Filed: 2005-05-19
Abstract: The present invention provides a method, an assay and a kit for providing an indication of abnormal cell function. It was surprisingly found that the change in the serum concentration in individuals was useful as a prognostic tool to predict the clinical outcome, complications and mortality following an abnormal cell function. The present inventors describes ADAM12 as a overall general marker for abnormal cell function, and the present inventor for the first time demonstrate that ADAM12 is an important indicator of fetal chromosomal disease and placenta function.  Specifically ADAM12 is a good marker for e.g. Downs's syndrome, trisomy 18, preeclampsia, Turner syndrome in both first and second trimester. The present inventors developed an enzyme-linked immunosorbent assay (ELISA) and a time-resolved immunofluorometric assay for the quantification of ADAM12 in serum. The present application demonstrates in several examples the variation of the level in fetal abnormality and/or adverse pregnancy outcomes correlated gestational age when compared to normal controls. It is an object of the invention to provide an improvement of the existing marker tests that exhibits a decreased false positive rate.

Title: Progressive downloading of timed multimedia content
Inventor: BALCISOY SELIM
IPC: G06F15/16
Filed: 2004-06-29
Abstract: In progressive downloading of multimedia content, such as SVG files, the client buffers some data for a certain time so the content can be decoded and presented in a timely manner. In order for the client to start presenting the content of a file at an appropriate time, the client has to estimate the start-up delay time correctly. The server, prior to or at the time of sending the data, provides the client information indicative of content properties, such as the size and content presentation time of some or all scenes. The information may include transmission minimum bandwidth to ensure each remaining scene will be available before its presentation time. The client estimates the start-up delay time based on the provided information.  Furthermore, the client can determine when to remove one or more files from its data buffer in order to minimize the memory usage.
