Airway biology

The Airway Biology Laboratory studies signal transduction mechanisms that regulate the structure and function of airway smooth muscle during development and in adulthood. The major focus is on mechanisms that regulate smooth muscle contractility and their role in clinically relevant problems such as asthma and airway inflammation.

The long-term goal of these studies is to help formulate more-effective and safer therapies for use in the operating room and intensive care medicine — both important areas for supporting the war fighter — that will alleviate symptoms of bronchospasm and bronchoconstriction.

Altitude physiology

Mayo Clinic has placed strong emphasis on the study of altitude physiology through its involvement in the U.S. Antarctic Program, which has a large number of healthy people going to the South Pole through the sea-level McMurdo Station each spring and summer.

Although the altitudes are not extreme, most personnel will have mild to moderate altitude-related symptoms. The frequency, intensity and duration of symptoms have not been formally quantified previously in the U.S. Antarctic Program.

Of particular relevance to the Department of Defense: The highly structured Antarctic program offers a unique opportunity to study predictors of altitude illness in an otherwise healthy population that cannot be easily pursued at other locations.

Biomechanics and motion analysis

Mayo Clinic conducts a wide range of studies in the Biomechanics Laboratory that examine joint and soft tissue mechanics. Studies characterize tissue properties, assess devices and surgical procedure outcomes, and make use of both standard and custom-made testing equipment. Kai-Nan An, Ph.D., of Mayo Clinic in Rochester, Minn., directs the Biomechanics Laboratory.

Two particular areas of focus in the laboratory relevant to Department of Defense interests are:

  • Developing novel protocols for biomechanical research using medical imaging technology, such as fluoroscopy, ultrasound, CT and MRI
  • Investigating the influence of mechanical stimulus on cell function and organization in tissue (mechanobiology), which will facilitate the future success of tissue engineering

Mayo also studies direct motion treatment options in its Motion Analysis Laboratory. Directed by Kenton R. Kaufman, Ph.D., of Mayo Clinic in Rochester, Minn., the Motion Analysis Laboratory offers state-of-the-art treatment planning for patients with movement difficulties, aids in documenting results of therapeutic procedures and conducts research on future clinical applications of human movement analysis.

Modern motion analysis techniques, such as those used in the Motion Analysis Laboratory, can evaluate all aspects of a patient's gait at one time, allowing simultaneous treatment of as many issues as possible.

A key benefit of motion analysis is improved clinical decision-making. Using objective data gathered in the Motion Analysis Laboratory, clinicians can determine the most appropriate surgery or other treatment to correct each person's gait issue or other movement disorder. Depending on the condition, several surgical and nonsurgical therapies may be considered.

The team also helps wounded veterans with lower-limb prostheses improve their lives by focusing on rehabilitative training methods. The technologies and techniques developed for military personnel who have lost their legs in battle easily transfers to civilian need as well.

Human integrative physiology

Mayo Clinic's Human Integrative and Environmental Physiology Laboratory and Clinical Pharmacology Laboratory are studying how the peripheral circulation and autonomic reflexes adapt to physical stresses such as standing, exercising or body heating — all areas of importance to the active war fighter.

In many of these studies, researchers use both invasive and noninvasive techniques to measure blood flow in human volunteers. The subjects then engage in activities (for example, exercise) that evoke physiological responses, and researchers infuse agonist and antagonist drugs to understand the mechanisms that govern the responses.

Areas of interest include:

  • Blood flow to exercising muscles
  • Skin blood flow responses to heating
  • Physiological responses to orthostatic stress
  • The autonomic nervous system and its receptors
  • Physiological responses to bariatric surgery
  • Pharmacological agents relevant to anesthesia

Infection and immunity

The research program in infection and immunity at Mayo Clinic is aimed at understanding host-pathogen interaction and improving the management of various infectious diseases, with a major focus on orthopedic and transplant-related infections. Both are key areas of value to the Department of Defense, especially orthopedics.

The research approach stretches from bench to bedside, leading to valuable deliverables — products that can serve patients today. The Infection and Immunity Laboratory achieves these goals by focusing on three areas:

  • Laboratory-based projects aimed at understanding the interaction between the human host and the invading microbe
  • Translational research projects that apply laboratory data to the clinical arena
  • Clinical projects to assess the state of clinical practice and generate relevant questions that need further laboratory-based investigations

Infectious diseases

Translational research is the hallmark of infectious diseases research at Mayo Clinic with a goal of delivering new and effective care quickly and efficiently. Work over the past 50-plus years has led to numerous diagnostics, infection control tools, and novel drugs and therapeutics.

It is not unusual for basic research discoveries to be immediately translated into a change in clinical approach, and many achievements have led to direct deliverables supportive of the war fighter in the field or in the hospital.

Investigators and clinicians collaborate to conduct clinical trials that provide patients with access to novel, experimental diagnostics and therapies for life-threatening infections. Investigations include emerging pathogens, novel diagnostic and therapeutic approaches, gene therapy, antimicrobial resistance, and counterbioterrorism, such as the rapid test for anthrax.

Infectious disease investigators conduct in vitro and in vivo studies of new anti-microbics, study novel patterns and mechanisms of antimicrobial resistance, track emerging pathogens, and develop unique antimicrobial therapies. Methods include culture, molecular techniques and animal models.

Lung defense, infection and fibrosis

Mayo Clinic is placing special emphasis on lung defense. One focus in the Lung Defense, Infection and Fibrosis Laboratory is to better understand lung defense as it relates to infection in immunocompromised hosts.

The lab has been very engaged in understanding the life cycle and mechanisms by which Pneumocystis carinii infects immunocompromised individuals. Recent studies have led to new insights for modulating immunity as well as for discovering new drug targets for this important opportunistic infection.

A second concern is to better understand mechanisms of lung fibrosis in the idiopathic interstitial pneumonias. The idiopathic interstitial pneumonias are diseases without known causes that slowly lead to the replacement of the lung with scar material. The lab has focused upon the role of two important cytokines, including transforming growth factor-beta and tumor necrosis factor-alpha.

Through a combination of cell studies and animal modeling, the lab is aiming to develop new modalities to treat patients with these important lung diseases.

Magnetic resonance imaging

Mayo's program in magnetic resonance imaging is leading the nation in expanding the range of tissue, organ and system characteristics that can be noninvasively evaluated with MRI techniques. These studies include several areas of potential interest to the Department of Defense: investigation of new methods for high-resolution MRI of moving structures, techniques of ultrafast MRI and methods for noninvasive mapping of the vascular system, especially the coronary arteries.

Studies of the basic physics of motion effects in the magnetic resonance data acquisition process have led to the development of "navigator echo" and "autocorrection" imaging techniques that are highly suited for resolving structures that are in motion. Other studies employ MRI to quantitatively assess vascular flow characteristics such as velocity, volumetric rates, and disordered flow or turbulence.

Research is directed at developing novel magnetic resonance techniques to probe bone trabecular morphology, measure cellular organization in space and noninvasively delineate the mechanical properties of the tissue.
