ABSTRACT Tomato is an important economic crop due to its consumption and production worldwide. However, like other crops, it is susceptible to pathogens, being necessary agrochemicals to prevent diseases and improve the production of fruits. Among the sustainable alternatives to crop production, microbial inoculants are used as biofungicide and biostimulants for plant development. Thus, this work aimed to evaluate the biocontrol potential of seven Trichoderma spp. isolates (T1, T2, T3, T4, T15, T17, and T19) against tomato pathogens in vitro experiments, and their potential to improve tomato growth. The Trichoderma spp. antagonism was investigated against Alternaria sp. 003/09, Botrytis sp. 006/13, Fusarium sp. 007/09, and Stemphylium sp. A73. Dual culture, volatile, and diffusible compounds activity tests showed that all new Trichoderma spp. tested could reduce the mycelial growth of all tested pathogens, highlighting T15 and T17 isolates. Seed and soil inoculation revealed very contrasting results: Trichoderma sp. T17 showed a beneficial effect when inoculated in soil, reducing the percentage of yellowish leaves, and increasing dry weight and stem diameter. Inoculation of Trichoderma sp. T17 in the seed increases hypocotyl and radicle lengths, and the seed vigor index. Finally, the strains studied present the potential to be used to develop biocontrol products.

Abstract The objective of this research was to evaluate the effectiveness of using LPL (Low power laser) to reduce pain, edema, and trismus after impacted lower third molar extraction. A split-mouth randomized triple-blind clinical trial was conducted at the Federal University of Ceará. For inclusion criteria, it was necessary that the patient presented a clear indication for removal of both lower third molars, in addition to both molars being in similar positions. The third molars (38 and 48) were randomly allocated to the test group that received the LPL application protocol, and to the placebo group that received a simulation of the protocol, making a total sample of 44 surgeries. Patients in the test group used an average of 50% of the amount of analgesics that was used by the placebo group, however, there was a statistically significant difference only on days four and five. Regarding trismus, the test group presented wide mouth openings, both at 48 hours and at 7 days after surgery compared to the placebo group, but without a statistically significant difference. For edema, we noted an equilibrium between the test group and the placebo group, but no measurement obtained a statistically significant difference. The use of LPL presented better pain and trismus indicators after complex extractions. The use of LPL is thus indicated as a complementary therapy to reduce postoperative discomfort caused by complex tooth extractions.

Resumo O objetivo desta pesquisa é avaliar a eficácia do uso de LBP (laser de baixa potência) na redução da dor, edema e trismo após exodontia de terceiros molares inferiores impactados. Ensaio clínico randomizado triplo-cego do tipo boca dividida foi realizado na Universidade Federal do Ceará. Para os critérios de inclusão era necessário que o paciente apresentasse indicação clara para a remoção de ambos os terceiros molares inferiores, além da obrigatoriedade de que ambos os molares estivessem em posições semelhantes segundo Winter (1926) e Pell & Gregory (1933). Os terceiros molares (38 e 48) foram alocados aleatoriamente no grupo teste que recebeu o protocolo de aplicação dO LBP e no grupo placebo que recebeu a simulação do protocolo, perfazendo uma amostra total de 44 cirurgias. Os pacientes do grupo teste usaram em média 1/2 da quantidade de analgésicos do que os do grupo placebo, porém, apenas nos dias quatro e cinco houve diferença estatisticamente significativa. Em relação ao trismo, o grupo teste apresentou melhores indicadores tanto em 48 horas quanto em 7 dias após a cirurgia em relação ao grupo placebo, mas sem diferença estatisticamente significante. Em relação ao edema, houve medidas na amostra favoráveis ao grupo teste e medidas favoráveis ao grupo placebo, mas nenhuma das medidas obteve diferença estatisticamente significativa. O uso de LBP mostrou melhores indicadores de dor e trismo após extrações complexas. Portanto, o uso de LBP é indicado como terapia complementar para reduzir morbidades causadas por exodontias complexas.

