[Ab] Resumo:Simultaneous removal process of SO and NO from flue gas using vacuum ultraviolet light (VUV)/heat/peroxymonosulfate (PMS) in a VUV spraying reactor was proposed. The key influencing factors, active species, reaction products and mechanism of SO and NO simultaneous removal were investigated. The results show that vacuum ultraviolet light (185 nm) achieves the highest NO removal efficiency and yield of and under the same test conditions. NO removal is enhanced at higher PMS concentration, light intensity and oxygen concentration, and is inhibited at higher NO concentration, SO concentration and solution pH. Solution temperature has a double impact on NO removal. CO concentration has no obvious effect on NO removal. and produced from VUV-activation of PMS play a leading role in NO removal. O and ·O produced from VUV-activation of O also play an important role in NO removal. SO achieves complete removal under all experimental conditions due to its very high solubility in water and good reactivity. The highest simultaneous removal efficiency of SO and NO reaches 100% and 91.3%, respectively.

[Ab] Resumo:The aldehyde 3-S-glutathionylhexanal is an intermediate which is produced during the formation of the wine aroma precursor 3-S-glutathionylhexanol, after the reaction of glutathione with trans-2-hexenal. This study was conducted to assess whether the chemical, as opposed to the enzymatic, production of 3-S-glutathionylhexanal could occur at a significant rate in grape juice. LC-MS/MS was used in low- and high-resolution modes, in combination with functional group derivatization, to identify and quantitate products. In comparison to cysteine, glutathione was found to induce less cyclized products on reaction with trans-2-alkanals and the glutathione-derived products were more reactive to hydrogen sulfite. The zero-order rates for 3-S-glutathionylhexanal formation in model grape juice were 1.08 ± 0.08 and 0.45 ± 0.05 mg/(L·day) glutathione equivalents at 25 and 13 °C, respectively, and the reaction rate increased 3-fold by increasing the pH from 3.2 to 3.8. 3-S-Glutathionylhexanal was detected in all five white grape juices examined. The concentration of the aldehyde could be increased by up to 10-fold after being released from hydrogen sulfite, demonstrating a potentially novel source for the production of varietal thiol aroma compounds in wine.

[Ti] Título:Sulfur dioxide exposure enhances Th2 inflammatory responses via activating STAT6 pathway in asthmatic mice.

[Ab] Resumo:Sulfur dioxide (SO ) is one of potential risk factors for induction and/or exacerbation of asthma, but the underlying mechanisms are not well understood. In this study, we investigate the role of SO in asthma using a classical asthmatic model with allergic airway inflammation by treating C57BL/6 mice with ovalbumin (OVA) and/or 10 mg/m SO . Our results showed that SO exposure alone induced slight pathological changes but did not significantly increase inflammatory cell counts, pro-inflammatory cytokine expression, and mucus production in the airway of mice, whereas SO exposure in OVA-induced asthmatic mice caused marked pulmonary pathological changes and significantly increased the counts of eosinophil-rich leukocytes compared with OVA alone asthmatic mice. The expression of MUC5AC, TNF-α, Th2 cytokines (IL-4, IL-5, and IL-13) and STAT6 was further up-regulated in OVA plus SO treated mice compared with OVA alone treated mice. In addition, exposure to SO alone markedly elevated STAT6 mRNA levels and hydrogen peroxide (H O ) content in the lung. These findings suggest that SO amplifies Th2 inflammatory responses in OVA-induced asthmatic mice by activating STAT6, which can further induce Th2 cytokine expression. Induction of STAT6 expression might be an important mechanism underlying the increased risk for asthma after environmental exposure.

[Ab] Resumo:The performance of a biofilter for off-gas treatment relies on the activity of microorganisms and adequate O and H O. In present study, a microelectrode was applied to analyze O in polyurethane foam cubes (PUFCs) packed in a biofilter for SO removal. The O distribution varied with the density and water-containing rate (WCR) of PUFCs. The O concentration dropped sharply from 10.2 to 0.8mg/L from the surface to the center of a PUFC with 97.20% of WCR. The PUFCs with high WCR presented aerobic-anoxic-aerobic areas. Three-dimensional simulated images demonstrated that the structure of PUFCs with high WCR consisted of an aerobic "shell" and an anoxic "core", with high-density PUFCs featuring a larger anoxic area than low-density PUFCs. Moreover, the H O distribution in the PUFC was uneven and affected the O concentration. Whereas aerobic bacteria were observed in the PUFC surface, facultative anaerobic microorganisms were found at the PUFC core, where the O concentration was relatively low. O and H O distributions differed in the PUFCs, and the distribution of microorganisms varied accordingly.

