Hyperpolarised benchtop NMR spectroscopy for analytical applications.

Benchtop NMR spectrometers, with moderate magnetic field strengths (B=1-2.4T) and sub-ppm chemical shift resolution, are an affordable and portable alternative to standard laboratory NMR (B≥7T). However, in moving to lower magnetic field instruments, sensitivity and chemical shift resolution are significantly reduced.

Improved benchtop P NMR reaction monitoring Multi-Resonance SHARPER.

reaction monitoring of hydrogenation reactions featuring oxygen-sensitive organometallic complexes is done a P benchtop NMR spectrometer using the Multi-Resonance Sensitive Homogeneous And Resolved PEaks in Real time (MR-SHARPER) sequence. Signal enhancement generated by MR-SHARPER enables monitoring of reactivity on the order of minutes that could not be followed with traditional P{H} NMR detection.

Quantitative reaction monitoring using hydrogen-enhanced benchtop NMR spectroscopy.

The hydrogen-induced polarisation (PHIP) NMR signal enhancement technique is used to study H addition to Vaska's complex (-[IrCl(CO)(PPh)]) with both standard high-field (9.4 T) NMR and benchtop (1 T) NMR detection. Accurate and repeatable rate constants of (0.

Emotions or cognitions first? Longitudinal relations between executive functions and emotion regulation in childhood.

Executive functions and emotion regulation develop from early childhood to adolescence and are predictive of important psychosocial outcomes. However, despite the correlation between the two regulatory capacities, whether they are prospectively related in school-aged children remains unknown, and the direction of effects is uncertain. In this study, a sample drawn from two birth cohorts in Norway was biennially examined between the ages of 6 and 14 (n = 852, 50.

Association of anxiety and depression to headache, abdominal- and musculoskeletal pain in children.

The comorbidity between recurrent pain, anxiety, and depression among children is frequent and well documented. However, only a few studies of the predictive effect of anxiety and depression on pain have adjusted for symptoms of the other disorder when examining the respective relations to different pain locations, rendering the unique contribution from anxiety and depression undetermined. In the current investigation we explore the strength of associations between pain at different locations with symptoms of anxiety and depression in a community sample of 10-year-old children ( = 703).
