Blubber samples from harbour (Phoca vitulina) and grey seals (Halichoerus grypus) captured in the St Lawrence Estuary were analysed for PCBs and OC pesticides. Concentrations of sigma PCB, sigma DDT, sigma CHLOR and mirex were higher in harbour than in grey seals, while sigma HCH and HCB were similar in the two species. Age vs. concentration plots showed(More)
AIMS The urokinase-type plasminogen activator receptor (uPAR) is a key molecule for pericellular proteolysis in tumour cell invasion and metastasis. The aim was to evaluate the prognostic impact of uPAR in invasive breast cancer dependent on which cell types within the tumour express uPAR. METHODS AND RESULTS uPAR expression was analysed by(More)
Levels of tris (4-chlorophenyl) methanol (TCPM) and its presumed precursor tris (4-chlorophenyl) methane (TCPMe) are reported in marine mammals from the Estuary and Gulf of St. Lawrence, Canada. These compounds were measured in blubber samples of seals and whales using ion trap mass spectrometry (MS/MS) detection. Detectable concentrations of both TCPM and(More)
