Abstract Objectives To better characterize the role of endoscopic cubital tunnel release in leprosy neuritis and determine whether there is an improvement in pain, sensitivity, and strength with the use of this minimally invasive technique. Methods A total of 44 endoscopic procedures for ulnar nerve decompression at the elbow were performed in patients who were previously diagnosed with leprosy neuritis. The inclusion criteria were surgical indication for ulnar nerve release and clinical treatment failure for 4 weeks in patients with cubital tunnel syndrome who had their ulnar nerve function, whether motor or sensitive, deteriorated progressively despite the treatment with prednisone 1 mg/kg/day and physiotherapy. For endoscopic release, the CTS Relief Kit (Linvatec. Largo, FL, USA) and a standard 4mm 30° arthroscope were used. Results The study included 39 patients, 29 (74.4%) males and 10 (25.6%) females. The age of the patients ranged from 12 to 64 years (33 ± 14.97). Five patients underwent bilateral release. The release demonstrated a statistically significant improvement in pain (p 0.002), in sensitivity (p< 0.001), and in strength (p< 0.001). The best results were obtained when ulnar release was performed less than 6 months after surgery indication. None of the procedures were converted from endoscopic to open. No major complications (infection, vascular injury, and nervous injury) were reported. One patient had ulnar nerve subluxation. Conclusion The endoscopic release of the ulnar nerve at the elbow in leprosy neuritis entails true and safe benefits for the patient, such as improvement in pain, sensitivity and strength.

Resumo Objetivos Os objetivos deste estudo foram caracterizar melhor o papel da liberação endoscópica do túnel cubital na neurite hansênica e determinar se há melhora da dor, sensibilidade e força com esta técnica minimamente invasiva. Métodos Um total de 44 procedimentos endoscópicos para descompressão do nervo ulnar no cotovelo foram realizados em pacientes previamente diagnosticados com neurite por hanseníase. Os critérios de inclusão foram indicação cirúrgica para liberação do nervo ulnar e insucesso do tratamento clínico por 4 semanas em pacientes com síndrome do túnel cubital que sofreram deterioração progressiva da função motora ou sensitiva do nervo ulnar apesar do tratamento de 1 mg/kg/dia de prednisona e fisioterapia. A liberação endoscópica foi realizada com CTS Relief Kit (Linvatec. Largo, FL, EUA) e um artroscópio padrão de 4 mm e 30°. Resultados O estudo incluiu 39 pacientes, sendo 29 (74,4%) homens e 10 (25,6%) mulheres. A idade dos pacientes variou de 12 a 64 anos (33 ± 14,97). Cinco pacientes foram submetidos à liberação bilateral. A liberação provocou melhora estatisticamente significativa de dor (p= 0,002), sensibilidade (p <0,001) e força (p <0,001). Os melhores resultados foram obtidos quando a liberação ulnar foi realizada em menos de 6 meses após a indicação da cirurgia. Nenhum procedimento foi convertido de endoscópico para aberto. Não foram relatadas complicações maiores (infecção, lesão vascular e lesão nervosa). Um paciente apresentou subluxação do nervo ulnar. Conclusão A liberação endoscópica do nervo ulnar no cotovelo na neurite hansênica traz benefícios verdadeiros e seguros para o paciente, como melhora da dor, sensibilidade e força.

Resumen: En | Texto: En | PDF: En

Abstract Poly(vinyl chloride) (PVC) resins constitute the third most important plastic materials available commercially, in terms of worldwide volume production, and can be manufactured through several polymerization mechanisms, including free radical, ionic and redox polymerization processes. Approximately 80% of the worldwide commercial PVC production is performed through suspension polymerization processes in batch mode, due to intrinsic problems of continuous suspension polymerization processes, such as polymer incrustation in reaction vessels, transport equipment and pipes. For this reason, the present review provides an extensive bibliometric survey, including papers and patents, on attempts to develop continuous polymerization process technologies for PVC manufacture. Particularly, the present survey characterizes the degree of maturity and the main bottlenecks of continuous PVC processes that have been frequently overlooked in the technical literature.

