Bimetallic Cu@Ru Core-Shell Structures with Ligand Effects for Endo-Exogenous Stimulation-Mediated Dynamic Oncotherapy.

Dynamic therapies, which induce reactive oxygen species (ROS) production through endogenous and exogenous stimulation, are emerging as attractive options for tumor treatment. However, the complexity of the tumor substantially limits the efficacy of individual stimulus-triggered dynamic therapy. Herein, bimetallic copper and ruthenium (Cu@Ru) core-shell nanoparticles are applied for endo-exogenous stimulation-triggered dynamic therapy.

Sustainable treatment of nitrate-containing wastewater by an autotrophic hydrogen-oxidizing bacterium.

Bacteria are key denitrifiers in the reduction of nitrate (NO -N), which is a contaminant in wastewater treatment plants (WWTPs). They can also produce carbon dioxide (CO) and nitrous oxide (NO). In this study, the autotrophic hydrogen-oxidizing bacterium sp TH20 was isolated for sustainable treatment of NO -N in wastewater.

Ecological and toxicological assessments of anthropogenic contaminants based on environmental metabolomics.

There has long been a great concern with growing anthropogenic contaminants and their ecological and toxicological effects on living organisms and the surrounding environment for decades. Metabolomics, a functional readout of cellular activity, can capture organismal responses to various contaminant-related stressors, acquiring direct signatures to illustrate the environmental behaviours of anthropogenic contaminants better. This review entails the application of metabolomics to profile metabolic responses of environmental organisms, e.

Highly efficient ammonium removal through nitrogen assimilation by a hydrogen-oxidizing bacterium, Ideonella sp. TH17.

Ideonella sp. TH17, an autotrophic hydrogen-oxidizing bacterium (HOB), was successfully enriched and isolated from activated sludge in a domestic wastewater treatment plant (WWTP). Batch experiments were conducted to identify the cell growth and ammonium (NH-N) removal, and to verify the pathways of nitrogen utilization under different conditions.

Mercury methylation by Geobacter metallireducens GS-15 in the presence of Skeletonema costatum.

In this study, bacterial mercury (Hg) methylation was investigated under the influence of red-tide algae of Skeletonema costatum (S. costatum). The distribution and speciation of total mercury (THg) and methylmercury (MeHg) were profiled by employing Geobacter metallireducens (G.

Inhibitory effects of Skeletonema costatum on mercury methylation by Geobacter sulfurreducens PCA.

Algae and mercury (Hg) are ubiquitous in marine environments. In this study, we investigated the effects of a typical marine algae of diatom Skeletonema costatum on Hg methylation by an iron-reducing bacterium of Geobacter sulfurreducens (G. sulfurreducens) PCA.

A novel rice C2H2-type zinc finger protein lacking DLN-box/EAR-motif plays a role in salt tolerance.

A cDNA for the gene ZFP182, encoding a C2H2-type zinc finger protein, was cloned from rice by RT-PCR. ZFP182 codes an 18.2 kDa protein with two C2H2-type zinc finger motifs, one nuclear localization signal and one Leu-rich domain.
