This study evaluated the utility of the clearance time of inhaled diethylenetriamine pentaacetate (DTPA) to distinguish pulmonary vascular disease from early fibrosing alveolitis (FA) in patients with systemic sclerosis (SSc). It was hypothesized that this would be preserved in patients with vascular disease compared with FA, despite similar gas-transfer deficits and matching lung volumes, beca...

An electron microscopic technique, energy-dispersive x-ray (EDX) analysis, was applied to rat tissue specimens containing gadolinium diethylenetriamine-pentaacetic acid (DTPA). EDX spectroscopy was able to detect the characteristic radiation spectra of gadolinium from tissues in concentrations as low as 0.005 mmol per gram of tissue. A mapping algorithm allowed the detected spectra to be assign...

Materials and reagents The complex [PtCl(dien)]Cl (dien = diethylenetriamine) was prepared by literature methods. 1 Purity was confirmed by 1H and 195Pt NMR Spectroscopy, and Elemental Analysis (performed by QTI Laboratory, USA). All reagents were purchased from Sigma Aldrich, USA and used without further purification. The NCp7 C-terminal peptide sequence (KGCWKCGKQEHQMKDCTER) was purchased fro...

Gold(Ill) is isoelectronic (5d8) and often isostructuml (square-planar) with Pt(ll) and might form the basis of active anticancer agents [1]. However little is known about the biochemistry of Au(lll), a subject also of interest in connection with the side-effects of antiarthritic gold drugs [2]. In this work we have explored the binding of [Au(lll)(diethylenetriamine)CI]CI2 to tripeptides over ...

Abstract In this work, characterization and kinetics of CO2 absorption in potassium carbonate (K2CO3) solution promoted by diethylenetriamine (DETA) were investigated. Kinetics measurements performed using a stirred cell reactor the temperature range 303.15–323.15 K total concentration up to 2.5 kmol m?3. The density, viscosity, physical solubility, diffusivity rate determined. reaction between...
