Provedor de dados: 32
Autores: Avila Ramos, Fidel.
La oxidación de los ácidos grasos afecta la calidad de la carne, pero los antioxidantes reducen la oxidación, por lo que el tipo de antioxidante, la concentración y el método de aplicación pueden influir en la estabilidad oxidativa de la carne. Se realizaron tres experimentos, dos para evaluar la estabilidad oxidativa de carne cocida de pollo y uno para determinar los antioxidantes en la carne. En el experimento uno, se alimentaron pollos de engorda durante 42 días, con una dieta adicionada con Vitamina E (10 y 100 mg) y aceite de orégano (100 mg) kg-1 de alimento, incluyendo aceite de soya crudo (ASC) o aceite de soya acidulado (ASA).

The influence of organic solvents on estimates of genotoxicity and antigenotoxicity in the SOS chromotest
Provedor de dados: 74
Autores: Quintero,Nathalia; Stashenko,Elena E.; Fuentes,Jorge Luis.
In this work, the toxicity and genotoxicity of organic solvents (acetone, carbon tetrachloride, dichloromethane, dimethylsulfoxide, ethanol, ether and methanol) were studied using the SOS chromotest. The influence of these solvents on the direct genotoxicity induced by the mutagens mitomycin C (MMC) and 4-nitroquinoline-1-oxide (4-NQO) were also investigated. None of the solvents were genotoxic in Escherichia coli PQ37. However, based on the inhibition of protein synthesis assessed by constitutive alkaline phosphatase activity, some solvents (carbon tetrachloride, dimethylsulfoxide, ethanol and ether) were toxic and incompatible with the SOS chromotest. Solvents that were neither toxic nor genotoxic to E. coli (acetone, dichloromethane and methanol)...

Autores: 堀川, 実加; 小嶋, 道之; Horikawa, Mika; Kojima, Michiyuki.
ゴールデンベリーに含まれるイノシトールおよびビタミンEの含量は黄色や赤色ミニトマトのそれらよりも高かった。また、ゴールデンベリーのビタミンC含量は、赤色ミニトマトのそれよりも高く、還元力も高かった。ゴールデンベリー果実の登熟に従い、総クロロフィル量は減少したが、総カロテン、イノシトール、ビタミンEなど他の成分含量はすべて増加し、還元力や抗酸化活性も増大した。ゴールデンベリーの特徴的成分であるイノシトール量およびビタミンE量と 果実のa*値(赤味度)との間には、高い正の相関が認められた。これらの結果は、ゴールデンベリー果実のa*値は、登熟過程におけるこれらの成分量を推測する指標になることを示唆している。 The content of inositol and vitamin E included in Golden berry was higher than them of yellow and red mini-tomato. Also, vitamin C content and reduction activity of Golden berry were higher than that of red mini tomato. Quantity of total chlorophyll decreased Golden berry as ripening up, however other ingredient contents such as total carotene, inositol, vitamin E, reduction activity and antioxidant activity increased.

Probucol dramatically enhances dihydroartemisinin effect in murine malaria
Provedor de dados: 19
Autores: Kume, Aiko; Dang Trinh Minh Anh; Shichiri, Mototada; Ishida, Noriko; Suzuki, Hiroshi.
Background: Artemisinin-based combination therapy (ACT) has been adopted as national policy for the first-line treatment in large number of malaria-endemic regions. However, artemisinin-resistant parasites have emerged and are spreading, with slow-cleaning parasites being reported in patients treated with ACT. It means that more parasites are exposed to the partner drug alone and the risk of developing resistant parasites against the partner drug is increasing. Therefore, the development of a new method to enhance the effect of artemisinin is required. In this study, the potential effect of probucol as a combination drug of dihydroartemisinin (DHA), an artemisinin derivative, was examined. Methods: C57BL/6 J mice infected with Plasmodium yoelii XL-17 were...

