ESR study on the structure-antioxidant activity relationship of tea catechins and their epimers. (1/612)

The purpose of this study is to examine the relationship between the free radical scavenging activities and the chemical structures of tea catechins ((-)-epigallocatechin gallate (EGCG), (-)-epigallocatechin (EGC) and (-)-epicatechin (EC)) and their corresponding epimers ((-)-gallocatechin gallate (GCG), (-)-gallocatechin (GC) and (+)-catechin ((+)-C)). With electron spin resonance (ESR) we investigated their scavenging effects on superoxide anions (O-.2) generated in the irradiated riboflavin system, singlet oxygen(1O2) generated in the photoradiation-hemoporphyrin system, the free radicals generated from 2,2'-azobis(2-amidinopropane)hydrochloride (AAPH) and 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical. The results showed that the scavenging effects of galloylated catechins (EGCG and GCG) on the four free radicals were stronger than those of nongalloylated catechins (EGC, GC, EC, (+)-C), and the scavenging effects of EGC and GC were stronger than those of EC and (+)-C. Thus, it is suggested that the presence of the gallate group at the 3 position plays the most important role in their free radical-scavenging abilities and an additional insertion of the hydroxyl group at the 5' position in the B ring also contributes to their scavenging activities. Moreover, the corresponding phenoxyl radicals formed after the reaction with O-.2 were trapped by DMPO and the ESR spectra of DMPO/phenoxyl radical adducts were observed (aN=15.6 G and aHbeta=21.5 G). No significant differences were found between the scavenging effects of the catechins and their epimers when their concentrations were high. However, significant differences were observed at relatively low concentrations, and the lower their concentrations, the higher the differences. The scavenging abilities of GCG, GC and (+)-C were stronger than those of their corresponding epimers (EGCG, EGC and EC). The differences between their sterical structures played a more important role in their abilities to scavenge large free radicals, such as the free radicals generated from AAPH and the DPPH radical, than to scavenge small free radicals, such as O-.2 and 1O2, especially in the case with EGCG and GCG with more bulky steric hindrance.  (+info)

Formation of hydride-Meisenheimer complexes of picric acid (2,4, 6-trinitrophenol) and 2,4-dinitrophenol during mineralization of picric acid by Nocardioides sp. strain CB 22-2. (2/612)

There are only a few examples of microbial conversion of picric acid (2,4,6-trinitrophenol). None of the organisms that have been described previously is able to use this compound as a sole source of carbon, nitrogen, and energy at high rates. In this study we isolated and characterized a strain, strain CB 22-2, that was able to use picric acid as a sole source of carbon and energy at concentrations up to 40 mM and at rates of 1.6 mmol. h(-1). g (dry weight) of cells(-1) in continuous cultures and 920 micromol. h(-1). g (dry weight) of cells(-1) in flasks. In addition, this strain was able to use picric acid as a sole source of nitrogen at comparable rates in a nitrogen-free medium. Biochemical characterization and 16S ribosomal DNA analysis revealed that strain CB 22-2 is a Nocardioides sp. strain. High-pressure liquid chromatography and UV-visible light data, the low residual chemical oxygen demand, and the stoichiometric release of 2.9 +/- 0.1 mol of nitrite per mol of picric acid provided strong evidence that complete mineralization of picric acid occurred. During transformation, the metabolites detected in the culture supernatant were the [H-]-Meisenheimer complexes of picric acid and 2,4-dinitrophenol (H--DNP), as well as 2,4-dinitrophenol. Experiments performed with crude extracts revealed that H--DNP formation indeed is a physiologically relevant step in picric acid metabolism.  (+info)

Function of coenzyme F420 in aerobic catabolism of 2,4, 6-trinitrophenol and 2,4-dinitrophenol by Nocardioides simplex FJ2-1A. (3/612)

