    ABSTRACT: Polyphenol-rich fruit and vegetable intake has been associated with reduction in platelet hyperactivity, a significant contributor to thrombus formation. This study was undertaken to investigate the possible role of hippuric acid, a predominant metabolite of plant cyclic polyols, phenolic acids and polyphenols, in reduction of platelet activation-related thrombogenesis. Fasting blood samples were collected from 13 healthy subjects to analyse the effect of varying concentrations of hippuric acid (100 µM, 200 µM, 500 µM, 1 mM and 2 mM) on activation-dependant platelet surface-marker expression. Procaspase activating compound-1 (PAC-1) and P-selectin/CD62P monoclonal antibodies were used to evaluate platelet activation-related conformational changes and α-granule release respectively using flow cytometry. Platelets were stimulated ex vivo via the P2Y1/P2Y12 – adenosine diphosphate (ADP) pathway of platelet activation. Hippuric acid at a concentration of 1 mM and 2 mM significantly reduced P-selectin/CD62P expression (p=0.03 and p<0.001 respectively) induced by ADP. Hippuric acid at 2 mM concentration also inhibited PAC-1 activation-dependant antibody expression (p=0.03). High ex vivo concentrations of hippuric acid can therefore significantly reduce P-selectin and PAC-1 expression thus reducing platelet activation and clotting potential. However, although up to 11 mM of hippuric acid can be excreted in the urine per day following consumption of fruit, hippuric acid is actively excreted with a recorded Cmax for hippuric acid in human plasma at 250-300 μM. This is lower than the blood concentration of 1-2 mM shown to be bioactive in this research. The contribution of hippuric acid to the protective effects of fruit and vegetable intake against vascular disorders by the pathways measured is therefore low but could be synergistic with lowered doses of antiplatelet drugs and help reduce risk of thrombosis in current antiplatelet drug sensitive populations.

    ABSTRACT: Chicken egg yolk is a rich source of nutr ients providing high qua lity prote ins, vitamins, minerals , carotenoids and antioxidants. Chicken egg yolk, recovered from whole egg within 24 hours post- lay has been utilized as starting material in the preparation of a dietary supplement that has been demonstrated to lead to gains in muscle mass in a human clinical study. Further , an oil derived from chicken egg yolk has been utilized as a topical agent t o treat third degree burn injury. The molecular changes that take place in fertilized, chicken egg yolk during the first 24 hours post- lay are not well understood. By studying how the protein composition of egg yolk varies with fertility status , one can utilize this knowledge to develop egg yolk-based products that have been optimized f or specific applicat ions. In this study, a direct quantitative comparison was made between the proteome of fertilized chicken egg yolk with the proteome of unfertilized chicken egg yolk, both maintained at 20 degrees C and analyzed within 24 hours post-lay. Egg yolk proteins from each fertility state were digested with trypsin, labeled with distinct chemical labels (tandem mass tag reagents) and then combined in a 1:1 ratio. A TMT-labeled tryptic digest derived from chicken egg yolk proteins (fertilized and unfertilized) was separated using high-pH / low-pH reverse-phase chromatography and analyzed using mass spectrometry. 225 protein identifications were made from this TMT- labeled tryptic digest based on a minimum of 2 unique peptides observed per protein. 9 prote ins increased in abundance in fertilized egg yolk relative to unfertilized egg yolk and 9 proteins decreased in abundance in fertilized egg yolk relative to unfertilized egg yolk. Some proteins that increased in abundance in fertilized egg yolk play an important r ole in angiogenesis (pleiotrophin, histidine rich glycoprotein) and defense against pathogens (mannose-binding lectin, β-defensin 11, serum amyloid P-component , ovostatin). Based on this study, fertilized chicken egg yolk may be more useful as a starting material relative to unfertilized chicken egg yolk for the purpose of enriching or isolating proteins with pro-angiogenic and anti-microbial properties.

