Double-blind intervention trial on modulation of ozone effects on pulmonary function by antioxidant supplements. (1/13910)

The aim of this study was to investigate whether the acute effects of ozone on lung function could be modulated by antioxidant vitamin supplementation in a placebo-controlled study. Lung function was measured in Dutch bicyclists (n = 38) before and after each training session on a number of occasions (n = 380) during the summer of 1996. The vitamin group (n = 20) received 100 mg of vitamin E and 500 mg of vitamin C daily for 15 weeks. The average ozone concentration during exercise was 77 microg/m3 (range, 14-186 microg/m3). After exclusion of subjects with insufficient compliance from the analysis, a difference in ozone exposure of 100 microg/m3 decreased forced expiratory volume in 1 second (FEV1) 95 ml (95% confidence interval (CI) -265 to -53) in the placebo group and 1 ml (95% CI -94 to 132) in the vitamin group; for forced vital capacity, the change was -125 ml (95% CI -384 to -36) in the placebo group and -42 ml (95% CI -130 to 35) in the vitamin group. The differences in ozone effect on lung function between the groups were statistically significant. The results suggest that supplementation with the antioxidant vitamins C and E confers partial protection against the acute effects of ozone on FEV1 and forced vital capacity in cyclists.  (+info)

Inflammatory cell-mediated tumour progression and minisatellite mutation correlate with the decrease of antioxidative enzymes in murine fibrosarcoma cells. (2/13910)

We isolated six clones of weakly tumorigenic fibrosarcoma (QR) from the tumorigenic clone BMT-11 cl-9. The QR clones were unable to grow in normal C57BL/6 mice when injected s.c. (1x10(5) cells). However, they formed aggressive tumours upon co-implantation with a 'foreign body', i.e. a gelatin sponge, and the rate of tumour take ranged from 8% to 58% among QR clones. The enhanced tumorigenicity was due to host cell-mediated reaction to the gelatin sponge (inflammation). Immunoblot analysis and enzyme activity assay revealed a significant inverse correlation between the frequencies of tumour formation by QR clones and the levels of manganese superoxide dismutase (Mn-SOD, P<0.005) and glutathione peroxidase (GPchi, P<0.01) in the respective tumour clones. Electron spin resonance (ESR) revealed that superoxide-scavenging ability of cell lysates of the QR clone with high level of Mn-SOD was significantly higher than that with low level of the antioxidative enzyme in the presence of potassium cyanide, an inhibitor for copper-zinc superoxide dismutase (CuZn-SOD) (P<0.001). Minisatellite mutation (MSM) induced by the inflammatory cells in tumour cells were investigated by DNA fingerprint analysis after QR clones had been co-cultured with gelatin-sponge-reactive cells. The MSM rate was significantly higher in the subclones with low levels of Mn-SOD and GPchi (P<0.05) than in the subclones with high levels of both enzymes. The MSM of the subclones with low levels of both enzymes was inhibited in the presence of mannitol, a hydroxyl radical scavenger. The content of 8-hydroxydeoxyguanosine (8-OHdG) by which the cellular DNA damage caused by active oxygen species can be assessed was significantly low in the tumours arising from the QR clone with high levels of Mn-SOD and GPchi even if the clone had been co-implanted with gelatin sponge, compared with the arising tumour from the QR clone with low levels of those antioxidative enzymes (P<0.001). In contrast, CuZn-SOD and catalase levels in the six QR clones did not have any correlation with tumour progression parameters. These results suggest that tumour progression is accelerated by inflammation-induced active oxygen species particularly accompanied with declined levels of intracellular antioxidative enzymes in tumour cells.  (+info)

Synergistic protective effects of antioxidant and nitric oxide synthase inhibitor in transient focal ischemia. (3/13910)

Both nitric oxide synthase (NOS) inhibitors and free radical scavengers have been shown to protect brain tissue in ischemia-reperfusion injury. Nitric oxide and superoxide anion act via distinct mechanisms and react together to form the highly deleterious peroxynitrite. Therefore the authors examined the effects and the interaction between the NOS inhibitor, NG nitro-L-arginine (LNA) and the antioxidant/superoxide scavenger, di-tert-butyl-hydroxybenzoic acid (DtBHB) in the rat submitted to 2 hours of middle cerebral artery occlusion. Posttreatment was initiated 4 hours after the onset of ischemia and infarct volume was measured at 48 hours. The dose-related effect of LNA resulted in a bell-shaped curve: 15, 56, 65, and 33% reduction of total infarct for 0.03, 0.1, 0.3, and 1 mg/kg (intravenously [IV]) respectively and 11% increase in infarct volume for 3 mg/kg (IV). Whereas DtBHB (20 mg/kg; intraperitoneally [IP]) was ineffective, the dose of 60 mg/kg produced 65% protection in infarct volume. The combination of a subthreshold dose of LNA (0.03 mg/kg; IV) and DtBHB (20 mg/kg; IP) resulted in significant reduction (49%) in infarct volume. These results show that LNA and DtBHB act synergistically to provide a consistent neuroprotection against ischemic injury when administered 4 hours after ischemia. This suggests that nitric oxide and free radicals are involved and interact in synergy in ischemia-reperfusion injury.  (+info)

Increased lipophilicity and subsequent cell partitioning decrease passive transcellular diffusion of novel, highly lipophilic antioxidants. (4/13910)

Oxidative stress is considered a cause or propagator of acute and chronic disorders of the central nervous system. Novel 2, 4-diamino-pyrrolo[2,3-d]pyrimidines are potent inhibitors of iron-dependent lipid peroxidation, are cytoprotective in cell culture models of oxidative injury, and are neuroprotective in brain injury and ischemia models. The selection of lead candidates from this series required that they reach target cells deep within brain tissue in efficacious amounts after oral dosing. A homologous series of 26 highly lipophilic pyrrolopyrimidines was examined using cultured cell monolayers to understand the structure-permeability relationship and to use this information to predict brain penetration and residence time. Pyrrolopyrimidines were shown to be a more permeable structural class of membrane-interactive antioxidants where transepithelial permeability was inversely related to lipophilicity or to cell partitioning. Pyrrole substitutions influence cell partitioning where bulky hydrophobic groups increased partitioning and decreased permeability and smaller hydrophobic groups and more hydrophilic groups, especially those capable of weak hydrogen bonding, decreased partitioning, and increased permeability. Transmonolayer diffusion for these membrane-interactive antioxidants was limited mostly by desorption from the receiver-side membrane into the buffer. Thus, in this case, these in vitro cell monolayer models do not adequately mimic the in vivo situation by underestimating in vivo bioavailability of highly lipophilic compounds unless acceptors, such as serum proteins, are added to the receiving buffer.  (+info)

Novel, highly lipophilic antioxidants readily diffuse across the blood-brain barrier and access intracellular sites. (5/13910)

In an accompanying article, an in vitro assay for permeability predicts that membrane-protective, antioxidant 2,4-diamino-pyrrolo[2, 3-d]pyrimidines should have improved blood-brain barrier (BBB) permeation over previously described lipophilic antioxidants. Using a first-pass extraction method and brain/plasma quantification, we show here that two of the pyrrolopyrimidines, one of which is markedly less permeable, readily partition into rat brain. The efficiency of extraction was dependent on serum protein binding, and in situ efflux confirms the in vitro data showing that PNU-87663 is retained in brain longer than PNU-89843. By exploiting inherent fluorescence properties of PNU-87663, its distribution within brain and within cells in culture was demonstrated using confocal scanning laser microscopy. PNU-87663 rapidly partitioned into the cell membrane and equilibrates with cytoplasmic compartments via passive diffusion. Although partitioning of PNU-87663 favors intracytoplasmic lipid storage droplets, the compound was readily exchangeable as shown by efflux of compound from cells to buffer when protein was present. The results demonstrated that pyrrolopyrimidines were well suited for quickly accessing target cells within the central nervous system as well as in other target tissues.  (+info)

Mechanisms and mediators in coal dust induced toxicity: a review. (6/13910)

