Plant hormones have been studied for more than a century because they have been heavily implicated in the control of plant growth and development. For many years, they have been considered to fall into five classes: auxins, cytokinins, gibberellins, abscisic acid and ethylene. More recently, a variety of additional classes such as brassinosteroids have been added and it seems likely that more w...

-A VLDL-associated cytotoxic factor was isolated from sera of pregnant rats and characterized. The inhibitory effect of this factor on the macromolecular synthesis of rat prostate adenocarcinoma cells (PA-III) was also examined. VLDL (Sf 20-4C0) was subfractionated by differential ultracentrifugal flotation and the Sf 100-400 fraction was associated with most of the oncolytic activity. Chemical...

Psychology seemed like the answer: I reasoned that understanding the mind should help one fi gure out how to change it. The problem then became the paucity of information about the mind.
