| 1 | High-definition colonoscopy with i-Scan:Better diagnosis for small polyps and flat adenomas显示文摘AIM:To investigate if high-definition (HD) colonoscope with i-Scan gave a higher detection rate of mucosal lesions vs standard white-light instruments. METHODS:Data were collected from the computerized database of the endoscopy unit of our tertiary referral center. We retrospectively analyzed 1101 consecutive colonoscopies that were performed over 1 year with standard white-light (n = 849) or HD+ with i-Scan (n = 252) instruments by four endoscopists, in an outpatient setting. Colonoscopy records included patients' main details and family history for colorectal cancer, indication for colonoscopy (screening, diagnostic or surveillance), type of instrument used (standard white-light or HD+ plus i-Scan), name of endoscopist and bowel preparation. Records for each procedure included whether the cecum was reached or not and the reason for failure, complications during or immediately after the procedure, and number, size, location and characteristics of the lesions. Polyps or protrudinglesions were defined as sessile or pedunculated, and nonprotruding lesions were defined according to Paris classification. For each lesion, histological diagnosis was recorded. RESULTS:Eight hundred and forty-nine colonoscopies were carried with the standard white-light video colonoscope and 252 with the HD+ plus i-Scan video colonoscope. The four endoscopists did 264, 300, 276 and 261 procedures, respectively; 21.6%, 24.0%, 21.7% and 24.1% of them with the HD+ plus i-Scan technique. There were no significant differences between the four endoscopists in either the number of procedures done or the proportions of each imaging technique used. Both techniques detected one or more mucosal lesions in 522/1101 procedures (47.4%). The overall number of lesions recognized was 1266; 645 in the right colon and 621 in the left. A significantly higher number of colonoscopies recognized lesions in the HD+ plus i-Scan mode (171/252 = 67.9%) than with the standard white-light technique (408/849 = 48.1%) (P < 0.0001). HD+ with i-Scan colonoscopies identified more lesions than standard white-light imaging (459/252 and 807/849, P < 0.0001), in the right or left colon (mean ± SD, 1.62 ± 1.36 vs 1.33 ± 0.73, P < 0.003 and 1.55 ± 0.98 vs 1.17 ± 0.93, P = 0.033), more lesions < 10 mm (P < 0.0001) or nonprotruding (P < 0.022), and flat polyps (P = 0.04). The cumulative mean number of lesions per procedure detected by the four endoscopists was significantly higher with HD+ with i-Scan than with standard white-light imaging (1.82 ± 2.89vs 0.95 ± 1.35,P < 0.0001). CONCLUSION:HD imaging with i-Scan during the withdrawal phase of colonoscopy significantly increased the detection of colonic mucosal lesions, particularly small and nonprotruding polyps. | Pier Alberto Testoni Chiara Notaristefano Cristian Vailati Milena Di Leo Edi Viale | 2012 | World Journal of Gastroenterology2012，18，37： | 12 |
| 2 | Ventilator associated pneumonia following liver transplantation:Etiology,risk factors and outcome显示文摘AIM: To determine the incidence, etiology, risk factors and outcome of ventilator-associated pneumonia(VAP) in patients undergoing orthotopic liver transplantation(OLT).METHODS: This retrospective study considered 242 patients undergoing deceased donor OLT. VAP was diagnosed according to clinical and microbiological criteria. RESULTS: VAP occurred in 18(7.4%) patients, with an incidence of 10 per 1000 d of mechanical ventilation(MV). Isolated bacterial etiologic agents were mainly Enterobacteriaceae(79%). Univariate logistic analysis showed that model for end-stage liver disease(MELD) score, pre-operative hospitalization, treatment with terlipressin, Child-Turcotte-Pugh score, days of MV and red cell transfusion were risk factors for VAP. Multivariateanalysis, considering significant risk factors in univariate analysis, demonstrated that pneumonia was strongly associated with terlipressin usage, pre-operative hospitalization, days of MV and red cell transfusion. Mortality rate was 22% in the VAP group vs 4% in the group without VAP. CONCLUSION: Our data suggest that VAP is an important cause of nosocomial infection during postoperative period in OLT patients. MELD score was a significant risk factor in univariate analysis. Multiple transfusions, treatment with terlipressin, preoperative hospitalization rather than called to the hospital while at home and days of MV constitute important risk factors for VAP development. | Antonio Siniscalchi Lucia Aurini Beatrice Benini Lorenzo Gamberini Stefano Nava Pierluigi Viale Stefano Faenza | 2016 | World Journal of Transplantation2016，6，2： | 9 |