Resumen: En | Texto: En | PDF: En

Abstract Several phytogeographic regions (Cerrado, Pantanal, Atlantic Forest, Gran Chaco, and Chiquitano Dry Forests) converge in the state of Mato Grosso do Sul, Brazil, and influence regional biodiversity. Despite a list of birds in the state of Mato Grosso do Sul being published by Nunes et al. (2017), it is necessary to update and critically review avifauna records. In this study, we gathered the results of several records obtained from species lists and online data platforms of the 336 sites in this state over the last decades and grouped them into Main (Primary and Secondary) and Tertiary Lists. The avifauna of Mato Grosso do Sul is composed of 678 species, of which 643 (95%) have records proving their occurrence (Primary List), whereas 34 still lack documentation (Secondary List). The number of related species for Mato Grosso do Sul represents 34% of the Brazilian avifauna. Some species stand out for their unique occurrence in Mato Grosso do Sul, such as Melanerpes cactorum, Celeus lugubris, Phaethornis subochraceus, and Cantorchilus guarayanus, reflecting the influence of different phytogeographic regions of the Chaco and Chiquitano Dry Forests. Migrants represent 20% of the bird community occurring in the state, of which 93 species correspond to migrants from various regions of South America (south and west) and 40 to boreal migrants. Thirty-three species perform nomadic movements across the Pantanal Plain and other regions of the state. Thirty-one species are included in some conservation-threatened categories of global and/or national endangered species lists. Other 30 species are included in the near-threatened category at the global level and 23 at the national level. In addition, species typical of dry forests (in Serra da Bodoquena and Maciço do Urucum) and those from the Atlantic Forest in the south of the state deserve attention due to their restricted distribution and the high anthropogenic pressure on their habitat.

Resumen: En | Texto: En | PDF: En

Abstract The Program for Biodiversity Research (PPBio) is an innovative program designed to integrate all biodiversity research stakeholders. Operating since 2004, it has installed long-term ecological research sites throughout Brazil and its logic has been applied in some other southern-hemisphere countries. The program supports all aspects of research necessary to understand biodiversity and the processes that affect it. There are presently 161 sampling sites (see some of them at Supplementary Appendix), most of which use a standardized methodology that allows comparisons across biomes and through time. To date, there are about 1200 publications associated with PPBio that cover topics ranging from natural history to genetics and species distributions. Most of the field data and metadata are available through PPBio web sites or DataONE. Metadata is available for researchers that intend to explore the different faces of Brazilian biodiversity spatio-temporal variation, as well as for managers intending to improve conservation strategies. The Program also fostered, directly and indirectly, local technical capacity building, and supported the training of hundreds of undergraduate and graduate students. The main challenge is maintaining the long-term funding necessary to understand biodiversity patterns and processes under pressure from global environmental changes.

Resumen: Pt En | Texto: Pt En | PDF: Pt | PDF: En

Objetivos: Identificar clusters de controlo da asma baseados no Teste de Controlo da Asma e Rinite Alérgica (CARAT) e comparar as características dos doentes nos diferentes clusters. Métodos: Adultos e adolescentes (≥13 anos) com asma persistente foram recrutados em 29 centros no contexto de 2 estudos observacionais do projeto INSPIRERS. Foram recolhidos dados relativos a características demográficas e clínicas, adesão ao inalador, crenças sobre a medicação, sintomas de ansiedade e depressão, qualidade de vida e controlo da asma (CARAT, >24 bom controlo). Foi efetuada uma análise hierárquica de clusters usando a pontuação total do CARAT (CARAT-T).Resultados: Foram analisados 410 doentes (68% adultos), com uma idade mediana (percentil 25-percentil 75) de 28 (16-46) anos. Foram identificados três clusters [média CARAT-T(min-max)]: cluster 1 [27(24-30)], cluster 2 [19(14-23)] e cluster 3 [10(2-13)]. Os doentes no cluster 1 (34%) apresentavam melhor controlo da asma, melhor qualidade de vida, maior adesão aos inaladores e usavam um único inalador. Os doentes nos clusters 2 (50%) e 3 (16%) tinham a asma não controlada, menor adesão aos inaladores, mais sintomas de ansiedade e depressão e mais de metade reportavam pelo menos uma exacerbação no último ano. Adicionalmente, os doentes no cluster 3 eram predominantemente mulheres, tinham mais consultas médicas não agendadas, apresentavam mais sintomas de ansiedade, percebiam uma maior necessidade dos inaladores, mas também uma maior preocupação associada ao seu uso. Não se verificaram diferenças na idade, índice de massa corporal, função pulmonar, hábitos tabágicos, hospitalizações ou tempo de seguimento pelo médico especialista. Conclusões: Um método não supervisionado baseado no CARAT-T, identificou 3 clusters de doentes com diferentes características clínicas. O cluster com melhor controlo apresenta um ponto de corte semelhante ao estabelecido no estudo de validação do CARAT. Este estudo sugere ainda a existência de um ponto de corte adicional para distinguir doença mais grave. Mais investigação é necessária para validar os clusters identificados