    ABSTRACT: Fourteen vitex honeys from China were investigated to evaluate its antioxidant and hepatoprotective activity against paracetamol-induced liver damage. All honey samples exhibited high total phenolic content (344–520 mg GAE per kg), total flavonoid content (19–31 mg Rutin per kg), and strong antioxidant activity in DPPH radical scavenging, ferric reducing antioxidant power and Ferrous ion-chelating ability. Nine phenolic acids were detected in vitex honey samples, in which caffeic acid was the main compound. Honey from Heibei Zanhuang (S2) ranked the highest antioxidant activity was orally administered to mice (5 g kg−1, 20 g kg−1) for 70 days. In high-dose (20 g kg−1), vitex honey pretreatment resulting in significant increase in serum oxygen radical absorbance capacity (15.07%) and decrease in Cu2+- mediate lipoprotein oxidation (80.07%), and suppression in alanine aminotransferase (75.79%) and aspartate aminotransferase (74.52%), enhancement in the superoxide dismutase and glutathione peroxidase activities and reduction in malondialdehyde (36.15%) and 8-hydroxy-2’-deoxyguanosine (19.6%) formation compared with paracetamol-intoxicated group. The results demonstrated the hepatoprotection of vitex honey against paracetamol-induced liver damage might attribute to its antioxidant and/or perhaps prooxidative property.

    ABSTRACT: Dietary supplements high in isolated isoflavones are commercially available for human consumption primarily to alleviate menopausal symptoms in women. The isoflavone composition, quantity and importantly their estrogenic potency are poorly standardised and can vary considerably between different products. The aim of this study was to analyse the isoflavone composition of 11 dietary supplements based on soy or red clover using the HPLC/MS/MS technique. Furthermore, we investigated the transactivational potential of the supplements on the estrogen receptors (ER), ER[small alpha] and ER[small beta], performing luciferase reporter gene assays. As expected, we found that the isoflavone composition varies between different products. The measured total isoflavone contents in various supplements were mostly comparable to those claimed by the manufacturers in their product information. However expressing the isoflavone content as isoflavone aglycone equivalents, soy-based supplements had a clearly lower quantity compared to the manufacturer information. All supplements transactivated more or less ER[small alpha] and ER[small beta] with a preference for ER[small beta]. The transactivational efficiency exceeded partly the maximal 17[small beta]-estradiol induced ER activation. While the different soy-based supplements revealed similar transactivation potential to both ERs, red clover-based supplements differed considerably. We conclude that different commercial dietary supplements based on soy or red clover vary in their isoflavone composition and quantity. They are estrogenically active, although especially the red clover-based supplements show considerable differences in their estrogenic potential to ER[small alpha] and ER[small beta]. Thus, different isoflavone-rich products cannot be necessarily compared regarding possible biological effects.

    ABSTRACT: Renal dysfunction is one of the major effects of DOCA (deoxycorticosterone acetate)-salt hypertension and there is an increasing amount of evidence that oxidative stress damages the function of the kidney. Grape seed proanthocyanidins (GSPE) have been reported to be potent anti-oxidants and free radical scavengers. The present study sought to investigate the ability of GSPE to prevent renal injury in DOCA-salt hypertensive rats and to explore the molecular mechanisms underlying its protective effects. A total of 54 Sprague Dawley (SD) rats were randomly divided into 7 groups: Sham group (n = 7), UnX-sham group (n = 8), DOCA-salt group (n = 8), GSPE150 group (150 mg kg(-1), n = 7), GSPE240 group (240 mg kg(-1), n = 8), GSPE384 group (384 mg kg(-1), n = 8) and ALM (amlodipine besylate tablets) group (5 mg kg(-1), n = 8), and treated for 4 weeks. Compared to sham group rats, renal injury was observed in DOCA-salt hypertensive group rats as the urine protein, KW/BW (kidney weight/body weight), degree of renal fibrosis, renal MDA (malondialdehyde) and Hyp (hydroxyproline) contents significantly increased (P < 0.01). Moreover, SOD (Superoxide Dismutase) activities decreased in the model group (P < 0.01). In contrast, DOCA-salt hypertensive rats treated with different dose of GSPE or ALM showed a significant improvement of renal injury with decreased urine protein, KW/BW, degree of renal fibrosis, renal total MDA and Hyp contents compared to the untreated group. In addition, SOD activities increased in the treatment group. Since the experimental modeling time was short, kidney damage occurs to a lesser extent. BUN (Blood Urea Nitrogen), Scr (Serum Creatinine) and UA (Uric Acid) contents did not appear significantly changed in all groups. Finally, the activation of JNK and p38 kinases in the kidney was suppressed in rats treated with GSPEs or ALM compared to the untreated group, suggesting that the inhibition of these kinase pathways by GSPE contributes to the improvement of renal function. Taking these results together, we conclude that the anti-hypertensive and anti-oxidative stress beneficial effects of GSPE on renal injury in rats with DOCA-salt hypertension occur via the attenuation of JNK and p38 activity.

