2,4,6-trinitrotoluene (TNT) is a common component of many explosives. The overproduction and extensive usage of TNT significantly contaminates the environment. TNT accumulates in soils and aquatic ecosystems and can primarily be destroyed by microorganisms. Current work is devoted to investigation of Yarrowia lipolytica proteins responsible for TNT transformation through the pathway leading to ...

Munitions wastes such as TNT are widespread contaminants in soils and ground waters. We investigated a coupled abiotic-biotic treatment scheme for remediation of aqueous solutions of TNT. Mineralization of aqueous TNT (0.22 mM) was initially optimized with minimum reactant use (Fe3+ and H2O2) in light-assisted and dark, modified Fenton reactions at acidic and neutral pH. Complete TNT degradatio...

The present study was aimed at providing data to be used at predicting exposure-based effects of 2,4,6-trinitrotoluene (TNT) aged in soil on endpoint organisms representing two trophic levels. These data can be used to define criteria or reference values for environmental management and conducting specific risk assessment. Long-term exposure tests were conducted to evaluate sublethal toxicity a...

Tunneling nanotubes (TNT) are dynamic connections between cells, which represent a novel route for cell-to-cell communication. A growing body of evidence points TNT towards a role for intercellular exchanges of signals, molecules, organelles, and pathogens, involving them in a diverse array of functions. TNT form among several cell types, including neuronal cells, epithelial cells, and almost a...

INTRODUCTION AND OBJECTIVE The usefulness of prolonged troponin-T (TnT) monitoring in outpatients with nonischemic heart failure (HF) is not clear. The aim of this study was to investigate the incidence, prognostic value and determinants of a raised TnT level. METHODS The study involved 80 outpatients (age 56+/-14 years, 69% male) with chronic stable HF (mean left ventricular ejection fractio...

Under anoxic conditions Pseudomonas sp. strain JLR11 can use 2,4, 6-trinitrotoluene (TNT) as the sole N source, releasing nitrite from the aromatic ring and subsequently reducing it to ammonium and incorporating it into C skeletons. This study shows that TNT can also be used as a terminal electron acceptor in respiratory chains under anoxic conditions by Pseudomonas sp. strain JLR11. TNT-depend...

The main contaminant at many military sites is 2,4,6trinitrotoluene (TNT). This explosive remains stable in the environment, and because it is toxic, there is an urgent need for remediation to clean up contaminated sites. Pseudomonas sp. JLR11 is a soil isolate able to use nitrate, TNT, or both as the N source under anaerobic conditions. At least two polypeptides were detected in cell-free extr...

Fetal rat skeletal muscles express a troponin T (TnT) isoform similar to the TnT isoform expressed in the embryonic heart with respect to electrophoretic mobility and immunoreactivity with cardiac TnT-specific monoclonal antibodies. Immunoblotting analyses reveal that both the embryonic and the adult isoforms of cardiac TnT are transiently expressed during the neonatal stages. In addition, othe...

TnT is an efficient statistical Parts-of-speech (POS) Tagger based on Hidden Markov Model. TnT performs well on known word sequences. But, the performance degrades with increase in the number of unknown words. In this paper, we propose a method to overcome this performance degradation using fuzzy rules. Fuzzy rule based model is designed to provide TnT with sufficient information about the tag ...

The exposure of Chlamydomonas reinhardtii to environmental stress, such as that caused by the explosive 2,4,6-trinitrotoluene (TNT) can alter its gene expression. Expression analysis was conducted using a microarray composed of 3079 Chlamydomonas ESTs to characterize the broad range of responses of gene expression exposed to this common ordnance compound. TNT treatment conditions were determine...