Aims: To identify distinct asthma control clusters based on Control of Allergic Rhinitis and Asthma Test (CARAT) and to compare patients’ characteristics among these clusters. Methods: Adults and adolescents (≥13 years) with persistent asthma were recruited at 29 Portuguese hospital outpatient clinics, in the context of two observational studies of the INSPIRERS project. Demographic and clinical characteristics, adherence to inhaled medication, beliefs about inhaled medication, anxiety and depression, quality of life, and asthma control (CARAT, >24 good control) were collected. Hierarchical cluster analysis was performed using CARAT total score (CARAT-T). Results: 410 patients (68% adults), with a median (percentile 25-percentile 75) age of 28 (16-46) years, were analysed. Three clusters were identified [mean CARAT-T (min-max)]: cluster 1 [27(24-30)], cluster 2 [19(14-23)] and cluster 3 [10(2-13)]. Patients in cluster 1 (34%) were characterised by better asthma control, better quality of life, higher inhaler adherence and use of a single inhaler. Patients in clusters 2 (50%) and 3 (16%) had uncontrolled asthma, lower inhaler adherence, more symptoms of anxiety and depression and more than half had at least one exacerbation in the previous year. Furthermore, patients in cluster 3 were predominantly female, had more unscheduled medical visits and more anxiety symptoms, perceived a higher necessity of their prescribed inhalers but also higher levels of concern about taking these inhalers. There were no differences in age, body mass index, lung function, smoking status, hospital admissions or specialist physician follow-up time among the three clusters. Conclusion: An unsupervised method based on CARAT-T, identified 3 clusters of patients with distinct, clinically meaningful characteristics. The cluster with better asthma control had a cut-off similar to the established in the validation study of CARAT and an additional cut-off seems to distinguish more severe disease. Further research is necessary to validate the asthma control clusters identified.

RESUMO Introdução A obesidade é uma das principais doenças dos tempos modernos. Entretanto, a explicação da sua fisiopatologia é recente e ainda não foi totalmente esclarecida. O tecido adiposo branco sintetiza e secreta adipocinas que acometem diversas patologias relacionadas à obesidade. O aumento excessivo desse tecido resulta no aumento dos níveis de adipocinas pró-inflamatórias e na consequente diminuição de adipocinas anti-inflamatórias. Entretanto, a maioria dos estudos utiliza o treinamento de intensidade moderada, limitando o entendimento do treinamento intervalado de alta intensidade nessas proteínas. Objetivo Verificar as mais recentes informações sobre os efeitos do HIIT na melhoria do perfil das adipocinas circulantes. Métodos Foi realizada uma pesquisa nos bancos de dados PUBMED, Scielo, Lilacs, HighWire, BVS e Cochrane Database of Systematic Reviews com as seguintes palavras chaves: HIIT adipokines, HIIT leptin, HIIT adiponectin. Onze estudos foram selecionados, publicados em inglês e em português, entre os anos de 2013 e 2017. Resultados O HIIT mostrou-se eficiente para aumentar a adiponectina na população adolescente e em atletas olímpicos, mas isso depende de um bom parâmetro de prescrição e da intensidade do exercício. Entretanto, as intensidades máximas ou supramáximas se mostraram superiores às intensidades baixas e moderadas. Por sua vez, a leptina apresentou significativa diminuição em resposta ao HIIT devido à redução do tecido adiposo, demonstrando uma relação diretamente proporcional. Outras adipocinas, como a omentina-1 e a Iiterleucina-10, também responderam de forma positiva ao HIIT, resultando em um melhor estado anti-inflamatório. Conclusão O HIIT demonstrou ser um método eficiente para diminuir a inflamação decorrente da obesidade, assim como induzir uma melhora no rendimento esportivo. Entretanto, os efeitos dependem do volume de treino, intensidade e método de prescrição. Nível de evidência I; Estudo terapêutico-Investigação dos resultados do tratamento.