Simultaneous determination of a-tocopheryl acetate and tocopherols in aquatic organisms and fish feed
Provedor de dados: 27
Autores: Huo, J.-Z.; Nelis, H.; Lavens, P.; Sorgeloos, P.; De Leenheer, A.P.
In aquaculture, alpha-tocopheryl acetate (alpha-TA) is the main source of vitamin E used to fortify fish feed. Alpha-TA in fish is often determined indirectly, i.e. by alkaline hydrolysis, followed by quantitation of ‘total alpha-tocopherol’ (alpha-T) and substraction of the natively present alpha-T. The aim of this study was to develop an HPLC method for the simultaneous quantitative determination of alpha-TA and free tocopherols in aquatic organisms and fish feed. The assay consists of a simple extraction with methanol containing butylhydroxytoluene (BHT) as an antioxidant, followed by reversed-phase chromatography with consecutive UV and fluorescence detection of alpha-TA and tocopherols, respectively. The peak of the internal standard tocol in the...

Provedor de dados: 89
Autores: Silva,ICM da; Ribeiro,AML; Canal,CW; Vieira,MM; Pinheiro,CC; Gonçalves,T; de Moraes,ML; Ledur,VS.
Studies on the relationships between animal nutrition and immunity have sought reliable methodologies to measure responses. Cell-mediated immune response is similarly studied in humans. The cutaneous basophil hypersensitivity test (CBH) is one of the methods to measure that response and consists in the infiltration of inflammatory cells, particularly of lymphocytes and basophils, as result of the application of substances capable of inducing cell proliferation in determined sites, such as wings, wattle, and interdigital space in birds. CBH is considered a simple and fast method and can be applied in birds of different ages. In immunocompetence studies with poultry, phytohemagglutinin-P (PHA-P) is a commonly used substance, despite the variability of the...

Antioxidant supplementation to the exercising horse
Provedor de dados: 96
Autores: Williams,Carey A.
Evidence of oxidative stress in horses has been described in reports dealing with intense and endurance exercise. Oxidative stress occurs when antioxidant systems are insufficient causing oxidation to potentially damage DNA, proteins, and lipids, and contribute to degenerative changes. Vitamin E is the most commonly supplemented antioxidant in horses and has been shown that horses in exercise conditioning may require higher intakes of vitamin E than recommended. Also in various species vitamin C potentiates the effects of vitamin E; however, under maintenance conditions horses have the ability to synthesize sufficient ascorbate, the demand increases as stress on the body is increased. Competitive endurance horses were estimated to consume 1.2 to 5-times...

Provedor de dados: 42
Autores: Oliveira,Olga M.M.F.; Brunetti,Iguatemy L.; Khalil,Najeh M.
In this study, the effect of nicotine on the LDL oxidation by the MPO/H2O2/Cl- system and the effect of HOCl on LDL and some of its components, such as methyl linoleate, vitamin E and the amino acid tryptophan were explored. Nicotine, in micromolar concentrations, enhanced the tryptophan oxidation, either present in LDL or free, in solution. Nicotine also decreased the formation of conjugated dienes and oxygen consumption in a methyl linoleate / HOCl system, and there was evidence to suggest an increase in chlorohydrin formation. Acceleration of the vitamin E oxidation by HOCl was also observed in the presence of nicotine. These data show that the interaction of nicotine and HOCl can promote significant biochemical modifications in LDL particle and some of...

Protection against cephalosporin-induced lipid peroxidation and nephrotoxicity by (+)-cyanidanol-3 and vitamin E
Provedor de dados: 56
Autores: Cojocel,C.; Tolle,K.-L.; El-Hajj,H.; Baumann,K.
The ability of the clinically used cephalosporins: cephalothin, cefotaxime and cefotiam to induce lipid peroxidation (LPO) and renal damage was compared to that of nephrotoxic cephaloridine under in vivo conditions. Glutathione was measured in rat liver or in renal cortex as non-protein sulfhydryls. LPO was measured in plasma, renal cortex and liver by the generation of malondialdehyde or as the increase in renal cortical concentration of conjugated dienes. Impairment of renal function was measured as the decrease in renal cortical accumulation of the organic anion p-aminohippurate (PAH). Administration of cephalosporins to rats as a single dose (2000 mg/kg, ip) induced a significant glutathione-depletion in the renal cortex with cephaloridine, and in the...

