Nanosponge Could Serve As Vaccine Against MRSA Toxins
2013-12-02 06:21:04

University of California - San Diego Nanosponges that soak up a dangerous pore-forming toxin produced by MRSA (methicillin-resistant Staphylococcus aureus) could serve as a safe and effective vaccine against this toxin. This "nanosponge vaccine" enabled the immune systems of mice to block the adverse effects of the alpha-haemolysin toxin from MRSA—both within the bloodstream and on the skin. Nanoengineers from the University of California, San Diego described the safety and efficacy of...

Anthrax Mystery Resolved
2013-11-14 15:12:09

Brett Smith for redOrbit.com - Your Universe Online For years, doctors have wondered why someone with an anthrax infection can die days after the bacteria responsible is wiped out from their body. A new study claims the toxin produced by the bacteria uses a “Trojan horse”-like method to elude the body’s natural defenses. "This remained a mystery for more than 50 years,” said study author Gisou van der Goot, a cell biologist at Switzerland's prestigious École Polytechnique...

Biophysicists Zoom In On Pore-forming Toxin

Rice University Study of melittin-based pore formation also applies to anticancer drugs A new study by Rice University biophysicists offers the most comprehensive picture yet of the molecular-level action of melittin, the principal toxin in bee venom. The research could aid in the development of new drugs that use a similar mechanism as melittin's to attack cancer and bacteria. The study appears this week in the Proceedings of the National Academy of Sciences. Melittin does its...

Nanosponges Soak Up Toxins Released By Venom And Bacterial Infections

University of California - San Diego [ Watch The Video ] Engineers at the University of California, San Diego have invented a "nanosponge" capable of safely removing a broad class of dangerous toxins from the bloodstream — including toxins produced by MRSA, E. coli, poisonous snakes and bees. These nanosponges, which thus far have been studied in mice, can neutralize "pore-forming toxins," which destroy cells by poking holes in their cell membranes. Unlike other anti-toxin...

Professor Rikard Blunck receives the Society of General Physiologists' Cranefield Award for his breakthrough Toxin proteins are genetically engineered into our food because they kill insects by perforating body cell walls, and Professor Rikard Blunck of the University of Montreal's Group for the study of membrane proteins (GÉPROM) has detected the molecular mechanism involved. In recognition of his breakthrough, he received the Traditional Paul F. Cranefield Award of the...

baudekin
  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
