ABSTRACT: One of the main issues related to the management of forage legumes is the fact that these plants can be found in a broad diversity of morphology, structures and growth habits. This study evaluated the structural and productive characteristics of forage legumes with different growth habits [Clitoria ternatea L.; Desmanthus pernambucanus (L.) Thellung; and Stylosanthes spp. cv. Campo Grande], in response to two harvesting frequencies (60 and 90 days). The experimental design was completely randomized in blocks, with a split-plot scheme and four replications (n=4). The type of forage legume influenced the number of secondary branches, the number of leaves per branch, leaf area index (LAI), light interception (LI), percentage of leaves and stems (%), leaf/stem ratio, and pod production (P<0.05). D. pernambucanus had the lowest LI and LAI (P < 0.05). Stylosanthes spp. cv. Campo Grande and C. ternatea showed a greater leaf percentage and leaf/stem ratio (P < 0.05). There was an effect of the harvesting frequency on the percentage of stems, leaves, pod production, and total production (P < 0.05). Longer harvesting frequencies affected differently these legumes, especially the accumulation of stems in D. pernambucanus, which displayed an intense increase after 60 days of growth. The choice of the best harvesting frequency for these legumes evaluated should consider the proposal of the usage. In our study, it was shown that harvesting at 60 days did not affect the total forage mass accumulated, which possibly is the most advantageous choice.

RESUMO: Uma das principais questões relacionadas ao manejo de leguminosas forrageiras é o fato de que essas plantas podem ser encontradas em uma ampla diversidade de morfológica, estruturais e de hábitos de crescimento. O objetivo deste estudo foi avaliar características morfológicas, estruturais e produtivas de leguminosas forrageiras com diferentes hábitos de crescimento [Clitoria ternatea L.; Desmanthus pernambucanus (L.) Thellung; e Stylosanthes spp. cv. Campo Grande], em resposta a duas frequências de colheita (60 e 90 dias). O delineamento experimental foi inteiramente casualizado em blocos, com esquema de parcelas subdivididas e quatro repetições (n=4). O tipo de leguminosa forrageira influenciou no número de ramos secundários, número de folhas por ramo, índice de área foliar (IAF), interceptação luminosa (IL), porcentagem de folhas e colmos (%), razão folha/colmo e produção de vagens (P<0,05). D. pernambucanus apresentou os menores IL e IAF (P<0,05). Stylosanthes spp. cv. Campo Grande e C. ternatea apresentaram maior porcentagem de folhas e relação folha/colmo (P<0,05). Houve efeito da frequência de colheita na porcentagem de produção de hastes, folhas e vagens e na produção total (P<0,05). Frequências de colheita mais longas afetaram de forma diferente as leguminosas forrageiras avaliadas, principalmente o acúmulo de caules em D. pernambucanus, que apresentou aumento intenso após 60 dias de crescimento. A escolha da melhor frequência de colheita para essas leguminosas avaliadas deve levar em consideração a sua forma de uso. No presente estudo, foi demonstrado que a colheita aos 60 dias não afetou a massa forragem total acumulada, o que possivelmente é a escolha mais vantajosa.

Abstract This study analyzed the periodontal clinical data of individuals with a history of COVID-19 treated in a dental school during the pandemic in 2021 before vaccination. Methods: This analysis included individuals older than 18 years with no history of systemic disorders other than systemic arterial hypertension. Individuals who had COVID-19 were classified according to the World Health Organization as asymptomatic, with mild, moderate, severe, or critical symptoms. Results: A total of 95 individuals were evaluated, which included 24 with a history of COVID-19. Seventeen percent had been asymptomatic, 21% had mild, 25% moderate, 21% severe, and 17% critical symptoms, including intubation. Individuals with no history of COVID-19 presented significantly lower measurements of probing depth (p=0.003; Mann-Whitney test) and clinical attachment level (p=0.002) compared to individuals with a history of COVID-19. A significant negative association was found between bleeding on probing and the severity of characteristics of COVID-19 (rho= -0.233; p=0.023). Conversely, positive associations between the values of probing depth (rho= 0.292; p=0.004) and mean clinical attachment level (rho= 0.300; p=0.003) and the characteristics of COVID-19 were found. Conclusions: The periodontal data shows that patients who had COVID-19 before vaccination may present a worse periodontal status when compared to patients in the same clinical setting with no history of COVID-19. However, a more extensive study should confirm it with more participants.

