Evaluation of the All Right? Campaign for tangata whaiora/mental health service users in Canterbury, New Zealand.

All Right? is a wellbeing campaign developed in response to the devastating Canterbury earthquakes of 2010 and 2011. Vulnerable groups post-disaster include people with a prior history of or unresolved mental illness. This research focussed on the reach and impact of All Right? specifically for tangata whaiora/mental health service users.

Liquid chromatography/chemical reaction interface mass spectrometry as an alternative to radioisotopes for quantitative drug metabolism studies.

Chemical reaction interface mass spectrometry (CRIMS) was coupled on-line with HPLC using a Vestec particle beam interface. A helium-assisted nebulizer provided added stability with no loss in accuracy or precision as compared to the thermospray nebulizer at flow rates of up to 1.0 mL/min using isocratic conditions.

Characterization of hydroxyeicosatetraenoic acids and hydroxyeicosatetraenoic acid phosphatidylcholines by liquid secondary ion tandem mass spectrometry.

Arachidonic acid is oxidized to regioisomeric 5(S)-, 12(S)- and 15(S)-hydroxyeicosatetraenoic acids by the corresponding 5-, 12- and 15-lipoxygenases. These hydroxylated fatty acids can then be incorporated into cellular phospholipids. Negative liquid secondary ion tandem mass spectrometry using a high-energy collision regime in a tandem four-sector mass spectrometer was used to characterize regioisomeric hydroxyeicosatetraenoic acids and the corresponding hydroxyeicosatetraenoic phosphatidylcholine species.
