Adaptation and feasibility assessment of a dating violence prevention program for girls in foster care.

BACKGROUND: Dating violence in adolescence is a serious public health issue due to its significant impact on mental health and its significant predictive value for intimate partner violence in adulthood. Universal and selective programs can contribute to the prevention of this issue. Nonetheless, there are few selective programs with evidence of feasibility in contexts of social vulnerability. OBJECTIVE: The present study examined evidence of the feasibility of a dating violence selective prevention program for girls in foster care by monitoring process indicators during the implementation phase of a pilot study. METHODS: The program, originally designed for adolescents in the general population, was adapted to the context of girls at risk. The pilot study was conducted in the southern region of Brazil and involved the participation of six girls aged between 15 and 17. Both quantitative and qualitative measures were used, and the data were explored through frequency analysis, the Jacobson and Truax test, and content analysis. RESULTS: The study identified favorable evidence regarding demand, acceptability, and adaptation of the intervention. On the other hand, contextual and institutional barriers hindered recruitment and restricted the reach of the intervention. CONCLUSION: Although there are changes to be made to improve the program's applicability in its specific context, it should be emphasized that this study provides evidence to maintain the methods and content of the intervention.

Plaque Reduction Neutralization Test (PRNT) Accuracy in Evaluating Humoral Immune Response to SARS-CoV-2.

Massive vaccination positively impacted the SARS-CoV-2 pandemic, being a strategy to increase the titers of neutralizing antibodies (NAbs) in the population. Assessing NAb levels and understanding the kinetics of NAb responses is critical for evaluating immune protection. In this study, we optimized and validated a PRNT50 assay to assess 50% virus neutralization and evaluated its accuracy to measure NAbs to the original strain or variant of SARS-CoV-2. The optimal settings were selected, such as the cell (2 × 105 cells/well) and CMC (1.5%) concentrations and the viral input (~60 PFU/well) for PRNT-SARS-CoV-2 with cut-off point = 1.64 log5 based on the ROC curve (AUC = 0.999). The validated PRNT-SARS-CoV-2 assay presented high accuracy with an intraassay precision of 100% for testing samples with different NAb levels (low, medium, and high titers). The method displays high selectivity without cross-reactivity with dengue (DENV), measles (MV), zika (ZIKV), and yellow fever (YFV) viruses. In addition, the standardized PRNT-SARS-CoV-2 assay presented robustness when submitted to controlled variations. The validated PRNT assay was employed to test over 1000 specimens from subjects with positive or negative diagnoses for SARS-CoV-2 infection. Patients with severe COVID-19 exhibited higher levels of NAbs than those presenting mild symptoms for both the Wuhan strain and Omicron. In conclusion, this study provides a detailed description of an optimized and validated PRNT50 assay to monitor immune protection and to subsidize surveillance policies applied to epidemiologic studies of COVID-19.

Empowering Riverine Communities in the Amazon: Strategies for Preventing Rabies.

Rabies, caused by the Lyssavirus genus, is a highly lethal zoonotic disease transmitted by animals such as bats and domestic and wild carnivores to humans, claiming nearly 100% of lives. In Brazil, recent evidence suggests an increasing role of bats in human deaths from rabies, particularly in the Amazon region. This neglected tropical disease disproportionately affects impoverished and vulnerable populations in rural areas, where approximately 80% of human cases are concentrated. This article presents research conducted in riverine communities of the Tapajós/Arapiuns Extractive Reserve in Brazil to combat rabies in September 2022. The study adopted a participatory and collaborative approach, involving community members, healthcare professionals, and educators. Prioritizing proactive interventions, the health team administered prophylactic vaccinations to 30 individuals residing in communities exposed to the Lyssavirus. Educational activities focused on dispelling myths and raising awareness about preventive measures, with 100% of individuals reporting prior doubts about the disease, emphasizing the essential nature of the clarification, especially regarding preventive aspects. This study underscores the importance of community involvement, personalized interventions, and ongoing education to effectively combat rabies. By reinforcing public health policies and promoting health education, we can empower communities to take proactive measures in rabies prevention, leading to a reduction in incidence and an improvement in quality of life.