Resumo Este estudo analisou os dados clínicos periodontais de indivíduos com histórico de COVID-19 tratados em uma escola de odontologia durante a pandemia em 2021, antes da vacinação. Métodos: Essa análise incluiu indivíduos maiores de 18 anos sem histórico de distúrbios sistêmicos, exceto hipertensão arterial sistêmica. Os indivíduos que tiveram COVID-19 foram classificados de acordo com a Organização Mundial da Saúde como assintomáticos, com sintomas leves, moderados, graves ou críticos. Resultados: 95 indivíduos foram avaliados, incluindo 24 com histórico de COVID-19. 17% eram assintomáticos, 21% tinham sintomas leves, 25% moderados, 21% graves e 17% críticos, incluindo intubação. Os indivíduos sem histórico de COVID-19 apresentaram medidas significativamente mais baixas de profundidade de sondagem (p=0,003; teste de Mann-Whitney) e nível de fixação clínica (p=0,002) em comparação com indivíduos com histórico de COVID-19. Foi encontrada uma associação negativa significativa entre o sangramento à sondagem e a gravidade das características da COVID-19 (rho= -0,233; p=0,023). Por outro lado, foram encontradas associações positivas entre os valores de profundidade de sondagem (rho = 0,292; p = 0,004) e o nível médio de apego clínico (rho = 0,300; p = 0,003) e as características da COVID-19. Conclusão: Os dados periodontais mostraram que os pacientes que tiveram COVID-19 antes da vacinação podem apresentar um pior estado periodontal quando comparados a pacientes no mesmo ambiente clínico sem histórico de COVID-19. No entanto, um estudo mais extenso deve ser realizado para confirmar tal achado com maior número de participantes.

Resumen: En | Texto: En | PDF: En

Abstract Objective: To assess the predictive value of selected growth phenotypes for neonatal morbidity and mortality in preterm infants < 30 weeks and to compare them with INTERGROWTH-21st (IG21). Methods: Retrospective analysis of data from the Brazilian Neonatal Research Network (BNRN) database for very low birth weight (VLBW) at 20 public tertiary-care university hospitals. Outcome: the composite neonatal morbidity and mortality (CNMM) consisted of in-hospital death, oxygen use at 36 weeks, intraventricular hemorrhage grade 3 or 4, and Bell stage 2 or 3 necrotizing enterocolitis. Selected growth phenotypes: small-for-gestational-age (SGA) defined as being < 3rd (SGA3) or 10th (SGA10) percentiles of BW, and large-for-gestational-age (LGA) as being > 97th percentile of BW. Stunting as being < 3rd percentile of the length and wasting as being < 3rd percentile of BMI. Single and multiple log-binomial regression models were fitted to estimate the relative risks of CNMM, comparing them to IG21. Results: 4,072 infants were included. The adjusted relative risks of CNMM associated with selected growth phenotypes were (BNRN/IG21): 1.45 (0.92–2.31)/1.60 (1.27–2.02) for SGA; 0.90 (0.55–1.47)/1.05 (0.55–1.99) for LGA; 1.65 (1.08–2.51)/1.58 (1.28–1.96) for stunting; and 1.48 (1.02–2.17) for wasting. Agreement between the two references was variable. The growth phenotypes had good specificity (>95%) and positive predictive value (70-90%), with poor sensitivity and low negative predictive value. Conclusion: The BNRN phenotypes at birth differed markedly from the IG21 standard and showed poor accuracy in predicting adverse neonatal outcomes.

