Innate Immune Cells in the Tumor Microenvironment of Liver Metastasis from Colorectal Cancer: Contribution to a Comprehensive Therapy.

Colorectal cancer (CRC) is the third most prevalent type of cancer, and liver metastasis is the most common site of metastatic development. In the tumor microenvironment (TME), various innate immune cells are known to influence cancer progression and metastasis occurrence. CD274 (PD-L1) and CD206 (MRC1) are proteins that have been associated with poor prognosis and disease progression. We conducted a study on tumoral and non-tumoral biopsies from 47 patients with CRC liver metastasis, using flow cytometry to phenotypically characterize innate immune cells. Our findings showed an increase in the expression of CD274 on classical, intermediate, and non-classical monocytes when comparing tumor with non-tumor samples. Furthermore, tumor samples with a desmoplastic growth pattern exhibited a significantly decreased percentage of CD274- and CD206-positive cells in all monocyte populations compared to non-desmoplastic samples. We found a correlation between a lower expression of CD206 or CD274 on classical, intermediate, and non-classical monocytes and increased disease-free survival, which points to a better prognosis for these patients. In conclusion, our study has identified potential new targets and biomarkers that could be incorporated into a personalized medicine approach to enhance the outcome for colorectal cancer patients.

Relação do ato de comer com o controle da doença e a qualidade de vida no diabetes mellitus tipo 1 / Relationship between eating behavior and disease control on the quality of life in type 1 diabetes mellitus

O objetivo deste estudo foi analisar a relação do ato de comer com o controle da doença e a qualidade de vida em adultos com diabetes tipo 1 (DM1). Trata-se de estudo transversal, realizado através de um questionário on-line com a versão brasileira do Diabetes Quality of Life Measure (DQOL-Brasil) e de perguntas sobre controle alimentar. Foram incluídos 103 voluntários (85,4% mulheres). Nas relações com a comida, 68,9% disseram sentir vontade de comer quando estão ansiosos, preocupados ou tensos. O escore global foi de 2,36 ± 0,75 no DQOL-Brasil, e os domínios "satisfação" e "preocupações relacionadas ao diabetes" apresentaram valores mais altos. A variável idade teve correlação negativa com o escore global do DQOL-Brasil e com os domínios "impacto", "preocupações sociais/vocacionais" e "preocupações com diabetes". Esta pesquisa demonstrou associação entre o ato de comer com o controle do DM1, o que pode prejudicar a qualidade de vida desses indivíduos.

This study aimed to analyze the relationship between eating behavior, disease control, and quality of life in adults with type 1 diabetes mellitus (DM1). This cross-sectional study was conducted using an online questionnaire based on the Brazilian version of the Diabetes Quality of Life Measure (DQOL-Brazil), comprising questions on dietary control. A total of 103 volunteers (85.4% women) were included in this study. In relation to food, 68.9% said that they felt like eating when they were anxious, worried, or tensed. The overall score was 2.36 ± 0.75 on the DQOL-Brazil, with higher scores for the domains "satisfaction" and "diabetes-related concerns." The age variable had a negative correlation with the global DQOL-Brazil score and with the domains "impact," "social/vocational concerns," and "diabetes-related concerns." This study demonstrated an association between the act of eating and DM1 control, affecting the quality of life in these individuals.

Extensive Phenotypic Characterization of T Cells Infiltrating Liver Metastasis from Colorectal Cancer: A Potential Role in Precision Medicine.

Colorectal cancer (CRC) is one of the most common cancers worldwide, with liver metastasis being its main cause of death. This study harvested fresh biological material from non-tumor and tumor tissue from 47 patients with CRC liver metastasis after surgery, followed by mechanical cellular extraction and stain-lyse-wash direct immunofluorescence technique. Here, 60 different T-cell populations were characterized by flow cytometry. Tumor samples were also subdivided according to their growth pattern into desmoplastic and non-desmoplastic. When we compared tumor versus non-tumor samples, we observed a significantly lower percentage of T-lymphocyte infiltration in the tumor in which the CD4+ T-cell density increased compared to the CD8+ T cells. T regulatory cells also increased within the tumor, even with an activated phenotype (HLA-DR+). A higher percentage of IL-17-producing cells was present in tumor samples and correlated with the metastasis size. In contrast, we also observed a significant increase in CD8+ follicular-like T cells (CD185+), suggesting a cytotoxic response to cancer cells. Additionally, most infiltrated T cells exhibit an intermediate activation phenotype (CD25+). In conclusion, our results revealed potential new targets and prognostic biomarkers that could take part in an algorithm for personalized medicine approaches improving CRC patients' outcomes.

