When lipids are exposed to heat, light and oxygen, it leads to oxidation. The addition of antioxidants is required to preserve colour, flavour and vitamin destruction. Present study was, therefore, planned to investigate pod coat of pigeon pea as possible sources of natural antioxidants and to assess their efficacy in stabilization of crude soybean oil during normal storage (28 days at 50°C). Study revealed that acetone pod coat extract of pigeon pea showed richness in total phenolics (17.72 mg/g), flavonoids (9.00 mg/g) and tannins (2.21 mg/g) while the extract of ethyl acetate was found enriched in tocopherols content (9.56 mg/g). The IC50 value of acetone extract was found to be lowest, exhibited potent antioxidant activity in the 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric thiocyanate (FTC) methods. After adding synthetic and natural antioxidants in oil, Peroxide, p-Anisidine, Thiobarbituric acid value, Conjugated dienes, trienes and free fatty acids content were measured every 4 days. Acetone pod coat extract (2000ppm) of pigeon pea gave strong antioxidant efficacy in stabilization of crude soybean oil and hence could be recommended as natural antioxidants for food applications.The research explored the possibility of using pod coat of pigeon pea as imminent sources of green antioxidants and to evaluate their efficacy in stabilization of crude soybean oil.

The aim of this experiment was to assess the antioxidative potential of the Biofield Energy Treated/Blessed Proprietary Test Formulation and Biofield Energy Treatment/Blessing per se to the animals on NG-nitro-L-arginine methyl ester hydrochloride (L-NAME) and high fat diet (HFD)-induced cardiovascular disorders in Sprague Dawley rats using various functional biomarkers. A test formulation was formulated including minerals (magnesium, zinc, copper, calcium, selenium, and iron), vitamins (ascorbic acid, pyridoxine HCl, vitamin B9, vitamin B12, and vitamin D3), cannabidiol (CBD) isolate, Panax ginseng extract, and β-carotene. The test formulation’s constituents were divided into two parts; one part was denoted as the untreated, while the other part and three group of animals received Biofield Energy Healing/Blessing Treatment remotely for about 3 minutes by a renowned spiritual leader, Mr. Mahendra Kumar Trivedi. The expression of superoxide dismutase (SOD) was elevated significantly by 198.46%, 208.73%, 191.73%, 211.75%, and 198.82% in the G5 (L-NAME + HFD + the Biofield Energy Treated test formulation), G6 (L-NAME + HFD + Biofield Energy Treatment per se to animals from day -15), G7 (L-NAME + HFD + the Biofield Energy Treated test formulation from day -15), G8 (L-NAME + HFD + Biofield Energy Treatment per se plus the Biofield Energy Treated test formulation from day -15), and G9 (L-NAME + HFD + Biofield Energy Treatment per se animals plus the untreated test formulation) groups, respectively than disease control group (G2). Moreover, the level of glutathione peroxidase (GPx) was significantly increased by 61.94%, 118.49%, 82.96%, 141.89%, and 262.02% in the G5, G6, G7, G8, and G9 groups, respectively as compared to the G2 group. Lipid peroxidase (LPO) was decreased by 14.21%, 30.98%, 38.66%, and 32.67% in the G6, G7, G8, and G9 groups, respectively than G2 group. Additionally, the level of myeloperoxidase (MPO) was decreased by 28.46%, 10.87%, 12.41%, and 13.35% in the G6, G7, G8, and G9 groups, respectively than G2. Further, the level of oxidized low density lipoprotein (LDL) was reduced by 65.38%, 65.11%, 71.53%, 79.26%, and 66.57% in the G5, G6, G7, G8, and G9 groups, respectively than G2. Besides, in heart tissues, the level of catalase (CAT) was significantly increased by 68.20%, 63.69%, 126.03%, 124.54%, and 112.23% in G5, G6, G7, G8, and G9 groups, respectively than G2 group. Moreover, in kidney tissues, the level of CAT was significantly increased by 22.48%, 23.43%, and 10.95% in the G6, G7, and G9 groups, respectively than G2. Overall, the data suggested a significant antioxidant activity by increasing the levels of SOD, CAT, GPx, and reducing the levels of LPO, MPO, and oxidized-LDL in various tissue fluids and that might be beneficial for cardiovascular disorders.

