Nature, distribution and origin of polycyclic aromatic hydrocarbons (PAHs) in the sediments of Olbia harbor (Northern Sardinia, Italy).
TLDR
The nature, origin and distribution of US EPA polycyclic aromatic hydrocarbons (PAHs) in the sediments of Olbia harbor were investigated by gas-chromatography/mass spectrometry and good linear correlations were found between a selected PAH (Phen and Naph) and selected sums of PAHs.
Polycyclic aromatic hydrocarbons assessment in the sediments of the Porto Torres Harbor (Northern Sardinia, Italy)
The distribution of polycyclic aromatic hydrocarbons (PAHs) in the sediments of Porto Torres Harbor (north Sardinia, Italy) was investigated by gas chromatography/mass spectrometry (GCMS). PAHs
Copper(II) complexes of oligopeptides containing aspartyl and glutamyl residues. Potentiometric and spectroscopic studies.
Copper(II) complexes of di-, tri- and tetra-peptides built up from Asp and/or Glu residues were studied by potentiometric and various spectroscopic techniques including UV-visible, circular dichroism
Copper(II) interaction with prion peptide fragments encompassing histidine residues within and outside the octarepeat domain: speciation, stability constants and binding details.
TLDR
A 31-mer polypeptide, which encompasses residues 84-114 of human prion protein HuPrP(84-114) and contains three histidyl residues, revealed a high Cu2+-binding affinity of all peptides, and the spectroscopic studies made it possible to clarify the coordination mode of the peptides in the different complex species.
Equilibrium studies on copper(II)- and iron(III)-monohydroxamates
Abstract Chelating properties exhibited by a series of monohydroxamic acids toward copper(II) and iron(III) ions were studied by pH-metric, spectrophotometric and EPR methods. The ligands can be
Ternary complex formation between VO(IV)-picolinic acid or VO(IV)-6-methylpicolinic acid and small blood serum bioligands.
TLDR
The results obtained on the ternary systems reveal that mixed ligand complex formation is favoured in these systems, especially with citrate, and must therefore be taken into account in the speciation description of VO(IV) in blood serum.
Oxovanadium(IV) complexes of quinoline derivatives
Abstract Complex formation between oxovanadium(IV) and five quinoline derivatives, 8-hydroxyquinoline (8-HQ), 8-hydroxyquinoline-5-sulphonic acid (8-HQS), 2-methyl-8-hydroxyquinoline (8-HQD),
Complexes of 3,4-dihydroxyphenyl derivatives. X: Copper(II) complexes of chlorogenic acid and related compounds
The interactions of copper(II) with chlorogenic acid [1,3,4,5-tetrahydroxycyclohexanecarboxylic acid 3-(3,4-dihydroxycinnamate)] and related compounds such as 3,4-dihydroxyphenylacetic acid
