Ramon Planas,Belén Ballesté,Marco Antonio Álvarez,M. Rivera,Silvia Montoliu,J.A. Galeras,Justiniano Santos,Susanna Coll,Rosa Maria Morillas,Ricard Solà +9 more
TL;DR: Once decompensated HCV-related cirrhosis was established, patients showed not only a very high frequency of readmissions, but also developed decompensations different from the initial one, which contribute to defining the natural course and prognosis of decompensation HCv-related Cirrhosis.
Journal ArticleDOI
Oral bile acids reduce bacterial overgrowth, bacterial translocation, and endotoxemia in cirrhotic rats☆
Vicente Lorenzo-Zúñiga,Ramon Bartolí,Ramon Planas,Alan F. Hofmann,Belén Viñado,Lee R. Hagey,Lee R. Hagey,José Ma Hernández,J. Mañé,Marco Antonio Álvarez,Vicente Ausina,Miquel A. Gassull +11 more
TL;DR: The administration of conjugated bile acids to ascitic cirrhotic rats increased bile acid secretion, eliminated intestinal bacterial overgrowth, decreased bacterial translocation, decreased endotoxemia, and increased survival.
Journal ArticleDOI
The effects of fish oil, olive oil, oleic acid and linoleic acid on colorectal neoplastic processes.
Xavier Llor,Elisenda Pons,A Roca,Marco Antonio Álvarez,Josep Mañé,Fernando Fernández-Bañares,Miquel A. Gassull +6 more
TL;DR: Fish oil and olive oil are capable of influencing crucial processes responsible for colorectal cancer development and COX-2 and Bcl-2 may be important mediators of some of these effects.
Journal ArticleDOI
Effect of olive oil on early and late events of colon carcinogenesis in rats: modulation of arachidonic acid metabolism and local prostaglandin E2 synthesis
Ramon Bartolí,Fernando Fernández-Bañares,E Navarro,E. Castellà,Josep Mañé,Marco Antonio Álvarez,C. Pastor,Eduard Cabré,Miquel A. Gassull +8 more
TL;DR: Dietary olive oil prevented the development of aberrant crypt foci and colon carcinomas in rats, suggesting that olive oil may have chemopreventive activity against colon carcinogenesis.
Journal ArticleDOI
Real-life chromoendoscopy for neoplasia detection and characterisation in long-standing IBD
Sabela Carballal,Sandra Maisterra,Antonio López-Serrano,Antonio Z. Gimeno-García,María Isabel Vera,José Carlos Marín-Garbriel,J Díaz-Tasende,Lucía Márquez,Marco Antonio Álvarez,Luis Hernández,Luísa Castro,Jordi Gordillo,Ignasi Puig,Pablo Vega,Marco Bustamante-Balén,Juan Acevedo,Beatriz Peñas,María López-Cerón,Elena Ricart,Miriam Cuatrecasas,Mireya Jimeno,Maria Pellise +21 more
TL;DR: In vivo, CE optical diagnosis is highly accurate for ruling out dysplasia, especially in expert hands, and can aid the endoscopist for in situ therapeutic decisions.