Chronic inhalation of coal dust can cause several lung disorders, including simple coal workers pneumoconiosis (CWP), progressive massive fibrosis (PMF), chronic bronchitis, lung function loss, and emphysema. This review focuses on the cellular actions and interactions of key inflammatory cells and target cells in coal dust toxicity and related lung disorders, i.e. macrophages and neutrophils, epithelial cells, and fibroblasts. Factors released from or affecting these cells are outlined in separate sections, i.e. (1) reactive oxygen species (ROS) and related antioxidant protection mechanisms, and (2) cytokines, growth factors and related proteins. Furthermore, (3) components of the extracellular matrix (ECM), including the modifying role of ROS, cytokines, proteases and antiproteases are discussed in relation to tissue damage and remodelling in the respiratory tract. It is recognised that inhaled coal dust particles are important non-cellular and cellular sources of ROS in the lung, and may be significantly involved in the damage of lung target cells as well as important macromolecules including alpha-1-antitrypsin and DNA. In vitro and in vivo studies with coal dusts showed the up-regulation of important leukocyte recruiting factors, e.g. Leukotriene-B4 (LTB4), Platelet Derived Growth Factor (PDGF), Monocyte Chemotactic Protein-1 (MCP-1), and Tumor Necrosis Factor-alpha (TNF alpha), as well as the neutrophil adhesion factor Intercellular Adhesion Molecule-1 (ICAM-1). Coal dust particles are also known to stimulate the (macrophage) production of various factors with potential capacity to modulate lung cells and/or extracellular matrix, including O2-., H2O2, and NO, fibroblast chemoattractants (e.g. Transforming Growth Factor-beta (TGF beta), PDGF, and fibronectin) and a number of factors that have been shown to stimulate and/or inhibit fibroblast growth or collagen production such as (TNF alpha, TGF beta, PDGF, Insulin Like Growth Factor, and Prostaglandin-E2). Further studies are needed to clarify the in vivo kinetics and relative impact of these factors.  (+info)

Effects of pyrogallol, hydroquinone and duroquinone on responses to nitrergic nerve stimulation and NO in the rat anococcygeus muscle. (7/13910)

1. The hypothesis that endogenous superoxide dismutase (SOD) protects the nitrergic transmitter from inactivation by superoxide and that this explains the lack of sensitivity of the transmitter to superoxide generators was tested in the rat isolated anococcygeus muscle. 2. Responses to nitrergic nerve stimulation or to NO were not significantly affected by exogenous SOD or by the Cu/Zn SOD inhibitor diethyldithiocarbamic acid (DETCA). 3. Hydroquinone produced a concentration-dependent reduction of responses to NO with an IC50 of 27 microM, and higher concentrations reduced relaxant responses to nitrergic nerve stimulation with an IC50 of 612 microM. The effects of hydroquinone were only slightly reversed by SOD, so it does not appear to be acting as a superoxide generator. 4. Pyrogallol produced a concentration-dependent reduction in responses to NO with an IC50 value of 39 microM and this effect was reversed by SOD (100-1000 u ml(-1)). Pyrogallol did not affect responses to nitrergic nerve stimulation. Treatment with DETCA did not alter the differentiating action of pyrogallol. 5. Duroquinone produced a concentration-dependent reduction of relaxations to NO with an IC50 value of 240 microM and 100 microM slightly decreased nitrergic relaxations. After treatment with DETCA, duroquinone produced greater reductions of relaxant responses to NO and to nitrergic stimulation, the IC50 values being 8.5 microM for NO and 40 microM for nitrergic nerve stimulation: these reductions were reversed by SOD. 6. The findings do not support the hypothesis that the presence of Cu/Zn SOD explains the greater susceptibility of NO than the nitrergic transmitter to the superoxide generator pyrogallol, but suggest that it may play a role in the effects of duroquinone.  (+info)

UV-A-induced decrease in nuclear factor-kappaB activity in human keratinocytes. (8/13910)

Previous reports have demonstrated an increase in nuclear factor-kappaB (NF-kappaB) activity in response to UV radiation. These studies have essentially focused on the DNA-damaging fraction of solar UV radiation (UV-B and UV-C). In contrast, the effects of UV-A radiation (320-400 nm) on NF-kappaB are not well known. In this study, we present evidence that UV-A radiation induces a marked decrease in NF-kappaB DNA-binding activity in NCTC 2544 human keratinocytes. In addition, NCTC 2544 keratinocytes pretreated with UV-A fail to respond to NF-kappaB inducers. Moreover, UV-A radiation induces a decrease in NF-kappaB-driven luciferase reporter gene expression in NCTC 2544 keratinocytes. The expression of the gene encoding IkappaBalpha (IkappaB is the NF-kappaB inhibitor), which is closely associated with NF-kappaB activity, is also reduced (3-fold) upon UV-A treatment. Our results indicate that the UV-A-induced decrease in NF-kappaB DNA-binding activity is associated with a decrease in the levels of the p50 and p65 protein subunits. This is the first evidence that an oxidative stress, such as UV-A radiation, may induce a specific decrease in NF-kappaB activity in mammalian cells, probably through degradation of NF-kappaB protein subunits. These findings suggest that UV-A could modulate the NF-kappaB-dependent gene expression.  (+info)

Oxygen radical absorbance capacity (ORAC) is a method of measuring antioxidant capacities in biological samples in vitro. A wide variety of foods have been tested using this method, with certain spices, berries and legumes rated highly in extensive tables once published by the United States Department of Agriculture (USDA), but withdrawn in 2012 since no correlation between test results and biological activity could be determined, stating that no physiological proof in vivo existed in support of the free-radical theory. Although not all have been unilaterally dismissive, the majority position supports the USDA decision. Alternative measurements include the Folin-Ciocalteu reagent, and the Trolox equivalent antioxidant capacity assay. The assay measures the oxidative degradation of the fluorescent molecule (either beta-phycoerythrin or fluorescein) after being mixed with free radical generators such as azo-initiator compounds. Azo-initiators are considered to produce the peroxyl radical by ...
Background: Patients with end-stage renal disease undergoing hemodialysis (HD) are exposed to oxidative stress, which is associated with an impairment of antioxidant defense and an overproduction of oxidative stress markers. Oxidative stress plays a significant role in the development of inflammation in these patients. Objectives: The high incidence of cardiovascular diseases in HD patients is now well established and the involvement of oxidative stress has been hypothesized in these phenomena. This study focused on a comparison of plasma total antioxidant capacity (TAC) and lipid peroxidation product and evaluated the relationship between them and high-sensitivity C-reactive protein in patients on HD. Subjects and Methods: Plasma (TAC), lipid peroxidation products, malondialdehyde (MDA) as well as high-sensitivity C-reactive protein were determined in 30 patients on HD and in 20 normal controls (NC). Results: TAC and MDA levels were significantly higher in patients on HD than in the control ...

The test drink contained: 2 mg beta-carotene/100 ml, 40 mg alpha-tocopherol/100 ml, 80 mg ascorbic acid/100 ml, 2 mg pyridoxine/100 ml, 15 mg magnesium/100 ml, 0.2 mg manganese/100 ml, 1 mg zinc/100 ml, 0.1 mg copper/100 ml and 10 μg selenium/100 ml. Consumption of the test drink for 4 weeks increased the total plasma antioxidant capacity by 7% (ferric reducing ability of plasma method, P<0.05 compared with the placebo group), and the content of selenium and selenoprotein P in serum was raised by 16-17% (P<0.001 compared with the placebo group). No ...
A high intake of dietary antioxidant compounds has been hypothesized to be an appropriate strategy to reduce gastric cancer (GC) development. We investigated the effect of dietary total antioxidant capacity (TAC) in relation to GC in the European Prospective Investigation into Cancer (EPIC) study including 23 centers in 10 European countries. A total of 521,457 subjects (153,447 men) aged mostly 35-70 years old, were recruited largely between 1992 and 1998. Ferric reducing antioxidant potential (FRAP) and total radical-trapping antioxidant parameter (TRAP), measuring reducing and chain-breaking antioxidant capacity were used to measure dietary TAC from plant foods. Dietary antioxidant intake is associated with a reduction in the risk of GC for both FRAP (adjusted HR 0.66; 95%CI (0.46-0.95) and TRAP (adjusted HR 0.61; 95%CI (0.43-0.87) (highest vs. lowest quintile). The association was observed for both cardia and noncardia cancers. A clear effect was observed in smokers with a significant reduction in