[Ab] Resumo:To evaluate the association between atmospheric inhalable particulate matter (PM(10)) concentration and cardiovascular diseases burden in Tianjin. The data on daily mean concentrations of main pollutants (PM(10), nitrogen dioxide(NO(2)) and sulfur dioxide(SO(2))), meteorological factors (temperature and relative humidity) and population death monitoring data in Tianjin, from January 1, 2001 to December 31, 2010, were collected and analyzed in this study. The death counts and years of life lost were simultaneously used as the indicators of disease burden. The generalized additive model was used to assess the associations between PM(10) and daily death counts and years of life lost due to cardiovascular system diseases in Tianjin by adjusting the confounding factors such as long-term trend, seasons, meteorological factors and other factors related to the long-term variability. The daily average concentration of PM(10) was 117.6 µg/m³ in Tianjin during 2001 to 2011. The daily average number of deaths of cardiovascular system diseases, cerebrovascular diseases and ischemic heart diseases in Tianjin were 38.4, 14.8 and 17.2 people respectively, and the daily average years of life lost were 776.8, 306.5 and 326.1 person years respectively. The effects of PM(10) on the daily death counts of the three diseases categories were statistically significant (all 0.01) in Tianjin and the maximum effect occurs at the moment when PM(1)0 was at moving average concentration of today and lagged 1-day (Lag01). The effects of decreasing order were ischemic heart diseases, cardiovascular system diseases and cerebrovascular diseases, excess risks were 0.53% (95% 0.35%-0.71%), 0.40% (95% 0.28%-0.53%) and 0.38% (95% 0.19%-0.56%). The effects of atmospheric PM(10) on the years of life lost of the three diseases were also statistically significant on the different lag days (all 0.01) in Tianjin and the maximum effect of PM(10) appeared in Lag01. The effects from the largest to the lowest were 2.86 (95% 1.79-3.93) person years for cardiovascular system diseases, 1.59 (95% 0.95-2.23) person years for ischemic heart diseases and 1.07 (95% 0.43-1.71) person years for cerebrovascular diseases, respectively. In multi-pollutant models, after controlling SO(2), the effect of PM(10) on the daily life loss of above 3 kinds of diseases was higher than that of single pollutant model. In contrast, after controlling SO(2) or SO(2) with NO(2), the effect was lower. After controlling NO(2), the effect of PM(10) on the daily life loss of cerebrovascular disease was no longer statistically significant ( 0.05). Exposure to atmospheric PM(10) can significantly increase the cardiovascular diseases burden in Tianjin, especially for ischemic heart diseases. These results suggested that particular attention should be paid to reduce the exposure to atmospheric inhalable particulate matter for patients with ischemic heart diseases.

[Ti] Título:Wine microbiology is driven by vineyard and winery anthropogenic factors.

[Ab] Resumo:The effects of different anthropic activities (vineyard: phytosanitary protection; winery: pressing and sulfiting) on the fungal populations of grape berries were studied. The global diversity of fungal populations (moulds and yeasts) was performed by pyrosequencing. The anthropic activities studied modified fungal diversity. Thus, a decrease in biodiversity was measured for three successive vintages for the grapes of the plot cultivated with Organic protection compared to plots treated with Conventional and Ecophyto protections. The fungal populations were then considerably modified by the pressing-clarification step. The addition of sulfur dioxide also modified population dynamics and favoured the domination of the species Saccharomyces cerevisiae during fermentation. The non-targeted chemical analysis of musts and wines by FT-ICR-MS showed that the wines could be discriminated at the end of alcoholic fermentation as a function of adding SO or not, but also and above all as a function of phytosanitary protection, regardless of whether these fermentations took place in the presence of SO or not. Thus, the existence of signatures in wines of chemical diversity and microbiology linked to vineyard protection has been highlighted.

