  • The coagulation and fibrinolytic systems are central to the hemostatic mechanism, which works promptly on vascular injury and tissue damage. The rapid response is generated by specific molecular interactions between components in these systems. Thus, the regulation mechanism of the sys-tems is programmed in each component, as exemplified by the elegant pro-cesses in zymogen activation.

  • Under the Clean Air Act, particulate matter (PM) is one of the major air pollutants for which National Ambient Air Quality Standards (NAAQS) are to be established on the basis of the scientific evidence on risks to human health. The U.S. Environmental Protection Agency (EPA), other federal and state government agencies, and nongovernment organizations are conducting a major multiyear research effort to improve scientific understanding of airborne PM and its effects on human health.

  • Coronary heart disease is the leading cause of death worldwide, and 3.8 million men and 3.4 million women die of the disease each year. After an acute myocardial infarction, early and successful myocardial reperfusion with the use of thrombolytic therapy or primary percutaneous coronary intervention (PCI) is the most effective strategy for reducing the size of a myocardial infarct and improving the clinical outcome. The process of restoring blood flow to the ischemic myocardium, however, can induce injury.

  • Tendons are known to have a profound impact on the overall function of the musculoskeletal system in their role as a structural link and force transmitter between muscle and bone. Their unique viscoelastic response under tension allows efficient use and recycling of stored energy during stretch involved in locomotion, modulating joint position control, and providing protection from muscle injuries through reduction of mechanical oscillation and shock.

  • The field of biomechanics has been evolving from the times of ancient Greeks. Recent publications and research in biomechanics sky rocketed as the field of traditional biomechanics is creating new opportunities in diagnostics, therapy, rehabilitation, motion preservation, kinesiology, total joint replacement, biomechanics of living systems at small scale, and other areas.

  • A truly distributed service would allow a client to use services by connecting to a broker nearest to the client’s geographical location. By having such local broker, a client does not have to re-connect all the way back to the broker that it was last attached to. If the client is not satisfied with the response times that it experiences or if the broker that it has connected to fails, the client could very well choose to connect to some other local broker.

  • Effective new treatments of heart disease are based on a refined understanding of cellular function and the heart's response to environmental stresses. Not surprisingly therefore, the field of experimental cardiology has experienced a phase of rapid exponential growth during the last decade. The acquisition of new knowledge has been so fast that textbooks of cardiology or textbooks of cardiovascular physiology are often hard-pressed to keep up with the most important conceptual advances.

  • The primary role of tendon is to transmit the force of its associated muscle to bone. As such, the tendon needs to be relatively stiff and strong under tension. Herzog (2007) have stated that mechanical properties, such as fiber-bundle organization of the tendon allow for the maintenance of high tensile strength, with considerable flexibility in bending, in the same way that a wire rope maintains high tensile strength and flexibility as compared to an equal cross-section of solid steel (e.g., Alexander (1988a); Alexander (1988b) and Wainwright et al. (1982)).

  • In the kidney, the Th2-mediated response is characterized by formation of immune complexes and deposition in the glomerulus, which is usually followed by complement activation. On the other hand, the Th1-mediated response is characterized by infiltration of circulating mononuclear cells and crescent formation. Both responses are capable of releasing mediators that are responsible for functional and structural changes as seen in primary glomerular diseases.

  • Motor vehicle crashes remain the number one cause of death in the United States among young people. In 2003, the Insurance Institute for Highway Safety reported, “motor vehicle crashes still cause about 1 of every 3 injury deaths among children. Among those 4-12 years old, crash injuries are the leading cause of death. Most of the deaths are passenger vehicle occupants, and proper restraint use can reduce these fatalities.

  • While various glomerular disorders account for the most cases of end stage renal failure, the etio-pathogenesis of these conditions intrigued many investigators for decades. A clear knowledge of the etiology and pathogenesis is crucial for developing novel strategies to prevent and to treat these disorders. Notwithstanding the continuous emergence of new discoveries, we still have a long way to get any closer to a thorough understanding of the mechanisms of glomerular injury.

  • Our panel attempted to develop guidelines that would meet the needs of a person with recent onset spinal cord injury who is in respiratory distress. This document represents the best recommendations that we could provide given the availability of scientific evidence. As chairman of the panel writing these guidelines, my goal was to gather and disseminate the best available knowledge and information about managing the respiratory needs of patients with ventilation problems.