The aim of this research was to test the correctness of response of a superoxide dismutase amperometric biosensor used for the purpose of measuring and ranking the total antioxidant capacity of several systematically analysed mixed berries. Several methods are described in the literature for determining antioxidant capacity, each culminating in the construction of an antioxidant capacity scale and each using its own unit of measurement. It was therefore endeavoured to correlate and compare the results obtained using the present amperometric biosensor method with those resulting from two other different methods for determining the total antioxidant capacity selected from among those more frequently cited in the literature. The purpose was to establish a methodological approach consisting in the simultaneous application of different methods that it would be possible to use to obtain an accurate estimation of the total antioxidant capacity of different mixed berries and the food products containing them.
Fresh human milk has a higher antioxidant capacity than infant formula. This result is consistent with the study of Shoji et al,10 who found increased urinary 8-hydroxy-2′-deoxyguanosine excretion in formula fed infants compared with breast fed infants. Schwarz et al11 found similar results by measuring breath ethane concentrations in breast fed and formula fed infants. Although most studies showed that human milk had a higher antioxidant capacity than formula, one study by Alberti-Fidanza et al12 using the oxygen radical absorbance capacity assay, suggested that formula may have higher antioxidant capacity than human milk. The difference in these findings may be due to the different methods used to determine the antioxidant capacity of human milk. An improved oxygen radical absorbance capacity assay has been developed and validated using fluorescein.13,14 Friel et al15 showed that human milk has better antioxidant protection than formulas, perhaps because of the higher iron content of ...

This study was designed to elucidate the effect of ascorbic acid on salivary total antioxidant capacity in smokers. In this single blind crossover clinical trial, the whole unstimulated saliva of 30 smokers, who were randomly divided into two groups, was collected. In the first phase after the saliva collection, one group of patients took 500 mg of vitamin C powder, for 3 weeks. Then, saliva of all patients was collected. After a one-week wash-out period, vitamin C was given to the other group. The collection of saliva was done after 3 weeks. Total antioxidant capacity was measured. Statistic evaluation was performed by Repeated Measured ANOVA, Independent sample t-test and Covariate test. The mean of total antioxidant capacity with and without using vitamin C was 0.511 ± 0.155 (U/mL) and 0.555 ± 0.171 (U/mL), respectively. This variability was not significant (p = 0.605). Oxidative stress from cigarette smoke was not decreased significantly with using vitamin C.

If your goal is to get a glowing skin tone, end clogged pores, and end acne once and for all, then antioxidants are a goldmine.. Supercharging your bodily antioxidant supplies is the joint most effective strategy for acne. Overall, it is one of the most enjoyable ways to clear acne too. Your near infallible rule is that the more flavoursome the fruit or herb, the heavier and more diverse the antioxidant count.. That said, theres a common perception that plant foods are the only source of antioxidants, which is wrong. A banana, for example, contains only a few antioxidants, like rutin. Meanwhile a slab of beef, not associated with antioxidants in adverts, is drenched in minerals and aids your body in manufacturing its own antioxidants.. The antioxidant content of a food does not totally determine the end result in your bloodstream and skin. To give you an easily consultable list for rapid action, here are 23 foods with strong powers to increase bodily antioxidant levels, and hence strong powers ...

The objective of this study was to determine whether running a 24-h race would cause oxidative damage and changes in the blood antioxidant defense capacity in endurance-trained athletes. Fourteen male amateur runners (mean age 43.0±10.8 y, body weight 64.3±7.2 kg height 171±5 cm, weekly covered distance 81±43 km, training history 8±9 y) who participated in a 24-hr ultra-marathon and volunteered to give blood samples during the race were enrolled for this study. Blood samples were taken before the run, after completing the marathon distance (42.217 km), after 12 h and at the conclusion of the race.The capacity of erythrocyte antioxidant defense system was evaluated by measuring the activities of superoxide dismutase (SOD), glutathione peroxidase (GPX), catalase (CAT), glutathione reductase (GR), concentrations of non-enzymatic antioxidants (uric acid and glutathione-GSH), and selected biomarkers of oxidative stress (i.e., plasma level of malondialdehyde (MDA) and plasma antioxidant capacity ...
If this recipe for Antioxidant Shooters has caught your eye, I have a feeling you are aware that pomegranate juice, strawberries and blueberries are filled with antioxidants. With the addition of beets, this recipe is SUPER high in antioxidants. If you dont have time to cook beets, you can often find them on the salad bar at a high end or gourmet grocery store. What is interesting about beets is not the fact that they are rich in antioxidants, but the unusual mix of antioxidants that they contain. Beets have unique antioxidants since they get their red color primarily from betalain antioxidant pigments (and not primarily from anthocyanins). This combined with being a very good source of the antioxidant manganese and vitamin C, provides antioxidant support in a different way than other antioxidant-rich vegetables.. Have you heard the term but wonder why antioxidants are important? Antioxidants offer a number of health benefits and can help possibly prevent diseases, ranging from cancer to ...
Among the fruits specifically highlighted as beneficial were grapes, which, after consumption resulted in almost double the amount of recommended total antioxidant capacity needed to counteract the deficit associated with consuming 1000 calories of food.. Dr. Ronald L. Prior of the USDAs Arkansas Childrens Nutrition Center, widely recognized as a pioneer of the ORAC (Oxygen Radical Absorbance Capacity) technique for measuring antioxidant capacity in foods, shared his findings regarding the natural state of oxidative stress in the body that results from eating a meal and the ability to counteract it in humans following consumption of certain fruits.. Prior showed that the metabolic process of digesting a meal with no antioxidants -- just fat, carbohydrate and protein -- causes a decline in antioxidant capacity of the blood which creates a temporary state of oxidative stress. This deficit can be prevented by consuming high antioxidant fruits such as grapes, which in this study provided almost ...

Different kinds of antioxidants. Antioxidants are types of nutrients and enzymes that can help promote health and may play a role in reducing your risk of chronic illnesses. They do this by combatting the free radicals produced as a result of oxidation.. Not all forms of antioxidants are the same. In fact, there are different types. Antioxidants can be soluble (i.e. they dissolve) in either water or in fat. Both types of antioxidants are important, as they can both be attacked by free radicals.. Water soluble antioxidants include vitamin C and polyphenols (antioxidants specifically from plants), whereas fat soluble antioxidants include vitamin A, vitamin E, carotenoids and lipoic acid.. Can Oxidative Stress be prevented?. Some of the effects of oxidative stress can be counteracted. Your body is unlikely to produce enough antioxidants to fight all the free radicals, so you can do your bit to support it. Trying to avoid some of the causes of free radicals may be beneficial, as well as eating a ...
The purpose of this study was to characterize the antioxidant content of honey from 10 different floral sources (sage, orange, tupelo, manuka, buckwheat, acacia, fireweed, clover, Hawaiian Christmasberry, and soy) and determine their effects on growth of selected oral pathogens (e.g., Steptococcus mutans, Porphyromonas gingivalis, Actinobacillus actinomycetemcomitans, Fusobacterium nucleatum). Antioxidant capacity of the honeys was determined via the oxygen radical absorbance capacity (ORAC) assay. Specific antioxidant components including phenolics and ascorbate were determined via HPLC analysis. ORAC values ranged from 3 -17 mmol Trolox equivalent/g honey. A linear correlation was observed between total phenolic content and ORAC activity (R2= 0.9352). Antioxidant capacity of the honeys appeared to be due primarily to their phenolic composition as opposed to enzymatic antioxidants and ascorbic acid. Although all 10 honeys were not effective at inhibiting growth of S. mutans, selected components ...
Shelf life of cooked ground beef links with no, low, or high concentrations of a blend of natural plant extract antioxidant were compared to evaluate lipid oxidation over time. When no antioxidants were added, samples stored nine days or beyond were more oxidized than the samples with the addition of an antioxidant. No differences in lipid oxidation were observed between 0.13% and 0.20% antioxidant concentrations during similar days of refrigerated storage days. Therefore, the addition of natural antioxidants were effective at reducing oxidative rancidity, regardless the concentration of antioxidant.