[Maternal occupation and the duration of exclusive breastfeeding: results of a birth cohort in São Luís, in the State of Maranhão, Brazil]. / Ocupação materna e duração do aleitamento materno exclusivo: resultados de uma coorte de nascimento em São Luís, Maranhão, Brasil.

In investigations determining the duration of exclusive breastfeeding (EBF), the variable paid maternal work is mostly dichotomized into no and yes. This study analyzes possible associations between the characteristics of maternal occupation and shorter EBF duration. A cohort study was conducted in a systematic sample of births in the city of São Luís (State of Maranhão, Brazil), in 2010. The variables type of maternal occupation, numbers of days worked/week and hours worked/day, if they work while standing for most of the time, and if they lift heavy objects at work were collected with 5,166 mothers of live births. The final sample of this study had 3,268 observations. Survival analysis was used to evaluate associations between variables and EBF outcomes up to 4 months (EBF4) and EBF up to 6 months (EBF6). Not having paid work was the reference category. Adjusted Cox regressions showed that mothers with semi-specialized manual work (95% confidence interval, 95%CI: 1.02-1.58 for EBF4 and 95%CI: 1.11-1.56 for EBF6) and mothers who worked 8 or more hours daily (95%CI: 1.01-1.36 for AME4 and 95%CI: 1.11-1.41 for ESA6) more frequently discontinued EBF. Mothers with in-office occupations (95%CI: 1.07-1.46), who worked 4-5 days (95%CI: 1.01-1.36) or 6-7 days/week (95%CI: 1.09-1.40) and for 5-7 hours (95%CI: 1.03-1.43) also practiced less EBF6. Working (95%CI: 1.08-1.40) or not (95%CI: 1.03-1.34) while standing for most of the workday and lifting (95%CI: 1.07-1.56) or not (95%CI: 1.06-1.33) heavy objects at work decreased the duration of EBF6. Types of occupation and working time interfered more frequently in the duration of EBF6.

Nas investigações dos determinantes da duração do aleitamento materno exclusivo (AME), a variável trabalho materno remunerado é quase sempre dicotomizada em não e sim. Este estudo analisa possíveis associações entre características da ocupação materna e menor duração do AME.

Parental Reports of Preschoolers' Lexical and Syntactic Development: Validation of the CDI-III for European Portuguese.

This study presents the validation analysis of the European Portuguese version of the MacArthur-Bates Communicative Development Inventory III (CDI-III-PT). The CDI-III-PT is a parental report measure allowing researchers to assess expressive vocabulary and the syntactic abilities of children aged 2;6-4;0. In this study, we present a version comprising a lexical subscale which follows the Swedish adaptation and an original syntactic subscale allowing us to include language-specific structures. The reports of 739 children were collected; in addition, a standardized measure of language was also administered to a sub-sample of these children and the reports of preschool teachers were collected for another sub-sample. The results indicate a high internal consistency of the lexical and syntactic subscales. As for sociodemographic variables often found to be predictors of language development, as measured by this type of instrument, the results indicate that age and maternal education are significant predictors of the scores, and that first-born children attain higher scores in vocabulary than later born children, but no significant gender differences were found. The scores of the CDI-III-PT are positively correlated with the ones obtained in the standardized language measure, thus supporting their validity. A high agreement between the reports of parents and teachers was also found. These findings indicate that the CDI-III-PT has adequate psychometric properties and that it can be a useful tool for research and clinical practice. The age-based norms that are now provided can be used to evaluate whether a child is performing poorly compared to their peers.

Motor Compensation Strategies for Reduced Upper Limb Function Among Individuals With Duchenne Muscular Dystrophy.

