Understanding how the brain extracts the behavioral meaning carried by specific vocalization types that can be emitted by various vocalizers and in different conditions is a central question in auditory research. This semantic categorization is a fundamental process required for acoustic communication and presupposes discriminative and invariance properties of the auditory system for conspecifi...

Background: Antimitotic drugs represent some of the most popular vascular disrupting agents used today in the fight against cancer. Colchicine is the first known antimitotic alkaloid. The drug binds to tubulin proteins and depolymerizes microtubules. Despite the impressive therapeutic activity as an antimitotic agent, colchicine is fatally toxic when administered to cancer patients intravenousl...

Bicarbonate secretion in the intestine (duodenum) of marine fish has been suggested to play a major role in the regulation of calcium availability for uptake. However, while the end process may lead to carbonate precipitation, the regulation of transport of calcium and/or bicarbonate may actually result in the fine-tuning of calcium availability for transport. To test this hypothesis sea bream ...
