Abstract: En | Text: En | PDF: En

Chagas disease, caused by the parasite Trypanosoma cruzi, occurs most commonly in Latin America. As the treatment is highly toxic and ineffective in the chronic phase of the disease, alternative treatments are needed. Through quantitative structure-activity relationship modeling (QSAR) analysis using ligand-based and structure-based virtual screening methods, we predicted the trypanocidal potential of 47 neolignans against three targets, the enzymes cruzain, trypanothione reductase, and sterol 14-alpha demethylase. A combined analysis allowed for the selection of potent inhibitors against Trypanosoma cruzi. Of these compounds, two were isolated and shown to inhibit the growth of epimastigotes at concentrations of 9.64 and 8.72 µM, and trypomastigote forms at 4.88 and 2.73 µM. Therefore, the compounds (2R, 3R)-2,3-dihydro-2 (4 methoxyphenyl)-3-methyl-5-(E)-propenylbenzofuran (46) and ottomentosa (47) may be a good option of growth inhibitors for the parasite stages and warrant additional study.

Abstract Considering the side effects in the oral cavity and dental structures of radiotherapy (RDT) for head and neck cancer, this study aimed to evaluate the effects of RDT on the root dentin concerning the obliteration of dentinal tubules, the inorganic composition of intra-radicular dentin, and the integrity of collagen fibers. Thirty human canines were selected from a biobank and randomly divided into two groups (n=15). The samples were sectioned buccolingually, and a hemisection was used for structural analysis by scanning electron microscopy (SEM) and energy-dispersive X-ray spectrometer (EDS). Low-vacuum SEM images were obtained at 2000-x magnification to observe the obliteration of the dentinal tubules. Moreover, compositional evaluation was performed using EDS. After RDT, the SEM and EDS analyses were repeated using the same methodology. RDT was applied fractionally at 2 Gy per day, 5 days per week, for 7 weeks, resulting in a total dose of 70 Gy. The collagen integrity of the irradiated and non-irradiated samples was analyzed using Masson’s trichrome and picrosirius red staining polarization microscopy. Samples subjected to RDT exhibited dentinal tubule obliteration (p < 0.001); low integrity of type I and III collagen fibers (p < 0.05); compositional reduction of calcium (p = 0.012), phosphorus (p = 0.001), and magnesium (p < 0.001); an increased Ca/P ratio (p < 0.001). RDT affects the structure of dentinal tubules, the inorganic composition of intra-radicular dentin, and the collagen fiber integrity in the root dentin, which may interfere with the effectiveness and durability of dental procedures.

Resumo Considerando os efeitos colaterais na cavidade oral e estruturas dentárias da radioterapia (RDT) para o câncer de cabeça e pescoço, este estudo teve como objetivo avaliar os efeitos da RDT sobre a dentina radicular quanto à obliteração dos túbulos dentinários, a composição inorgânica da dentina intra-radicular e a integridade das fibras colágenas. Trinta caninos humanos foram selecionados de um biobanco e divididos aleatoriamente em dois grupos (n=15). As amostras foram seccionadas no sentido vestíbulo-lingual, e uma hemissecção foi utilizada para análise estrutural por microscopia eletrônica de varredura (MEV) e espectrômetro de raios X de dispersão de energia (EDS). Imagens de MEV de baixo vácuo foram obtidas com aumento de 2500x para observar a obliteração dos túbulos dentinários. Além disso, a avaliação composicional foi realizada usando EDS. Após a RDT, as análises em MEV e EDS foram repetidas usando a mesma metodologia. A RDT foi aplicada fracionada a 2 Gy por dia, 5 dias por semana, durante 7 semanas, resultando em uma dose total de 70 Gy. A integridade do colágeno das amostras irradiadas e não irradiadas foi analisada usando microscopia de polarização de coloração com tricrômio de Masson e picrosirius red. As amostras submetidas a RDT apresentaram obliteração dos túbulos dentinários (p < 0,001); baixa integridade das fibras colágenas tipo I e III (p < 0,05); redução composicional de cálcio (p = 0,012), fósforo (p = 0,001) e magnésio (p < 0,001); e uma relação Ca/P aumentada (p < 0,001). A RDT afeta a estrutura dos túbulos dentinários, a composição inorgânica da dentina intra-radicular e a integridade das fibras colágenas na dentina radicular, o que pode interferir na eficácia e durabilidade dos procedimentos odontológicos.

