PURPOSE To investigate the role of reactive oxygen species (ROS) as the prime initiators of the angiogenic response after alkali injury of the cornea and observe the effects of antioxidants in preventing angiogenesis. METHODS The corneal epithelia of SOD-1-deficient mice or wild-type (WT) mice were removed after application of 0.15 N NaOH to establish the animal model of alkali burn. ROS prod...
This study aimed to characterize and evaluate an inedible giant water lily as a bioenergy feedstock. The conversion of organics can produce renewable energy. Composition indicated that is excellent feedstock for bioethanol biogas production. Fermentation effluent wastes from anaerobic digestion were transformed directly into ethanol using alkali pretreatment. Under mild operating conditions, al...
The effects of non-steroidal anti-inflammatory drugs and prostaglandins E(2) and F(2alpha) on the secretory and electrical activity of isolated rabbit fundic mucosa have been studied. Spontaneous acid secretion was inhibited by serosal side application of sodium thiocyanate (6x10(-2)M) and the resulting alkali secretion measured by pH stat tiration. Serosal side application of indomethacin (10(...
In this study, steam explosion pretreatment was performed in cotton stalks, leading to 5-6 folds enhancements on biomass enzymatic saccharification distinctive in Gossypium barbadense and Gossypium hirsutum species. Sequential 1% H2SO4 pretreatment could further increase biomass digestibility of the steam-exploded stalks, and also cause the highest sugar-ethanol conversion rates probably by rel...
