Thirty-six West African Dwarf (WAD) goats were used to assess the effects of an experimental Trypanosoma congolense infection on their reproductive system. Estrous cycles were synchronised and when confirmed pregnant (n = 31), the does were randomly allocated into control and trypanosome-infected groups. After infection, the animals were carefully observed till parturition. Trypanosome infection caused an increase of rectal temperature, a significant drop in PCV (infected: 23.3 +/- 0.3%; control: 28.5 +/- 0.4%; P < 0.0001) and abortions in 27.8% of the infected does. Kids born from infected does had a lower birth weight than kids born from control goats (0.9 +/- 0.1 kg versus 1.6 +/- 0.1 kg; P < 0.0001). Eight out of 13 kids (61.5%) that were born alive from infected does died during their first week of life. Plasma pregnancy-associated glycoprotein (PAG) and progesterone concentrations were lower in the infected animals than in the controls. In general, PAG concentration in does which aborted dropped before abortion. Our results revealed that artificial T. congolense infection affected reproductive performance of WAD goats with abortions, premature births and perinatal losses being observed. Neither transplacental transmission of T. congolense nor histopathological lesions of the placenta could be demonstrated. [less ▲]

Knowledge on the impacts of endocrine disrupting chemicals (EDCs) on gastropods is scarce and their mechanisms of action are still poorly understood. In this study, effects of 3 androgens (tributyltin, testosterone and fenitrothion), 2 anti-androgens (cyproterone acetate and vinclozolin) and 1 estrogen (chlordecone) on growth and reproduction were investigated in the hermaphrodite gastropod Lymnaea stagnalis.

The behavioural effects of testosterone propionate (TP), 5alpha-dihydrotestosterone (DHT) and oestradiol benzoate (OB) were investigated in day-old chicks during imprinting sessions to a duck model. TP increased the duration of peeping while inhibiting the following reaction and the twitters. DHT had more or less the same effects while OB induces the reverse behavioural changes. The behavioural effects of hormone injections agree with behavioural sex differences observed in non-injected animals: males peep more than females which on the other hand produce more twitters. This could be related to sex differences in the hormonal status of the birds at hatching, as it is known that during incubation male chick embryos have higher plasma testosterone levels than females of corresponding ages.

Numerous studies suggest a cognitive bias for threat-related material in delusional ideation. However, few studies have examined this bias using a memory task. We investigated the influence of delusion-proneness on identity and expression memory for angry and happy faces. Participants high and low in delusion-proneness were presented with happy and angry faces and were later asked to recognise the same faces displaying a neutral expression. They also had to remember what the initial expressions of the faces had been. Remember/know/guess judgments were asked for both identity and expression memory. Results showed that delusion-prone participants better recognised the identity of angry faces compared to non-delusional participants. Also, this difference between the two groups was mainly due to a greater number of remember responses in delusion-prone participants. These findings extend previous studies by showing that delusions are associated with a memory bias for threat-related stimuli. [less ▲]

Mouse peritoneal macrophages were cultivated in vitro and treated with ethidium bromide (EB) or with cis-dichloro-diammine platinum (II) (cis-Pt). EB provokes strong cytological alterations and cell degeneration; cis-Pt was not toxic under our experimental contitions. EB-DNA complex penetrates into the macrophages, is liberated from DNA in vacuoles, then diffuses into the cell and is highly cytotoxic. Cis-Pt-DNA complex also penetrates into the cells, but cis-Pt cannot be released from DNA, cis-Pt-DNA complex accumulates inside cytoplasmic vacuoles but has no cytotoxic activity. [less ▲]

In the rat, dopamine (DA) facilitates male copulatory behavior. Indirect evidence based largely on neuroanatomical data suggest that in quail DA is also implicated in the control of male reproductive behavior but there is no pharmacological evidence to support this conclusion. To test this idea, castrated testosterone (T)-treated male quail were injected with various doses of the dopaminergic agonist apomorphine (APO) in the range 1-10,000 micrograms/kg. The sexual behavior of birds was recorded starting 15 min after APO injection for a duration of 30 min. A dose-dependent inhibition of male reproductive behavior that lasted for the entire duration of the test was observed. In a second experiment, gonadectomized T-treated male Japanese quail were injected daily with APO (0, 10, or 1,000 micrograms/kg) during 8 days. Their sexual interactions with a partner were quantified either 24 h or 15 min after the last injection. No influence of the treatment on copulatory behavior was observed 24 h after the last injection, but a strong inhibition was present when the test was performed 15 min after. To research whether the inhibitory effects of APO were due to a preferential action on D2 presynaptic autoreceptors, male quail were pretreated with two different D2 antagonists (spiperone or pimozide; 0.5 or 2 mg/kg) before being injected with APO (100 micrograms or 1 mg/kg). Spiperone facilitated male sexual behavior but did not suppress the inhibitory effect of APO. No significant effect of pimozide was observed. These results support the notion that DA modulates male sexual activity in the Japanese quail. The specific role of the different dopaminergic receptor subtypes remains, however, to be elucidated.
