OBJECTIVE To test the hypothesis that early endoscopic intervention, performed on patients with acute gallstone pancreatitis and biliopancreatic obstruction, reduces systemic and local inflammation. SUMMARY BACKGROUND DATA The role of early endoscopic intervention, in the treatment of acute gallstone pancreatitis, remains controversial. Previous(More)
The ideal arterial graft must share identical functional properties with the host artery. Surgical reconstruction of the common carotid artery (CA) is performed in several clinical situations, using expanded polytetrafluoroethylene prosthesis (ePTFE) or saphenous vein (SV) grafts. At date there is interest in obtaining an arterial graft that improves the(More)

The viscoelastic and inertial properties of the arterial wall are responsible for the arterial functional role in the cardiovascular system. Cryopreservation is widely used to preserve blood vessels for vascular reconstruction but it is controversially suspected to affect the dynamic behaviour of these allografts. The aim of this work was to assess the(More)
A typical engineering approach to developing site-specific design vertical ground motions starts with rock-outcrop horizontal motions, converts them into the vertical component using an empirical vertical-to-horizontal (V/H) ratio for response spectra, and propagates the resulting motion through the soil column as a vertically incident P wave. In the(More)

OBJECTIVE To describe a technical modification that facilitates nephron-sparing surgery (NSS) for renal tumours, without clamping the renal pedicle or promoting renal surface hypothermia. PATIENTS AND METHODS Seventeen patients with renal tumours had NSS using the selective renal-parenchymal clamping technique. In 11 patients the tumour was polar and in(More)
