Potential to get it badly wrong as obesity epidemic takes hold The correct therapeutic dose is important for this commonly used painkiller, say the authors, because it is potentially fatal to give too high a dose; and too low a dose may result in more serious illness. The authors surveyed 45 carers and 28 community pharmacists to find out what dose of paracetamol they thought would be appropriate for an eight year old child, weighing 25, 32, or 50 kg. They also observed the doses...

Though no systemic studies have been performed, it is generally believed that genes are the most sensitive toxicological endpoints for pollutants, and are thus desirable early warning indicators of environmental risks. A recent study, however, unexpectedly found that the sensitivity of the gene expression effect for cadmium was significantly lower than the individual level chronic toxicity indicators (such as the no observed effect concentration, NOEC). Therefore, the gene expression effect...

Ranitomeya sirensis
2013-07-30 10:53:54

Ranitomeya sirensis is a species of poison dart frog that is native to Peru. It is widely known as the Sira Poison Dart Frog, or more popularly as R. lamasi. It is kept as a bet by herpetoculturists and is considered to be one of the more difficult poison dart frogs to keep due to its relative rarity and the fragile nature of its tadpoles. Like most Ranitomeya species, R. sirensis is a mildly toxic poison dart frog. Its skin secretes small amounts of pumiliotoxins which coat the frog and...

Mimic Poison Frog, Ranitomeya imitator
2013-07-29 16:30:53

The Mimic Poison Frog (Ranitomeya imitator) is a type of poison dart frog located in the north-central region of eastern Peru. Like most other Ranitomeya species, R. imitator has a mild toxicity compared to other poison dart frogs. It produces the potent pumiliotoxin B, but its small size limits the amount of poison it can secrete. Like other poison dart frogs, it does not produce toxin in captivity. It most likely gains its poison from consuming toxic insects or other invertebrates within...

Blue Poison Dart Frog, Dendrobates Azureus

The Blue Poison Dart Frog (Dendrobates azureus) is a species of poison dart frog located in the forests surrounded by the Sipaliwini savannah, which is found in southern Suriname and northern to central Brazil. This frog is widely known as the blue poison dart frog or by its Indian name, okopipi. The species name comes from the fact that it is colored azure. This medium sized frog weighs about eight grams. It grows between 3 and 4.5 centimeters long and has a typical lifespan of four to...

The Harlequin Poison Frog (Oophaga histrionica) known also as the Harlequin Poison Dart Frog, is a species of poison dart frog with a native range from Western Ecuador to the El Choco region of Colombia. The frog is usually found on the ground of tropical rain forests, amongst fallen limbs or leaf litter. O. histrionica, along with O. speciosa, produces cardiotoxins referred to as histrionicotoxins. These moderate to highly toxic compounds act as potent non-competitive antagonists of...
