Journal ArticleDOI
Multiplex PCR assay for identification of Corynebacterium pseudotuberculosis from pure cultures and for rapid detection of this pathogen in clinical samples
Luis G.C. Pacheco,Roberta Ribas Pena,Thiago Luiz de Paula Castro,Fernanda Alves Dorella,Robson Bahia,Renato Carminati,Marcílio N. L. Frota,Sergio C. Oliveira,Roberto Meyer,Francisco Selmo Fernandes Alves,Anderson Miyoshi,Vasco Azevedo +11 more
TL;DR: The developed assay significantly improves rapid C. pseudotuberculosis detection and could supersede bacteriological culture for microbiological and epidemiological diagnosis of CLA.
Journal ArticleDOI
Anisomycin administered in the olfactory bulb and dorsal hippocampus impaired social recognition memory consolidation in different time-points
TL;DR: The results suggest the consolidation of S-LTM requires both OB and hippocampus participation, although in different time points, which may help shedding light on the specific roles of the OB and dorsal hippocampus in social recognition memory.
Journal ArticleDOI
Home-cage odors spatial cues elicit theta phase/gamma amplitude coupling between olfactory bulb and dorsal hippocampus.
Roberta Ribas Pena,Daniel de Castro Medeiros,Leonardo de Oliveira Guarnieri,Julio Boriollo Guerra,Vinícius Rezende Carvalho,Eduardo M. A. M. Mendes,Grace S. Pereira,Márcio Flávio Dutra Moraes +7 more
TL;DR: The results suggest that exploration of familiar odors in a new context involves dynamic coupling between the olfactory bulb and dorsal hippocampus, and that this coupling occurs during exploration of home-cage odors.
Journal ArticleDOI
Neurogenesis Inhibition Prevents Enriched Environment to Prolong and Strengthen Social Recognition Memory, But Not to Increase BDNF Expression.
Ana Raquel Pereira-Caixeta,Leonardo de Oliveira Guarnieri,Roberta Ribas Pena,Thomaz Lüscher Dias,Grace S. Pereira +4 more
TL;DR: It is found that EE increased BDNF expression in the HIP and OB of mice; at the same time, it allowed SRM to last longer, suggesting that newborn neurons improve SRM persistence through a BDNF-independent mechanism.
Journal ArticleDOI
Delay of neuropathic pain sensitization after application of dexamethasone-loaded implant in sciatic nerve-injured rats
Leandro F.S. Bastos,Juliana P. Vago,Thais Rolla de Caux,Bruna Lopes da Costa,Adriana M. Godin,Raquel Rezende Menezes,Roberta Ribas Pena,Armando Silva-Cunha,Lirlândia P. Sousa,Renes R. Machado,Márcio Flávio Dutra Moraes,Sílvia Ligório Fialho,Márcio M. Coelho +12 more
TL;DR: It is demonstrated that the dexamethasone-loaded biodegradable implant suppresses allodynia development and peripheral neuroinflammation and can reduce the potential side effects associated with oral anti-inflammatory drugs.
