Abstract: Pig farming is an important component of the livestock sector at a global scale since pork is the most widely produced and consumed meat in the world. This study aimed to evaluate the effects of diets containing different levels of fermented coffee husk flour on the productive performance of pigs and economic viability in pig farming. Coffee husks were incorporated with probiotics based on Moringa oleifera Lam leaf extracts. Five gilts between 3 to 5 months of age, with an initial average weight of around 13.38 kg, were used. The experiment was conducted using a Latin Square Design, with 5 treatments and 5 replications. The treatments were a control treatment (T0) without coffee husks in the diet; and treatments T1, T2, T3, and T4 with coffee husks at 4%, 6%, 8%, and 10% in the diet, respectively. The statistical analysis showed that T1, which contained 4% fermented coffee husks in the diet, was the most efficient diet formulation with respect to the rest of the treatments. The animals that received T1 showed a high increase in average daily weight, with an average value of 867.70 g; and a better feed conversion rate, requiring only 3.57 kg to produce one kilogram of meat. The results of a descriptive yield analysis on feed cost showed that T1 could generate a higher yield of about $6.04 per kilogram of meat sold in the local market compared to the other treatments. Therefore, it is concluded that the incorporation of fermented coffee husks at 4% into pig diets can improve pig productive performance and reduce feed costs.

ABSTRACT: This clinical case report aims to describe the development of periradicular and perimplant cystic lesions resulted from the intimate contact of the apical region of osseointegrated implants of dental roots, and discuss the reasons fo r failure of the guided bone regeneration procedure associated with platelet rich fibrin and leukocytes, this process was used to the treatment of the first case. Case Reports. Three cases were reported, two cases described the close contact between the tooth roots and the osseointegrated implants and another with a distance of 1.08 mm. All cases realized a radiographic, and they had not periapical lesions before contact with the apical region of the osseointegrated implants on the roots of the teeth. In the case with the largest cystic extension, the procedure was: removal of the osseointegrated implant with apicectomy of the neighboring teeth, excisional biopsy of the lesion, and grafting using the technique of guided bone regeneration associated with L-PRF. All three cases, endodontic treatment was performed on the neighboring teeth within 2 years of survival of the osseointegrated implants in order to reverse the existing lesion. Results. The diagnostic hypothesis of the three cases was periradicular and peri-implant lesion, arising from a contact of the apical region of the osseointegrated implant with the adja cent tooth. The distance of 1.08 mm between the apices did not ensure normality of the periradicular and peri-implant tissues. The intimate contact caused lesions of different extents and root fractures. Conclusion. Premature contact of the osseointegrated implant with the root region of the neighboring tooth may lead to the development of periradicular and peri-implant lesions, suggesting that it is not possible to control this infectious process with endodontic treatment of the injured tooth.

RESUMEN: Este reporte de caso clínico tuvo como objetivo describir el desarrollo de lesiones quísticas perirradiculares y periimplantarias resultantes del contacto íntimo de la región apical de implantes osteointegrados de raíces dentales, y además discutir las razones del fracaso del procedimiento de regeneración ósea guiada asociado a fibrina rica en plaquetas y leucocitos. Este proceso se utilizó para el tratamiento del primer caso. Se reportaron tres casos, en dos casos se describieron el estrecho contacto entre las raíces de los dientes y los implantes osteointegrados y en el otro se determinó una distancia de 1,08 mm. En los tres casos se realizó una radiografía y se determinó que no existían lesiones periapicales, antes del contacto con la región apical de los implantes osteointegrados, en las raíces de los dientes. En el caso de mayor extensión quística, el procedimiento fue: extracción del implante osteointegrado con apicectomía de los dientes vecinos, biopsia excisional de la lesión e injerto mediante la técnica de regeneración ósea guiada asociada a L-PRF. En los tres casos, el tratamiento de endodoncia se realizó en los dientes vecinos dentro de los 2 años de supervivencia de los implantes osteointegrados para revertir la lesión existente. La hipótesis diagnóstica de los tres casos fue lesión perirradicular y periimplantaria, originada por un contacto de la región apical del implante osteointegrado con el diente adyacente. La distancia de 1,08 mm entre los ápices no aseguraba la normalidad de los tejidos perirradiculares y periimplantarios. El contacto íntimo provocó lesiones de diferente extensión y fracturas radiculares. El contacto prematuro del implante osteointegrado con la región radicular del diente vecino puede conducir al desarrollo de lesiones perirradiculares y periimplantarias, lo que sugiere que no es posible controlar este proceso infeccioso con tratamiento endodóntico del diente lesionado.

