A synchronous measurement system includes a main controller, a plurality of sub-controllers connected to the main controller, and a plurality of sensor units connected to the sub-controller. The at least one ventilation opening is provided within a housing that at least partially accommodates the support structure and the covering in the stowage position. The modulated data is applied to a liquid crystal panel at the initial period of one frame period. Diagnostic methods utilizing compositions of the invention are also provided. In particular, 15-epi-lipoxins and their use in ameliorating undesired cell proliferation, which characterizes diseases such as cancer, are also disclosed.