Previous observations have indicated that the red peel areas of grapefruit with high lycopene concentrations were more tolerant to CI than yellow peel areas (Lado et al., 2015a). Because lycopene is a carotene with powerful antioxidant capacity, this study investigated whether the CI tolerance of the lycopene-accumulating rind of grapefruit may be due to an enhancement of the enzymatic and/or nonenzymatic antioxidant systems. Total antioxidant capacity, antioxidant metabolite (GSH and AsA) contents, and antioxidant enzyme (GR [glutathione reductase], ascorbate peroxidase [APX], catalase [CAT] and superoxide dismutase [SOD]) activity and gene expression were measured in the peel of Star Ruby grapefruit with contrasting CI tolerance during storage at 2 C for up to 58 d. The peel of CI-tolerant fruit exhibited a lower lipid peroxidation level (MDA content). The hydrogen peroxide concentration was similar after 3 weeks of storage, when the differences in chilling damage between sensitive and ...
The antioxidant capacity and the phenolic content of hydroalcoholic macerations from leaves, inflorescences, stems and roots of species of the genus Pluchea were also compared. Leaf extracts followed by inflorescence extracts showed the highest values of antioxidant capacity. The species P. carolinensis was used as a model to evaluate the antioxidant capacity in two locations and two phenological stages and also for monitoring the antioxidant capacity over some months. Natural adult specimens presented a higher phenolic content, as well as higher antioxidant capacity than young and cultivated specimens. Maximal antioxidant capacity and concentrations in phenolics were recorded in January, September and December; over the blooming stage (March), the antioxidant capacity was minimal. Two different solvents of extraction and two methods were also screened for extracting the maximal concentrations in antioxidants. Hydroalcoholic extractions showed higher antioxidant capacity than ethanolic ones. ...
On the other hand, vitamin C did not have an effect on mortality and the antioxidant mineral selenium was associated with a nine per cent decrease in all-cause mortality. "We could find no evidence to support taking antioxidant supplements to reduce the risk of dying earlier in healthy people or patients with various diseases,"​ said Goran Bjelakovic from the Copenhagen Trial Unit at the Copenhagen University Hospital in Denmark. A republishing of last years antioxidant meta-analysis in the prestigious Cochrane Systematic Review​ today looks set to refocus attention on the efficacy of antioxidant supplements, and raise questions over their safety. The meta-analysis was originally published in the Journal of the American Medical Association​ (2007, Vol. 297, pp. 842-857) last year and attracted criticism from both inside and outside of the dietary supplements industry. The authors admit that this report contained errors and corrections were subsequently published in JAMA​ (2008, Vol. ...

Seventytwo Indian barley varieties were screened for their antioxidant activity for 2 years using two antiradical systems Differences in the levels of antioxidant activity in 2 years were obtained but the genotypic differences still remained and a 2fold variability was observed in the antioxidant activity Yeartoyear differences were also obtained when the selected varieties were analyzed for their free and bound phenolic contents Evaluation of the antioxidant activity and phenolic content in the five varieties grown at six different locations revealed that the antioxidant activity and the free phenolics were more influenced by the genotype whereas the bound and the total phenolics were most influenced by the environment After malting no significant changes were observed in the antioxidant activity however a 2fold increase was observed in the total phenolic content which was mainly due to the increase in the level of free phenolics after ...
1. The oxidation of low-density lipoprotein (LDL) is believed to play a central role in atherogenesis. We have compared the effect of antioxidant vitamins and high-density lipoprotein (HDL) on the Cu(2+)-catalysed oxidation of LDL. 2. Antioxidant vitamin supplementation significantly reduced conjugated diene formation but did not affect the formation of lipid peroxides. 3. Conversely, HDL did not affect conjugated diene formation but inhibited the formation of lipid peroxides by up to 90%. 4. The inhibition by HDL of lipid peroxide formation in oxidized LDL was dependent on the concentration of HDL and was not due to HDL chelating Cu2+. 5. Large interindividual variations in the inhibition of lipid peroxide formation by autologous HDL were evident, which were related to the rate of lipid peroxide generation in the LDL. 6. We conclude that HDL is a powerful antioxidant or more probably inhibitor of LDL oxidation in vitro and may play an important role in vivo in preventing atherosclerosis by ...
Youve seen or heard the term antioxidant before and you feel like its something you should have in your food, right? Right, but you probably dont know what antioxidants actually are and why you need them. I know that was the case for me.. To understand what antioxidants are, you must first know what a free radical is. Free radicals are naturally occurring substances in our bodies that attack the fats, protein and DNA in our cells, causing us to age quickly and can even cause diseases. Antioxidants are the compounds found in some foods that help to neutralize the free radicals in our bodies. The best sources of antioxidants are fruits and vegetables but they are also found in green tea, black tea, red wine and dark chocolate (yum!). According to experts, the presence of color indicates that there is a specific antioxidant in that food.. Now do you understand why we need them? I do! To get a healthy dose of antioxidants in your diet, try eating more of these foods.. Tomatoes ...
BACKGROUND & AIMS: Chronic inflammation impairs recovery among the 1.6 million people who suffer from hip fracture annually. Vitamin E and the carotenoids are two classes of dietary antioxidants with profound anti-inflammatory effects, and the goal of this study was to assess whether higher post-fracture concentrations of these antioxidants were associated with lower levels of interleukin 6 (IL-6) and the soluble receptor for tumor necrosis factor-alpha (sTNF-αR1), two common markers of inflammation. METHODS: Serum concentrations of the dietary antioxidants and inflammatory markers were assessed at baseline and 2, 6, and 12 month follow-up visits among 148 hip fracture patients from The Baltimore Hip Studies. Generalized estimating equations modeled the relationship between baseline and time-varying antioxidant concentrations and inflammatory markers. RESULTS: Higher post-fracture concentrations of vitamin E and the carotenoids were associated with lower levels of inflammatory markers. ...