Resumen: En | Texto: En | PDF: En

Abstract Objectives Evidence suggests that ketamine’s influence on brain-derived neurotrophic factor (BDNF) might be involved in its mechanism of rapid antidepressant action. We aimed to evaluate the differential impact of ketamine and esketamine on serum BDNF levels and its association with response patterns in treatment-resistant depression (TRD). Methods Participants (n = 53) are from a randomized, double-blind clinical trial comparing the efficacy of single-dose ketamine (0.5mg/kg, n = 27) and esketamine (0.25mg/kg, n = 26) in TRD. Depression severity was assessed before and 24 hours, 72 hours, and 7 days after the intervention, using the Montgomery-Åsberg Depression Rating Scale (MADRS). Blood samples were collected before infusion, 24 hours, and 7 days afterwards. Results There were no significant changes in BDNF levels at post-infusion evaluation points, and no difference in BDNF levels comparing ketamine and esketamine. Both drugs exhibited similar therapeutic effect. There was no association between BDNF levels and response to treatment or severity of depressive symptoms. Conclusion There was no significant treatment impact on BDNF serum levels – neither with ketamine nor esketamine – despite therapeutic response. These results suggest that ketamine or esketamine intervention for TRD has no impact on BDNF levels measured at 24 hours and 7 days after the infusion. This clinical trial is registered on the Japan Primary Registries Network: UMIN000032355.

Resumen: En | Texto: En | PDF: En

ABSTRACT This study aimed to evaluate the effect of water supply and sowing time on yield and yield components of two corn hybrids grown during offseason in the region of Dourados-MS, Brazil. The experimental design was randomized blocks in sub-divided plots, with four replications. In the main plot, two sowing dates were defined (2013 crop year: February 27 and March 27; and 2014 crop year: March 18 and April 5). In subplots, irrigation management systems were defined (irrigated and rainfed). Hybrids AS 1555 and AS 1590 were grown in the sub-plots. The parameters evaluated were plant height, ear insertion height, stem diameter, ear length and diameter, 100-grain weight, and grain yield. Regardless of irrigation and hybrid used, sowing time significantly affected corn yield, which responded to climate changes throughout crop cycle. Water supply increased corn yield, with the highest value being of 9338 kg ha-1 (156 bags ha-1) and obtained when irrigated AS 1555 hybrid was sown on February 27, 2013.

Resumen: En | Texto: En | PDF: En

Abstract The phenolic compound content, the antioxidant and α-amylase inhibition potentials of different extracts of the Plectranthus amboinicus, P. barbatus and P. ornatus were evaluated. We also evaluated the influence of plant growth and harvest time on the chemical composition of the essential oil (EO) of P. amboinicus, its antioxidant and anti-Candida activities and the α-amylase and lipoxygenase inhibitions. The turbo-extract of P. barbatus showed the greatest phenolic compound content and antioxidant activity. No α-amylase inhibition activity was observed in the analyzed extracts, but the turbo-extraction and refluxing extracts possessed high antioxidant activities. Protected cultivation and morning harvest conditions gave the best antioxidant activities, which was associated to the highest carvacrol content. P. amboinicus EO antioxidant activity could contribute to the reduction of oxidative stress in diabetes. Causal Candida strains of diabetic foot ulcers showed sensitivity to P. amboinicus EO. C. albicans and C. dubliniensis were the most sensitive of the selected Candida strains. Turbo-extracts or refluxing of the three species extracts and the EO of P. amboinicus should be considered as a potential candidate for the management the complications of type 2 diabetes.

Resumen: En | Texto: En | PDF: En

Intense stimulation of most living cells triggers the activation of immediate early genes, such as Fos and Jun families. These genes are important in cellular and biochemical processes, such as mitosis and cell death. The present study focused on determining the temporal expression pattern of Fos and Jun families in fibroblasts and neural stem cells of cerebellum, hippocampus, and subventricular zone (SVZ) of rats of different ages at 0, 0.5, 1, 3, and 6 h after stimulation with fibroblast growth factor (FGF)-2. In neonates, a similar expression pattern was observed in all cells analyzed, with lower expression in basal condition, peak expression at 0.5 h after stimulation, returning to baseline values between 1 and 3 h after stimulation. On the other hand, cells from adult animals only showed Fra1 and JunD expression after stimulation. In fibroblasts and hippocampus, Fra1 reached peak expression at 0.5 h after stimulation, while in the SVZ, peak level was observed at 6 h after stimulation. JunD in fibroblasts presented two peak expressions, at 0.5 and 6 h after stimulation. Between these periods, the expression observed was at a basal level. Nevertheless, JunD expression in SVZ and hippocampus was low and without significant changes after stimulation. Differences in mRNA expression in neonate and adult animals characterize the significant differences in neurogenesis and cell response to stimulation at different stages of development. Characterizing these differences might be important for the development of cell cultures, replacement therapy, and the understanding of the physiological response profile of different cell types.

