Biodiesel: an overview
The importance of biodiesel production was analyzed based on scientific articles and patents. A critical analysis was presented on the most used oil sources, the catalysts and the methods to verifyExpand
Antimicrobial activity of Brazilian copaiba oils obtained from different species of the Copaifera genus.
Transmission electron microscopy of S. aureus treated with resin oil from C. martii revealed disruption and damage to the cell wall, resulting in the release of cytoplasmic compounds, alterations in morphology, and a decrease in cell volume, indicating that copaiba oil may affect the cell walls.

Chemical composition and anti-inflammatory activity of copaiba oils from Copaifera cearensis Huber ex Ducke, Copaifera reticulata Ducke and Copaifera multijuga Hayne--a comparative study.
The Copaiba Oil from Copaifera multijuga Hayne (100 mg/kg) was the most potent, inhibiting both NO production and the pleurisy induced by zymosan, and the oleoresins from CopAifera cearensis Huber ex Ducke and Copaifiera reticulata Ducke were also able to inhibit NOProduction and the Pleurisy but with less intensity.

Effect of Brazilian copaiba oils on Leishmania amazonensis.
Cytotoxicity assay showed that this copaiba oil obtained from Copaifera reticulata showed low cytotoxicity against J774G8 macrophages, indicating significant activity against the parasite Leishmania amazonensis. Expand
Interactions between irrigants commonly used in endodontic practice: a chemical analysis.
The orange-brown precipitate observed in the association between CHX and NaOCl occurs because of the presence of NaO Cl, an oxidizing agent causing chlorination of the guanidino nitrogens of the CHX. Expand
Plantas medicinais: a necessidade de estudos multidisciplinares
This paper presents a program emphasizing ethnopharmacological approaches that could allow great success in the study of medicinal plants. The minimum ethnopharmacological research team shouldExpand
In vivo and in vitro studies on the anticancer activity of Copaifera multijuga hayne and its fractions
The action of COR and its fractions on the inhibition of lung metastasis and tumour growth induced by B16F10 melanoma cells in mice and cytotoxicity in vitro is evaluated using Trypan Blue exclusion method and MTT conversion. Expand
Isatins inhibit cyclooxygenase-2 and inducible nitric oxide synthase in a mouse macrophage cell line.
The results indicate isatin and it derivatives as inhibitors of iNOS and COX-2 enzymes, which might be used as anti-inflammatory and antitumoral agents. Expand
The Role of Additives for Diesel and Diesel Blended (Ethanol or Biodiesel) Fuels: A Review
Around the world, there is a growing increase in biofuels consumption, mainly ethanol and biodiesel as well as their blends with diesel that reduce the cost impact of biofuels while retaining some ofExpand
Anti-inflammatory and analgesic activities of the latex containing triterpenes from Himatanthus sucuuba.
Among all the fractions studied, the fraction containing only cinnamates showed the greatest anti-inflammatory activity which suggests that these compounds were responsible for the previously described activity of the crude extract. Expand