Abstract: En | Text: En | PDF: En

Abstract Since the first reported case of COVID-19 in Brazil, the public and private educational system started to close. Up to November 2020, scientific discussions about the return of schooling activities have been rarely performed by the national scientific community and police-makers. The great delay of school returning in Brazil contrasts with successful international strategies of school reopening worldwide and seems counterintuitive with the reopening of non-essential activities. Here, important issues to be considered before and during school reopening are reviewed and discussed. COVID-19 testing is essential to avoid disease spreading, but high cost of individual RT-qPCRs impairs an extensive testing strategy for school returning. To reduce costs and increase the speed of diagnosis, we tested the efficiency of a pooled-sample PCR strategy in a cohort of the educational staff in the city of Macaé/RJ, finding five asymptomatic individuals (0,66%) among the 754 people tested. Thus, a polled-sample PCR testing strategy of the educational staff might prevent infection spreading in schools at a reasonable cost. We discuss how our test strategy could be coupled with internationally recognized safety rules to allow for a safe school return and how countries from different world regions are dealing with educational activities during COVID-19 pandemic.

Resumo O objetivo deste artigo é estimar o impacto da criação do Fundo Estadual de Combate à Pobreza (FECOP), em 2003, sobre indicadores de pobreza no Ceará. A aplicação empírica diferencia-se pelo uso do método de Controle Sintético Generalizado, recentemente desenvolvido por Xu (2017). Com dados em nível estadual para o período de 1981 a 2014, os resultados indicam um impacto estatisticamente significativo do FECOP sobre a redução da pobreza e extrema pobreza no Ceará a partir de 2008. Adicionalmente, realizou-se uma análise comparativa dos estados utilizados na simulação do controle sintético com o Ceará, no que diz respeito ao número e valor total de benefícios do Programa Bolsa Família. O intuito é apresentar evidências de que os efeitos encontrados não estão sendo afetados pelos repasses do programa federal.

Abstract The objective of this study is to estimate the impact of the creation of the State Fund to Combat Poverty (FECOP) in 2003 on poverty indicators in Ceará. The empirical application is distinguished by the use of the Generalized Synthetic Control method recently developed by Xu (2017). With state-level data for the period 1981 to 2014, the results indicate a statistically significant impact of FECOP on poverty and extreme poverty reduction in Ceará starting in 2008. Additionally, a comparative analysis of states composing the synthetic control for Ceará was carried out, regarding the number and total value of benefits of the Program Bolsa Família. The purpose is to present evidence that the effects found are not being affected by federal program transfers.

Resumo: O artigo descreve a história, objetivos e métodos utilizados pelas nove coortes do Consórcio RPS de Coortes de Nascimento. São identificados eixos temáticos comuns, com apresentação dos objetivos, anos de linha de base, fases de seguimento e representatividade das populações de estudo. O Consórcio inclui três coortes de nascimento de Ribeirão Preto, Estado de São Paulo (1978/1979, 1994 e 2010), quatro de Pelotas, Estado do Rio Grande do Sul (1982, 1993, 2004 e 2015) e duas de São Luís, Estado do Maranhão (1997 e 2010). As coortes provêm de três regiões do Brasil, de três estados diferentes, com importantes diferenças socioeconômicas, culturais e de infraestrutura. As coortes foram iniciadas ao nascer dos participantes, exceto a mais recente em cada município, onde as mães foram recrutadas durante a gestação. Os instrumentos para a coleta de dados foram refinados para aproximar diferentes exposições na primeira infância e a influência, a longo prazo, no processo saúde-doença. Os investigadores das nove coortes realizaram estudos perinatais e depois examinaram o capital humano, saúde mental, nutrição e sinais percursores de doenças crônicas. Um total de 17.636 nascidos vivos foram recrutados em Ribeirão Preto, 19.669 em Pelotas e 7.659 em São Luís. Nas coortes que foram iniciadas durante a gestação, foram entrevistadas 1.400 gestantes em Ribeirão Preto, 3.199 em Pelotas e 1.447 em São Luís. Foram utilizadas diferentes estratégias para reduzir as perdas de seguimento. A rede de pesquisa do Consórcio permite analisar a incidência de doenças e identificar possíveis relações causais que podem explicar os desfechos de saúde nessas populações e contribuir para o desenvolvimento de medidas públicas e políticas de saúde que estejam mais de acordo com as respectivas realidades.