Incorporation of bioactive glass-ceramic into coconut oil for remineralization of incipient carious lesions.

This study evaluated the efficacy of incorporating different concentrations of bioactive glass-ceramic (Biosilicate) into coconut oil on the remineralizing potential and surface roughness of white spot lesions. Fragments (6 x 6 x 2mm) of bovine teeth were sectioned and initial microhardness (KHN) and surface roughness (Ra) readings were obtained. The samples were submitted to cariogenic challenge to form white spot lesions and were separated into six groups (n=13): 1) Artificial Saliva (AS); 2) Coconut Oil (CO); 3) CO+2% Biosilicate (CO+2%Bio); 4) CO+5% Biosilicate (CO+5%Bio); 5) 2% Biosilicate Suspension (2% Bio) and 6) 5% Biosilicate Suspension (5% Bio). The treatments for 1 cycle/day were: immersion into the treatments for 5 minutes, rinsing in distilled water, and storage in artificial saliva at 37ºC. After 14 days, KHN and Ra readings were taken. The surface roughness alteration ((Ra) was analyzed (Kruskal-Wallis, Dunn's post-test, p<0.05). CO+2%Bio had higher (p = 0.0013) (Ra followed by CO+5%Bio (p = 0.0244) than AS. The relative KHN and remineralization potential were analyzed (ANOVA, Tukey, p<0.05), and 5% Bio treatment presented a higher relative microhardness than all other groups (p>0.05). The remineralizing potential of all the treatments was similar (p > .05). When Biosilicate was added, the pH of the suspensions increased and the alkaline pH remained during the analysis. Biosilicate suspension is more efficient than the incorporation of particles into coconut oil at white spot lesion treatment. In addition to the benefits that coconut oil and Biosilicate present separately, their association can enhance the remineralizing potential of Biosilicate.

Metabolomic analysis reveals stress tolerance mechanisms in common bean (Phaseolus vulgaris L.) related to treatment with a biostimulant obtained from Corynebacterium glutamicum.

Microbial biostimulants have emerged as a sustainable alternative to increase the productivity and quality of important crops. Despite this, the effects of the treatment on plant metabolism are poorly understood. Thus, this study investigated the metabolic response of common bean (Phaseolus vulgaris) related to the treatment with a biostimulant obtained from the extract of Corynebacterium glutamicum that showed positive effects on the development, growth, and yield of crops previously. By untargeted metabolomic analysis using UHPLC-MS/MS, plants and seeds were subjected to treatment with the biostimulant. Under ideal growth conditions, the plants treated exhibited higher concentration levels of glutamic acid, nicotiflorin and glycosylated lipids derived from linolenic acid. The foliar application of the biostimulant under water stress conditions increased the chlorophyll content by 17% and induced the accumulation of flavonols, mainly quercetin derivatives. Also, germination seed assays exhibited longer radicle lengths for seeds treated compared to the untreated control even in the absence of light (13-18% increase, p-value <0.05). Metabolomic analysis of the seeds indicated changes in concentration levels of amino acids (tryptophan, phenylalanine, tyrosine, glutamine, and arginine) and their derivatives. The results point out the enhancement of abiotic stress tolerance and the metabolic processes triggered in this crop associated with the treatment with the biostimulant, giving the first insights into stress tolerance mechanisms in P. vulgaris.

Inactivated and Immunogenic SARS-CoV-2 for Safe Use in Immunoassays and as an Immunization Control for Non-Clinical Trials.

