William Slikker et al.
Toxicology and applied pharmacology, 201(3), 226-294 (2004-12-08)
Experience with dose response and mechanisms of toxicity has shown that multiple mechanisms may exist for a single agent along the continuum of the full dose-response curve. It is highly likely that critical, limiting steps in any given mechanistic pathway
Young Kim et al.
Biotechnology and bioengineering, 80(5), 498-508 (2002-10-02)
Batch kinetic and inhibition studies were performed for the aerobic cometabolism of 1,1,1-trichloroethane (1,1,1-TCA), 1,1-dichloroethylene (1,1-DCE), and 1,1-dichloroethane (1,1-DCA) by a butane-grown mixed culture. These chlorinated aliphatic hydrocarbons (CAHs) are often found together as cocontaminants in groundwater. The maximum degradation

A feasibility study was conducted using slags from six grey-iron foundries to evaluate their potential as reactive media for permeable reactive barriers (PRBs) to remove aqueous trichloroethylene (TCE) from groundwater. Batch tests indicated that the slags exhibit varying degrees of
Keith A Canada et al.
Journal of bacteriology, 184(2), 344-349 (2001-12-26)
Trichloroethylene (TCE) is the most frequently detected groundwater contaminant, and 1-naphthol is an important chemical manufacturing intermediate. Directed evolution was used to increase the activity of toluene ortho-monooxygenase (TOM) of Burkholderia cepacia G4 for both chlorinated ethenes and naphthalene oxidation.
Erik J Martin et al.
The Journal of pharmacology and experimental therapeutics, 313(1), 95-103 (2005-01-01)
1,1-Dichloroethylene (DCE) causes pulmonary injury that is characterized by necrosis of bronchiolar Clara cells. Mitochondria have been identified as an early target in the toxic response. Because mitochondria have been implicated in both necrotic and apoptotic cell death, we have