    ABSTRACT: several studies have investigated the relationship between the estrogen receptor (ER) gene polymorphisms and the efficacy of estrogen replacement therapy in postmenopausal osteoporosis. However, the association of ER polymorphisms with the effects of dietary phytoestrogens on bone metabolism has not yet been reported. This study explores the possibility that ER alpha subtype (ERα) gene polymorphisms are involved in the effects of dietary phytoestrogens on bone mineral density (BMD) in postmenopausal women. a total of 301 postmenopausal southern Chinese women were enrolled. Dietary phytoestrogen intake was evaluated using a food frequency questionnaire. ERα polymorphisms were examined with restriction fragment length polymorphism at the polymorphic PvuII and XbaI sites within intron 1. Dual-energy X-ray absorptiometry scans were performed to determine the BMD of the lumbar spine and hip. the positive association of the lumbar spine BMD with dietary phytoestrogen intake was maintained only in groups with pp or xx genotypes (p < 0.05) and disappeared in groups with other genotypes. A positive association of the hip BMD with dietary phytoestrogen intake was observed only in the xx genotype group (p < 0.05). the association of the dietary phytoestrogen intake and BMD in southern Chinese postmenopausal women varied with ERα gene polymorphisms.

    ABSTRACT: Compounds in Fructus Gardeniae have been shown to possess a wide array of biological activities. However, Gardenia oil extracted from its fruit is still less reported, and its composition remains uncertain. To fully characterize lipophilic compounds in Gardenia oil, three conventional extraction (CE) and ultrasound-assisted extraction (UAE) methods were investigated. The oil extraction yield obtained by UAE was 51.8% higher than that of cold-pressed extraction (CPE) acquired. The fatty acid profile in UAE oil with different solvents was characterized by GC-MS. Petroleum ether was observed to be an ideal solvent with 8.59% extraction yield and 78.88% recovery rate, and with 3.11 ratios of unsaturated fatty acids to saturated fatty acids. Response surface methodology (RSM) with Box–Behnken Design (BBD) was applied to optimize conditions in UEA of oil to maximize extraction yield. Furthermore, the bioactive components in oil extracted by UAE were qualitatively identified and quantified by HPLC-DAD/ESI-MS2 and HPLC-DAD analysis. The eight compounds in Gardenia oil including geniposide, trans/cis-crocin-1, crocin-2, crocin-3, crocin-4, and trans/cis-crocetin were structurally revealed. The corresponding transfer rates of the bioactive components showed that the lipophilic trans/Cis-crocetin could be completely transferred from fruit to oil, with the highest concentration of 11.38 μg/g oil among all compounds quantified. These findings could deliver the potential application and large-scale production of functional Gardenia oil with bioactive components possessed health benefits.

