A two-stage water allocation strategy for developing regional economic-environment sustainability.

In this study, a new two-stage stochastic interval-parameter fuzzy programming strategy model is developed for regional economic-environment sustainability, considering the planning and management of water-resources and water-environment systems under uncertainty. The model is capable in addressing the complexity and uncertainties of the water system，which contains the concepts of economics and environment within an optimization framework. The objective of this research is to develop a participatory integrated assessment model, based on the water benefit and water environment security, with an application in the Sanjiang Plain area, China.

Role of electricity production in the anaerobic decolorization of dye mixture by exoelectrogenic bacterium Shewanella oneidensis MR-1.

This study investigated the anaerobic decolorization of the dye mixture containing methyl orange (MO) and naphthol green B (NGB) by Shewanella oneidensis MR-1. S. oneidensis MR-1 showed a strong ability to decolorize the dye mixture.

[Lactobacillus acidophilus NCFM affects host adhesion-related gene expression after adhering to host].

Objective: Adhering to the intestinal epithelial cells is one of the beneficial functions exerting by probiotics. We tested and verified the expression of adhesion-related genes in vivo and in vitro to understand the influence from Lactobacillus acidophilus NCFM on host cells.

Method: We selected the adhesion-related genes through GO (gene ontology) category from the Human Genome U133 Plus 2.

[Expression of PTX3 gene in Caco-2 cells treated with Lactobacillus acidophilus NCFM].

Objective: To study the expression of immunity and inflammatory mediator factor PTX3 in intestinal epithelial cells treated with Lactobacillus acidophilus NCFM and further to reveal the regulatory mechanism.

Methods: Caco-2 cells were cocultured with Lactobacillus acidophilus NCFM for 0, 2, 4, 8, 12 h and 0, 0.5, 1, 2, 4 h respectively, then the total RNA and protein were extracted.

[Expression profile analysis of intestinal Caco-2 cells treated with Lactobacillus acidophilus NCFM].

Objective: Lactobacillus acidophilus NCFM is a probiotic strain that promotes human health. We evaluated the influence of Lactobacillus acidophilus NCFM on the genetic expression patterns in the Caco-2 cells.

Methods: Caco-2 cells were treated with Lactobacillus acidophilus NCFM for 2h.

[Simulation of rice canopy evapotranspiration and water use efficiency under free-air CO2 enrichment].

By using FACE system, the microclimate in rice canopy and related physiological indices were observed continuously from the elongation to the maturing stage of rice growth, and the effects of FACE on the rice canopy evapotranspiration and water use efficiency were studied and simulated with energy balance analysis. The results showed that using P-M equation to describe the quantitative relationships of rice leaf stomatal conductance with photosynthetically active radiation (PAR) and vapour pressure deficit (VPD) could better simulate rice canopy evapotranspiraton under FACE and ambient conditions. During observation period, the total water use of rice in FACE plot had a 10 mm decrease, compared with that in control plot.
