1. RNA editing in the chloroplast of Asian Palmyra palm (Borassus flabellifer)
Abstract We have identified 46 RNA editing sites located in 20 chloroplast (cp) genes of Borassus flabellifer (Asian Palmyra palm), family Arecaceae, and tested these genes for supporting phylogenetic study among the commelinids. Among the 46 sites, 43 sites were found to cause amino acid alterations, which were predicted to increase the hydrophobicity and t

2. An overview of the appendicular skeletal anatomy of South American titanosaurian sauropods, with definition of a newly recognized clade
Abstract: In the last two decades, the number of phylogenetically informative anatomical characters recognized in the appendicular skeleton of titanosaurian sauropod dinosaurs has increased dramatically with the discovery of new and comparatively complete specimens. Here we provide an overview of the appendicular skeletal morphology of South American titanos

3. Nota sobre o sistema de parentesco em Proto-Tupí-Guaraní
Resumo Este estudo explora o sistema de terminologia de parentesco da língua Proto-Tupí-Guaraní (PTG) a partir de uma perspectiva interdisciplinar, que soma contribuições da Etnologia, da Linguística Histórica e dos trabalhos etnográficos realizados com povos Tupí-Guaraní. Fazem-se inferências sobre pré-história cultural utilizando métodos filo

4. Molecular characterisation of the emerging measles virus from Roraima state, Brazil, 2018
Measles is a human infectious disease of global concern that is caused by the measles virus. In this study, we report the complete genome sequencing of one measles virus isolate, genotype D8, that was obtained directly from a urine sample in Boa Vista city, the capital of Roraima state in Brazil. Phylogenetic reconstruction grouped the genome described in th

5. Murine typhus in Mexico City: report of an imported case
ABSTRACT Murine typhus is endemic in several countries. We herein report an imported case of murine typhus caused by Rickettsia typhi in Mexico City. This is the first report of a case after almost 20 years since the last report. The species was confirmed by DNA sequencing and phylogenetic reconstruction.

6. Molecular epidemiology of 16S rRNA methyltransferase in Brazil: RmtG in Klebsiella aerogenes ST93 (CC4)
Abstract Aminoglycosides are a class of antibiotics that play a key role in antimicrobial treatment of Multidrug resistant (MDR) Gram-negative bacilli, typically in combination with β-lactams. Ribosomal 16S RNA modification by methyltransferases (e.g. RmtG) is an aminoglycoside resistance mechanism that, along with the occurrence carbapenem-resistant Entero

7. Mayaro fever in an HIV-infected patient suspected of having Chikungunya fever
Abstract Arboviruses impose a serious threat to public health services. We report a case of a patient returning from a work trip to the Amazon basin with myalgia, arthralgia, fever, and headache. During this travel, the patient visited riverside communities. Both dengue and Chikungunya fevers were first suspected, tested for, and excluded. Mayaro fever was t

8. PHYTOCHEMICAL AND PHYLOGENETIC ANALYSIS OF
Spondias (Anacardiaceae)This paper describes the correlation between the phenolic composition and the molecular phylogenetic reconstruction of five
Spondias species (Anacardiaceae). Two of these species (S. venulosa andSpondias sp.) occur in rainforest areas and the other three are widely distributed in Brazil (S. dulci Quím. Nova. Publicado em: 2015-07

9. Pseudorabies virus can be classified into five genotypes using partial sequences of UL44
Suid herpesvirus 1 (SuHV-1) is the causative agent of pseudorabies (PR), a disease of great importance due to the huge losses it causes in the swine industry. The aim of this study was to determine a method for genotyping SuHV-1 based on partial sequences of the gene coding for glycoprotein C (gC) and to elucidate the possible reasons for the variability of

10. Positive selection, molecular recombination structure and phylogenetic reconstruction of members of the family Tombusviridae: implication in virus taxonomy
A detailed study of putative recombination events and their evolution frequency in the whole genome of the currently known members of the family Tombusviridae, comprising 79 accessions retrieved from the international databases, was carried out by using the RECCO and RDP version 3.31β algorithms. The first program allowed the detection of potential recombin

11. Filogenia e evolução de Teiidae (Squamata: Reptilia) com ênfase em Cnemidophorus
This study aims to improve the knowledge of phylogeny, biogeography and diversity of Teiidae. The first chapter provides an analysis of phylogenetic relationships among teiid genera based on molecular and morphological data. The total combined analysis corroborated the monophyly of Tupinambinae, Teiinae, and cnemidophorines. We present an evolutionary scenar

12. Revisão taxonômica e estudos filogenéticos de Mimosa L. sect. Calothamnos Barneby (Leguminosae-Mimosoideae) / Taxonomicrevision and phylogenetic studies of Mimosa L. sect Calothamnos Barneby
TAXONOMIC REVISION AND PHYLOGENETIC STUDIES OF Mimosa L. sect. Calothamnos Barneby (Leguminosae-Mimosoideae). Mimosa is the second largest genus of Mimosoideae, after Acacia s.l., with about 530 species, mainly distributed in the Neotropics in diferent types of vegetations, from forests to deserts. Traditionally, the genus was divided into five sections: Mim
