| 1 | Alcohol metabolites and lipopolysaccharide: Roles in the development and/or progression of alcoholic liver disease显示文摘The onset of alcoholic liver disease (ALD) is initiated by different cell types in the liver and a number of different factors including: products derived from ethanol-induced inflammation, ethanol metabolites, and the indirect reactions from those metabolites. Ethanol oxidation results in the production of metabolites that have been shown to bind and form protein adducts, and to increase inflammatory, fibrotic and cirrhotic responses. Lipopolysaccharide (LPS) has many deleterious effects and plays a significant role in a number of disease processes by increasing inflammatory cytokine release. In ALD, LPS is thought to be derived from a breakdown in the intestinal wall enabling LPS from resident gut bacterial cell walls to leak into the blood stream. The ability of adducts and LPS to independently stimulate the various cells of the liver provides for a two-hit mechanism by which various biological responses are induced and result in liver injury. Therefore, the purpose of this article is to evaluate the effects of a two-hit combination of ethanol metabolites and LPS on the cells of the liver to increase inflamma-tion and fi brosis, and play a role in the development and/or progression of ALD. | Courtney S Schaffert Michael J Duryee Carlos D Hunter Bartlett C Hamilton 3rd Amy L DeVeney Mary M Huerter Lynell W Klassen Geoffrey M Thiele | 2009 | World Journal of Gastroenterology2009,15,10: | 20 |
| 2 | Synthesis of advanced ceramics by hydrothermal crystallization and modified related methods显示文摘The present article aims to give a brief overview about the advantages of the hydrothermal crystallization method for the synthesis of advanced ceramics.Emphasis is given,not only on the conventional hydrothermal crystallization,but also on some of its variants;such as ultrasound-assisted,electrochemical-assisted,microwave-assisted and surfactant-assisted hydrothermal methods which open up new opportunities for the synthesis of ceramic materials with novel properties demanded for advanced applications.In the current work the synthesis of barium titanate(BaTiO3),lithium metasilicate(Li2SiO3)and sodium-potassium niobate(Na,K)NbO3 powders are reported as cases of study. | JoséORTIZ-LANDEROS Carlos GÓMEZ-YÁÑEZ Rigoberto LÓPEZ-JUÁREZ Iván DÁVALOS-VELASCO Heriberto PFEIFFER | 2012 | Journal of Advanced Ceramics2012,1,3: | 6 |
| 3 | High prevalence of viable Mycobacterium avium subspecies paratuberculosis in Crohn's disease显示文摘AIM:To examine the detection rate of viable Mycobacterium avium subspecies paratuberculosis(MAP) in patients with inflammatory bowel disease [Crohn's disease(CD) and ulcerative colitis(UC)].METHODS:Thirty patients with CD(15 with at least one NOD2/CARD15 mutation),29 with UC,and 10 with no inflammatory bowel disease(IBD).were tested for MAP by polymerase chain reaction(specific IS900 fragment) and blood culture.RESULTS:MAP DNA was detected in all original blood samples and 8-wk blood cultures(CD,UC and non-IBD).Positive MAP DNA status was confirmed by dot blot assays.All 69 cultures were negative by acid-fast Ziehl-Neelsen staining.Viable MAP,in spheroplast form,was isolated from the 18-mo blood cultures of all 30 CD patients,one UC patient,and none of the non-IBD controls.No association was found between positive MAP cultures and use of immunosuppressive drugs or CDassociated single nucleotide polymorphisms.CONCLUSION:MAP is widely present in our area and MAP DNA can be recovered from the blood of CD,UC and non-IBD patients.However,MAP spheroplasts were only found in CD patients. | Juan L Mendoza Amparo San-Pedro Esther Culebras Raquel Cíes Carlos Taxonera Raquel Lana Elena Urcelay Fernando de la Torre Juan J Picazo Manuel Díaz-Rubio | 2010 | World Journal of Gastroenterology2010,16,36: | 5 |
| 4 | Need for infliximab dose intensification in Crohn's disease and ulcerative colitis显示文摘AIM: To compare the need for infliximab dose intensification in two cohorts of patients with Crohn's disease(CD) or ulcerative colitis(UC).METHODS: Single centre, uncontrolled, observational study. Consecutive patients with CD and UC who responded to infliximab induction doses were included. Data collected in a prospectively maintained database were retrospectively analysed. Differences in the rates of dose intensification per patient-month and the intensification-free survival time were compared. We also evaluated the interval between the first infliximab induction dose and the first infliximab escalated dose. The weight-adjusted infliximab administration costs were also calculated.RESULTS: Fifty