removal of the radial artery for myocardial revascularization: a Doppler study to prevent ischemic complications to the hand. Assessment of the radial artery and hand circulation by computed tomography angiography: a pilot study. According to your study w1x, one of the contraindications for radial artery harvesting is its small inner proximal and distal diameter, smaller than 2 mm (Tables 2 and...

BACKGROUND AND PURPOSE CT angiography (CTA) is widely used and may be the only vascular imaging technique ordered for emergent evaluation of neurovascular disease. With thin-section multisection CTA, the resolution of vessel wall imaging has improved. We describe cases of acute vertebral artery dissection (VAD) in which the only abnormality on CTA was a characteristic thickening of the wall of ...

Unlike the culm hollow structure of most bamboo species, Oxytenanthera abyssinica has a unique solid or semi-solid culm, which may endow it with superior mechanical performance. In this study, variation in fiber morphology and micro-mechanical properties across radial regions was examined by optical microscopy, scanning electron X-ray diffraction, nanoindentation. Results showed that mean value...

 Abstract Castleman disease or giant node hyperplasia is a rare disorder of the lymphoid tissue most often involving the mediastinal lymph nodes. We report a case of localized retroperitoneal hyaline-vascular type of Castleman disease. A 35-year old woman presented with mild epigastric pain with radiation to the back. Amild anemia was the only abnormal associated finding. Abdominal ultrasound a...

ABSTRACT This paper presents an image processing method for information extraction from 3D images of vasculature. It automates the study of vascular structures by extracting quantitative information such as skeleton, length diameter, and vessel-to-tissue ratio for different vessels as well as their branches. Furthermore, it generates 3D visualization of vessels based on desired anatomical chara...

The emergency break-away technology of civil aircraft is particularly important to the safety aircraft, and fuse pin key realization technology. A type pylon was taken as research object. Firstly, finite element structure model established by ABAQUS, explicit dynamic algorithm used study process load pins. Secondly, shear failure test designed verify accuracy model. Finally, influence diameter-...