ABSTRACT Introduction Obesity is one of the major diseases of modern times. However, the explanation for its pathophysiology is recent and has not yet been fully elucidated. White adipose tissue synthesizes and secretes adipokines that affect several pathologies related to obesity. Excessive growth of this tissue results in increased levels of pro-inflammatory adipokines and a consequent decrease in anti-inflammatory adipokines. Nevertheless, most studies use moderate intensity training, limiting the understanding of high intensity interval training in these proteins. Objective To verify the latest information on the effects of HIIT in improving the profile of circulating adipokines. Methods A search was performed on the databases PUBMED, Lilacs, HighWire, BVS and the Cochrane Database of Systematic Reviews, with the following keywords: HIIT adipokines, HIIT leptin, HIIT adiponectin. Eleven studies were selected, published in English and Portuguese between 2013 and 2017. Results HIIT proved to be effective in increasing adiponectin in the adolescent population and in Olympic athletes, but this depended on a good prescription parameter and exercise intensity. However, maximum or supramaximal intensities were superior to low and moderate intensities. In turn, leptin presented a significant decrease in response to HIIT due to the reduction of adipose tissue, demonstrating a directly proportional relation. Other adipokines, such as omentin-1 and interleukin-10, also responded positively to HIIT, resulting in improved anti-inflammatory status. Conclusion HIIT proved to be an efficient method to reduce inflammation due to obesity, as well as inducing an improvement in sports performance. However, the effects depend on training volume, intensity and prescription method. Level of evidence I; Therapeutic study–Investigating the results of treatment.

RESUMO Neste estudo foram avaliadas a composição da dieta e a atividade alimentar de Electrophorus varii. A influência da ontogenia e da sazonalidade nestes aspectos da alimentação dos poraquês também foi examinada. Os peixes foram coletados na Bacia do rio Curiaú, Amazônia, Brasil, no período de março de 2005 a fevereiro de 2006, abrangendo os períodos chuvoso (janeiro-junho) e o seco (julho-dezembro). A dieta foi avaliada por meio da análise dos conteúdos estomacais e a dinâmica alimentar por meio do Índice de Repleção Estomacal (RI) baseado nos dados de peso do estômago. Os dados do conteúdo estomacal e do RI foram agrupados em quatro classes de tamanho em cm (40-80, 80-120, 120-160 e 160-200) e dois períodos sazonais (chuvoso e seco). A influência da ontogenia e da sazonalidade na dieta foi investigada por meio da PERMANOVA, e na dinâmica alimentar por meio da ANOVA. A análise do conteúdo estomacal mostrou que os peixes foram as presas mais consumidas pelos poraquês, especialmente Callichthyidae e Cichlidae. A composição da dieta e os valores de RI dos poraquês não foram influenciadas pela ontogenia e pela sazonalidade. Os poraquês são predadores piscívoros, independente da classe de tamanho e do período sazonal.

ABSTRACT In this study, the composition of the diet and the feeding activity of Electrophorus varii were evaluated. The influence of ontogeny and seasonality in these feeding parameters was also examined. Fish were collected in the Curiaú River Basin, Amazon, Brazil, from March 2005 to February 2006, during the rainy (January-June) and dry (July-December) seasons. Diet composition was characterized based on the analysis of stomach contents and feeding dynamics was assessed based on the Stomach Fullness Index (IR) calculated using stomach weight. Stomach content and RI data were grouped into four-cm size classes (40-80, 80-120, 120-160, and 160-200) and two seasonal periods (rainy and dry). The influence of ontogeny and seasonality in the diet was investigated through PERMANOVA, and in the food dynamics through ANOVA. The analysis of stomach contents revealed that fish were the most consumed preys by electric eels, especially Callichthyidae and Cichlidae. Diet composition and RI values of electric eels were not influenced by ontogeny and seasonality. Electric eels are fish predators, regardless of size class and seasonal period.