ABSTRACT The occurrence of water with high concentrations of salts hinders the expansion of irrigated agriculture in the semi-arid region of the Brazilian Northeast, making it necessary to adopt strategies capable of minimizing the effects of salt stress on plants. In this context, the objective of present study was to evaluate the effects of hydrogen peroxide application on water relations, gas exchange, photosynthetic pigments, and growth of guava cv. Paluma under irrigation with saline waters in the seedling formation stage. A randomized block design was used, in a 5 × 4 factorial scheme, with three replicates, with five levels of electrical conductivity of water - ECw (0.3, 1.3, 2.3, 3.3, and 4.3 dS m-1) and four concentrations of hydrogen peroxide - H2O2 (0, 25, 50, and 75 µM). Irrigation water salinity above 0.3 dS m-1 increased electrolyte leakage in the leaf blade and reduced the relative water content, synthesis of photosynthetic pigments, gas exchange, and growth of seedlings of guava cv. Paluma, at 80 days after sowing. Foliar application of hydrogen peroxide at concentrations of up to 75 µM reduces the relative water content in the leaf blade of guava seedlings and did not mitigate the effects of salt stress on guava plants in the seedling formation stage.

RESUMO A ocorrência de água com elevadas concentrações de sais dificulta a expansão da agricultura irrigada no semiárido do Nordeste brasileiro, tornando-se necessária a adoção de estratégias capazes de minimizar os efeitos do estresse salino sobre as plantas. Neste contexto, objetivou-se avaliar os efeitos da aplicação de peróxido de hidrogênio nas relações hídricas, nas trocas gasosas, nos pigmentos fotossintéticos e no crescimento de goiabeira cv. Paluma sob irrigação com águas salinas na formação de mudas. Foi utilizado o delineamento em blocos casualizados, em esquema fatorial 5 × 4, com três repetições, sendo cinco níveis de condutividade elétrica da água - CEa (0,3; 1,3; 2,3; 3,3 e 4,3 dS m-1) e quatro concentrações de peróxido de hidrogênio - H2O2 (0; 25; 50 e 75 µM). A salinidade da água de irrigação acima de 0,3 dS m-1 aumentou o extravasamento de eletrólitos no limbo foliar, reduziu o conteúdo relativo de água, a síntese de pigmentos fotossintéticos, as trocas gasosas e o crescimento das mudas de goiabeira cv. Paluma, aos 80 dias após a semeadura. A aplicação foliar de peróxido de hidrogênio em concentrações de até 75 µM, reduz o conteúdo relativo de água no limbo foliar de mudas de goiabeira e não ameniza os efeitos do estresse salino em plantas de goiabeira na fase de formação de mudas.