[Ab] Resumo:In recent decades, it has been found the existence of a new class of biologically active substances - gaseous mediators (gasotransmitters), performing in the cells the signaling function and with high specificity involved in the intercellular and intracellular communication. This review characterizes the main gasotransmitters: nitric oxide, carbon monoxide, hydrogen sulfide, sulfur dioxide and polysulfides. Their physiological role and involvement in the pathogenesis of diseases is described. Basic information about main gasotransmitters is generalized in the original table. Nitrate-Nitrite background, which is a chemical background of the existence of modern man, affects the intra- and intercellular signaling system, alters the ultrastructure of neurons, neuron-neuron and neuron-glia interaction, eliminates the effects of endogenous gasotransmitters and affects the average life expectancy. In accordance with the principle of cyclicity is proposed and substantiated the hypothesis of the existence of "hydrogen sulfide cycle", combining three sulfur-containing gasotransmitters. It is suggested that the cyclic organization of gasotransmitters in the cells and the whole body can be due to the existence of a global principle of cyclicity, which can spread its influence on almost all the structural and functional levels in the animate and inanimate nature.

[Ab] Resumo:The four different methods of color measurement of wine proposed by Boulton, Giusti, Glories and Commission International de l'Eclairage (CIE) were applied to assess the statistical relationship between the phytochemical profile and chromatic characteristics of sulfur dioxide-free mulberry (Morus nigra) wine submitted to non-thermal maturation processes. The alteration in chromatic properties and phenolic composition of non-thermal aged mulberry wine were examined, aided by the used of Pearson correlation, cluster and principal component analysis. The results revealed a positive effect of non-thermal processes on phytochemical families of wines. From Pearson correlation analysis relationships between chromatic indexes and flavonols as well as anthocyanins were established. Cluster analysis highlighted similarities between Boulton and Giusti parameters, as well as Glories and CIE parameters in the assessment of chromatic properties of wines. Finally, principal component analysis was able to discriminate wines subjected to different maturation techniques on the basis of their chromatic and phenolics characteristics.

[Ab] Resumo:The present study was designed to investigate whether endogenous sulphur dioxide (SO ) controlled pulmonary inflammation in a rat model of oleic acid (OA)-induced acute lung injury (ALI). In this model, adenovirus expressing aspartate aminotransferase (AAT) 1 was delivered to the lungs, and the levels of SO and proinflammatory cytokines in rat lung tissues were measured. In the human alveolar epithelial cell line A549, the nuclear translocation and DNA binding activities of wild-type (wt) and C38S (cysteine-to-serine mutation at p65 Cys ) NF-κB p65 were detected. GFP-tagged C38S p65 was purified from HEK 293 cells and the sulphenylation of NF-κB p65 was studied. OA caused a reduction in SO /AAT pathway activity but increased pulmonary inflammation and ALI. However, either the presence of SO donor, a combination of Na SO and NaHSO , or AAT1 overexpression successfully blocked OA-induced pulmonary NF-κB p65 phosphorylation and consequent inflammation and ALI. Either treatment with an SO donor or overexpression of AAT1 down-regulated OA-induced p65 activity, but AAT1 knockdown in alveolar epithelial cells mimicked OA-induced p65 phosphorylation and inflammation Mechanistically, OA promoted NF-κB nuclear translocation, DNA binding activity, recruitment to the intercellular cell adhesion molecule (ICAM)-1 promoter, and consequent inflammation in epithelial cells; these activities were reduced in the presence of an SO donor. Furthermore, SO induced sulphenylation of p65, which was blocked by the C38S mutation on p65 in epithelial cells. Hence, down-regulation of SO /AAT is involved in pulmonary inflammation during ALI. Furthermore, SO suppressed inflammation by sulphenylating NF-κB p65 at Cys .

[Ab] Resumo:Lignin and ash material balances of SO -ethanol-water (AVAP®) fractionation of sugarcane (SC) straw were thoroughly studied at various conditions. Most of straw lignin and ash dissolve in the liquor and 40-80% of lignin is precipitated after ethanol removal as a pure (∼99%) and sulfur-lean (<2%) fraction. Most of the acid-soluble ash and its elements (Na, K, Fe, Al) as well as large portion of silica are removed from the fiber phase. Straw lignin behavior exhibited differences compared to wood lignin including high apparent content in fiber, higher degree of sulfonation of dissolved lignin, and dense char-like precipitate formation upon ethanol removal. Variation in fractionation conditions did not have significant effect on lignin properties, while post-sulfonation was capable of changing its form from char-like to colloidal precipitate.
