Assessment of the chemopreventive effect of casearin B, a clerodane diterpene extracted from Casearia sylvestris (Salicaceae)
(Food and Chemical Toxicology, 2013-03-01) [Artigo]
Studies have shown that Casearia sylvestris compounds protect DNA from damage both in vitro and in vivo. Complementarily, the aim of the present study was to assess the chemopreventive effect of casearin B (CASB) against ...
Microplate alamarblue assay for paracoccidioides susceptibility testing
(Journal of Clinical Microbiology, 2013-04-01) [Artigo]
CLSI method M27-A3 is not available for use with dimorphic fungi, such as those of the Paracoccidioides genus. In this study, we developed a microdilution method and added the alamarBlue reagent to test the responses of ...

(Revista de Ciências Farmacêuticas Básica e Aplicada, 2011-11-14) [Artigo]
Two biomarkers of oxidative stress were evaluated in healthy volunteers treated with daily doses of orange juice that is well known source of vitamin C and citric flavanones, which have been associated with antioxidant, ...
Brief Report: The lincRNA Hotair Is Required for Epithelial-to-Mesenchymal Transition and Stemness Maintenance of Cancer Cell Lines
(Stem Cells, 2013-12-01) [Artigo]
Hotair is a member of the recently described class of noncoding RNAs called lincRNA (large intergenic noncoding RNA). Various studies suggest that Hotair acts regulating epigenetic states by recruiting chromatin-modifying ...
Fabrication of microenvironments with different geometrical features for cell growth studies
(Journal Of Laser Micro Nanoengineering, 2014-11-01) [Artigo]
Studies of cell development in artificial microenvironments can contribute to understanding a series of physiological mechanisms that might be influenced by geometrical features of the microenvironment itself. In this work ...
Modulation of HJURP (Holliday Junction-Recognizing Protein) Levels Is Correlated with Glioblastoma Cells Survival
(PLOS ONE, 2013-04-25) [Artigo]
Background: Diffuse astrocytomas are the most common type of primary brain cancer in adults. They present a wide variation in differentiation and aggressiveness, being classified into three grades: low-grade diffuse ...
SISTEMAS QUIMILUMINESCENTES COM PEROXIDASE (EC:188.8.131.52) E SUAS APLICACOES EM ANALISES CLINICAS
(Revista de Ciencias Farmaceuticas, 1995-01-01) [Resenha]
The enzyme horseradish peroxidase HRP (EC:184.108.40.206), has both acid and basic isoenzymes, catalyses a wide range of reactions (acting as an oxiredutase or an oxidase) and is thought capable of one- or two-electrons oxidations ...

Quantitative cell-cycle protein expression in oral cancer assessed by computer-assisted system
(Histology and Histopathology, 2006-07-01) [Artigo]
The knowledge of cell-cycle control has shown that the capacity of malignant growth is acquired by the stepwise accumulation of defects in specific genes regulating cell growth. Histologic diagnosis might be improved by a ...
