Oxalate oxidase (E.C. 1.2.3.4) catalyses the conversion of oxalate and dioxygen to carbon dioxide and hydrogen peroxide (for reviews see [ 1-31). Oxalate oxidase activity has been detected in a number of organisms but the best biochemically characterised enzymes are from barley and wheat. The plant enzyme is isolated as a glycosylated homopentamer which is remarkably resistant to heat, SDS and ...

signaling amp-activated protein kinase (ampk), an energy sensing enzyme, has been implicated in controlling inflammation. in this study we investigated whether activation of ampk by metformin could protect the lung from lipopolysaccharide (lps)-induced acute injury by inhibitingng tlr4 pathway. male wistar rats were randomly divided into 3 groups (n=6): control group received normal saline (0.5...

Embryogenic tissue culture systems are utilized in propagation and genetic engineering of crop plants, but applications are limited by genotype-dependent culture response. To date, few genes necessary for embryogenic callus formation have been identified or characterized. The goal of this research was to enhance our understanding of gene expression during maize embryogenic tissue culture initia...

This paper introduces granting of “exclusive bidding rights” to a subset buyers as a way of fostering their pre-auction information acquisition. A revenue maximizing monopolist gives N∗, the socially efficient number of informed buyers, or N∗ + 1 buyers the exclusive right to bid, depending on a lumpsum value discovery (VD) cost. In the former case, equilibrium VD is efficient but allocation is...