The purpose of this longitudinal study was to identify and verify the compensatory motor strategies for upper limb functioning of individuals with Duchenne Muscular Dystrophy (DMD). We evaluated 32 patients diagnosed with DMD (aged 6-19 years) for cognitive and motor functioning using the Mini Mental State Examination (MMSE), Vignos Scale Jebsen Taylor Test (JTT) and Functional Skill Scale (FSS) at baseline testing and over retest intervals of six and 12 months. We used the MMSE to screen participants for capacity to engage in the research, and we analyzed absolute and percentile changes in the frequency distribution of motor strategies participants used on each JTT subtest. We also used analysis of variance with repeated measures and Bonferroni post-hoc testing of multiple comparisons to identify disease progression through FSS scores. We observed an increased frequency of compensatory motor strategies over six months. We recommend the associated use of the JTT and FSS to assess patients with DMD, since we observed worsened movement quality over a time interval of six months even while essential motor competence was maintained.

RESPONSIVENESS OF UPPER LIMB SCALES AND TRUNK CONTROL FOR THE EVOLUTION OF PATIENTS WITH DUCHENNE MUSCULAR DYSTROPHY.

OBJECTIVE: To verify the interval of responsiveness to the scales Segmental Assessment of Trunk Control (SATCo-BR), Performance of Upper Limbs (PUL), and Jebsen Taylor Test (JTT) in patients with Duchenne Muscular Dystrophy (DMD). METHODS: We assessed patients with DMD aged 6 to 19 years old and with mini-mental (MMSE) score above 10 points. The assessments were performed individually, in a single session. The upper limb function was performed by PUL and JTT, and trunk control by SATCo-BR. Assessments were repeated six and 12 months after the initial assessment. The repeated-measures analysis of variance model and Bonferroni's multiple comparison method were employed as post hoc analysis; when the ANOVA assumptions were not met, the Friedman test was applied. RESULTS: The sample consisted of 28 patients evaluated in three moments (initial, and six and 12 months after the beginning). There was a time effect for the Upper Limb function performance in the total JTT, and for the subtests, except for subtests 1 and 6, which did not show a difference between the different moments. There was also a time effect for the score of total PUL, proximal PUL, intermediate PUL, and distal PUL. In the SATCo-BR, this effect was observed between the initial and 6 months, and between the initial and 12 months. CONCLUSIONS: The JTT, PUL, and SATCo-BR scales can detect changes over time, and they showed responsiveness to detect the evolution of the disease in the 6-month interval.

Assessing Intervention Effects in Sentence Processing: Object Relatives vs. Subject Control.

Object relative clauses are harder to process than subject relative clauses. Under Grillo's (2009) Generalized Minimality framework, complexity effects of object relatives are construed as intervention effects, which result from an interaction between locality constraints on movement (Relativized Minimality) and the sentence processing system. Specifically, intervention of the subject DP in the movement dependency is expected to generate a minimality violation whenever processing limitations render the moved object underspecified, resulting in compromised comprehension. In the present study, assuming Generalized Minimality, we compared the processing of object relatives with the processing of subject control in ditransitives, which, like object relatives, instantiates a syntactic dependency across an intervening DP. This comparison is justified by the current debate on whether Control should be analyzed as movement: if control involves movement of the controller DP, as proposed by Hornstein (1999), a parallel between the processing of object relatives and subject control in ditransitives may be anticipated on the basis of intervention. In addition, we explored whether general cognitive factors contribute to complexity effects ascribed to movement across a DP. Sixty-nine adult speakers of European Portuguese read sentences and answered comprehension probes in a self-paced reading task with moving-window display, comprising four experimental conditions: Subject Relatives; Object Relatives; Subject Control; Object Control. Furthermore, participants performed four supplementary tasks, serving as measures of resistance to interference, lexical knowledge, working memory capacity and lexical access ability. The results from the reading task showed that whereas object relatives were harder to process than subject relatives, subject control was not harder to process than object control, arguing against recent movement accounts of control. Furthermore, we found that whereas object relative complexity effects assessed by response times to comprehension probes interacted with Reading Span, object relative complexity effects assessed by comprehension accuracy and reading times did not interact with any of the supplementary tasks. We discuss these results in light of Generalized Minimality and the hypothesis of modularity in syntactic processing (Caplan and Waters, 1999).