The aim of the study was to evaluate the antioxidant potential of Biofield Energy Healing (the Trivedi Effect®) based test formulation using TNBS-induced colitis animal model. Each ingredient of the test formulation was divided into two parts. One part was denoted as the control without any Biofield Energy Treatment, while the other part was treated with Biofield Energy Treatment by Mr. Mahendra Kumar Trivedi and defined as the Biofield Energy Treated test formulation. The colon tissue was used for the estimation of anti-oxidation activity for catalase (CAT), glutathione (GSH), lipid peroxidation (LPO) product, myeloperoxidase (MPO), superoxide dismutase (SOD), and glutathione peroxidase (GPx) using standard procedure. The antioxidant results showed that the CAT level was significantly increased by 95.4% (p≤0.001), 72.3%, 47.6%, and 13.9% in the Biofield Energy Treated test formulation (G5), Biofield treatment per se to animals (-15 days)(G6), Biofield Energy Treatment per se to animals plus Biofield Energy Treated test formulation (-15 day) (G8), and Biofield Energy Treatment per se to animals plus untreated test formulation (G9) groups, respectively as compared to the untreated test formulation group (G4). Further, colon GSH activity was found to be significantly increased by 23.2% (p≤0.05) 15.4%, and 15.5%, in G5, G6, and G9 groups, respectively with respect to G2 group. In addition, colon LPO activity data suggested that it was decreased by 12%, 17%, 18%, and 19.1% in G5, G6, Biofield Energy Treated test formulation (-15 day) (G7), and G8 groups, respectively, as compared with the G2 group. The level of MPO showed a significant (p≤0.001) reduced level by 27.9%, 22%, 14.5%, 16.6%, and 25.3% in G5, G6, G7, G8, and G9 groups, respectively as compared with the G2 group. The level of colon SOD was increased by 16.7% and 14.2% in the G5 and G9 groups, respectively as compared with the untreated test formulation, G4 group. Colon GPx level was increased by 177.6%, 71.4%, 71.4%, 161.2%, and 114.3% in G5, G6, G7, G8, and G9 groups, respectively as compared with the G2 group.

Plant-based preparations are commonly used in Suriname (South America) as adaptogens. In this study, fifteen alleged adaptogenic Surinamese plants have been assessed for their antioxidant activity (AA), total phenolic contents (TPC), and total flavonoid contents (TFC). The investigated plants were Anacardium occidentale, Spondiasdulcis, Annona muricata, Euterpe oleracea, Oenocarpus bacaba, Luffa acutangula, Punicagranatum, Malpighia emarginata, Syzygiumaqueum, Syzygiumcumini, Averrhoa carambola, and Renealmiaalpinia (fruit); Hibiscus sabdariffa (calyx); as well as Aloe vera and Cestrum latifolium (leaf). Aqueous extracts (1 - 3,000 μg/ mL) were prepared. AA was determined by the FRAP and the DPPH assay. TPC and TFC were determined by the Folin-Ciocalteu’s and an AlCl3 colorimetric method, respectively, using gallic acid (GA) and rutin (R), respectively, as standards. Data are means ± SDs (n ≥ 3; P < 0.05). FRAP values and DPPH-scavenging activities correlated positively with each other and with TPC but not with TFC. The preparations from M. emarginata, A. carambola, A. occidentale, O. bacaba, C. latifolium, and H. sabdariffa displayed the highest FRAP values (54 ± 14 to 412 ± 30 µM Fe2+/100 μg), DPPH-scavenging activities (IC50 values of 33 ± 14 to 250 ± 50 μg/mL), and TPC (51 ± 4 to 280 ± 78 µM GAE/100 µg). TFC of all samples were ≤ 10 ± 3 RE/100 µg. The adaptogenic properties of these plants may (partially) be attributed to their high content of antioxidant phenolic compounds and may make them candidates of novel sources of health-promoting antioxidants.

