Structural characterization of cold extracted fraction of soluble sulfated polysaccharide from red seaweed Gracilaria birdiae
Nutritive and non-nutritive attributes of washed-up seaweeds from the coast of Ceará, Brazil.
Induction and inhibition of human lymphocyte transformation by the lectin from the red marine alga Amansia multifida
The dose-dependent proliferative curve for human peripheral blood monouclear cells (PBMC) stimulated by the lectin amansin, from Amansia multifida is reported, and analysis of the culture supernatants established a direct correlation between the IFN-γ and the mitogenic and anti-mitogenic capacity of amanin.

Aqueous protein extracts from 30 Brazilian marine algae were examined for haemagglutinating activity using native and enzyme-treated rabbit, chicken, sheep and human erythrocytes and only the activity present in the green alga Cauler pacupressoides was inhibited by simple sugars and not by the glycoproteins tested.

Protein extracts of three species were subjected to haemagglutination inhibition studies performed with a selection of sugars or glycoproteins, and the activity of Adenocystis utriculares extracts was the only one inhibited by simple sugars.

The results suggest that Gracilaria birdiae have functional properties and consequently may be used as a source of nutraceutical and as nutritional supplements.
Analysis of new isolates reveals new genome organization and a hypervariable region in infectious myonecrosis virus (IMNV).
A new process for nauplius production of the freshwater fairy-shrimp Dendrocephalus brasiliensis (Pesta, 1921) and the effect of enzymatic and chemical treatment on hatching
Antioxidant Sulfated Polysaccharide from Edible Red Seaweed Gracilaria birdiae is an Inhibitor of Calcium Oxalate Crystal Formation
The potential application of galactan extracted from G. birdiae is highlighted as an antiurolithic agent for urolithiasis and shows no cytotoxic effect against human kidney cells (HEK-293).