Abstract: This paper describes the history, objectives and methods used by the nine Brazilian cohorts of the RPS Brazilian Birth Cohorts Consortium (Ribeirão Preto, Pelotas and São Luís) Common thematic axes are identified and the objectives, baseline periods, follow-up stages and representativity of the population studied are presented. The Consortium includes three birth cohorts from Ribeirão Preto, São Paulo State (1978/1979, 1994 and 2010), four from Pelotas, Rio Grande do Sul State (1982, 1993, 2004 and 2015), and two from São Luís, Maranhão State (1997 and 2010). The cohorts cover three regions of Brazil, from three distinct states, with marked socioeconomic, cultural and infrastructure differences. The cohorts were started at birth, except for the most recent one in each municipality, where mothers were recruited during pregnancy. The instruments for data collection have been refined in order to approach different exposures during the early phases of life and their long-term influence on the health-disease process. The investigators of the nine cohorts carried out perinatal studies and later studied human capital, mental health, nutrition and precursor signs of noncommunicable diseases. A total of 17,636 liveborns were recruited in Ribeirão Preto, 19,669 in Pelotas, and 7,659 in São Luís. In the studies starting during pregnancy, 1,400 pregnant women were interviewed in Ribeirão Preto, 3,199 in Pelotas, and 1,447 in São Luís. Different strategies were employed to reduce losses to follow-up. This research network allows the analysis of the incidence of diseases and the establishment of possible causal relations that might explain the health outcomes of these populations in order to contribute to the development of governmental actions and health policies more consistent with reality.

Resumen: El trabajo describe la historia, objetivos y métodos usados por nueve cohortes brasileñas del RPS Consorcio de Cohortes de Nacimiento. Se identificaron los ejes temáticos comunes y los objetivos, así como los periodos de referencia, la presentación del estadio de seguimiento y representatividad de la población estudiada. El consorcio incluye tres cohortes de nacimiento de Ribeirão Preto, Estado de São Paulo (1978/1979, 1994 y 2010), cuatro de Pelotas, Estado del Rio Grande do Sul (1982, 1993, 2004 y 2015), y dos de São Luís, Estado del Maranhão (1997 y 2010). Las cohortes cubren tres regiones de Brasil, de tres estados distintos, con marcadas diferencias socioeconómicas, culturales y de infraestructura. Las cohortes comenzaron con el nacimiento, excepto para la más reciente en cada municipio, donde las madres fueron reclutadas durante la gestación. Los instrumentos para la recogida de datos han sido depurados, con el fin de realizar una aproximación a diferentes exposiciones durante las fases tempranas de la vida y su influencia a largo plazo en el proceso de salud-enfermedad. Se incluyeron a los investigadores de las nueve cohortes, donde se llevaron a cabo estudios perinatales, así como los recursos humanos analizados posteriormente, al igual que la salud mental, nutrición y signos precursores de enfermedades no comunicables. Un total de 17.636 nacidos vivos fueron reclutados en Ribeirão Preto, 19.669 en Pelotas, y 7.659 en São Luís. En los estudios que comenzaron durante el embarazo, 1.400 mujeres embarazadas fueron entrevistadas en Ribeirão Preto, 3.199 en Pelotas, y 1.447 en São Luís. Se usaron diferentes estrategias para reducir pérdidas, con el fin de realizar el seguimiento. Esta red de investigación permite el análisis de la incidencia de enfermedades y el establecimiento de posibles relaciones causales que podrían explicar los resultados de salud de estas poblaciones, con el fin de contribuir al desarrollo de acciones gubernamentales y políticas de salud más consistentes con la realidad.

