Resumo: Objetivo: Avaliar a eficácia do método Pilates na redução da dor crônica associada à escoliose não estrutural. Método: Participaram do estudo ensaio clínico controlado e aleatorizado 31 universitárias, com idade entre 18 e 25 anos, com diagnóstico de escoliose não estrutural e apresentando dor crônica na coluna vertebral. A amostra foi dividida em grupo controle (n=11) que não foi submetido a nenhuma intervenção terapêutica e grupo experimental (n=20) que participou do programa de mecanoterapia pelo método Pilates. A intervenção consistiu de vinte e quatro sessões. Os movimentos foram orientados de acordo com a convexidade da escoliose de cada indivíduo. Foi utilizado o teste de Adams, radiografia panorâmica da coluna vertebral (pré tratamento) e um questionário mediante a "Escala de dor percebida CR 10 de Borg" (pré e pós tratamento). O tratamento estatístico utilizado foi a ANOVA 2x2 de medidas repetidas, seguida do teste post hoc de Tukey. Resultados: Os resultados identificaram diminuição significativa de 66% da dor no grupo experimental (P = 0,0002). Conclusão: Pode-se verificar que o programa de exercícios utilizando-se o método Pilates para jovens com escoliose não estrutural, apresentando dor na coluna vertebral é eficaz, pois houve redução da intensidade de dor.

Reduction of the chronic pain associated to the scoliosis non structural, in university students submitted to the Pilates methodAbstract: Objective: To evaluate the effectiveness of the Pilates method in the reduction of the chronic pain associated to a non structural scoliosis. Method: 31 academical subjects participated in the clinical aleatorical controlled experiment study, under age between 18 and 25 years, with diagnosis of non structural scoliosis and presenting chronic pain in the spine. The sample was divided into: control group (n=11) that the was not submitted to any therapeutic intervention and experimental group (n=20) that participated of the mecanotherapy program for the Pilates method. The intervention consisted of twenty-four sessions. The movements were guided in agreement with the convexity of each individual's scoliosis. The test of Adams, panoramic x-ray of the spine was used (pre treatment) and a questionnaire by the "Scale of noticed pain CR 10 of Borg" (pre and post treatment). The used statistical treatment was ANOVA 2x2 of repeated measures with the test post hoc of Tukey. Results: Findings demonstrated a significant decrease of 66% of the pain for the experimental group (P = 0,0002). Conclusion: It can be observed that the exercise program using the Pilates method to young people is effective and improved the reduction of chronic pain among young subjects presenting non structural scoliosis.
IntroductionThe objective of this work was to evaluate the efficacy of placenta-derived mesenchymal stem cell (MSC) therapy in a mouse model of myocardial infarction (MI). Since MSCs can be obtained from two different regions of the human term placenta (chorionic plate or villi), cells obtained from both these regions were compared so that the best candidate for cell therapy could be selected.MethodsFor the in vitro studies, chorionic plate MSCs (cp-MSCs) and chorionic villi MSCs (cv-MSCs) were extensively characterized for their genetic stability, clonogenic and differentiation potential, gene expression, and immunophenotype. For the in vivo studies, C57Bl/6 mice were submitted to MI and, after 21 days, received weekly intramyocardial injections of cp-MSCs for 3 weeks. Cells were also stably transduced with a viral construct expressing luciferase, under the control of the murine stem cell virus (MSCV) promoter, and were used in a bioluminescence assay. The expression of genes associated with the insulin signaling pathway was analyzed in the cardiac tissue from cp-MSCs and placebo groups.ResultsMorphology, differentiation, immunophenotype, and proliferation were quite similar between these cells. However, cp-MSCs had a greater clonogenic potential and higher expression of genes related to cell cycle progression and genome stability. Therefore, we considered that the chorionic plate was preferable to the chorionic villi for the isolation of MSCs. Sixty days after MI, cell-treated mice had a significant increase in ejection fraction and a reduction in end-systolic volume. This improvement was not caused by a reduction in infarct size. In addition, tracking of cp-MSCs transduced with luciferase revealed that cells remained in the heart for 4 days after the first injection but that the survival period was reduced after the second and third injections. Quantitative reverse transcription-polymerase chain reaction revealed similar expression of genes involved in the insulin signaling pathway when comparing cell-treated and placebo groups.ConclusionsImprovement of cardiac function by cp-MSCs did not require permanent engraftment and was not mediated by the insulin signaling pathway.Electronic supplementary materialThe online version of this article (doi:10.1186/scrt490) contains supplementary material, which is available to authorized users.
These data clearly shows that G-CSF treatment was unable to prevent cardiac remodeling or to improve cardiovascular function in a rat model of acute myocardial infarction, by permanent LAD ligation, despite bone marrow stem cell mobilization.
O objetivo deste estudo foi analisar o efeito do método da Reeducação Postural Global (RPG) em escolares com diagnóstico de escoliose torácica não estrutural (ETNE). Os escolares com indicativo de ETNE ao exame postural e teste de Adams negativo foram encaminhados ao exame radiográfico para comprovação diagnóstica. Foram selecionados 20 participantes (11 meninos e 9 meninas, com 10±3 anos), divididos randomicamente em dois grupos homogêneos: o que realizou o RPG (GRPG) durante 12 semanas com duração de 25 a 30 minutos cada sessão, de acordo com o que aguentou permanecer na postura; e o grupo controle (GC), sem intervenção. Após três meses, os dois grupos repetiram a avaliação postural e o exame radiográfico. Para avaliação das estatísticas, foi utilizada análise de variância (ANOVA) univariada, com medidas repetidas, seguida do Post Hoc de Tukey para identificar as possíveis diferenças intra e intergrupos. O valor de α foi de 0,05. O GRPG apresentou redução significativa no ângulo de Cobb na comparação intragrupo (Δ%=-35,100; p=0,009), mas o GC não (Δ%=9,520; p=0,789). Pode-se concluir que escolares submetidos ao método da RPG apresentaram melhora do quadro de escoliose torácica não estrutural.
BackgroundChagas disease, caused by the protozoan Trypanosoma cruzi (T.cruzi), is a complex disease endemic in Central and South America. It has been gathering interest due to increases in non-vectorial forms of transmission, especially in developed countries. The objective of this work was to investigate if adipose tissue-derived mesenchymal stromal cells (ASC) can alter the course of the disease and attenuate pathology in a mouse model of chagasic cardiomyopathy.Methodology/Principal FindingsASC were injected intraperitoneally at 3 days post-infection (dpi). Tracking by bioluminescence showed that cells remained in the abdominal cavity for up to 9 days after injection and most of them migrated to the abdominal or subcutaneous fat, an early parasite reservoir. ASC injection resulted in a significant reduction in blood parasitemia, which was followed by a decrease in cardiac tissue inflammation, parasitism and fibrosis at 30 dpi. At the same time point, analyses of cytokine release in cells isolated from the heart and exposed to T. cruzi antigens indicated an anti-inflammatory response in ASC-treated animals. In parallel, splenocytes exposed to the same antigens produced a pro-inflammatory response, which is important for the control of parasite replication, in placebo and ASC-treated groups. However, splenocytes from the ASC group released higher levels of IL-10. At 60 dpi, magnetic resonance imaging revealed that right ventricular (RV) dilation was prevented in ASC-treated mice.Conclusions/SignificanceIn conclusion, the injection of ASC early after T. cruzi infection prevents RV remodeling through the modulation of immune responses. Lymphoid organ response to the parasite promoted the control of parasite burden, while the heart, a target organ of Chagas disease, was protected from damage due to an improved control of inflammation in ASC-treated mice.