Extensive evidence has demonstrated that many antioxidants such as vitamin C, vitamin E, carotenoids and polyphenols have protective effects in preventing cardiovascular disease (CVD), a chronic disease that is mediated by oxidative stress and inflammation. This review focuses on evidence from prospective cohort studies and clinical trials in regard to the associations between plasma/dietary antioxidants and cardiovascular events. Long-term, large-scale, population-based cohort studies have found that higher levels of serum albumin, bilirubin, glutathione, vitamin E, vitamin C, and carotenoids were associated with a lower risk of CVD. Evidence from the cohort studies in regard to dietary antioxidants also supported the protective effects of dietary vitamin E, vitamin C, carotenoids, and polyphenols on CVD risk. However, results from large randomized controlled trials did not support long-term use of single antioxidant supplements for CVD prevention due to their null or even adverse effects on major
Natures Cellular Protection. Research has shown that many degenerative diseases are the direct result of free radical damage in the body. Free radicals are considered a major component in aging and disease progression. The destruction of healthy cells may easily be avoided by adding powerful antioxidant nutrients to your daily diet.. The antioxidant combination in Radical Fruits™ has potent immune-enhancing properties. An extensive ORAC analysis (Oxygen Radical Absorbance Capacity) performed at Tufts University in Boston, showed high scores in the ability of these fruit extracts to significantly protect cells and their components from oxidative damage. They were also shown to help slow the processes associated with aging in both body and brain function. High ORAC foods have been found to raise the antioxidant capacity of human blood 10-25%, helping to increase learning ability and prevent the loss of long-term memory.. Due to their superior bio-availability, the concentrated fruit extracts in ...
I was researching antioxidants and found this info (from wikipedia):. "Potential of antioxidant supplements to damage health. There is evidence that antioxidant supplements promote disease and increase mortality in humans.[81][82] It was previously proposed on a hypothetical basis that free radicals may induce an endogenous response culminating in more effective adaptations which protect against exogenous radicals (and possibly other toxic compounds).[83] Recent experimental evidence strongly suggests that this is indeed the case, and that such induction of endogenous free radical production extends the life span of Caenorhabditis elegans.[84] Most importantly, this induction of life span is prevented by antioxidants, providing direct evidence that toxic radicals may mitohormetically exert life extending and health promoting effects.[81][82]". ...So it looks as if antioxidants may actually suppress your bodies natural ability to produce its own antioxidants. Antioxidants do suppress disease and ...
There are several nutrients in food that contain antioxidants. Vitamin C, vitamin E, and beta carotene are among the most commonly studied dietary antioxidants. Vitamin C is the most important water-soluble antioxidant in extracellular fluids. Vitamin C helps to neutralize ROS in the water or aqueous phase before it can attack the lipids. Vitamin E is the most important lipid soluble antioxidant. It is important as the chain-breaking antioxidant within the cell membrane. It can protect the membrane fatty acids from lipid peroxidation. Vitamin C in addition is capable of regenerating vitamin E.. Beta carotene and other carotenoids also have antioxidant properties. Carotenoids work in synergy with vitamin E. ...
The antioxidant properties of the synthetic compound (C1)-(C8), which comprised 7 curcuminoids and a chalcone, were evaluated by two complementary assays, DPPH and β-carotene/linoleic acid. It was found that, in general, the free radical scavenging ability of (C1)-(C8) was concentration-dependent. Compounds (C1) and (C4), which contained (4-OH) phenolic groups, were found to be highly potent antioxidants with higher antioxidant values than BHT suggesting that synthetic curcuminoids are more potent antioxidants than standard antioxidants like BHT. Using β-carotene-linoleic acid assay, only the water-soluble 2, 4,6-trihydroxyphenolic chalcone (C5) showed 85.2 % inhibition of the formation of conjugated dienes reflecting on its potent antioxidant activity.. ...
Mitochondrial antioxidant genes are major regulators of oxidative stress in the vasculature. Previous data has shown that reducing antioxidant capacity accelerates atherosclerotic plaque size, however, it is unclear whether reducing mitochondrial antioxidant capacity alters plaque composition. Therefore, we tested the hypothesis that reductions of mitochondrial antioxidant capacity will increase osteogenic markers and intimal plaque calcification in aorta from hypercholesterolemic mice. We used Ldlr-/-ApoB100/100 (LA) mice that were either wild-type (LA-MnSOD+/+) or heterozygous (LA-MnSOD+/-) for manganese superoxide dismutase that were fed a Western Diet (TD88137) for 3 or 6 months. Changes in changes gene expression were assessed in aortic arch using qRT-PCR, plaque calcium levels were examined using histological evaluation from aortic cryosections, and endothelial function was measured using isolated organ bath chambers (ex vivo). While expression of SP7 (an osteogenic transcription factor) ...

Dehydrated apples, apricots, and plums have more antioxidants than their fresh equivalents. Pick unsweetened ones as the fruits are quite sugary ...
AntiOxidant Formula Protection against free radicals Supplementation with antioxidants such as vitamins C and E has been growing rapidly in the past few years as research on harmful free radicals intensifies. Free radicals are atoms, ions, or molecules with one or more unpaired electrons that bind to and destroy cellular compounds. Dietary antioxidants disarm free radicals through a number of different mechanisms. Foremost, they bind to the free electrons, pairing up with them, creating an innocuous cellular compound that the body can eliminate as waste. The antioxidants in this formula also support and enhance the bodys natural defense mechanisms against free radicals: the enzymes superoxide dismutase, catalase, and glutathione peroxidase. Recent research points to the fact that a synergistic combination of antioxidants is more effective than the total effect of each antioxidant taken alone. AntiOxidant Formula offers a synergistic, broad spectrum of antioxidants designed to protect
A number of analytical methods exist for the evaluation of oxidative stress. Some of these directly measure the accumulation of oxidizing species or of oxidized products, while other methods measure the defence capacity of the organism against oxidation, which is referred to as the specific or the total antioxidant capacity (TAC). Amongst these TAC methods, TEAC (Trolox Equivalent Antioxidant Capacity) assays which involve the use of radicals of compounds such as N,N-dimethyl-p-phenylenediamine (DMPD) or 2,2’-azinobis(3- ethylbenzothiazoline-6-sulphonic acid) (ABTS), have attracted the attention of biochemists and analysts due to their operational simplicity. These methods are based upon the spectrophotometric measurement of the antioxidant activity of body fluids, herbal extracts, fruits, vegetables and other food samples and have certain limitations with regard to their application range, stability and environmental fate. In the present study we have improved upon the ...
Oxidative stress occurs when oxygen free-radicals outnumber antioxidants in the body, leading to inflammation that damages cell proteins, fats and DNA. In coronary artery disease (CAD), blood vessels thicken and narrow, and doctors in one study said oxidative stress and inflammation play a central role. In the study, 51 people with advanced CAD took 60 mg of CoQ10 per day, 150 mg per day or a placebo. Coenzyme Q10, or ubiquinone, is a powerful antioxidant that helps produce energy in every cell in the body.. After 12 weeks, while there was no significant change in the placebo or 60 mg groups, those who took 150 mg of CoQ10 had 29 percent lower levels of oxidative stress and a large increase in protective antioxidant enzyme activity.. Doctors concluded CoQ10 may promote rapid and sustainable antioxidation in CAD.. ...
Background This study was aimed to examine circadian variations of hepatic antioxidant components, including the Nrf2- pathway, the glutathione (GSH) system, antioxidant enzymes and metallothionein in mouse liver. Methods and Results Adult mice were housed in light- and temperature-controlled facilities for 2 weeks, and livers were collected every 4 h during the 24 h period. Total RNA was isolated, purified, and subjected to real-time RT-PCR analysis. Hepatic mRNA levels of Nrf2, Keap1, Nqo1 and Gclc were higher in the light-phase than the dark-phase, and were female-predominant. Hepatic GSH presented marked circadian fluctuations, along with glutathione S-transferases (GST-α1, GST-µ, GST-π) and glutathione peroxidase (GPx1). The expressions of GPx1, GST-µ and GST-π mRNA were also higher in females. Antioxidant enzymes Cu/Zn superoxide dismutase (Sod1), catalase (CAT), cyclooxygenase-2 (Cox-2) and heme oxygenase-1 (Ho-1) showed circadian rhythms, with higher expressions of Cox-2 and CAT in
Paraoxonase 1 (PON1) activity is markedly influenced by coding polymorphisms, Q/R at position 192 and M/L at position 55 of the PON1 gene. We investigated the frequencies of these polymorphisms and their effects on PON1 and antioxidant activities in 844 South African mixed ancestry individuals. Genotyping was done using allele-specific TaqMan technology, PON1 activities were measured using paraoxon and phenylacetate, oxidative status was determined by measuring the antioxidant activities of ferric reducing antioxidant power and trolox equivalent antioxidant capacity, and lipid peroxidation markers included malondialdehyde and oxidized LDL. The frequencies of Q192R and L55Mwere 47.6% and 28.8%, respectively, and the most common corresponding alleles were 192R (60.4%) and 55M (82.6%).The Q192 was significantly associated with 5.8 units increase in PON1 concentration and 15.4 units decrease in PONase activity after adjustment for age, sex, BMI, and diabetes, with suggestion of differential ...
Cardiovascular disease (CVD) is the leading cause of Taiwan. L-carnitine (LC) and coenzyme Q10 is recognized as lipid soluble antioxidants. The purposes of this study are going to investigate the relation of LC and coenzyme Q10 with the markers of lipid peroxidation, antioxidant enzymes activities, and the inflammatory markers in coronary artery disease (CAD) patients. The study is designed as a three-year study. The first year is an observation study. We will recruit CAD patients who are identified by cardiac catheterization as having at least 50% stenosis of one major coronary artery, and age-gender matched healthy subjects.

