Abstract: Avaliar a flexibilidade da cadeia muscular posterior, utilizando o método proposto por Wells e Dillon, antes e após cada sess o de hidroterapia. Foi verificada a flexibilidade de três crian as com Paralisia Cerebral (PC) diparéticas, com idades entre sete a dez anos. Os valores de flexibilidade foram aferidos, utilizando o Flex metro de Wells. Houve aumento significativo da flexibilidade da cadeia muscular posterior dos pacientes após cada sess o de hidroterapia, tanto na avalia o em grupo quanto individual, assim como antes da primeira sess o de hidroterapia quando comparada com a última. O estudo sugere que a hidroterapia promove melhora da flexibilidade em rela o à cadeia muscular posterior de crian as com PC diparéticas, pelo relaxamento global e consequente diminui o dot nus muscular, quando associada a exercícios de alongamentos passivos. To evaluate the flexibility of the posterior muscle chain using the method proposed by Wells and Dillon, before and after each hydrotherapy session. The study verified the flexibility of three children with diplegic cerebral palsy (CP), aged 7 to 10. The values of flexibility were measured using the Wells’ Flexometer. There was a significant increase in the flexibility of posterior muscle chain of the patients after each session of hydrotherapy, both in the individual evaluation and in the group, as well as before the first session of hydrotherapy compared to the last. The study suggests that hydrotherapy promotes the improvement of flexibility, by relaxation of muscle tone of children with diplegic CP, in relation to the posterior muscle chain, when combined with passive stretching exercises.

Abstract: in this work, chitosan and collagen-chitosan porous scaffolds were produced by the freeze drying method and characterized as potential skin substitutes. their beneficial effects on soft tissues justify the choice of both collagen and chitosan. samples were characterized using scanning electron microscope, fourier transform infrared spectroscopy (ftir) and thermogravimetry (tg). the in vitro cytocompatibility of chitosan and collagen-chitosan scaffolds was evaluated with three different assays. phenol and titanium powder were used as positive and negative controls, respectively. scanning electron microscopy revealed the highly interconnected porous structure of the scaffolds. the addition of collagen to chitosan increased both pore diameter and porosity of the scaffolds. results of ftir and tg analysis indicate that the two polymers interact yielding a miscible blend with intermediate thermal degradation properties. the reduction of xtt ((2,3-bis[2-methyloxy-4-nitro-5-sulfophenyl]-2h-tetrazolium-5-carboxanilide) and the uptake of neutral red (nr) were not affected by the blend or by the chitosan scaffold extracts, but the blend and the titanium powder presented greater incorporation of crystal violet (cv) than phenol and chitosan alone. in conclusion, collagen-chitosan scaffolds produced by freeze-drying methods were cytocompatible and presented mixed properties of each component with intermediate thermal degradation properties.

Abstract: the aim of this work was to produce hydroxyapatite (ha) granules containing 0, 0.5, 1 and 5 mol. (%) of strontium (sr), evaluate the physico-chemical properties and also the cytotoxicity by three different parameters of cell viability (iso 10993-5, 10993-12). the physico-chemical characterization was carried out by using x-ray diffraction (xrd), fourier-transform infrared spectroscopy (ftir) and x-ray fluorescence (xrf). the xrd profile presented the main peaks of ha (jcpds 860740) and the absorption bands of ha were identified by ftir. the xrf results showed that the strontium concentration was close to the theoretical value. regarding the cytotoxicity assays, the incorporation of strontium up to 5 mol. (%) to the ha did not affected dehydrogenase activity (xtt, 2,3-bis[2-methyloxy-4-nitro-5-sulfophenyl]-2h-tetrazolium-5-carboxanilide), membrane integrity (neutral red uptake) or dna contend (incorporation of crystal violet), in relation to ha alone. in conclusion, hydroxyapatite containing from 0.5 to 5 mol. (%) of sr was successfully produced and presented no cytotoxicity.

