POSTURAL EVALUATION OF MEN AGED BETWEEN 60 AND 65 YEARS OLD OF PORTO ALEGRE-RS BASED ON SHADOW MOIRÉ TECHNIQUE

This is a population-based study and it is part of the Multidimensional Study of the Elderly population of Porto Alegre-RS. The aim was to evaluate the posture of men aged between 60 and 65 years using the Shadow Moiré Technique. The variables analyzed were: the mean angular variation of posture deviations evaluated, considering the cervical-thoracic column (CTC) and thoracic-lumbar column (TLC); hyperkyphosis, misalignment of the scapulas and its correlation with lateral deviation of the column. Results showed that 44.4% of the tested population presented Very Low deviations of the CCT and 74% had Very Low and Low deviations of the TLC. The findings of this study failed to prove the correlation between the misalignment of the scapulas and column deviations. Fifty-two % presented hyperkyphosis

POSTURAL EVALUATION OF MEN AGED BETWEEN 60 AND 65 YEARS OLD OF PORTO ALEGRE-RS

This is a population-based study and it is part of the Multidimensional Study of the Elderly population of Porto Alegre-RS. The aim was to evaluate the posture of men aged between 60 and 65 years old using a postural grid, classified as a qualitative method. The volunteer’s posture was evaluated on Frontal plan (posterior view) and Sagittal plan (right view). The results demonstrated that most volunteers presented an erect head and cervical column. Fifty one percent had the right shoulder more elevated. Deviations of thoracic and lumbar columns and pelvis were not prominent in the population studied. Upper limbs were normally aligned in 26% of volunteers. Geno varus posture was present in 18,5%. The evaluation of the images obtained in the Sagittal plan indicated that 48% of the volunteers presented a lordotic-kyphotic posture

Pure niobia as catalyst for the oxidation of organic contaminants: Mechanism study via ESI-MS and theoretical calculations

In this work, synthetic and natural niobium oxide (niobia), were used to promote the oxidation of methylene blue dye. The samples were characterized by XRD, XPS and FTIR measurements. The presence of reactive species on the surface of the samples strongly increases the oxidation rate of the methylene blue dye. The reaction mechanism was studied by ESI-MS analyses. Moreover, kinetic data and XPS spectroscopy suggest that the oxidation of the organic dye involves oxidizing species mainly generated after previous treatment with H2O2. The results also showed that the oxidation takes place by a homolytic mechanism via radical intermediates.Fil: Oliveira, Luiz C. A.. Universidad Federal de Lavras; BrasilFil: Ramalho, Teodorico C..

Avaliação da atividade antibacteriana de extrato de folhas de goiabeira, Psidium guajava Linnaeus, sobre bactérias entéricas diarreiogênicas, isoladas de camarão sete-barbas, Xiphopenaeus kroyeri (Heller)

Guava leaf tea of Psidium guajava Linnaeus is commonly used as a medicine against gastroenteritis and child diarrhea by those who cannot afford or do not have access to antibiotics. This study screened the antimicrobial effect of essential oils and methanol, hexane, ethyl acetate extracts from guava leaves. The extracts were tested against diarrhea-causing bacteria: Staphylococcus aureus, Salmonella spp. and Escherichia coli. Strains that were screened included isolates from seabob shrimp, Xiphopenaeus kroyeri (Heller) and laboratory-type strains. Of the bacteria tested, Staphylococcus aureus strains were most inhibited by the extracts. The methanol extract showed greatest bacterial inhibition. No statistically significant differences were observed between the tested extract concentrations and their effect. The essential oil extract showed inhibitory activity against S. aureus and Salmonella spp. The strains isolated from the shrimp showed some resistance to commercially available antibiotics. These data support the use of guava leaf-made medicines in diarrhea cases where access to commercial antibiotics is restricted. In conclusion, guava leaf extracts and essential oil are very active against S. aureus, thus making up important potential sources of new antimicrobial compounds.O chá de folhas de goiaba Psidium guajava Linnaeus é comumente usado como remédio nas gastrenterites e diarréias infantis por aqueles que não têm acesso a antibióticos. Esta pesquisa estudou o efeito antibacteriano sobre bactérias causadoras de diarréias, do óleo essencial e do extrato de folhas de goiabeira usando como diluente: metanol, hexano e acetato de etila. Os extratos foram testados sobre Staphylococcus aureus, Salmonella spp. e Escherichia coli. As bactérias testadas foram isoladas de camarão sete-barbas Xiphopenaeus kroyeri (Heller) usando-se como controle cepas padrão, de cada espécie. Das bactérias testadas, o melhor efeito inibitório foi observado sobre Staphylococcus aureus. O extrato de metanol apresentou maior inibição bacteriana. O óleo essencial mostrou ação inibitória contra S. aureus e Salmonella spp. Foi demonstrada alguma resistência das cepas isoladas de camarão aos antibióticos comerciais testados. Estes dados confirmam que remédios à base de folhas de goiabeira podem ser utilizados em casos de diarréia provocada por essas bactérias, quando o uso de antibiótico for restrito. Conclui-se que extratos de folhas de goiaba e o seu óleo essencial são muito ativos contra S. aureus, tornando-os importantes fontes em potencial de novos compostos antimicrobianos