Successful SARS-CoV-2 inactivation allows its safe use in Biosafety Level 2 facilities, and the use of the whole viral particle helps in the development of analytical methods and a more reliable immune response, contributing to the development and improvement of in vitro and in vivo assays. In order to obtain a functional product, we evaluated several inactivation protocols and observed that 0.03% beta-propiolactone for 24 h was the best condition tested, as it promoted SARS-CoV-2 inactivation above 99.99% and no cytopathic effect was visualized after five serial passages. Moreover, RT-qPCR and transmission electron microscopy revealed that RNA quantification and viral structure integrity were preserved. The antigenicity of inactivated SARS-CoV-2 was confirmed by ELISA using different Spike-neutralizing monoclonal antibodies. K18-hACE2 mice immunized with inactivated SARS-CoV-2, formulated in AddaS03TM, presented high neutralizing antibody titers, no significant weight loss, and longer survival than controls from a lethal challenge, despite RNA detection in the oropharyngeal swab, lung, and brain. This work emphasizes the importance of using different techniques to confirm viral inactivation and avoid potentially disastrous contamination. We believe that an efficiently inactivated product can be used in several applications, including the development and improvement of molecular diagnostic kits, as an antigen for antibody production as well as a control for non-clinical trials.

Contracepção pós-parto e pós-abortamento: um compilado das evidências atuais / Postpartum and post-abortion contraception: a compilation of current evidences

Idealmente, a contracepção deve ser iniciada o mais precocemente possível após o parto ou após o abortamento, permitindo que as mulheres sejam protegidas contra uma gravidez não programada subsequente. O objetivo desta revisão é discutir a contracepção no pós-parto e pós-aborto, por meio da análise de ensaios clínicos e metanálises, além das principais diretrizes internacionais, com ênfase nas indicações e contraindicações, tempo de início do uso dos métodos contraceptivos e possíveis complicações. Nesta revisão não sistemática, são discutidos os principais métodos contraceptivos: dispositivos intrauterinos, métodos somente de progestagênios, métodos hormonais combinados, métodos de barreira, método de amenorreia lactacional e esterilização. O aconselhamento contraceptivo pós-parto deve começar durante o pré-natal e, em pacientes após abortamento, durante a internação hospitalar. Todas as mulheres devem ter acesso a informações claras sobre cada método contraceptivo, e o processo de tomada de decisão deve ser compartilhado com o médico assistente. Idealmente, métodos de contracepção reversíveis de longa duração devem ser priorizados em relação aos outros. Em conjunto, todas as evidências demonstram que o melhor método para cada paciente é aquele que combine altas taxas de segurança com o desejo da paciente de iniciá-lo e mantê-lo pelo tempo que desejar.

Contraception should ideally be started as early as possible after childbirth or abortion to allow women to be protected against a subsequent unplanned pregnancy. The aim of this review is to discuss postpartum and postabortion contraception, through the analysis of clinical trials and meta-analyses, in addition to the main international guidelines, with emphasis on indications and contraindications, time to start contraceptive method and possible complications. In this review, the main contraceptive methods are discussed: intrauterine devices, progestin-only methods, combined hormonal methods, barrier methods, lactational amenorrhea method and sterilization. Postpartum contraceptive counseling should start during prenatal care and during hospital stay in post-abortion patients. All women should have access to clear information about each contraceptive method and the decision-making process must be shared. Ideally, long acting reversible contraception methods should be prioritized over others. Taken together, all the evidence shows that the best method for each patient is the one that combines high safety rates with the patient's desire to start and maintain it for as long as she wants.

Integrative omics analyses of the ligninolytic Rhodosporidium fluviale LM-2 disclose catabolic pathways for biobased chemical production.

