Antibacterial coatings cut infection rates

... surfaces clean when placed on those surfaces in a marine environment. This provided the impetus for studying their use in biomedical device applications," Professor Griesser said. Furanones have a unique advantage in that they act differently to other antibiotics. Unlike antibiotics, they don't kill bact...

Overfishing in inland waters reduces biodiversity and threatens health

...osystems are by some accounts more threatened than marine ecosystems. Fishing is a crucial source of livelihoods in developing nations, and in 2000 constituted an estimated 15.3 percent of human consumption of animal protein. About 1 billion people rely on fish as their primary protein source. Landings fro...

Eisai announces Phase II data on E7389, a potential new therapy for the treatment of breast cancer

...ichondrin B was originally isolated from a type of marine sponge. This study was designed to evaluate E7389 as a monotherapy in patients with refractory breast cancer. The primary endpoint of this trial was response rate, measured using the RECIST (Response Evaluation Criteria In Solid Tumors) criteria ?a ...
