Cell growth is closely related to cell proliferation and an adequate ribosome biogenesis appears to be necessary for cell duplication. In the present study, we have investigated the relationship between rRNA synthesis and cell cycle progression. For this purpose, in a first set of experiments, we evaluated the effect of rRNA synthesis variation on cycle(More)
Cirrhotic patients who need critical care support show high morbidity and mortality rates compared with other critically ill patients. Their prognosis is, in fact, influenced by both the severity of the underlying hepatic disease and the worsening of extrahepatic organ function. Clinicians and investigators have been persistently looking for objective(More)
AIM This study aims to evaluate the management of intensive care beds according to the demands received by the SUEM 118 of Padua. It has been carried out by examining the reports drawn up by SUEM physicians from October 1996 to December 2001. The study rated the number of patients for whom an admission to the Intensive Care Unit (ICU) was required,(More)
Human intestinal infections by Shiga toxin (Stx)-producing Escherichia coli cause hemorrhagic colitis and hemolytic uremic syndrome (HUS), which represents the main cause of acute renal failure in early childhood. In HUS, Stx released in the gut enter the bloodstream and are targeted to renal endothelium. The mechanism of toxin delivery is still a matter of(More)
The endothelial damage induced by Stx represents the main pathogenic event in the HUS associated with STEC infections in humans. Stx, released in the gut by bacteria, enter the bloodstream and are targeted to renal endothelia. The role of PMN as a toxin carrier has been the object of controversy. In this paper, we confirm the binding of Stx1 to PMN, also(More)
Blood loss during liver transplantation (OLTx) is a common consequence of pre-existing abnormalities of the hemostatic system, portal hypertension with multiple collateral vessels, portal vein thrombosis, previous abdominal surgery, splenomegaly, and poor "functional" recovery of the new liver. The intrinsic coagulopathic features of end stage cirrhosis(More)
The poor clinical conditions associated with end-stage cirrhosis, pre-existing pulmonary abnormalities, and high comorbidity rates in patients with high Model for End-Stage Liver Disease scores are all well-recognized factors that increase the risk of pulmonary complications after orthotopic liver transplantation (OLT) surgery. Many intraoperative and(More)
BACKGROUND In our study, we evaluated the analgesic effect and plasma level time course of subanesthetic doses of intraoperative S(+)-ketamine administered by continuous epidural infusion for postthoracotomic pain. METHODS A study population of 140 patients undergoing thoracic surgery was randomly assigned to either S(+)-ketamine or ropivacaine by(More)
INTRODUCTION Claims for tooth damage following intubation are increasing. An anaesthetic chart (AC) has been proposed to describe patient's pre-existent dental diseases and any possible lesions caused during intubation and extubation. MATERIALS AND METHODS We conducted a retrospective study of 235 cases of dental lesions reported in litigation files from(More)