2,4,6-Trinitrophenol (picric acid) and 2,4-dinitrophenol were readily biodegraded by the strain Nocardioides simplex FJ2-1A. Aerobic bacterial degradation of these pi-electron-deficient aromatic compounds is initiated by hydrogenation at the aromatic ring. A two-component enzyme system was identified which catalyzes hydride transfer to picric acid and 2,4-dinitrophenol. Enzymatic activity was dependent on NADPH and coenzyme F420. The latter could be replaced by an authentic preparation of coenzyme F420 from Methanobacterium thermoautotrophicum. One of the protein components functions as a NADPH-dependent F420 reductase. A second component is a hydride transferase which transfers hydride from reduced coenzyme F420 to the aromatic system of the nitrophenols. The N-terminal sequence of the F420 reductase showed high homology with an F420-dependent NADP reductase found in archaea. In contrast, no N-terminal similarity to any known protein was found for the hydride-transferring enzyme.  (+info)

Fucoxanthin as the major antioxidant in Hijikia fusiformis, a common edible seaweed. (4/612)

The radical scavenging activity of Japanese edible seaweeds was screened by the DPPH (1-diphenyl-2-picrylhydrazyl) assay to evaluate the DPPH radical scavenging activity in organic extracts. The fresh brown alga Hijikia fusiformis showed the strongest DPPH radical scavenging activity, followed by Undaria pinnatifida and Sargassum fulvellum. The major active compound from Hijikia fusiformis in its acetone extract was identified as fucoxanthin by 13C-NMR spectroscopy.  (+info)

Dehydroepiandrosterone sulphate promotes hyaluronic acid-induced cervical ripening in rabbits. (5/612)

Hyaluronic acid (HA) stimulates the synthesis of interleukin (IL) 8, while dehydroepiandrosterone sulphate (DHEA-S) induces the expression of IL-8 and its receptor in the human cervical fibroblast. This has led us to investigate the effect of DHEA-S on HA-induced cervical ripening. Experiments were performed in pregnant rabbits using vaginal suppositories containing 1 mg HA, 30 mg DHEA-S, 30 mg DHEA-S + 0.1 mg HA, 30 mg DHEA-S + 1 mg HA, and 500 microl Witepsol-50 base (control). The effects were evaluated by measuring collagenase, gelatinase and elastase activities, water content, neutrophil infiltration, relative collagen concentration and histological assessment. The activities of collagenase, gelatinase and elastase were significantly increased in rabbits treated with DHEA-S + 1 mg HA compared with rabbits treated with DHEA-S + 0.1 mg HA (P < 0.009, P < 0.001, P < 0.009 respectively). Water content was markedly increased in rabbits treated with DHEA-S + 1 mg HA compared with DHEA-S + 0.1 mg HA treatment (P < 0.05). Neutrophil infiltration was markedly increased, while relative collagen concentration was significantly decreased with DHEA-S + 1 mg HA compared with the DHEA-S + 0.1 mg HA approach (P < 0.001, P < 0.002). The histology of cervices treated with DHEA-S + 1 mg HA showed the density of collagen to be markedly decreased, and collagen fibres irregularly separated. Increased vascularity with massive dilatation of blood vessels was also observed in these rabbits. We conclude that DHEA-S upregulates the HA-induced cervical ripening process.  (+info)

Glomerular filtration rate estimation from plasma creatinine after inhibition of tubular secretion: relevance of the creatinine assay. (6/612)

