Conotoxins: Potential Weapons from the Sea
Cone snails are predatory marine animals that kill their prey with powerful venom. Conotoxins are a pharmacologically and chemically diverse group of toxins found in the venom. A number of species of cone snails, such as Conus geographus, are deadly to humans. Conotoxins affect numerous neurotransmitter receptors and ion channels in the body. The receptors impacted include nicotinic, adrenergic...
متن کاملEnvironmental hazards of sea-dumped chemical weapons.
Does the post-WWII burial at sea of chemical weapons still pose a human and environmental risk?
متن کاملLiving Weapons: Biological Weapons and International Security
In the summer of 1996, as a (much younger) Army infectious disease physician, I headed off to a new assignment with the US Army Medical Research Institute of Infectious Diseases (USAMRIID) at Fort Detrick, Maryland. It was a heady time to be entering the niche fi eld of biodefense. Five years before the events of 9/11 and the subsequent “Amerithrax” attacks would become an integral part of the ...
متن کاملPelagic sea snakes dehydrate at sea.
Secondarily marine vertebrates are thought to live independently of fresh water. Here, we demonstrate a paradigm shift for the widely distributed pelagic sea snake, Hydrophis (Pelamis) platurus, which dehydrates at sea and spends a significant part of its life in a dehydrated state corresponding to seasonal drought. Snakes that are captured following prolonged periods without rainfall have lowe...
متن کاملPolarized Sea Measurements at Jparc
Helicity distributions of valence quarks have been investigated in many experiments and are now well known. On the other hand, the distributions of the polarized sea are poorly known. In particular, concerning ∆ū(x), fits assuming a totally flavour symmetric sea suggest a sign opposite respect to fits based on a flavour broken sea . The situation is even more confused concerning the transversit...
