ROTATIONAL STIFFNESS CAUSED BY PERPENDICULAR COMPRESSION AT SASHIGAMOI JOINTS

Transient rotational compression of the vertebral artery caused by herniated cervical disc. Case report.

Of the many causes of vertebrobasilar insufficiency (VBI), extrinsic compression of the vertebral artery (VA) is relatively uncommon. A syndrome of VBI caused by extrinsic compression of the VA secondary to head rotation has been termed positional vertebrobasilar ischemia. The authors present a case of transient VBI caused by herniation of a cervical disc. Transcranial Doppler ultrasonography w...

Rotational Stiffness at Ridges of Timber Folded-plate Structures

Folded-plate structures provide an efficient design using thin laminated veneer lumber panels. Inspired by Japanese furniture joinery, the multiple tab-and-slot joint was developed for the multi-assembly of timber panels with non-parallel edges without adhesive or metal joints. Because the global analysis of our origami structures reveals that the rotational stiffness at ridges affects the glob...

increased liver stiffness in extrahepatic cholestasis caused by choledocholithiasis

Stiffness of compression devices

The static stiffness index (SSI) is mathematical equation that results in a simple number when the sub-bandage pressure in the supine position is subtracted from the subbandage pressure in the standing weight-bearing position. When SSI data are reported, often a wide range of values is observed for similar materials. The aim of this study was to explore the strength and weakness of the SSI and ...

Increased liver stiffness in extrahepatic cholestasis caused by choledocholithiasis

BACKGROUND Extrahepatic cholestasis that is caused by benign and malignant diseases has been reported to increase liver stiffness (LS), as measured by transient elastography (TE). OBJECTIVES The aim of this study was to evaluate LS in patients with extrahepatic cholestasis due to choledocholithiasis before and after endoscopic sphincterotomy and stone removal. PATIENTS AND METHODS LS was me...