Resumo Clyomys laticeps é um roedor equimídeo encontrado em áreas abertas dos biomas Cerrado e Pantanal, ao longo do Brasil central e Paraguai. Essa espécie apresenta hábitos semi-fossoriais e atividade noturna. Até o momento, não existem estudos sobre seus parasitas. O objetivo deste trabalho foi descrever a comunidade de helmintos encontrados em C. laticeps, capturados no Parque Estadual da Serra de Caldas Novas, uma área de Cerrado no Brasil Central. Os indivíduos foram capturados em área de “campo sujo” entre janeiro e outubro de 2016. Os intestinos delgado e grosso de 14 roedores foram examinados quanto à presença de helmintos. Três espécies de nematoides foram encontradas: Fuellebornema almeidai, Pterygodermatites (Paucipectines) sp. e Subulura forcipata. Considerando-se as três espécies, 85,7% dos roedores apresentaram pelo menos um helminto. F. almeidai foi a espécie mais prevalente, enquanto Subulura forcipata foi a mais abundante. Este estudo é o primeiro registro da estrutura da comunidade de helmintos para C. laticeps. Como resultado, foi registrado um novo hospedeiro e o aumento da área de distribuição geográfica para o nematódeo F. almeidai e o primeiro caso de Pterygodermatites (Paucipectines) sp. infectando um roedor equimídeo. Além disso, este estudo também traz o primeiro registro de S. forcipata infectando um mamífero.

Abstract The broad-headed spiny rat, Clyomys laticeps, is an echimyid rodent found in open areas of Cerrado and Pantanal biomes in central Brazil and Paraguay. Little is known about the parasites associated with this semi-fossorial species, as no previous studies have been conducted on their helminth fauna. The aim of this study was to report the helminth community structure of C. laticeps inhabiting Serra de Caldas Novas State Park, a Cerrado area in central Brazil. Trappings were carried out in dry grasslands from January to October 2016, and the large and small intestines of 14 C. laticeps individuals were examined for the presence of helminths. Three nematode species were found: Fuellebornema almeidai, Pterygodermatites (Paucipectines) sp., and Subulura forcipata, and 85.7% of the studied species were infected with at least one of these helminths. F. almeidai was the most prevalent species among hosts, and S. forcipata was the most abundant. This study is the first report on helminth community structure in C. laticeps. We report a new host species and increase the known geographical range of F. almeidai, and provide the first record of Pterygodermatites (Paucipectines) sp. infecting echimyids. This is also the first report of S. forcipata in a mammal host.

Resumo Objetivo Apresentar o processo de adaptação transcultural do Personality Inventory for DSM-5 (PID-5) para o contexto brasileiro. Métodos A adaptação transcultural envolveu as etapas de tradução independente, versão síntese e retrotradução. A validade de conteúdo foi realizada por um comitê multidisciplinar de especialistas, com avaliação quantitativa dos índices de concordância. Por fim, o pré-teste foi conduzido com a população-alvo. Resultados Todos os estágios da adaptação transcultural foram seguidos, e na maioria das estruturas avaliadas, os valores de concordância foram satisfatórios (≥ 4.75). Grande parte das sugestões de modificações feitas pelos especialistas foram acatadas, sendo as principais relacionadas a ajustes no tempo e concordância verbal e a inclusão de letras e palavras para permitir a flexão de gênero. No pré-teste nenhuma sugestão foi apresentada e o instrumento foi considerado compreensível. Conclusão A versão brasileira do PID-5 mostrou-se adequada ao contexto brasileiro sob as perspectivas semântica, idiomática, cultural e conceitual. A versão brasileira avaliada é de uso livre, foi aprovada pelas editoras responsáveis pelos direitos autorais do instrumento e é considerada oficial. Novos estudos estão sendo conduzidos para aprimorar a busca por evidencias de validade e confiabilidade.

