ABSTRACT In Brazil, Dengue, Zika and Chikungunya viruses constitute a major threat to the public health system. Simultaneous circulation of these arboviruses occurs in many regions of the world due to the expansion of transmission vectors. The infection by these arboviruses triggers similar symptoms during their acute phase. However, in some cases, severe symptoms may occur, leading to different types of disabilities and even death. In this context, considering the similarity of the symptoms, the problems caused by the infection of these arboviruses, and the increasing risk of coinfection in humans, the differential diagnosis of these infections is essential for clinical management and epidemiological investigation. Thus, this study aimed to identify, through diagnosis via Quantitative Polymerase Chain Reaction with Reverse Transcription, arbovirus coinfection in patients from the Tocantins state (Northern Brazil). A total of 495 samples were analyzed, three from which were determined to be a coinfection of Dengue and Chikungunya viruses. The data obtained here indicate the co-circulation and coinfection by Dengue and Chikungunya viruses in the Tocantins state. These results highlight the importance of monitoring the circulation of these arboviruses for the development of health actions that aim their prevention and combat, as well as their clinical and therapeutic management.

Abstract Caryocar brasiliense (Caryocaraceae) is a Neotropical tree species widely distributed in Brazilian Savannas. This species is very popular in central Brazil mainly by the use of its fruits in the local cuisine, and indeed it is one of the candidates, among Brazilian native plants, for fast track incorporation into cropping systems. Here we sequenced the complete chloroplast genome of C. brasiliense and used the data to access its genomic resources using high-throughput sequencing. The chloroplast exhibits a genome length of 165,793 bp and the typical angiosperm quadripartite structure with two copies of an inverted repeat sequence (IRa and IRb) of 34,902 bp each, separating a small single copy (SSC) region of 11,852 bp and a large single copy (LSC) region of 84,137 bp. The annotation analysis identified 136 genes being 87 protein-coding, eight rRNA and 37 tRNA genes. We identified 49 repetitive DNA elements and 85 microsatellites. A bayesian phylogenetic analysis helped to understand previously unresolved relationships in Malpighiales, placing Caryocaraceae as a separated group in the order, with high supported nodes. This study synthetizes valuable information for further studies allowing a better understanding of evolutionary patterns in the group and providing resources for future breeding programs.

RESUMO O Cerrado é considerado um dos "hotspots" mundiais de biodiversidade, em função da grande extensão de vegetação natural que vem sendo continuamente perdida e do elevado número de espécies endêmicas de plantas, que muitas vezes têm sido listadas como prioridades em programas de conservação e para estudos de genética de populações. A fim de verificar tendências nos estudos de genética de populações das espécies de plantas deste bioma, uma avaliação cienciométrica dos artigos publicados e disponíveis em diferentes bases de dados foi realizada. Um total de 171 publicações provenientes de 48 periódicos foi encontrada, entre os anos de 1999 a 2014, com o número de publicações aumentando significativamente nesse período. Noventa e uma espécies com diferentes formas de vida foram estudadas, usando diferentes tipos de marcadores moleculares. A análise cienciometrica dos artigos encontrados permitiu uma melhor compreensão do conhecimento atual sobre a genética de populações de plantas do bioma Cerrado.

ABSTRACT The Cerrado biome is considered one of the biodiversity hotspots in the world, due to both the large extent of natural vegetation that has been continually lost and the high number of endemic plant species. It has often been listed as a priority in conservation programs and in population genetic studies. In order to determine trends in plant population genetic studies in this biome, a scientometric evaluation of published and available articles in different databases was performed. A total of 171 publications from 48 journals was found between the years 1999 and 2014, with the number of publications increasing significantly during this period. Ninety-one species with different life forms were studied, using different types of molecular markers. These analyses confer a better understanding of the current knowledge of plant population genetics in the Cerrado biome.