Abstract Male breast cancer (MBC) is a rare malignancy that accounts for about 1.8% of all breast cancer cases. In contrast to the high number of the “omics” studies in breast cancer in women, only recently molecular approaches have been performed in MBC research. High-throughput proteomics based methodologies are promisor strategies to characterize the MBC proteomic signatures and their association with clinico-pathological parameters. In this study, the label-free quantification-mass spectrometry and bioinformatics approaches were applied to analyze the proteomic profiling of a MBC case using the primary breast tumor and the corresponding axillary metastatic lymph nodes and adjacent non-tumor breast tissues. The differentially expressed proteins were identified in the signaling pathways of granzyme B, sirtuins, eIF2, actin cytoskeleton, eNOS, acute phase response and calcium and were connected to the upstream regulators MYC, PI3K SMARCA4 and cancer-related chemical drugs. An additional proteomic comparative analysis was performed with a primary breast tumor of a female patient and revealed an interesting set of proteins, which were mainly involved in cancer biology. Together, our data provide a relevant data source for the MBC research that can help the therapeutic strategies for its management.

RESUMO As denominações atribuídas à libélula, – inseto de corpo comprido e fino, com quatro asas transparentes, que voa e bate a traseira na água – Questão 85 do QSL do Atlas Linguístico do Brasil, representam exemplarmente o complexo sistema variacional do léxico do português brasileiro (PB), refletindo fatos da sócio-história de cada região e, até mesmo, de cada localidade e de cada indivíduo. As variantes registradas no ALiB, publicado em 2014, com os dados das capitais, sugerem que a denominação do inseto é, em geral, de base metafórica, motivada pelo seu aspecto físico, som, movimentos e, igualmente, por associações mentais/analogias com outros semelhantes, resultando, na maioria dos casos, em signos transparentes. A fim de ratificar ou, talvez, retificar os resultados das capitais, analisamos, neste trabalho, os dados coletados no interior do país junto a 900 informantes, perfazendo o total de 225 localidades. Com o apoio desse corpus, norteadas pelos princípios teórico-metodológicos da Lexicografia e da Semântica, objetivamos: (i) verificar a dicionarização das formas obtidas; (ii) descrever as variantes quanto aos aspectos morfológicos; e (iii) analisar essas denominações sob a ótica da semântica motivacional.

ABSTRACT The names attributed to the libélula (dragonfly) – long, thin body insect, with four transparent wings, which flies and hits the rear in the water –, Question 85 of the semantic-lexical questionnaire (QSL in Portuguese) of the Linguistic Atlas of Brazil, exemplify the complex variational system of the lexicon of Brazilian Portuguese (BP), reflecting facts from the socio-history of each region and, even, each location and each individual. The variants registered in ALiB, in the state capitals, suggest that the insect’s name is, in general, of metaphorical basis, motivated by its physical aspect, sound, movements and, equally, through mental associations/analogies with similar ones, resulting, in most cases, in transparent signs. In order to ratify or, perhaps, rectify the results of the capitals, in this work, we analyzed the data collected through the country’s hinterlands from 900 informants, totaling 225 locations. With the support of this corpus, guided by the theoretical and methodological principles of Lexicography and Semantics, we aim to: (i) verify the dictionary entries of the forms obtained; (ii) describe the variants in terms of morphological aspects; and (iii) analyze these denominations from the perspective of motivational semantics.

Abstract Muscle overuse and its consequent muscle damage has no cure. Therefore, the present study aimed to investigate the regulatory role of tau-AuNPs on muscle recovery of muscle overuse model. The animals (Male Swiss mice) were randomly divided into four groups: Control (Ctr; n=6); tau-AuNPs (n=6); overuse (n=6); and overuse plus tau-AuNPs (n=6). Exercise sessions were performed for 21 consecutive days, and one exercise model was applied daily in the following sequence: low intensity, moderate intensity, and high intensity. The mice were then sacrificed. The quadriceps muscles were surgically removed for subsequent biochemical analysis (oxidative stress parameters, DNA damage markers and muscle differentiation protein). The overuse group significantly increased the oxidative stress parameters and DNA damage markers, whereas tau-AuNPs significantly decreased the oxidative stress parameters in the overuse animal model. However, there were no significant differences observed between overuse group and overuse plus tau-AuNPs administrated group in relation to DNA damage markers including DNA damage frequency and index levels when compared to control and tau-AuNPs groups. Muscle differentiation protein Myf-5 was increased in the overuse plus tau-AuNPs administration group when compared to control group. In conclusion, tau-AuNPs had significant effect on reducing oxidative stress parameters and increasing myogenic regulatory protein Myf-5 in the overuse group. However, it did not have significant effect on reducing DNA damage.

