The effects of transcutaneous low-level laser therapy on the skin healing process: an experimental model.

Abstract: We aim to evaluate the action of transcutaneous laser in the initial wound healing process. The use of low-level laser therapy (LLLT) has proven to be effective on inflammatory modulation and wound healing. The trial was performed on five groups of rats, through a dorsal incision. All groups received treatment on auricular artery. Groups 1 and 3 were treated with transcutaneous LLLT over a period of 15 min. Groups 2 and 4 received one and two inactive laser applications (placebo), respectively. Group 5 was the control one. Blood samples were collected 2 h after the last application of LLLT so that cytokine levels could be measured by ELISA. Tissue fragments were harvested for morphometric, histomorphometric, and RT-qPCR analyses. The morphometric analysis revealed a greater decrease in the wounded area in G1 when compared with G2, whereas in G3, the improvement in the area was greater when compared with G4. Finally, the histomorphometric analysis showed that G1 was the group closer to G5 in terms of collagen fiber count. G2 and G4 had higher amounts of collagen fibers than G5 while G3 had a lower quantity. The use of the transcutaneous LLLT in the current study influenced the wound healing process.

Combined aerobic and resistance exercise training attenuates cardiac dysfunctions in a model of diabetes and menopause.

Abstract: The study aimed at evaluating the effects of combined aerobic and resistance exercise training on cardiac morphometry and function, oxidative stress and inflammatory parameters in diabetic ovariectomized rats For this, female Wistar rats (10 weeks-old) were divided into 4 groups (n = 8): euglycemic (E), diabetic (streptozotocin, 50 mg/kg, iv) (D), diabetic ovariectomized (DO) and trained diabetic ovariectomized (TDO) The combined exercise training was performed on a treadmill and in a ladder adapted to rats (8 weeks, at 40–60% of maximal capacity) The left ventricle (LV) morphometry and function were evaluated by echocardiography Oxidative stress and inflammatory markers were measured on ventricles tissue The sedentary diabetic animals (D and DO) showed impaired systolic and diastolic functions, as well as increased cardiac overload, evaluated by myocardial performance index (MPI- D: 032 ± 005; DO: 039 ± 013 vs E: 025 ± 007), in relation to E group Systolic and MPI dysfunctions were exacerbated in DO when compared to D group The DO group presented higher protein oxidation and TNF-α/IL-10 ratio than D groups Glutathione redox ratio (GSH/GSSG) and IL-10 were decreased in both D and DO groups when compared to E group Exercise training improved exercise capacity, systolic and diastolic functions and MPI (018±011) The TDO group showed reduced protein oxidation and TNF-α/IL-10 ratio and increased GSH/GSSG and IL-10 in relation to the DO group These results showed that combined exercise training was able to attenuate the cardiac dysfunctions, probably by reducing inflammation and oxidative stress in an experimental model of diabetes and menopause

Trajetoria e perspectivas da educação estatistica no brasil, 2010-2014: um olhar a partir do gt-12 trajectory and prospects of statistical education in brazil, 2010-2014: a view from gt-12

Abstract: Este trabalho investigou a producao cientifica em Educacao Estatistica nos ultimos cinco anos dos pesquisadores do GT-12 da SBEM. Foi feita uma analise documental da producao apresentada em seus curriculos Lattes: dissertacoes e teses, livros e capitulos de livro, artigos completos em periodicos e em eventos cientificos no periodo de 2010 a 2014. A producao cientifica foi categorizada de acordo com o conteudo, nivel de escolaridade dos participantes e enfoque metodologico. A partir dos resultados foram levantados pontos para reflexao sobre os rumos da Educacao Estatistica no Brasil, como, por exemplo, necessidade de mais pesquisas com alunos com necessidades educacionais especiais, com o apoio tecnologico e a busca de explicacoes para a tendencia verificada de diminuicao do numero de publicacoes nesta area. Palavras-chave : analise da producao cientifica; Educacao Estatistica; GT-12 da SBEM Abstract This study analyzed scientific papers about Education Statistics for the past five years, published by GT-12 researchers. It was developed a documental analysis of production reported on their curriculum in the Lattes Platform: dissertations and theses, books and chapters and publication of full papers in journals and at national and international scientific events in the period 2010 to 2014. The scientific production was classified according to content, school grade level of participants and methodological approach. The results allowed a reflection about the future of Statistics Education in Brazil, for instance, need for more papers enrolling students with special needs, with technological support and attempt to understand the trend of decrease in the number of papers in this area.

Evaluation of Different Conditions of Contact for Caprolactam Migration from Multilayer Polyamide Films into Food Simulants

Abstract: Caprolactam, the polyamide 6 (PA-6) monomer, can migrate during food processing. At cooking temperatures, migration is accelerated and plastic components could degrade, giving off low molecular mass compounds, which can migrate into food. In this work, caprolactam migration from multilayer films containing PA-6 for meat foodstuffs and cheese packaging was performed at contact conditions of 40°C/10 days and 100°C/30 min. The migration into water ranged from 0.89 to 1.22 mg/dm2 and 0.92 to 1.21 mg/dm2, into 3% acetic acid from 1.29 to 1.74 mg/dm2 and 1.13 to 1.62 mg/dm2 and into olive oil from 1.18 to 1.98 mg/dm2 and 0.50 to 0.80 mg/dm2 for films intended for meat foodstuffs for 10 days at 40°C and 30 min at 100°C, respectively. Among PA-6 films used for cheese, caprolactam migration into water ranged from 0.17 to 0.91 mg/dm2 and 0.74 to 1.04 mg/dm2, into 3% acetic acid from 1.15 to 1.26 mg/dm2 and 1.11 to 1.37 mg/dm2 and into olive oil from 0.23 to 0.83 mg/dm2 and 0.37 to 0.56 mg/dm2 for 10 days at 40°C and 30 min at 100°C, respectively. Caprolactam migration evaluation into water and 3% acetic acid at 100°C/30 min could replace the need to apply the test at 40°C/10 days, since similar results were obtained under both conditions. In the case of PA-6 for meat foodstuffs, caprolactam migration into olive oil was highly affected by different conditions of contact, showing values two to three times higher at 40°C/10 days than at 100°C/30 min. For cheese films, caprolactam migration into olive oil was higher at 40°C for 10 days. Copyright © 2013 John Wiley & Sons, Ltd.

Caffeine supplementation affects the immunometabolic response to concurrent training.

Abstract: The aim of the present study was to investigate the effects of caffeine (CAF) and carbohydrate (CHO) intake on strength performance and its metabolic and inflammatory responses during concurrent training. Seven active males ingested a double-placebo (P), CAF (capsule 5 mg/kg) or CHO (20% maltodextrin solution) supplementation before strength exercise. Participants performed three randomized sessions of 5,000-m high-intensity intermittent aerobic exercise at maximal intensity followed by strength exercise, performing after the P, CHO, and CAF intake. The blood samples were collected before (pre) and immediately after concurrent strength exercise (post). We found a similar number of repetitions and total volume in all supplementation groups. There was a main effect of time on glucose, lactate, and interleukin (IL)-6 (P<0.05). When compared the changes between groups (postvalues minus prevalues), there was lower glucose in CAF group when compared to CHO group (CAF= 5.0±10.4 vs. CHO=27.8±20 vs. P=15.1±14, P=0.031) and higher IL-6 levels (CAF=11.9±9.2 vs. CHO=-2.4±1.7 vs. P=4.3± 11.7, P=0.017). There was significant interaction for glucose and lactate (P<0.001). In conclusion, CAF and CHO intake did not improve strength performance during concurrent strength training in active males. However, CAF affected immunometabolic responses.