BACKGROUND: Estimation of glomerular filtration rate (GFR) from plasma creatinine concentration after inhibition of tubular creatinine secretion with cimetidine provides a good assessment in patients with various nephropathies and with non-insulin-dependent diabetes mellitus (NIDDM). The aim of this study was to compare cimetidine-aided GFR estimations using various creatinine assays. METHODS: In 30 outpatients with NIDDM GFR was measured as the urinary clearance of continuously infused [125I]iothalamate. Plasma creatinine concentration was analysed after oral cimetidine with an alkaline picrate (AP) method, with an enzymatic (PAP) assay and with HPLC. GFR estimations were calculated with the Cockcroft Gault formula (CG). RESULTS: AP creatinine concentrations were significantly higher than PAP or HPLC values. GFR estimations by AP (CG(AP) 66 +/- 19 ml/min/1.73 m2, mean SD) were significantly lower than GFR (89 +/- 30), whereas CG(PAP) (85 +/- 30) and CG(HPLC) (84 +/- 34 ml/min/1.73 m2) were not. Bland and Altman analysis showed a difference between CG(AP) and GFR of -22.4 +/- 17.7 ml/min/1.73 m2; this difference becomes larger when the GFR increases. The difference between CG and GFR was only -3.8 +/- 14.8 ml/min/1.73 m2 for PAP and -4.4 +/- 17.5 ml/min/1.73 m2 for HPLC, without any systematic difference. CONCLUSION: A good assessment of the GFR from plasma creatinine after cimetidine administration is possible when creatinine is measured with an enzymatic assay or with the less convenient HPLC method. The more widespread and cheaper alkaline picrate assay is not suitable for GFR-estimation.  (+info)

Cutting edge: CD40 ligand is a limiting factor in the humoral response to T cell-dependent antigens. (7/612)

CD40 ligand (CD40L) plays a crucial role in T cell-dependent B cell responses, but whether its abundance is a limiting factor in their development is unclear. This question was addressed in transgenic mice expressing the murine CD40L gene under the control of the IL-2-promoter (CD40Ltg+). The fraction of activated T cells from the CD40Ltg+ mice with detectable levels of surface CD40L was modestly greater (1.1- to 2-fold) than littermate controls and paralleled an approximately 1.8-fold increase in CD40L mRNA abundance. In response to trinitrophenol (TNP)-keyhole limpet hemocyanin and tetanus/diphtheria vaccine, CD40Ltg+ mice developed higher titers of high-affinity IgG and IgG1 Ab than wild-type mice. In contrast, the Ab response of CD40Ltg+ and control mice was similar in response to the T-independent Ag TNP-Ficoll. These results suggest that a modest increment in expression of CD40L accelerates the development of T-dependent responses, and that CD40L plays a limiting role in the induction of high-affinity Ab and Ab-class switching.  (+info)

Radical scavenging activity of phenylpropanoid glycosides in Caryopteris incana. (8/612)

In our screening program for antioxidants from traditional drugs and foodstuffs, one new phenylpropanoid glycoside, incanoside, was isolated together with four known phenylpropanoid glycosides, verbascoside, isoverbascoside, phlinoside A, and 6-O-caffeoyl-beta-D-glucose from the whole plant of Caryopteris incana (Thunb.) Miq. On the basis of chemical evidence and spectral analysis data, the structure of incanoside was determined to be 1-O-(3,4-dihydroxyphenyl)ethyl-O-beta-D-glucopyranosyl (1-->2)-alpha-L-rhamnopyranosyl(1-->3)-6-O-caffeoyl-beta-D- glucopyranoside. The four phenylpropanoid glycosides exhibited potent radical scavenging activity against DPPH, hydroxyl (.OH), and superoxide anion (O2-.) radicals.  (+info)

A detailed study of the kinetics of the heterogeneous catalytic ortho-para-hydrogen conversion on the solid free radical αα-diphenyl-β-picryl hydrazyl, shows that this conversion follows the usual first-order kinetics and that the rate is independent of pressure. Examination of the rate at 90, 190 and 290° K indicates that it decreases with increasing temperature. This type of behaviour has been observed for other paramagnetic heterogeneous conversions, and the negative activation energy has been assumed to indicate that the catalysis takes place in a physically adsorbed layer of hydrogen molecules. Some evidence that this is the true explanation of the phenomenon is shown by the results of studies of the adsorption of hydrogen on the free radical. Experiments carried out at 77 and 90° K indicate that hydrogen is physically adsorbed by the free radical to form a weakly sorbed layer which obeys the Langmuir adsorption isotherm for the case when the surface is only sparsely covered.

