Bacterial alginate initially consists of 1-4-linked β-D-mannuronic acid residues (M) which can be later epimerized to α-L-guluronic acid (G). The family of AlgE mannuronan C-5-epimerases from Azotobacter vinelandii has been extensively studied, and three genes putatively encoding AlgE-type epimerases have

Electron Spin Echo Envelope Modulation (ESEEM) data are reported for three gadolinium (III) chelates, Gd-EDTA, Gd-DTPA, and Gd-TTHA, in frozen D2O/CH3OD glasses. This series includes Gd-DTPA, an MRI contrast agent that is in clinical use. Three-pulse electron spin echo modulation

To define the existence of intracellular hydration caused by metabolic derangements in the excised sciatic nerves of diabetic rats quantitatively, relaxation times (T1, T2) and fraction of intracellular water content were measured with 1H-nuclear magnetic resonance (NMR) spectroscopy in normal
We wish to report the synthesis and metal complexation properties of new radionuclide chelating agents for use in nuclear medicine. The strategy includes the facile preparation of rigid analogues of DTPA and TTHA possessing an aromatic ring. The aromatic structure
Polyaminocarboxylate-based luminescent lanthanide complexes have unusual emission properties, including millisecond excited-state lifetimes and sharply spiked spectra compared to common organic fluorophores. There are three distinct sections in the structure of the luminescent lanthanide chelates: a polyaminocarboxylate backbone to bind the
