Zeólitas como materiais alternativos para remoção de Zn+2 de soluções aquosas

The aim of this paper was to evaluate the capacity of zinc (Zn) removal in zeolitic materials available in the region of Planalto Catarinenese, in Southern Brazil (Zeobasalt), comparing its efficiency with a commercial zeolite from Cuba (Zeopure). The studies Zn removal capacity by the zeolites were separated in three stages, as follows: (i) no change in the ionic force and no change in solution pH; (ii) no change in the ionic force of the solution in two pH values of 4.5 and 5.5; and (iii) Zn removal in the presence of Cd and Cu. There was no statistical difference between the two zeolites for the mean percentage of Zn removal (98%), in pH 8.3. The adsorbed percentage of Zn was not influenced by the pH increase from 4.5 to 5.5. The presence of Cd e Cu did not influence the percentage of Zn removed.Este trabalho teve como objetivo avaliar a capacidade de remoção de zinco em materiais zeolíticos disponíveis na região do Planalto Catarinense (Zeobasalto), comparando sua eficiência com uma zeólita comercial proveniente de Cuba (Zeopura). Os estudos de capacidade de remoção de Zn pelas zeólitas foram divididos em três etapas: (i) sem alteração da força iônica e sem alteração do valor de pH da solução; (ii) sem alteração da força iônica da solução em dois valores de pH 4,5 e 5,5; e (iii) remoção de Zn na presença de Cd e Cu. Não houve diferença estatística entre as duas zeólitas para porcentagem média de remoção de Zn (98%), em pH 8,3. A porcentagem adsorvida de Zn não foi influenciada pelo aumento do pH de 4,5 para 5,5. A presença de Cd e Cu não influenciou a porcentagem removida de Zn

Caracterização de zeólitas do Município de Urupema, SC, e sua capacidade de remoção de Cu+2 de soluções aquosas

This work had as objective to characterize and evaluate the capacity of copper (Cu) removal of a zeolite available in the high lands of Santa Catarina State, south of Brazil (basalt zeolite), comparing its efficiency with a commercial zeolite coming from Cuba. The zeolite's mineralogical characterization was performed by X-ray diffractometry. The cationic capacity trade (CTC) was determined by the method of saturation with ammonium. The studies to assess the zeolite's capacity to remove Cu were carried out in two stages: (i) without changing the ionic force of the solution and the solution pH;(ii) without changing the ionic force of the solution in two values of pH (4.5 and 5.5). The X-ray diffractograms samples in environment and warmed temperatures showed the occurrence of clinoptilolite in the commercial zeolite, and heulandite in the basalt zeolite. The CTC of the commercial zeolite (Clinptilolite) was higher than the basalt zeolite (Heulandite). However, such differences were not reflected in the capacity of copper removal from the water solutions. There were no statistical differences between the two zeolites for the medium percentage of copper removal in pH 8.3. The Cu adsorption percentage was not influenced by the pH increase from 4.5 to 5.5.Este trabalho teve como objetivo caracterizar e avaliar a capacidade de remoção de cobre (Cu) de zeólitas disponíveis na região do Planalto Catarinense (zeólita basalto), comparando sua eficiência com uma zeólita comercial proveniente de Cuba. A caracterização mineralógica das zeólitas foi realizada por difratometria de raios-X. A capacidade de troca catiônica (CTC) foi determinada pelo método da saturação com amônio. Os estudos de capacidade de remoção de Cu pelas zeólitas foram divididos em duas etapas: (i) sem alteração da força iônica e sem alteração do valor de pH da solução; (ii) sem alteração da força iônica da solução em dois valores de pH 4,5 e 5,5. Os difratogramas de raios-X das amostras em temperatura ambiente e aquecidas evidenciaram a ocorrência de clinoptilolita na zeólita comercial, e heulandita na zeólita basalto. A CTC da zeólita comercial (Clinoptilolita) foi maior do que da zeólita basalto (Heulandita), porém isso não se refletiu na capacidade de remoção de cobre. Não houve diferença estatística entre as duas zeólitas para porcentagem média de remoção de cobre, em pH 8,3. A porcentagem adsorvida de Cu não foi influenciada pelo aumento do pH de 4,5 para 5,5

Physical activity, grape juice, red wine and resveratrol effects in cardiac remodeling of Wistar rats submitted to a high fat diet

Background: The association between regular physical activity and the polyphenol-rich drinks in models with a high fat diet, has not been sufficiently elucidated. Objective: The objective was to study the effects of the association among regular physical activity and polyphenol-rich drinks consumption in lipid profile and cardiac remodeling of Wistar rats submitted to the high fat diet. Methods: Rats Wistar, 90 days, 05 groups (n=10/group): Control Group (CG); High Fat Group (HG); Resveratrol Group (RG); Grape Juice Group (JG); Red Wine Group (WG); HG, RG, JG and WG received a high fat diet (20%). The animals performed a treadmill running protocol for 60 days. After, blood was collected for biochemical evaluation and heart was removed for histological analysis. Variables were expressed as mean ± standard deviation. ANOVA one way and Bonferroni or Tuckey`s as post-test, when appropriate, p < 0.05. Results: JG show higher total cholesterol (72.0 ±8.9 p<0.05) and HDL (28.0 ± 2.0 p<0.05) in relation to CG (total cholesterol = 57.8 ± 8.1, HDL = 24.4 ± 2.9). Collagen concentration: HG (9.65%, p<0.05) presented higher concentration in relation to the CG (3.68%), RG (4.73%), JG (3.57%) and WG (6.59%). Conclusions: It is concluded that the association between physical activity and drinks rich in polyphenols was able to protect the heart tissue from damage caused by the high fat diet

Introdução: O consumo elevado de gordura saturada e sedentarismo estão diretamente relacionados com a obesidade, podendo afetar os rins e alterar a pressão arterial. Objetivo: Analisar os efeitos da dieta hiperlipídica e bebidas ricas em polifenóis nos marcadores bioquímicos e histológicos renais e pressão arterial. Metodologia: Ratas Wistar, 90 dias de idade, recebendo água e ração ad libitum, divididas em 5 grupos: a) Grupo Controle (GC); b) Grupo Hiperlipídico (GH); c) Grupo Suco de uva integral (GS) (15mL/dia); d) Grupo Vinho tinto (GV) (10mL/dia) e e) Grupo Resveratrol (GR) (15mL/dia). Animais executaram protocolo de treinamento físico, 5dias/semana. Após 60 dias, os animais foram anestesiados e o sangue foi coletado para análises bioquímicas renais. Os rins foram retirados, medidos, pesados e processados para confecção de lâmina histológica. A pressão arterial foi aferida mediante pletismografia da cauda. Resultados representados como média±DP, ANOVA one way e Tukey ou Kruskal-Wallis e Dunn’s, considerados significativos quando p<0,05.  Resultados: os valores de ureia diminuíram no GS, GV e GR comparando com GH (p<0,0001); valores de ácido úrico menores no GS comparando com GH (p=0,01). GH, GS, GV e GR apresentaram diminuição do volume da área medular (p<0,003); densidade volumétrica do GS maior em comparação com o GH (p=0,003). A pressão arterial média (PAM) e pressão arterial sistólica (PAS) aumentaram significativamente no GH (p<0,0001 para ambos). Conclusão: Observou-se que o consumo das bebidas junto ao exercício físico foi capaz de reduzir os níveis de ureia e ácido úrico, assim como aumentar a densidade volumétrica renal diante de uma dieta hiperlipídica
