UNLABELLED BACKGROUND The therapeutic activities of Andrographis paniculata are attributed to four major active diterpenoids: andrographolide (AP1), 14-deoxy-11,12-didehydroandrographolide (AP3), neoandrographolide (AP4), and 14-deoxyandrographolide (AP6). This study aims to quantify the four active diterpenoids in various plant organs of A. paniculata at different growth stages in greenhous...

This case study provides an in-depth analysis of Siemens' lessons learned when implementing knowledge management. For the analysis of the case-study data, we use established tools from the marketing literature, and integrate these with the change management literature. The aim is to provide a rich-yet-parsimonious conceptualisation of Siemens' lessons learned in dealing with two distinct implem...

Pasco et al (pp. 322–326) investigated the role of tobacco smoking as a risk factor for major depressive disorder, using data from an Australian population-based sample of women. They found both cross-sectional and longitudinal evidence for an association between smoking and depression, particularly among heavy smokers. Using a range of brain imaging techniques, de Win et al (pp. 289–296) found...
