In this study, a rationally-designed 2,4,6-trinitrotoluene (TNT) binding peptide derived from an amino acid sequence of the complementarity-determining region (CDR) of an anti-TNT monoclonal antibody was used for TNT detection based on a maleimide-functionalized surface plasmon resonance (SPR) sensor. By antigen-docking simulation and screening, the TNT binding candidate peptides were obtained ...

Because of its high electron deficiency, initial microbial transformations of 2,4,6-trinitrotoluene (TNT) are characterized by reductive rather than oxidation reactions. The reduction of the nitro groups seems to be the dominating mechanism, whereas hydrogenation of the aromatic ring, as described for picric acid, appears to be of minor importance. Thus, two bacterial strains enriched with TNT ...

Pseudomonas pseudoalcaligenes JS52 grows on nitrobenzene via partial reduction of the nitro group and enzymatic rearrangement of the resultant hydroxylamine. Cells and cell extracts of nitrobenzene-grown JS52 catalyzed the transient formation of 4-hydroxylamino-2,6-dinitrotoluene (4HADNT), 4-amino-2,6-dinitrotoluene (4ADNT), and four previously unidentified metabolites from 2,4,6-trinitrotoluen...

Extensive biodegradation of TNT (2,4,6-trinitrotoluene) by the white rot fungus Phanerochaete chrysosporium was observed. At an initial concentration of 1.3 mg/liter, 35.4 +/- 3.6% of the [14C]TNT was degraded to 14CO2 in 18 days. The addition of glucose 12 days after the addition of TNT did not stimulate mineralization, and, after 18 days of incubation with TNT only, about 3.3% of the initial ...

We aimed to determine the prognostic value of troponin T (TNT) for in-hospital and 1-yr mortality in a large sample of patients with pulmonary embolism (PE). Patients presenting at the emergency department of a tertiary care centre from January 1998 to December 2006 with PE were included. A blood sample was taken at the time of presentation. To determine in-hospital and 1-yr mortality, data fro...

Cardiac biomarkers provide prognostic information in light-chain amyloidosis (AL). Thus, a novel high-sensitivity cardiac troponin T (hs-TnT) assay may improve risk stratification. hs-TnT was assessed in 163 patients. Blood levels were higher with cardiac than renal or other organ involvement and were related to the severity of cardiac involvement. Increased sensitivity was not associated with ...

To achieve sustainable range management and avoid or minimize environmental contamination, the Army needs to know the amount of explosives deposited on ranges from different munitions and how these are degraded and transported under different geological and climatic conditions. The physical form of the deposited explosives has a bearing on this problem, yet the shapes and size distributions of ...

BACKGROUND The mechanisms explaining morphological electrocardiogram (ECG) changes and increased troponin T (TnT) in acute stroke are unclear. The aims of the present study were to assess the prevalence of ECG and TnT changes in acute ischaemic stroke, to investigate whether ischaemic-like ECG changes correlate to a rise in TnT and to examine whether ECG changes and elevated TnT predict a poor ...