ABSTRACT Lima bean plants showing mosaic and leaf distortion symptoms, similar to those induced by viruses, were observed in several production areas in the states of Ceará and Piauí, Northeastern Brazil. The aim of this study was to identify RNA genome viruses that infect lima bean. Field research was conducted from 2017 to 2018. Fifty-five symptomatic samples were randomly collected from seven properties in five municipalities and tested by RT-PCR and DNA sequencing with specific or universal primers for two viruses and two virus groups. Four virus species were identified: cucumber mosaic virus (CMV), cowpea mild mottle virus (CPMMV), cowpea aphid-borne mosaic virus (CABMV) and cowpea severe mosaic virus (CPSMV), which had infection levels of 21.8, 52.7, 47.2, and 1.8%, respectively, as well as double and triple infections. The CMV isolates belonged to subgroup IA. The CPMMV isolates had high nucleotide identity with CPMMV isolates from Brazil, USA and Mexico. The CABMV isolates showed moderate nucleotide identity with Brazilian isolates. Only one sample was infected with CPSMV. This is the first record of CPMMV and CPSMV naturally infecting lima bean. Approaches to virus control are discussed.

Resumo O linfedema é uma condição crônica que afeta negativamente a função e a qualidade de vida. Atualmente, não existe tratamento definitivo. Todavia, algumas opções foram propostas para amenizar suas consequências. Entre elas, destaca-se a terapia complexa descongestiva (TCD), que se configura como um dos principais métodos de escolha de tratamento. Esta revisão sistemática teve por objetivo avaliar a eficácia dessa técnica no tratamento de linfedemas nos membros inferiores. Os resultados revelaram que a TCD foi eficaz na redução do volume das extremidades afetadas. No entanto, algumas questões ainda não foram elucidadas, tais como: por quanto tempo os pacientes se beneficiam com o uso da TCD? Como manter os ganhos obtidos? Diante da heterogeneidade, da insatisfatória qualidade metodológica dos trabalhos disponíveis e da inexistência de protocolo padrão para aplicação da técnica, não foi possível realizar a metanálise, o que demonstra que há muito a se avançar na investigação e na terapêutica do linfedema.

Abstract Lymphedema is a chronic condition that negatively affects function and quality of life. There is currently no definitive treatment. However, some options have been proposed to mitigate its consequences. Complex Decongestive Therapy (CDT) stands out as one of the main treatment methods of choice. This systematic review aimed to evaluate the effectiveness of this technique for treating lower extremity lymphedema. The results revealed that CDT was effective in reducing the volume of affected limbs. However, some questions have not yet been answered, such as: How long do patients benefit from using CDT? and How to maintain the gains obtained? It was not possible to perform a meta-analysis because of heterogeneity, unsatisfactory methodological quality of the available studies, and the lack of a gold-standard protocol for administration of the technique. Further studies are needed to advance lymphedema research and therapy.

ABSTRACT The excessive sun exposure, coupled with lack of sun protection represents one of the biggest risks to the occurrence of skin cancer and photoaging. Recent strategies for photoprotection have included the incorporation of natural antioxidant and anti-inflammatory compounds, into sunscreens, and the oral administration of natural antioxidant extracts. In this work, we use Brazilian red propolis extract because its antioxidant and anti-inflammatory activities. The aim of this work was to evaluate the sun protection factor and antioxidant activity of different hydroalcoholic extracts of red propolis (70% and 75%) prepared from lyophilized red propolis at room and high temperatures. The sun protection factor in vitro was determined by a spectrophotometric method developed by Mansur. The hydroalcoholic extracts of red propolis incorporated with Filter UVA-UVB 5% Gel Permulem TR-1 presented absorption in the UVB region. Also, the in vitro capacity of the hydroalcoholic extracts of red propolis to increase photoprotective activity of Filter UVA-UVB 5% Gel was evaluated. The hydroalcoholic extracts of red propolis incorporated presented higher values of sun protection factor and showed synergism in the photoprotective activity of Filter UVA-UVB 5% Gel Permulem TR-1. The antioxidant activity and sun protection factor are correlated with total phenolics content of the extracts and the hydroalcoholic extract of red propolis 75% at room temperature was choosen. The formulation developed with Filter UVA-UVB 5% Gel Permulem TR-1 with this hydroalcoholic extract of red propolis showed safe to be applied on the skin according HET-CAM test. Suggests indication of hydroalcoholic extract of red propolis (75% – room temperature) associated to photoprotective formulations for use in photoprotective products.

