Articulação psicossociológica sobre a cidade ideal: como compreender umvulcão atiçado e adormecido pela Copa do Mundo de futebol / Psychosociological articulation about the Ideal City: how can we understand a volcano fanned and inactivated by the FIFA World Cup

A cidade desejada pelos habitantes tem cada vez mais se tornado tema de debates em espaços diversos, dos formais aos cotidianos. No Brasil, este fenômeno se ampliou, especialmente a partir de 2013, quando as Jornadas de Junho deram ênfase aos diversos problemas pelos quais têm passado os moradores urbanos, trazendo a pauta ao centro das atenções e conquistando a adesão de milhares de pessoas a passeatas de rua, como há muitosanos não se via no país. Teria todo este fervor esfriado em 2014, sob efeito das emoções pela realização da Copa do Mundo de Futebol ou a herança dos megaeventos tornará a esquentar ocenário urbano nacional? É essencial que os psicólogos sociais se envolvam na compreensão deste processo, contribuindo ativamente com o debate e com as ações a serem tomadas paramelhorar a qualidade de vida e o convívio dentro das cidades. Uma abordagem que tem se mostrado frutífera neste intento é a articulação psicossociológica, proposta por Willem Doise e colaboradores, que defendem a superação da clivagem entre análises centradas no indivíduo ou na sociedade e a direção do olhar dos pesquisadores para as transformações societais por que passamos, atuando a partir da necessidade de mudanças sociais.

The city desired by the inhabitants has increasingly become a topic of discussion in many places, from the formal to the ordinaries. In Brazil, this phenomenon has expanded especially after 2013, when the event known as “Jornadas de Junho” (June Journeys) emphasized many problems that the urban residents have been facing, bringing the topic to the limelight andgaining membership of thousands of people to street protests, like there wasn't been seen in many years in the country. Would all this fervor cooled in 2014, under narcotic effect of emotionsby hosting the FIFA World Cup or the inheritance of mega-events will inflame the national urban setting? It is essential that social psychologists implicate themselves in understanding this process, actively contributing to the debate and the actions to be taken to improve the quality of life and the social relations in cities. One approach that has been fruitful in this endeavor is thepsychosociological articulation proposal by Willem Doise and colleagues, who defends the overcoming of the cleavage between analyzes focused on the individual or society and the direction of the researchers view to the societal transformations, acting from the need for social changes.

Silymarin reduces profibrogenic cytokines and reverses hepatic fibrosis in chronic murine schistosomiasis.

In chronic schistosomiasis, hepatic fibrosis is linked to the portal hypertension that causes morbidity in Schistosoma mansoni infection. Silymarin (SIL) is a hepatoprotective and antioxidant medicament largely prescribed against liver diseases that has previously been shown to prevent fibrosis during acute murine schistosomiasis. Here we employed silymarin to try to reverse established hepatic fibrosis in chronic schistosomiasis. Silymarin or vehicle was administered to BALB/c mice every 48 h, starting on the 40th (80 days of treatment), 70th (50 days), or 110th (10 days) day postinfection (dpi). All mice were sacrificed and analyzed at 120 dpi. Treatment with silymarin reduced liver weight and granuloma sizes, reduced the increase in alanine aminotransferase and aspartate aminotransferase levels, and reduced the established hepatic fibrosis (assessed by hydroxyproline contents and picrosirius staining). Treatment with silymarin also reduced the levels of interleukin-13 (IL-13) in serum and increased the gamma interferon (IFN-γ)/IL-13 ratio. There was a linear correlation between IL-13 levels in serum and hydroxyproline hepatic content in both infected untreated and SIL-treated mice, with decreased IL-13 levels corresponding to decreased hydroxyproline hepatic contents. Treatment with either SIL or N-acetylcysteine reduced both proliferation of fibroblast cell lines and basal/IL-13-induced production of collagen I, indicating that besides inhibiting IL-13 production during infection, SIL antioxidant properties most likely contribute to inhibition of collagen production downstream of IL-13. These results show that silymarin interferes with fibrogenic cytokines, reduces established fibrosis, and inhibits downstream effects of IL-13 on fibrogenesis, indicating the drug as a safe and cheap treatment to liver fibrotic disease in schistosomiasis.

Silymarin treatment reduces granuloma and hepatic fibrosis in experimental schistosomiasis.

The schistosomiasis is a parasitic infection with relevant social impact and an important health problem in many countries around world. The pathology of this infection is characterized by a granulomatous reaction around parasite eggs and by hepatic fibrosis. Silymarin, a complex compound isolated from Silybum marianum (L.) Gaertner, have been described as hepatoprotective, antioxidant, antifibrotic, immunomodulator, and anti-neoplastic agent. Some of these capacities could potentially protect against pathology in schistosomiasis. Herein, we evaluated the effects of silymarin on parasite burden, granuloma sizes, and liver fibrosis, which are associated with severity and morbidity of this disease. BALB/c mice treated intraperitoneally with 10, 20, or 25 doses of silymarin (10 mg kg(-1)) suspended in carboxymethylcellulose were analyzed at 55 days post-infection. Silymarin (1) did not affect parasite oviposition capacity; (2) reduced granulomatous peri-ovular reaction in the liver, and (3) decreased hepatic fibrosis in this infection. Taken together, these data suggest that treatment with silymarin at acute phase of schistosomiasis may result in a mild course of murine schistosomiasis and can be a promising complementary treatment reverting sequelae of this infection.