nine patients with CD and 38 patients with UC were enrolled. The rate of intensification per patient-month was 3.9% for UC and 1.4% for CD(P = 0.005). The median time from baseline to intensification was significantly shorter in UC compared to CD [6.6 mo(IQR: 4.2-9.5 mo) vs 10.7 mo(IQR: 8.9-11.7 mo), P = 0.005]. In the survival analysis, the cumulative probability of avoiding infliximab dose intensification was significantly higher in CD(P = 0.002). In the multivariate analysis, disease(UC vs CD) was the only factor significantly associated with dose intensification. The infiximab administration costs during the first year were significantly higher for UC compared to CD(mean ± SD 234.9 ± 53.3 Euros/kg vs 212.3 ± 15.1 Euros/kg, P = 0.03).CONCLUSION: The rate of infliximab dose intensification per patient-month is significantly higher in UC patients. The infliximab administration costs are also significantly higher in patients with UC. | Carlos Taxonera David Olivares Juan L Mendoza Manuel Díaz-Rubio Enrique Rey | 2014 | World Journal of Gastroenterology2014,20,27: | 2 |
| 5 | Lymphoepithelial cysts and cystic lymphangiomas: Underrecognized benign cystic lesions of the pancreas显示文摘AIM: To identify their diagnostic and prognostic clinical characteristics in a large series.METHODS: Retrospective review of clinicopathologic and imaging characteristics of patients diagnosed with lymphoepithelial cysts and cystic lymphangiomas of the pancreas at Massachusetts General Hospital.RESULTS: Twelve patients were identified between 1/1/1997 and 8/1/2007. Their median age was 55.5 years(range 19-78 years), and 6 were females. The le-sion was incidentally discovered in half of the patients.Contrast enhanced computed tomography demonstrat-ed that the cysts had thin walls, without calcifications, pancreatic duct dilation or pancreatic parenchyma inva-sion. Endoscopic ultrasound with fine needle aspiration(EUS/FNA) confirmed the diagnosis of a lymphoepithe-lial cyst in 3 patients, one of whom was spared an op-eration and continues to do well after 6 years. Eleven patients had a resection: 3 pancreaticoduodenecto-mies, 7 distal pancreatectomies, and 1 enucleation. The median size of the cysts was 3 cm(range 2-20 cm). At a median follow-up of 57 mo no recurrences or other pancreas-related conditions occurred.CONCLUSION: Lymphoepithelial cysts and cystic lymphangiomas of the pancreas can be diagnosed with a combination of contrast-enhanced computed tomog-raphy scans and EUS/FNA. If the lesion is asymptom-atic, an operation might be avoided. | Ioannis T Konstantinidis Avinash Kambadakone Onofrio A Catalano Dushyant V Sahani Vikram Deshpe David G Forcione Jennifer A Wargo Carlos Fernandez-del Castillo Keith D Lillemoe Andrew L Warshaw Cristina R Ferrone | 2014 | World Journal of Gastrointestinal Surgery2014,6,7: | 2 |
| 6 | 25 Gbps low-voltage hetero-structured silicongermanium waveguide pin photodetectors for monolithic on-chip nanophotonic architectures显示文摘Near-infrared germanium(Ge) photodetectors monolithically integrated on top of silicon-on-insulator substrates are universally regarded as key enablers towards chip-scale nanophotonics, with applications ranging from sensing and health monitoring to object recognition and optical communications. In this work, we report on the highdata-rate performance pin waveguide photodetectors made of a lateral hetero-structured silicon-Ge-silicon(Si-Ge-Si) junction operating under low reverse bias at 1.55 μm. The pin photodetector integration scheme considerably eases device manufacturing and is fully compatible with complementary metal-oxide-semiconductor technology. In particular, the hetero-structured Si-Ge-Si photodetectors show efficiency-bandwidth products of^9 GHz at-1 V and ~30 GHz at-3 V, with a leakage dark current as low as ~150 nA, allowing superior signal detection of high-speed data traffic. A bit-error rate of 10-9 is achieved for conventional 10 Gbps, 20 Gbps, and25 Gbps data rates, yielding optical power sensitivities of-13.85 dBm,-12.70 dBm, and-11.25 dBm, respectively. This demonstration opens up new horizons towards cost-effective Ge pin waveguide photodetectors that combine fast device operation at low voltages with standard semiconductor fabrication processes, as desired for reliable on-chip architectures in next-generation nanophotonics integrated circuits. | DANIEL BENEDIKOVIC LéOPOLD VIROT GUY AUBIN FARAH AMAR BERTRAND SZELAG BAYRAM KARAKUS JEAN-MICHEL HARTMANN CARLOS ALONSO-RAMOS XAVIER LE ROUX PAUL CROZAT ERIC CASSAN DELPHINE MARRIS-MORINI CHARLES BAUDOT FRéDéRIC BOEUF JEAN-MARC FéDéLI CHRISTOPHE KOPP LAURENT VIVIEN | 2019 | Photonics Research2019,7,4: | 2 |