Abstract The impact of high-speed exercise on the musculoskeletal system of young racehorses has been extensively discussed because of concerns regarding animal health and welfare. This study investigated the correlation between age, degree of ossification of the distal radial epiphysis, sex, and career longevity of Thoroughbred racehorses in Brazil from 2012 to 2015. We performed a retrospective evaluation of 286 dorsopalmar radiographs of the left radiocarpal region of young horses and their racing performance. Distal radial epiphyseal closure was classified into three degrees: A, B, or C. Performance data included the number of races raced, athletic career length, and the number of races per month. The variables were subjected to regression analysis. At the time of radiographic examination, male horses were significantly older than females, and horses with epiphyseal closure degrees differed with age. Age at first race was 33.08±3.81 months, the average of races raced was 18.32±15.14 races, athletic career duration was 20.37±13.82 months, and the number of races raced per month was 0.93±0.46 races. Age influenced (P>0.001) the distal radial epiphyseal closure on racehorses, but sex did not (P=0.218 for males and P=0.275 for females). An inverse association was observed between age at the first race, the number of races raced per month, and athletic career duration. The frequency of race and the age at the first race influenced athletic career duration.

Resumo O impacto do exercício de alta velocidade no sistema musculoesquelético de cavalos de corrida jovens tem sido amplamente discutido devido a preocupações com a saúde e o bem-estar animal. Este estudo investigou a correlação entre idade, grau de ossificação da epífise radial distal, sexo e longevidade da carreira de cavalos Puro Sangue Inglês de corrida no Brasil de 2012 a 2015. Realizamos uma avaliação retrospectiva de 286 radiografias dorsopalmar da região radiocarpica esquerda de cavalos jovens e seu desempenho de corrida. O fechamento epifisário radial distal foi classificado em três graus decrescentes: A, B ou C. Os dados de desempenho incluíram o número de corridas disputadas, duração da carreira atlética e o número de corridas por mês. As variáveis foram submetidas à análise de regressão. No momento do exame radiográfico, os cavalos machos eram significativamente mais velhos que as fêmeas, e os cavalos com graus de fechamento epifisário diferiram com a idade. A idade na primeira corrida foi de 33,08±3,81 meses, a média de corridas disputadas foi de 18,32±15,14 corridas, a duração da carreira atlética foi de 20,37±13,82 meses e o número de corridas realizadas por mês foi de 0,93±0,46 corridas. A idade influenciou (P>0,001) o fechamento da epífise radial distal em cavalos de corrida, mas o sexo não (P=0,218 para machos e P=0,275 para fêmeas). Uma associação inversa foi observada entre a idade na primeira corrida, o número de corridas disputadas por mês e a duração da carreira atlética. A frequência de corrida e a idade na primeira corrida influenciaram a duração da carreira atlética.

ABSTRACT The search for cultivation techniques that provide productive, social and environmental benefits to the agroecosystem is of great seriousness for the sustainable intensification of agriculture. This study aimed to determine the effect of crop cover crops on the soil attributes and development of bean plants treated with the consortium of bioagents Serratia marcencens + Trichoderma koningiopsis grown in the winter. The experiments were conducted for three crop seasons, in a randomized blocks design arranged in a 2 × 8 factorial scheme, with four replications. The treatments consisted of the combination of eight cover crops with two microbial treatments. The bioagents and the mix of cover crops, especially the treatment 2 (corn) and the mixes 3 (millet, Crotalaria ochroleuca, black oat, white oat, buckwheat and coracana grass) and 5 (black oat, buckwheat, millet, Piatã grass and C. Ocholeuca), provided significant increases in the soil chemical and biological quality, with increases in the contents of Ca, Mg, K, H + Al and organic matter, as well as in the main soil pathogens that affect the bean crop, concerning fallow. In addition, there was an increase in the number of pods per plant and grains per pod. The use of these technologies provided savings, if compared to the use of chemical fertilization.

