AUTHORIZING PSYCHIATRIC RESEARCH: PRINCIPLES,PRACTICES AND PROBLEMS

Psychiatric research is advancing rapidly, with studies revealing new investigative tools and technologies that are aimed at improving the treatment and care of patients with psychiatric disorders. However, the ethical framework in which such research is conducted is not as well developed as we might expect. In this paper we argue that more thought needs to be given to the principles that underpin research in psychiatry and to the problems associated with putting those principles into practice. In particular, we comment on some of the difficulties posed by the twin imperatives of ensuring that we respect the autonomy and interests of the research subject and, at the same time, enable potentially beneficial psychiatric research to flourish. We do not purport to offer a blueprint for the future; we do, however, seek to advance the debate by identifying some of the key questions to which better answers are required.     

Chilling-induced Lipid Hydrolysis in the Oil Palm (Elaeis guineensis) Mesocarp

Oil palm fruits exposed to temperatures of 15 °C and belowshowed a significant increase in free fatty acid (FFA) contentin the mesocarp. This effect was most pronounced in fruits exposedto 5 °C when FFA levels exceeding 70% of the total oil wereobserved. The increase in FFA was accompanied by an increasein lipid-soluble phosphorus levels and a decrease in carotenecontent. Chilling did not have an effect on palm kernel oil.The results suggest the activation of a lipase in the mesocarpby low temperature stress. Key words: Lipase, oil palm, free fatty acid
