Resistance Risk Assessment of Spodoptera frugiperda (Lepidoptera: Noctuidae) and Diatraea saccharalis (Lepidoptera: Crambidae) to Vip3Aa20 Insecticidal Protein Expressed in Corn.

Transgenic Agrisure Viptera 3 corn that expresses Cry1Ab, Vip3Aa20, and EPSPS proteins and Agrisure Viptera expressing Vip3Aa20 are used for control of Spodoptera frugiperda (J.E. Smith) and Diatraea saccharalis (F.) in Brazil. To support a resistance management program, resistance risk assessment studies were conducted to characterize the dose expression of Vip3Aa20 protein and level of control against these species. The Vip3Aa20 expression in Agrisure Viptera 3 and Agrisure Viptera decreased from V6 to V10 stage of growth. However, Vip3Aa20 expression in Agrisure Viptera 3 at V6 and V10 stages was 13- and 16-fold greater than Cry1Ab, respectively. The Vip3Aa20 expression in lyophilized tissue of Agrisure Viptera 3 and Agrisure Viptera diluted 25-fold in an artificial diet caused complete larval mortality of S. frugiperda and D. saccharalis. In contrast, lyophilized tissue of Bt11 at the same dilution does not provide complete mortality of these species. Agrisure Viptera 3 and Agrisure Viptera also caused a high level of mortality against S. frugiperda and D. saccharalis. Moreover, 100% mortality was observed for S. frugiperda larvae (neonates through fifth-instar larvae) when fed in corn with the Vip trait technology. Viptera corn achieves a high level of control against S. frugiperda and D. saccharalis providing a high dose, which is an important determination to support the refuge strategy for an effective resistance management program.

Baseline susceptibility and monitoring of Brazilian populations of Spodoptera frugiperda (Lepidoptera: Noctuidae) and Diatraea saccharalis (Lepidoptera: Crambidae) to Vip3Aa20 insecticidal protein.

The genetically modified maize expressing Vip3Aa20 insecticidal protein from Bacillus thuringiensis Berliner is abiotechnological option for the control of Spodoptera frugiperda (J.E. Smith) and Diatraea saccharalis (F.) in Brazil. To support an Insect Resistance Management program, we conducted studies of baseline susceptibility and monitoring of Brazilian populations of S. frugiperda and D. saccharalis to the Vip3Aa20 insecticidal protein. Neonates were exposed to Vip3Aa20 applied on artificial diet surface. Mortality and growth inhibition were assessed after 7 d. All populations were susceptible to Vip3Aa20. The LC50 ranged from 92.38 to 611.65 ng Vip3Aa20/cm2 for 16 populations of S. frugiperda (6.6-fold variation), and between 61.18 and 367.86 ng Vip3Aa20/cm2 for 6 populations of D. saccharalis (sixfold variation). The EC50 ranged from 21.76 to 70.09 and 48.65 to 163.60 ng Vip3Aa20/cm2 for S. frugiperda and D. saccharalis, respectively. There was a low interpopulation variation in susceptibility to Vip3Aa20, which represents the natural geographic variation in the response, and not the variation caused by previous exposure to selection pressure. For these two pests, the diagnostic concentrations of 2,000 and 3,600 ng of Vip3Aa20/cm2 caused high mortality. These diagnostic concentrations will be used in resistance monitoring programs in Brazil.

Selection of Soybean and Cowpea Cultivars with Superior Performance under Drought Using Growth and Biochemical Aspects.

Identifying cultivars of leguminous crops exhibiting drought resistance has become crucial in addressing water scarcity issues. This investigative study aimed to select soybean and cowpea cultivars with enhanced potential to grow under water restriction during the vegetative stage. Two parallel trials were conducted using seven soybean (AS3810IPRO, M8644IPRO, TMG1180RR, NS 8338IPRO, BMX81I81IPRO, M8808IPRO, and BÔNUS8579IPRO) and cowpea cultivars (Aracê, Novaera, Pajeú, Pitiúba, Tumucumaque, TVU, and Xique-xique) under four water levels (75, 60, 45, and 30% field capacity-FC) over 21 days. Growth, water content, membrane damage, photosynthetic pigments, organic compounds, and proline levels were analyzed. Drought stress significantly impacted the growth of both crops, particularly at 45 and 30% FC for soybean and 60 and 45% FC for cowpea plants. The BÔNUS8579IPRO and TMG1180RR soybean cultivars demonstrated the highest performance under drought, a response attributed to increased amino acids and proline contents, which likely help to mitigate membrane damage. For cowpea, the superior performance of the drought-stressed Xique-xique cultivar was associated with the maintenance of water content and elevated photosynthetic pigments, which contributed to the preservation of the photosynthetic efficiency and carbohydrate levels. Our findings clearly indicate promising leguminous cultivars that grow under water restriction, serving as viable alternatives for cultivating in water-limited environments.

