Abstract: Several studies have demonstrated that nicotine (NIC) exhibits antidepressant-like effects. In addition, it has been suggested that sexual hormones participate in the antidepressant actions of antidepressives. The present study was designed to analyze the effect of orchiectomy and the supplementation of testosterone propionate (TP) or 17?-e stradiol (E2) on the antidepressant properties of NIC using the forced swimming test (FST), as well as to determine possible changes in the FST during different time periods after orchiectomy. In order to evaluate the influences of orchiectomy on the effects of NIC, the study first evaluated the effects of different time periods on orchiectomized rats (15, 21, 30, 45 and 60days) that were subjected to the FST. Then, different doses of NIC (0.2, 0.4, 0.8, 1.6mg/kg, sc) were administered for 14days to both intact and orchiectomized rats (after 21day) which were then also subjected to the FST. Finally, the influence of the TP or E2 supplementation on the antidepressant-like effect of NIC on orchiectomized rats (after 21days) was also analyzed. Results reveal that orchiectomy significantly increased immobility behavior and decreased swimming and climbing up to 60days after castration. In contrast, NIC decreased immobility behavior and increased swimming in intact rats; whereas orchiectomy suppressed this antidepressant effect of NIC. Only with E2 supplementation was it possible to restore the sensitivity of the castrated rats to NIC. These results suggest that E2 was able to facilitate the antidepressant response of NIC in orchiectomized rats.

The hatching rate observed for each of the two studied groups of eggs was 78.1% (n = 2298) on the group fed on hens and 82.1% (n = 2704) on that fed on rabbits, and the average time of hatching was 20 days. Mean time-lapse for beginning feeding was under 3 min in nymphal stages and postfeed defecation delay was under 10 min in all stages, in both cohorts. Mean feeding time was significantly (P < 0.05) shorter in triatomines fed on hens than on rabbits. A similar number of nymphs of each cohort, 69 fed on hens (34.5%) and 68 fed on rabbits (34%), completed the cycle. No significantly (P > 0.05) differences were recorded among the average times from NI to adult in the cohort fed on hens (196.8 15.8 days) and the average time in the cohort fed on rabbits (189.5 22.9). The average span in days for each stage fed on hens was not significantly different to the average span for each stage fed on rabbits. The number of blood meals at each nymphal stage varied from 1 to 6 in both cohorts. The mortality rates were higher on fifth nymphal stage, in both cohorts. No significant (P > 0.05) differences were recorded on mortality rates on most nymphal stages of both cohorts. The average number of eggs laid per female from the cohort fed on hens in a 9-month period was 791.1, whereas the average number of eggs in the cohort fed on rabbits was 928.3.",,,,,,,,,"http://hdl.handle.net/20.500.12104/42239","http://www.scopus.com/inward/record.url?eid=2-s2.0-0037928894&partnerID=40&md5=54c023b2d8bf896ecfc74c2e9ccc04d7",,,,,,"2",,"Memorias do Instituto Oswaldo Cruz",,"227

The infinite-order calculus exhibits structure not apparent when one studies only finite-order symmetries. The search for finite-order symmetries can then be reposed as one of looking for solutions of a coupled system of PDEs that are polynomial in certain parameters. Among the simple consequences of the calculus is that one can generate algorithmically a canonical basis for the space. Similarly, we can develop a calculus for conformal symmetries of the time-dependent Schrödinger equation if it admits R separation in some coordinate system. This leads to energy-shifting symmetries.