ABSTRACT Introduction: Intestinal parasitosis by helminths and protozoa is still today a global public health problem mainly affecting people living in conditions of social vulnerability, including rural communities. Objective: Describe human intestinal parasitosis and environmental contamination with helminths and protozoa in the Quilombola community of Quartel do Indaiá (of African descent) in the State of Minas Gerais, Brazil. Methods: A cross-sectional study was conducted of stool and soil samples by spontaneous sedimentation, and of plant samples by centrifugation sedimentation, to detect intestinal helminths and protozoa. Water samples were analyzed for total and fecal coliforms. Results: Helminths and protozoa were found in 45.5% of the people (n = 66). The species detected were Ascaris lumbricoides (18.2 %), Entamoeba coli (18.2%), Endolimax nana (18.2 %), ancylostoma (6.1 %), Iodamoeba butschlii (4.6 %), Giardia duodenalis (3%) and Trichuris trichiura (1.5 %). More than one species were present in 19.7 % of the samples. In 18 of the 39 sites sampled, the soil was contaminated with E. coli, E. nana, A. lumbricoides, I. butschlii and/or Enterobius vermicularis. Vegetables (n = 135) were contaminated in 75 samples with 7 of the 8 species analyzed. The contaminants were E. coli cysts, A. lumbricoides eggs and ancylostoma. All water samples were contaminated with total and fecal coliforms. Conclusions: The Quilombola community of Quartel do Indaiá had high levels of human infection and high environmental contamination with intestinal parasites or protozoa, probably due to lack of appropriate sanitary conditions. It is necessary to improve the access to treated water and sanitation.

RESUMEN Introducción: El parasitismo intestinal por helmintos y protozoarios todavía es un problema de salud pública mundial, que afecta sobre todo personas en condiciones de vulnerabilidad social, incluso las comunidades rurales. Objectivo: Describir la infección humana y la contaminación ambiental por parásitos/comensales intestinales en una comunidade ‘quilombola’ Quartel do Indaiá (descendentes de esclavos) del Estado de Minas Gerais, Brasil. Métodos: Estudio de corte transversal con análisis de muestras fecales y de tierra por sedimentación espontánea, y de vegetales por sedimentación con centrifugación para detección de parásitos o comensales intestinales. Se analizaron muestras de agua para detección de coliformes totales y fecales. Resultados: Se observó la ocurrencia de parásitos o comensales en 45.5 % de las personas (n = 66). Las especies detectadas fueron Ascaris lumbricoides (18,2 %), Entamoeba coli (18,2 %), Endolimax nana (18,2 %), anquilostomas (6.1 %), Iodamoeba butschlii (4,6 %), Giardia duodenalis (3 %), and Trichuris trichiura (1,5 %). Para 19,7 % de las muestras se detectaron más de una especie. El suelo estuvo contaminado en 18 de los 39 sitios muestreados, con presencia de E. coli, E. nana, A. lumbricoides, I. butschlii y/o Enterobius vermicularis. Los vegetales (n = 135) presentaron contaminación en 75 muestras de 7, entre 8 especies analizadas. Sus contaminantes fueron quistos de E. coli y huevos de A. lumbricoides y anquilostoma. Todas las muestras de agua estaban contaminadas por coliformes totales y fecales. Conclusiones: La comunidad ‘quilombola’ Quartel do Indaiá presentó alta infección humana y alta contaminación ambiental por parásitos o comensales intestinales, lo que se debe probablemente a la falta de condiciones sanitarias. Se necesita mejorar el acceso para agua tratada y estructuras de saneamiento.