Abstract Objective To describe the process of cross-cultural adaptation of the Personality Inventory for DSM-5 (PID-5) to the Brazilian context. Methods Cross-cultural adaptation involved the steps of independent translation of the instrument, synthesis version, and back-translation. Analysis of content validity was conducted by a multidisciplinary expert committee and consisted of quantitative assessment of agreement indicators. The test was then applied to a target population. Results All the steps required for a cross-cultural adaptation were followed and satisfactory agreement values (≥ 4.75) were reached for most of the structures assessed. Most of the changes suggested by the experts were followed; these changes consisted primarily of adjustments to verb tense and agreement and the inclusion of letters and words to allow gender inflection. In the pre-test, no suggestions were made and the instrument was considered comprehensible. Conclusion The Brazilian version of the PID-5 was found to be adequate to the Brazilian context from semantic, idiomatic, cultural, and conceptual perspectives. The Brazilian version assessed here can be freely used, was approved by the publishers who hold the copyright on the instrument, and is considered the official version of the instrument. New studies are underway to determine the validity and reliability of the PID-5.

Abstract INTRODUCTION: HPA polymorphism has been associated with HCV presence and fibrosis progression in chronic hepatitis C. However, it is unknown if there is an association between HPA-1 polymorphism and hepatocellular carcinoma (HCC). Therefore, this study aimed to evaluate HPA-1 polymorphism in the presence of HCC. METHODS: PCR-SSP was used to perform HPA genotyping on 76 HCV-infected patients. RESULTS: There was no association between patients with and without HCC. There was significant difference in HPA-1 genotypic frequency distribution between HCC and F1/F2 fibrosis degree. CONCLUSIONS: The HPA-1a/1b polymorphism appears to be more associated with liver damage progression than with HCC presence.

Abstract AIMS The aim of the present study was to investigate the influence of resistance training (RT) and hormone replacement (HR) on MMP-2 activity, biomechanical and physical properties bone of ovariectomized (OVX) rats. METHODS Sprague-Dawley female rats were grouped into six experimental groups (n = 11 per group): sham-operated sedentary (SHAM Sed), ovariectomized sedentary (OVX Sed), sham-operated resistance training (SHAM RT), ovariectomized resistance training (OVX RT), ovariectomized sedentary hormone replacement (OVX Sed-HR), and ovariectomized resistance training hormone replacement (OVX RT-HR). HR groups received implanted silastic capsules with a 5% solution of 17β-estradiol (50 mg 17β-estradiol/ml of sunflower oil). In a 12-week RT period (27 sessions; 4-9 climbs) the animals climbed a 1.1 m vertical ladder with weights attached to their tails. Biomechanical and physical bone analyses were performed using a universal testing machine, and MMP-2 activity analysis was done by zymography. RESULTS Bone density and bone mineral content was higher in the RT and HR groups. The MMP-2 activity was higher in the RT and HR groups. The biomechanical analysis (stiffness, fracture load and maximum load) demonstrated better bone tissue quality in the RT associated with HR. CONCLUSION The RT alone as well as when it is associated with HR was efficient in increasing MMP-2 activity, biomechanical and biophysical properties bone of ovariectomized rats.

Abstract: En | Text: En | PDF: En

Background: Risk of falls increases as age advances. Complaints of impaired balance are very common in the elderly age group. Objectives: The objective of this study was to investigate whether the subjective perception of impaired balance was associated with deficits in postural control (objective analysis) in elderly community-dwelling women. Method: Static posturography was used in two groups: elderly women with (WC group) and without (NC group) complaints of impaired balance. The area, mean sway amplitude and mean speed of the center of pressure (COP) in the anterior-posterior (AP) and medial-lateral (ML) directions were analyzed in three stances: single-leg stance, double-leg stance and tandem stance, with eyes open or closed on two different surfaces: stable (firm) and unstable (foam). A digital chronometer was activated to measure the time limit (Tlimit) in the single-leg stance. Kruskal-Wallis tests followed by Mann-Whitney tests, Friedman analyses followed by post hoc Wilcoxon tests and Bonferroni corrections, and Spearman statistical tests were used in the data analysis. Differences of p<0.05 were considered statistically significant. Results: The results of posturography variables revealed no differences between groups. The timed single-leg stance test revealed a shorter Tlimit in the left single-leg stance (p=0.01) in WC group compared to NC group. A negative correlation between posturography variables and Tlimit was detected. Conclusions: Posturography did not show any differences between the groups; however, the timed single-leg stance allowed the authors to observe differences in postural control performance between elderly women with and those without complaints of impaired balance.

