To estimate the relative frequency of mismatch repair genes, rearrangements in hereditary nonpolyposis colorectal cancer (HNPCC) families without detectable mutations in MSH2 or MLH1, we have analyzed by multiplex PCR of short fluorescent fragments MSH2, MLH1, and MSH6 in 61 families, either fulfilling Amsterdam criteria or including cases of multiple(More)
Fucoïdans are a family of high molecular weight sulphated polysaccharides in the Mr range 8 x 10(5) -10(6), widely dispersed in brown seaweed cell wall. When extracted from several brown algae, they exhibit anticoagulant properties. The chemical degradation of a crude extract, from Pelvetia canaliculata, was undertaken to obtain a low molecular weight(More)
The adsorption of albumin and thrombin to insoluble modified polystyrene resins bearing sulphonate (PSSO3) and L-arginyl methyl ester groups (PAOM) was investigated in both purified and plasma systems. Radioiodinated proteins were used to follow adsorption in a 'minicolumn' experiment. Albumin adsorption was found to follow the Langmuir model and specific(More)
Antithrombin III (AT III) inhibits thrombin via an arginine-serine interaction. Insoluble polystyrene resins grafted with arginyl methyl ester have been synthesized, and their interaction with thrombin tested. One of these resins was selected for its high affinity for thrombin. In this paper we report the characteristics of this thrombin resin interaction.(More)