The Jaffe reaction is a colorimetric method used in clinical chemistry to determine creatinine levels in blood and urine. In 1886, Max Jaffe (1841-1911) wrote about its basic principles in the paper Über den Niederschlag, welchen Pikrinsäure in normalem Harn erzeugt und über eine neue Reaction des Kreatinins in which he described the properties of creatinine and picric acid in an alkaline solution. The color change that occurred was directly proportional to the concentration of creatinine, however he also noted that several other organic compounds induced similar reactions. In the early 20th century, Otto Folin adapted Jaffes research into a clinical procedure. The Jaffe reaction, despite its nonspecificity for creatinine, is still widely employed as the method of choice for creatinine testing due to its speed, adaptability in automated analysis, and cost-effectiveness, and is the oldest methodology continued to be used in the medical laboratory. It is this nonspecificity that has motivated ...

In this study, total phenolic, flavonoid contents, antioxidant capacity, and phenolic compositions of Castanopsis phuthoensis and Castanopsis grandicicatricata (Fagaceae family) were investigated. It was found that bark extracts were rich of phenolic contents, whereas leaf extracts were abundant of flavonoids. The total phenolics varied from 11.20 to 35.47 mg gallic acid equivalent g-1 dry weight (DW), and the total flavonoids were from 2.24 to 12.55 mg rutin equivalent g-1 DW. The results of antioxidant activity showed that the DPPH (1,1-diphenyl-2-picryl-hydrazyl) radical scavenging activity of the free phenolic extracts were higher than the bound phenolic extracts. Regarding the reducing power and β-carotene bleaching assays, the free phenolic extracts showed remarkably strong antioxidant capacity that were similar to the levels of the standard BHT (dibutyl hydroxytoluene) did. It could be concluded that free phenolic extracts were more effective in antioxidant activities than bound phenolic

Flavonoids are a class of natural polyphenolic compounds which cannot be synthesized by humans. These substances possess a series of biological properties, acting on biological systems as antioxidants. The purpose of this study was to analyze the properties of certain foods, determining the total flavonoids as well as their antioxidant activity and fat concentration. We evaluated several foods purchased at the local market, with respect to its antioxidant activity, using two experimental models, the discoloration of DPPH˙ radical and ABTS-. Some foods such as pitanga showed antioxidant activity. The lipid content of fatty foods like aaí, cacao and cupuaú was determined. Other foods, including pitanga, aaí, cacao and cupuaú, were evaluated for flavonoid content and antioxidant activity using multivariate statistical analysis (PCA) as a statistical tool to evaluate the correlation between these two parameters. As samples with ED50 up to 500 μg/mL show promising antioxidant activity, several

The antiradical property of a methanolic solution of 1, 1-diphenyl-2-picrylhydrazyl (DPPH) and the antioxidant activity of flavonoids in a β-carotenelinoleic acid were the two model systems studied. Different statistical tools used in this communication are stepwise regression analysis, multiple linear regressions with factor analysis as the preprocessing step for variable selection (FA-MLR) and partial least squares analysis (PLS). In both the activities the best equation is obtained from stepwise regression analysis, considering, both equation statistics and predictive ability (antiradical activity: R 2 = 0.927, Q2 = 0.871 and antioxidant activity: R 2 = 0.901, Q2 = 0.841). |inline-formula||alternatives| [...] |/alternatives||/inline
Background. C‐reactive protein (CRP) levels, an acute phase response index, predict cardiovascular outcome and are inversely related to visceral proteins, including albuminaemia in haemodialysis patients. Less definite is the relationship between inflammation and markers of somatic proteins such as serum creatinine in such patients. To explore these questions, a cross‐sectional analysis of potential predictors of serum creatinine was performed.. Methods.