Antioxidants. Youve heard about them everywhere along with how great they are for your body but what exactly are they and where can you find them? What are free radicals, how are we exposed to them, how do they affect the body? What can antioxidants do for your body then? Antioxidants fight free radicals and oxidative stress that free radicals can cause (get it? Antioxidant is essentially anti-oxidative stress). While our body has natural antioxidant defenses, eating a diet abundant in antioxidants can further help fight these free radicals that can cause illnesses. Read more about antioxidants and free radicals ...
Attempts to gain a longer life span by boosting protection against this slowly rising free radical damage process were done by adding to the diet EXOGENOUS (not produced in the body) antioxidants. These attempts have largely been failures. This was tried by adding natural antioxidants like Vitamins C, E, and a group of plant compounds called carotenoids (red to yellow colored plant pigments that intercept specific types of free radicals). After this failure, far stronger EXOGENOUS antioxidants were tried in the same process with the similar results. What was gained by these high antioxidant experiments was a realization that many of the diseases of aging were pushed further out in time, but life spans were not increased. We need to get enough antioxidants to prevent needless damage and also to put off as much as possible needless diseases of age. As we will learn later in the LONGEVITY section , the combination of antioxidants and natural anti-inflammatories is a much better approach. After many ...

It is widely accepted that cyanobacteria-dependent oxygen that was released into Earths atmosphere ca. 2.5 billion years ago sparked the evolution of the aerobic metabolism and the antioxidant system. In modern aerobes, enzymes such as superoxide dismutases (SODs), peroxiredoxins (PXs), and catalases (CATs) constitute the core of the enzymatic antioxidant system (EAS) directed against reactive oxygen species (ROS). In many anaerobic prokaryotes, the superoxide reductases (SORs) have been identified as the main force in counteracting ROS toxicity. We found that 93% of the analyzed strict anaerobes possess at least one antioxidant enzyme, and 50% have a functional EAS, that is, consisting of at least two antioxidant enzymes: one for superoxide anion radical detoxification and another for hydrogen peroxide decomposition. The results presented here suggest that the last universal common ancestor (LUCA) was not a strict anaerobe. O2 could have been available for the first microorganisms before ...

The major finding of the study is that long-term oral Rg1 supplementation can strengthen antioxidant defense capability in skeletal muscle and attenuate the oxidative damage induced by an acute bout of exhaustive exercise. In particular, exhaustive exercise-induced membrane lipid peroxidation was effectively eliminated in the skeletal muscle of rats, which pre-treated with Rg1. In line with this finding, decreased GSH/GSSG ratio after exercise was prevented in the Rg1 group. These results provide compelling evidence that oral Rg1 supplementation can protect sarcolemma against exercise-induced oxidative stress by enhancing antioxidant system of skeletal muscle.. Minimizing of unwanted side reactions like lipid peroxidation and protein oxidation is essential in preserving normal function of cells, since all chemical reactions in human cells are under strict enzymatic regulation to conform a tightly controlled metabolic program. These are largely relying on maintaining normal structure of ...
The beneficial health effects attributed to the consumption of fruits and vegetables are related, at least in part, to their antioxidant activity.12 Edible plants contain several hundred different antioxidants.3 Natural antioxidants include vitamins C and E, carotenoids (such as P-carotene and tomatos lycopene), and polyphenolic fla-vonoids (such as those present in grapes, berries, licorice, ginger, nuts, and olive oil).. For a compound to be defined as an antioxidant it must satisfy two basic conditions:. 1. When present at low concentration relative to the substrate to be oxidized, it can delay, retard, or prevent autooxidation or free radical-mediated oxidation.. 2. The resulting radical formed after scavenging must be stable in order to interrupt the oxidation chain reaction.. Low-density lipoprotein (LDL) oxidation is considered to be a hallmark of early atherogenesis. Nutritional antioxidants can affect LDL oxidation directly or indirectly, via modulations of arterial wall cell oxidative ...
The latest scientific standard for measuring the antioxidant properties of food is in ORAC (Oxygen Radical Absorbance Capacity) units. ORAC measures the total antioxidant capacity of a food or nutrient and can help us to understand its antioxidant strength. For example, a serving of PhytoBerry has an approximate ORAC score of 5,000 units. While in general terms the higher the ORAC score the greater the protection, ORAC only tells part of the story.. You also have to understand that our individual organs and internal systems have unique antioxidant requirements. Often times an organ is best protected by a botanical nutrient that may have a modest ORAC score. A higher ORAC nutrient that is less supportive of that organ may have a higher score but will not be able to offer the same level of protection. PhytoBerry does have an exceptional ORAC score, but its primary focus is to offer whole body antioxidantprotection by using a harmonized and synergistic combination of nutrients that, in concert, ...
Abstract. Authors: Fenercioglu AK, Saler T, Genc E, Sabuncu H, Altuntas Y.. BACKGROUND:. The hyperglycemia-induced oxidative stress in diabetes mellitus (DM) is the major factor in the pathogenesis of cardiovascular complications. The phenolic compounds are potent antioxidants that can reverse the factors leading to cardiovascular complications in DM. The aim of this study was to determine the antagonizing effects of a polyphenol-rich antioxidant supplement containing pomegranate extract, green tea extract, and ascorbic acid, on oxidative stress in Type 2 diabetic patients.. MATERIALS AND METHODS:. A total of 114 male and female non-smokers (56 study, 58 placebo) with Type 2 DM and without any complications were recruited. The blood levels of fasting blood glucose, glycated hemoglobin, LDL, HDL, triglycerides, plasma malondialdehyde (MDA), total glutathione (GSH), hydrogen peroxide, and antioxidant capacity (AOC) were determined at the beginning and at the end of the 3-month trial. The ...
This study shows that increases in oxidative stress, PKC activation, and NO production remain elevated for at least 12 months in retinas of diabetic or galactosemic animals and can be inhibited significantly by the administration of antioxidants. Moreover, our results indicate that administration of antioxidants can inhibit the development of diabetes-induced retinal histopathology. The results demonstrate that there is at least a strong association between hyperglycemia-induced oxidative stress and retinal histopathology.. Possible sources of oxidative stress in diabetes include increased generation of reactive oxygen species by auto-oxidation of glucose, decreased tissue concentrations of low-molecular-weight antioxidants (13,27,28,29), and impaired activities of antioxidant defense enzymes (13). We reported previously that retinal glutathione levels are decreased and antioxidant defense enzymes are impaired in diabetes and that these defects are corrected by supplementation with either ...

Oxidative stress has been considered as a potential pathogenic mechanism for initiation and progression of atherosclerotic disease. Excessive production of reactive oxygen species, a mediator of the oxidative stress cascade, leads to release of inflammatory cytokines, oxidation of LDL and prothrombotic state, and finally results in endothelial dysfunction and atherosclerotic vascular lesions. Adequate dietary, enzymatic and nonenzymatic antioxidant supplementation may be effective in lowering oxidative stress. Although most trials with antioxidants in experimental models of atherosclerosis have demonstrated that this treatment is able to retard the progression of atherosclerosis, the results of clinical trials are equivocal. Differences in the definition criteria of patients who are potential candidates for antioxidant treatment, type and dosage of antioxidant supplementation, as well as outcome measures may explain this variability. Since oxidative stress is activated by many cardiovascular ...