BACKGROUND: Lignin is an attractive alternative for producing biobased chemicals. It is the second major component of the plant cell wall and is an abundant natural source of aromatic compounds. Lignin degradation using microbial oxidative enzymes that depolymerize lignin and catabolize aromatic compounds into central metabolic intermediates is a promising strategy for lignin valorization. However, the intrinsic heterogeneity and recalcitrance of lignin severely hinder its biocatalytic conversion. In this context, examining microbial degradation systems can provide a fundamental understanding of the pathways and enzymes that are useful for lignin conversion into biotechnologically relevant compounds. RESULTS: Lignin-degrading catabolism of a novel Rhodosporidium fluviale strain LM-2 was characterized using multi-omic strategies. This strain was previously isolated from a ligninolytic microbial consortium and presents a set of enzymes related to lignin depolymerization and aromatic compound catabolism. Furthermore, two catabolic routes for producing 4-vinyl guaiacol and vanillin were identified in R. fluviale LM-2. CONCLUSIONS: The multi-omic analysis of R. fluviale LM-2, the first for this species, elucidated a repertoire of genes, transcripts, and secreted proteins involved in lignin degradation. This study expands the understanding of ligninolytic metabolism in a non-conventional yeast, which has the potential for future genetic manipulation. Moreover, this work unveiled critical pathways and enzymes that can be exported to other systems, including model organisms, for lignin valorization.

The treatments for 1 cycle/day were: immersion into the treatments for 5 minutes, rinsing in distilled water, and storage in artificial saliva at 37ºC. After 14 days, KHN and Ra readings were taken. The surface roughness alteration ((Ra) was analyzed (Kruskal-Wallis, Dunn's post-test, p<0.05). CO+2%Bio had higher (p = 0.0013) (Ra followed by CO+5%Bio (p = 0.0244) than AS. The relative KHN and remineralization potential were analyzed (ANOVA, Tukey, p<0.05), and 5% Bio treatment presented a higher relative microhardness than all other groups (p>0.05). The remineralizing potential of all the treatments was similar (p > .05). When Biosilicate was added, the pH of the suspensions increased and the alkaline pH remained during the analysis. Biosilicate suspension is more efficient than the incorporation of particles into coconut oil at white spot lesion treatment. In addition to the benefits that coconut oil and Biosilicate present separately, their association can enhance the remineralizing potential of Biosilicate.

Resumo Este estudo avaliou a eficácia da incorporação de diferentes concentrações de vitrocerâmica bioativa (biosilicato) ao óleo de coco no potencial remineralizante e na rugosidade superficial de lesões de manchas brancas. Fragmentos (6 x 6 x 2mm) de dentes bovinos foram seccionados e as leituras iniciais de microdureza (KHN) e rugosidade superficial (Ra) foram obtidas. As amostras foram submetidas ao desafio cariogênico para formação de lesões de manchas brancas e foram separadas em seis grupos (n=13): 1) Saliva Artificial (AS); 2) Óleo de Coco (CO); 3) CO+2% Biosilicato (CO+2%Bio); 4) CO+5% Biosilicato (CO+5%Bio); 5) Suspensão de Biosilicato 2% (2% Bio) e 6) Suspensão de Biosilicato 5% (5% Bio). Os tratamentos de 1 ciclo/dia foram: imersão nos tratamentos por 5 minutos, enxágue em água destilada e armazenamento em saliva artificial a 37ºC. Após 14 dias, foram feitas as leituras de KHN e Ra. A alteração da rugosidade superficial ((Ra) foi analisada (Kruskal-Wallis, pós-teste de Dunn, p<0,05). CO+2%Bio apresentou maior (p = 0,0013) (Ra seguido de CO+5%Bio (p = 0,0244) do que AS. O KHN relativo e o potencial de remineralização foram analisados (ANOVA, Tukey, p<0,05), e o tratamento 5% Bio apresentou uma microdureza relativa maior do que todos os outros grupos (p>0,05). A suspensão de biosilicato é mais eficiente que a incorporação de partículas ao óleo de coco no tratamento de lesões de mancha branca. Além dos benefícios que o óleo de coco e o Biosilicato apresentam separadamente, sua associação pode amplificar o potencial remineralizante do Biosilicato.

Citrus aurantium L. and synephrine improve brown adipose tissue function in adolescent mice programmed by early postnatal overfeeding.

