Researchers identify possible new therapeutic target for acetaminophen induced acute liver failure NYU School of Medicine researchers have discovered that dendritic cells in the liver have a protective role against the toxicity of acetaminophen, the widely used over-the-counter pain reliever and fever reducer for adults and children. The study's findings are published in the September issue of the journal Hepatology. The liver is the organ that plays a central role in transforming and...
A new saliva test can measure the amount of potential carcinogens stuck to a person's DNA — interfering with the action of genes involved in health and disease — and could lead to a commercial test to help determine risks for cancer and other diseases, scientists reported here today during the 242nd National Meeting & Exposition of the American Chemical Society (ACS). "The test measures the amount of damaged DNA in a person's body," said Professor Hauh-Jyun Candy Chen, Ph.D., who...

GIA announces the release of a comprehensive global report on the ADME-Tox Technologies markets. Driven by the rising costs in new drug discovery and development and the large proportion of drug failure associated with ADME-Tox issues, ADME-Tox technologies market is witnessing a robust growth as pharmaceutical and biotech companies adopt new technologies and ADME-Tox screening at an early stage of drug discovery and development. Spurred by these developments, the global ADME-Toxicology...
Baylor researchers develop new method for Europe’s REACH regulation Baylor University environmental researchers have proposed in a new study a different approach to predict the environmental safety of chemicals by using data from other similar chemicals. For many chemicals in use every day, scientists do not have enough information to understand all of the effects on the environment and human health. In response to this, the European Union enacted the REACH regulation, which places...

Cadmium is a chemical element in the periodic table that has the symbol Cd and atomic number 48. A relatively rare, soft, bluish-white, toxic transition metal, cadmium occurs with zinc ores and is used largely in batteries. Notable characteristics Cadmium is a soft, malleable, ductile, bluish-white bivalent metal which can be easily cut with a knife. It is similar in many respects to zinc but lends itself to more complex compounds. The most common oxidation state of cadmium is +2,...