Obviously these laboratory measures do not tell us which products will work best to prevent disease. They do give us some perspective though on the various label and advertising claims we are confronted with.. Theres a second paper of interest related to this, also from 2008. In this paper Chinese researchers gave 26 people a daily glass of either apple juice or pomegranate juice and tested the blood of the test subjects to compare effects of the two juices. They measured changes in plasma antioxidant capacity, activity of antioxidant enzymes, contents of ascorbic acid, vitamin E, reduced glutathione, malondialdehyde, oxidized low-density lipoprotein and carbonyls, and the degree of DNA damage in mononuclear blood cells. Those who drank the pomegranate juice had a significantly higher plasma antioxidant capacity. The apple juice also had benefit but much less. The blood levels of vitamins C and E and other chemical antioxidants were not particularly different between the two groups of test ...
The study followed 2876 couples with 34 live trials performed. It included a placebo group, a no treatment group, and an antioxidant supplementation group for the men. There was a statistically significant increase in both pregnancies and live births in the antioxidant group.. In a world filled with pharmaceuticals that can create possible side effects, this particular study found there to be no side effects associated with the increased supplementation. It is always best to check with the trusted health care provider before beginning any new supplementation program. Certain supplements need to be taken in proper dosage and cross-checked with any other medication that the individual is taking.. Antioxidants can be found in food or through supplementation. They can help prevent oxidative stresses in our environment and from the lifestyle choices that we make each day. It is recommended to get antioxidants from food as much as possible by eating a variety of fruits and vegetables from all of the ...
Youve probably seen antioxidant labels on foods and supplements, but what does it mean exactly and what is the best antioxidant to choose? Antioxidant means it prevents oxidation, a process that happens to all cells in nature, including those in the human body. Oxidation happens when oxygen interacts with cells and its what makes an apple turn brown, metal rust, or food go rotten. In the body oxidation is a normal part of cell turnover. However, a small minority of oxidized cells become problematic "free radicals" that set off a chain reaction of damage, causing cells to mutate and behave abnormally. Free radicals reach us through pesticides, air pollution, cigarette smoke, excess alcohol, sunburn, junk foods, etc.. The defense? Antioxidants. And our most powerful antioxidant is one the body makes called glutathione. To stay a step ahead of modern civilization we need to avoid free radicals as much as possible, eat an antioxidant-rich diet, and make sure our body is sufficient in ...
Drink lots of juice? Eat plenty of vegetables? Take a daily multivitamin, plus extra C, E, and beta-carotene? You may think you are getting all the antioxidants you need. But youre probably not taking in the right ones, according to Lester Packer, Ph.D., professor of molecular and cell biology at the University of California, Berkeley, and a leading antioxidant researcher. In his new book The Antioxidant Miracle, Dr. Packer identifies five specific antioxidants he says are key to obtaining maximum protection against cancer, heart disease, cataracts, Alzheimers, and other ravages of age. Two of them youre probably familiar with: vitamin C and vitamin E. The others, coenzyme Q10, alpha-lipoic acid, and glutathione, are less well known. Scientists have known for years that hundreds of compounds act as antioxidants. Some are found in foods, others produced by the body. Antioxidants work their magic by counteracting free radicals, naturally occurring molecules that can damage cells and eventually ...

Food Chemistry. 164:510-517. Interpretive Summary: Antioxidants are nutritionally beneficial compounds in many foods. We compared different methods of preparing fresh corn with respect to their effect on antioxidant content. We found that steaming is better than boiling and leaving kernels on the cob is better than removing them from the cob in terms of the level of antioxidants retained in the final food product. The cooking water used to prepare blue corn is a rich source of antioxidant and may be a valuable co-product of corn preparation. The results of this study indicate how to prepare fresh corn with optimal nutritional quality. Technical Abstract: Antioxidant components, including anthocyanins and phenolic compounds, antioxidant activity, and their changes during traditional cooking of fresh ...

Spices have more antioxidant power, measure for measure, than fruits and vegetables. Antioxidants help prevent cancer, Alzheimers disease, heart disease, and premature aging. In a study reported in the British Journal of Nutrition, fifteen aromatic herbs and spices consumed in Central Italy as part of the Mediterranean diet were studied to reveal total phenolic, flavonoid and flavanol content as well as their antioxidant potential as measured by oxygen radical absorbance capacity (ORAC). Comparison was made between salads to which aromatic herbs had been added. The addition of lemon balm and marjoram increased by 150% and 200% respectively the antioxidant capacity of a salad portion, corresponding to an intake of 200 mg. of phenolics and 4000 ORAC units. Among other spices tested, cumin and fresh ginger made the most significant contribution to antioxidant capacity ...
Dole Nutrition Institute Research Uncovers Antioxidant Pathway Most people know the word "antioxidant" but new research from the Dole Nutrition Institute has uncovered that we may not know exactly how they work. DNI scientists investigated antioxidant capacity of fruits and vegetables and how different components of plants may influence health, revealing significant and somewhat surprising conclusions. Results have now been published in the Journal of Nutrition.. Antioxidants in foods are conventionally thought to act by trapping free radicals, highly reactive molecules that can have damaging effects in the body. Traditionally, antioxidants have been measured by oxygen radical absorption capacity (ORAC score), a laboratory index of the potential for a food to furnish antioxidant value in a test tube, or total phenolics content, a method which identifies specific structures of polyphenols in a food. However, DNI research finds these methods do not tell the whole story. Many healthful plant ...

A P P L I C AT I O N N O T E Liquid Chromatography Author: Wilhad M. Reuter PerkinElmer, Inc. Shelton, CT Analysis of Phenolic Antioxidants in Edible Oil/Shortening Using the PerkinElmer Altus UPLC System with PDA Detection Introduction Phenolic antioxidants are commonly used in food to prevent the oxidation of oils. Oxidized oil and fats cause foul odor and rancidity in food products, which is a major cause for concern to the food industry. Globally, regulations vary, but current maximum allowable levels are as low as 100 µg/g (100 ppm). This application note presents a UHPLC method for the analysis of the ten most common phenolic antioxidants that may be found in such products. The application was carried out with minor modifications to the AOAC Official Method 983.15 (1). This method applies to the analysis of finished food products. A 2.7-μm SPP (superficially porous particle) C18 column was used, allowing one to achieve very high throughput at a back-pressure considerably lower than that ...
Antioxidant therapy is very vital in todays world where we have to live with a lot of challenges and we go through a lot of stress. This certainly affects our body which can be clearly seen when one crosses his 40s. The aging is stimulated by oxidants which are produced in the body which is capable of binding to various sites in the body and can lead to the death of the cells. Antioxidants are chemically those compounds which react with Oxidants which are also known as Free radicals and make a complex with them and make them inactive. Since the aging process is very much affected by the free radicals, these antioxidants can be very useful for maintaining a fresh and healthy body.. The following are the main reasons which can lead to a formation of more free radicals:. ...
Acai berries are packed full of antioxidants. Antioxidants play an important role in our bodies, by mopping up excessive free radicals, which are the result of all the millions of chemical reactions that happen continuously in our cells to keep our bodies functioning. These free radicals are highly energetic, and bash around inside our cells, causing huge amounts of damage. In fact, free radicals are now known to contribute significantly to the aging process, as well as to illnesses like cancer and heart disease. The antioxidant found in high concentrations in acai berries is called anthocyanin. Anthocyanins are also found in red wine and other colourful fruits, and are known to be particularly effective at ensuring a healthy heart. You may have started seeing acai berry extract in your cosmetics- this is also due to its antioxidant power, and its ability to slow the aging of the skin. But the antioxidants are actually more effective if you eat them, since the body has the ability to send them ...

Oxidative systems are essential for the survival of cells. Side effects due of this dependence are the production of free radicals and other reactive oxygen species. They are increasing evidence of the involvement of such species in a variety of normal in vivo regulatory structures [33]. However, when an excess of free radicals is formed, they can overcome protective enzymes and cause destructive cellular effects by oxidizing membrane lipids, cellular proteins, DNA and enzymes, thus shutting down cellular respiration [11]. Several studies demonstrated that plant derived antioxidants may be useful in preventing the deleterious consequences of oxidative stress [34-36]. The importance of natural antioxidant stimulates the research interest on the investigation of protective effects of natural antioxidants from spices [37, 38]. This study demonstrated the free radical scavenging and antioxidant effects of A. lepidophyllus a Cameroonian non-timber forest product used as spice in local traditional ...