Emotional, hyperactivity and inattention problems in adolescents with immunocompromising chronic diseases during the COVID-19 pandemic.

OBJECTIVE: To assess factors associated with emotional changes and Hyperactivity/Inattention (HI) motivated by COVID-19 quarantine in adolescents with immunocompromising diseases. METHODS: A cross-sectional study included 343 adolescents with immunocompromising diseases and 108 healthy adolescents. Online questionnaires were answered including socio-demographic data and self-rated healthcare routine during COVID-19 quarantine and validated surveys: Strengths and Difficulties Questionnaire (SDQ), Pittsburgh Sleep Quality Index (PSQI), Pediatric Quality of Life Inventory 4.0 (PedsQL4.0). RESULTS: The frequencies of abnormal emotional SDQ scores from adolescents with chronic diseases were similar to those of healthy subjects (110/343 [32%] vs. 38/108 [35%], p = 0.548), as well as abnormal hyperactivity/inattention SDQ scores (79/343 [23%] vs. 29/108 [27%], p = 0.417). Logistic regression analysis of independent variables associated with abnormal emotional scores from adolescents with chronic diseases showed: female sex (Odds Ratio [OR = 3.76]; 95% Confidence Interval (95% CI) 2.00‒7.05; p < 0.001), poor sleep quality (OR = 2.05; 95% CI 1.08‒3.88; p = 0.028) and intrafamilial violence during pandemic (OR = 2.17; 95% CI 1.12‒4.19; p = 0.021) as independently associated with abnormal emotional scores, whereas total PedsQL score was inversely associated with abnormal emotional scores (OR = 0.95; 95% CI 0.93‒0.96; p < 0.0001). Logistic regression analysis associated with abnormal HI scores from patients evidenced that total PedsQL score (OR = 0.97; 95% CI 0.95‒0.99; p = 0.010], changes in medical appointments during the pandemic (OR = 0.39; 95% CI 0.19-0.79; p = 0.021), and reliable COVID-19 information (OR = 0.35; 95% CI 0.16‒0.77; p = 0.026) remained inversely associated with abnormal HI scores. CONCLUSION: The present study showed emotional and HI disturbances in adolescents with chronic immunosuppressive diseases during the COVID-19 pandemic. It reinforces the need to promptly implement a longitudinal program to protect the mental health of adolescents with and without chronic illnesses during future pandemics.

A identidade da direita em narrativas de seus militantes numa universidade brasileira / The identity of the right-wing in narratives of its militants in a brazilian university / La identidad de la derecha en las narrativas de sus militantes en una universidad brasileña

Em junho de 2013, emergiram no espaço público brasileiro diferentes grupos de direita rebelados contra o Partido dos Trabalhadores, que governava o Brasil naquele momento liderando uma grande coalizão de centro-esquerda. Desde então, uma nova direita se posiciona no debate político nacional, militando nas universidades e em outros contextos institucionais e mobilizando uma retórica agressiva contra o discurso de esquerda. O objetivo deste estudo é identificar os diferentes atributos da identidade da direita formulados em narrativas de militantes de direita de uma universidade pública brasileira, as contradições no conteúdo dessa identidade e os recursos retórico-discursivos mobilizados em sua construção. Com o uso do método de análise de discurso, foram analisadas transcrições de entrevistas realizadas com nove militantes de direita, alunos de uma universidade pública nordestina. Esses militantes mencionam três grupos políticos como constituintes da direita (os conservadores, os liberais e os libertários), mas somente dois são usados como categorias de autoidentificação: os conservadores e os libertários. Atributos identitários como o apreço pela verdade, a defesa da liberdade, a desconfiança em relação às mudanças abruptas e a valorização da família e da religiosidade cristã foram afirmados como definidores da identidade da direita. Em vários momentos, no entanto, os militantes produziam enunciados que contradiziam alguns desses atributos, revelando o caráter ambíguo e contraditório do discurso da militância estudada.(AU)

