A dual luciferase reporter (DLR) system utilizing firefly and Renilla luciferases was developed and tested in a model rhizobacterium, Pseudomonas putida KT2440. The DLR was applied to simultaneously analyze expression of three putative bacterioferritin genes (bfralpha, bfrbeta, and bfr) and assess the cellular iron status of strain KT2440 by monitoring expression of the Fur-regulated fepA-fes p...

The accumulations of Cd, Ni, Pb, and Cr were measured in muscle, gill, kidney, and liver of Platycephalus indicus and Pampus argenteus. Our results indicated that all metals were found to be the highest in tissues in P. indicus (benthic species). Except Ni in P. indicus, concentrations of metals and bioaccumulation factor were in the following sequence: liver > kidney > gill > muscle. The data ...

In this paper, a new FEPA portfolio forecasting model is based on the EMD decomposition method. The special empirical modal of financial time series, principal component analysis, and artificial neural network to forecast for nonlinear, nonstationary, multiscale complex series predict stock market indices foreign exchange rates empirically investigate hot area in research. combined proposed pap...
