Analysis of a reverse transcription loop-mediated isothermal amplification (RT-LAMP) for yellow fever diagnostic
(Elsevier, 2015)Yellow Fever virus (YFV) is an important human pathogen in tropical areas of Africa and South America. Although an efficient vaccine is available and has been used since the early 1940s, sylvatic YFV transmission still ... -
Analysis of kojic acid derivatives as competitive inhibitors of tyrosinase: a molecular modeling approach
(MDPI, 2021)Abstract: Tyrosinases belong to the functional copper-containing proteins family, and their structure contains two copper atoms, in the active site, which are coordinated by three histidine residues. The biosynthesis of ... -
Anti-dengue virus activity of scytovirin and evaluation of point mutation effects by molecular dynamics and binding free energy calculations
(Elsevier, 2017)The absence of a specific treatment against DENV has led to intensive research into developing strategies for curing the infection. One lectin with high antiviral activity is scytovirin, which was isolated from the ... -
Barrita Virus, a novel virus of the patois serogroup (Genus Orthobunyavirus; Family Peribunyaviridae)
(American Society of Tropical Medicine and Hygiene, 2020)During ecological investigations for arboviruses conducted in coastal Chiapas, Mexico, in 2007, isolate MP1078 was obtained from a pool of Psorophora varipes mosquitoes. Based on antigenic characterization, this isolate ... -
Changuinola virus serogroup, new genomes within the genus Orbivirus (Family Reoviridae) isolated in the Brazilian Amazon Region

Characterization of mitochondrial genome of Haemagogus janthinomys (Diptera: Culicidae)
(Taylor & Francis, 2017)Haemagogus janthinomys is a mosquito of high importance in public health due its involvement on natural wild cycles of two important arboviruses in the Brazilian Amazon region: Yellow Fever virus (Flaviviridae, Flavivirus) ... -
Characterization of the Gamboa Virus serogroup (Orthobunyavirus Genus, Peribunyaviridae Family)
(American Society of Tropical Medicine and Hygiene, 2018)Comprehensive comparative phylogenetic analyses were performed on 17 Gamboa serogroup viruses (GAMSVs) from distinct geographic regions in the Americas and other representative members of the genus Orthobunyavirus ... -
Characterization of three novel viruses from the families nyamiviridae, orthomyxoviridae, and peribunyaviridae, isolated from dead birds collected during west nile virus surveillance in Harris County, Texas
