14. Fucoidan induces G1 arrest of the cell cycle in EJ human bladder cancer cells through down-regulation of pRB phosphorylation
AbstractFucoidan, a sulfated polysaccharide found in marine algae and brown seaweeds, has been shown to inhibit the in vitro growth of human cancer cells. This study was conducted in cultured human bladder cancer EJ cells to elucidate the possible mechanisms by which fucoidan exerts its anti-proliferative activity, which until now has remained poorly underst

15. The red seaweed Plocamium brasiliense shows anti-snake venom toxic effects
Background Snakebite is considered a neglected tropical disease by the World Health Organization. In Brazil, about 70% of the envenomation cases are caused by Bothrops snakes. Its venom may provoke hemorrhage, pain, necrosis, hemolysis, renal or cardiac failure and even death in victims. Since commercial antivenom does not efficiently neutralize the local t

16. Antioxidant properties of some filamentous green algae (Chaetomorpha Genus)
The antioxidant activity and the contents of total phenolics and flavonoids were quantified in the methanolic extracts of four Chaetomorpha species including C. aerea, C. crassa, C. linum and C. brachygona. Eight samples of Chaetomorpha plants were collected from five locations along the northern coasts of the Persian Gulf in south of Iran from December 2010

17. Antiulcer, wound healing and hepatoprotective activities of the seaweeds Gracilaria crassa, Turbinaria ornata and Laurencia papillosa from the southeast coast of India
Algas marinhas possuem compostos bioativos de interesse para a indústria farmacêutica. Na Índia, as algas marinhas são usadas exclusivamente para a produção de ficocolóides e ainda não receberam a consideração como um suplemento dietético. Assim, tornou-se imperativo explorar o potencial biomédico de algas e promover a sua utilização como alime

18. Role of the NO/K ATP pathway in the protective effect of a sulfated-polysaccharide fraction from the algae Hypnea musciformis against ethanol-induced gastric damage in mice
Seaweeds are the most abundant source of polysaccharides such as alginates and agar, as well as carrageenans. This study aimed to investigate the gastroprotective activity and the mechanism underlying this activity of a sulfated-polysaccharide fraction extracted from the algae Hypnea musciformis (Wulfen) J.V. Lamour. (Gigartinales-Rhodophyta). Mice were trea

19. Seaweeds extracts as antioxidants and antimicrobial agents and their effects on quality of tilapia Minced (Oreochromis niloticus) / Extratos de algas marinhas como agentes antioxidantes e antimicrobianos e seus efeitos na qualidade de Minced de tilápia (Oreochromis niloticus)
A extração de Carne Mecanicamente Separada de tilápia tem se destacado como um processo atraente pela possibilidade de maior recuperação da carne após a filetagem. Porém, a separação mecânica aumenta a superfície de exposição, levando à incorporação de oxigênio e consequentemente ao \"off flavor\" devido à rancidez, tornando necessário o u

20. Polissacarídeos da alga marinha lithothamnion muelleri: obtenção, caracterização química e atividade antiartrítica
Marine organisms are a promising source of bioactive compounds, including red seaweeds, which are known to produce sulfated polysaccharides with different biological properties. The aim of this study was to obtain and characterize polysaccharide-rich fractions of the marine red alga Lithothamnion muelleri Lenormand ex Rosanoff (Hapalidiaceae), as well as to
