Copious amounts of red saliva the Komodo dragons produce help to lubricate the food, but swallowing is still a long process (15–20 minutes to swallow a goat). A Komodo dragon may attempt to speed up the process by ramming the carcass against a tree to force it down its throat, sometimes ramming so forcefully that the tree is knocked down. [43]
Venom may also cause hypotension. [33] In some species such as the Komodo dragon and the desert monitor, venom also induces a powerful neurotoxic effect. In the latter species for instance, envenomation causes immediate paralysis in rodents (but not birds) and lesser effects of the same nature in humans. [34]
Exendin-4, which is specific for H. suspectum, has formed the basis of a class of medications for the treatment of type 2 diabetes and obesity/metabolic syndrome, known as the GLP-1 receptor agonists. In 2005, the U.S. Food and Drug Administration approved the drug exenatide (marketed as Byetta) for the management of type 2 diabetes. It is a ...
The Komodo Biosphere Reserve and National Park is situated between Flores and Sumbawa in Indonesia. It is renowned for its population of about 5,000 giant lizards, called 'Komodo dragons' (Varanus komodoensis). They exist nowhere else in the world and are of significant interest to scientists studying the theory of evolution. [1]
Pyrrolizidine alkaloidosis poisoning in the United States has remained moderately rare among humans. The most common reports are the outcome of the misuse of medicinal home remedies, or the alkaloids are present in food and drink substances such as milk and honey when the animal carriers were exposed to the toxins.
Brodifacoum is a 4-hydroxycoumarin anticoagulant, with a similar mode of action to its historical predecessors dicoumarol and warfarin.However, due to very high potency and long duration of action (elimination half-life of 20 – 130 days), it is characterised as a "second-generation" or "superwarfarin" anticoagulant.
The symptoms of poisoning are typically gastrointestinal and neurological. [18] Symptoms occur within 6–12 hours of consumption, although cases of more severe poisoning may present sooner—as little as 2 hours after ingestion. Initial symptoms are gastrointestinal, with sudden onset of nausea, vomiting, and watery diarrhea which may be ...
Domoic acid (DA) is a kainic acid-type neurotoxin that causes amnesic shellfish poisoning (ASP). [1] It is produced by algae and accumulates in shellfish, sardines, and anchovies. When sea lions, otters, cetaceans, humans, and other predators eat contaminated animals, poisoning may result.
