    Although much information on the endocrine activity of bisphenol A (BPA) is available, a proper human hazard assessment of analogues that are believed to have a less harmful toxicity profile is lacking. Here the possible effects of BPA, bisphenol F (BPF), bisphenol S (BPS), as well as the brominated structural analogue and widely used flame retardant tetrabromobisphenol A (TBBPA) on human glucocorticoid and androgen receptor (GR and AR) activation were assessed. BPA, BPF, and TBBPA showed clear GR and AR antagonism with IC50 values of 67 µM, 60 µM, and 22 nM for GR, and 39 µM, 20 µM, and 982 nM for AR, respectively, whereas BPS did not affect receptor activity. In addition, murine MA-10 Leydig cells exposed to the bisphenol analogues were assessed for changes in secreted steroid hormone levels. Testicular steroidogenesis was altered by all bisphenol analogues tested. TBBPA effects were more directed towards the male end products and induced testosterone synthesis, while BPF and BPS predominantly increased the levels of progestagens that are formed in the beginning of the steroidogenic pathway. The MA-10 Leydig cell assay shows added value over the widely used H295R steroidogenesis assay because of its fetal-like characteristics and specificity for the physiologically more relevant testicular ¿4 steroidogenic pathway. Therefore, adding an in vitro assay covering fetal testicular steroidogenesis, such as the MA-10 cell line, to the panel of tests used to screen potential endocrine disruptors, is highly recommendable.
    Dure grondbehandeling tegen wortellesieaaltjes snel terugverdiend
    Os, G.J. van; Bent, J. van der; Breeuwsma, S.J. ; Boer, M. de; Roelofs, P.F.M.M. - \ 2014
    Lisse : Praktijkonderzoek Plant & Omgeving BBF
    Toepassing van maatregelen zoals biologische grondontsmetting en de teelt van Tagetes kunnen effectief het wortellesieaaltje bestrijden, maar zijn relatief duur in vergelijking met de toepassing van bijvoorbeeld chemische grondontsmetting. Er is een quick-and-dirty berekening gemaakt op basis van de resultaten van het project Bevordering bodemgezondheid in de sierteelt op duinzandgrond. Hieruit bleek dat de kosten binnen twee jaar waren terugverdiend.
