Anti-Inflammatory and antioxidant properties of black mulberry (Morus nigra L.)...
Lúcio, Karine de Pádua; Rabelo, Ana Carolina Silveira; Araújo, Carolina Morais; Brandão, Geraldo Célio; Souza, Gustavo Henrique Bianco deSepsis is a complex disease and is the cause of many deaths worldwide. Sepsis pathogenesis involves a dysregulated inflammatory response with consequent production of inflammatory mediators and reactive species. The production and excessive release of these substances into the systemic circulation trigger various cellular and metabolic alterations that are observed during the disease evolution. Thus, more studi...
Preparation and characterization of a quercetin-tetraethyl ether-based photopro...
Gonçalves, Marlucy da Cruz; Santos, Viviane Martins Rebello dos; Taylor, Jason Guy; Perasoli, Fernanda Barçante; Santos, Orlando David Henrique dosAlthough Quercetin absorbs in the UVA/UVB electromagnetic region, it is limited for applications as a UV filter due to its low lipophilicity and capacity to penetrate the epidermis. In order to overcome this limitation, we synthetized and evaluated the photo protective properties of a derivative obtained from Quercetin. The derivative was prepared by alkylation of Quercetin with iodoethane and characterized by ...
Aqueous extract of Baccharis trimera improves redox status and decreases the se...
Rabelo, Ana Carolina Silveira; Araújo, Glaucy Rodrigues de; Lúcio, Karine de Pádua; Araújo, Carolina Morais; Miranda, Pedro Henrique de AmorimThe metabolism of ethanol occurs mainly in the liver, promoting increase of reactive oxygen species and nitrogen, leading to redox imbalance. Therefore, antioxidants can be seen as an alternative to reestablish the oxidizing/reducing equilibrium. The aim of this study was to evaluate the antioxidant and hepatoprotective effect of aqueous extract of Baccharis trimera (Less.) DC., Asteraceae, in a model of hepato...

Gonçalves, Marlucy da Cruz; Taylor, Jason Guy; Rossoni Júnior, Joamyr Victor; Rabelo, Ana Carolina Silveira; Costa, Daniela Caldeira; Cazati, ThiagoA Radiação solar ultravioleta(RUV) pode induzir efeitos à pele devidos a sua ação direta ou indireta, por meio da geração de radicais livres. Esses efeitos podem provocar diversas lesões na pele humana como o câncer de pele. Como medida de proteção da pele contra os efeitos da radiação solar pode-se citar o uso de protetores solares, produtos tópicos adicionados de filtros solares UV sintéticos com propriedades...
Baccharis trimera (Carqueja) Improves metabolic and redox status in an experime...
Kaut, Natália Nogueira do Nascimento; Rabelo, Ana Carolina Silveira; Araújo, Glaucy Rodrigues de; Taylor, Jason Guy; Silva, Marcelo EustáquioDiabetes mellitus is a metabolic disorder that causes severe complications due to the increased oxidative stress induced by disease. Many plants are popularly used in the treatment of diabetes, e.g., Baccharis trimera (carqueja). The aim of this study was to explore the potential application of the B. trimera hydroethanolic extract in preventing redox stress induced by diabetes and its hypoglycemic properties. ...
Araçá (Psidium cattleianum Sabine) ameliorates liver damage and reduces hepatic...
Paulino, Alice Helena de Souza; Viana, Ana Maria Fernandes; Bonomo, Larissa de Freitas; Guerra, Joyce Ferreira da Costa; Lopes, Juliana Márcia MacedoBioactive compounds, present in some foods, act enhancing the endogenous antioxidant system and are proposed as an effective strategy in preventing the changes induced by free radicals in some diseases, such as nonalcoholic fatty liver disease (NAFLD). There has been an increase in the number of studies carried out with the aim of finding natural antioxidant compounds present in fruits, mainly the native fruits...
Recovering lead from cupel waste generated in gold analysis by Pb-Fire assay
Cerceau, Cristiane Isaac; Carvalho, Cornélio de Freitas; Rabelo, Ana Carolina Silveira; Santos, Cláudio Gouvea dos; Gonçalves, Sabrina Mayra DiasBecause of its precision and accuracy, Pb-Fire assay is the most employed method for gold analysis in geological materials. At the second stage of the method, namely cupellation, lead is oxidized to PbO which is absorbed by the cupel, leading to metallic gold as a tiny bend at the bottom of the recipient. After cupellation, cupel becomes highly contaminated with lead, making its disposal a serious risk of envir...

Baccharis trimera protege contra a hepatotoxicidade induzida pelo etanol em cél...
Rabelo, Ana Carolina SilveiraPrograma de Pós-Graduação em Ciências Biológicas. Núcleo de Pesquisas em Ciências Biológicas, Pró-Reitoria de Pesquisa de Pós Graduação, Universidade Federal de Ouro Preto.; O etanol é o álcool mais utilizado nas bebidas alcóolicas e sua metabolização ocorre principalmente no fígado, sendo seu consumo abusivo associado à hepatotoxicidade. Um dos principais mecanismos responsáveis pela hepatotoxicidade induzida ...
