Inhibition of trichloroethylene (TCE) oxidation by the transformation intermediate carbon monoxide (CO) was evaluated with the aquifer methanotroph Methylomonas sp. strain MM2. CO was a TCE transformation intermediate. During TCE oxidation, approximately 9 mol% of the TCE was transformed to CO. CO was oxidized by Methylomonas sp. strain MM2, and when formate was provided as an electron donor, t...

Trichloroethylene (TCE) is an occupational and environmental chemical that can cause severe hepatotoxicity. While our previous studies showed that the phosphatase inhibitor SET is a key mediator of TCE-induced liver cell apoptosis, the molecular mechanisms remain elusive. Using quantitative phosphoproteomic analysis, we report here that nucleolin is a SET-regulated phosphoprotein in human liver...

Extracts of Tinospora cordifolia (TCE) have been shown to possess anti-tumor properties, but the mechanism of the anti-tumor function of TCE is poorly understood. This investigation elucidates the possible mechanism underlying the cytotoxic effects of dichlormethane extracts of TCE, after selecting optimal duration and concentration for treatment. HeLa cells were exposed to various concentratio...

Trichloroethylene (TCE) was found as a contaminant in the well supplying water to an aquatic testing laboratory. The groundwater was routinely screened by a commercial laboratory for volatile and semivolatile compounds, metals, herbicides, pesticides, and polychlorinated biphenyls using U.S. Environmental Protection Agency methods. Although TCE was the only reportable peak on the gas chromatogr...

OBJECTIVES Inconsistent epidemiological findings, debate over interpretation, and extrapolation of findings from animal studies to humans have produced uncertainty surrounding the carcinogenicity of trichloroethylene (TCE) exposure in occupational settings. We updated meta-analyses of published case-control and cohort studies exploring occupational TCE exposure and kidney cancer risk, incorpora...

1 Multi-Stage Preconcentrator/Focuser Module Designed to Enable Trace Level Determinations of Trichloroethylene in Indoor Air with a Microfabricated Gas Chromatograph T. Sukaew, E.T. Zellers, H. Chang, G. Serrano, University of Michigan, Ann Arbor, MI. Vapor intrusion of trichloroethylene (TCE) vapors into homes and workplaces from surrounding TCE-contaminated soil is a pervasive problem throug...

Fluidized-bed biological reactors (FBBRs) may be used to remove chloroethenes such as trichloroethene (TCE) from groundwater. Proper selection of FBBR aqueous growth medium, biofilm solid support media type and size, and bed charge (bed depth to column length fraction) are critical for establishing a biomass of sufficient quantity and activity to transform TCE via aerobic cometabolism, which re...

The decomposition of trichloroethylene (TCE) by non-thermal plasma was investigated in a dielectric barrier discharge (DBD) reactor with a copper rod inner electrode and compared with a plasma-catalytic reactor. The particularity of the plasma-catalytic reactor is the inner electrode made of sintered metal fibers (SMF) coated by transition metal oxides. In order to optimize the geometry of the ...

A variety of contract typologies that exist in the literature are helpful exploration different approaches contractual relations, but only when measured with right instruments. Although Transaction Cost Economics (TCE) has a distinct, high-level, and abstract typology for contracts, it still lacks measurement scale. In this paper, scale TCE (classical, neo-classical, relational contracts) was d...
