Antinociceptive effects of buprenorphine in zebrafish larvae: an alternative for rodent models to study pain and nociception?
Contributor(s):: Steenbergen, P. J., Bardine, N.
The underlying processes of nociception and pain are, despite the rodent models available, still not fully understood. One of the drawbacks of rodent model systems is the difficulty to screen compound libraries for their influence on nociception, thus slowing down the discovery of novel...

The preference of 0+ and 2+ gilthead seabream Sparus aurata for coloured substrates or no-substrate
Contributor(s):: Batzina, A., Sotirakoglou, K., Karakatsouli, N.
