background : since risk factors of hypertension are formed during adolescent period and regarding that attitudes change occurs more easily in these ages, the present paper aimed to evaluate the impact of education based on the theory of planned behavior in hypertension prevention behaviors in female adolescent students. methods : in this quasi-experimental study, 160 girls of 12-16 yr old (80 i...

Thoracic endovascular aortic repair (TEVAR) has evolved into an established treatment option for type B aortic dissection (TBAD) since it was first introduced 2 decades ago. Morbidity and mortality have decreased due to the minimally invasive character of TEVAR, with adequate stabilization of the dissection, restoration of true lumen perfusion, and subsequent positive aortic remodeling. However...

A regular office chair was equipped with force transducers, which allow to monitor and to guide the sitting behavior of a person during an office working day. Only four force transducers are required to estimate characteristic parameters for quantifying the biomechanical effect of a certain sitting posture. Based on these parameters, which rely on a simple biomechnical model, a posture cost fun...

Emerging bio-microfluidic systems are embracing electroosmosis mechanisms to supervise ionised physiological fluids. Impelled by the exploration of electro-micro-pumping in bio-engineering domains, present inquisition, a research policy associated with hemodynamical deportment blood circulation under suspension gold and alumina nanoparticles diverging fatty artery subject electro-osmotic drivin...

To clarify which hemodynamic measurement correlates best with lung mechanics in infants with congenital heart disease and left-to-right shunts, dynamic pulmonary function tests and echocardiography were performed in 26 infants with such disease (study infants) and in 37 normal, healthy infants (control infants). The tidal volume and pulmonary compliance (CL) were lower and airway resistance hig...

Carotid atherosclerotic plaques are a major cause of ischaemic stroke. The biomechanical environment to which the arterial wall and plaque is subjected to plays an important role in the initiation, progression and rupture of carotid plaques. MRI is frequently used to characterize the morphology of a carotid plaque, but new developments in MRI enable more functional assessment of carotid plaques...

Finite element simulations of stent deployment were carried out by considering the intrinsic anisotropic behaviour, described by a Holzapfel-Gasser-Ogden (HGO) hyperelastic anisotropic model, of individual artery layers. The model parameters were calibrated against the experimental stress-stretch responses in both circumferential and longitudinal directions. The results showed that stent expans...

Numerical models represent a powerful tool for investigating the biomechanical behavior of articular cartilages, in particular in the case of complex conformation of anatomical site. In the literature, there are complex non-linear-multiphase models for investigating the mechanical response of articular cartilages, but seldom implemented for the analysis of high organized structure such as the f...

1. Abstract Time requirements for the solving of complex large-scale engineering problems can be substantially reduced by using parallel computation. Motivated by a computationally demanding biomechanical system identification problem, we introduce a parallel implementation of a stochastic population based global optimizer, the Particle Swarm Algorithm as a means of obtaining increased computat...
