With the advance of the combinatorial chemistry, a large number of synthetic compounds have surged. However, we have limited knowledge about them. On the other hand, the speed of designing new drugs is very slow. One of the key causes is the unacceptable toxicities of chemicals. If one can correctly identify the toxicity of chemicals, the unsuitable chemicals can be discarded in early stage, th...
Hydrazine and 1,1-dimethylhydrazine are industrial chemicals that enter the environment primarily by emissions from their use as aerospace fuels and from industrial facilities that manufacture, process, or use these chemicals. Treatment and disposal of wastes containing these chemicals also contribute to environmental concentrations. These chemicals may volatilize to the atmosphere from other m...
The collapse of the World Trade Center (WTC) on 11 September 2001 exposed New York City firefighters to smoke and dust of unprecedented magnitude and duration. The chemicals and the concentrations produced from any fire are difficult to predict, but estimates of internal dose exposures can be assessed by the biological monitoring of blood and urine. We analyzed blood and urine specimens obtaine...
Background and Purpose: Poisoning with pesticides, drugs, and chemicals is one of the most important health problems in the world, causing a varying mortality rate in different regions. Easy access to a variety of drugs and poisons has caused some people to be hurt by using such things. The aim of this study was to evaluate the poisoning and mortality rate by using poisons, drugs, and chemicals...
A number of environmental chemicals, by mimicking natural hormones, can disrupt endocrine function in experimental animals, wildlife, and humans. These chemicals, called "endocrine-disrupting chemicals" (EDCs), are such a scientific and public concern that screening and testing 58,000 chemicals for EDC activities is now statutorily mandated. Computational chemistry tools are important to biolog...
