Abstract Fiber Reinforced Soils (FRS) are mixtures of discrete fibers with the soil to create a composite with improved mechanical properties compared to unreinforced material that depends on several soil and fiber properties. Therefore, comparative studies are needed to better understand their influence on FRS mechanical response. This paper analyzes the results of a comprehensive triaxial testing program performed on specimens of two different sands at the same relative density focusing on how the grain size distribution affects the composite behavior in terms of shear strength and dilatancy. It is shown that the grain size curve's uniformity coefficient (Cu) is one of the critical variables controlling FRS's dilatancy. Dune sand specimens (Cu = 1.79) presented dilatancy even for confining stresses as high as 300 kPa. The shear gains due to reinforcement were controlled by fiber length (L) and percentage (Pf), and size and shape of soil particles. River sand specimens with L = 51 mm and 1% fiber addition (dry mass) presented increments of 47.7 kPa in soil cohesion and a 5.2o increase in the soil friction angle compared to unreinforced material.

Abstract Aim: To assess the postural control performance of football 5-a-side (FFS) players, comparing them with sighted players. Methods: Eight FFS players and 7 sighted futsal players were included. Postural control tests included feet together stance (FTS) and single-leg stance (SLS) tasks, performed on rigid and foam surfaces. Sighted players performed the tests with open (EO) and closed (EC) eyes. Area of displacement (Area) and average velocity (Vavg) were calculated from the center of pressure time-series coordinates. Results: On both surfaces conditions, a significant difference between visually impaired football 5-a-side players and sighted EO players was observed during FTS (higher Vavg for visually impaired football 5-a-side players; p < 0.04) and SLS (higher Area and Vavg for visually impaired football 5-a-side players; p < 0.01). No differences between visually impaired football 5-a-side players and sighted EC players were found. Differences between sighted EO vs. sighted EC were observed during FTS on the foam surface, and in SLS on both surface conditions (p < 0.03). Conclusion: FFS players’ postural control performance is similar to sighted players with EC but worse than sighted players with EO, suggesting their postural control performance can be simply explained in terms of visual restriction.

RESUMO A atrazina é um herbicida sintético comumente utilizado no controle de ervas gramíneas daninhas e folhagens em lavouras, e é um dos principais contaminantes dos solos e dos ecossistemas aquáticos. Muitos métodos têm sido sugeridos para remover herbicidas da água potável. Contudo, esses métodos são custosos, muitos têm problemas de desempenho, produzem diversos subprodutos intermediários tóxicos, prejudiciais e perigosos. Entretanto, a atrazina é susceptível à degradação por microrganismos presentes na água, no sedimento e no esgoto. Considerando esses aspectos, o objetivo principal do estudo foi investigar a biodegradação e a filtração por meio de filtros de carvão com atividade biológica (CAB) para remoção da atrazina, e sua identificação filogenética associada a esses microrganismos. Os resultados demonstraram que a atrazina foi degradada por microrganismos presentes no biofilme, com remoção superior a 89% nos filtros CAB. Os microrganismos encontrados integram-se ao grupo das bactérias, composto dos gêneros Acinetobacter,Bacillus, Exiguobacterium e Pseudomonas. Este estudo nos permite inferir sobre a capacidade de biodegradação da atrazina por bactérias presentes nos filtros CAB, a capacidade de remover herbicidas por meio desse sistema de filtros e a possível utilização dessa tecnologia como alternativa para o controle e a remoção dessa substância no tratamento de água.

ABSTRACT Atrazine is a synthetic herbicide commonly used to control weeds and foliage in crops, and is a major contaminants of soil and water ecosystems. Many methods have been suggested to remove herbicides from drinking water. However, these methods are very costly, many have performance problems, produce a lot of toxic intermediates which are very harmful and dangerous. However, atrazine is susceptible to degradation by microorganism present in water, sediment, and sewage effluents. Considering these aspects, the main objective of the study was to investigate the biodegradation and filtration for using biological activated carbon (BAC) filters to remove atrazine, and their phylogenetic identification associated with these microorganisms. The results showed that atrazine was biodegraded by microorganism present in the biofilm, with removal over 80% in BAC filters. The microorganisms found integrate to the group of bacteria, composed by the genera Acinetobacter, Bacillus, Exiguobacterium, and Pseudomonas. This study allows us to infer the ability to biodegrade atrazine by bacteria present in BAC filters and capacity to remove herbicides by BAC filters, and the possible use of this technology as an alternative for the control and removal of this substance in water treatment.

