- Column-switching liquid chromatography followed by lowresolution ICPMS was evaluated as a tool for speciation analysis of metal-containing biomolecules. The strategy was applied on siderophores, strong iron chelators of low molecular weight (M-w < 1500). Prior to the LC-ICPMS analysis, reductive displacement of iron by gallium was performed using ascorbate as the reducing agent to increase the sensitivity. Different experimental conditions during the exchange reaction were tested using ferrichrysin and ferrichrome for evaluation. A reaction time of 30 min and a pH of 3.9 gave an exchange yield of 27 and 83% for ferrichrysin and ferrichrome, respectively. A gradient elution profile was also developed to separate gallium-chelated siderophores on a PGC column. Detection limits for standard solutions of ferrichrysin and ferrichrome in the low-nanomolar range were obtained by monitoring the gallium-69 isotope. The combined use of LC-ICPMS and LC-ESI-MS/MS was also evaluated as a tool to identify unknown metal complexes, here siderophores, in field soil solution samples.

Associations between plasma glucose and DSM-III-R cluster B personality traits in psychiatric outpatients

- Associations between personality traits, measured with the Karolinska Scales of Personality, the Impulsiveness subscale from the Impulsiveness, Venturesomeness and Empathy (IVE) Inventory, and with self-assessed personality traits and disorders (SCID-II Screen Questionnaire), and plasma insulin, glucagon and glucose, respectively, were explored in a sample of 101 psychiatric outpatients of both sexes. No relationships between the peptide hormones and personality measures were found. However, fasting glucose values, which were all essentially within the normal biological variation, were significantly related to several personality measures. For males, a low blood glucose was associated with low stable general level of functioning, with high IVE Impulsiveness, and with self-assessed histrionic and narcissistic traits. High number of self-assessed personality traits for all cluster B personality disorders was strongly associated with high IVE Impulsiveness. The results of the present study support the generalizability of earlier findings from alcoholic impulsive offenders: in males, low blood glucose is associated with an extrovert and impulsive, acting-out behavior that includes the breaking of societal norms and rules. In contrast, for females a positive relationship between fasting glucose and self-assessed histrionic personality traits was found. Because no association between global level of functioning and glucose was found in women, these personality traits may not necessarily be maladaptive, as was the case for males.
