To evaluate the effect of environmental change in captivity, the affiliative (contact/proximity and allogrooming) and individual (approach, leaving, scent mark, locomotion, and autogrooming) behavior of five family groups of common marmosets, Callithrix jacchus, were recorded on weekdays (non-quiet) and at the weekend (quiet) for two months. In addition, fecal samples were collected for four of these groups to measure their cortisol levels under both conditions. The behavioral pattern and hormonal profile of breeding pairs and their offspring were modified by different management routines used in the experimental conditions. We found that the animals spent more time in affiliative interactions at the weekend, whereas on weekdays, they showed more individual behaviors. Moreover, cortisol levels of breeding pairs and their offspring were higher on weekdays, suggesting that common marmosets living in captivity react to environmental modification by changing their behavioral and hormonal pattern.Artigo Effect of sildenafil in renal ischemia/reperfusion injury in rats(2010) Medeiros, Paulo José de; Neto, Arthur Villarim; Lima, Francisco Pignataro; Azevedo, Ítalo Medeiros; Leão, Layra Ribeiro de Sousa; Medeiros, Aldo CunhaArtigo Daily anticipatory rhythms of behavior and body temperature in response to glucose availability in rats(2012) Carneiro, Breno T. S.; Fernandes, Diego A. C.; Medeiros, Caio F. P.; Diniz, Nathália L.; Araujo, John FonteneleWhen food is available recurrently at a particular time of day, several species increase their locomotion in the hours that precede food delivery, a phenomenon called food anticipatory activity (FAA). In mammals, many studies have shown that FAA is driven by a food-entrained circadian oscillator (FEO) that is distinct from the light-entrained pacemaker in the suprachiasmatic nucleus of the hypothalamus. Few studies have investigated the effect of sugar ingestion on food anticipatory rhythms and the FEO. We aimed to extend the understanding of the role of glucose on the emergence of food anticipatory rhythms by investigating whether glucose ingestion is sufficient to produce daily food anticipation, reflected by motor activity and core body temperature rhythms. Under a 12 h/12 h light/dark cycle, chow-deprived rats had glucose solution available between Zeitgeber Time (ZT) 6 and ZT 9 for 10 days (glucose restriction group), whereas control animals had chow available within the same time window (chow restriction group). Animals in both groups exhibited anticipatory motor activity and body temperature around the fourth day of the scheduled food restriction. Glucose-fed rats ingested ~15 kcal on the days immediately before FAA emergence and reached an intake of ~20 kcal/day, whereas chow-fed rats ingested ~40 kcal/day. The glucose restriction group exhibited a pattern of food anticipation (activity and temperature) that was extremely similar to that observed in the chow restriction group. We conclude that glucose ingestion is a sufficient temporal cue to produce recurrent food anticipation, reflected by activity and temperature rhythms, in rats.Artigo Food entrainment: major and recent findings(2012-11) Carneiro, Breno T. S.; Araujo, John F.Mammals exhibit daily anticipatory activity to cycles of food availability. Studies on such food anticipatory activity (FAA) have been conducted mainly in nocturnal rodents. They have identified FAA as the behavioral output of a food entrained oscillator (FEO), separate of the known light entrained oscillator (LEO) located in the suprachiasmatic nucleus (SCN) of hypothalamus. Here we briefly review the main characteristics of FAA. Also, we present results on four topics of food anticipation: (1) possible input signals to FEO, (2) FEO substrate, (3) the importance of canonical clock genes for FAA, and (4) potential practical applications of scheduled feeding. This mini review is intended to introduce the subject of food entrainment to those unfamiliar with it but also present them with relevant new findings on the issue.Artigo Caminos de la neurociencia en América Latina(2013-01) Cardenas, Fernando P.; Araujo, John Fontenele; León, Laura AndreaNão possui resumo.Artigo Dream characteristics in a Brazilian sample: an online survey focusing on lucid dreaming(2013-12) Rolim, Sérgio A. Mota; Targino, Zé H.; Souza, Bryan C.; Blanco, Wilfredo; Araujo, John F.; Ribeiro, SidartaDuring sleep, humans experience the offline images and sensations that we call dreams, which are typically emotional and lacking in rational judgment of their bizarreness. However, during lucid dreaming (LD), subjects know that they are dreaming, and may control oneiric content. Dreaming and LD features have been studied in North Americans, Europeans and Asians, but not among Brazilians, the largest population in Latin America. Here we investigated dreams and LD characteristics in a Brazilian sample (n = 3,427; median age = 25 years) through an online survey. The subjects reported recalling dreams at least once a week (76%), and that dreams typically depicted actions (93%), known people (92%), sounds/voices (78%), and colored images (76%). The oneiric content was associated with plans for the upcoming days (37%), memories of the previous day (13%), or unrelated to the dreamer (30%). Nightmares usually depicted anxiety/fear (65%), being stalked (48%), or other unpleasant sensations (47%). These data corroborate Freudian notion of day residue in dreams, and suggest that dreams and nightmares are simulations of life situations that are related to our psychobiological integrity. Regarding LD, we observed that 77% of the subjects experienced LD at least once in life (44% up to 10 episodes ever), and for 48% LD subjectively lasted less than 1 min. LD frequency correlated weakly with dream recall frequency (r = 0.20, p < 0.01), and LD control was rare (29%). LD occurrence was facilitated when subjects did not need to wake up early (38%), a situation that increases rapid eye movement sleep (REMS) duration, or when subjects were under stress (30%), which increases REMS transitions into waking. These results indicate that LD is relatively ubiquitous but rare, unstable, difficult to control, and facilitated by increases in REMS duration and transitions to wake state. Together with LD incidence in USA, Europe and Asia, our data from Latin America strengthen the notion that LD is a general phenomenon of the human species.
