This work consists of a semiotic analysis of the animation motion picture The Lion King (1994), by the Walt Disney Animation Studios, describing its intertextual relation with Hamlet, by Shakespeare, considering Disney’s individuality, its style. In order to study style in texts, we use discursive semiotics theory, highlighting Discini’s work (2013) and the concept of discursive settings. Hence, a deep discussion about The Lion King’s style, compared to the Shakespeare’s play, is established. The movie, once a syncretic text, requires advanced studies on Expression Plane, its plastic, musical and verbal/phonic aspects. We find these studies in the work of José Luiz Fiorin (2009), Lúcia Teixeira (2009), Ana Claúdia de Oliveira (2009), Jean-Marie Floch (2009) and Antônio Vicente Pietroforte (2008). We note how a syncretic text makes the discursive settings more complex by assembling plastic and sonorous materials in semissimbolic relation. Once defined The Lion King’s style, we analyze the way it justifies the intense popularity of this kind of animation features. Finally, it is important to understand how Disney uses in its style not only discursive settings, but also passional settings, revealing its own way to stir emotions on the spectator

Introdução:.O cultivo de plantas medicinais é uma prática essencial para a conservação das espécies e para garantir a oferta de matéria-prima com padrão de qualidade constante. Para que a terapia com plantas medicinais tenha eficácia e segurança, é imprescindível ao longo do cultivo, a execução de práticas fitotécnicas adequadas a cada espécie vegetal, visto que o desenvolvimento desta está sob a influencia das variações climáticas, dos cuidados com a irrigação, adubação, etc. Objetivo: Verificar os efeitos de diferentes doses de vermicomposto na produção de matéria seca e óleo essencial de Foeniculum vulgare Mill., cultivado em vasos em condições de estufa agrícola. Material e métodos: Sementes de F. vulgare foram colhidas no Horto de Plantas Medicinais e Tóxicas da FCF-UNESP e semeadas em vasos de 300 mL. Após 40 dias da semeadura as mudas foram transplantadas para vasos de 4L contendo solo tratado com vermicomposto nas doses de 0, 15, 30, 45 e 60 t ha-1. Ao final de 90 dias de cultivo as partes aéreas (folhas e caules) foram colhidas, secadas e analisadas quanto ao teor de óleo essencial. A identificação do anetol no óleo essencial foi realizada por CCD. Resultados: Os tratamentos durante o período de cultivo analisado influenciaram a produção de biomassa das plantas e também a produção do óleo essencial, porém sem uma correspondência diretamente proporcional. As plantas tenderam a produzir mais biomassa do que óleos essenciais em relação ao tratamento testemunha. Conclusão: Houve influência das doses de vermicomposto no cultivo de funcho (durante 90 dias, em vasos, em casa de vegetação), porém não correlacionada à produção de óleo essencial das folhas.

The aim of this study was to evaluate the antimicrobial and cytotoxic effect of essential oil (EO) of lemon grass (Cymbopogon citratus). From the agar diffusion method, different concentrations of EO (0.135%, 0.2% and 1%), and control solutions (chlorhexidine (Chx), distilled water (Ad) and cereal alcohol (Ac)) were applied on cultures of Candida albicans (C.a), Streptococcus mutans (S.m), Streptococcus sobrinus (S.sob) and Lactobacillus acidophilus (L.a). For C.a, S.m and S.sob, the largest inhibition zones in descending order were: Chx, Ac and EO 1%, while the latter two were statistically similar (Mann-Whitney, p> 0.05). For L.a, the largest inhibition halo was observed for the Chx, followed by EO at 1%, 0.2%, 0.135% and Ac. For evaluation of cytotoxicity, the following groups were set: G1: 0,1% EO; G2: pure EO; G3 (positive control): H2 O2 ; G4: cereal alcohol; and G5 (negative control): culture medium – DMEM. The solutions were applied on the cultured MDPC-23 cells, which were plated (30,000 cells/cm2 ) in wells of 24 well-dishes. Cell metabolism was evaluated by MTT assay. Considering G5 (negative control) as 100% of cell metabolism, it was observed for G1, G2, G3 and G4 a percentage reduction in cell metabolism of 29.6%, 82%, 81.2% and 33.4%, respectively. It was concluded that the low concentration of 0,1% OE (C. citratus) was able to inhibit the growth of the strains tested as well as caused mild cytotoxicity to the cultured MDPC-23 cells.

Objective: To compare the efficacy of the mouthwashes 0.12% chlorhexidine, Listerine, and 0.5% and 2% Melaleuca Alternifolia oil against the salivary levels of Streptococcus mutans and total microorganisms. Methods: This study was double-blind controlled and paired clinical assay. Twenty-six volunteers aged 21 to 35 years old were enrolled. At baseline, 1 mL of unstimulated saliva was collected from each subject, 1 and 15 min after mouthrinsing with the following solutions: sterile distilled water, 0.12% chlorhexidine digluconate, Listerine (©Johnson & Johnson do Brasil), 0.5% and 2% concentrations of Melaleuca Alternifolia (Sigma-Aldrich). The volunteers used all the evaluated mouthrinses with a 15-day interval between the solutions. Immediately after rinsing, saliva was collected and serial dilutions were performed, followed by plating in blood agar culture medium for growth of total microorganisms and SB-20 (Sucrose-Bacitracin agar) for growth of S. mutans, and incubation at 37 °C for 48 h in microaerophilia. After incubation, the number of colonies was counted and expressed as colony forming units (UFC/mL). Results: Chlorhexidine showed antimicrobial action by reducing total microorganisms and S. mutans, while the action of 0.5% Melaleuca Alternifolia was similar to that of distilled water. Listerine and 2% Melaleuca Alternifolia oil reduced total microbial counts by 11% and 9% respectively, and S. mutans by 20% and 11%. Conclusion: A single rinse with 0.12% chlorhexidine is effective in reducing the levels of total microorganisms and S. mutans present in saliva. Under the same testing conditions, Listerine and 0.5% and 2% Melaleuca Alternifolia oil presented lower efficacy than chlorhexidine.
