The activation of the Akt/PKB signalling pathway in the brains of clozapine-exposed rats is linked to hyperinsulinemia and not a direct drug effect

The second generation antipsychotic drug clozapine is a much more effective therapy for schizophrenia than first generation compounds, but the reasons for this are poorly understood. We have previously shown t...

Case Study Part 1: How to Calculate Appropriate Deterministic Long-Term Toxicity to Exposure Ratios (TERs) for Birds and Mammals

In the European Union, first-tier assessment of the long-term risk to birds and mammals from pesticides is based on calculation of a deterministic long-term toxicity/exposure ratio (TER_lt). The ratio is developed...
