RESUMO
The side stream cigarette smoke (SSCS) is a contributing factor in the pathogenesis of cigarette smoking-induced toxicity. Hemoglobin (Hb), myoglobin (Mb), neuroglobin (Ngb), and cytoglobin (Cygb) are globins with different distributions and functions in the tissues and have similar actions by providing O2 (oxygen) for respiratory chain, detoxification of ROS and nitric oxide (NO), and protect tissues against irreversible lesions. We aimed to investigate the effects of SSCS exposure on gene and protein expression of Ngb, Cygb, and Mb in different tissue. The Ngb and Cygb gene and protein expression in the cerebral cortex increased after 1 week of rat exposure to SSCS. In hippocampus, the Ngb gene and protein expression increased after 1 week or more of exposure and no change was observed in Cygb gene and protein expression. In myocardium, Mb and Cygb gene expression increased at 1 and 4 weeks of exposure, while protein expression of both increased at 1, 2, 3, and 4 weeks. In lung, observed an increase in Cygb gene and protein expression after 2, 3, and 4 weeks of exposure. The findings suggest that SSCS modulates Ngb, Cygb, and Mb in central and peripheral tissue © 2016 Wiley Periodicals, Inc. Environ Toxicol 32: 1252-1261, 2017.

OBJECTIVE: To assess psychiatric symptoms, substance use, quality of life and eating behavior of patients undergoing bariatric surgery before and after the procedure. METHODS: We conducted a prospective longitudinal study of 32 women undergoing bariatric surgery. To obtain data, the patients answered specific, self-administered questionnaires. RESULTS: We observed a reduction in depressive and anxious symptoms and also in bulimic behavior, as well as an improved quality of life in the physical, psychological and environmental domains. There was also a decrease in use of antidepressants and appetite suppressants, but the surgery was not a cessation factor in smoking and / or alcoholism. CONCLUSION: a decrease in psychiatric symptoms was observed after bariatric surgery, as well as the reduction in the use of psychoactive substances. In addition, there was an improvement in quality of life after surgical treatment of obesity.

OBJETIVO: avaliar a sintomatologia psiquiátrica, o uso de substâncias, a qualidade de vida e o comportamento alimentar de pacientes submetidos a cirurgia bariátrica antes e após o procedimento. MÉTODOS: estudo longitudinal prospectivo com 32 mulheres submetidas à cirurgia báriatrica. Para a obtenção de dados, as pacientes responderam a questionários específicos, autoaplicados. RESULTADOS: foi identificada uma redução na sintomatologia depressiva e ansiosa e também no comportamento bulímico, bem como uma melhora na qualidade de vida nos domínios físico, psíquico e ambiental. Houve diminuição do uso de antidepressivos e de moderadores de apetite, porém a cirurgia não foi um fator determinante na cessação do tabagismo e/ou etilismo. . CONCLUSÃO: foi observada uma diminuição da sintomatologia psiquiátrica após a cirurgia bariátrica, bem como redução do uso de substâncias psicoativas. Além disso, houve melhora na qualidade de vida após o tratamento cirúrgico da obesidade. .