BACKGROUND Non-human primates contribute to the spread of the yellow fever virus (YFV) and the establishment of transmission cycles in endemic areas. OBJECTIVE To describe the severe histopathological aspects of YFV infection, 10 squirrel monkeys were infected with YFV and blood, brain, liver, kidney, spleen, heart, lung, lymph node and stomach were collected at 1-7, 10, 20 and 30 days post-infection (dpi). METHODS Histopathological analysis and detection of the genome and viral antigens and neutralising antibodies were performed by RT-PCR, immunohistochemistry and neutralisation test, respectively. FINDINGS Only one animal died from the experimental infection. The genome and viral antigens were detected in all investigated organs (1-30 dpi) and the neutralising antibodies from seven to 30 dpi. The brain contained perivascular haemorrhage (6 dpi); in the liver, midzonal haemorrhage and lytic necrosis (6 dpi) were observed. The kidney had bleeding in the Bowman’s capsule and tubular necrosis (6 dpi). Pyknotic lymphocytes were observed in the spleen (1-20 dpi), the lung had haemorrhage (2-6 dpi), in the endocardium it contained nuclear pyknosis and necrosis (2-3 dpi) and the stomach contained blood in the lumen (6 dpi). MAIN FINDINGS Squirrel monkeys reliably reproduced the responses observed in human cases of yellow fever and, therefore, constitute an excellent experimental model for studies on the pathophysiology of the disease.

Resumen: En | Texto: En | PDF: En

ABSTRACT: The incorporation of organic matter to the soil not only improves nutrient content, but also reduces the survival of Stenocarpella, the causal agent of stalk rot, Diplodia ear rot, and grey leaf spot, in maize stubble. We evaluated the effect of organic waste incorporation on Stenocarpella survival in maize stalks, the activity of suppressiveness-related enzymes, and nutrient contents. We conducted the assays in the municipalities of Lavras and Sete Lagoas, Minas Gerais State, Brazil. Maize stalks infested with Stenocarpella were kept in field conditions for three months after poultry litter, swine manure, fish hydrolysate, compost sewage sludge, and urea application. Infested stalks, without residue amendment, were kept on surface or incorporated into the soil, representing negative and positive controls. Stenocarpella concentration in stalks was assessed using qPCR expressed as cycle threshold number. Sewage sludge, buried stalks, and stalks retained on the surface showed reduction of pathogen inoculum. Swine manure and urea did not reduce the quantity of DNA. In the experiment conducted in Lavras, poultry litter stimulated β-glucosidase, urease and hydrolysis of fluorescein diacetate activities when compared to the negative control. Sewage sludge, poultry litter, and swine manure increased Ca in the soil by 44 %, 38 % and 36 %, respectively, in the experiment conducted in Lavras. Poultry litter increased Ntotal three months after application. The results indicate that organic wastes are promising in improving nutrient content, activity of hydrolysis-related enzymes, but Stenocarpella inoculum dynamics should be taken into consideration when deciding on the specific organic amendment.

Resumen: En | Texto: En | PDF: En

Abstract Introduction: Indications for cardiac devices have been increasing as well as the need for lead extractions as a result of infections, failed leads and device recalls. Powered laser sheaths, with a global trend towards the in-creasingly technological tools, meant to improve the procedure’s outcome but have economic implications. Objective: The aim of this study is to demonstrate the experience of a Bra-zilian center that uses simple manual traction in most lead removals per-formed annually, questioning the real need for expensive and technically challenging new devices. Methods: This retrospective observational study included 35 patients who had a transvenous lead extraction in the period of a year between January 1998 and October 2014 at Hospital de Messejana Dr. Carlos Alberto Studart Gomes, in Fortaleza, CE, Brazil. Data were collected through a records review. They were evaluated based on age, type of device, dwelling time, indication for removal, technique used and immediate outcomes. Results: The median dwelling time of the devices was 46.22 months. Infec-tion, lead fracture and device malfunction were the most common indica-tions. Simple traction was the method of choice, used in 88.9% of the pro-cedures. Manual traction presented high success rates, resulting in com-plete removal without complications in 90% of the cases. Conclusion: This article suggests that lead extraction by simple manual traction can still be performed effectively in countries with economic diffi-culties as a first attempt, leaving auxiliary tools for a second attempt in case of failure or contraindications to the simple manual traction technique.