RESUMO: Objetivou-se avaliar a ocorrência de pequenos ruminantes soropositivos para Brucella abortus em Sergipe, Brasil, a partir de 1.200 amostras de soro sanguíneo de ovinos e 675 de caprinos, oriundos de 101 propriedades de 25 municípios das três mesorregiões do estado, nas quais foi empregada a técnica do Antígeno Acidificado Tamponado (AAT) corado com Rosa Bengala (RB) como triagem e do 2-Mercaptoetanol (2ME) como confirmatória. Foram diagnosticados 4 animais (0,21%) soropositivos pela técnica de AAT corado com RB, 3 ovelhas (0,25%) e 1 cabra (0,15%), que posteriormente foram confirmados pelo teste de 2ME. Em todas as propriedades positivas era adotada a criação consorciada de pequenos ruminantes com bovinos, favorecendo o contato com o agente causador. A ocorrência de anticorpos anti-B. abortus em rebanhos sergipanos de pequenos ruminantes é descrita pela primeira vez, e mostra-se baixa; entretanto, é importante a identificação de animais soropositivos para que sejam descartados, devido seu potencial zoonótico.

ABSTRACT: The objective this study was to evaluate the occurrence of small ruminants seropositive for Brucella abortus in Sergipe, Brazil. Samples of sheep (1,200) and goats (675) serum blood was collected from 101 farms of 25 counties of the three mesoregions of the state. The technique of Acidified Buffered Acid stained with Rose Bengal (RB) was used and all samples confirmed a positive result using the 2-Mercaptoethanol technique. Four (0.21%) seropositive animals were diagnosed by technique AAT stained with RB, three sheep’s (0.25%) and a goat (0.15%), were confirmed by the 2ME test. In all the positive properties, the intercropping of small ruminants with cattle was adopted, favoring the contact with the agent. The prevalence of anti-B. abortus antibodies in herds of small ruminants in Sergipe is described for the first time, and is low, however, it is important to identify seropositive animals to be discarded due to their zoonotic potential.

ABSTRACT Objective: To understand the experience of people with chronic kidney disease using arteriovenous fistula. Method: Qualitative and exploratory study based on Social Phenomenology, conducted on 30 adults undergoing hemodialysis by using the fistula, interviewed in 2017. The interviews were analyzed according to the empirical-comprehensive model proposed by Amedeo Giorgi. Results: We found the categories “The changed body aesthetics”; “The perception of the other about my body”; and “The fistula as an inseparable condition for life maintenance.” Final considerations: The experience of people using fistula showed that this venous access leaves marks that change the body aesthetics, making the body imperfect. Such changes cause low self-esteem and attract the look of the other, causing embarrassment in those who have the body changed. Thus, they react by camouflaging the fistula, without which there is no life. This perception arises from the fear that works as a catalyst for self-care.

RESUMEN Objetivo: Comprender la vivencia de personas con enfermedad renal crónica en uso de fístula arteriovenosa. Método: Estudio cualitativo y exploratorio fundamentado en la fenomenología social, realizado con treinta adultos en tratamiento hemodialítico por medio de fístula, entrevistados en 2017. Los testimonios fueron analizados según el modelo empírico-comprensivo propuesto por Amedeo Giorgi. Resultados: Se desvelaron las categorías “La estética corporal alterada”; “La mirada del otro sobre mi cuerpo”; y “La fístula como condición indisociable al mantenimiento de la vida”. Consideraciones finales: La vivencia de personas en uso de fístula reveló que ese acceso venoso deja marcas que alteran la estética corporal, haciendo el cuerpo imperfecto. Esos cambios provocan baja autoestima y atraen la mirada del otro, causando constreñimiento en el que tiene el cuerpo marcado. Este, a su vez, reacciona camuflando la fístula, sin la cual no hay vida. De esa percepción surge el miedo, que actúa como catalizador para el autocuidado.