Expanding the knowledge on lignocellulolytic and redox enzymes of worker and soldier castes from the lower termite coptotermes gestroi

Termites are considered one of the most efficient decomposers of lignocelluloses on Earth due to their ability to produce, along with its microbial symbionts, a repertoire of carbohydrate-active enzymes (CAZymes). Recently, a set of Pro-oxidant, Antioxidant, and Detoxification enzymes (PAD) were also correlated with the metabolism of carbohydrates and lignin in termites. The lower termite Coptotermes gestroi is considered the main urban pest in Brazil, causing damage to wood constructions. Recently, analysis of the enzymatic repertoire of C. gestroi unveiled the presence of different CAZymes. Because the gene profile of CAZy/PAD enzymes endogenously synthesized by C. gestroi and also by their symbiotic protists remains unclear, the aim of this study was to explore the eukaryotic repertoire of these enzymes in worker and soldier castes of C. gestroi. Our findings showed that worker and soldier castes present similar repertoires of CAZy/PAD enzymes, and also confirmed that endo-glucanases (GH9) and beta-glucosidases (GH1) were the most important glycoside hydrolase families related to lignocellulose degradation in both castes. Classical cellulases such as exo-glucanases (GH7) and endo-glucanases (GH5 and GH45), as well as classical xylanases (GH10 and GH11), were found in both castes only taxonomically related to protists, highlighting the importance of symbiosis in C. gestroi. Moreover, our analysis revealed the presence of Auxiliary Activity enzyme families (AAs), which could be related to lignin modifications in termite digestomes. In conclusion, this report expanded the knowledge on genes and proteins related to CAZy/PAD enzymes from worker and soldier castes of lower termites, revealing new potential enzyme candidates for second-generation biofuel processes7CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESP140796/2013-4; 310186/2014-5; 442333/2014-511/20977-3; 15/06971-3; 12/19040-0; 14/10351-8; 06/59086-8; 14/20576- 7; 13/03061-0; 10/11469-1; 08/58037-9; 14/50371-8; 08/50114-

Serum sclerostin is an independent predictor of mortality in hemodialysis patients

Background\ud Sclerostin (Scl) has recently emerged as a novel marker of bone remodeling and vascular calcification. However, whether high circulating Scl is also a risk factor for death is not well established. The purpose of this study was to test whether serum Scl would be associated with mortality.\ud \ud \ud Methods\ud we measured serum Scl in a hemodialysis patients’ cohort, which was followed during a ten-year period. Competing risk regression models were applied, as during the follow-up, patients were exposed to both events kidney transplant and death.\ud \ud \ud Results\ud Ninety-one patients aged 42.3 ± 18.8 years (55% of male gender, 15% of diabetes) were included. During the follow-up, 32 patients underwent kidney transplant and 26 patients died. Non-survivals presented higher FGF23, higher Scl and lower creatinine. There was an association between all-cause mortality and higher Scl (HR = 2.2), higher age (HR = 1.04) and presence of diabetes (HR = 2.27), by competing risk analyses. Even including potential markers of mortality, as creatinine, FGF 23, and gender, Scl, age and diabetes remained significantly related to higher mortality.\ud \ud \ud Conclusion\ud Serum Scl is an independent predictor of mortality in dialysis patients. However, whether clinical interventions to modulate Scl would be able to improve these patients survival needs to be determined.Fapes