It is no secret that antioxidants are good for you. Just listen to any health professional speak for 30 minutes and youll probably hear "eat antioxidants!", but what are they and why are they important?. Antioxidants are primarily derived from plants and are responsible for many of the beautiful colors on your plate. They are made inside of plants and act as a natural shield from free radicals.. Free radicals are highly reactive chemicals that harm healthy cells. They can cause tissue damage (aging) and lead to cancer. They are essentially unbalanced cells that seek to balance themselves by oxidizing neighboring cells. Those neighboring cells then become unbalanced and chain reactions occur. We are exposed to free radicals every day in the form of the suns rays, pesticides in food, and exhaust from cars.. The benefits of antioxidants are that they neutralize these free radicals and prevent a hazardous and damaging chain reactions from occurring.. For the most part, humans do not naturally ...
This profile measures levels of the front line antioxidant molecules in cells and mitochondria, i.e. Co-enzyme Q10, red cell glutathione and two enzymes: superoxide dismutase (SODase) and glutathione peroxidase. Co-enzyme Q10 is the most important antioxidant inside mitochondria and also a vital molecule in oxidative phosphorylation (energy production in cells). A deficiency of Co Q10 can be corrected with supplementation. Superoxide dismutase (SODase) is the most important superoxide (free radical) scavenger in muscles. Deficiency can explain muscle pain and easy fatigue-ability in some patients. SODase is dependent on correct levels of copper, manganese and zinc and therefore checking levels gives clear indications for supplementation with appropriate doses of these minerals. Glutathione peroxidase requires glutathione and selenium for its synthesis. Again, as a functional test of these two important antioxidants, the glutathione peroxidase result gives indications for addressing deficiencies ...

quot;Alpha lipoic acid is a fatty acid found naturally inside every cell in the body. Its needed by the body to produce the energy for our bodys normal functions. Alpha lipoic acid converts glucose (blood sugar) into energy. Alpha lipoic acid is also an antioxidant, a substance that neutralizes potentially harmful chemicals called free radicals. What makes alpha lipoic acid unique is that it functions in water and fat, unlike the more common antioxidants vitamins C and E, and it appears to be able to recycle antioxidants such as vitamin C and glutathione after they have been used up. Glutathione is an important antioxidant that helps the body eliminate potentially harmful substances. Alpha lipoic acid increases the formation of glutathione." WEb MD ...
Hawai`i-grown coffee from Kauai (Yellow Catuai) and from Waialua (Kona Typica) contain bioactive compounds with properties that may modify type 2 diabetes risk. This pilot study aims to evaluate the antioxidant capacity and mineral and metal content of the coffees, and post-coffee consumption effects on plasma antioxidant capacity and fructosamine levels. In this randomized crossover study, 12 healthy adults consumed 24 oz of coffee per day for four weeks for each coffee intervention, which was separated by a one-week washout period. Data was collected at the end of the washout and intervention periods. Coffee brews were analyzed for mineral and metal content, as well as antioxidant capacity by oxygen radical absorbance (ORAC) assay. Plasma antioxidant capacity was measured at washout and after interventions using ORAC assay. Mineral analysis of coffee brews demonstrated no significant differences between the mineral components of each coffee. However, manganese content in a 24 oz cup of Waialua ...

Three native Turkish medicinal and aromatic plants (Artemisia absinthum, Artemisia santonicum and Saponaria officinalis) were investigated to analyze their antioxidant activity, total phenolic content and antimicrobial activity. Their total antioxidant activity was determined by using a β-carotene bleaching assay and their antimicrobial activity was determined by utilizing an agar disc diffusion assay. Methanol extracts of the three species analyzed showed high antioxidant activity and among them Artemisia absinthum possessed the highest quantity (71.78%). The total phenolic content (Folin-Ciocalteu assay) was shown to be between 6.57 µgGAE/mg dry weight basis (Saponaria officinalis) and 8.86 µgGAE/mg dry weight basis (Artemisia absinthum). There was a positive correlation (R = 0.819) between the total phenolic content and the antioxidant activity measured in the plant samples. The aqueous and methanol extracts of the aerial parts of the species showed antibacterial activities against a number of
Berries of Vaccinium spp. have long been an important source of food and pharmaceutical ingredients and are considered to have high antioxidant potential. Growing blueberries in Texas, United States is a substantial industry, but there is no report on their antioxidant capacity, total phenolics, and anthocyanins. This study evaluates antioxidant capacity and contents of total phenolics and anthocayanins in both fruits and leaves of 19 genotypes including five commercial cultivars and 11 selections of rabbiteye blueberry (V. ashei) and southern highbush (V. corymbosum hybrids), and three native species (V. darrowii, V. arboreum, and V. fuscatum) grown in Nacogdoches, Texas. Significant variations in antioxidant capacity (as measured by FRAP) and contents of total phenolics and anthocyanins in fruit were observed among different species, cultivars or selections with less variation observed among individual plants of the same genotype. Our data from rabbiteye blueberry selections and cultivars support the
The aim of study was investigation the impact of boiling and spontaneous fermentation on profile and content of betalains and antioxidant capacity of red beetroot. Betalains were analyzed by micro-HPLC-TOF-MS/MS method, while antioxidant capacity by three in vitro assays. Red beet products were abounded in betalains, with betanin, isobetanin, betanidin and vulgaxanthin I predominating among twenty two pigments identified. Boiling and fermentation of red beet reduced the content of betalains by 51-61% and 61-88%, respectively, however, this decline was limited when the peel was present. Microbial activity and softening of the matrix induced by the fermentation process led to the release of betalains responsible for strong antioxidant capacity of the juice formed. Generally, the treatment applied maintained and/or lowered antioxidant capacity of red beet materials obtained. Our findings indicate that red beet-derived products are valuable source of betalains, with their profile, content and ...
The antioxidant properties of protoporphyrin IX and related tetrapyrroles are poorly characterized. Therefore, eight tetrapyrroles, five of which are produced in vivo, were tested to assess their antioxidant capacities in the Salmonella reverse mutation, TEAC, FRAP and ORAC assays. Tertiary-butyl hydroperoxide (tert-BOOH) in the presence or absence of metabolic activation (ᓹ) was added to Salmonella strain TA102 together with the test compounds. In the absence of metabolic activation, the order of effectiveness was protoporphyrin , biliverdin , bilirubin ditaurate , bilirubin , biliverdin dimethyl ester , stercobilin , bilirubin dimethyl ester , urobilin. In the presence of S9, the effectiveness was reversed, with urobilin , biliverdin dimethyl ester , bilirubin dimethyl ester , stercobilin , biliverdin , bilirubin , bilirubin ditaurate , protoporphyrin. In the antioxidant capacity assays FRAP, TEAC and ORAC, mainly bilirubin, bilirubin ditaurate, biliverdin and protoporphyrin showed ...
The level of nerve growth factor (NGF) in the blood and seminal plasma of asthenozoospermia and oligoasthenozoospermia patients were compared to normozoospermic males and the relationship between NGF with sperm parameters and seminal antioxidant capacity were estimated to determine the role of NGF in the etiology of male infertility. Eighty-one infertile males and 40 normospermic control subjects were included in this stud. NGF levels were measured in the blood and seminal plasma, and its correlation with total antioxidant capacity (TAC), catalase (CAT) and glutathione (GSH) levels and sperm parameters were studied. There was a general trend of decreased in serum and seminal NGF concentrations of asthenozoospermic and oligoasthenozoospermic when compared to the normozoospermic samples. There was no significant association between NGF and seminal antioxidant status in asthenozoospermia and oligoasthenozoospermia males. Nevertheless, CAT positively correlated with sperm concentration, total sperm ...
Salvia (Salvia officinalis), a member of Lamiaceae family, is one of the most important herb known for its essential oil richness and extensive use in folk medicine. The aim of the present paper was to characterize the chemi cal composition of the essential oil of S. officinalis L. and to determine the antioxidant activity and total phenols from sage extract in an attempt to contribute to the use of Salvia officinalis as alternative product in medicine and natural antioxidant agent in foodstuff. Thirty two constituents were identified in S. officinalis oil that represented 99.98 % of the oil. The main components of the oil were α-thujone (28.27%), camphor (16.76%) and 1,8-cineole (10.01%). The total phenolic content and the antioxidant activity of plant extract were determined by Folin-Ciocalteu and by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging assays, respectively ...
