Botulinum toxin (BoNT), being the most poisonous substance poses a great threat to global public health as a deadly bio-weapon. BoNT/A, BoNT/B and BoNT/E serotype toxicity cause flaccid paralysis in human by blocking neurotransmitter activity. Thearubigin, a black tea extract is found to be effective in neutralizing BoNT when experimented with animal models. This hypothesis opens a new frontier...

The new edition lias been very largely revised and rewritten, and there are ample appendices on anatomical and physiological normals, and full details are given of many laboratory tests, which have been accepted as being of practical value. The first nine chapters, about 135 pages, are devoted to bacteriology from the laboratory side ; then follow others on moulds, the bacteriology of air. wate...

The word POISON too often creates fear when it should suggest a warning. Many chemicals or common household substances used incorrectly, usually in the wrong quantity, can cause illness or even death; this is also true with certain plants. Left alone they are harmless. Bruised, crushed, or eaten in varying quantities, they may provoke effects which are upsetting, painful, or even fatal to man.

We present practical poisoning and name-server blocking attacks on standard DNS resolvers, by off-path, spoofing adversaries. Our attacks exploit large DNS responses that cause IP fragmentation; such long responses are increasingly common, mainly due to the use of DNSSEC. In common scenarios, where DNSSEC is partially or incorrectly deployed, our poisoning attacks allow ‘complete’ domain hijack...

AMONG THE ANIMALS that live in the sea are many that may be poisonous to eat; these animals include fish, sharks , crabs, molluscs, and turtles. Of all marine animals the most important are fish, which are for so many people an essential source of food. There are a number of different ways in which teleost fish may be poisonous. Some fish are naturally poisonous; puffers for instance are always...

Agriculturally grown plants are potentially contaminated with poisonous weeds. Many potentially toxic plants are found in pastures and crops. Consequently, forage crops at harvest or when directly grazed may contain toxic amounts of poisonous plants. Unfortunately, efficient prevention of contamination with certain poisonous plants is not always feasible or practical, and thus, contaminated fee...
