Research ArticleOpen accessIn the abstractAnti-Diabetic Activity of a Fraction from Cissus verticillata and Tyramine, its Main Bioactive Constituent, in Alloxan-Induced Diabetic RatsCleide de Sousa Lino, Thiago de P. Sales, Patrícia B. Gomes et al.Cissus verticillata (syn. C. sycioides, fam. Vitaceae) is a medicinal plant popularly used in Brazil, for the treatment of diabetes mellitus. The anti-diabetic activity of a fraction from leaves of Cissus verticilllata (MSF, methanol soluble fraction), as well as that of tyramine (TYR) were investigated, in the model of alloxan-induced diabetes, in male Wistar rats. The biochemical parameters studied were: … …American Journal of Pharmacology and Toxicology, Vol. 2, Issue 4 · 31 Dec 2007 · 8,627 accessesView PDFCite
Letters to the EditorOpen accessIn the abstractIs Hydroxychloroquine a Safe and Effective Choice for Covid-19 ProphylaxisRodrigo Moisés de Almeida-Leite, Tais Rondello Bonatti, Carolina Rodrigues Ponzoni et al.The authors speculate about the possibility of Hydroxychloroquine as Covid-19 Phrophylaxis in the dose of 400 mg per week. The authors compared the experience of Malaria phrophylaxis in this dose, with acceptable safety profile. Also, we compared in vitro susceptibility of SARS-Cov-2 with that of Plasmodium falciparum. This agent show significant higher potency for the first. Also, the extended Half-life … …American Journal of Infectious Diseases, Vol. 16, Issue 3 · 29 Jul 2020 · 7,048 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization of Reinforced Concrete Beams and Steel Beams: A Comparative StudyJoel M. Ozimboski, Zacarias M.C. Pravia, Moacir KripkaIn order to support the structural designer with regard to the selection of structural materials, this work presents results obtained from the optimization of reinforced concrete beams and welded “I” steel beams. To achieve this objective, both problems were formulated according to Brazilian standards, considering the cost as objective function and section dimensions as design variables. For the optimization of … …International Journal of Structural Glass and Advanced Materials Research, Vol. 4, Issue 1 · 18 Jun 2020 · 6,596 accessesView PDFCite
Research ArticleOpen accessIn the abstractExposure to Mercury at Trace Concentrations Leads to Collapse of the Hepato-Nephrocitic System in Two Neotropical Species of BumblebeeFelipe Lissoni de Andrade Nogueira, Paulo José Bálsamo, Monica Jones Costa, Fábio Camargo AbdallaThis research aimed to investigate the effects of exposure to safe concentrations of mercury on the morpho-physiology of cells of the hepato-nephrocitic system of two species of neotropical bees. Workers of the neotropical bumblebee species Bombus morio and B. atratus were exposed to 0.2 ppb mercury for 48 h by ingestion. Bioassays were performed according some direction of OECD (2017) … …American Journal of Agricultural and Biological Sciences, Vol. 14, Issue 1 · 14 Dec 2018 · 8,617 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn ADD-Oriented Software Architecture for Structuring Information to Open Government DataAndreiwid Sheffer Correa, P. L.P. Correa, F. S.C. Silva, T. CarvalhoThe huge number of heterogeneous and not standardized websites where public records are disclosed is an evidence of how unprepa¬red governments are about Open Government Data movement. This scenario is seen all over the world, especially in organizations which open data prin¬ciples are new e.g. local governments. Thus, not effective law enforcement and the lack of openness result in a … …Journal of Computer Science, Vol. 14, Issue 5 · 10 Mar 2018 · 7,633 accessesView PDFCite

Research ArticleOpen accessIn the abstractStructural Geodesic-Tchebychev Transform: An Image Similarity Measure for Face RecognitionAli Nadhim Razzaq, Zahir M. Hussain, Hind Rustum MohammedThis work presents a new holistic measure for face recognition. Face recognition involves three steps: Face Detection, Feature Extraction and Matching. In the face detection process to identify the face area in face images, Viola-Jones algorithm has been used. Feature extraction is based on performing double-transformation, where discrete Tchebychev transform is performed on the geodesic distance transform of the grayscale … …Journal of Computer Science, Vol. 12, Issue 9 · 29 Nov 2016 · 7,640 accessesView PDFCite
Research ArticleOpen accessIn the abstractHEURISTIC DISCRETIZATION METHOD FOR BAYESIAN NETWORKSMariana D.C. Lima, Silvia M. Nassar, Pedro Ivo R.B.G. Rodrigues et al.Bayesian Network (BN) is a classification technique widely used in Artificial Intelligence. Its structure is a Direct Acyclic Graph (DAG) used to model the association of categorical variables. However, in cases where the variables are numerical, a previous discretization is necessary. Discretization methods are usually based on a statistical approach using the data distribution, such as division by quartiles.