| 3 | Zinc oxide nano-enabled microfluidic reactor for water purification and its applicability to volatile organic compounds显示文摘This paper reports fast and efficient chemical decontamination of water within a tree-branched centimeter-scale microfluidic reactor.The microreactor integrates Zinc oxide nanowires(ZnO NWs)in situ grown acting as an efficient photocatalytic nanomaterial layer.Direct growth of ZnO NWs within the microfluidic chamber brings this photocatalytic medium at the very close vicinity of the water flow path,hence minimizing the required interaction time to produce efficient purification performance.We demonstrate a degradation efficiency of 95%in o5 s of residence time in one-pass only.According to our estimates,it becomes attainable using microfluidic reactors to produce decontamination of merely 1 l of water per day,typical of the human daily drinking water needs.To conduct our experiments,we have chosen a laboratory-scale case study as a seed for addressing the health concern of water contamination by volatile organic compounds(VOCs),which remain difficult to remove using alternative decontamination techniques,especially those involving water evaporation.The contaminated water sample contains mixture of five pollutants:Benzene;Toluene;Ethylbenzene;m–p Xylenes;and o-Xylene(BTEX)diluted in water at 10 p.p.m.concentration of each.Degradation was analytically monitored in a selective manner until it falls below 1 p.p.m.for each of the five pollutants,corresponding to the maximum contaminant level(MCL)established by the US Environmental Protection Agency(EPA).We also report on a preliminary study,investigating the nature of the chemical by-products after the photocatalytic VOCs degradation process. | Imadeddine Azzouz Yamina Ghozlane Habba Martine Capochichi-Gnambodoe Frédéric Marty Jérôme Vial Yamin Leprince-Wang Tarik Bourouina | 2018 | Microsystems & Nanoengineering2018，4，1： | 4 |

| 5 | Mitochondria-associated endoplasmic reticulum membranes allow adaptation of mitochondrial metabolism to glucose availability in the liver显示文摘Mitochondria-associated endoplasmic reticulum membranes(MAM)play a key role in mitochondrial dynamics and function and in hepatic insulin action.Whereas mitochondria are important regulators of energy metabolism,the nutritional regulation of MAM in the liver and its role in the adaptation of mitochondria physiology to nutrient availability are unknown.In this study,we found that the fasted to postprandial transition reduced the number of endoplasmic reticulum-mitochondria contact points in mouse liver.Screening of potential hormonal/metabolic signals revealed glucose as the main nutritional regulator of hepatic MAM integrity both in vitro and in vivo.Glucose reduced organelle interactions through the pentose phosphate-protein phosphatase 2A(PP-PP2A)pathway,induced mitochondria fission,and impaired respiration.Blocking MAM reduction counteracted glucose-induced mitochondrial alterations.Furthermore,disruption of MAM integrity mimicked effects of glucose on mitochondria dynamics and function.This glucose-sensing system is deficient in the liver of insulin-resistant ob/ob and cyclophilin D-KO mice,both characterized by chronic disruption of MAM integrity,mitochondrial fission,and altered mitochondrial respiration.These data indicate that MAM contribute to the hepatic glucose-sensing system,allowing regulation of mitochondria dynamics and function during nutritional transition.Chronic disruption of MAM may participate in hepatic mitochondrial dysfunction associated with insulin resistance. | Pierre Theurey Emily Tubbs Guillaume Vial Julien Jacquemetton Nadia Bendridi Marie-Agnes Chauvin Muhammad Rizwan Alam Muriel Le Romancer Hubert Vidal Jennifer Rieusset | 2016 | Journal of Molecular Cell Biology2016，8，2： | 2 |

| 8 | No Evidence of Effect on Male Mice Germ Cells After Acute Treatment With Thiram显示文摘Thiram is a dithiocarbamate compound widely used for industrial processes and agriculture. Animal studies reveal that this compound may afftct the male reproductive system. Aim of this study was to test, using sensitive testicular parameters, whether thiram directly affects germinal cells. For this purpose, B6C3F1 mice were intraperitoneally injected with thiram in oil (single dose:75 mg/kg; repeated five daily doses: 25 mg/kg).Although both treatments were toxic, none of the parameters examined, i.e., testis weighi, spermatid head number,specific enzyme levels at different times after treatment (14, 28, 35, 56 days) showed significant variations from the controls, On the contrary, in the positive controls (treated with chlorambucil), a marked reduction of sperm head number as well as a deerease of lactate dehydrogenasex and sorbitol dehydrogenase activity letels were evidenced at day 28, with a tendency to recover at day 35. Under these conditions thiram did not cause cytotoxicity on differentiating spermatogonia and on late spermatocyte stages of mice | M.E.TRAINA P. ADE AND E.