RESUMO O objetivo do estudo foi descrever o controle postural na posição ereta semiestática de atletas com diferentes graus de deficiência visual e verificar se existem diferenças de acordo com a modalidade esportiva praticada. Participaram deste estudo seccional 22 atletas com perda total da visão (classificação funcional B1) e 17 com baixa visão (classificação funcional B2 e B3) das modalidades judô (n=17), goalball (n=12) e futebol de cinco (n=10). O controle postural foi investigado utilizando uma plataforma de força, sendo calculadas a área da elipse de 95% de intervalo de confiança (mm2) e a velocidade média de deslocamento (mm/s). A tarefa postural foi realizada com os pés unidos e olhos fechados e vendados. Atletas com perda total da visão apresentaram menores valores para área de oscilação (p=0,02) em relação aos atletas com baixa visão. Na comparação quanto à modalidade esportiva, foi possível observar que os atletas de goalball oscilaram menos e apresentaram menor velocidade de deslocamento que os atletas de judô. Em paralelo, os jogadores de futebol de cinco foram aqueles que apresentaram melhor controle postural. As diferenças encontradas no controle postural de atletas com deficiência visual parecem estar associadas ao grau de perda visual e às especificidades das modalidades esportivas.

ABSTRACT The aim of this study was to describe postural control in athletes with different degrees of visual impairment in erect semi-static position and verify whether it differs with sport modalities. Twenty-two athletes with total loss of vision (functional classification B1) and 17 with partial loss of vision (functional classification B2 and B3) were included in this cross-sectional study. Their sport modalities were judo (n = 17), goalball (n = 12) and five-a-side football (n=10). Postural control was investigated on a force platform with athletes in bipedal stance with eyes closed and blindfolded. The elliptical area of 95% confidence interval (mm2) and the mean displacement velocity (mm/s) were calculated. Athletes with total loss of vision presented smaller oscillation area values (p = 0.02) when compared to athletes with partial loss of vision. Considering sport modality, five-a-side athletes were found to present the best postural control. Moreover, goalball athletes oscillated less and presented a lower mean displacement velocity in relation to judoists. The differences found in postural control in visually impaired athletes seem to be associated with the degree of loss of vision and specificities of each sport modality.

OBJECTIVES: To evaluate pulmonary function in the first and third trimesters of pregnancy and analyze the influence of parity and smoking on spirometry parameters. METHODS: This longitudinal prospective study included a cohort of 120 pregnant women. The inclusion criteria were as follows: singleton pregnancy, gestational age less than 13.86 weeks, and no preexisting maternal diseases. The exclusion criteria were as follows: change of address, abortion, and inadequate spirometry testing. ClinicalTrials.gov: NCT02807038. RESULTS: A decrease in values of forced vital capacity and forced expiratory volume were noted in the first second from the first to third trimester. In the first and third trimesters, multiparous women demonstrated lower absolute forced vital capacity and forced expiratory volume values in the first second compared with nulliparous women (p<0.0001 and p=0.001, respectively). Multiparous women demonstrated reduced forced expiratory flow in 25% to 75% of the maneuver compared with nulliparous women in the first (p=0.005) and third (p=0.031) trimesters. The absolute values of forced expiratory flow in 25% to 75%, forced expiratory volume in the first second and predicted peak expiratory flow values in the third trimester were higher in smokers compared with nonsmokers (p=0.042, p=0.039, p=0.024, and p=0.021, respectively). CONCLUSION: There was a significant reduction in forced vital capacity and forced expiratory volume values in the first second during pregnancy. Parity and smoking significantly influence spirometric variables.