RESUMO A busca por técnicas de cultivo que proporcionem benefícios produtivos, sociais e ambientais ao agroecossistema é de grande seriedade para a intensificação sustentável da agricultura. Objetivou-se determinar o efeito de coberturas vegetais nos atributos do solo e no desenvolvimento de feijoeiro tratado com o consórcio de bioagentes Serratia marcencens + Trichoderma koningiopsis, em cultivo de inverno. Os experimentos foram conduzidos por três safras agrícolas, com delineamento em blocos casualizados, em esquema fatorial 2 x 8, com quatro repetições. Os tratamentos foram compostos pela combinação de oito coberturas vegetais e dois tratamentos microbianos. Os bioagentes e a mistura de plantas de cobertura, especialmente o tratamento 2 (milho) e as misturas 3 (milheto, Crotalaria ochroleuca, aveia preta, aveia branca, trigo mourisco e capim coracana) e 5 (aveia preta, trigo mourisco, milheto, capim Piatã e C. ochroleuca), proporcionaram aumentos significativos na qualidade química e biológica do solo, com aumento nos teores de Ca, Mg, K, H + Al e matéria orgânica, bem como dos principais patógenos do solo que afetam a cultura do feijoeiro, em relação ao pousio. Além disso, houve aumento no número de vagens por planta e de grãos por vagem. O uso dessas tecnologias proporcionou economia, em relação ao uso da adubação química.

Abstract Aim: This study aims to compare the sleep parameters in Paralympic powerlifting athletes during days with and without training, and to analyze the relationship between the training load and sleep on the same day and the relationship between the previous night's sleep and the training load of the following day. Methods: Actigraphy was used to analyze the sleep parameters of 11 Paralympic powerlifting athletes for 14 days (7 days without and with training), whereas Ratings of Perceived Exertion (RPE) analysis was used to assess training load. In addition, the Horne and östberg chronotype questionnaire and the Epworth Sleepiness Scale were applied. Results: Athletes show morning and indifferent chronotype and low daytime sleepiness. We found that on training days, sleep onset latency (SOL) was lower (average 5.3 min faster), whereas total sleep time (TST) and sleep efficiency (SE) were higher (TST averaged 169 min and SE 7% higher) compared to non-training days. In addition, the TST of the night before the training days correlated positively with the RPE of the following day, and the training volume correlated negatively with the SE of the same day. Conclusion: Our findings show that Paralympic powerlifting training had positive effects in increasing TST and SE and decreasing SOL on training days. These results show the positive effects of this type of training in improving sleep in athletes with physical disabilities. In addition, a good night's sleep the day before training can make it possible to put more effort into the next day's training. Therefore, guiding athletes to sleep more before training with more intense loads is recommended.

Resumo Objetivo Caracterizar mudanças em indicadores antropométricos em idosos e investigar se o excesso de peso associou-se com menor velocidade da marcha (VM), com base em medidas realizadas a um intervalo de nove anos. Métodos Estudo de coorte com idosos (≥65 anos), realizado em 2008-2009 (linha de base) e 2016-2017 (seguimento) em Campinas/SP e Ermelino Matarazzo/SP, Brasil. Foram aferidas medidas de peso corporal, estatura, circunferência da cintura (CC) e do quadril (CQ), usadas para obter os indicadores: índice de massa corporal (IMC), razão cintura-estatura (RCE), razão cintura-quadril (RCQ) e índice de conicidade (Índice C). Os testes T e de Wilcoxon para amostras pareadas foram usados para estimar as diferenças. Resultados Foram analisadas informações de 537 idosos (70,0% mulheres) com idade média de 72,2 anos na linha de base e 80,7 anos no seguimento. Após nove anos, os homens apresentaram reduções significativas do peso corporal, estatura e IMC, e aumento do Índice C. Nas mulheres, observou-se declínio do peso, estatura e IMC, e elevação da CC, CQ, RCE, RCQ e Índice C. Observaram-se variações percentuais de: -3,89% (peso), -0,36% (estatura), -4,18% (IMC) e +2,27% (Índice C) nos homens; -2,95% (peso), -0,65% (estatura), -0,73% (IMC), +3,33% (CC), +1,59% (CQ), +3,45% (RCE), +2,27% (RCQ) e +4,76% (Índice C) nas mulheres. O excesso de peso associou-se com maiores chances de estabilidade e de novos casos de menor VM no seguimento. Conclusão Foram identificadas mudanças no peso, estatura, IMC, nos indicadores de obesidade abdominal, especialmente nas mulheres, e associação entre excesso de peso e menor VM.