Introduction and aims: Obesity is a multifactorial condition with high health risk, associated with important chronic disorders such as diabetes, dyslipidemia, and cardiovascular dysfunction. Citrus aurantium L. (C. aurantium) is a medicinal plant, and its active component, synephrine, a ß-3 adrenergic agonist, can be used for weight loss. We investigated the effects of C. aurantium and synephrine in obese adolescent mice programmed by early postnatal overfeeding. Methods: Three days after birth, male Swiss mice were divided into a small litter (SL) group (3 pups) and a normal litter (NL) group (9 pups). At 30 days old, SL and NL mice were treated with C. aurantium standardized to 6% synephrine, C. aurantium with 30% synephrine, isolated synephrine, or vehicle for 19 days. Results: The SL group had a higher body weight than the NL group. Heart rate and blood pressure were not elevated. The SL group had hyperleptinemia and central obesity that were normalized by C. aurantium and synephrine. In brown adipose tissue, the SL group showed a higher lipid droplet sectional area, less nuclei, a reduction in thermogenesis markers related to thermogenesis (UCP-1, PRDM16, PGC-1α and PPARg), and mitochondrial disfunction. C. aurantium and synephrine treatment normalized these parameters. Conclusion: Our data indicates that the treatment with C. aurantium and synephrine could be a promising alternative for the control of some obesity dysfunction, such as improvement of brown adipose tissue dysfunction and leptinemia.

Assessment of Biodiversity in Food Consumption Studies: A Systematic Review.

The assessment of food biodiversity has gained importance in nutrition due to the positive association between the diversity of foods consumed and the quality of diets. To date, however, we do not know systematically how food consumption studies address food biodiversity. Our objective with this paper was to characterize how food consumption studies address biodiverse foods, both in terms of (i) new methods capable of overcoming the limitations of existing methods, and (ii) indicators capable of measuring the contribution of biodiversity to nutrition. We conducted a systematic review based on the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA), using four databases: Web of Science, Medline/PubMed (via National Library of Medicine), Scopus, and Google Scholar. We selected papers focused on the consumption of biodiverse foods without time constraints. In addition, we assessed the methodological quality of the studies we selected. We reviewed a total of 22 studies, and summarized the methods and indicators most used. We found that some researchers used biodiversity mapping strategies based on ethnographic approaches before the dietary assessment. Regarding dietary assessment tools, retrospective direct methods were the most used by researchers. We list 23 indicators used by the authors, among them the Dietary Species Richness (DSR), used in 18% of the studies. Studies that used biodiversity mapping strategies based on ethnographic approaches before the dietary assessment portrayed the local availability of biodiverse foods more consistently, i.e., presented lists with local edible species satisfactorily identified. We believe researchers in the future can avoid many of the limitations of current methods by ensuring that teams are interprofessional. We emphasize that most of the indicators we summarized are not sensitive enough to biodiversity since they do not measure edible resources at the species level. In this sense, the DSR is promising, because it fills information gaps, especially in the case of wild or neglected species.

Applying biochemical and structural characterization of hydroxycinnamate catabolic enzymes from soil metagenome for lignin valorization strategies.

The biocatalytic production of fuels and chemicals from plant biomass represents an attractive alternative to fossil fuel-based refineries. In this context, the mining and characterization of novel biocatalysts can promote disruptive innovation opportunities in the field of lignocellulose conversion and valorization. In the present work, we conducted the biochemical and structural characterization of two novel hydroxycinnamic acid catabolic enzymes, isolated from a lignin-degrading microbial consortium, a feruloyl-CoA synthetase, and a feruloyl-CoA hydratase-lyase, named LM-FCS2 and LM-FCHL2, respectively. Besides establishing the homology model structures for novel FCS and FCHL members with unique characteristics, the enzymes presented interesting biochemical features: LM-FCS2 showed stability in alkaline pHs and was able to convert a wide array of p-hydroxycinnamic acids to their respective CoA-thioesters, including sinapic acid; LM-FCHL2 efficiently converted feruloyl-CoA and p-coumaroyl-CoA into vanillin and 4-hydroxybenzaldehyde, respectively, and could produce vanillin directly from ferulic acid. The coupled reaction of LM-FCS2 and LM-FCHL2 produced vanillin, not only from commercial ferulic acid but also from a crude lignocellulosic hydrolysate. Collectively, this work illuminates the structure and function of two critical enzymes involved in converting ferulic acid into high-value molecules, thus providing valuable concepts applied to the development of plant biomass biorefineries. KEY POINTS: • Comprehensive characterization of feruloyl-CoA synthetase from metagenomic origin. • Novel low-resolution structures of hydroxycinnamate catabolic enzymes. • Production of vanillin via enzymatic reaction using lignocellulosic hydrolysates.

