Phytoremediation of nitroglycerin in smokeless powders
… phytoremediation in the removal of nitroglycerin (NG), as applied in commercial smokeless powder from soil. Double base smokeless powder was applied to soil mesocosms at rates of 0, 1.0, 5.0 and 10% (w/w). Nitroglycerin-contaminated mesocosms were seeded with oats (Avena sativa) or …

Air assessment of open burning at Radford Army Ammunition Plant
… plume and burn characteristics, the removal of nitroglycerin from the waste, the emission of metals into the air, and the modeling of pollutant emissions from open burning. The plumes generated from open burning fall well below the mixing heights. By burning at 2:30 PM and under Army …

Endothelium-independent dilation in children and adolescents
Peak brachial artery dilation post-nitroglycerin (NTG) administration occurs between 3 and 5-min in adults. The purpose of this study was to identify the time to peak dilation response to sublingual NTG (0.3 mg) in youth. Endothelium-independent dilation (EID) was measured in 198 healthy (113 …

Transcriptiome analysis of a migraine model
… Chronic hyperalgesia was modeled using a nitroglycerin treatment. The transcriptome was characterized in the trigeminal ganglia and nucleus accumbens. Samples were sequenced using the Illumina HiSeq 4000 platform to produce paired end reads of 100 bp. Opalin, Slc32a, Cacna1b, and H2-Eb2 …

Magnetic Resonance Imaging in Paediatric Coronary Vasculopathy
… using high-field MRI (3.0 Tesla) or sublingual nitroglycerin. Central aortic stiffness is increased in children after heart transplantation and a relationship between this and CAV is demonstrated. Conclusions Coronary artery lumen and vessel wall MRI can be used to follow up children after heart …

Evaluation of a Special Teaching Program with Ambulatory Cardiac Patients
… Three medications, digoxin (lanoxin), lasix, and nitroglycerin, were studied. The program for the experimental group included planned instruction and practice in self-administered medication while the patients were hospitalized.</p> <p>The program, planned by the investigator, was implemented by …

Central blood pressure
… arm cuff. -- 4. Determine the mechanism by which nitroglycerin (NTG, a drug that has relatively selective actions to lower cSBP) lowers cPP -- Pressure and in some cases combined pressure and flow velocity were acquired at the aortic root during cardiac catheterisation. Peripheral blood pressure …

Chemical Analysis, Databasing, and Statistical Analysis of Smokeless Powders for Forensic Application
… material, double and triple base powders contain nitroglycerin in addition to nitrocellulose, and triple base powders also contain nitroguanidine. Additional organic compounds, while not proprietary to specific manufacturers, are added to the powders in varied ratios during the manufacturing …

The Detection and Identification of Explosives by Canines and Chemical Instrumentation
… The compounds of interest in this study were nitroglycerin, 2,4- dinitrotoluene, diphenylamine, ethyl centralite, and di-n-butyl phthalate. Concentration changes between pre- and post-blast smokeless powder particles were determined as well as microscopic differences between pre- and …

Photoplethysmography for non-invasive measurement of bone hemodynamic responses to changes in external pressure
… occlusion, cold exposure, skin occlusion and nitroglycerin exposure were performed. Single-limb pressure chamber experiments were performed over a range of pressures from -50 to +50 mmHg to characterize the responses to changes in external pressure and to identify the predominant control …

Characterization of the MexT Regulator of the mexEF-oprN Multidrug Efflux Operon of Pseudomonas aeruginosa
… to remove nitro groups from trinitrotoluene and nitroglycerin. As nitration is a well-known result of nitrosative stress, a role for xenB (and the co-regulated mexEF-oprN and PA2813-2812-2811) in a nitrosative stress response was hypothesized and tested. Using S-nitrosoglutathione (GSNO) as a …
