Many wildlife species forage on sewage-contaminated food, for example, at wastewater treatment plants and on fields fertilized with sewage sludge. The resultant exposure to human pharmaceuticals remains poorly studied for terrestrial species. On the basis of predicted exposure levels in the wild, we administered the common antidepressant fluoxetine (FLUOX) or control treatment via prey to wild-...

BACKGROUND Rat CYP2C11 (besides CYP2C6) can be regarded as a functional counterpart of human CYP2C9. The aim of the present study was to investigate the influence of classic and novel antidepressant drugs on the activity of CYP2C11, measured as a rate of testosterone 2α and 16α-hydroxylation. METHODS The reaction was studied in control liver microsomes in the presence of antidepressants, as w...

In two inbred strains of mice, C57BL/6 and 129Sv, the majority of forebrain neocortical pre-mRNA encoding the serotonin 2C (5-HT2C) receptor is altered by adenosine-to-inosine editing. As a result, >60% of all mRNAs encode receptors with reduced constitutive and agonist-stimulated activity. However, in the BALB/c strain, a genetically distinct inbred strain with lower forebrain serotonin levels...

Objective This study aimed to assess the effects of fluoxetine, a selective serotonin reuptake inhibitor, on the formation of the periodontal ligament during pregnancy and lactation in rat pups. Material and Methods Twelve pregnant rats of Wistar lineage were divided into four study groups. In the control group, 0.9% sodium chloride solution was administered orally, throughout the entire peri...

The synaptogenic hypothesis of major depressive disorder implies that preventing the onset depressive-like behavior also prevents loss hippocampal spine synapses. By applying psychoactive drugs, diazepam and fluoxetine, we investigated whether blocking development helpless by promoting stress resilience in rat learned helplessness paradigm is associated with a synaptoprotective action hippocamp...
