    Notes: The aim of this study was to evaluate several plant extracts with a view to developing melanogenesis inhibitors. In this study, 100 plant extracts were screened to elucidate their whitening effects using in vitro inhibition of tyrosinase and DOPA auto-oxidation activity. Several plant extracts such as Chaenomeles speciosa, Dryopteris crassirhizoma, Gastrodia ellata, Glycyrrhiza glabra, Morus alba, Myristica fragrans, Rheum palmatum and Sophora japonica showed inhibition of mushroom tyrosinase activity. Plant extracts including Bupleurum falcatum, Caragana sinica, Morus alba and Tussilago farfara showed inhibition of DOPA auto-oxidation activity. L'objet de cette etude etait d'evaluer plusieurs extraits vegetaux dans le but de developper des inhibiteurs de la melanogenese. Dans cette etude, on a crible 100 extraits vegetaux pour connaitre leurs effets blanchissants en utilisant in vitro l'inhibition de la tyrosinase et de l'activite auto-oxydante de la DOPA. Plusieurs extraits vegetaux tels que Chaenomeles speciosa, Dryopteris crassirhizoma, Gastrodia ellata, Glycyrrhiza glabra, Morus alba, Myristica fragrans, Rheum palmatum et Sophora japonica presentent une activite d'inhibition de la tyrosinase du champignon. Des extraits vegetaux comprenant Bupleurum falcatum, Caragana sinica, Morus alba et Tussilago farfara montrent une inhibition de l'activite d'auto-oxydation de la DOPA.

    Notes: Methanol aqueous extracts of 100 plants were screened for anti-oxidative activity using Fenton's reagent/ethyl linoleate system and for free radical scavenging activity using the 1,1-diphenyl-2-picryl hydrazyl free radical generating system. The results suggest that 14 plants - Alpinia officinarum, Areca catechu, Brassica alba, Cannabis sativa, Curcuma longa, Curcuma aromatica, Eugenia caryophyllata, Evodia officinalis, Paeonia suffruticosa, Rhaphanus sativus, Rheum palmatum, Rhus verniciflua, Trapa bispinosa, Zanthoxylum piperitum - may be potential sources of anti-oxidants. Eight plants - Citrus aurantium, Cornus officinalis, Gleditsia japonica, Lindera strychnifolia, Phragmites communis, Prunus mume, Schizandra chinensis, Terminalia chebula - may be the potential source of free radical scavengers from natural plant. Nous avons crible l'activite anti-oxydante de 100 extraits methanoliques aqueux de plantes en utilisant le systeme reactif de Fenton/linoleate, et leur activite de piege a radicaux libres en utilisant le systeme generateur de radicaux libres au 1,1-diphenyl-2-picryl-hydrazyle. Les resultats suggerent que 14 plantes - Alpinia officinarum, Areca catechu, Brassica alba, Cannabis sativa, Curcuma longa, Curcuma aromatica, Eugenia caryophyllata, Evodia officinalis, Paeonia suffruticosa, Rhaphanus sativus, Rheum palmatum, Rhus verniciflua, Trapa bispinosa, Zanthoxylum piperitum - peuvent etre des sources potentielles d'anti-oxydants. Huit plantes - Citrus aurantium, Cornus officinalis, Gleditsia japonica, Lindera strychnifolia, Phragmites communis, Prunus mume, Schizandra chinensis, Terminalia chebula - peuvent etre la source potentielle de pieges a radicaux libres a partir de plantes naturelles.

    Irradiation Effects on Free Radical Scavenging and Antioxidant Activity of Phytic Acid (2003)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: : Free radical scavenging and antioxidant activities of irradiated phytic acid at various concentrations were studied. Phytic acid sodium salt dissolved in deionized distilled water was irradiated at 0, 5, 10, 15, and 20 kGy. The degradation of phytic acid by irradiation was observed, and it was found that the concentrations had an effect on the degree of degradation. Stable 2,2-diphenyl-1-picrylhydrazyl radical scavenging ability of phytic acid was significantly increased by irradiation (P 〈 0.05) and was positively correlated with irradiation dose (P 〈 0.01). Antioxidant activity of phytic acid in lipid model systems was slightly increased by irradiation; however, at higher concentrations, the activity was reduced or was the same compared with nonirradiated phytic acid.

    Functional and Thermal Properties of Wheat, Barley, and Soy Flours and Their Blends Treated with a Microbial Transglutaminase (2005)

    Notes: The effects of transglutaminase (TG) on the functional and thermal properties of wheat, barley, and soy flours and their blends were investigated. Free amino and thiol groups and aromatic hydrophobicity in samples were decreased with TG treatment (P 〈 0.05), confirming the polymerization of proteins in flours by TG treatment. TG-treated samples had increased water-holding capacity, fat adsorption, and emulsion stability, and slightly decreased emulsion activity. The addition of barley or soy to wheat flours decreased fat adsorption and emulsion stability, but these values increased, upon TG treatment of the same blended samples, to levels as high as for untreated wheat alone. TG treatment did not significantly affect the transition peak temperature of the flour samples. However, TG treatment lowered the transition enthalpy of wheat blended with barley or soy flour, and, conversely, increased that of wheat flour samples alone. Results suggest that protein cross-linking by TG can produce unique and improved functionality even in wheat blended with barley or soy flour, and could provide opportunities for exploitation of this enzyme for product development.

    Effects of Alcohol Type and Amounts on Conjugated Linoleic Acid Formation During Catalytic Transfer Hydrogenation of Soybean Oil (2003)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: : Effects of alcohol type and amount on formation of conjugated linoleic acids (CLAs) in soybean oil were studied during catalytic transfer hydrogenation with a nickel catalyst and an alcohol as a hydrogen donor. Identification and quantification of CLA isomers in the oil were done by 100-m cyano-capillary column gas chromatography. Butanol and propanol showed the highest activity for the formation of CLAs, followed by ethanol and methanol. As the amount of ethanol in the reaction system increased from 0% to 2.5%, CLA formation increased. At the level of 2.5%, CLA formation decreased. CLA compositions in soybean oils were also affected by hydrogenation time and alcohol amount. Catalytic transfer hydrogenation with alcohol has an advantage over classic hydrogenation with a gaseous hydrogen in that soybean oil, with an extremely low level of t-C18:1 but high level of CLAs, could be produced.

    Notes: The Freeman–Sheldon syndrome is a congenital disease primarily affecting the facial, limb and respiratory muscles that give rise to classical clinical features including typical whistling face and short webbed neck associated with difficult intubation. We present successful awake nasotracheal intubation in a 6-year-old patient with typical clinical features of Freeman–Sheldon syndrome by using fiberoptic bronchoscope on two separate occasions.