ABSTRACT In spite of advances in colorectal cancer treatments, approximately 1.4 million new global cases are estimated for 2015. In this sense, Brazilian plant diversity offers a multiplicity of essential oils as prospective novel anticancer compounds. This study aimed to evaluate the antiproliferative effect of the essential oils from four Lippia species in CT26.WT colon tumor cells, as a measurement of cell cycle phase distribution and microRNA expression. CT26.WT showed cell cycle arrest at G2/M phase after treatment with 100 µg/ml of Lippia alba (Mill.) N.E.Br. ex Britton & P. Wilson, Lippia sidoides Cham., and Lippia lacunosa Mart. & Schauer, Verbenaceae, essential oils and, at the same concentration, Lippia rotundifolia Cham. essential oil caused an augment of G0/G1 phase. The miRNA expression profiling shows change of expression in key oncogenic miRNAs genes after treatment. Our findings suggest growth inhibition mechanisms for all four essential oils on CT26.WT cells involving direct or indirect interference on cell cycle arrest and/or oncogenic miRNAs expression.

Abstract Prior studies demonstrate that a proteinase fraction from Vasconcellea cundinamarcensis V.M. Badillo, Caricaceae, exhibits wound healing activity in gastric and cutaneous models and antitumoral/antimetastatic effects. Here, we present the toxicity, pharmacokinetics and biodistribution data for this proteinase fraction following a single dose into Swiss mice by i.v., s.c. or p.o. routes. The i.v. and s.c. toxicity assays demonstrate that proteinase fraction at ≤20 mg/kg is non-lethal after single injection, while parental administration (p.o.) of ≤300 mg/kg does not cause death. Based on p.o. acute toxicity dose using Organisation for Economic Cooperation and Development protocols, proteinase fraction ranks as Class IV “harmful” substance. Proteinase fraction shows high uptake determined as Kp (distribution tissue/blood) in organs linked to metabolism and excretion. Also, high bioavailability (≈100%) was observed by s.c. administration. The blood contents following i.v. dose fits into a pharmacokinetic bi-compartmental model, consisting of high removal constants – kel 0.22 h−1 and kd 2.32 h−1and a half-life – t½ = 3.13 h. The Ames test of proteinase fraction (0.01–1%) demonstrates absence of mutagenic activity. Likewise, genotoxic evaluation of proteinase fraction (5 or 10 mg/kg, i.p.) shows no influence in micronuclei frequency. In conclusion, the acute doses for proteinase fraction lack mutagenic and genotoxic activity, clearing the way for clinical assays.

Meat has played a crucial role in human evolution and is an important component of a healthy and well-balanced diet on account of its nutritional properties, its high biological value as a source of protein, and the vitamins and minerals it supplies. We studied the effects of animal fat reduction and substitution by hydrogenated vegetal fat, sodium alginate and guar gum. Fatty acid composition, lipid oxidation, color and instrumental texture as well as the sensorial difference between low, substituted-fat and the traditional formulations for mortadella-type products were analyzed. Both substitution and reduction of animal fat decreased the saturated fatty acids percentage from 40% down to 31%. A texture profile analysis showed differences between the formulations. Furthermore, lipid oxidation values were not significant for treatments as regards the type and quantity of fat used while the use of sodium alginate and guar gum reduced the amounts of liquid released after cooking. Animal fat substitution does cause, however, a difference in overall sensorial perception compared with non-substituted products. The results confirm the viability of substituting vegetal fat for animal fat.

PURPOSE:To investigate the effect of Botulinum toxin A (BoNTA) on skin flap viability in healthy, tobacco-exposed and diabetic rats.METHODS: Ninety male Wistar rats (250-300g) were randomly divided into six groups: control+saline (C1), control+BoNTA (C2), tobacco-exposed+saline (T1), tobacco-exposed+BoNTA (T2) diabetes+saline (D1) and diabetes+BoNTA (D2). A dorsal cutaneous flap (3×10cm) was performed. Survival area and total area of the flaps were measured. Lumen diameter, external arterial diameter and lumen/wall thickness ratio were recorded.RESULTS: Survival area increased in control group with BoNTA injection compared with control animals injected with saline (C2 x C1; 0.9±0.1 vs0.67±0.15, p= 0.001). A similar result was found in diabetes group injected with BontA (D2 x D1; 0.97±0.2 vs0.61±0.24, p=0.018). No difference was observed in skin flap viability in tobacco-exposed groups (T2 x T1; 0.74±0.24 vs 0.64±0.21, p=0.871). Lumen diameter (p= 0.004), external arterial diameter (p = 0.0046,) and lumen/wall thickness ratio (p= 0.003) were increased in diabetes+BoNTA-treated animals. This effect was not observed in control or in tobacco-exposed groups.CONCLUSIONS:Botulinum toxin A increased skin flap viability in control and diabetic rats on the seventh post-operative day. Increased lumen diameter, external arterial diameter, and lumen/wall thickness ratio were observed in the diabetes+BoNTA group. BoNTA had no effect in the tobacco-exposed group on the seventh postoperative day.

