The Role of Repetitive Negative Thoughts in the Vulnerability for Emotional Problems in Non-Clinical Children.

The current study examined the role of repetitive negative thoughts in the vulnerability for emotional problems in non-clinical children aged 8-13 years (N = 158). Children completed self-report questionnaires for assessing (1) neuroticism and behavioral inhibition as indicators of general vulnerability (2) worry and rumination which are two important manifestations of repetitive negative thoughts, and (3) emotional problems (i.e.

Development of an integrated chromatographic system for on-line digestion and characterization of phosphorylated proteins.

The development of an integrated chromatographic system for complete phosphoprotein analysis is described. The digestion of phosphoproteins with trypsin- or pronase-based monolithic bioreactors is carried out on-line with selective enrichment on a TiO(2) trap and separation of the produced phosphopeptides by reversed-phase liquid chromatography-multiple mass spectrometry (RPLC/MS(n)). A detailed study on the selective extraction of peptides with different degrees of phosphorylation on TiO(2) cartridges is discussed.
