Allantoin as an independent marker associated with carotid intima-media thickness in subclinical atherosclerosis BJMBR
Santana,M.S.; Nascimento,K.P.; Lotufo,P.A.; Benseñor,I.M.; Meotti,F.C..
Allantoin is the main product of uric acid oxidation and was found to be augmented in atherosclerotic plaque in human autopsy and in animal models of atherosclerosis. Uric acid is abundant in human plasma and is prone to oxidation in inflammatory conditions such as atherosclerosis. In this study, we found a significant increase in plasma uric acid (P=0.002) and allantoin (P=0.025) in participants of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) that presented common carotid intima-media thickness (c-IMT) within the 75th percentile (c-IMT≥P75). Multiple linear regression showed an association of c-IMT with uric acid (β=0.0004, P=0.014) and allantoin (β=0.018, P=0.008). This association was independent of age, the traditional risk factor...

Antioxidant activity of rosemary and oregano ethanol extracts in soybean oil under thermal oxidation Ciênc. Tecnol. Aliment.
ALMEIDA-DORIA,R.F.; REGITANO-D'ARCE,Marisa A.B..
Four experiments were conducted to measure the antioxidant activity of ethanol extracts of rosemary and oregano compared with synthetic antioxidants such as TBHQ and BHA/BHT. The antioxidant activity was determined and results differed from those of the Oven test at 63º C. Peroxide values and absorptivities at 232 nm of soybean oil under Oven test were lower in treatments with 25, 50, 75, 100 and 200 mg.Kg-1 TBHQ than in treatments with 1000 mg.Kg-1 oregano extract (O), 500 mg.Kg-1 rosemary extract (R) and their mixture R+O. All the treatments were effective in controlling the thermal oxidation of oils; the natural extracts were as effective as BHA+BHT and less effective than TBHQ. The natural extracts were mixed with 25, 50, 75 and 100 mg.Kg-1 TBHQ and...

Antioxidant potential of oregano (Oreganum vulgare L.), basil (Ocimum basilicum L.) and thyme (Thymus vulgaris L.): application of oleoresins in vegetable oil Ciênc. Tecnol. Aliment.
Del Ré,Patrícia Vieira; Jorge,Neuza.
Studies have been carried out in order to increase the stability of vegetable oils due to economic and health protection reasons. There is a growing interest in the addition of natural antioxidants; especially herbs and spices. For this reason, this study aimed at evaluating the antioxidant potential of the oleoresins of oregano, basil, and thyme, as well as their behavior when applied to soybean oil under various concentrations. Firstly, the antioxidant activity was determined by the β-carotene/linoleic acid system and by the quantification of total phenolic compounds. Next, different concentrations of oleoresins (500 to 3000 mg.kg-1) were added to the soybean oil, and its antioxidant potential was analyzed using the oxidative stability through a Rancimat...

Avaliação do potencial antioxidante do extrato da casca de coco (Cocos nucifera L.) em biodiesel. Repositório Alice
MELO, N. L. M. de; OLIVEIRA, P. A. de; SOARES, I. P..
Desde a inserção do biodiesel na matriz energética nacional um dos temas frequentes nos debates é a qualidade do biocombustível. O fato se deve pela composição do biodiesel, que diferentemente do diesel de petróleo é formado por compostos oxigenados e com ligações duplas conjugadas, o que favorece os processos oxidativos. Assim, a estabilidade à oxidação é um dos parâmetros mais importantes na especificação do biodiesel. Em 2019 a Agência Nacional de Petróleo, Gás Natural e Biodiesel (ANP) publicou uma resolução que alterou de 8 para 12 horas o tempo mínimo de estabilidade no ensaio de oxidação acelerada. Para atingir esse parâmetro de qualidade, os fabricantes utilizam aditivos antioxidantes de base petroquímica que agregam custos ao produto. Dessa forma,...

Comment protéger les acides gras polyinsaturés à longues chaînes oméga 3 (AGPI -- LC ω3) vis-à-vis de l’oxydation ? ArchiMer
Genot, Claude; Eymard, Sylvie; Viau, Michèle.
Increase the consumption of long-chain omega 3 polyunsaturated fatty acids (LC ω3 PUFA) is highly recommended for their health benefits. However, these fatty acids are very prone to oxidation, which can impair sensory, nutritional and functional properties of foods. In this paper the various ways that increase LC ω3 PUFA stability during processing and storage of food products are reviewed. To efficiently protect LC ω3 PUFA during processing and storage of foods, a combined strategy, taking into account both the matrix and the process should be undertaken. First the quality of the raw materials should be rigorously controlled by, for example, increasing contents of in situ antioxidants and decreasing length of storage. Then, during processing and storage...

Durability of polydicyclopentadiene under high temperature, high pressure and seawater (offshore oil production conditions) ArchiMer
Le Gac, Pierre-yves; Choqueuse, Dominique; Paris, Marc; Recher, G.; Zimmer, Celine; Melot, D..
In the offshore industry polymer coatings are widely used to ensure thermal insulation of steel pipes, and to avoid over-cooling of the hot oil inside. Because of very severe service conditions (i.e. high temperature, high pressure and presence of seawater) and an expected life time of 20 years, durability of these coatings is a major issue for this industry. Polypropylene and polyurethane are often used for this application, nevertheless these polymers have some limitations in terms of processing time for polypropylene and maximum service temperature for polyurethane. Polycyclopentadiene (pDCPD) shows good processing characteristics and low thermal conductivity, so this polymer could be a good alternative coating in the offshore industry, but the...

