Gentle handling temporarily increases c-Fos in the substantia nigra pars compacta

Dopaminergic neurotransmission is involved in the regulation of sleep. In particular, the nigrostriatal pathway is an important center of sleep regulation. We hypothesized that dopaminergic neurons located in substantia nigra pars compacta (SNpc) could be activated by gentle handling, a method to obtain sleep deprivation (SD). Adult male C57/BL6J mice (N = 5/group) were distributed into non-SD (NSD) or SD groups. SD animals were subjected to SD once for 1 or 3 h by gentle handling. Two experiments were performed. The first determined the activation of SNpc neurons after SD, and the second examined the same parameters after pharmacologically induced dopaminergic depletion using intraperitoneal reserpine (2 mg/kg). After 1 or 3 h, SD and NSD mice were subjected to motor evaluation using the open field test. Immediately after the behavioral test, the mice were perfused intracardially to fix the brain and for immunohistochemical analysis of c-Fos protein expression within the SNpc. The open field test indicated that SD for 1 or 3 h did not modify motor behavior. However, c-Fos protein expression was increased after 1 h of SD compared with the NSD and 3-h SD groups. These immunohistochemistry data indicate that these periods of SD are not able to produce dopaminergic supersensitivity. Nevertheless, the increased expression of c-Fos within the SNpc suggests that dopaminergic nigral activation was triggered by SD earlier than motor responsiveness. Dopamine-depleted mice (experiment 2) exhibited a similar increase of c-Fos expression compared to control animals indicating that dopamine neurons are still activated in the 1-h SD group despite the exhaustion of dopamine. This finding suggests that this range (2-5-fold) of neuronal activation may serve as a marker of SD.

A Valencior Pars no defensor pacis de Marsílio de Pádua

Marsílio de Pádua (1280-1343) foi um pensador da Idade Média que escreveu duas obras de filosofia política que influenciaram a modernidade. Este estudo analisa o termo valencior pars, da obra Defensor Pacis. Marsílio parece definir essa parte preponderante como sendo a representação do conjunto dos cidadãos que não tem uma natureza débil. Isso sugere que a valencior pars é tanto qualitativamente superior quanto uma maioria numérica dos cidadãos. O apelo a uma mistura de considerações quantitativas e qualitativas era familiar no contexto das eleições medievais da Igreja, que geralmente apoiava a parte maior e mais razoável (maior et saniors pars) das instituições eleitorais. Marsílio sugere que a valencior pars pode ser identificada com o costume honrado do governo, entretanto, parece que a mesma corresponde a qualquer parte da coletividade cuja decisão eleitoral é decisiva. Nesse sentido, o filósofo paduano está de acordo com a análise original de Aristóteles.
