Skeletal muscle weakness is frequently associated with stiffness changes [1,2], which may alter functional contraction and passive elongation dynamics. Cine Phase Contrast (CPC) MRI has been successfully used to quantify skeletal muscle strain distribution in a single plane [3,4]. The strain distribution was found to be non-uniform, indicating complex internal dynamics of skeletal muscle. The o...

Higher levels of habitual physical activity favorably impact on arterial stiffness. It is not clear, however, whether lifetime habitual physical activities of different intensities carry the same protective effect and to what extent any such effect is mediated by other biological cardiovascular risk factors. We, therefore, examined longitudinal data on habitual physical activity and cardiovascu...

we present a 23-year-old man with distal humerus osteoid osteoma referring to our hospital with pain and progressive stiffness. the patient has been suffering from the disease for two years without a certain diagnosis. the radiographies of elbow did not reveal the pathology but further ct scan and mri studies demonstrated the tumor. the en block resection of the tumor resolved the pain immediat...

The purpose of this study is to demonstrate a new MRI compatible loading device capable of reconstructing realistic loading scenarios of the human foot for research in the field of foot biomechanics. This device has two different configurations: one used to compress the forefoot and one to bend the metatarsophalangeal joints. Required plantar pressure distribution under the metatarsal heads can...

PURPOSE This in vitro study determined the stress distribution around an implant placed in a posterior edentulous maxillary model with simulated sinus grafts that had different degrees of stiffness. MATERIALS AND METHODS The composite photoelastic model with a standard threaded implant consisted of simulated crestal cortical, cancellous, sinus cortical, and grafted bone. The graft maturation ...

A vast majority of natural or synthetic materials are characterized by their anisotropic properties, such as stiffness. Such anisotropy is effected by the spatial distribution of the fine-scale structure and/or anisotropy of the constituent phases at a finer scale. In design, proper control of the anisotropymay greatly enhance the efficiency and performance of synthesized structures. We propose...

BACKGROUND Increased arterial stiffness is a cardiovascular outcome of metabolic syndrome (MetS). The chromosome 9p21 locus has been identified as a major locus for risk of coronary artery disease (CAD). The single nucleotide polymorphism (SNP), rs1333049 on chromosome 9p21.3 has been strongly associated with CAD and myocardial infarction. Increased arterial stiffness could be the link between ...

AIMS Relationship between obesity and cardiovascular (CV) disease depends not only on the amount of body fat, but also on its distribution. For example, individuals with increased fat accumulation in the abdominal region have atherogenic lipid profiles and are at increased CV risk. The loss of elasticity in medium and large arteries is an early manifestation of atherosclerosis. The aim of this ...
