Abstract Blunt carotid artery injuries occur in 0.3% of blunt injured patients and maylead to devastating neurological consequences. However, arterial mechanics leading to internallayer subfailure have not been quantified. Twenty-two human carotid artery segments and 18 porcinethoracic aorta segments were opened to expose the intimal side and longitudinally distracted tofailure. (more…)

Abstract Airway smooth muscle cells exhibit stiffening during contractile activation.This stiffening may be interpreted as a result of the stabilizing influence of the mechanicalprestress stored within the cytoskeleton (CSK). However, in vivo, airway smooth muscle cellscontract while simultaneously experiencing breathing-induced stretching. Excessive stretching ofcells could cause actin-myosin crosslinks, and possibly other cytoskeletal filaments, (more…)

Abstract Print and broadcast journalists follow a general set of guidelines in deciding what to report. This article shows how you can increase your chances of drawing media attention simply by understanding and using the system. A fictional certifid personal trainer with a new business called Train with Wayne manages to catch the eye of the media. (more…)

Abstract Mechanical conditioning represents a potential means to enhance thebiochemical and biomechanical properties of tissue engineered vascular grafts (TEVGs). (more…)

Abstract Many athletes do not know the importance of hearty eating to achieve their maximum performance. Add to this gastrointestinal problems that many experience, and the outcome is likely to be a diet with not enough of the right foods at the right time (more…)

Abstract Highly soluble gases exchange primarily with the bronchial circulationthrough pulmonary airway tissue. Because of this airway exchange, the assumption that end-exhaledalcohol concentration (EEAC) is equal to alveolar alcohol concentration (AAC) cannot be true. Duringexhalation, (more…)

Abstract Vertebral fractures due to osteoporosis commonly occur under non-traumaticloading conditions. This problem affects more than 1 in 3 women and 1 in 10 men over a lifetime.Measurement of bone mineral density (BMD) has traditionally been used as a method for diagnosis ofvertebral osteoporosis. However, this method does not fully account for the influence of changes inthe trabecular bone quality, such as micro-architecture, tissue properties and levels ofmicrodamage, on the strength of the vertebra. Studies have shown that deterioration of the vertebraltrabecular architecture results in a more anisotropic structure which has a greater susceptibilityto fracture. (more…)