Effec t of Freeze-Thaw Cycles on Lipid Oxidation and Myowater in Broiler Chickens Rev. Bras. Ciênc. Avic.
Ali,S; Rajput,N; Li,C; Zhang,W; Zhou,G.
ABSTRACT The present study was carried out to investigate the influence of freezing-thawing cycles (0, 2, 4 and 6) on lipid oxidation and myowater contents and distribution. Nine replicates of chicken breast meat samples were used for each cycle. Lipid oxidation was determined by measuring peroxide value, and malondialdehyde (MDA) concentrations, which reflect thiobarbituric acid reactive substance (TBARS). Color was determined with a digital colorimeter. Muscle moisture contents were determined by drip loss and thawing loss, water holding capacity, and nuclear magnetic resonance (NMR). The results showed that, as the number of freeze-thaw cycles increased, meat redness decreased and MDA and peroxide values increased. Drip loss and thawing loss tended to...

Silva-Kazama,Daniele Cristina da; Santos,Geraldo Tadeu dos; Pintro,Paula Toshimi Matumoto; Visentainer,Jesuí Vergílio; Kazama,Ricardo; Petit,Hélène Véronique; Marchi,Francilaine Eloise de.
Eight Holstein cows with body weight 570 ± 43 kg and 60 ± 20 lactation days were distributed in a double Latin square design with four 21-day periods to determine the effects of feeding ground or whole flaxseed with or without monensin supplementation (0.02% on a dry matter basis) on fatty acid profile of butter stored for 15 and 45 days. Ground flaxseed supply, in comparison to whole flaxseed, reduced relative percentages of 16:0, cis7-16:1, 17:0, and cis10-17:1 but it increased those of cis9,trans11-18:2, cis3-18:3, and omega 3 fatty acids in butter fat, reducing relative percentage of medium-chain fatty acids and increasing the content of polyunsaturated fatty acids. Supplementation with monensin increased relative percentages of cis9,trans11-18:2 and...

Effects of pyrogenic carbon feedstock and pyrolysis temperature on the oxidation kinetic and benzene polycarboxilic acids formation. Repositório Alice
CERQUEIRA, W. V.; RITTL, T. F.; PINHEIRO, M. A.; PEREIRA NETTO, A. D.; NOVOTNY, E. H..
Pyrogenic carbon (PyC) has a high potential to soil carbon sequestration. Among the methods used to quantify PyC, the method of benzene polycarboxilic acids (BPCA) is well-established. The oxidation step of this method is essential for a reliable PyC quantification. Up to now there are no studies on the influence of feedstock and pyrolysis temperature in the oxidation kinetic of PyC and BPCA formation; and then these are the purposes of this study. For this, different PyC were oxidised at 170 ºC during different times. The data showed similar kinetic curves for all PyC, but different BPCA production depending upon feedstock and pyrolysis temperature. All PyC showed maximum production of BPCA at 6-8 h under nitric acid oxidation at 170 ºC. We concluded that...

Fate of allelochemicals in the soil Ciência Rural
Vidal,Ribas Antonio; Bauman,Thomas Trost.
Allelochemicals are compounds released by one plant or plant residues that may have a negative or positive effect on other plant. The importance of allelopathy was extensively explored during the past three decades, with the work concentrating in the extraction and identification of the chemicals, and demonstration of activity in petry dish experiments. These compounds interact in the soil environment similarly as herbicides and are subject to processes of degradation such as microbial degradation, oxidation, and photolysis, and processes of removal or transfer, such as volatilization and adsorption. The objective of this review was to access the fate of allelochemicals in the soil environment to help to find strategies to increase its activity. The...

Abstract Virgin oil from avocados (Persea americana Mill.) is obtained by mechanical processes after pulp malaxation at temperatures that minimize oxidation and improve separation. The objective of this study was to assess the effect of time (0, 20, 30, 40, 60, 120 and 180 min) and temperature (40 and 50 °C) conditions during pulp malaxation on extraction yield, nutritional value (normalized fatty acid profile) and specific extintion (K232 and K270) of virgin oil extracted under laboratory conditions from avocados cultivated in southern Jalisco, Mexico. When pulp was malaxated for 120 min at 40 and 50 °C, a larger proportion of oil was extracted (82.9 ± 0.3% and 80.2 ± 0.8%, respectively). We observed that the normalized percentage of the fatty acids...

Phenolic compounds have shown to inhibit LDL oxidation in vitro and ex vivo; however, they are hydrosoluble compounds while LDL is a lipoprotein. Analysis of phenolic compounds in LDLs by HPLC is necessary to demonstrate their binding capacity to lipoproteins. We developed and validated a solid phase extraction method (SPE) that allowed us the purification of LDL samples and their analysis by HPLC. This methodology allowed us to demonstrate the in vitro binding capacity of tyrosol, one of the main phenolic compounds in olive oil, to LDL. In the intervention dietary study with volunteers, food rich in phenolic compounds affected LDL composition. Changes in LDL phenolics composition are not observed after the short-term ingestion of food rich in phenolic...

Kinetics of iron (II) oxidation in seawater of various pH OMA
Roekens, E.J.; Van Grieken, R.E..
The rate of iron(II) oxidation in the North Sea water of pH 5.5-10 in the range 10-25°C has been studied. The oxygenation rate depends linearly on the iron(II) and dissolved oxygen concentrations. The second-order dependence on (OH<sup>-</sup>), found by several investigators for synthetic solutions, was confirmed in seawater, but only for pOH>6.9. For pOH<5.9 the rate appeared to be independent of the pOH. In the intermediate range, pOH<5.9-6.9, corresponding to the natural pH of seawater, a first-order dependence on the pOH is obeyed. The important discrepancy in the literature between the second-order rate constant for NaCHO<sub>3</sub> solutions and for seawater can be attributed predominantly to the incorrect...
