Intravascular ultrasound may be useful for studying the natural history of atherosclerotic lesions of different morphologies and for guiding interventional strategies. This study was designed to test the hypothesis that tissue appearance by intravascular ultrasound is related to the biomechanical properties of atheroma components. Forty-three atheroma caps were obtained from the abdominal aorta...

conclusions according to the results of the study, health-promoting model-based self-care behaviors can help identify and predict cardiac surgery patients’ lifestyles in iran. this pattern can be used as a framework for discharge planning and the implementation of educational interventions to improve the lifestyles of cabg patients. background advances in coronary artery surgery have reduced pa...

encouraging an active lifestyle is an essential part of successful rehabilitation programs, and the link between physical activity and quality of life (qol) is well established among patients with mobility disorders. biomechanical aspects of wheelchair design play an important role in physical activity and social participation of disabled individuals. this review focuses on key biomechanical fe...

: investigating the mechanical behaviour of a healthy human ankle shows that it can be simulated by a mechanism composed of simple elements such as spring, and actuator. hence, appropriate design of this mechanism can be resulted to an artificial ankle that can help amputees properly. researches show that whatever the biomechanical behaviour of artificial ankle is similar to that of natural ank...

  This study was designed to elucidate the possible difference between supa and ethicon.nylon in suturing rat skin.75 female spragne-dawley albino rats with mean weight 250 g were used and randomly divided into three groups of 30,30 and 15 rats.in 60 rats anesthesea was induced by ketamin and xylazin.followed by surgical preparation , a 5 cm abdominal skin incision was made and sutured by simp...

Ventilator settings resulting in decreased driving pressure (ΔP) are positively associated with survival. How to further foster the potential beneficial mediator effect of a reduced ΔP? One possibility is promoting the active modification of the lung's "mechanical scenario" by means of lung recruitment and positive end-expiratory pressure selection. By taking into account the individual distrib...
