    Abstract The function of uric acid (UA) in the genesis and evolution of chronic kidney disease (CKD) has motivated numerous studies, but the results remain inconclusive. We sought to conduct a systematic review and meta-analysis of cohort studies aiming to analyze the association of UA levels with the incidence and progression of CKD. Pubmed/Medline, Lilacs/Bireme and Web of Science were searched to identify eligible studies, following the PRISMA protocol. Data were presented for CKD incidence and progression separately. For the meta-analysis, studies with data stratified by subgroups according to serum UA levels were selected. The inverse variance-weighted random effects model was used to generate a combined effect estimate. Meta-regressions were performed to identify the causes of heterogeneity. The Newcastle-Ottawa Scale was used to assess the risk of bias. The publication bias was tested by funnel plot and Egger's test. Eighteen CKD incidence studies (n = 398,663) and six CKD progression studies (n = 13,575) were included. An inverse relationship was observed between UA levels and protection from CKD incidence and progression. Lower UA levels were protective for the risk of CKD incidence (RR 0.65 [95% CI 0.56-0.75]) and progression (RR 0.55 [95% CI 0.44-0.68]). UA seems to be implicated both in the genesis of CKD and its evolution.

    Abstract White-eared opossums (Didelphis albiventris) are well adapted to anthropized areas. The increased contact with domestic animals and humans mediates the transmission of arthropod-borne pathogens. Despite the worldwide occurrence of tick-borne Anaplasmataceae and Hepatozoidae species in a variety of vertebrates, few studies reported serological evidence or molecular detection of theses agentes in marsupials. Up to now, while Ehrlichia/Anaplasma spp. have only been detected in marsupials from Brazil, Hepatozoon spp. have been reported in marsupials from Chile, Australia and Brazil. The present work aimed to investigate, using molecular techniques and blood smear analysis, the presence of Ehrlichia spp., Anaplasma spp., and Hepatozoon sp. in the blood and ticks collected from D. albiventris in urban forest fragments from midwestern Brazil. Between May and December 2017, 43 D. albiventris (27 males and 16 females) were captured for blood and tick collection in the city of Campo Grande, state of Mato Grosso do Sul, midwestern Brazil. Ticks (46 Amblyomma dubitatum nymphs and 24 Amblyomma spp. larvae) were collected from 14 out 43 (32.5%) of the white-eared opossums. Panoptic-stained blood smears were performed using peripheral blood (tail tip) of the captured opossums. DNA extracted from blood and tick samples were subjected to PCR/qPCR assays for Anaplasmataceae agents (rrs, gltA, groEL, sodB, and dsb genes, and 23S-5S intergenic region) and Hepatozoon spp. (18S rRNA gene), followed by Sanger sequencing, BLASTn and phylogenetic analyses. An inclusion resembling Ehrlichia morulae was found in a white-eared opossum's monocyte from a blood smear stained with Panoptic. Five (11.63% [5/43]) white-eared opossums' blood samples and 7 (25% [7/28]) tick samples (2 pools of Amblyomma spp. larvae and 5 pools of A. dubitatum nymphs) were positive for Anaplasmataceae via a PCR assay targeting the conserved rrs gene. Phylogenetic analysis based on the rrs gene positioned three sequences obtained from opossums and ticks together as a subclade within the Ehrlichia canis clade. However, all samples were negative in a qPCR assay specific for E. canis based on the dsb gene. Phylogenetic analyses positioned the gltA and 23S-5S ITS sequences obtained from opossums' blood samples in a separate clade from the other validated Ehrlichia species. One (2.3% [1/43]) opossum blood sample was positive for the 18S rRNA gene of Hepatozoon sp. The phylogenetic analysis positioned the Hepatozoon sp. sequence obtained from a D. albiventris specimen in a clade with a sequence previously detected in a black storm petrel (Oceanodroma melania) from Mexico. All the other sequences of Hepatozoon sp. previously detected in marsupials from Brazil were positioned in a separated clade. The present work showed the occurrence of putative novel genotypes of Ehrlichia sp. and Hepatozoon sp. in white-eared opossums and associated A. dubitatum ticks from midwestern Brazil.