Abstract Objective To characterize changes in anthropometric indicators in older adults and investigate whether being overweight was associated with lower gait speed (GS), based on measurements taken at an interval of nine years. Methods Cohort study with older adults (≥65 years), conducted in 2008-2009 (baseline) and 2016-2017 (follow-up) in the city of Campinas/SP and in Ermelino Matarazzo/SP, Brazil. Body weight, height, waist circumference (WC) and hip (HC) measurements were taken and used to determine the following indicators: body mass index (BMI), waist-to-height ratio (WHtR), waist-to-hip ratio (WHR) and conicity index (C index). The T and Wilcoxon tests for paired samples were used to estimate the differences. Results Information from 537 older adults (70.0% women) with a mean age of 72.2 years at baseline and 80.7 years at follow-up were analyzed. After nine years, the men showed significant decreases in weight, height and BMI, and an increase in the C index. In women, decreases in weight, height and BMI, and increases in WC, HC, WHtR, WHR and C index were observed. The percentage variations observed were: -3.89% (weight), -0.36% (height), -4.18% (BMI) and +2.27% (C index) among men; -2.95% (weight), -0.65% (height), -0.73% (BMI), +3.33% (WC), +1.59% (HC), +3.45% (WHtR), +2.27% (WHR) and +4.76% (C-Index) among women. Being overweight was associated with greater odds ratio of stability and new cases of lower GS at follow-up. Conclusion Changes were identified in weight, height, BMI, and indicators of abdominal obesity, especially in women, together with an association between being overweight and lower GS.

Resumo O fitoquímico natural látex de Euphorbia milii var. hislopii é um dos mais promissores moluscicidas naturais para o controle de Biomphalaria glabrata, tendo sido amplamente estudado em condições laboratoriais como controle seletivo da transmissão da esquistossomose. No entanto, o efeito deste produto em B. glabrata infectada por outro helminto, ainda não tinha sido investigado. O presente trabalho tem por objetivo avaliar o efeito do látex de E. milii var. hislopii na sobrevivência e atividade reprodutiva de B. glabrata infectada por Angiostrongylus cantonensis. Para isso, foram formados os seguintes grupos: controle (C), exposto (E), infectado (I) e infectado e exposto em diferentes intervalos de tempo de infecção (1 dia – I+E-1D, 7 dias – I+E-7D, 14 dias – I+E-14D, 21 dias – I+E-21D e 28 dias – I+E-28D). A infecção experimental foi realizada com larvas L1 de A. cantonensis e a exposição com 0,08 mg/L (LC50) do látex de E. milii por um período de 24 horas. Foram analisados os efeitos do látex de E. milii quanto à sobrevivência dos moluscos ao longo de quatro semanas, aos parâmetros reprodutivos e as possíveis alterações histofisiopatológicas na gônada e na glândula de albúmen dos moluscos analisados. Em relação à sobrevivência foi possível observar redução de mais de 50% nos grupos expostos ao látex (E e I + E) em comparação ao grupo controle. Quanto ao número de massas ovígeras, ovos e número médio de moluscos eclodidos pode-se observar um aumento significativo no grupo I+E-1D na 4ª semana em comparação ao grupo controle e as demais semanas no mesmo grupo. Larvas de A. cantonensis foram observadas na glândula e na glândula de albúmen, a partir dos 21º dias e 28º dia de infecção nos grupos I e I+E, respectivamente, com a formação de granuloma-like. Nesses períodos de observação e nesses grupos pode-se observar na glândula de albúmen, um aumento do conteúdo de galactogênio, o que influenciou a postura dos ovos, sugerindo um fenômeno de compensação da fecundidade. Foi possível concluir que ambos agentes estressores, infecção por A. cantonensis e exposição ao látex de E. milii influenciou diretamente a sobrevivência e os parâmetros reprodutivos de B. glabrata.

