Researchers in the Ami Shah Lab study scleroderma and Raynaud’s phenomenon. We examine the rela...tionship between cancer and scleroderma, with a focus on how and if cancer causes scleroderma to develop in some patients. We are currently conducting clinical research to study ways to detect cardiopulmonary complications in patients with scleroderma, biological and imaging markers of Raynaud’s phenomenon, and drugs that improve aspects of scleroderma.view more

We specialize in unconventional, multi-disciplinary approaches to studying the heart at the int...ersection of applied mathematics, physics and computer science. We focus on theory development that leads to new technology and value delivery to the society. Currently we have three research programs:
1. Precision Medicine
To develop a quantitative approach to personalized risk assessment for stroke and dementia based on patent-specific heart anatomy, function and blood flow.
Disciplines: Cardiac Hemodynamics; Medical Imaging Physics; Continuum Mechanics; Computational Fluid Dynamics
2. Information Theory
To quantify and perturb cardiac fibrillation that emerges as a macro-scale behavior of the heart from micro-scale behaviors of inter-dependent components.
Disciplines: Cardiac Electrophysiology; Spiral Wave; Information Theory; Complex Networks
3. Artificial Intelligence
To develop artificial intelligence algorithms to predict the future risk of heart attack, stroke and sudden death, and to assist surgical interventions to prevent these outcomes.

Research in the Biophotonics Imaging Technologies (BIT) Laboratory focuses on developing optica...l imaging and nano-biophotonics technology to reduce the random sampling errors in clinical diagnosis, improve early disease detection and guidance of biopsy and interventions, and improve targeted therapy and monitoring treatment outcomes.
The imaging technologies feature nondestructiveness, unique functional and molecular specificity, and multi-scale resolution (from organ, to architectural morphology, cellular, subcellular and molecular level). The nano-biophotonics technologies emphasize heavily on biocompatibility, multi-function integration and fast track clinical translation. These imaging and nano-biophotonics technologies can also be potentially powerful tools for basic research such as for drug screening, nondestructive assessment of engineered biomaterials in vitro and in vivo, and for studying brain functions on awake animals under normal or controlled social conditions.view more
The Cammarato Lab is located in the Division of Cardiology in the Department of Medicine at the... Johns Hopkins University School of Medicine. We are interested in basic mechanisms of striated muscle biology.
We employ an array of imaging techniques to study “structural physiology” of cardiac and skeletal muscle. Drosophila melanogaster, the fruit fly, expresses both forms of striated muscle and benefits greatly from powerful genetic tools. We investigate conserved myopathic (muscle disease) processes and perform hierarchical and integrative analysis of muscle function from the level of single molecules and macromolecular complexes through the level of the tissue itself.
Anthony Ross Cammarato, MD, is an assistant professor of medicine in the Cardiology Department. He studies the identification and manipulation of age- and mutation-dependent modifiers of cardiac function, hierarchical modeling and imaging of contractile machinery, integrative analysis of striated muscle performance and myopathic processes.view more
The Cardiology Bioengineering Laboratory, located in the Johns Hopkins Hospital, focuses on the... applications of advanced imaging techniques for arrhythmia management. The primary limitation of current fluoroscopy-guided techniques for ablation of cardiac arrhythmia is the inability to visualize soft tissues and 3-dimensional anatomic relationships.
Implementation of alternative advanced modalities has the potential to improve complex ablation procedures by guiding catheter placement, visualizing abnormal scar tissue, reducing procedural time devoted to mapping, and eliminating patient and operator exposure to radiation.
Active projects include
• Physiological differences between isolated hearts in ventricular fibrillation and pulseless electrical activity
• Successful ablation sites in ischemic ventricular tachycardia in a porcine model and the correlation to magnetic resonance imaging (MRI)
• MRI-guided radiofrequency ablation of canine atrial fibrillation, and diagnosis and intervention for arrhythmias
• Physiological and metabolic effects of interruptions in chest compressions during cardiopulmonary resuscitation

Trained technologists assist investigators in the use of these facilities.view more
The CRCIF was established to foster collaborative efforts aimed at elucidating the role of inte...rmediate filaments (IFs) in the heart. Intermediate filaments constitute a class of cytoskeletal proteins in metazoan cells, however, different from actin microfilaments and tubulin microtubules, their function in cardiac cells is poorly understood. Unique from the other two components of the cytoskeleton, IFs are formed by cell type-specific proteins. Desmin is the main component of the IFs in the cardiac myocytes. We measured the consistent induction of desmin post-translational modifications (PTMs, such as phosphorylation, etc.) in various clinical and experimental models of heart failure. Therefore, one of our main focuses is to determine the contribution of desmin PTMs to the development of heart failure in different animal and clinical models.
• Quantification of desmin PTM-forms in different forms of heart failure at the peptide level using mass spectrometry
• Functional assessment of the role of desmin PTMs in heart failure development using single site mutagenesis and biophysical methods
• Molecular characterization of desmin preamyloid oligomers using mass spectrometry, in vitro and in vivo imaging
• Assessment of the diagnostic and pharmacological value of desmin PTMs in heart failure developmentview more

The Dara Kraitchman Laboratory focuses on non-invasive imaging and minimally invasive treatment... of cardiovascular disease. Our laboratory is actively involved in developing new methods to image myocardial function and perfusion using MRI. Current research interests are aimed at determining the optimal timing and method of the administration of mesenchymal stem cells to regenerate infarcted myocardium using non-invasive MR fluoroscopic delivery and imaging. MRI and radiolabeling techniques include novel MR and radiotracer stem cell labeling methods to determine the location, quantity and biodistribution of stem cells after delivery as well as to noninvasively determine the efficacy of these therapies in acute myocardial infarction and peripheral arterial disease.
Our other research focuses on the development of new animal models of human disease for noninvasive imaging studies and the development of promising new therapies in clinical trials for companion animals. view more

Research in the Gregory Kirk Lab examines the natural history of viral infections — particularl...y HIV and hepatitis viruses — in the U.S. and globally. As part of the ALIVE (AIDS Linked to the Intravenous Experience) study, our research looks at a range of pathogenetic, clinical behavioral issues, with a special focus on non-AIDS-related outcomes of HIV, including cancer and liver and lung diseases. We use imaging and clinical, genetic, epigenetic and proteomic methods to identify and learn more about people at greatest risk for clinically relevant outcomes from HIV, hepatitis B and hepatitis C infections. Our long-term goal is to translate our findings into targeted interventions that help reduce the disease burden of these infections.view more
