Here we examined the protective effects of a commercial source of hydrogenized water on cultured human brain cells. Hydrogenized water was able to protect brain cells from oxidative stress and glutamate toxicity. At H2 concentrations above 0.01 mM the glutathione levels increased in cultured brain cells. The level of glutathione rose from approximately 500 to approximately 850 μM at the maximum dose of hydrogenized water with an EC50 of approximately 0.030 mM. Hydrogenized water was also able to enhance the signaling pathway for oxidative stress response mediated by Nrf2 (Nuclear factor erythroid 2 like factor). Treatment of cells with hydrogenized water at concentrations above 0.01 mM H2 induced activation of Nrf2 (EC50 approximately 0.05 mM). Hydrogenized water was also able to protect brain cells against glutamate toxicity. Using a DNA damage response element, (γH2AX, to monitor the damage of glutamate toxicity we found that concentrations of H2 above 0.01 mM protected cells from glutamate damage with an EC50 of approximately 0.05 mM H2. These in vitro results demonstrated that hydrogenized water can protect brain cells against common types of damage from oxidative stress and glutamate toxicity.","PeriodicalId":7859,"journal":{"name":"American Journal of Food and Nutrition","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82442891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nicolson","doi":"10.12691/AJFN-4-6-4","DOIUrl":"https://doi.org/10.12691/AJFN-4-6-4","url":null,"abstract":"Hydrogen has been shown in several clinical trials to be completely safe without adverse events and there are no warnings in the literature of its toxicity or adverse effects during long-term exposure. Molecular hydrogen has proven useful and convenient as a novel antioxidant and modifier of gene expression in many conditions where oxidative stress and changes in gene expression result in cellular damage. Our intracellular biomarker studies have shown that a hydrogenized water drink formula containing 2.6 ppm dissolved hydrogen was able to penetrate cellular membranes and function as an antioxidant in human liver cells (HePG2) utilizing the Cellular Antioxidant Assay (CAA). This assay uses the protection of a florescent probe as a marker for cellular damage by reactive oxygen species (ROS), such as peroxyl radical, and compares this to the known antioxidant standard, Quercetin. Using this system oxidative damage was reduced in a dose-dependent manner. One ml of hydrogenized water was found to possess antioxidant capacity equivalent to 0.05 µmole of quercetin. When examined in a human colon cell line (Caco-2 cells), hydrogenized water demonstrated a dose- and time-dependent permeability inhibition of an intracellular fluorescent glucose derivative (2-NBDG), indicating decreased glucose uptake. In another study, the impact of hydrogenized water on Akt phosphorylation (Ser473), a biomarker for insulin signaling, was monitored in human skeletal muscle cells. The hydrogenized water treatment markedly elevated the level of phosphorylation of Akt (Ser473) in a dose-dependent manner. The anti-aging effects of hydrogenized water were examined utilizing SIRT1 expression as a biomarker of aging in human umbilical cells (HUVECs). Hydrogenized water increased dose-dependent SIRT1 gene expression. Hydrogenized water also increased telomerase activity (an anti-aging biomarker in HUVEC cells) up to 148% when cells were treated with media containing 25% hydrogenized water formula. Increased telomerase activity caused by hydrogenized water may be able to protect telomeres from degradation, suggesting the possible use of hydrogenized water in therapeutic interventions of age-related diseases. These studies show that commercial hydrogenized water improved the levels or activities of a few intracellular biomarkers specific for antioxidant activity, glucose uptake, insulin signaling and SIRT 1 and telomerase activities. Industrial Relevance: The molecular hydrogen used in this study indicates that certain commercial sources of hydrogenized water can provide similar antioxidant and gene expression modifications seen in other sources of molecular hydrogen. The biomarkers evaluated here lend well to hydrogenized water’s biological activity relating to health conditions and aging.","PeriodicalId":7859,"journal":{"name":"American Journal of Food and Nutrition","volume":"14 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91489158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results: The nutritional role of mushroom products, as indirect probiotics, as direct prebiotics or as both (synbiotics), is justified by their influence on the inflammation process and on the gut microbioma through their contents of β-glucans, enzymes, and secondary metabolites. A possible new concept is advanced, that ultra-trace elements (e.g. germanium) may play an eventual prebiotic complementary role on the mode of action of mushrooms.

The antioxidant potential of the extract was assessed by its 2, 2-diphenyl-1-picrylhydrazyl (DPPH)-free radical scavenging activity, anti-hemolysis and anti-lipid peroxide assay. Membrane stabilizing effect of N. cadamba extract was assessed by using hypotonic solution- and heat-induced hemolysis of erythrocytes. Nutritional values such as total protein, lipid, carbohydrate, crude fiber, etc., along with minerals (Na, K, Mg and Fe) were analyzed by different established chemical methods. The water and ethanolic extracts of ripen fruit showed antioxidative and membrane stabilizing activity, and the extracts were found rich in polyphenols, flavonoids, β-carotene, lycopene and Vitamin-C. The fruits were also found rich in minerals. Thus, N. cadamba fruit could be used as a good source of food nutrients. Due to its antioxidative and membrane stabilizing property, this fruit could have a promising role to avert hemolysis-related anemia, as seen inevitable during famine-related malnutrition.","PeriodicalId":7859,"journal":{"name":"American Journal of Food and Nutrition","volume":"15 1","pages":"6-12"},"PeriodicalIF":0.0,"publicationDate":"2019-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85024612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effect of highly bioavailable polyphenols of lycosome-formulated dark chocolate (DC) containing co-crystallized astaxanthin (LF-DC-ASTX) on parameters of biological oxidation was investigated in this work. 94 healthy middle-aged volunteers (48 male, 46 female, 45 – 65 years old) were enrolled and randomized into four study groups. The 1st group were instructed to ingest conventional control DC (7.5 g). The 2nd group were asked to ingest capsules containing either 4 mg or 7 mg astaxanthin (ASTX), an algal antioxidant. The 3rd group were given DC bars (7.5 g) and 4 mg ASTX capsules for co-ingestion as two separate formulations. The 4th group were instructed to ingest LF-DC-ASTX containing different amounts of ASTX (1 mg, 2 mg, 4 mg or 7 mg) co-crystallized with 7.5 g of DC matrix. Each product was ingested once daily after breakfast for a period of 1 month. Serum levels of oxidized LDL (ox-LDL) and malonic dialdehyde (MDA) were measured after completion of 2 and 4 weeks of the study. No significant changes were observed in the values for ox-LDL or MDA concentrations in serum irrespective of cocoa content (70%, 72% or 85%) or duration of control DC intake. In contrast, ingestion of different doses of ASTX, as a single formulation, translated into reduction of oxidation markers without any dose-dependency. The inhibition of ox-LDL in volunteers following co-ingestion of DC and ASTX as two separate formulations was far greater than that seen for ASTX alone, revealing some additive effect of DC on lipid oxidation parameters. The inhibition of both oxidative markers was dose-dependent reflecting amount of ASTX in the DC matrix. These results may reflect greater bioavailability and improved pharmacokinetics for cocoa flavanols and ASTX following ingestion of LF-DC-ASTX. Therefore, nutraceutical formulations of DC fortified with ASTX can be successfully used for management of oxidative disorders associated with increased levels of ox-LDL.","PeriodicalId":7859,"journal":{"name":"American Journal of Food and Nutrition","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81875925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
