Delivering data and formatting information includes delivering object definition files from a server to a client; generating definitions and object instantiations at a client using JavaScript or another simple browser-interpreted language, for objects relating to data modeling and presentation; and presenting data using those objects at the client, using a web browser without a separate runtime environment or application plug-in, but maintaining substantial state at the web browser regarding the data itself and the format for its presentation. Definition files are modified to provide object properties consistent with a full object-oriented language, including for example hierarchical inheritance of object properties. Code ballooning generates definitions and individual instantiations, with the effect that a very large amount of DHTML, or another markup or presentation definition language for use with the application, can be generated from relatively small aggregate size of definition files communicated from the server to the client.

A method is described for separating, retrieving and concentrating platelets from whole blood relying on aggregation of the platelets followed by filtration. This method eliminates the need of a centrifuge for separating said cells from blood. To obtain cellular concentrates of platelets, blood is mixed with compatible agents that will aggregate cells while retaining contained growth factors. The resulting aggregates can then be separated from blood by filtration. If desired, the filter-captured aggregates are subject to a brief washing cycle where they are washed clean of residual aggregating agent, plasma, and red cells. Aggregates can then be partly or wholly deaggregated and the cells retrieved. The result is a suspension of cells and small aggregates with therapeutic levels of concentrated blood cells with included growth factors that are available for delivery to a wound site. A device that accomplishes the aforementioned process is also described.