Trunk Control and Upper Limb Function of Walking and Non-walking Duchenne Muscular Dystrophy Individuals.

Aim: To verify and compare trunk control and upper limb functionality (ULs) in walking and non-walking DMD individuals, with that of individuals without dystrophinopathies.Method: Cross-sectional study, with children without dystrophinopathy (healthy control group) and in walking and non-walking DMD children evaluated by the following scales: Segmental Control Evaluation Trunk (SATCo); Performance of Upper Limb (PUL) and Jebsen-Taylor Test (JTT).Results: There was a difference between the groups in trunk control and ULs function by the PUL scale, but there was no difference between walking and the reference group in all JTT subtests; The JTT writing subtest was not different between groups. There was a strong correlation between PUL and SATCo, both had a strong correlation with disease staging and a weak correlation with JTT.Conclusions: There is relevance to the evaluation of trunk control and ULs function of walking and non-walking DMD.

Responsiveness of upper limb scales and trunk control for the evolution of patients with duchenne muscular dystrophy / Responsividade de escalas de membro superior e controle de tronco na evolução de pacientes com distrofia muscular de duchenne

ABSTRACT Objective: To verify the interval of responsiveness to the scales Segmental Assessment of Trunk Control (SATCo-BR), Performance of Upper Limbs (PUL), and Jebsen Taylor Test (JTT) in patients with Duchenne Muscular Dystrophy (DMD). Methods: We assessed patients with DMD aged 6 to 19 years old and with mini-mental (MMSE) score above 10 points. The assessments were performed individually, in a single session. The upper limb function was performed by PUL and JTT, and trunk control by SATCo-BR. Assessments were repeated six and 12 months after the initial assessment. The repeated-measures analysis of variance model and Bonferroni's multiple comparison method were employed as post hoc analysis; when the ANOVA assumptions were not met, the Friedman test was applied. Results: The sample consisted of 28 patients evaluated in three moments (initial, and six and 12 months after the beginning). There was a time effect for the Upper Limb function performance in the total JTT, and for the subtests, except for subtests 1 and 6, which did not show a difference between the different moments. There was also a time effect for the score of total PUL, proximal PUL, intermediate PUL, and distal PUL. In the SATCo-BR, this effect was observed between the initial and 6 months, and between the initial and 12 months. Conclusions: The JTT, PUL, and SATCo-BR scales can detect changes over time, and they showed responsiveness to detect the evolution of the disease in the 6-month interval.

RESUMO Objetivo: Verificar o intervalo de tempo para a responsividade das escalas Segmental Assessment of Trunk Control (SATCo-BR), Performance of Upper Limb (PUL) e o Teste de Função Manual de Jebsen Taylor (TJT) em pacientes com distrofia muscular de Duchenne (DMD). Métodos: Foram avaliados pacientes com DMD nas idades entre 6 e 19 anos, e com escore do Mini Exame do Estado Mental (MEEM) a partir de 10 pontos. As avaliações foram realizadas individualmente, em uma única sessão: a função de membro superior (MS) ocorreu pela PUL e TJT; e da do controle de tronco, pela SATCo-BR. As avaliações foram repetidas após seis e 12 meses da avaliação inicial. Foi empregado o modelo de análise de variância com medidas repetidas e o método de comparações múltiplas de Bonferroni, como análise post hoc; quando os pressupostos da ANOVA não foram atendidos, foi aplicado o teste de Friedman. Resultados: A amostra foi composta por 28 pacientes avaliados em três momentos (inicial, após seis meses e após 12 meses). Houve efeito do tempo no desempenho da função Membro Superior no TJT total e nos subtestes, exceto nos subtestes 1 e 6, que não apresentaram diferença nas avaliações entre os diferentes momentos. Houve efeito do tempo para o escore da PUL total, PUL proximal, PUL intermediário e PUL distal. No SATCo-BR, esse efeito foi entre o inicial e após seis meses, e entre o inicial e após 12 meses. Conclusões: As escalas TJT, PUL e SATCo-BR são capazes de detectar alterações ao longo do tempo, e apresentam responsividade para detectar a evolução da doença em intervalo de 6 meses.