Objective Search of pathogenetic mechanisms and risk factors of atherosclerosis in the employees of the cleaning service in Tbilisi. Materials and Methods As a result of a preliminary survey and examination of 200 employes of Tbilisi cleaning service aged 25-45 years (2014-2016), 22 patients with angina, hypercholesterolemia, intimae-media thickness > 0.65 mm, were selected into I group, and 23 individuals without these disorders into II group. In the blood plasma of the selected patients the intensity of oxidative metabolism parameters, TAA and MDA were determined. The variance and correlation analysis (АNOVA) was used for conducting the comparative analysis of the levels of studied parameters. Results In the combined group (I+II) there are several reliable correlations between the Age -TCol, Age-MDA, BMI-Tg, BMI-MDA, LDLChol-HDLChol, LDLChol–TChol, HDLChol-TChol, LDLChol-MDA, LDLChol-TAA. no correlation between these parameters in individual groups (I and II) was found. That indicates that we have an imaginary correlation related to the large intergroup difference between the average values of the group indicators, that is the values of various indicators change during the development of the pathological process, but there is no causal relationship between these alterations. The reliable TAA-MDA correlation in the combined group (I+II) is related to the high anticorrelation between these parameters and the significantly higher average value of TAA in the low-risk group (II) in comparison to the high-risk group (I). Conclusion The results analysis indicates both the diagnostic value of redox status indicators and their leading role in the atherogenesis processes. In populations with a high risk of atherosclerosis, monitoring of serum TAA is recommended.

The paper explores the formation of a-oxoaldehydes during the interaction of glucose metabolites with hydroxyl or alkoxyl radicals. Hydroxyl radicals were generated under radiolysis of aqueous solutions, and alkoxyl radicals (t-BuO) were obtained in the model system tert-butyl hydroperoxide/Fe2+. High-performance liquid chromatography revealed that methylglyoxal was one of the organic products resulting from t-BuO-induced transformations of fructose-1,6-bisphosphate under hypoxic conditions. The interaction of lysine and methylglyoxal one of the main targets of a-oxoaldehydes in proteins was also studied. As chemiluminescence and EPR spectroscopy demonstrated, this reaction generates a methylglyoxal anion radical, a cation-radical of methylglyoxal dialkylamine and a superoxide anion radical. EPR signal of methylglyoxal-derived free radicals was observed in hypoxia, whereas only the trace amounts of these free radicals were recorded in the aerated reaction medium.

Numerous studies have reported the health benefits of consuming fruits and vegetables that contain antioxidant properties. Within the group of fruits considered exotic, some are accessible and only consumed in their place of origin, such as soursop, noni, kiwi, pitahaya, and others. Anacardiumoccidentale, cashew, is a crop native to the Brazilian northeast that has excellent medicinal and nutritional properties. Because few studies have characterized cashew produced in Mexico, in the present work, the physicochemical properties and antioxidant capacity of cashew apple (red and yellow varieties) and its nut were studied. The content of total phenolic compounds and the antioxidant capacity were higher in the nut (174.19±20.98 GAE mg/100 g db) while cashew red pulp showed a superior value of the phenol content (159.75±12.91 GAE mg/100 g db) to that of yellow cashew pulp (151.9±5.23 GAE mg/100 g db). A high value was obtained for the TPC of the husk of cashew nut (74.30 mg GAE/g) compared with those of the kernel and false fruit. Red cashew presented a higher antioxidant capacity at 77.65 μmol Trolox/g and was superior to that of the kernel (38.52±2.9 μmol Trolox/g). Because cashew apple is usually discarded, a marmalade based on the pulp is proposed as an alternative for its conservation because it has a high content of phenolic compounds that is conserved for six weeks of shelf life.

Xanthine oxidase is a commercially important enzyme with wide area of medical applications to develop diagnostic kits. Xanthine oxidase was extracted, purified and characterized from sheep liver (SLXO). The purification procedure involved acetone precipitation and chromatography on DEAE-cellulose and Sephacryl S-300 columns. The sheep liver xanthine oxidase was homogeneously purified 31.8 folds with 3.5 U/mg specific activity and 24.1% recovery. SLXO native molecular weight was 150 kDa and on SDS-PAGE appeared as single major band of 75 kDa representing a homodimer protein. Isoelectric focusing of the purified SLXO resolved into two closely related isoforms with pI values of 5.6 and 5.8. The apparent Km for xanthine oxidase at optimum pH 7.6 was found to be 0.9 mM xanthine. FeCl2 and NiCl2 increased the activity of SLXO, while CuCl2 and ZnCl2 were found to be potent inhibitors of the purified enzyme. Allopurinol inhibits SLXO competitively with one binding site on the purified molecule and Ki value of 0.06 mM.
