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.

Aim: To report a possible case of tremor fluoxetine-induced treated as Parkinson’s disease in an elderly female patient noncompliant with the pharmacotherapy, with uncontrolled hypertension and using fluoxetine to treat depression. Presentation of Case: Patient complained of sleepiness in the morning, agitation, anxiety, insomnia and mental confusion. Her greatest concern was about bilateral hand tremors which, in her view became, worse after biperiden was prescribed. Therefore, she stopped taking it. The initial medication was: omeprazole, losartan, biperiden, fluoxetine, atenolol + chlorthalidone, acetylsalicylic acid, atorvastatin and diazepam. Pharmacotherapeutic follow up was performed in order to check the necessity, safety and effectiveness of treatment. Discussion: During the analysis of pharmacotherapy, the patient showed uncontrolled blood pressure and had difficulty complying with the treatment. Thus, in view of the complaints expressed by the patient, our first hypothesis was a possible serotonin syndrome related to fluoxetine use. We proposed a change in the fluoxetine regime and discontinuation of biperiden. As tremors persisted, we suggested the replacement of fluoxetine by sertraline, since a possible tremor fluoxetine-induced could explain the complaint. This approach solved the drug-related problem identified. Conclusion: Tremors reported by the patient was identified as an iatrogenic event related to fluoxetine, which was solved by management of serotonin-reuptake inhibitors.

This paper presents some outcomes of a broader research on Astronomy Education in primary school teacher's education. From the analysis of the main astronomy subjects thought nationwide and the research outcomes, we identified a set of astronomy contents considered fundamental to the teachers practice. Through a research carried out among a sample of primary school teachers, however, we show that, even in these essential contents, persists alternative conceptions among those teachers. Data collected pointed out, thus, to the necessity of improving teacher's education in this area, taking into consideration astronomy edu cation research outcomes, in favor of a teaching which contemplates, at least, the fundamental contents on this subject.

Apenas alguns relatos na literatura demonstram que lectinas são importantes nos processos de colonização e infecção por Escherichia coli. A falta de compreensão clara dos mecanismos envolvendo lectinas, no processo de colonização por E. coli, motivou a realização deste estudo para se identificar a presença de outras lectinas não descritas em E. coli. Neste trabalho, isolou-se uma proteína de 75kDa de E. coli em coluna de Sepharose, correspondente ao receptor de aerobactina férrica (IutA). A associação de IutA com virulência de cepas de E. coli é controversa, principalmente em E. coli uropatogênica (UPEC), o que levou a se avaliar a presença do gene iutA em UPECs isoladas de pacientes com infecção urinária. O gene estava presente em 38% dos isolados, sugerindo fraca associação com virulência. Devido à existência de redundância nos sistemas de captura de ferro, sugere-se, aqui, que IutA possa ser vantajosa, mas não essencial para UPEC.

We have developed a method for locating sources of volcanic tremor and applied it to a dataset recorded on Stromboli volcano before and after the onset of the February 27th 2007 effusive eruption. Volcanic tremor has attracted considerable attention by seismologists because of its potential value as a tool for forecasting eruptions and for better understanding the physical processes that occur inside active volcanoes. Commonly used methods to locate volcanic tremor sources are: 1) array techniques, 2) semblance based methods, 3) calculation of wave field amplitude. We have choosen the third approach, using a quantitative modeling of the seismic wavefield. For this purpose, we have calculated the Green Functions (GF) in the frequency domain with the Finite Element Method (FEM). We have used this method because it is well suited to solve elliptic problems, as the elastodynamics in the Fourier domain. The volcanic tremor source is located by determining the source function over a regular grid of points. The best fit point is choosen as the tremor source location. The source inversion is performed in the frequency domain, using only the wavefield amplitudes. We illustrate the method and its validation over a synthetic dataset. We show some preliminary results on the Stromboli dataset, evidencing temporal variations of the volcanic tremor sources.

It is unclear whether patients with different clinical subtypes of Parkinson disease (PD) differ in their risk of developing levodopa-induced dyskinesia (LID) and whether resting tremor is negatively correlated with this risk.