Resumo Os microRNAs (miRNAs) são reconhecidos como biomarcadores do diabetes mellitus tipo 2 (DM2), úteis para a compreensão do metabolismo da doença, e possuem grande potencial como alvos terapêuticos. O aumento da expressão de BDNF e IGF1 está altamente envolvido nos benefícios as vias de insulina e glicose, porém, são regulados negativamente em condições de resistência à insulina, enquanto seu aumento de expressão está correlacionado com a melhora do metabolismo da glicose e da insulina. Estudos sugerem a regulação desses genes por microRNA em vários contextos diferentes, proporcionando uma nova abordagem de investigação para compreender o metabolismo do DM2 e revelar potenciais alvos terapêuticos. No presente estudo, investigamos em diferentes modelos animais (humanos, ratos e camundongos) miRNAs que têm como alvo BDNF e IGF1 em tecido muscular esquelético com condições fisiológicas de DM2. As análises foram realizadas utilizando ferramentas de bioinformática e bancos de dados para predição de miRNA, homologia molecular, validação experimental de interações, expressão na condição fisiológica estudada e interação em rede. Os resultados mostraram três candidatos a miRNAs para IGF1 (miR-29a, miR-29b e miR-29c) e um para BDNF (miR-206). As avaliações experimentais e a busca pela expressão no músculo esquelético de indivíduos com DM2 confirmaram a interação prevista entre miRNA-mRNA para miR-29b e miR-206 através de modelos humanos, ratos e camundongos. Essa interação foi reafirmada em múltiplas análises de rede. Em conclusão, nossos resultados mostram a relação de regulação entre miR-29b e miR-206 com os genes investigados, em diversos tecidos, sugerindo um padrão de inibição. Contudo, esses dados mostram um grande número de possíveis processos fisiológicos de interação para perspectivas biotecnológicas.

Abstract microRNAs (miRNAs) are recognized as diabetes mellitus type 2 (T2DM) biomarkers useful for disease metabolism comprehension and have great potential as therapeutics targets. BDNF and IGF1 increased expression are highly involved in the benefits of insulin and glucose paths, however, they are down-regulated in insulin resistance conditions, while their expression increase is correlated to the improvement of glucose and insulin metabolism. Studies suggest the microRNA regulation of these genes in several different contexts, providing a novel investigation approach for comprehending T2DM metabolism and revealing potential therapeutic targets. In the present study, we investigate in different animal models (human, rat, and mouse) miRNAs that target BDNF and IGF1 in skeletal muscle tissue with T2DM physiological conditions. Bioinformatics tools and databases were used to miRNA prediction, molecular homology, experimental validation of interactions, expression in the studied physiological condition, and network interaction. The findings showed three miRNAs candidates for IGF1(miR-29a, miR-29b, and miR-29c) and one for BDNF (miR-206). The experimental evaluations and the search for the expression in skeletal muscle from T2DM subjects confirmed the predicted interaction between miRNA-mRNA for miR-29b and miR-206 through human, rat, and mouse models. This interaction was reaffirmed in multiple network analyses. In conclusion, our results show the regulation relationship between miR-29b and miR-206 with the investigated genes, in several tissues, suggesting an inhibition pattern. Nevertheless, these data show a large number of possible interaction physiological processes, for future biotechnological prospects.

Resumo Insetos galhadores são abundantes na natureza, encontrados em muitos ecossistemas globalmente, com espécies atacando plantas de importância econômica. Os efeitos de herbívoros de alimentação livre na abundância de insetos galhadores em árvores de Caryocar brasiliense (Caryocaraceae) no Cerrado brasileiro (Savana) foram estudados. A porcentagem de desfolha e o número de ácaros fitófagos ou de Hemiptera fitófagos correlacionaram-se, negativamente, com a percentagem de folhas galhadas e de adultos do parasitoide Eurytoma sp. (Hymenoptera: Eurytomidae), respectivamente. Porcentagem de folhas galhadas e o número de Eurytoma sp. adultos e ácaros fitófagos correlacionaram-se, positivamente, com o de aranhas. Os números de ácaros e fitófagos Hemiptera correlacionaram-se, positivamente, com os de joaninhas e Sycophila sp. (Hymenoptera: Eurytomidae), respectivamente. O número de adultos de Ablerus magistretti Blanchard (Hymenoptera: Aphelinidae) correlacionou-se, negativamente, com Sycophila sp. O número de Agistemus sp. (Acari: Stigmaeidae) correlacionou-se, negativa e positivamente, com os de joaninhas e ácaros fitófagos, respectivamente. Herbívoros de alimentação livre afetaram a presença de insetos galhadores (Hymenoptera) em árvores de C. brasiliense, competindo por alimento e espaço. O mesmo foi observado entre dois parasitoides de Eurytoma sp., o que pode reduzir o controle biológico natural dessa praga.

