1Water and Heavy Metal Transport in Roadside Soils显示文摘Roads with very high traffic loads in regions where soils are low in both pH and sorption capacity might be a source of percolation water loaded with heavy metals. Looking at some 'worst case' scenarios, this study focused on the input of traffic related pollutants and on Pb, Cd, Cu, Zn, Ni and Cr concentrations in the soil matrix and soil solution, respectively. The analysis also included pH and electrical conductivity and at some sites DOC. The investigations were carried out on sandy soils with more or less low pH values at four motorway sites in Germany. The average of daily traffic was about 50 000 up to 90 000 vehicles. Soil pore water was collected in two soil depths and at four distances from the road. The pH in general decreased with increasing distance from the roadside. The elevated pH near the roadside was presumably caused by deposition of dust and weathering residues of the road asphalt, as well as by infiltration of salt that was used during winter time. At these road sites, increased heavy metal concentrations in the soil matrix as well as in the soil solution were found. However, the concentrations seldom exceeded reference values of the German Soil Protection Act. The soil solution concentrations tended to increase from the road edge to 10 m distance, whereas the concentration in the soil matrix decreased. Elevated DOC concentrations corresponded with elevated Cu concentrations but did not substantially change this tendency. High soil water percolation rates were found near the roads. Thus, even low metal concentrations of percolation water could yield high metal loads in a narrow area beside the road.B. KOCHER G. WESSOLEK H. STOFFREGEN 2005Pedosphere2005,15,6:25

4Risk-adjustment in hepatobiliarypancreatic surgery显示文摘AIM: The present study evaluates the performance of the POSSUM, the American Society of Anesthetists (ASA),APACHE and Childs classification in predicting mortality and morbidity in hepatopancreaticobiliary (HPB) surgery.We describe especially the limitations and advantages of risk in stratifying the patients.METHODS: We investigated 177 randomly chosen patients undergoing eledive complex HPB surgery in a single institution with a total of 71 pre-operative and intra-operative risk factors.Primary endpoint was in-hospital mortality and morbidity.Ordered logistic regression analysis was used to identify individual predictors of operative morbidity and mortality.RESULTS: The operative mortality in the series was 3.95% .This compared well with the p-POSSUM and APACHE predicted mortality of 4.31% and 4.29% respectively. Postoperative complications amounted to 45% with 24 (13.6%)patients having a major adverse event. On multivariate analysis the pre-operative POSSUM physiological score (OR = 1.18,P = 0.009) was superior in predicting complications compared to the ASA (P = 0.108), APACHE (P = 0.117)or Childs classification (P = 0.136). In addition, serum sodium, creatinine, international normalized ratio (INR),pulse rate, and intra-operative blood loss were independent risk factors. A combination of the POSSUM variables and INR offered the optimal combination of risk factors for risk prognostication in HPB surgery.CONCLUSION: Morbidity for elective HPB surgery can be accurately predicted and applied in everyday surgical practice as an adjunct in the process of informed consent and for effective allocation of resources for intensive and high-dependency care facilities.Hemant M Kocher Paris P Tekkis Palepu Gopal Ameet G Patel Simon Cottam Irving S Benjamin 2005World Journal of Gastroenterology2005,11,16:3

13AIF-regulated oxidative phosphorylation supports lung cancer development显示文摘Cancer is a major and still increasing cause of death in humans. Most cancer cells have a fundamentally different metabolic profile from that of normal tissue. This shift away from mitochondrial ATP synthesis via oxidative phosphorylation towards a high rate of glycolysis, termed Warburg effect, has long been recognized as a paradigmatic hallmark of cancer, supporting the increased biosynthetic demands of tumor cells. Here we show that deletion of apoptosis-inducing factor (AIF) in a Kras^G12D-driven mouse lung cancer model resulted in a marked survival advantage, with delayed tumor onset and decreased malignant progression. Mechanistically, Aif deletion leads to oxidative phosphorylation (OXPHOS) deficiency and a switch in cellular metabolism towards glycolysis in non-transformed pneumocytes and at early stages of tumor development. Paradoxically, although Aif-deficient cells exhibited a metabolic Warburg profile, this bioenergetic change resulted in a growth disadvantage of Kras^G12D-driven as well as Kras wild-type lung cancer cells. Cell-autonomous re-expression of both wild-type and mutant AIF (displaying an intact mitochondrial, but abrogated apoptotic function) in Aif-knockout Kras^G12D mice restored OXPHOS and reduced animal survival to the same level as AIF wild-type mice. In patients with non-small cell lung cancer, high AIF expression was associated with poor prognosis. These data show that AIF-regulated mitochondrial respiration and OXPHOS drive the progression of lung cancer.Shuan Rao Laura Mondragon Blanka Pranjic Toshikatsu Hanada Gautier Stoll Thomas Kocher Peng Zhang Alexander Jais Alexander Lercher Andreas Bergthaler Daniel Schramek Katharina Haigh Valentina Sica Marion Leduc Nazanine Modjtahedi Tsung-Pin Pai Masahiro Onji Iris Uribesalgo Reiko Hanada Ivona Kozieradzki Rubina Koglgruber Shane J.