Resumo: O objetivo deste trabalho foi determinar o efeito do fotoperíodo sobre o canibalismo, o crescimento e a composição corporal de juvenis de trairão (Hoplias intermedius). Um delineamento inteiramente casualizado foi empregado, com quatro fotoperíodos - 0L:24D, 6L:18D, 12L:12D e 18L:6D horas de luz (L) por horas de escuridão (D) - e quatro repetições, pelo período de 90 dias. Os parâmetros analisados foram: canibalismo, crescimento em peso e comprimento, consumo alimentar, conversão alimentar, taxa de eficiência proteica, crescimento muscular e composição corporal (umidade, lipídios, cinzas e proteína bruta). Os peixes do fotoperíodo 12L:12D apresentaram maior taxa de sobrevivência e nenhum canibalismo, bem como grande uniformidade nos valores de comprimento e massa ao final do experimento. O melhor fotoperíodo para juvenis de trairão é 12L:12D, uma vez que os peixes mostraram uniformidade de crescimento e nenhum canibalismo, enquanto peixes dos grupos 6L:18D e 18L:6D apresentaram maior diâmetro de fibras musculares brancas e maior frequência de fibras de maior diâmetro. Os peixes apresentaram menor valor de lipídios no fotoperíodo 6L:18D, e o maior valor no 12L:12D. O fotoperíodo afeta a sobrevivência e o canibalismo; quanto à composição corporal, somente os lípidos são influenciados pelo fotoperíodo.

Abstract: The objective of this work was to determine the effect of photoperiod on the cannibalism, growth, and body composition of giant trahira (Hoplias intermedius) juveniles. A completely randomized design was employed, with four photoperiods - 0L:24D, 6L:18D, 12L:12D, and 18L:6D, hours of light (L): dark (D) - and four replicates, for a period of 90 days. The analyzed parameters were: cannibalism, growth in weight and length, food consumption, feed conversion, protein efficiency rate, muscle growth, and body composition (moisture, lipid, ash, and crude protein). Fish from the 12L:12D photoperiod showed the highest survival rate and no cannibalism, as well as a great uniformity for length and mass values at the end of the experiment. The best photoperiod for giant trahira juveniles is 12L:12D, as these fish showed growth uniformity and no cannibalism, while fish from the 6L:18D and 18L:6D groups had a greater diameter of white muscle fibers and a higher frequency of greater diameter fibers. Giant trahira showed the lowest value for lipids at 6L:18D and the highest value at 12L:12D. Photoperiod affects survival and cannibalism; regarding body composition, only lipids are influenced by photoperiod.

Resumen La cochinilla Dysmicoccus brevipes (Hemiptera: Pseudococcidae) es una especie cosmopolita y polífaga que puede causar graves daños al cultivo de maní en varios países del mundo. Este estudio realizado en Campina Grande, estado Paraíba, Brasil, tuvo como objetivo determinar las pérdidas en productividad causadas por esta cochinilla en el cultivo de maní. Fue usado un diseño experimental completamente al azar con cinco tratamientos y cuatro repeticiones. Los tratamientos consistieron en cinco densidades de (ninfas y adultos) en raíces y vainas de maní de acuerdo a lo siguiente: T1 = 0 cochinillas/planta; T2 = 1-20 cochinillas/planta; T3 = 21-40 cochinillas/planta; T4 = 41-80 cochinillas/planta y T5 = más de 80 cochinillas/planta. Se observaron infestaciones en las raíces y vainas en el 84 % de las plantas muestreadas, con un número promedio de cochinillas por planta que varió entre 0 y 147,1 individuos. Cuanto mayor el número de cochinillas por planta, menor fue el peso de la vaina. La productividad media de la vaina de maní de la cultivar BR1, con las más altas y más bajas densidades de las cochinillas por planta fue de 1.695 kg ha-1 y 3.290 kg ha-1, respectivamente. Campos con alta infestación de D. brevipes arriesgan grandes pérdidas, principalmente debido a su enorme capacidad de causar daños.

