The pharmacological properties of the alpha(2)-adrenergic receptors regulating the release of norepinephrine were investigated in human neocortex. Slices were preincubated with [(3)H]norepinephrine, superfused under blockade of transmitter reuptake, and stimulated electrically. First, the autoinhibitory circuit of [(3)H]norepinephrine release was analyzed(More)
OBJECTIVE Interleukin-18 (IL-18) is a potent proinflammatory cytokine whose role in human obesity has recently been suggested. The aim of our study was to analyse in morbidly obese patients undergoing gastric bypass, the relationship of IL-18 with insulin resistance and with proinflammatory cytokines (tumour necrosis factor-alpha receptors, sTNFR),(More)
To elucidate the mechanism of action of the anticonvulsant gabapentin (GBP), we compared its effects on K+-evoked [3H]-noradrenaline ([3H]-NA) release from rat hippocampal and human neocortical slices with those of the KATP channel opener pinacidil and the Na+ channel blockers phenytoin, carbamazepine and lamotrigine. Rat hippocampal and human neocortical(More)
BACKGROUND Arterial reconstruction is essential in liver transplantation. In some patients there may be an inadequate flow as a result of stenosis, intimal dissection, or anomalies of the hepatic artery. METHODS This study analyzes our experience with 23 patients in whom arterial anastomosis was performed using the splenic artery due to the inadequacy of(More)
To determine if ischemic conditioning of the stomach improves the morbidity, mortality, and the anastomotic failure in gastroplasties with cervical anastomosis. Analysis of all patients with indication for cervical gastroplasty during the period of study. In all cases, ischemic conditioning was performed by selective embolization. Anastomotic failure,(More)
BACKGROUND Modern management of Oesophageal and oesophagogastric junction (OGJ) cancers requires a multidisciplinary approach, which was implemented at our health centre in 2005. This study aimed to assess the impact of this change on clinical outcomes. METHODS A retrospective cohort study was conducted, covering all patients treated for oesophageal and(More)
PURPOSE The outcome of patients with upper gastrointestinal hemorrhage is greatly influenced by recurrence of bleeding, but it may be possible to identify patients who have a low risk for rebleeding, and can be discharged after a short hospitalization. To examine the effect of an early discharge protocol (length of hospital stay < or =3 days), we conducted(More)