O objetivo do presente trabalho foi estimar as doses de exposição aos contaminantes chumbo (Pb) e cádmio (Cd) em crianças de 0 a 17 anos de idade via consumo de alimentos vegetais cultivados em quintais contaminados, localizados no entorno de uma metalúrgica desativada, no município de Santo Amaro, Estado da Bahia. Para a estimativa das doses foi utilizada a metodologia de avaliação de riscos sobre a saúde humana, especificamente a etapa de análise da exposição, determinando as concentrações dos metais e variáveis sociodemográficas das crianças. As doses de exposição estimadas para ambos os contaminantes superaram os valores recomendados pela Organização Mundial da Saúde (OMS), atingindo valores máximos de exposição de 166,9 μg.kg−1 dia−1 e 2,95 μg.kg−1 dia−1 para o Pb e o Cd, respectivamente, por consumo de frutas. Os resultados comprovam que o consumo de alimentos vegetais cultivados em quintais pela população residente próxima à antiga fábrica é uma importante rota de exposição atual aos metais, representando um risco para a saúde da população.

This paper aims to estimate the exposure of children between 0 to 17 years old to lead (Pb) and cadmium (Cd) via ingestion of vegetables cultivated in contaminated backyards located in the surroundings of a deactivated lead metallurgy in Santo Amaro, Bahia, Brazil. For the estimation of the exposure doses, the risk assessment on human health methodology, exposure analysis, was used, determining the concentrations of metals and socio-demographic variables of children. The estimated doses for both contaminants exceeded the values recommended by the World Health Organization (WHO). Maximum obtained values were 166.9 μg.kg−1 day−1 and 2.95 μg.kg−1day−1 for Cd and Pb, respectively, due to fruits consumption. The results show that the consumption of vegetables cultivated in the backyards by the population living near the deactivated metallurgical plant plays an important role in the exposition of the population to metals.

Several Lippia species have been used in folk medicine mainly for gastrointestinal and respiratory diseases. Their biological properties have been partially associated to the terpenoids found in their essential oils. According to the World Health Organization, cancer is the leading cause of death worldwide and is described as a complex group of diseases with several hallmarks. One of its acceptable defining features is the cell proliferation beyond their boundaries forming the tumors. Importantly, some drugs currently available were discovered by the investigation of plant secondary metabolites. Thus, this study aimed to evaluate in vitro cytotoxic effect of the essential oils extracted from five Lippia species against tumor cell lines. The results indicated that mouse colon carcinoma CT26.WT cell line viability was significantly reduced showing an IC50 of 19.05, 30.20 and 36.30 µg/ml when treated with the essential oils of L. sidoides, L. salviifolia and L. rotundifolia, respectively. Human lung carcinoma A549 cell line also had a compromised viability to the action of L. alba carvone chemotype essential oil. The tested essential oils did not compromise viability of the normal cell line CHO. These finds suggest that the studied Lippia essential oils might be good candidates for further in-depth studies.

This study evaluated the level of the metals Pb mg kg-1 and Cd mg kg-1 found in plant species and the contribution of the levels detected in contaminated soils located in the urban area of the city of Santo Amaro, Bahia. Levels were determined by graphite furnace and flame atomic absorption spectrometry. The results showed the presence of Pb and Cd in plant species at levels ranging from 0.18 to 118.2 mg kg-1 and 0.04 to 7.29 mg kg-1, respectively. The concentration values obtained varied according to the plant species and were not strongly influenced by the concentration values detected in the soil.