Abstract The pineapple mealybug Dysmicoccus brevipes (Hemiptera: Pseudococcidae) is a cosmopolitan and polyphagous species that causes severe damage to peanut crops in many countries around the world. This work was conducted in Campina Grande, Paraíba Sate, Brazil, aiming to assess losses in productivity caused by D. brevipes in a peanut crop. A completely randomized design with five treatments and four replicates was used. Treatments consisted of five mealybug population densities (nymphs and adults) on peanut roots and pods, described as follows: T1 = 0 mealybugs per plant; T2 = 1 to 20 mealybugs per plant; T3 = 21 to 40 mealybugs per plant; T4 = 41 to 80 mealybugs per plant and T5 = more than 80 mealybugs per plant. Roots and pods infested with the pest were observed on 84 % of the peanut plants sampled, ranging from zero to 147.1 individuals per plant. The higher the number of mealybugs per plant, the lower the weight of pod. The mean pod productivities of BR1 peanut cultivars, with the highest and lowest densities of mealybugs per plant were 1,695 and 3,290 kg per ha, respectively. Fields heavily infested with D. brevipes risk significant losses due to the enormous capacity of this organism for causing damage.

Resumen: En | Texto: En | PDF: En

Abstract Carbon Fiber Reinforced Polymer (CFRP) cables, due to their outstanding performance in terms of specific stiffness and strength, are usually found in civil construction applications and, more recently, in the Oil & Gas sector. However, experimental data and theoretical solutions for these cables are very limited. On the contrary, several theoretical and numerical approaches are available for isotropic cables (metallic wire ropes), some of them with severe simplifications, nonetheless showing good agreement with experimental data. In this study, experimental tensile results for 1×7 CRFP cables were compared to a simplified analytical model (assumed transversally isotropic) and to a 3D finite element model incorporating the experimental uncertainty in important input parameters: longitudinal elastic modulus, Poisson’s ratio, static friction coefficient and ultimate tensile strain. The average experimental breaking load of the cable was 190.25 kN (coefficient of variation of 1.74%) and the agreement with the numerical model predictions were good, with an average-value deviation of –1.15%, which is lower than the experimental variations. The simplified analytical model yielded a discrepancy above 10%, indicating that it needs further refinement although much less time consuming than the numerical model. These conclusions were corroborated by statistical analyses (i.e. Kruskal–Wallis and Mann-Whitney).

RESUMO: Leishmaniose visceral (LV) é causada pelo protozoário Leishmania infantum . A transmissão deste parasito para hospedeiros é principalmente vetorial. No entanto, rotas alternativas de infecção têm sido investigadas, especialmente em áreas onde o vetor biológico está ausente. O período exato de infecção e se a transmissão in utero ocorre ainda não está totalmente elucidada. Este estudo demonstra uma evidência molecular da transmissão vertical de L. infantum de uma cadela prenhe para o embrião. As amostras (vulva, vagina, cérvix, corpo do útero, corno do útero e ovários) de uma fêmea naturalmente infectada por L. infantum e de seu embrião foram analisados molecularmente por meio de qPCR e cPCR, seguido de sequenciamento de DNA. A estimativa da idade gestacional foi de 23±1 dia. Na qPCR, a presença de DNA de L. infantum foi detectado em todas as amostras (n=7) analisadas, incluindo o embrião. No entanto, na PCR convencional, apenas quatro amostras (vagina, cérvix, corpo do útero e embrião) foram positivas. Este estudo demonstrou que a transmissão de L. infantum de uma cadela prenhe para o embrião pode ocorrer nos primeiros dias de prenhez. Em conclusão, de acordo com o conhecimento dos autores, este é o primeiro relatório evidenciando infecção de embrião canino por L. infantum.

ABSTRACT: Visceral leishmaniasis (VL) is caused by the protozoon Leishmania infantum . Transmission of this parasite to hosts occurs mainly through the bite of infected sand flies. However, alternative infection routes have been hypothesized, especially in areas where the biological vector is absent. The exact time of infection and whether in utero transmission occurs have still not been fully elucidated. This report demonstrates molecular evidence of vertical transmission of L. infantum from a pregnant dog to the embryo. Samples (e.g. vulva, vagina, cervix, uterine body, uterine horn and ovaries) from a female naturally infected by L. infantum and from her embryo were molecularly analyzed by means of qPCR and cPCR followed by DNA sequencing. The gestational age was estimated to be 23±1 day. Through qPCR, the presence of L. infantum DNA was detected in all the samples analyzed (n=7), including the embryo, conversely through cPCR, only four samples (vagina, cervix, uterine body and embryo) were positive. This study demonstrated that transmission of L. infantum from a pregnant dog to the embryo might occur in the early days of pregnancy. In conclusion, this is the first report showing L. infantum infecting a canine embryo.