Oxygen-derived free radicals play a critical role in atherogenesis and reperfusion injury. The present experiment evaluated the effects of carvedilol, a new beta adrenoreceptor blocker with potent free radical-scavenging activity, on myocardial ischemia and reperfusion injury in a hypercholesterolemic rabbit model. New Zealand rabbits were fed a normal diet, a high-cholesterol diet, or a high-cholesterol diet supplemented with 1200 ppm carvedilol or propranolol. Eight weeks later, the rabbits were subjected to 60 min of myocardial ischemia followed by 60 min of reperfusion. The nontreated cholesterol-fed animals experienced greater cardiac damage after ischemia and reperfusion than rabbits fed a normal diet (necrosis 51% +/- 4% vs. 28% +/- 3% in the normal-diet group, P , .01). In addition, nontreated cholesterol-fed rabbits showed a significantly decreased vasorelaxant response to ACh in U-46619-precontracted aortic rings (56% +/- 5% vs 90% +/- 3% in the control group, P , .001).

Free radicals are reactive oxygen species that are generated in our body by various endogenous systems. It is formed when our body is exposed to different physiochemical conditions. A balance between free radicals and antioxidants is necessary for normal physiological functions. Barnyard millet is one of the nutritious millet which can be useful in managing the level of diabetes mellitus, hyperlipidemia etc. The aim of this study is to analyze the presence of phytochemical, total phenolic content, antioxidant activity of aqueous and methanol extracts of barnyard millet at different forms such as raw millet, sprout millet and soaked millet. The phytochemical analysis was determined for alkaloids, phenols, flavonoids, tannin, terpenoids, saponins, proteins and carbohydrates. The methanol extract of soaked millet showed highest total phenolic content of 54.5±0.00mg of GAE/g and also it had highest DPPH radical scavenging activity of 87.90%. The DPPH scavenging activity was high in raw millet and low in

Oh, poor nutmeg! It has been way under looked for its ability to scavenge free radicals which are associated with cellular damage.. In a menthol extract, nutmeg had a lot of antioxidant power. Nutmeg demonstrated activity as a free radical scavenger, an antioxidant capacity for peroxyl and hydroxyl radical, and some phenolic activity. (Phenols have immune modulating properties.) One drawback in this study was that the extraction method could have altered the active constituents activity.. Black peppercorn, nutmeg, rosehip, cinnamon and oregano leaf were extracted with 50% acetone and 80% methanol, and evaluated for their radical-scavenging activities against cation (ABTS+), DPPH, peroxyl (ORAC) and hydroxyl (HO) radicals. For each extract, total phenolic content (TPC) and chelating activity were also determined. The extracts of all botanical samples showed significant radical-scavenging capacities, TPC and chelating abilities. The 50% acetone extract of cinnamon had the highest ABTS+-scavenging ...

Thank you so much for your thoughtful and insightful comments. I read the McAllister paper on a flight to the Bay Area. As I read about the potential adverse interaction of antioxidants with CBD, two patients came immediately to mind. Both of these patients have stage IV prostate cancer with significant bony metastases and PSA levels greater than 100. One of the patients, despite up to 300 mg of CBD daily (in addition to 100 mg of THC) has continued to show increasing levels of PSA. This patient takes over 25 supplements daily, most of which have significant antioxidant activity. As I read the article a light went off in my head…. an epiphany of sorts…. that his failure to respond might be related to his antioxidant use. I have already advised him to stop his antioxidants.. From this 2011 paper http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3410650/ by McAllister:. We determined that the ROS scavenger, α-tocopherol (TOC), could reverse the ability of CBD to inhibit the proliferation of ...

When changes occur, its easy to overlook less obvious areas that may be affected. We received two error reports that demonstrate this well. First, a hospital received a new batch of thromboplastin that changed the range of a therapeutic aPTT from 45-60 seconds to 40-70 seconds. A preprinted IV heparin nomogram was used for dose adjustments based on the aPTT values. For a short time, the preexisting nomogram was used with the new batch of thromboplastin, leading to unnecessary dose adjustments and repeat testing. In the second case, a hospital temporarily changed from morphine 15 mg/mL to a 50 mg/mL concentration to make infusions and PCA syringes. Compounding instructions in the pharmacy computer had been altered to reflect this change. But staff forgot that a specific standing order, which included a morphine drip and compounding instructions using the 15 mg/mL concentration, had been entered into the pharmacy computer ...

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 ...