Abstract Galling insects are abundant in nature, found in many ecosystems globally, with species attacking plants of economic importance. We studied the effects of free-feeding organisms on the abundance of galling insects on Caryocar brasiliense (Caryocaraceae) trees in the Brazilian Cerrado (Savanna). Percentage of defoliation and the number of phytophagous mites or number of phytophagous Hemiptera correlated negatively with percentage of galled leaves and the parasitoid Eurytoma sp. (Hymenoptera: Eurytomidae) adults, respectively. Percentage of galled leaves and the numbers of Eurytoma sp. adults and phytophagous mites correlated positively with spiders. Numbers of mites and Hemiptera phytophagous correlated positively with those of lady beetles and Sycophila sp. (Hymenoptera: Eurytomidae), respectively. The number of Ablerus magistretti Blanchard (Hymenoptera: Aphelinidae) adults correlated negatively with Sycophila sp. The number of Agistemus sp. (Acari: Stigmaeidae) correlated, negatively and positively, with those of lady beetles and phytophagous mites, respectively. Free-feeding herbivores affected the presence of galling insects (Hymenoptera) on C. brasiliense trees, competing for food and space. The same was observed between two parasitoids of Eurytoma sp. galling insect, which can reduce the natural biological control of this pest.

Resumo Em uma escala global o Sorghum bicolor (L.) é uma das culturas mais importantes, ocupando o quinto lugar entre todos os cereais. É cultivada na África, Ásia, Oceania e Américas, onde serve como fonte de alimento e ração para humanos e animais, respectivamente. No entanto, a produção é limitada por vários fatores, incluindo pragas e doenças. Entre as pragas que atacam o sorgo, Schizaphis graminum (Rondani), comumente chamado de pulgão verde dos cereais, é a praga mais destrutiva do sorgo. O dano de S. graminum ao sorgo é agravado pelo déficit hídrico que favorece sua ocorrência. Informações limitadas sobre a distribuição espacial da praga e seus inimigos naturais impedem o desenvolvimento de estratégias de manejo ecologicamente corretas. Portanto, o objetivo desta pesquisa foi determinar a distribuição espaço-temporal de S. graminum e seu inimigo natural Coccinella septempunctata (L.) durante a fase vegetativa e reprodutiva da cultura por meio de análise geoestatística. A distribuição espaço-temporal de S. graminum foi influenciada pelo estágio de desenvolvimento do sorgo, paisagem circundante e presença de seu principal predador C. septempunctata. Além disso, a abundância de C. septempunctata foi influenciada pela densidade de S. graminum. Os resultados deste estudo são necessários para o desenvolvimento de estratégias sustentáveis de manejo de pragas contra S. graminum.

Abstract At the global level, Sorghum bicolor (L.), is one of the most important crops, which ranks fifth among all cereals. It is cultivated in Africa, Asia, Oceania and the Americas, where it serves as a source of food and feed for humans and animals, respectively. However, production is constrained by several factors including pests and diseases. Among the pests that are known to attack Sorghum, Schizaphis graminum (Rondani), commonly called the green cereal aphid, is the most destructive pest of sorghum. S. graminum damage to sorghum is worsen by water deficit which favors its occurrence. Limited information on the spatial distribution of the pest and its natural enemies impedes the development of ecologically friendly management strategies. Therefore, the objective of this research was to determine the spatiotemporal distribution of S. graminum and its natural enemy Coccinella septempunctata (L.) during the vegetative and reproductive stage of the crop using geostatistical analysis. The spatiotemporal distribution of S. graminum was influenced by Sorghum development stage, surrounding landscape, and presence of its main predator C. septempunctata. Moreover, the abundance of C. septempunctata was influenced by the density of S. graminum. The findings from this study are required for developing sustainable pest management strategies against S. graminum.

