Nowadays, we live in an age where technologies are part of our daily lives and directly influence the way we interpret and act in the world. The media is an example of technology, which makes it possible to transport information quickly and interactively. Among the existing media, one of the most used by the population is the television set. A examples of content that has been shown on television is the advertising of the campaign "AGRO WEALTH-INDUSTRY OF BRAZIL", which since 2016 have featured on Rede Globo advertisements about the Brazilian agribusiness and the contribution of this sector to the country's economy. The purpose of this work was to study what the advertising of the "AGRO" campaign is showing to Brazilian television viewers. To develop the research, we analyzed two campaign advertisements already shown on television ("Agricultural sector is the largest water consumer in Brazil" and "Agro on Globo showed the richness of the Brazilian countryside") through film analysis and decoupage technique. We also looked at how often current television advertisements are shown over a six-month period. Both advertisements analyzed presented quick cuts of scenes with content diversity and presented only the positive aspects of Brazilian agribusiness. On the frequency display, current advertisements were aired mainly on prime time television and on weekends that TV viewing audience is higher. The research has shown that although the campaign advertisements are considerably informative and can be used as an educational resource for environmental education, it is necessary that the reflections on advertising be constructed based on criticality and knowledge, to which the school can contribute. This is because the campaign reports, but also naturalizes the social and environmental impacts of agribusiness, since there is a marketing interest behind the information that mainly prioritizes profit sector. Thus, we conclude that the campaign advertisements displayed on Rede Globo television have an impact on society, and further studies on the theme may help to understand this influence.
Aims: To evaluate the effects of hyperlipidic diet on the mouse prostate and also investigate if physical exercise is able to restore such effects. Methodology: Adult male Swiss mice were fed with a balanced (ND) or hyperlipidic diet (45% saturated fat, HD) for 16 weeks. Half were submitted to a sedentary (NDS and HDS) or exercise routine (swimming- NDE and HDE) for 8 weeks. Then, the prostate was analyzed by immunoreactions (proliferating cell nuclear antigen- PCNA, androgen receptor- AR, and estrogen receptor-ERβ), western blotting (ERK 1/2), and caspase-3 activity. Results: We found that saturated fat uptake promoted 16% weight gain, increased fat-mass and hyperglycaemia, as well as reduced testosterone levels. In addition, HD atrophied prostate secretory epithelium and stimulated cell proliferation through higher expression of AR and activation of ERK signaling. Additionally, saturated fat reduced prostatic ERβ content. Physical exercise per se promoted an anabolic effect by increasing testosterone and stimulating cell proliferation in the prostate of sedentary animals. Finally, exercise was able to restore the proliferative signals caused by the hyperlipidic diet on prostate. Conclusion: We suggest that the combination of hyperlipidic diet and sedentary lifestyle could negatively affected some prostate stimulating pathways that could trigger proliferative diseases in mice and physical exercise may be an interesting strategy to reverse such effects.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
