Soldiers of some eusocial insects exhibit an altruistic self-destructive defense behavior in emergency situations when attacked by large enemies. The swarm-forming invasive millipede, Chamberlinius hualienensis, which is not classified as eusocial animal, exudes irritant chemicals such as benzoyl cyanide as a defensive secretion. Although it has been thought that this defensive chemical was con...

Background: Cyanide poisoning is frequently lethal, Because of the early onset of severe symptoms and difficulty in the diagnosis. Case: The case was a 29-year-old boy who collapsed suddenly after taking a bottle of beer in a bar. Samples, such as peripheral blood, stomach contents, bile fluid, urine and mouth swabs, were prepared using standard autopsy procedure and were subjected to analysis...

BACKGROUND Biodegradation of free cyanide from industrial wastewaters has been proven as a viable and robust method for treatment of wastewaters containing cyanide. RESULTS Cyanide degrading bacteria were isolated from a wastewater treatment plant for coke-oven-gas condensate by enrichment culture technique. Five strains were able to use cyanide as the sole nitrogen source under alkaline cond...

Cassava (Manihot esculenta, Crantz) roots are the primary source of calories for more than 500 million people, the majority of whom live in the developing countries of Africa. Cassava leaves and roots contain potentially toxic levels of cyanogenic glycosides. Consumption of residual cyanogens (linamarin or acetone cyanohydrin) in incompletely processed cassava roots can cause cyanide poisoning....

FERNANDEZ F., ADOLFO, JORGE GONZALEZ-QUINTANA, AND A~AURICIO RUSSEK. E$ect of low concentrations of cyanide on Qo2 of tissue slices. Am. J. Physiol. 204(2) : 314-316. 1 g63.The oxygen consumption of brain, liver, and kidney slices measured in the Warburg apparatus was not significantly depressed by concentrations of sodium cyanide of 0.2, 0.5, and 2 pg/ml. This last concentration is considered ...

Nitrosophenylhydroxylamine-ammonium (cupferron), potassium cyanide, sodium azide, ethylenediaminetetraacetate (EDTA), alpha,alpha'-dipyridyl, and o-phenanthroline were tested (1) for their ability to enhance the frequencies of chromosomal aberrations produced by x-rays in the root tip cells of the broad bean, Vicia faba, and (2) for their ability to inhibit oxygen consumption of excised roots o...

STUDY OBJECTIVE Exposure to cyanide in fires and industrial exposures and intentional cyanide poisoning by terrorists leading to mass casualties is an ongoing threat. Current treatments for cyanide poisoning must be administered intravenously, and no rapid treatment methods are available for mass casualty cyanide exposures. Cobinamide is a cobalamin (vitamin B(12)) analog with an extraordinaril...

The conventional cyanide leaching process is used to extract gold from a high copper concentrate. Because the associated minerals consume sodium in large quantities, cost of reagents and economic benefit not ideal. At same time, number tail slag are produced, which brings series environmental problems. In order solve problems caused by excessive consumption cyanogen slag, feasibility thiosulfat...

Exposure to cyanide causes a spectrum of cardiac, neurological, and metabolic dysfunctions that can be fatal. Improved cyanide antidotes are needed, but the ideal biological pathways to target are not known. To understand better the metabolic effects of cyanide and to discover novel cyanide antidotes, we developed a zebrafish model of cyanide exposure and scaled it for high-throughput chemical ...

Cause Cyanide poisoning of birds is caused by exposure to cyanide in two forms: inorganic salts and hydrogen cyanide gas (HCN). Two sources of cyanide have been associated with bird mortalities: gold and silver mines that use cyanide in the extraction process and a predator control device called the M-44 sodium cyanide ejector, which uses cyanide as the toxic agent. Most of the cyanide mortalit...
