Objective Trans -Chalcone (TC) is an anti-inflammatory flavonoid that reduces hyperalgesia by targeting nuclear factor κB and inflammasome in gout arthritis model. However, a direct modulation of nociceptors by TC has never been investigated, which was the aim of the present study. Methods Experimental models of overt pain-like behaviors were applied as the stimuli-induced behavior depends, at least in part, on nociceptive neu...

The divergence‐with‐gene‐flow model of speciation has a strong theoretical basis with a growing number of plausible examples in nature, but remains hotly debated. Darwin’s finches of the Galápagos Archipelago have played an important role in our understanding of speciation processes. Recent studies suggest that this group may also provide insights into speciation via divergence with gene flow. On the island of Santa Cruz, rece...

Telomeres are the protective caps at the ends of all eukaryotic chromosomes. Because DNA replication of chromosome ends is incomplete, telomeres undergo sequence loss with each cell division resulting in the progressive shortening of their lengths. Telomere shortening with age is known from terrestrial mammals. We test whether this pattern is shared by marine mammals, by comparing telomere lengths between age classes in a pinn...
