AIM: To evaluate and present our experience with laparoscopic Roux en Y gastric bypass (RYGB) in a selected patient population. METHODS: A cohort of 130 patients with a body mass index (BMI) between 35 and 50 kg/m2 were evaluated in relation to postoperative morbidity,weight loss and resolution of co-morbidities for a period of 4 years following laparoscopic RYGB. RESULTS: Early morbidity was 10.0%,including 1 patient with peritonitis who was admitted to Intensive Care Unit (ICU) and 1 conversion to open RYGB early in the series. There was no early or late mortality. Maximum weight loss was achieved at 12 mo postoperatively,with mean BMI 30 kg/m2,mean percentage of excess weight loss (EWL%) 66.4% and mean percentage of initial weight loss (IWL%) 34.3% throughout the follow-up period. The majority of preexisting comorbidities were resolved after weight loss and no major metabolic disturbances or nutritional deficiencies were observed. CONCLUSION: Laparoscopic RYGB appears to be a safe and effective procedure for patients with BMI 35-50 kg/m2 with results that are comparable to previously published data mostly from the USA but from Europe as well.

AIM: To assess the value of gray scale (GS) and colour Doppler ultrasonography (CDU) in differentiating the progression of chronic viral hepatitis (CVH) and compensated liver cirrhosis (CIR). METHODS: Seventy-two patients and 32 normal individuals who were used as controls were studied. Forty-four patients suffered from CVH and 28 from CIR. All patients were underwent to liver biopsy. Multiple qualitative and quantitative variables were studied in liver, portal vein (PV), hepatic artery (HA) and spleen with GS and CDU. On the basis of the obtained CDU data, several known indexes were calculated. In addition, alternative indices [PV diameter (D)/time average mean velocity (VTAM), HA/PV VTAM ratio] were calculated and studied. RESULTS: ROC analysis showed that PV congestion index, PV D/VTAM and HA/PV VTAM indices had the best sensitivity and specificity in discriminating CVH from CIR. Stepwise discriminant analysis showed that 88.9% of the originally grouped cases could be correctly classified by the three qualitative and four quantitative variables selected as statistically significant predictors. Among the CVH patients who underwent to biopsy, statistically significant changes were found in those at fibrosis stage 5 compared to fibrosis stages 1-4. CONCLUSION: Simple GS and CDU parameters discri-minate CVH from CIR. The alternative Doppler indexes can accurately differentiate chronic virus hepatitis from cirrhosis. These indexes can be used in monitoring chronic virus hepatitis and avoiding unnecessary biopsies.

Light soaking characterization on complete SnO2:F/TiO2/In(OH)xSy/Pb(OH)xSy/PEDOT:PSS/Au, eta solar cell structure as well as on devices which do not include one or both TiO2 and/or PEDOT:PSS layers has been conducted. Additionally, studies of SnO2:F/In(OH)xSy/Pb(OH)xSy/PEDOT:PSS/Au solar cell have been performed. The power conversion efficiency and the short circuit current density have been found to increase with light soaking duration by a factor of about 1.6 - 2.7 and 2.1 - 3, respectively. The increase in these two parameters has been attributed to the filling up of trap states and/or charge-discharge of deep levels found in In(OH)xSy. These effects take place at almost fill factor and open circuit voltage being unaffected by the light soaking effects.

欧盟国家的主要能源是化石燃料,将近2/3依靠进口。预计未来化石燃料在欧洲能源平衡方面的作用还将增强,进口能源将占能源消耗总量的70%以上。另一方面,发展可再生能源资源是欧盟能源政策的一个中心目标。文章阐述了欧盟10个新成员国可再生能源资源的利用状况、以及相关的政策和前景。接纳欧盟可再生能源方面的政策对促进欧盟新成员国之间的合作至关重要,并且势在必行。各国间技术和经验的交流可以促进成员国为了达到2010年可再生能源占欧盟总能源消费的12%这一目标而实施计划。

各种灵活的京都机制已经作为以市场为基础的解决气候变化的方法发展起来了。更具体的说,清洁发展机制(CDM)是指一个工业化国家通过在发展中国家实施减排项目(特别是可再生能源项目)来实现其部分减排义务的一种灵活机制。目前发展中国家没有承担减少温室气体排放方面的义务。介绍了京都议定书的清洁发展机制促进可再生能源(RES)投资的能力,并且分析了在CDM机制下小型项目的发展潜力。
