The complex of the translocase mitochondrial outer membrane (TOM), mediates recognition, unfolding, and translocation of preproteins. We have used a combination of biochemical and electrophysiological methods to study the properties of the preprotein-conducting pore of the purified TOM complex. The pore is cation-selective and voltage-gated. It shows three(More)
BACKGROUND Thirty-three patients were candidates for laparoscopic choledochotomy. The indications for this operation are described. METHODS The procedure was completed 32 times (97%). We had 29 successful common bile duct (CBD) clearances, three negative explorations, and one failed clearance which needed to be converted to laparotomy. All the completed(More)
Data concerning 6,865 laparocholecystectomies have been collected retrospectively from 19 Italian groups. Only 5% of all patients were chosen for open cholecystectomy (OC). Acute cholecystitis was present in 5.6% of laparocholecystectomies (LC). Conversion to laparotomy occurred in 3.1% of patients. Mortality was 0.06%, morbidity 2.53% (general anesthesia(More)
Simplified parietal cell vagotomies (Taylor's and Hill-Barker's procedures) were proposed more than a decade ago to make the operation easier and faster. Efficacy and safety have proven to be as good as with proximal gastric vagotomy. The Hill-Barker operation is particularly simplified by the laparoscopic approach, which enables the procedure to be(More)
Lead, cadmium and mercury are non-essential heavy metals that may interfere with biological systems, exhibiting high toxicity to human and marine biota. Due to bioaccumulation of heavy metals in the food chain, seafood may concentrate high levels of these contaminants since they are often at the top of aquatic food chain. In this study, 342 seafood samples,(More)
On account of dissatisfaction with the two-staged approach to stones in the common bile duct, and the risks associated with endoscopic papillotomy, one-stage laparoscopic duct exploration was commenced. The initial experienced with 20 cases is presented. In 13 cases the transcystic approach to the main duct was not successful, so a choledochotomy was(More)
