UNLABELLED Liver regeneration is of major clinical importance in the setting of liver injury, resection, and transplantation. A20, a potent antiinflammatory and nuclear factor kappa B (NF-κB) inhibitory protein, has established pro-proliferative properties in hepatocytes, in part through decreasing expression of the cyclin dependent kinase inhibitor, p21.(More)
In Switzerland 278 diabetic men and 256 women in the age group 35 to 54 were examined for the presence of angiopathic lesions, according to a standardized protocol of a multinational study comprising 6,695 diabetics from 14 countries. The diabetics were distributed according to sex, age, and duration of the disease into groups of equal size.(More)
BACKGROUND Accelerated atherosclerosis is the leading cause of morbidity and mortality in diabetic patients. Hyperglycemia is a recognized independent risk factor for heightened atherogenesis in diabetes mellitus (DM). However, our understanding of the mechanisms underlying glucose damage to the vasculature remains incomplete. METHODOLOGY/PRINCIPAL(More)
The aim of this study was to review our experience with laparoscopic end colostomy closure. A retrospective review of a prospectively entered database was performed. Proportions and continuous variables were compared using the Fisher's exact and the Mann-Whitney U tests, respectively. Within the study period, 53 patients underwent closure of end(More)
In the development of microsurgical mouse models of hepatic regeneration and repair, lobe-specific regenerative responses were observed. We therefore determined the hepatic regenerative capacity of individual mouse liver lobes. In mice, 26, 60, 75, and 83% of total liver mass was resected. Bromo-deoxyuridine (BrdU) was injected prior to liver harvest and(More)
INTRODUCTION Aspiration pneumonia in hospitalized surgical patients has been associated with a mortality of approximately 30%. The aim of this study was to assess pre-, intra- and postoperative risk factors for mortality in patients suffering aspiration pneumonia after abdominal surgery. METHODS Retrospective study from 01/2006-12/2012 of patients with(More)
A technique was developed to permit estimation of intravenous glucose tolerance and the concomitant immunoreactive insulin (IRI) response in the Geneva colony of the semi-desert rodentAcomys cahirinus. Following intravenous injection of glucose 1.5 g/kg, youngAcomys (2–3 months, 25–35 g body weight) had a significantly lower glucose tolerance (p<0.01) and a(More)

PURPOSE OF REVIEW The surgical procedure remains the key element in the multidisciplinary treatment of a wide variety of degenerative, traumatic, tumorous, congenital, and vascular diseases, resulting in an estimated 234 million surgical interventions worldwide each year. Undesired effects are inherent in any medical intervention, but are of particular(More)
Acute mesenteric ischemia (AMI) is an emergency with a mortality rate up to 50 %. Detecting AMI continues to be a major challenge. This study assed the correlation of repeated preoperative serum lactate with bowel necrosis and to identify risk factors for a lethal outcome in patients with AMI. A retrospective study of 91 patients with clinically and(More)