    ABSTRACT: The phenolic profile and antioxidant activity of three endemic Laurus sp. from Portugal were analysed. Dried leaves of L. nobilis L., L. azorica (Seub.) Franco, and L. novocanariensis Rivas Mart., Lousã, Fern. Prieto, E. Días, J. C. Costa & C. Aguiar, collected in the mainland and in the Azores and Madeira archipelagos, respectively, were used to prepare different extracts (aqueous, ethanolic and hydroalcoholic). They were studied regarding their DPPH• scavenging activity, total phenolics and flavonoids contents, and main phenolic compounds were identified by HPLC-DAD-ESI-MS/MS. Total flavonoid contents were 30.1, 46.3, and 36.7 mg of epicatechin equivalents/g of sample (dry weight), for L. nobilis, L. azorica and L. novocanariensis, respectively. Epicatechin was the major compound, representing ~12.1 % of total flavan-3-ols in L. nobilis, ~25.6 % in L. azorica , and ~19.9 % in L. novocanariensis. Although all samples presented a similar phenolic profile, significant differences were observed in total contents and antioxidant activity.

    ABSTRACT: Naringin (Nar) is a major and active flavanone glycoside derivative of several citrus species. The antioxidant properties of Nar have an important function in its cardioprotective effects in various models. However, the effects of Nar on Nrf2 activation and the expression of its downstream genes in myocardial cells are yet to be elucidated. This study was designed to investigate the protective effects of Nar against anoxia/reoxygenation (A/R)-induced injury in H9c2 cells and determine its effects on the activity of Nrf2 and the expression of phase II antioxidant enzymes. H9c2 cells were pretreated with Nar for 6 h before exposure to A/R. A/R treatment severely injured the H9c2 cells, which was accompanied by apoptosis. Nar also suppressed the A/R-induced mitochondrial membrane depolarization and caspase-3 activation. Nar pretreatment significantly reduced the apoptotic rate by enhancing the endogenous anti-oxidative activity of superoxide dismutase, glutathione peroxidase, and catalase, thereby inhibiting intracellular reactive oxygen species generation. Moreover, the presence of Nar alone in H9c2 cells increased the nuclear translocation of Nrf2 in a dose- and time-dependent manner, as well as consistently increased the protein levels of heme oxygenase (HO-1) and glutamate cysteine ligase (GCLC). Nar increased the phosphorylation of ERK1/2, PKCδ, and AKT. However, the Nar-mediated Nrf2 activation and cardioprotection were abolished through the genetic silencing of Nrf2 by siRNA and partially inhibited by specific inhibitors of ERK1/2, PKCδ, and AKT. Therefore, Nar provided cardioprotection by inducing the phosphorylation of ERK1/2, PKCδ, and AKT, which subsequently activated Nrf2 and its downstream genes.

    ABSTRACT: The dysfunctional adipose tissue of rats fed a sucrose-rich diet was investigated following the time course of the development of oxidative stress, changes in proinflammatory cytokines and adiponectin levels, and their relationship with insulin resistance. We analyzed the morphometric characteristics of epididymal adipocytes, de novo lipogenesis enzyme activities and cellular antioxidant defense, inflammatory mediators, adiponectin levels and insulin resistance in rats fed a sucrose-rich diet for 3, 15 or 30 weeks and compared to those fed a control diet. The results showed a depletion of antioxidant enzyme activities in the fat pads of rats fed a sucrose-rich diet, with an increase in xanthine oxidase activity and lipid peroxidation after 3, 15 and 30 weeks on the diet. Superoxide dismutase activity and the redox state of glutathione showed a significant decrease at weeks 15 and 30. This was accompanied by visceral adiposity and enhanced lipogenic enzyme activities. An increase in the plasma levels of proinflammatory markers (TNF-α and IL-6) was recorded only after 30 weeks on the diet. A reduction in plasma adiponectin levels accompanied the time course of deterioration of whole-body insulin sensitivity. The results suggest that lipid peroxidation, depletion of antioxidant defenses and changes in inflammatory cytokines induced by a sucrose-rich diet contribute to the dysregulation of adipose tissue and insulin resistance. Finally, these results show that the progressive deterioration of adipose tissue function, which begins in the absence of both visceral adiposity and overweight, is highly dependent on the length of time on the diet.
