Nuclear magnetic resonance (NMR) is used for a large array of applications, ranging from chemical characterization to oil drilling to medical imaging. In these fields NMR is used as an investigational tool, but new techniques and applications are continuou ...
To study the physicochemical properties of the DTTA chelating moiety (H4DTTA = diethylenetriaminetetraacetic acid = N,N′-[iminobis(ethane-2,1-diyl)]bis[N-(carboxymethyl)glycine]), used in several compounds proposed as magnetic resonance imaging (MRI) contr ...
Three novel GdDO3A-type bismacrocyclic complexes, conjugated to Ca2+ chelating moieties like ethylenediamine-tetraacetic acid and diethylenetriamine pentaacetic acid bisamides, were synthesized as potential "smart" magnetic resonance imaging contrast agent ...
Nuclear magnetic relaxation in the presence of paramagnetic centres has gained increasing interest in recent years partly due to its importance for contrast agents in magnetic resonance imaging. Rational design of new more efficient agents is possible as a ...
Fourier domain Optical coherence microscopy (FDOCM) offers excellent sensitivity and high axial resolution to image the structure of biological tissue. The depth information is extracted in parallel and allows very high volume acquisition rates. An illumin ...
In this thesis, we intend to develop the sol-gel technology (a chemical way to make glass) from the traditional "raw" materials side to a novel technology allowing realization of innovative products in the field of micro- and nanotechnology. We first prese ...
The feasibility of using chemometric techniques for the automatic detection of whether a rabbit kidney is pathological or not is studied. Sequential images of the kidney are acquired using Dynamic Contrast-Enhanced Magnetic Resonance Imaging with contrast ...
OBJECT: Use of polyethylenimines (PEIs) of different molecular weight and selected carboxylated-PEI derivatives (PEI-COOH) in the synthesis and stabilization of iron oxide nanoparticles, to obtain possible multifunctional contrast agents. MATERIALS AND MET ...
A novel bis-hydroxymethyl-substituted DTTA chelator N¢-Bz-C4,4¢-(CH2OH)2-DTTA (1) and its DTPA analogue C4,4¢-(CH2OH)2-DTPA (2) were synthesized and characterized. A variable-temperature 1H NMR spectroscopy study of the solution dynamics of their diamagnet ...
Les établissements de santé sont perçus comme d’importantes sources d’émission de composés pharmaceutiques, désinfectants et souches microbiennes résistantes aux antibiotiques. Le but de cette étude est d’analyser l’importance des établissements de santé c ...