    Abstract Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) quickly spread worldwide, leading coronavirus disease 2019 (COVID-19) to hit pandemic level less than 4 months after the first official cases. Hence, the search for drugs and vaccines that could prevent or treat infections by SARS-CoV-2 began, intending to reduce a possible collapse of health systems. After 2 years, efforts to find therapies to treat COVID-19 continue. However, there is still much to be understood about the virus' pathology. Tools such as transcriptomics have been used to understand the impact of SARS-CoV-2 on different cells isolated from various tissues, leaving datasets in the databases that integrate genes and differentially expressed pathways during SARS-CoV-2 infection. After retrieving transcriptome datasets from different human cells infected with SARS-CoV-2 available in the database, we performed an integrative analysis associated with deep learning algorithms to determine differentially expressed targets mainly after infection. The targets found represented a fructose transporter (GLUT5) and a component of proteasome 26s. These targets were then molecularly modeled, followed by molecular docking that identified potential inhibitors for both structures. Once the inhibition of structures that have the expression increased by the virus can represent a strategy for reducing the viral replication by selecting infected cells, associating these bioinformatics tools, therefore, can be helpful in the screening of molecules being tested for new uses, saving financial resources, time, and making a personalized screening for each infectious disease.

    Abstract Objetivou-se e avaliar os efeitos da adição de óleo de soja nos parâmetros séricos e fisiológicos de equinos submetidos a exercício físico. Foram utilizadas 6 éguas da raça Crioula, com idade de quatro anos, e peso aproximado de 350 kg. Os tratamentos foram: Controle 5 kg de MS de aveia (Avena sativa) e 5 kg de MS de Capim Aruana (Panicum Jacq., cv. Aruana); Tratado: 3,52 kg de aveia (Avena sativa), 5 kg de MS de Capim Aruana (Panicum Jacq., cv. Aruana) e 500 g de óleo de soja. Foram efetuadas pesagens e coleta de sangue, no dia 0, 14 e 28 dias de experimento em jejum para análise dos parâmetros séricos. Aos 28 dias de experimentação os equinos foram submetidos a exercício, durante 30 minutos. Antes do início foram realizadas coletas, em jejum, pela manhã e imediatamente após o exercício, 10 minutos e 3 horas após o fim do exercício, além de aferir os parâmetros fisiológicos antes e logo após o exercício. Os valores apresentaram diferença significativa (P<0,05) para colesterol total, HDL, LDL, VLDL e triglicerídeo aos 14 dias de experimento, aos 28 dias diferença apenas para (P<0,05) colesterol total e LDL. Com a realização do exercício não houve diferença nos parâmetros séricos, mas observou-se diferença para os parâmetros fisiológicos entre os períodos de coleta. A adição de óleo de soja na dieta de equinos submetidos a exercício não interfere os parâmetros séricos, tornando-se assim uma alternativa para dietas energéticas.

    Abstract NANOTECHNOLOGY IN BRAZIL AND THE DEVELOPMENT OF PRODUCTS WITH ANTIMICROBIAL ACTIVITY. Due to the tremendous technological potential and applicability in various industry branches, nanotechnology investments have been increasing over the years. In particular, the control of microorganisms using nanomaterials with antimicrobial action has aroused great interest in the industry. This control makes it necessary in the most diverse situations, such as food conservation, pharmaceutical industry, hospital environments, and even domestic and commercial environments. This extraordinary interest is due, in particular, to the physical-chemical characteristics of materials on a nanoscale that attributes greater efficiency in combating microorganisms. Therefore, researchers and entrepreneurs have directed investments and efforts towards developing new products and/or new applications for antimicrobial products already existing on the market. In this work, we made a brief presentation of the history of nanotechnology in Brazil with a focus on Brazilian companies that developed products or services with nanomaterials with antimicrobial action, and on the description of some of the existing applications in the Brazilian market, highlighting the productive potential of the parents.
