background nonalcoholic fatty liver disease (nafld) is being increasingly recognized as a cause of chronic liver disease. it has also been associated with devastating outcomes such as decompensated liver cirrhosis and hepatocellular carcinoma, as well as diabetes and metabolic syndrome. objectives this study was conducted in order to assess liver fibrosis using fibroscan, and to compare these r...

conclusions the pattern of longitudinally increased liver stiffness measurements efficiently supported clinical decisions for individualized management strategies. repeated transient elastography in real-life clinical practice appears to have a practical role in monitoring liver transplanted patients. background liver transplanted patients need close surveillance for early signs of graft diseas...

In this report four previously unpublished notes, concerned with aeroelastic effects on a particular slender delta aircraft configuration, are collected together. Some general flutter calculations show that decreasing stiffness leads to instability in the aircraft short period mode whilst the higher frequency modes remain stable. The reasons for the instability and the implications regarding ai...

Because wrist rotation dynamics are dominated by stiffness (Charles SK, Hogan N. J Biomech 44: 614-621, 2011), understanding how humans plan and execute coordinated wrist rotations requires knowledge of the stiffness characteristics of the wrist joint. In the past, the passive stiffness of the wrist joint has been measured in 1 degree of freedom (DOF). Although these 1-DOF measurements inform u...

Brillouin microscopy is a new tool to characterize the stiffness of cells and tissues, however the underlying relationship between stiffness and Brillouin measurements remains unknown. As the stiffness of biological materials is influenced by hydration, we performed Brillouin microscopy on hydrogels whilst independently examining the role of stiffness and water content. Brillouin measurements w...

Vascular stiffness is an indicator of cardiovascular health, with carotid artery stiffness having established correlation to coronary heart disease and utility in cardiovascular diagnosis and screening. State of art equipment for stiffness evaluation are expensive, require expertise to operate and not amenable for field deployment. In this context, we developed ARTerial Stiffness Evaluation for...

Background Arterial (aortic) stiffness is a well-recognized pathophysiological change that plays a significant role in the determination of risk factors for various cardiovascular diseases [1]. Measurement of arterial stiffness using pulse wave velocity (PWV) is the gold standard among non-invasive modalities. Recently, a novel non-invasive MRI based technique known as magnetic resonance elasto...

The ability to predict load-bearing capacity during the consolidation phase in distraction osteogenesis by non-invasive means would represent a significant advance in the management of patients undergoing such treatment. Measurements of stiffness have been suggested as a promising tool for this purpose. Although the multidimensional characteristics of bone loading in compression, bending and to...

BACKGROUND Liver transplanted patients need close surveillance for early signs of graft disease. OBJECTIVES Transient elastography can safely be repeated over time, offering serial liver stiffness measurement values. Serial stiffness measurements were compared to single baseline stiffness measurements in predicting the appearance of liver-related clinical events and guiding subsequent clinica...