Introdução: A anemia falciforme (AF) é a forma mais grave da doença falciforme; apresenta formas variantes que são chamadas de haplótipos βS. Existem cinco principais haplótipos desse gene: árabe-indiano/saudi, Senegal, Benin, Bantu e Camarões. Objetivos: Caracterizar a presença dos haplótipos em pacientes com AF no Amapá. Métodos: Foram estudadas 46 amostras, todas amplificadas e analisadas pela técnica de reação em cadeia da polimerase-polimorfismo de tamanho de fragmentos de restrição (PCR-RFLP). Resultados: Bantu (61,2%) seguido de Benin (26,5%) e Senegal (12,2%). Conclusão: Foram identificados três haplótipos característicos da etnia africana, com a presença do Senegal. Em nosso estudo não encontramos a presença de haplótipos atípicos, sugerindo a concentração e semi-isolamento de grupos fundadores com pouca miscigenação.

Introduction: Sickle cell anemia (SCA) is the most severe form of sickle cell disease; it presents variants that are called haplotypes βS. There are five major haplotypes βS gene: Arab-Indian/Saudi, Senegal, Benin, Bantu, and Camaroon. Objective: Characterize the presence of haplotypes in patients with SCA in Amapá. Methods: 46 sample were studied, all samples were amplified and analyzed by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP). Results: Bantu (61.2%), followed by Benin (26.5%) and Senegal (12.2%). Conclusion: We identified three haplotypes characteristic of African ethnicity, with the presence of Senegal. In our study we found the presence of atypical haplotype, suggesting concentration and semi-isolation of the founding groups with little mixing.

Abstract: Pt En | Text: Pt En | PDF: Pt | PDF: En

A Encefalopatia hepática (HE) engloba uma variedade de sintomas neuropsiquiátricos, incluindo ansiedade e disfunção psicomotora. Embora seja uma complicação frequente da cirrose hepática, os substratos neurobiológicos responsáveis por suas manifestações clínicas são em grande parte desconhecidos. No presente estudo, ratos Wistar machos foram submetidos ao procedimento cirúrgico de ligação e secção do ducto biliar (BDL; bile-duct ligation), para indução da cirrose hepática e, no 21º dia após a cirurgia, submetidos aos testes comportamentais no labirinto em cruz elevado (LCE) e campo aberto para avaliação da ansiedade e atividade locomotora. A análise da imunorreatividade à proteína Fos (Fos-ir) foi utilizada para melhor compreender as alterações neurobiológicas presentes nos animais do grupo BDL. Foi realizada a quantificação da concentração de amônia plasmática e análise histopatológica dos fígados. Os ratos do grupo BDL mostraram diminuição significativa na porcentagem de entradas e tempo gasto nos braços abertos do LCE, caracterizando efeito ansiogênico. Estes animais também apresentaram redução significativa na Fos-ir no núcleo septal lateral e núcleo medial da amígdala. A concentração plasmática de amônia foi significativamente mais elevada que a do grupo sham e o diagnóstico de cirrose foi confirmado por análise histopatológica. Estes resultados indicam que o modelo de HE induzido por BDL induz efeito ansiogênico possivelmente relacionado à ativação de circuitos mediadores da ansiedade e à hiperamonemia.

