The discovery of the first enzyme in the pathway sheds new light on the evolution of alkaloid formation Humans encounter alkaloids every day Alkaloids constitute a very large group of natural nitrogen-containing compounds with diverse effects on the human organism. A large variety of plant-produced alkaloids have strong pharmacological effects, and are used as toxins, stimulants, pharmaceuticals or recreational drugs, including caffeine, nicotine, morphine, quinine, strychnine, atropine...

The brain is forever chattering to itself, via electrical impulses sent along its hard-wired neuronal "Ethernet." These e-messages are translated into chemical transmissions, allowing communication across the narrow cleft separating one neuron from another or between neurons and their target cells. Of the many kinds of molecules involved in this lively chemical symposium, acetylcholine is among the most critical, performing a host of functions in the central and peripheral nervous system....

A study published this week in the open access journal PLoS Medicine finds no evidence to suggest that a controversial antidote recommended by the World Health Organisation (WHO) to treat patients poisoned with highly toxic insecticides improves their chance of survival. The results may even add weight to existing concerns about pralidoxime, the treatment recommended by the WHO, by suggesting that it could be harmful in patients who have deliberately poisoned themselves with...

By Bar-Meir, Eran; Schein, Ophir; Eisenkraft, Arik; Rubinshtein, Ronen; Et al Organophosphate poisoning may precipitate complex ventricular arrhythmias, a frequently overlooked and potentially lethal aspect of this condition. Acute effects consist of electrocardiographic ST- T segment changes and AV conduction disturbances of varying degrees, while long-lasting cardiac changes include QT prolongation, polymorphic tachycardia ("Torsades de Pointes"), and sudden cardiac death. Cardiac...

By Anthony J. Brown, MD NEW YORK (Reuters Health) - Treatment with galantamine, a drug used to treat Alzheimer's disease, in combination with atropine, protects guinea pigs from lethal doses of the nerve agents sarin and soman and the insecticide parathion, new research shows. The toxic effect of these "organophosphorus" compounds derives from irreversible blockage of an enzyme critical to nerve function. The end result can be seizures and cardiac arrest. At present, atropine and...

By Maggie Fox, Health and Science Correspondent WASHINGTON (Reuters) - An Alzheimer's pill that helps slow the brain damage caused by the disease may also protect against the effects of nerve gases and pesticides, U.S. researchers reported on Monday. They said the drug, marketed under the name Reminyl and Razadyne, completely protected guinea pigs against the nerve agents soman and sarin, as well as toxic amounts of pesticides. They gave the animals high doses of the poisons and...

DENVER (Reuters) - Autopsy results of San Francisco 49ers tackle Thomas Herrion revealed that the 23-year-old died of a heart attack, the Denver coroner's office said on Tuesday. "Mr. Herrion had significant blockage of his right coronary artery. This blockage had caused death of heart muscle, indicated by healing and scarring," Nancy Severson of the Denver Department of Health said in a written statement. Herrion's heart was slightly enlarged, and blood and urine toxicology results...
