Estudo de diferentes alturas de repicagem na produção de biomassa de porta-enxertos cĂtricos em sistema hidropĂŽnico.
A citricultura brasileira Ă© a mais competitiva do mundo, com produção de 19.112.251 toneladas em 2010/11, sendo o Estado de SĂŁo Paulo o principal produtor, com safra de laranja (2010/11) em torno de 290 milhĂ”es de caixas (AGRIANUAL, 2012). VĂĄrios sĂŁo os fatores levados em consideração na ocasiĂŁo da implantação de um pomar cĂtrico, porĂ©m, Ă© consenso que a escolha de mudas de qualidade atestada Ă© fator preponderante no sucesso da atividade. Pompeu JĂșnior (2005) enfatiza que os porta-enxertos afetam diversas caracterĂsticas das variedades copas, tais como: vigor, produção e sua precocidade, tolerĂąncia da planta Ă s adversidades climĂĄticas, alĂ©m de caracterĂstica que conferem maior qualidade ao fruto
Polypropylene meshes coated with chitosan/polyethylene glycol for the reconstruction of the abdominal wall: an experimental study in rats
The aim of this study was to characterize the tissue reactions triggered by the polypropylene mesh coated with chitosan and polyethylene glycol film, and if it's able to prevent the formation of peritoneal adhesions. Defects in the abdominal wall of rats were induced and polypropylene meshes coated with chitosan/polyethylene glycol (CPEG group, n= 12) and uncoated (PP control group, n= 12) were implanted. On the fourth and forty-fifth postoperative day the formation of adhesion and the tissue reaction to the biomaterial was evaluated through histological and histochemical analysis. The area (P= 0.01) and severity (P= 0.002) of the adhesion was significatively less in the CPEG group. On the fourth day the foreign body reaction was less intense in CPEG group (P= 0.018) and the production of collagen fibers was more intense in this group (P= 0.041). The tissue reactions caused by the biomaterials were similar on the 45th day, with the exception of the high organization of collagen fibers in the CPEG group. The CPEG meshes did not fully prevent the formation of adhesions, but minimized the severity of the process. The foreign body reaction promoted by polypropylene meshes coated with CPEG is less intense than that triggered by uncoated polypropylene meshes71411981206CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTĂFICO E TECNOLĂGICO - CNPQCOORDENAĂĂO DE APERFEIĂOAMENTO DE PESSOAL DE NĂVEL SUPERIOR - CAPESFUNDAĂĂO DE AMPARO Ă PESQUISA DO ESTADO DE SĂO PAULO - FAPESPsem informaçãosem informaçãosem informaçã