Is the orofacial antinociceptive effect of lectins intrinsically related to their specificity to monosaccharides?

Lectins are proteins of non-immunological origin that may play several biological applications, of which we can highlight the anti-inflammatory and antinociceptive activities. In this work, we evaluated the possible effect of orofacial antinociceptive activity of three plant lectins, Dioclea violacea (DVL - Man/Glc-binding), Vatairea macrocarpa (VML - Gal-binding) and PPL (Parkia platycephala - Man/Glc-binding) in adult zebrafish. Acute nociception was induced by menthol (1.2 µM), or capsaicin (4.93 µM) applied into in the upper lip (5.0 µL) of adult wild zebrafish. Zebrafish were pretreated by intraperitoneal injection (20 µL) with vehicle (Control) or lectins (0.025; 0.05 or 0.1 mg/mL) 30 min before induction. The effect of lectins on zebrafish locomotor behavior was evaluated with the open field test. Naive groups (n = 8) were included in all tests. Our results indicate that only PPL presented antinociceptive induced by capsaicin, suggesting the potential clinical application of PPL as inhibitor of orofacial nociception and that this effect may be due to the modulation of TRPV1 channel. In conclusion, lectins that exhibit affinity to the same or different carbohydrates do not necessarily have an antinociceptive effect on the orofacial nociception model, indicating that the glycan carbohydrate binding pattern may be related to the effect on nociception inhibition.

Funcionalidade de membro superior em pacientes deambuladores e não deambuladores com distrofia muscular de Duchenne / Funcionalidad de los miembros superiores en pacientes caminantes y no caminantes con distrofia muscular de Duchenne / Upper limb function in ambulatory and non-ambulatory patients with Duchenne muscular dystrophy

RESUMO Novos tratamentos propostos para os pacientes com distrofia muscular de Duchenne (DMD) têm sua eficácia avaliada por testes de membros inferiores. Contudo, os testes funcionais de membros superiores (MMSS) avaliam tanto deambuladores (D) como não deambuladores (ND). Assim, este estudo se propôs a comparar a funcionalidade de MMSS de pacientes D e ND com DMD e correlacionar o estadiamento da doença e a função de MMSS. Trata-se de um estudo transversal no qual os pacientes foram divididos em D e ND de acordo com a escala Vignos. Posteriormente, a funcionalidade dos MMSS foi avaliada pela escala performace of upper limb (PUL). Foi realizado o teste t independente, teste qui-quadrado, teste Mann-Whitney, regressão linear e teste de correlação de Spearman pelo programa SPSS, versão 22. A pesquisa foi composta de 51 pacientes, sendo 20 D e 31 ND. Houve diferença entre os grupos em relação à idade (p=0,001), ao índice de massa corporal (IMC) (p=0,016), à escolaridade (p=0,011), quanto ao escore na escala Vignos (p<0,001) e na função dos MMSS (p<0,001). Na análise de regressão linear observamos que o paciente ser D ou ND influencia na função dos MMSS em 18 pontos na escala PUL. Houve forte correlação entre o estadiamento da doença e a função de MMSS (r2=−0,769, p<0,001). A condição funcional dos MMSS depende se o paciente é D ou ND, sendo pior nos ND. Concluiu-se que a função de MMSS tem forte correlação com o estadiamento da doença.

RESUMEN Se evalúa la eficacia de los nuevos tratamientos propuestos para pacientes con distrofia muscular de Duchenne (DMD) mediante pruebas de miembros inferiores. Sin embargo, las pruebas funcionales de las extremidades superiores (MMSS) evalúan tanto a los caminantes (C) como a los no caminantes (NC). Este estudio tuvo como objetivo comparar la funcionalidad de MMSS de pacientes C y NC con DMD y correlacionar la estadificación de la enfermedad y la función de MMSS. Este es un estudio transversal en el cual se dividieron a los pacientes en C y NC, según la escala de Vignos. Posteriormente, se evaluó la funcionalidad de las extremidades superiores utilizando la escala de rendimiento de la extremidad superior (PUL). La prueba t independiente, la prueba de chi-cuadrado, la prueba de Mann-Whitney, la regresión lineal y la prueba de correlación de Spearman se realizaron utilizando el programa SPSS, versión 22. Participaron 51 pacientes, de los cuales 20 C y 31 NC. Hubo una diferencia entre los grupos con respecto a la edad (p=0,001), índice de masa corporal (IMC) (p=0,016), nivel de estudios (p=0,011), con respecto al puntaje en la escala de Vignos (p < 0,001) y la función de los MMSS (p<0,001). En el análisis de regresión lineal, observamos que ser C o NC influye en la función de las extremidades superiores en 18 puntos en la escala PUL. Hubo una fuerte correlación entre la estadificación de la enfermedad y la función de los MMSS (r2=−0.769, p<0,001). La condición funcional de los MMSS depende si el paciente es C o NC, empeorando cuando NC. Se concluyó que la función de los MMSS tiene una fuerte correlación con la estadificación de la enfermedad.