Resumo Para mitigar os efeitos deletérios do estresse salino, tem se utilizado substâncias capazes de atuar como atenuantes e/ou indutoras de tolerância ao estresse, viabilizando o uso de águas salinas e contribuindo para desenvolvimento da agricultura irrigada. Neste contexto, objetivou-se com presente estudo, avaliar o efeito da pulverização foliar com peróxido de hidrogênio como atenuante do estresse salino sobre a morfofisiologia da gravioleira. O estudo foi conduzido sob condições de casa de vegetação, em Campina Grande - PB, utilizando-se o delineamento de blocos casualizados, no arranjo fatorial 4 × 4, cujos tratamentos resultaram da combinação de quatro níveis de condutividade elétrica da água de irrigação - CEa (0,8 – controle; 1,6; 2,4 e 3,2 dS m-1) e quatro concentrações de peróxido de hidrogênio - H2O2 (0; 10; 20 e 30 µM), com três repetições. A aplicação foliar de peróxido de hidrogênio na concentração de 10 µM aumentou o crescimento, a síntese de clorofila e o teor relativo de água nas folhas e consequentemente reduziu o déficit de saturação hídrica foliar da gravioleira irrigada com CEa de até 1,6 dS m-1. A concentração de peroxido de hidrogênio de 30 µM intensificou o estresse salino sobre o extravasamento de eletrólitos no limbo foliar e os pigmentos fotossintéticos da gravioleira, aos 270 dias após o transplantio.

Abstract To mitigate the deleterious effects of salt stress, substances capable of acting as mitigators and/or inducers of tolerance to stress have been used, enabling the use of saline waters and contributing to the development of irrigated agriculture. In this context, the aim of the present study was to evaluate the effect of foliar spraying with hydrogen peroxide as an attenuator of salt stress effects on soursop morphophysiology. The experiment was conducted under greenhouse conditions in Campina Grande - PB, Brazil, using a randomized block design, in a 4 × 4 factorial arrangement, whose treatments resulted from the combination of four levels of electrical conductivity of irrigation water - ECw (0.8 – control, 1.6, 2.4, and 3.2 dS m-1) and four concentrations of hydrogen peroxide - H2O2 (0, 10, 20, and 30 μM), with three replicates. Foliar application of hydrogen peroxide at a concentration of 10 µM increased growth, chlorophyll synthesis, and relative water content in the leaves and consequently reduced the foliar water saturation deficit of soursop irrigated with ECw up to 1.6 dS m-1. The concentration of hydrogen peroxide of 30 µM intensified the salt stress on the electrolyte leakage in the leaf blade and the photosynthetic pigments of soursop, 270 days after transplanting.

Abstract Objective In this systematic review (SR), the authors aimed to identify the possible impact of the social restriction imposed by the Coronavirus Disease-19 (COVID-19) pandemic on children/adolescents with Attention Deficit Hyperactivity Disorder (ADHD). Data sources This SR was registered on PROSPERO CRD42021255569. Eligible articles were selected from PubMed, Embase, and LILACS, according to the following characteristics: ADHD patients < 18 years old, exposed to the COVID-19 pandemic, and the outcomes, medications, relationships, sleep, media use, remote learning, and comorbidities such as depression/sadness, inattention, anxiety, and irritability/aggressiveness. Newcastle-Ottawa Scale (NOS) for cohort, cross-sectional and case-control studies was used to assess methodological quality and the risk of bias. Summary of findings Of the 222 articles identified, 27 were included, with information on 7,235 patients. Most studies (n = 22) were cross-sectional and received a mean NOS 4.63/10 followed by longitudinal (n = 4) with 3.75/8 points and case-control (n = 1), with 3/9 points. The pandemic affected patients’ access to treatment, behavior, and sleep. Difficulties in remote learning and increased use of social media were described, as well as significant and positive changes in relationships with family and peers. Conclusion Although the studies were heterogeneous, they indicated that the pandemic-related issues experienced by patients with ADHD were mostly manifested affecting their behavior and sleep patterns.