ABSTRACT Objective to identify in women of reproductive age, with cancer and during chemotherapy treatment, the guidelines on fertility preservation and reproductive planning and to know the information provided by the health team. Methods descriptive study, conducted with premenopausal women diagnosed with cancer and undergoing chemotherapy. Data collection was performed with the support of an instrument with sociodemographic information about cancer and its treatments, information regarding the preservation of fertility and the use of contraceptive methods before and after cancer diagnosis. Data analysis was performed using descriptive statistics. Results the average age of the 49 participants was 38.2 years (SD=6.1) and 79.6% were being treated for breast cancer. Regarding the information received about the importance of reproductive planning, 77.6% of participants reported that they were oriented and 59.2% received such guidance from the medical team. However, regarding counseling on methods to maintain fertility, only 6.1% of participants were counseled. Conclusion and Implications for practice consideration should be given to the importance of expert counseling and the maintenance of active decision making by women about preserving their fertility.

Effectiveness of hippotherapy and therapeutic horseback riding on balance in hemiparetic patients after stroke / Efetividade da hipoterapia e da equoterapia terapêutica no equilíbrio de pacientes hemiparéticos pós-acidente vascular cerebral

Abstract Introduction: Stroke is one of the leading causes of disability and death worldwide. Individuals who suffered stroke present numerous functional limitations. Hippo-therapy (HPOT) is proposed as capable of promoting the recovery of postural balance in patients with neurological impairment. Objective: To analyze published articles, seeking the effects of HPOT on changes in postural balance, through the Berg Balance Scale (BBS), in individuals with stroke. Methods: We conducted a systematic review and meta-analysis of studies published on the electronic databases PubMed, VHL, SCIELO, Cochrane, SCOPUS, WoS, and Cinahl. Keywords: "hippotherapy", "horseback riding" and "stroke" linked by the OR and AND boolean operators. The research was restricted to clinical trials in an adult population with a history of stroke. Results: Four articles were included in this meta-analysis, which used HPOT as an intervention to improve postural balance. Three studies used a mechanical device (horseback riding), and the horse. The age ranged from 61 to 71 years, being more predominant the male sex. Sessions ranged from 6 to 12 weeks of 20 to 30 minutes per session. Quality analysis using the PEDro scale demonstrated scores ranging from 6 to 8 points in the selected studies. Overall, treatment with mechanical and conventional therapy resulted in an improvement in the total BBS score. As compared with conventional therapy just studies with horseback riding was superior to conventional therapy to improve postural balance in hemiparetic stroke patients. Conclusion: There are few studies of high quality; then, it is not possible to evaluate the effectiveness of HPOT using a horse or a mechanic simulator in patients with stroke when compared with conventional therapy. Future studies could clarify if HPOT has potential benefits as a complementary therapeutic strategy to conventional physiotherapy to promote the improvement of postural balance after stroke.

