway in my laboratory, focusing on the improvement of diagnostic accuracy in digital chest radiography and digital mammography. The first project uses a dual-energy digital radiography technique that forms images which have either the bones or soft-tissues canceled. By eliminating the ribs in the soft-tissue image, better accuracy in detecting nodules has been demonstrated in early clinical evaluations of the technique. The bone image is also useful in that it demonstrates whether a detected nodule is calcified, at a fraction of the cost and radiation exposure of sending the patient to CT. We have received six years of NIH grant funding to develop a practical screening method for nodular disease using the dual-energy technique. A second major area of research is digital tomosynthesis. This technique allows longitudinal slice images of a patient to be generated from a series of projection images taken at different angles. We are evaluating this technique for its potential to improve detection of pulmonary nodules. We have received seven years of NIH funding to develop and evaluate this technique. Preliminary evaluation in a pilot study using human subjects revealed that the detection rate for pulmonary nodules increased from about 22% to 70% in tomosynthesis slice images compared with conventional PA chest radiographs. Thus, the tomosynthesis technique would appear to hold promise as a method of improving both sensitivity and specificity of pulmonary nodule detection in vivo. We are also expanding this tomosynthesis work to evaluate its potential for improving detection of masses and calcifications in digital mammograms. Other projects include theoretical analysis of digital imaging performance and the measurement of image quality (DQE) in computed radiography and flat-panel systems.

I have spent the last thirty one years engaged in building and applying advanced imaging technologies ranging from work on the first CT scanner installed at Duke (1974) to installation of the world's first high filed (1.5 T) clinical MRI system (1983). I continue to serve the medical center in commissioning new imaging technologies. Since 1983 my research has focused on extending the resolution of magnetic resonance imaging from the clinical domain, typically with voxels of 1 x 1 x 1 mm to the microscopic domain required for basic research in small animal models with voxels 125,000X smaller. The Center for In Vivo Microscopy was founded in 1985 and continues today with generous support from the National Center for Research Resources (P41 RR005959). The Center currently supports 6 state-of-the-art imaging systems for small animal imaging: 3 MRI systems (2, 7, and 9.4 T), a micro x-ray system, a micro- CT system, and a microPET system. The Center has embarked on an aggressive program to expand these modalities into molecular imaging with support from NCI (R24 CA092656)

This broad topic covers studies on whole animals, such as rats and mice, as well as studies on whole organ, hemorheological, microvascular, cellular, ultrastructural, and molecular levels. The current projects include: 1) control of blood flow and flow distribution in the microcirculation; 2) the effects of synthetic and biologic implants on substrate transport to tissues; 3) the physiological adaptation of the microcirculation and mitochondria to chronic hypoxia, hyperoxia, or cold, and the subsequent alteration in oxygen transport; 4) mathematical modeling of tissue oxygen tension distribution and angiogenesis. 5) tissue engineering; combining isolated cells with biomaterials to form specialized composite structures for implantation, with particular emphasis on endothelial cell physiology and its alteration by isolation and seeding on biomaterials; 6) decreasing the thrombogenicity of synthetic blood vessels and improving their overall performance and biocompatibility; 7) the investigation of tissue damage resulting from abnormal perfusion (e.g., relative ischemia, anoxia, etc.) and therapies which minimize ischemic damage; 8) the abnormal development of tumor microcirculation and its effect on tumor oxygenation; 9) measurement of tissue blood flow and oxygenation as an indicator of tissue viability and functional potential; 10) development of biocompatible materials for soft tissue reconstruction or augmentation; 11) molecular and cellular effects of ultraviolet light on skin which can lead to cancer, and therapies which may minimize damage; 12) wound healing in bone and soft tissues, with special emphasis on the detection and treatment of infection and its effects on healing. 13) improving the outflow facility of ophthalmologic devices implanted to reduce elevated intraocular pressures found in patients with glaucoma. Future studies will continue to focus on improving the biocompatibility of biosynthetic implants. Additional new emphasis may be placed on investigating the effects of radiation on wound healing and methods of minimizing the consequences of radiation exposure.

Jun Chen, Assistant Research Professor
Cells of the immature nucleus pulposus (NP) are biologically active and may play an important role in regulating matrix biosynthesis during intervertebral disc (IVD) development and aging. The immature NP contains a large amount of notochordal cells that disappear with aging. Preliminary results suggest that cells derived from the notochordal cell-containing NP do not respond to physical stimuli and soluble mediators in the same manner as cells from the neighboring anulus fibrosus. These differences for the immature NP may be mediated by different receptor-matrix interactions that may be important in regulating the onset and progression of IVD aging and degeneration. We have recently developed a fluorescence-activated cell sorting (FACS) protocol that identifies a population of notochordal-like NP cells with a unique molecular phenotype (i.e. unique integrin and mRNA expression pattern) distinct from that of smaller cells within the NP. We propose that cell-matrix interactions in the NP may be altered upon aging of this subpopulation of cells, a change that may contribute to decreases in cellularity and metabolism associated with IVD degeneration. The central hypothesis is that a change in the notochordal cell population with aging is associated with a dramatic alteration in the distribution of secreted proteins and cell surface receptors within the NP that regulates cell-matrix interactions and responses to environmental stimuli.
