13. Tratamento interdisciplinar em adolescentes obesos com esteatose hepatica não alcoolica: papel dos neuropeptideos e adipocinas pro e anti-inflamatorias / Interdisciplinary treatment in obese adolescents with NAFLD: role of neuropeptides and adipokines pro and anti-inflammatory
Introdução: A complexidade da fisiopatologia na Esteatose Hepática Não Alcóolica (EHNA) envolve uma interface entre as adipocinas e a regulação neuroendócrina do balanço energético, incluindo o papel do sistema Neuropeptídeo Y/Proteína agouti relacionada. Objetivo: estabelecer a relação entre a razão NeuropeptídeoY/Proteína relacionada Agout

14. Effects of oral administration of S-nitrosothiols and knectic evaluation of the kinetic propensity and resistance to diet induced obessity / Efeitos da administração orogástrica de s-nitrosotióis e avaliação cinética da propensão e resistência à obsidade induzida por dieta
In the present study, the nitric oxide (NO)-associated physiological actions obtained topically on the gastric mucosa and systemically in oral administrations of two NO donors-S-nitrosothiols (RSNOs), S-nitrosoglutathione (GSNO) and S-nitroso-N-acetylcysteine (SNAC) were investigated in animal models. The topical ex vivo administration of RSNOs solutions on

15. Participação do sistema da orexina na sensibilização comportamental ao efeito estimulante do etanol em camundongos machos / Role of orexin system in ethanol-induced behavioral sensitization in male mice
Orexins are two neuropeptides, orexin-A and orexin-B, derived from the same precursor gene (pre-pro-orexin) produced by a few thousand neurons located in the perifornical area of the lateral hypothalamus. Despite having a restricted production, orexinergic neurons project widely to brain structures that regulate a number of endocrine and homeostatic function

16. Estradiol-induced hypophagia is associated with the differential mRNA expression of hypothalamic neuropeptides
Estradiol participates in the control of energy homeostasis, as demonstrated by an increase in food intake and in body weight gain after ovariectomy in rats. In the present study, female Wistar rats (200-230 g, N = 5-15 per group), with free access to chow, were individually housed in metabolic cages. We investigated food intake, body weight, plasma leptin l

17. Central actions of glucocorticoids in the control of body fluid homeostasis: Review
The involvement of the hypothalamic-pituitary-adrenal axis in the control of body fluid homeostasis has been extensively investigated in the past few years. In the present study, we reviewed the recent results obtained using different approaches to investigate the effects of glucocorticoids on the mechanisms of oxytocin and vasopressin synthesis and secretio

18. Melanin-concentrating hormone and orexin A neuropeptidergic systems in the dorsal motor nucleus of the vagus nerve in rat / Sistema neuropeptidergico do hormonio concentrador de melanina e da orexina A no nucleo motor dorsal do nervo vago em rato
Melanin-concentrating hormone (MCH) and orexin-A (OXA) are neuromediators expressed in neurons distributed in the diencephalum, mainly in the lateral hypothalamic area, projecting nerve fibers to several parts of the central nervous system. These neuropeptides exert potent orexigenic activity, increasing feeding and controlling the energetic balance. Consequ

19. Estudo neuroquímico do núcleo pré-mamilar ventral nos animais submissos durante os encontros agonísticos sociais. / Neurochemic study of the premammillary ventralis nucleus on submissive animals during social agonistic encounters.
Aggressive behavior occurs when the interests of one or more individuals conflict. Territory is one of these interests, and the resident intruder paradigm is widely used to observe the expression of social agonistic behaviors. The dominance behavior has been studied under several views and it was shown that it can be raised by the presence of the female, its

20. Efeitos do estresse pré-natal sobre a atividade de linfócitos de uma prole de camundongos / Effects of prenatal stress on the lymphocytes mice litter activity
As a consequence of his fast development, the fetus is vulnerable to modifications from the hormonal maternal millieu. This is explained mainly by the permeability of the placentary barrier to several hormones and substances. Specifically, it is known that the maternal exposition to a stressor activates neuroendocrine systems (exponents, the hypothalamus-pit

21. Consequências dos tratamentos realizados com celecoxibe, -tocoferol ou losartan sobre a reatividade em carótidas de ratos submetidos à lesão com cateter balão / Consequences of the treatments performed with celecoxib, -tocopherol or losartan on the carotid of reactivity in rats subjected to injury with balloon catheter.
The injury by balloon catheter is a procedure commonly used to study the mechanisms of restenosis. The mechanical stress produced by the passage of the balloon promotes changes both in the injured artery in the contralateral artery. There was an increased density of neurons containing neuropeptides such as substance P (SP) and the Gene Related Peptide of Cal

22. Pharmacological caracterization of hemopressin and C fibres in antigen-induced arthritits in rats. / Caracterização farmacológica do papel da hemopressina e das fibras C no modelo de artrite induzida por antígeno em ratos.
Arthritis and other rheumatic conditions are among the most prevalent diseases worldwide and the most frequent cause of disability. There are many treatment options, but an effective treatment has not been established. Our aims were to investigate a possible anti-inflammatory effect of hemopressin and neuropeptide depletion on Met-BSA induced arthritis (AIA)

23. Expressão de neuromediadores e sua correlação com o padrão fenotípico e funcional do infiltrado inflamatório de lesões de leishmaniose tegumentar americana causadas por Leishmania (Viannia) braziliensis / Expression of neuromediators and its correlation with the phenotypic and functional standard of the inflammatory infiltrated one of injuries of american tegumentary leishmaniasis caused for Leishmania (Viannia) braziliensis
American Tegumentary Leishmaniasis (ATL) is an important disease in Latin America and in Brazil, represents a serious public health problem. Localized cutaneous leishmaniasis (LCL) caused by Leishmania (Viannia) braziliensis tends to be, unlike mucosal forms (LM), susceptible to specific therapy and spontaneous healing occurs in a period of six to 12 months.

24. Mutation screening in the VHL, SDHB and SDHD genes in patients with sporadic pheochromocytoma and/or paraganglioma / Rastreamento de mutações nos genes VHL, SDHB e SDHD em pacientes portadores de feocromocitoma ou também, paraganglioma esporádico
Pheochromocytomas are neuroendocrine tumors composed of chromaffin cells that produce and secrete catecholamines as well as a variety of neuropeptides, whose most common clinical manifestation is arterial hypertension. Twelve to 24% of the apparently sporadic pheochromocytomas, present germline mutations in genes previously associated to inherited familiar s