ABSTRACT New treatments proposed for patients with Duchenne muscular dystrophy (DMD) have their efficacy evaluated by lower limb tests. However, upper limb function tests evaluate both ambulatory (A) and non-ambulatory (NA) people. Thus, this work aimed to compare the upper limb function of patients A and NA with DMD and to correlate disease staging and upper limb function. This is a cross-sectional study in which patients were divided into A and NA according to the Vignos scale. Subsequently, the upper limb function was evaluated by the performance of upper limb (PUL) scale. The independent t-test, chi-square test, Mann-Whitney test, linear regression and Spearman's correlation test were performed by SPSS, version 22. The research dealt with 51 patients, 20 A and 31 NA. There were differences between the groups reference age (p=0.001), body mass index (BMI) (p=0.016), schooling (p=0.011), Vignos score (p<0.001) and upper limb function (p<0.001). The linear regression analysis showed that whether the patient was A or NA influenced the upper limb function in 18 points on the PUL scale. There was a strong correlation between disease staging and upper limb function (r2=−0.769, p<0.001). The functional condition of the upper limb depends on whether the patient is A or NA, being worse function in NA patients. We concluded that the upper limb function has a strong correlation with the staging of the disease.

The development of vocabulary and grammar: a longitudinal study of European Portuguese-speaking toddlers.

The goals of this study were to analyze the growth and stability of vocabulary, mean length of the three longest utterances (MLLUw), and sentence complexity in European Portuguese-speaking children aged 1;4-2;6, to explore differences in growth as a function of personal and family-related variables, and to investigate the inter-relationships among the three language dimensions. Fifty-one European Portuguese-speaking toddlers were longitudinally assessed at 1;4, 1;9, 2;1, and 2;6, through parent reports. Exponential growth models best described acquisition patterns during this period, but the vocabulary growth accelerated across the full age-range, whereas the growth of grammar dimensions accelerated mainly after 1;9. High variability was observed in the scores, but the toddlers' relative positions were mostly stable over time. Gender approached significance as a predictor of vocabulary growth. Maternal educational level did not predict the growth of any of the three language dimensions. Both vocabulary and MLLUw predicted sentence complexity.

Age and input effects in the acquisition of mood in Heritage Portuguese.

The present study analyzes the effect of age and amount of input in the acquisition of European Portuguese as a heritage language. An elicited production task centred on mood choice in complement clauses was applied to a group of fifty bilingual children (six- to sixteen-year-olds) who are acquiring Portuguese as a minority language in a German dominant environment. The results show a significant effect of the age at testing and the amount of input in the acquisition of the subjunctive. In general, acquisition is delayed with respect to monolinguals, even though higher convergence with the monolingual grammar is observed after twelve years of age. Results also reveal that children with more exposure to the heritage language at home show faster acquisition than children from mixed households: the eight- to nine-year-old age boundary seems relevant for those speakers with more exposure, and the twelve- to thirteen-year-old age boundary for those with less exposure.

Low level laser therapy accelerates bone healing in spinal cord injured rats.

