    The 2021 re-emergence of yellow fever in non-human primates in the state of Rio Grande do Sul (RS), southernmost Brazil, resulted in the death of many howler monkeys (genus Alouatta) and led the state to declare a Public Health Emergency of State Importance, despite no human cases reported. In this study, near-complete genomes of yellow fever virus (YFV) recovered from the outbreak were sequenced and examined aiming at a better understanding of the phylogenetic relationships and the spatio-temporal dynamics of the virus distribution. Our results suggest that the most likely sequence of events involved the reintroduction of YFV from the state of São Paulo to RS through the states of Paraná and Santa Catarina, by the end of 2020. These findings reinforce the role of genomic surveillance in determining the pathways of distribution of the virus and in providing references for the implementation of preventive measures for populations in high risk areas

    Objective This study evaluated the fracture toughness (FT) of denture base and autopolymerizing reline resins, with and without thermocycling (T). Material and Methods Specimens of each material (denture base acrylic resin - Lucitone 550 – L; autopolymerizing reline resins - Ufi Gel Hard–UH, Tokuyama Rebase II-TR, New Truliner–NT and Kooliner-K), were produced, notched and divided into two groups (n=10): CG (control group of autopolymerizing reline resins and L): FT tests were performed after polymerization; TG (thermocycled group): FT tests were performed after T (5°C and 55°C for 5,000 cycles). Results: Results (MPa.m1/2) were analyzed by two-way ANOVA and Tukey's test (p=0.05). L exhibited the highest FT mean values in both groups (CG - 2.33; TG - 2.17). For the CG groups, NT showed the highest FT (1.64) among the autopolymerizing reline resins, and K the lowest (1.04). After T, when the autopolymerizing reline resins were compared, a statistically significant difference in FT was found only between the NT (1.46) and TR (1.00). Conclusions Thermocycling increased the FT of K and did not influence the FT of L, UH, TR and NT

    A leitura de textos científicos como uma possibilidade de análise do aprimoramento de gêneros do discurso

    Get PDF
    O presente trabalho propõe uma reflexão a respeito da importância da leitura em aulas de ciências, já que esta prática dá acesso à formação de cidadãos críticos, aproximando-os da cultura científica entendida como compreensão da própria ciência, sendo importante sua incorporação na formação inicial dos futuros professores de química, pois estes recebem uma formação essencialmente quantitativa, preocupada em enfatizar habilidades relacionadas à resolução de cálculos e problemas, desprezando o desenvolvimento de atividade que envolva leitura e escrita. Com isso objetivamos, analisar a evolução do gênero de discurso primário para o gênero de discurso secundário a partir da leitura de textos científicos, apresentando as licenciandos ou licenciados em química, possibilidades que os levem a mobilização para a incorporação da prática da leitura auxiliada pelas estratégias de leitura de Isabel Solé (1998) em suas ações pedagógicas futuras

    Fast surveillance response reveals the introduction of a new yellow fever virus sub-lineage in 2021, in Minas Gerais, Brazil

    BACKGROUND In Brazil, the yellow fever virus (YFV) is maintained in a sylvatic cycle involving wild mosquitoes and nonhuman primates (NHPs). The virus is endemic to the Amazon region; however, waves of epidemic expansion reaching other Brazilian states sporadically occur, eventually causing spillovers to humans. OBJECTIVES To report a surveillance effort that led to the first confirmation of YFV in NHPs in the state of Minas Gerais (MG), Southeast region, in 2021. METHODS A surveillance network was created, encompassing the technology of smartphone applications and coordinated actions of several research institutions and health services to monitor and investigate NHP epizootics. FINDINGS When alerts were spread through the network, samples from NHPs were collected and YFV infection confirmed by reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and genome sequencing at an interval of only 10 days. Near-complete genomes were generated using the Nanopore MinION sequencer. Phylogenetic analysis indicated that viral genomes were related to the South American genotype I, clustering with a genome detected in the Amazon region (state of Pará) in 2017, named YFVPA/MG sub-lineage. Fast YFV confirmation potentialised vaccination campaigns. MAIN CONCLUSIONS A new YFV introduction was detected in MG 6 years after the beginning of the major outbreak reported in the state (2015-2018). The YFV strain was not related to the sub-lineages previously reported in MG. No human cases have been reported, suggesting the importance of coordinated surveillance of NHPs using available technologies and supporting laboratories to ensure a quick response and implementation of contingency measures to avoid YFV spillover to humans

    Antimicrobial Resistance and Extended-Spectrum Beta-Lactamase Production in Enterobacteriaceae Isolates from Household Cats (Felis silvestris catus)

