Snake venoms and their toxins: an Australian perspective.
Australia is home to a vast collection of highly venomous terrestrial and marine snakes. As such, Australia has proven to be an excellent source of investigative material for both local and international toxinologists. Research on snake venoms initially focussed on identifying the most lethal species, and the venom components responsible for the lethality, so that treatment strategies could be ...

be explored. Darwin claims to have agonized over the evolution of the eye and much is made of the actual ease of its evolution in terms of dioptrics. Less often is it remembered that the hallmarks of any eye, its transparency and transduction mechanisms, depend on proteins (respectively crystallins and opsins) that evolved long before there were any eyes. And this molecular inherency underpins ...
متن کاملSnake toxins from mamba venoms: unique tools for the physiologist.
Snake venoms are complex mixtures of small molecules, peptides and proteins. Most of the biologically active toxins are peptides or enzymes. The peptides belong to several structural classes, and they have many different biological actions. The best characterised are the so-called three-finger toxins that have three peptide loops stabilised by four disulphide bridges. Despite their common 3D sh...

متن کاملToxins and Antitoxins of Bacillus Dysenteriæ Shiga
With the methods which have been described we have separated an exotoxin and an endotoxin from cultures of the Shiga dysenteric bacillus. The study of the nature and effect of the poison of this microorganism is thus simplified. The two toxins are physically and biologically distinct. The exotoxin is relatively heat-labile, arises in the early period of growth, and yields an antiexotoxic immune...