Provedor de dados: 56
Autores: Kalender,S.; Kalender,Y.; Ates,A.; Yel,M.; Olcay,E.; Candan,S.
Idarubicin is an anthracycline antibiotic extensively used in acute leukemia. In the present study we investigated whether vitamin E and catechin can reduce the toxic effects of idarubicin. Vitamin E (200 IU kg-1 week-1), catechin (200 mg kg-1 week-1), idarubicin (5 mg kg-1 week-1), idarubicin + vitamin E (200 IU kg-1 week-1), and idarubicin + catechin (200 mg kg-1 week-1) combinations were given to male Sprague-Dawley rats weighing 210 to 230 g (N = 6/group). Idarubicin-treated animals exhibited a decrease in body and heart weight, a decrease in myocardial contractility, and changes in ECG parameters (P&lt;0.01). Catechin + idarubicin- and vitamin E + idarubicin-treated groups exhibited similar alterations, but changes were attenuated in comparison to...

alpha-Tocopherol enhances tumour growth inhibition by cis-dichlorodiammine platinum (II)
Provedor de dados: 56
Autores: Sarna,S.; Kumar,A.; Bhola,R.K.
Present studies indicate that alpha-tocopherol enhances the efficacy of cisplatin as demonstrated by inoculation of Dalton's lymphoma cells incubated with either cisplatin (5 or 10 µg/ml) alone or cisplatin + alpha-tocopherol (25 or 50 µg/ml) into C3H/He mice. Tumour cells (3 x 10(6) cells/mouse) incubated with cisplatin grow slowly in syngeneic mice as indicated by the late appearance of tumour. However, mice failed to develop tumour when inoculated with tumour cells incubated with cisplatin + alpha-tocopherol. When the animals were challenged with tumour cells (3 x 10(6) cells/mouse) on the 15th day after the initial inoculation, 30-50% survived more than 60 days, with 10% tumour-free survivors being observed in some groups. Antitumour activity was...

The objective of the study is to evaluate meat quality from Ile de France lamb fed diets supplemented with sunflower seeds and vitamin E. Thirty-two lamb weighing initially 15kg were housed in individual stalls and slaughtered when body weight reached 32kg. The treatments consisted of four experimental diets: D1) sugarcane + concentrate without sunflower seeds; D2) sugarcane + concentrate with sunflower seeds; D3) sugarcane + concentrate without sunflower seeds plus 1000mg vitamin E kg-1 diet dry matter (DM); and D4) sugarcane + concentrate with sunflower seeds and 1000mg vitamin E kg-1 diet DM. The parameters temperature, pH, color, cooking loss, shear force and water holding capacity were determined at maturation times of 0, 7 and 14 days on the...

Feeding different levels of vitamin E and selenium has no effect on serum immunoglobulin Y (IgY) production by layers vaccinated against Escherichia coli and avian encephalomyelitis virus
Provedor de dados: 65
Autores: Kindlein,Giselle; Ribeiro,Andréa Machado Leal; Canal,Cláudio Wageck; Vieira,Maitê de Moraes.
The effects of vitamin E and selenium (Se) supplementation on the immunity of hens vaccinated against a mixture of six swine-pathogenic Escherichia coli (EC) and avian encephalomyelitis virus (AEV) were studied. Antibody production (AbP) was evaluated in ninety 49 to 57-week-old H&amp;N Nick Chick hens fed diets containing 14IU Vitamin E kg-1 (basal diet), 27, 59, 111, or 111IU vitamin E kg-1 + 0.56ppm Se supplementation. At 51 wks of age, half of the hens were vaccinated against EC, and all birds were vaccinated against AEV. At 53-weeks of age, the birds received a second dose of EC vaccine. Blood samples were collected weekly and serum was analyzed by ELISA for anti-EC IgY and was expressed as optical density (OD). Vaccinated hens had higher serum OD...