Abstract The natural phytochemical latex of Euphorbia milii var. hislopii is one of the most promising natural molluscicides for the control of Biomphalaria glabrata, and has been widely studied under laboratory conditions for selective control of schistosomiasis transmission. However, the effect of this product on B. glabrata infected by other helminths had not yet been investigated. The present study reports evaluation of the effect of E. milii var. hislopii latex on the survival and reproductive activity of B. glabrata infected by Angiostrongylus cantonensis. For this purpose, the following groups were formed: control (C), exposed (E), infected (I) and infected and exposed for different time intervals (1 day - I+E-1D, 7 days - I+E-7D, 14 days - I+E-14D, 21 days - I+E-21D and 28 days - I+E-28D). The experimental infection was performed with L1 larvae of A. cantonensis and exposure to 0.08 mg/L (LC50) of E. milii latex for a period of 24 hours. We analyzed the effects of E. milii latex on the survival of snails during four weeks, reproductive parameters and possible histophysiopathological changes in the gonad and albumen gland of the snails. Regarding survival, there was reduction of more than 50% in the groups exposed to latex (E and I + E) compared to the control group. As for the number of ovigerous masses, eggs, and average number of hatched snails, significant increases were observed in the I+E-1D group at the 4th week compared to the control group and the other weeks in the same group. Angiostrongylus cantonensis larvae were observed in the gonad and albumen gland from day 21 and 28 of infection in groups I and I+E, respectively, with granuloma-like formation. At these observation periods and in these groups, an increase in galactogen was observed in the albumen gland, which influenced egg laying, suggesting the existence of a fecundity compensation mechanism phenomenon. It was possible to conclude that both stressors – A. cantonensis infection and exposure to E. milii latex – directly influenced the survival and reproductive parameters of B. glabrata.

Resumen: En | Texto: En | PDF: En

Abstract This report describes the photoacoustic and electron paramagnetic resonance investigations of Brazilian and Cuban zeolites. Photoacoustic optical absorption measurements indicate the presence of iron (Fe 3 +) ions with their respective transition bands for both zeolites. Two species of manganese (Mn 2 + and Mn 3 +) were identified in the Cuban sample and the electronic transitions assigned. Iron and manganese ions were confirmed through nonradiative relaxation ( τ) and characteristic diffusion ( τ β) times evaluation, whose values were found to be τ BRA = 5.40 ms, τ CUB = 4.60 ms, τ β BRA = 387 μs and τ β CUB = 305 μs. Crystal field (Dq- BRA/Dq- CUB = 1048 cm − 1/945 cm − 1) plus Racah (B- BRA/B- CUB = 457 cm − 1/813 cm − 1 and C- BRA/C- CUB = 3655 cm − 1/2496 cm − 1) parameters were assessed as well. Paramagnetic resonance corroborated Fe 3 + ions present in the Brazilian zeolite occupying sites showing axial and/or rhombic symmetry distortions. For the Cuban sample, results reveal the characteristic hyperfine sextet lines of Mn 2 + overlapping the Fe 3 + line. Values of Landé factor and isotropic hyperfine splitting constant were found to be 2.0 and 9.7 mT, respectively. This tells us that the Mn 2 + lies in octahedral symmetry probably replacing calcium ions and point towards an ionic bonding character of the Mn 2 + and its surroundings.

Resumen: En | Texto: En | PDF: En

ABSTRACT The dispersion of Diceraeus melacanthus (Dallas) from soybean (first crop season) to maize (second crop season) is facilitated by the presence of weeds (e.g. Commelina benghalensis) and soybean grains on the ground. Understanding insect development and behavior on different food sources is important to develop pest management strategies. Thus, three independent experiments were conducted to study D. melacanthus nymph development, and adult preference for feeding and oviposition in different food source scenarios in the field. The first two trials studied development and food preference of D. melacanthus related to different food sources (C. benghalensis branches, moistened soybean grain + soybean seedlings, maize seedlings + C. benghalensis branches, moistened soybean grains + maize seedlings, moistened soybean grains + C. benghalensis branches, maize seedlings, as well as a standard diet). The third trial evaluated D. melacanthus oviposition preferences between the aforementioned plants. Overall, moistened soybean grains resulted in better nutritional quality, thus being crucial for D. melacanthus development, triggering faster nymph development as well as better overall adult fitness. The combination of soybean grains and maize seedlings or C. benghalensis branches showed great potential to benefit D. melacanthus, since these complementary food sources improved stink bug fitness, increasing mainly adult longevity, fecundity and egg viability. Therefore, it can be concluded that in order to reduce D. melacanthus outbreaks in second season maize, it is important to reduce soybean harvest loss (reducing, therefore, moistened soybean grain on the ground) and eliminate stink bug associated plants like C. benghalensis.
