Abstract
We characterized the F strain of herpes simplex virus-1 passaged in the presence of a natural carrageenan isolated from the red seaweed Gigartina skottbergii in view of the virulence for mice of isolated viral clones.
Viral clones (syn14-1 and syn17-2) showed a syncytial phenotype an...

Abstract
I argue that, although seawater's qualities in early anthropology were portrayed impressionistically, today technical, scientific descriptions of water's form prevail. For example, processes of globalization - which may also be called "oceanization" - are often described as "currents," "flows," and...

Abstract
Some nutritional components of the edible seaweeds Cryptonemia obovata and Rhodymenia corallina were determined. The amino acid content ranged from 1.0 +/- 0.3 to 4174.2 +/- 14.2 mg 100 g(-1) dry wt in C. obovata and between 0.9 +/- 0.3 and 2657.0 +/- 13.5 mg 100 g(-1) dry wt in R. corallina. The mo...

Abstract
An ethanol extract of fucoxanthin-rich seaweed was examined for its effectiveness as a nutraceutical for body fat-lowering agent and for an antiobese effect based on mode of actions in C57BL/6J mice. Animals were randomized to receive a semi-purified high-fat diet (20% dietary fat, 10% corn oil and...

Abstract
We show that, when protected from herbivores, approximately 40 to 70% of common seaweeds cause bleaching and death of coral tissue when in direct contact. For seaweeds that harmed coral tissues, their lipid-soluble extracts also produced rapid bleaching. Coral bleaching and mortality was limited to...
