Background: Portal flow diversion by portacaval shunts (PCS) has been shown to prevent primary graft nonfunction in liver transplantation using small-for-size grafts. In this study, we examine whether PCS can improve reperfusion injury after major hepatectomy in pigs.
Materials And Methods: In 14 pigs, a partial PCS was constructed following 65% hepatectomy and 1 h of inflow ischemia.
Background: Numerous previous studies have established the hepatoprotective properties of N-acetylcysteine (NAC). The present study was designed to investigate the effects of NAC on a warm hepatic ischemia-reperfusion rat model with a focus on the role of cAMP.
Materials And Methods: Fifty-six male Wistar rats were allocated randomly into the control group (n = 28) or the study group (group NAC, n = 28).
Background And Objective: An effort has been made to distinguish the composition of carotid atherosclerotic plaques (CAP) from patients undergoing carotid endarterectomy, by laser induced fluorescence spectroscopy.
Study Design/materials And Methods: Different excitation wavelengths were used: 476, 488, and 458 nm of a continuous wave krypton/argon ion laser, and 337 nm of a pulsed nitrogen laser. Twenty-three CAP samples from different patients were investigated and several spectra from each plaque were obtained.
Background: Gangliocytic paraganglioma of the duodenum is a peculiar neuroendocrine tumor, often revealed as an incidental radiographic finding or as a result of gastrointestinal hemorrhage, due to frequent ulceration of the overlying mucosa. Most lesions are pedunculated and submucosal with distinctive histology, consisting of endocrine, ganglion and spindle-shaped Schwann cells.
Methods: A case of a duodenal gangliocytic paraganglioma is reported in a 50-year-old woman presenting with episodes of melena.
