terephthalic acid/inflammation

The terephthalic acid (TPA) smoke obscurants (M-83 grenade and M-8 smoke pot) were developed by the U.S. Army for training purposes to replace the more toxic hexachloroethane (HC) smoke. Inhalation toxicity testing and chemical characterization of pyrotechnically generated TPA was conducted to

Polyethylene terephthalate, a copolymer of terephthalic acid (TPA) or dimethyl terephthalate (DMT) with ethylene glycol, has food, beverage, and drinking water contact applications. Di-2-ethylhexyl terephthalate (DEHT) is a plasticizer in food and drinking water contact materials. Oral reference

During tribocorrosion of biomedical alloys, potentials may shift cathodically across the metal-oxide-electrolyte interface resulting in the increased reduction of local oxygen and water molecules. The products of reduction are thought to include reactive oxygen species (ROS) as well as hydroxide

Reactive oxygen species (ROS), such as free radicals and peroxides, are environmental trace pollutants potentially associated with asthma and airways inflammation. These compounds are often not detected in indoor air due to sampling and analytical limitations. This study developed and validated an

The purified terephthalic acid (PTA) petrochemical wastewater molecular toxicity detected by use of Mouse Genome 430A 2.0 GeneChip was conducted in this research. The toxic dose to male mice was 0.03 g/(kg x d) of PTA in the wastewater. The mice liver total RNA was isolated as the temple for

The biocompatibility of bioerodible polyanhydrides and toxicology of the polymer breakdown products were assessed. Poly-[bis (p-carboxy-phenoxy) propane anhydride] (PCPP), Poly(terephthalic acid anhydride) (PTA), and their copolymers with sebacic acid were tested. The polymers did not provoke

The inflammatory cytokine TNF-α has been recognized as a critical tumor promoter, but the effector cells that mediate its action have not been fully characterized. Because B cells regulate squamous and prostate carcinogenesis, and Tnf(-/-) mice harbor B-cell defects, we investigated the hypothesis