In June 2013, different right-wing groups emerged in the Brazilian public space rebelling against the Partido dos Trabalhadores, which ruled Brazil at the time leading a large center-left coalition. Since then, a new right-wing has positioned itself in the national political debate, militating in universities and other institutional contexts, and mobilizing an aggressive rhetoric against the leftist discourse. This study aims to identify the different attributes of the right-wing identity formulated in the narratives of right-wing militants in a Brazilian public university, the contradictions in the content of that identity, and the rhetorical-discursive resources mobilized in its construction. We analyzed transcripts of interviews conducted with nine right-wing activists, students from a public university in the Northeast using the speech analysis method. These militants mention three political groups as constituents of the right-wing (conservatives, liberals, and libertarians), but only two are used as categories of self-identification: conservatives and libertarians. Identity attributes such as an appreciation for the truth, the defense of freedom, a distrust of abrupt changes, and the appreciation for the family and Christian religiosity were affirmed as defining the identity of the right-wing. At various times, however, the militants produced statements that contradicted some of these attributes, revealing the ambiguous and contradictory character of the studied militancy discourse.(AU)

Bacterial culture and antibiotic sensitivity from the ocular conjunctiva of horses / Cultura e sensibilidade bacteriana da conjuntiva ocular de equinos

ABSTRACT: The aim of this study was to identify the conjunctival bacterial flora of healthy horses in Brasilia (Distrito Federal, Brazil), and to evaluate the antimicrobial susceptibility of the isolated strains. We examined 200 eyes of 100 healthy adult horses without any eye problems, belonging to the 1st Regiment of the Cavalry Guard (RCG) of the Brazilian Army in Brasilia. Samples were collected from the inferior conjunctival fornix of both eyes. Drug sensitivity test was performed with the antibiotics gentamicin (10µg), tobramycin (10µg), chloramphenicol (30µg) and ciprofloxacin (5µg). Of the 200 samples collected, 131 (65.5%) were considered positive for bacterial growth. A total of 208 bacterial strains belonging to 19 genera were isolated, where there was prevalence of gram-positive bacteria (65%), with Staphylococcus sp. being the species of greatest incidence. It was observed that 94, 85, 81 and 68% of the isolates were sensitive to ciprofloxacin, gentamicin, chloramphenicol and tobramycin, respectively. These results can guide the empirical selection antimicrobial therapy for infections of the ocular surface of horses, pending the identification of the etiologic agent.

RESUMO: Objetivou-se identificar a flora bacteriana conjuntival de cavalos saudáveis, residentes de Brasília (Distrito Federal - Brasil), e avaliar a susceptibilidade antimicrobiana das cepas isoladas. Foram avaliados 200 olhos de 100 equinos hígidos, adultos, saudáveis e sem alterações oculares, provenientes do 1o Regimento de Cavalaria de Guarda (RCG) do Exército de Brasília. As amostras foram coletadas do fórnix conjuntival inferior de ambos os olhos. O teste de sensibilidade foi realizado para os antimicrobianos: gentamicina (10mcg), tobramicina (10mcg), cloranfenicol (30mcg) e ciprofoxacino (5mcg). Das 200 amostras coletadas, 131 (65,5%) foram consideradas positivas para o crescimento bacteriano. Um total de 208 bactérias pertencentes a 19 gêneros foram isoladas, verificando-se prevalência de bactérias gram-positivas (65%), sendo Staphylococcus sp, a espécie de maior incidência. Foi observado que 94%, 85%, 81% e 68% das bactérias isoladas foram sensíveis ao ciprofloxacino, à gentamicina, ao cloranfenicol e à tobramicina, respectivamente. Tais resultados podem direcionar a escolha empírica da terapêutica antimicrobiana nas afecções da superfície ocular de equinos, enquanto se aguarda a identificação do agente etiológico.
