13. PERFIL FARMACOLÓGICO DO TIPO ANTIDEPRESSIVO DO COMPOSTO 3-(4-FLUOROFENILSELENIL)-2,5 DIFENILSELENOFENO: ENVOLVIMENTO DO SISTEMA SEROTONINÉRGICO / ANTIDEPRESSANT-LIKE PHARMACOLOGICAL PROFILE OF 3-(4- FLUOROPHENYLSELENYL)-2,5-DIPHENYLSELENOPHENE: INVOLVEMENT OF SEROTONERGIC SYSTEM
Depression is a serious, recurrent and incapacitating psychiatric condition with a heavy social burden. The pharmacological approach to this disorder employs therapy with antidepressant drugs, which have side effects and numerous limitations. In view of the promising pharmacological properties of containing-selenium molecules, this study evaluated the effect

14. InvestigaÃÃo da aÃÃo central do carvacrol em modelos de ansiedade, depressÃo e convulsÃo em camundongos e possÃveis mecanismos farmacolÃgicos envolvidos. / Investigation of central actions of carvacrol in animal models of anxiety, depression and convulsion in mice and possible pharmacological mechanisms involved.
Carvacrol (5-Isopropyl-2-methylphenol) is a monoterpenic phenol present in the essencial oil of many plants. It is the major component of the essential oil fraction of oregano and thyme. This work presents the behavioral effects of carvacrol in animal models of anxiety, depression, sedation and convulsion, such as, elevated plus maze (EPM), open field, rota

15. Serotonin and circadian rhythms
All mammal behaviors and functions exhibit synchronization with environmental rhythms. This is accomplished through an internal mechanism that generates and modulates biological rhythms. The circadian timing system, responsible for this process, is formed by connected neural structures. Pathways receive and transmit environmental cues to the central oscillat

16. Monoamines in the pedal plexus of the land snail Megalobulimus oblongus (Gastropoda, Pulmonata)
In molluscs, the number of peripheral neurons far exceeds those found in the central nervous system. Although previous studies on the morphology of the peripheral nervous system exist, details of its organization remain unknown. Moreover, the foot of the terrestrial species has been studied less than that of the aquatic species. As this knowledge is essentia

17. Administração prolongada do ácido 13-cis-retinóico (isotretinoína) em camundongos machos adolescentes: comportamentos emocionais e quantificação de transcritos de componentes do sistema serotoninérgico central. / Chronic administration of 13-cis-retinoic acid (isotretinoin) in young male mice: emotion-related behaviors and quantification of central serotonergic system transcripts.
O ácido 13-cis-retinóico (13-cis-RA, isotretinoína) é um retinóide sintético de uso oral prolongado, prescrito em altas doses, para o tratamento da acne. Age primariamente diminuindo a atividade da glândula sebácea e reduzindo a inflamação. Desde a aprovação do uso do 13-cis-RA, tem-se relatos na literatura de sintomas psiquiátricos incluindo de

18. AlteraÃÃes comportamentais e neuroquÃmicas provocadas por diferentes perÃodos de retirada apÃs tratamento subcrÃnico com cocaÃna em ratos: envolvimento dos sistemas dopaminÃrgico, serotonÃrgico e noradrenÃrgico / Behavioral and neurochemistry alterations caused by different times of withdrawal after subcronic treatment with cocaine in rats: Involvement of dopaminergic system, serotonergic and noradrenergic
A cocaÃna à uma droga consumida mundialmente e considerada hoje como um problema de saÃde pÃblica. Uma das principais dificuldades enfrentadas no combate ao vÃcio da cocaÃna, na maioria dos casos, està relacionada aos sintomas de abstinÃncia da droga, como ansiedade, depressÃo, irritabilidade, fadiga e insÃnia, fazendo com que o indivÃduo volte a

19. Tratamento neonatal com agonista 5-HT1A: repercussÃes sobre o desenvolvimento da atividade locomotora em ratos
Locomotion is an important function to living beings. Environmental changes that occur during the critical period of development can promote changes in the development of locomotor activity, bringing impairment for the individual. Works using automatic analysis of behavior are of great importance for the study of locomotion. Among the systems that can influe

20. Efeitos da administração prolongada do esteróide anabolizante decanoato de nandrolona em comportamentos emocionais e na expressão de genes relacionados ao sistema serotoninérgico em diferentes áreas cerebrais de camundongos / Effects of prolonged administration of the anabolic-androgenic steroid nandrolone decanoate in emotional behaviors and serotonergic system related genes expression in several brain areas of mice
Nandrolone decanoate is a highly abused anabolic-androgenic steroid (AAS) by individuals looking for gains in physical strength or body appearance. Supraphysiological doses of this testosterone synthetic derivative have been associated with many physical and psychiatric adverse effects, especially reported episodes of impulsiveness and overt aggressive behav

21. EVALUATION OF ANTONOCICEPTIVE ACTION OF CRUDE EXTRACT, FRACTIONS AND COMPOUNDS OBTEINED OF Geissospermum vellosii / AVALIAÇÃO DA ATIVIDADE ANTINOCICEPTIVA DO EXTRATO BRUTO, DAS FRAÇÕES E DOS COMPOSTOS OBTIDOS DE Geissospermum vellosii
The present study examined the antinociceptive effects of Geissospermum vellosii in chemical behavioral models of nociception. G. vellosii crude extract, dichloromethane fraction (1-100 mg/kg), or aspidospermine (0.001-1 mg/kg), were administered by p.o. route, 60 min earlier tests. Crude extract produced inhibition of formalin-induced inflammatory nocicepti

22. Differential response to gepirone but not to chlordiazepoxide in malnourished rats subjected to learned helplessness
The learned helplessness (LH) paradigm is characterized by learning deficits resulting from inescapable events. The aims of the present study were to determine if protein-calorie malnutrition (PCM) alters learning deficits induced by LH and if the neurochemical changes induced by malnutrition alter the reactivity to treatment with GABA-ergic and serotonergic

23. Serotonergic system - Interactions with the circadian timing system. / Sistema serotonérgico - relações com o sistema de temporização circadiano.
Componente essencial do sistema de temporização circadiano, o núcleo supraquiasmático (NSQ) possui três aferências principais: o trato retinohipotalâmico (TRH), o trato geniculohipotalâmico (TGH) e as terminações serotonérgicas da rafe. Suas células possuem oscilação circadiana autônoma que resultam na expressão rítmica dos chamados genes do

24. Suplementação com aminoácidos de cadeia ramificada (AACR): efeitos sobre o desempenho físico no calor em humanos
There are evidences that serotonin is linked to central fatigue processes and in hyperthermic stress its activity is enhanced. In order to diminish central serotonergic activation and improve performance, nutritional strategies with branched-chain amino acids (BCAA) has sought to prevent tryptophan influx to CNS, because these amino acids compete amongst the
