Three terrestrial plant species, oat (Avena sativa ), Chinese cabbage (Brassica campestris cv. chinensis) and lettuce (Lactuca sativa), were exposed to different concentrations of herbicide TCA (sodium trichloroacetate) in a growth test according to guideline OECD # 208. Classical (i.e. germination and biomass) and biochemical (i.e., antioxydant enzyme activities) endpoints were investigated. G...

In 2004, the United States Preventive Services Task Force (USPSTF) gave testicular cancer (TCa) screening a 'D' recommendation, discouraging the use of this preventive service. The USPSTF suggested that screening, inclusive of testicular self-examination (TSE) and clinician examination, does not reduce TCa mortality rates and that the high risk of false positives could serve as a detriment to p...

BACKGROUND Transplant coronary arteriosclerosis (TCA) is the principal long-term complication in cardiac transplant recipients. The mediators responsible for vascular proliferation and vasoconstriction typical of TCA remain largely unknown. We tested whether endothelin-1 (ET-1), a potent vasoconstrictor and mitogen, contributes to the pathogenesis and manifestations of TCA. METHODS AND RESULT...

This study was done to characterize the structural changes in the tretinoin pretreatment on trichloroacetic acid(TCA) chemical peel. In guinea pigs, the right halves pretreated with tretinoin and the left halves treated nothing were compared in their structural changes after TCA chemical peel. Epidermal thickness in the tretinoin pretreated group was almost the same in the first and second week...

For many people, trade is about goods and so the most momentous aspect of Trade Cooperation Agreement (TCA) provisions on goods. This article looks at in under TCA compares them with those Customs Union Single Market for EU law (which still apply to Northern Ireland Ireland/Northern Protocol). It argues that approach movement has much more common World Organization's (WTO) goods, which draws he...

A field study was performed to evaluate the potential for in-situ aerobic cometabolism of 1,1,1-trichloroethane (1,1,1-TCA) through bioaugmentation with a butane enrichment culture containing predominantly two Rhodococcus sp. strains named 179BP and 183BP that could cometabolize 1,1,1-TCA and 1,1-dicholoroethene (1,1-DCE). Batch tests indicated that 1,1-DCE was more rapidly transformed than 1,1...

The trichloroacetic acid (TCA)-insoluble fraction of water column bacteria labeled with [H]leucine contained an ethanol-soluble fraction accounting for up to 44% of the label. A component of the ethanol-soluble fraction is [H]leucine. Labeled-protein purification requires an ethanol wash step. Cold TCA can replace hot TCA for precipitation of labeled proteins.
