Researchers at the University of Illinois report that a toxic molecule known to damage cells and cause disease may also play a pivotal role in bird migration. The molecule, superoxide, is proposed as ...

... indocyanine green, is harmless to humans and inactive in the dark. However, it gives off toxic molecules that rapidly kill the bacteria when it is triggered by the right light wavelengths.
"The ...
... greater production of superoxide. It reacts with nitric oxide to create peroxynitrite, a very toxic molecule that can impact DNA replication and damage endothelial cells in the vascular system.
" ...
... oxidase, which is expressed primarily by microglia (immune system cells) in the brain and produces toxic molecules that can damage brain cells. To determine if shutting down this enzyme will reduce ...
... results show that some organisms actually live longer when their ability to clean themselves of this toxic molecule buildup is partially disabled. Collectively, these molecules are known as reactive ...
... blood cells called neutrophils fight infection by swarming toward bacteria to engulf and destroy them with toxic molecules. Because these same molecules also damage human cells, this ...

"How you choose to manipulate the function of oct3 depends on the source of the toxic molecules," said Tieu, who is also a scientist in the University's Center for Neural Development and Disease. " ...
... in Lyon decided to use the reaction of a group of micro-organisms to the presence of toxic molecules in evaluating the ecological status of a river and thus develop bioindicators based not on species ...
... into harmful superoxides, which ultimately harm our muscles. Specifically, these superoxides lead to the creation of a toxic molecule called "reactive oxygen species" or ROS, which is shown to be ...

The investigators report that the concentration in blood of amyloid beta "42," the toxic molecule that is believed to be the main cause of Alzheimer's disease, is, on average, higher in ...
... enters into the brain and blocks the activity of the p21Ras protein and other associated toxic molecules, and goes on to protect the neurons, normalize neurotransmitter levels, and improves the motor ...
... or Tlr4) at the surface of blood cells, including a particularly "angry" class of macrophages known to pump out toxic molecules and spur inflammation. It now appears that fatty acids ...
... : "We suspect that TmpL may act as a detoxifier of intracellular reactive oxygen species. These toxic molecules are highly elevated in the fungus at the initial stages of infection and during various ...