Hepatic encephalopathy (HE) encompasses a variety of neuropsychiatric symptoms, including anxiety and psychomotor dysfunction. Although HE is a frequent complication of liver cirrhosis, the neurobiological substrates responsible for its clinical manifestations are largely unclear. In the present study, male Wistar rats were bile duct-ligated (BDL), a procedure which induces liver cirrhosis, and on the 21st day after surgery tested in the elevated plus-maze (EPM) and in an open field for anxiety and locomotor activity measurements. Analysis of Fos protein immunoreactivity (Fos-ir) was used to better understand the neurobiological alterations present in BDL animals. Plasma levels of ammonia were quantified and histopathological analysis of the livers was performed. BDL rats showed a significant decrease in the percentage of entries and time spent in the open arms of the EPM, an anxiogenic effect. These animals also presented significant decreases in Fos-ir in the lateral septal nucleus and medial amygdalar nucleus. Their ammonia plasma levels were significantly higher when compared to the sham group and the diagnosis of cirrhosis was confirmed by histopathological analysis. These results indicate that the BDL model induces anxiogenic results, possibly related to changes in the activation of anxiety-mediating circuitries and to increases in ammonia plasma levels.

Background: The effectiveness of low-level laser therapy in muscle regeneration is still not well known. Objective: To investigate the effects of laser irradiation during muscle healing. Method: For this purpose, 63 rats were distributed to 3 groups: non-irradiated control group (CG); group irradiated at 10 J/cm² (G10); and group irradiated at 50 J/cm² (G50). Each group was divided into 3 different subgroups (n=7), and on days 7, 14 and 21 post-injury the rats were sacrificed. Results: Seven days post-surgery, the CG showed destroyed zones and extensive myofibrillar degeneration. For both treated groups, the necrosis area was smaller compared to the CG. On day 14 post-injury, treated groups demonstrated better tissue organization, with newly formed muscle fibers compared to the CG. On the 21st day, the irradiated groups showed similar patterns of tissue repair, with improved muscle structure at the site of the injury, resembling uninjured muscle tissue organization. Regarding collagen deposition, the G10 showed an increase in collagen synthesis. In the last period evaluated, both treated groups showed statistically higher values in comparison with the CG. Furthermore, laser irradiation at 10 J/cm2 produced a down-regulation of cyclooxygenase 2 (Cox-2) immunoexpression on day 7 post-injury. Moreover, Cox-2 immunoexpression was decreased in both treated groups on day 14. Conclusions: Laser therapy at both fluencies stimulated muscle repair through the formation of new muscle fiber, increase in collagen synthesis, and down-regulation of Cox-2 expression.

Abstract: En | Text: En | PDF: En

BACKGROUND: Low-intensity pulsed ultrasound (LIPUS) has been shown to stimulate tissue metabolism and accelerate muscle healing. However, the optimal parameters in the use of LIPUS are still not clear. OBJECTIVE: The aim of this study was to analyze the effects of LIPUS on muscle healing in rats subjected to a cryolesion. METHOD: Twenty rats were divided into the following groups: an injured control group (CG) and an injured treated group (TG). Both groups were divided into 2 sub-groups (n=5 each) that were sacrificed 7 and 13 days post-surgery. Treatments were started 24 hours after the surgical procedure and consisted of 3 or 6 sessions. After euthanasia, the muscles were submitted to standard histological procedures. RESULTS: Qualitative analyses were based on morphological assessments of the muscle. The histopathological analysis on day 7 revealed that the muscles in the CG and the TG presented an intense inflammatory infiltrate, a large necrotic area and a disorganized tissue structure. After 13 days, both the CG and the TG had granulation tissue and newly formed fibers. The TG presented a more organized tissue structure. The quantitative analysis of collagen indicated similar findings among the groups, although the qualitative analysis revealed a better organization of collagen fibers in the TG at 13 days. The immunohistochemical analysis indicated that, at both time points, the expression of cyclooxygenase-2 was upregulated in the TG compared to the CG. CONCLUSIONS: LIPUS used as a treatment for muscle injury induced a more organized tissue structure at the site of the injury and stimulated the expression of COX-2 and the formation of new muscle fibers.