    Background: In Brazil, cats in households has recently increased dramatically, likely due to their lower space and care requirements. We need to know the health of these companion animal species, since they have behavioral patterns that make them an important link in the epidemiological chain. Extended spectrum beta-lactamase producer strains (ESBL) are resistant to penicillin, cephalosporin and monobactam, but they are susceptible to clavulanate. The goal of this study is to detect strains of Enterobacteriaceae that produce extended spectrum beta-lactamase (ESBL) and evaluate the bacterial resistance profile in isolated cats (Felis silvestris catus) that live in a city located at west of Parana state, Brazil.Materials, Methods & Results: Swabs were aseptically collected from the anal orifice and oral cavity of 49 female domestic cats that were healthy upon clinical and physical examination, a minimum age of one year, weighing up to 3 kg, and had attended a veterinary clinic specializing in cats, in order to, later, perform the isolation and bacterial identification, antimicrobial sensibility phenotypic test and the phenotypic test to detect ESBL producer strains. From the 98 swabs collected it was possible to perform the bacterial isolation in 68 samples; 40.81% isolated from anal orifice and 28.57% isolated from oral cavity. From rectal and oral cavities 77.50% and 71.42% of the isolated were identified as Escherichia coli respectively, being 2.94% considered ESBL producer strains. In relation to bacterial resistance the antibiotics that shown more resistance in anal orifice were ampicillin, amoxicillin, nalidixic acid, sulfazotrim, tetracycline and aztreonam. In oral cavity they were ampicillin, amoxicillin, cefoxitin, amoxicillin + clavulanate, aztreonam, ceftriaxone and nalidixic acid; and the bacterial resistance index shown that 39.70% were considered high level risk.Discussion: Household cats have a very important role in society, since the benefits they provide to their owners are clear, however, it is worth pointing out that these animals also pose risks to human health, caused by the transmission of zoonoses and also the possibility of transfer of antimicrobial resistance genes between bacteria of animal and human origin, as well as between bacteria of the normal microbiota and pathogenic microorganisms of diferents origins. Therefore, it is important to understand the health of these companion animal species, because they exhibit behavioral patterns that make them an important link in the epidemiological chain of potentially infectious microorganisms, which may show antimicrobial resistance. Extended spectrum beta-lactamase producer strains (ESBL) are resistant to penicillin, cephalosporin and monobactam, but they are susceptible to clavulanate. These enzymes hydrolyze the beta-lactam ring of the antibiotic structure, inactivating them. Nowadays bacterial resistance is considered to be one of the greatest problems in public health worldwide, as infections and diseases outbraks are caused by multiresistant bacteria are more and more frequent. The results of this study demonstrate the presence of strains of Enterobacteriaceae family associated to the high bacterial resistance, with samples that indicate ESBL producer strains in domiciled cats, in a city of west Parana state in Brazil. These results confirm that these cats can be considered as reservoirs of different microbial agents and resistance gens, being a health problem by the possibility of dissemination. The cat population is multiplying in a higher proportion compared to dogs and may probably became predominant in less than one decade. Due this situation and thinking about human, animal and environmental health new phenotypic studies to confirm the resistance gens and ESBL producers should be conducted in this specie

    The growing quest for sustainability in agricultural production systems has been pushing researchers to develop new technologies under different soil and climatic conditions. Based on this, and knowing the socioeconomic importance of the bean, the use of biological nitrogen fixation (BNF) is explored. Thus, the quest for quantitative knowledge of BNF at the phenological stages in a new bean line using promising and commercial strains becomes necessary. The objective of this study was to evaluate the strains UFLA 02 100 and CIAT 899 in the different phenological stages of the LEP 02 11 common bean strain using the biological nitrogen fixation. The experiment was conducted in a greenhouse on the Maringá-PR campus of the State University of Maringá. The design was a randomized complete block design in a 6x4 factorial scheme with four replications. The factor A comprised six nitrogen sources: Control, strain UFLA 02 100, strain CIAT 899, Nitrogen 60 kg ha-1, strain UFLA 02 100 + Nitrogen 30 kg ha-1, strain CIAT 899 + Nitrogen 30 kg ha-1 and the B factor is the phenological stages V4, R5, R6 and R8. The analyzed variables were: dry mass of nodules (DMN, grams/plant), dry mass of shoot (DMS, grams/plant), nitrogen content in shoot (NCS, %) and accumulation of nitrogen in shoot (ANS, grams/plant). For the statistical analysis of the data, the means test was used for the variables in the stages. The CIAT 899 strain statistically outperformed UFLA 02 100 for most variables and it was found that nitrogen fertilization negatively affected nodulation

    Suicide is motivated by multiple causes, and the abusive consumption of alcoholic beverages can be an important sign that individuals do not have physical and emotional control of themselves. To estimate the incidence of alcohol consumption, immediately before suicide, among people who died in 2018 in the Brazilian Federal District. This is a population-based study, of a descriptive and exploratory nature, of all deaths which occurred in the Brazilian Federal District from January 1 to December 31, 2018. Data were collected from the Mortality Information System and Police reports. The incidence and respective 95% confidence intervals were calculated. This study was approved by the Research Ethics Committee. The incidence of alcohol consumption just before the suicide was 18.6% (CI 95%: 18.56% to 18.62%). Males, blacks, trade workers, those without a partner, young people, and individuals with less than 8 years of study had the highest indicators. There was a greater percentage of alcohol consumption in the fall/winter, at the end of the month, in rural areas, in people who had never attempted suicide before and when the modus operandi was choking or hanging. The consumption of drugs, such as methamphetamine, ecstasy, amphetamine, and cannabis, was observed together with alcoholic beverages. The results of this research signaled an important public health problem, which is the use of alcohol to potentially encourage suicide. Effective public policies to tackle the abusive consumption of alcoholic beverages and suicide are necessary.O suicídio é motivado por múltiplas causas e o consumo abusivo de bebidas alcoólicas pode ser um sinal importante de que os indivíduos não têm controle físico e emocional de si mesmos.
