Maternally deprived rats were treated with tianeptine (15 mg/kg) once a day for 14 days during their adult phase. Their behavior was then assessed using the forced swimming and open field tests. The BDNF, NGF and energy metabolism were assessed in the rat brain. Deprived rats increased the immobility time, but tianeptine reversed this effect and increased the swimming time; the BDNF levels were decreased in the amygdala of the deprived rats treated with saline and the BDNF levels were decreased in the nucleus accumbens within all groups; the NGF was found to have decreased in the hippocampus, amygdala and nucleus accumbens of the deprived rats; citrate synthase was increased in the hippocampus of non-deprived rats treated with tianeptine and the creatine kinase was decreased in the hippocampus and amygdala of the deprived rats; the mitochondrial complex I and II-III were inhibited, and tianeptine increased the mitochondrial complex II and IV in the hippocampus of the non-deprived rats; the succinate dehydrogenase was increased in the hippocampus of non-deprived rats treated with tianeptine. So, tianeptine showed antidepressant effects conducted on maternally deprived rats, and this can be attributed to its action on the neurochemical pathways related to depression.
Este estudo objetivou analisar a diversidade florística da comunidade de bromélias epifíticas em um fragmento florestal urbano no Parque Ecológico Municipal José Milanese no município de Criciúma, sul de Santa Catarina. A flora epifítica de Bromeliaceae foi registrada utilizando-se o método expedito por caminhamento e de quadrantes centrados. A diversidade e frequência foram estimadas pelo número de espécies e pela ocorrência (presença) em cada zona do forófito. Foram registradas as estratégias de polinização e dispersão para cada espécie observada. Para a caracterização da distribuição horizontal foram calculadas as frequências relativas por forófitos e por segmentos de forófitos. Foram registradas 18 espécies de bromeliáceas, sendo 13 espécies pelo levantamento fitossociológico e cinco pelo método de caminhamento. Entre os cinco gêneros encontrados, Tillandsia e Vriesea tiveram o maior número de espécies. A frequência e a riqueza das espécies mostraram diferenças significativas entre fuste e copa. Os valores obtidos por meio da análise de correlação demonstraram que os diâmetros maiores dos forófitos apresentaram maior riqueza de espécies. Estudos aprofundados que visem a levantar a biodiversidade e estrutura das comunidades vegetais são relevantes para propor medidas de conservação destes fragmentos florestais, que mantém grande biodiversidade local.Palavras-Chave: Biodiversidade, Bromeliaceae, estrutura comunitária, florística.
Inga Mill. belongs to mimosoid clado (Fabaceae, Caesalpinioideae) with 131 species in Brazil. It is the most expressive genus of Fabaceae. This study aimed to perform a bibliometric analysis on Inga from Santa Catarina state. A survey of the published literature was conducted using the electronic databases of the Web of Science, Scopus and Scielo, with the accepted names of Inga species and its synonyms. Papers were distributed in four subject categories: C1 (Ecological), C2 (morphology, anatomy, histology, physiology and genetics), C3 (production and use) and C4 (biochemical and nutritional properties). We registered 232 papers for 13 species of Inga, exhibiting remarkable growth over time. C1 was the most expressive subject category, mainly by nutrient supply, shading and nitrogen fixing capacity. The subjects diversifying over the years, with registered papers in all categories. Inga edulis, I. vera and I. marginata were the most registered species in our survey. We did not find papers on I. edwallii, I. sellowiana and I. vulpina. Our results showed an increase in the number of articles on Inga over time, especially in the last 13 years. However, some important gaps need to be addressed, such as the relatively small number and/or lack of studies conducted for some species.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