Abstract Objectives To assess the prevalence and pattern of behavioral problems in children and adolescents with atopic dermatitis (AD) and to study their associations with clinical data and severity. Methods This was a single-center, cross-sectional study of patients (6-17 years) with AD. Assessment of competencies and syndrome scale scores of behavioral problems was performed by applying the Child Behavior Checklist 6-18 (CBCL 6-18) and AD severity using the Eczema Area Severity Index (EASI) score. Results Of the 100 patients with AD, 56% were male, with a mean age of 11±3 years, and 43% had moderate/severe AD. Borderline or abnormal values were found in 75% of the patients for total social competence, 57% for internalization, 27% for externalization, and 18% for aggressive behavior. A higher prevalence of aggressive behavior (27.9% vs. 10.5%; p= 0.02) and sleep disorders (32.6% vs. 15.8%; p= 0.04) was observed in patients with moderate/severe AD than in those with mild AD. Children with current or previous use of immunosuppressants/immunobiological tests had a lower frequency of normal social competence (53% vs. 83%, p= 0.012). Regarding the critical questions, 8% responded affirmatively to suicidal ideation. Conclusion A high prevalence of behavioral problems was observed among children and adolescents with AD, with a predominance of internalizing profiles, mainly anxiety and depression. Children with moderate/severe AD have a higher prevalence of aggressive behaviors and sleep disorders. These findings highlight the importance of multidisciplinary teams, including mental health professionals, in caring for patients with AD.

Abstract: Creation, adjustments and adoption of tests and tools that help in the prediction of seed storability have been highly demanded. Therefore, this work aimed to analyze the efficiency of different artificial aging times in predicting the performance of soybean seeds after storage, using the GGE biplot method. Seeds of six genotypes were subjected to storage, under refrigerated and non-refrigerated conditions, and artificial aging, being artificially aged for periods of 0, 48, 96 and 144 hours. Seeds freshly harvested and after natural and artificial aging were subjected to germination and vigor tests. The experiments were analyzed separately, using means test, regression analysis and model identity test, and together, using the GGE biplot method. Artificial aging at a temperature of 41 °C for 96 hours has the potential to be used to predict the performance of soybean seeds after eight months of storage. The GGE biplot is a method that can be used as a tool to analyze the relationships between aging environments and visualize the ranking of genotypes regarding the performance of seeds subjected to natural and artificial aging.

ABSTRACT BACKGROUND: The High Activity Arthroplasty Score (HAAS) is a self-administered questionnaire, developed in British English, that reliably and validly measures the levels of sports activities in patients following hip and knee arthroplasty surgery. OBJECTIVE: To cross-culturally adapt the HAAS to Brazilian Portuguese language. DESIGN AND SETTING: A cross-sectional study was conducted at a public university hospital in Brazil. METHODS: The Brazilian version of the HAAS was created through a six-step process: translation, synthesis, committee review, pretesting, back-translation, and submission to developers. The translation step was conducted by two independent bilingual translators, both native speakers of Brazilian Portuguese. The back-translation was performed by an independent translator, a native speaker of British English. To ensure the questionnaire's comprehensibility, 46 volunteers (51% men; average age 34-63) participated in the pre-testing step. RESULTS: The cross-cultural adaptation process necessitated modifications to certain terms and expressions to achieve cultural equivalence with the original HAAS. CONCLUSION: The HAAS has been translated from English into Brazilian Portuguese and culturally adapted for Brazil. The validation process for HAAS-Brazil is currently underway.