Resumo Sob a ótica da Teoria das Representações Sociais objetivou-se analisar as representações sociais acerca do uso de drogas entre os adolescentes em conflito com a lei e a existência da relação com o ato infracional. Trata-se de uma pesquisa com metodologia qualitativa com uma amostra constituída por 25 adolescentes em conflito com a lei, em cumprimento de medida socioeducativa de internação, na cidade de João Pessoa (PB). Como instrumentos foram utilizados: um questionário sociodemográfico e o desenho-estória com tema. Os dados foram analisados com o auxilio da Análise de Conteúdo Temática, proposta por Bardin. Os resultados mostram que 60% dos adolescentes pesquisados possuem idade entre 15 e 16 anos, com média de 16,3 anos (DP = 0,74). No que se refere ao ato infracional foi observado um número significativo de assalto (44%), juntamente com tentativa de homicídio e latrocínio (48%). A droga foi representada negativamente, como sendo responsável por trazer consequências relacionadas a problemas de saúde e a conflitos familiares. O crack foi citado como a droga mais destruidora e vinculada aos atos delitivos para manutenção do vício. Espera-se que os resultados encontrados possam contribuir para ampliar os conhecimentos existentes sobre a temática estudada e estimular reflexões sobre a promoção de práticas interventivas e preventivas junto aos adolescentes em medida socioeducativa.

The objective was to analyze the representations of adolescents in conflict with the law from the point of view of the Theory of Social Representations. This is a qualitative research with a sample of 25 adolescents in conflict with the law, in compliance with social educational internment measures, in the city of João Pessoa, Paraíba. A social demographic questionnaire and the “Drawings-Story with a Theme” tool were used as instruments. Data were analyzed with the aid of the Thematic Content Analysis proposed by Bardin. The results show that 60% of the adolescents surveyed were aged between 15 and 16 years, with an average of 16.3 years (DP = 0.74). Regarding the offense, a significant number of assaults (44%), as well as attempted murders, and robberies followed by murder (48%) were observed. Drugs were negatively represented as being responsible for bringing consequences related to health problems and family conflicts. Crack was cited as the most destructive drug and was linked to criminal acts that maintain addiction. We hope that the results found may contribute to broaden the existing knowledge on the subject studied and to stimulate reflections to promote intervention and preventive practices among adolescents undergoing social and educational corrections.

Abstract Introduction Digital mammography present many advantages in comparison to conventional mammography, such as high dynamic range and the post-processing of acquired images. One problem is that protocols may not be optimized, resulting in higher absorbed doses to patients. The objective of this work is to evaluate image quality and to estimate mean glandular doses (MGD) in patients submitted to mammography examinations with three digital systems and one screen-film system in Recife, Brazil. Methods To estimate the MGD, the parameters used to acquire images of 5475 patients, with ages between 40 and 64 years and compressed breasts between 2 and 9 cm, were registered. The MGD was calculated by multiplying the incident air kerma with conversion coefficients depending on the anode/filter, breast glandularity and half-value layer. The image quality evaluation of the digital systems was made using objective and subjective European criteria. Results The results showed MGDs in the range of 0.4-10.3 mGy and the higher values were observed with digital systems. It was also observed that in the digital systems the use of compression force is not adequate and the irradiation parameters are not optimized. The images failed to reproduce the pectoral muscle and the contrast-to-noise ratio was not adequate for one system, indicating the need to improve the patient’s positioning and the exposure parameters. Conclusion It can be concluded that the use of non-optimized irradiation parameters is causing the higher doses with digital systems, highlighting the insufficient compression force.

RESUMO Este trabalho baseia-se no referencial teórico da Linguística Cognitiva, adotando a Teoria dos Espaços Mentais (Fauconnier 1994, 1997, Fauconnier e Turner 2002), assim como as propostas cognitivistas de análise da dêixis de Rubba (1996) e Marmaridou (2000). O objetivo do trabalho é investigar os diferentes usos dos pronomes pessoais we (1ª pessoa do plural) e you (2ª pessoa do singular/plural) em inglês, em termos de graus de prototipicidade. Demonstra-se que os usos prototípicos desses pronomes, ancorados no Modelo Cognitivo Idealizado da dêixis, permitem a construção de usos não prototípicos, a partir de processos de mesclagem conceptual.

ABSTRACT This article uses a Cognitive Linguistics approach to meaning construction, based on Mental Spaces Theory (Fauconnier 1994, 1997, Fauconnier and Turner 2002). Drawing on cognitive proposals to the analysis of deixis by Rubba (1996) and Marmaridou (2000), our objective is to investigate the diverse uses of the personal pronouns “we” and “you” in English. We demonstrate that the prototypical uses of these pronouns, based on the Idealized Cognitive Model of deixis, permit the construction of non-prototypical uses through processes of blending.