Abstract: Pós-Larvas do camar o Litopenaeus vannamei, na fase de PL9-10 e PL25-26 foram aclimatadas à água doce (0,0 ‰), objetivando promover cultivos em regi es interioranas. Para isso, foram realizados dois experimentos conduzidos em aquários com capacidade útil de 44 litros e densidade de estocagem de 11,36 pós-larvas/L. No experimento 1, foram testadas diferentes concentra es de cal hidratada (0,018 g a 0,031 g) e 2 dietas, formuladas à base de ra o comercial para camar o e biomassa de artêmia. No experimento 2, foram testadas 5dietas com diferentes concentra es de biomassa de artêmia (0% a 100%), inseridas em ra es de peixes e camar es. No final do processo de aclimata o, a sobrevivência das póslarvas variou de 40,44% a 98,04%. Concluiu-se que pós-larvas do Litopenaeus vannamei podem ser aclimatadas à água doce e que o aumento da concentra o de cal e de artêmia na ra o melhoraram significativamente (p<0,05) os parametros zootécnicos da espécie. Litopenaeus vannamei postlarvae with 9-10 (PL9-10), 25-26 days old (PL25-26) were acclimated to freshwater (0 ppt) for the purpose of attending the inland cultures. Two experiments were conducted in 44 liter aquariums with stocking density of 11.36 postlarvae/L. In experiment 01, different concentrations of hydrated lime (0.018 g a 0.031 g) and two diets, formulated with commercial shrimp ration and artemia biomass, were tested. In experiment 02, five diets, withdifferent concentrations of artemia biomass (0 to 100%) inserted in fish and shrimp rations, were tested. At the end of the acclimatization process, the postlarvae survival varied from40.44 to 98.04%. Results showed that Litopenaeus vannamei postlarvae can be acclimated to freshwater. Also, the increase of lime concentration and the artemia biomass in the ration improved (p<0.05) the zootechnic parameters of the species in a significant way.

Abstract: Ormosia arborea is a tree species planted in urban areas and used to restore degraded areas. Its seeds are dormant and propagation is difficult. This study compares different dormancy breaking methods and physiological seed quality and seedling production. The seeds were germinated in sand in the laboratory of the Universidade Estadual de Santa Cruz, Ilhéus, Bahia, Brazil. The following dormancy breaking treatments were applied: control (intact seeds), 100°C water immersion; boiling water immersion followed by 24 hours of soaking; scarification with number 100 and number 50 sandpaper opposite from root emergence; sulfuric acid immersion for 1 hour, 50, 45, and 30 minutes. Seed immersion in 100°C and boiling water did not break the dormancy. The study species showed a greater vigor of seedling when its seeds were submitted to treatments associated with tegument rupturing by sandpaper or sulfuric acid. On the other hand, seed scarification with sulfuric acid for 1 hour, 50, 45, and 30 minutes or sandpaper favored seed germination and vigor. 1. Introduction Ormosia arborea (Vell.) Harms belongs to the Leguminosae family. It is a 15–20?m tall tree, with a 50–70?cm diameter trunk. It is used in urban tree planting and the restoration of degraded areas because of its leafy canopy [1]. The seeds are dormant due to a hard seed coat that impedes water absorption. Although this is an efficient mechanism that guarantees the survival and perpetuation of the species, it is also a factor that limits propagation. It is difficult to find information on techniques to accelerate seed germination for the majority of tropical forest species. This information is needed for the cultivation of these species by nurseries and farmers, to restore degraded areas and maintain sufficient genetic diversity. Dormancy is a relatively important characteristic in the preservation of cultivated species seeds and especially important to maintain seed viability [2]. It is also one of the greatest obstacles for the germplasm conservation of forest species, which frequently produce dormant seeds. The impermeable properties of the legume seed coat to water or gases and the mechanical restraint of the embryo are achieved by a combination of structural and/or chemical properties, which have been elucidated by anatomical and ultrastructural studies. While the seed coat can be a hindrance to uniform and rapid germination, it nonetheless performs the critical functions of regulating water uptake, providing a barrier to fungal invasion, and reducing leakage from the embryo during imbibition.