Bone loss occurs rapidly and consistently after the occurrence of a spinal cord injury (SCI), leading to a decrease in bone mineral density (BMD) and a higher risk of fractures. In this context, the stimulatory effects of low level laser therapy (LLLT) also known as photobiomodulation (PBM) have been highlighted, mainly due to its osteogenic potential. The aim of the present study was to evaluate the effects of LLLT on bone healing using an experimental model of tibial bone defect in SCI rats. Twenty-four female Wistar rats were randomly divided into 3 groups: Sham group (SG), SCI control group (SC) and SCI laser treated group (SL). Two weeks after the induction of the SCI, animals were submitted to surgery to induce a tibial bone defect. Treatment was performed 3days a week, for 2weeks, at a single point over the area of the injury, using an 808nm laser (30mW, 100J/cm(2); 0.028cm(2), 1.7W/cm², 2.8J). The results of the histological and morphometric evaluation demonstrated that the SL group showed a larger amount of newly formed bone compared to the SC group. Moreover, a significant immunoexpression of runt-related transcription factor 2 (RUNX2) was observed in the SL group. There was no statistical difference in the biomechanical evaluation. In conclusion, the results suggest that LLLT accelerated the process of bone repair in rats with complete SCI.

In vivo potential hypoglycemic and in vitro vasorelaxant effects of Cecropia glazioviistandardized extracts

ABSTRACTThe aim of this study is to investigate the effect of Cecropia glaziovii Snethl, Urticaceae, extracts on the oral glucose tolerance curve, on glycemia in alloxan-induced diabetic rats and vasorelaxant effect after the extraction process, and to standardize the extractive solutions. The effects of the process variables and their interactions were calculated in relation to dry residue, pH, total phenolic results and chemical marker content. Furthermore, the effect of the extracts (400 mg/kg), chlorogenic (2 or 15 mg/kg) and caffeic acids (2 mg/kg) were investigated on the oral glucose tolerance curve and on glycemia in alloxan-induced diabetic rats. Oral administration of ethanol extracts 4d20 and 8d20 significantly improved glucose tolerance in the hyperglycemic rats. Chlorogenic and caffeic acids, as well as the association of the compounds were able to significantly reduce glycemia after oral gavage treatments. On the other hand, the aqueous extracts did not alter the glycemia. The aqueous extracts (8020 and 9030) and only the higher dose of chlorogenic acid presented a significant effect on serum glucose lowering in diabetic rats. Additionally, the IC50 reveals that the ethanol extracts presented more potent vasodilator effects than the aqueous extracts in aortic rings. This study shows that C. glazioviistandardized extracts exhibits antihyperglycemic action, is able to improve glucose tolerance and has a potent vascular relaxing effect. These results are probably linked to concentrations of the main phenolic compounds of the extracts.

Photobiomodulation and bone healing in diabetic rats: evaluation of bone response using a tibial defect experimental model.

Diabetes mellitus (DM) leads to a delay in bone healing. Thus, some therapeutic approaches have been used to accelerate the process of bone repair such as photobiomodulation (PBM). Therefore, the present study aimed to evaluate the effects of PBM, in different fluences, in bone repair in an experimental model of tibial bone defects in diabetic rats. Sixty-four Wistar rats were submitted to a surgical procedure to perform bone defect and distributed in four groups: diabetic control group (DCG), diabetic laser group 30 J/cm(2) (L30), diabetic laser group 60 J/cm(2) (L60), and diabetic laser group 120 J/cm(2) (L120). A 808 nm Ga-Al-As (DMC Equipment, São Carlos, SP, Brazil) laser, 100 mW; 0.028 cm(2); 3.57 W/cm(2); 30, 60, and 120 J/cm(2); 0.84, 1.68, and 3.36 J; 8, 16, and 33 s was used. Animals were euthanized 15 and 30 days after the surgery. Histological, morphometric, immunohistochemistry, and biomechanical analyses were performed. In the histological and morphometric evaluation, all laser-treated groups showed a better histological pattern and a higher amount of newly formed bone compared to DCG. An intense RUNX2 immunoexpression was observed in the laser-treated groups, 15 days after the surgery. Receptor activator of nuclear factor κ-ß ligand (RANK-L) immunohistochemistry analysis showed a significant decrease in the immunoreactivity for L30 and L120, 30 days after surgery. There was no statistical difference in the biomechanical analysis among the groups. In conclusion, PBM, in all fluences used, showed an osteogenic potential in bone healing of diabetic rats.