Resumo Introdução: O acidente vascular encefálico (AVE) é uma das principais causas de incapacidade e morte em todo o mundo. Existem diferentes prospostas terapêuticas para melhorar o equilíbrio postural de hemiparéticos após AVE, mas a efetividade de técnicas como a hipoterapia ainda está por ser esclarecida. Objetivo: Avaliar através da Escala de Equilíbrio de Berg (EEB) a efetividade da hipoterapia para melhorar o equilíbrio postural em pacientes hemiparéticos após acidente vascular encefálico em comparação à terapia convencional Métodos: Uma revisão sistemática foi conduzida com buscas nas bases de dados eletrônicas PubMed, BVS, SCIELO, Cochrane, SCOPUS, WoS e Cinahl. Palavras-chave: "hippotherapy", "horseback riding" e "stroke" ligadas pelos operadores booleanos OR e AND. A pesquisa foi restrita a ensaios clínicos numa população adulta com histórico de AVE. Resultados: Após a análise dos estudos, foram incluídos nessa metanálise quatro artigos que utilizaram a hipoterapia como intervenção para melhora do controle postural e equilíbrio postural. Três artigos utilizaram hipoterapia com simulador mecânico e um estudo realizou com cavalos. O grupo de comparação foi a fisioterapia convencional. A idade variou de 61 a 71 anos, sendo mais predominante o sexo masculino. As sessões, com duração de 20 a 30 minutos, variaram entre 6 e 12 semanas. A análise de viés dos estudos com a escala PEDro revelou pontuações de 6 a 8 pontos. O resultado de três dos quatro ensaios clínicos sugere que o simulador mecânico e convencional resultou em melhora estatisticamente significativa do escore total da EEB. Conclusão: Uma vez que há poucos estudos de alta qualidade, não é possível estabelecer a efetividade da hipoterapia utilizando cavalos ou simulador mecânico para promover a melhoria no equilíbrio postural em pacientes sobreviventes após AVE quando comparada ao tratamento convencional. Estudos futuros podem esclarecer se a hipoterapia pode ser considerada um tratamento complementar para melhoria do equilíbrio postural após AVE.

A recuperação da memória operacional visual não é afetada por flicker cromático / The retrieval from visual working memory is not affected by chromatic flicker / La recuperación de la memoria operativa visual no es afectada por el flicker cromático

Nós investigamos o efeito da informação visual irrelevante (IVI) na recuperação da informação na memória de trabalho. Os participantes realizaram uma tarefa de reconhecimento visual. Em metade das provas, uma dica retroativa espacial foi apresentada no intervalo de retenção. A IVI, um flicker cromático, com frequências de 1,0 Hz, 7,3 Hz e 15,3 Hz, foi apresentada no intervalo entre dica e teste. A dica melhorou a acurácia e a rapidez na tarefa de reconhecimento. O flicker não afetou o desempenho. A dica retroativa pode permitir a recuperação da informação para um estado ativo e pode tê-la protegido da interferência do flicker.

We investigated the effect of irrelevant visual information (IVI) on retrieving information from working memory. Participants performed a visual recognition task. In half of the trials, a retroactive spatial cue was presented in the retention interval. The IVI, a chromatic flicker, with frequencies of 1.0 Hz, 7.3 Hz, and 15.3 Hz, was presented in the interval between cue and test. The cue improved the accuracy and speed of the recognition task. The flicker did not affect performance. The retroactive cue may allow the retrieval of information to an active state and may have protected it from the flicker interference.

Sofosbuvir shows a protective effect against vertical transmission of Zika virus and the associated congenital syndrome in rhesus monkeys.

The outbreaks of Zika virus (ZIKV) infection in Brazil, 2015-2016, were associated with severe congenital malformations. Our translational study aimed to test the efficacy of the antiviral agent sofosbuvir (SOF) against vertical transmission of ZIKV and the associated congenital syndrome (CZS), using a rhesus monkey model. Eight pregnant macaques were successfully infected during the organogenesis phase with a Brazilian ZIKV strain; five of them received SOF from two to fifteen days post-infection. Both groups of dams showed ZIKV-associated clinical signals, detectable ZIKV RNA in several specimens, specific anti-ZIKV IgM and IgG antibodies, and maternal neutralizing antibodies. However, malformations occurred only among non-treated dam offspring. Compared to non-treated animals, all SOF-treated dams had a shorter ZIKV viremia and four of five neonates had undetectable ZIKV RNA in blood and tissue samples. These results support further clinical evaluations aiming for the prevention of CZS.