Abstract: Objectives: To compare the sociodemographic and economic profile, functional capacity, number of self-referred morbidities and level of physical activity among the elderly with and without indicative of depression. Methods: Cross-sectional and analytical study, with 980 elderly persons (250 with and 730 without indicative of depression) residing in the city of Uberaba, in the State of Minas Gerais, Brazil, between August 2012 and May 2013. We used the BOMFAQ Questionnaire, GDS 15, Katz Index, Lawton and Brody Scale and IPAQ. For data analysis, descriptive statistics and the Chi-square test (p < 0.05) were used, in the program SPSS, version 17.0. Results: In the comparison between the groups, there were significant differences regarding the female gender (p = 0.009), education (p = 0.008), individual income (p < 0.001), activities of daily living (p < 0.001), instrumental activities of daily living (p < 0.001) and number of morbidities (p < 0.001). Conclusion: The comparison of the existence or not of depressive symptoms among the elderly enables a more effective planning of public policies aimed at health promotion and adequate treatment in cases of disease already present and the subsidization of preventive strategies, using data such as risk factors and associated factors and ways to research depression.

Abstract: this cross-sectional study of 831 low-risk pregnancies compared the management of labor and delivery in a birthing center, a hospital that had previously won the "galba de araújo" award (for excellence in obstetric and neonatal care), and a standard-protocol maternity facility. the rates for use of ocytocin during labor were 27.9%, 59.5%, and 40.1%, while amniotomy was performed in 67.6%, 73.6%, and 82.2% of the women, respectively. episiotomy rates were lower in the first two facilities, which have adopted patient-centered obstetric practices (7.2% at the birthing center and 14.8% at the award-winning hospital) as compared to 54.9% at the standard maternity facility. the liberal offer of epidural anesthesia at the awarding-winning hospital resulted in a higher anesthesia rate (54.4%) as compared to the standard facility (7.7%). forceps delivery and neonatal admission rates were higher in the standard hospital, but there were no differences in mean apgar or cesarean rates. the findings suggest resistance to selective use of interventions in all three models of obstetric care, although favoring the birthing center as a strategy for controlling interventions during labor and childbirth in low-risk pregnancies, with no resulting harm to the mothers or newborns.

Abstract: Experiments were performed to determine the influence of exercise training by swimming on cardiovascular autonomic control and renal morphology in spontaneously hypertensive rats (SHR) and Wystar-Kyoto (WKY) rats. Sedentary normotensive (SN), trained normotensive (TN), sedentary hypertensive (SH), and trained hypertensive (TH) rats were included in this study. Arterial pressure (AP), heart rate (HR), means of power spectral analysis of HR (HRV) and systolic AP variability (SAPV) were recorded in baseline conditions. Following, the HR baroreflex and autonomic tonus control were assessed. At the end, all animals were euthanized and their kidneys were excised to evaluate renal damage. Resting bradycardia was observed in TH and TN rats compared with their respective sedentary animals (p < 0.05). Exercise training attenuated AP in TH vs. SH (p < 0.001). The LF component of HRV and SAPV were lower in TH than SH (p < 0.05). The LF/HF relation was lower in TH than SH and SN (p < 0.05). TN and TH rats showed a sympathetic tonus reduction in comparison to SN and SH rats (p < 0.001). The TH presented an increased vagal tonus compared to SH (p < 0.05). Exercise training improved baroreflex control of HR in TH group versus SH (p < 0.05). The TH showed a lower number of sclerotic glomeruli compared to SH (p < 0.005). The exercise training decrease the glomerular indexes in TN and TH (p < 0.05). Further analysis showed a significant correlation between sympathetic nervous activity and AP levels (p < 0.05). A positive association was also found between sympathetic nervous activity and glomerular index (p < 0.05). Therefore, the exercise training reduces AP and attenuates renal damage. In addition, the attenuation of renal injury was associated with lower sympathetic activity. These findings strongly suggest that exercise training may be a therapeutic tool for improving structure and renal function in hypertensive individuals.
