1. MACROALGAE Fucus vesiculosus OIL: BIODIESEL PRODUCTION USING ALKALINE TRANSESTERIFICATION
This work studied the obtaining of methyl biodiesel and ethyl biodiesel using alkaline transesterification from macroalgae Fucus vesiculosos oil (FVO). FVO has 86.59% of its composition in unsaturated fatty acids, with a greater quantity of linoleic acid and oleic acid, a chemical composition near the soybean oil, the most used raw material for the productio

2. Pneumonite intersticial e miocardiopatia simultâneas induzidas por venlafaxina
A venlafaxina é um inibidor de recaptação de serotonina e noradrenalina utilizado como antidepressivo. A variabilidade individual ou interações entre fitoterápicos e fármacos podem causar toxicidade induzida por drogas. Relatamos o caso de uma paciente de 35 anos diagnosticada com pneumonite intersticial e miocardiopatia dilatada atribuídas à venlaf

3. Avaliação da qualidade microbiológica de cápsulas e chás de plantas utilizadas na assistência ao tratamento da obesidade
O uso de plantas diuréticas e laxativas é uma alternativa medicamentosa para muitas pessoas que objetivam o emagrecimento com menores efeitos adversos. A avaliação microbiológica é um requisito essencial para a garantia de qualidade dos produtos. A finalidade deste trabalho foi avaliar a qualidade microbiológica de cápsulas e chás de alcachofra (Cyn

4. Atividade antioxidante de fucanas e galactanas extraídas de algas marinhas
Estudos feitos com polissacarídeos de algas têm demonstrado que esses apresentam atividades biológicas e farmacológicas importantes. Estes compostos apresentaram atividade varredora de radicais livres, os quais são importantes na mediação do processo inflamatório e na patologia de diversas doenças. Recentemente, essa propriedade varredora tem levado

5. Efeito de frações obtidas da fucoidana de Fucus vesiculosus em modelo experimental de artrite induzida por Zymosan
The fucoidan from Fucus vesiculosus is known for having diverse biological properties. This study analyzed the therapeutic action of populations of commercial fucoidan (F. vesiculosus) on zymosan-induced arthritis. Three populations of fucoidan were obtained after acetone fractionation; these were denominated F1 (52.3%), F2 (36.7%) and F3 (10.7%). Chemical a

6. Genotoxic and antigenotoxic effects of Fucus vesiculosus extract on cultured human lymphocytes using the chromosome aberration and Comet assays
The brown seaweed Fucus vesiculosus (Fucales, Fucaceae) was screened for its protective activity using doxorubicin-induced DNA damage in human lymphocytes. In this study, we assessed the genotoxic and antigenotoxic potential of three different concentrations (0.25, 0.5 and 1.0 mg mL-1) of F. vesiculosus aqueous extract using the chromosome aberration and Com

7. Ação de polissacarídeos sulfatados de Fucus Vesiculosus na Hemostasia e no sistema complemento
Fucans are a family of sulfated homo and teropolysaccharides respectively, composed mainly of a- (12) and a- (13) linked by L-fucose residues. Properties such as the ability to act as an anti-contraceptive, to reduce cholesterol levels, and to act as an anti-tumor agent are much related. We have focused our attention on the anticoagulant properties, platelet

8. Efeito do Fucoidam de Fucus vesiculosus em um modelo experimental de artrite reumatóide
Rheumatoid arthritis (RA) is systemic auto imune disorder. It is caracterized by chronic inflammation of joints leading to progressive erosion of cartilage and bone. We investigated the effect of the administration of fucoidan, sulfated polysaccharides, from algae Fucus vesiculosus in the acute (6h) in zymosan-induced arthritis (AZy). Wistar rats (180-230 g)

10. Successful external fertilization in turbulent environments.
Mathematical and experimental simulations predict that external fertilization is unsuccessful in habitats characterized by high water motion. A key assumption of such predictions is that gametes are released in hydrodynamic regimes that quickly dilute gametes. We used fucoid seaweeds to examine whether marine organisms in intertidal and subtidal habitats mig

11. Potentiation of Photosynthetic Oxygen Evolution in Red Light by Small Quantities of Monochromatic Blue Light 1
Growth of the giant unicellular green alga, Acetabularia crenulata, stops in red light of broad spectral composition, but can be restored by the addition of small quantities of blue light. Long-term records of O2 evolution indicate that the photosynthesis of Acetabularia responds in a parallel manner to blue light. Cells photosynthesizing at a light-limited

12. Cell Wall Assembly in Fucus Zygotes: I. Characterization of the Polysaccharide Components 12
Fertilization triggers the assembly of a cell wall around the egg cell of three brown algae, Fucus vesiculosus, F. distichus, and F. inflatus. New polysaccharide polymers are continually being added to the cell wall during the first 24 hours of synchronous embryo development. This wall assembly involves the extracellular deposition of fibrillar material by c
