A Better Way To 'Spell Check' Gene Sequences
A PhD student from CSIRO and the University of Queensland has found a better way to 'spell check' gene sequences and help biologists better understand the natural world. The student, Lauren Bragg, has contributed to the May issue of the prestigious journal Nature Methods highlighting her new approach and its software implementation called Acacia. Acacia analyses the output of next-generation gene sequencing instruments which read the four-letter alphabet of As, Cs, Ts and Gs - the 'bases' that code for DNA and spell out the genes of different living organisms...

Antidepressant-like activity of S 20098 (agomelatine) in the forced swimming test in rodents: involvement of melatonin and serotonin receptors.
CONCLUSION: These results demonstrate the antidepressant-like activity of repeated administration of S 20098 in the FST. Moreover, the combination of 5-HT agonists and antagonists leads to more powerful effects with S 20098 than with melatonin, thereby emphasizing the contribution of 5-HT receptors to the antidepressant activity of S 20098. Compared with imipramine and fluoxetine, the 5-HT receptor subtypes that may be involved in the antidepressant-like activity of S 20098 are not similar. Indeed, when considering the binding properties of S 20098, the 5-HT(2C) receptor subtype appears to be the most attractive candidate. It is concluded that the antidepressant-like activity of S 20098 in this model most probably involves a combination of both its melatonin agonist and 5-HT(2C )receptor a...
