    Abstract: A polymer hydrogel having a polymer formed by the crosslinking reaction of a polymeric unit A according to formula (I), with a crosslinking unit B according to formula (II) and water, wherein n=100-10,000, preferable 250-2500, more preferable 500-1500; m=independently 2-10, preferably 3 or 4; FG is a functional moiety that can be covalently coupled to the complementary functional moiety F1 or F2 of the crosslinking unit (B); k=0.01-0.05; h=0, 1 or 2; the spacer is an organic moiety, having a main chain comprising at least two functional moieties F1 and F2, wherein the length of the crosslinker in the extended conformation as determined by molecular modeling (including spacer and functional groups F1 and F2) is between 2.5 and 12 nm, or wherein the length is between 20 and 80 atoms.

    Abstract: Described herein are method, compositions and kits for prognosis of prostate cancer. The methods include determining the ratio of PCA3 and of a prostate-specific marker expression in a urine sample and correlating the value of the PCA3/prostate-specific marker ratio with the aggressiveness and mortality risk of prostate cancer in the subject. The method for prognosing prostate cancer in a sample of a patient includes assessing the amount of a prostate cancer specific PCA3 mRNA and the amount of prostate-specific marker in the sample; determining a ratio value of this amount of prostate cancer specific PCA3 mRNA over the amount of prostate-specific marker; comparing the ratio value to at least one predetermined cut-off value, wherein a ratio value above the predetermined cut-off value is indicative of a higher risk of mortality of prostate cancer as compared to a ratio value below the predetermined cut-off value.

    Abstract: The present invention relates to a method for in vitro determining generation of a haemostasis factor such as thrombin and/or plasmin in a test sample using a chemiluminescent substrate specific for said blood clotting factor. Upon cleavage of the substrate, a luminescent signal is generated with the aid of a luciferase. The invention also relates to a kit for in vitro determining generation of a haemostasis factor in a test sample, and to novel chemiluminescent substrates for the determination of thrombin and plasmin.
