Contaminant Hepatotoxins as Culprits for Kava Hepatotoxicity – Fact or Fiction?
Phytotherapy Research, 2013 The culprit of kava hepatotoxicity will continue to remain a mystery in humans, if the underlying reaction is of idiosyncratic, unpredictable, and dose-independent nature due potentially to some metabolic aberration in a few individuals emerging from ...

Global Warming and Hepatotoxin Production by Cyanobacteria: What Can We Learn From Experiments?
Water Research, 2012 Global temperature is expected to rise throughout this century, and blooms of cyanobacteria in lakes and estuaries are predicted to increase with the current level of global warming.

Physico-Chemical Treatment Methods for the Removal of Microcystins (Cyanobacterial Hepatotoxins) From Potable Waters [PDF]
Chemical Society Reviews, 1999 The incidence of cyanobacterial blooms in freshwaters, including drinking water reservoirs, has increased over the past few decades due to rising nutrient levels. Microcystins are hepatotoxins released from cyanobacteria and have been responsible for the

Water Research, 1989 The behaviour of hepatotoxins fromMicrocystis andOscillatoria cyanobacteria in some common water treatment processes was investigated on the laboratory scale in order to obtain data on their potential transfer to drinking water. Two toxins were separated

Digestive Diseases, 2008
Although essential for life, iron in excessive amounts may be toxic. The liver is particularly subject to the toxic effects of iron, since it is the major site of iron storage. Several inherited and acquired human disorders may result in hepatic iron overload, the most common of which are genetic hemochromatosis (GH) and transfusional iron overload. GH

Investigations into a Hepatotoxin in Lupin Roughage
Research in Veterinary Science, 1970Preliminary investigations into the chemical nature of a hepatotoxic factor which sometimes occurs in dried lupin roughage, particularly in Western Australia, have been carried out. Results indicated it was not an alkaloid. Its properties suggested the presence of phenolic and/or acidic groups.

Detection of the cyanobacterial hepatotoxins microcystins
Toxicology and Applied Pharmacology, 2005Concern regarding the presence of microcystins in drinking water and their possible contamination in food (e.g., salad vegetables, fish, shellfish) has resulted in the need for reliable methods for the detection and accurate quantification of this class of toxins.

Removal of a potent cyanobacterial hepatotoxin by peat
Journal of Environmental Science and Health, Part A, 2010Microcystins (cyclic heptapeptides), produced by a number of freshwater cyanobacteria, are of health concern in potable water supplies. In this article, the adsorptive removal of microcystin-RR (MCRR) from the aqueous solution by a low-cost adsorbent, peat, was investigated. The BET surface area of peat was found to be 12.134 m2/g.

Are Mould Hepatotoxins Responsible for Kava Hepatotoxicity?
Phytotherapy Research, 2012Previous studies with kava components such as kavalactones, pipermethystine and flavokavain B have demonstrated hepatotoxicity from these constituents. Regardless, there has recently been speculation that adulterants or impurities such as the mould hepatotoxin aflatoxin are a more likely cause of kava hepatotoxicity, despite a paucity of supporting ...
