Bovine aortic smooth-muscle cells, bovine aortic endothelial cells, and IMR-90 human embryonic lung fibroblasts were tested to determine their ability to use cysteine or cysteine metabolites as a source of sulphate (SO4). Cells were incubated in SO4-depleted medium containing [3H]glucosamine plus 0.2 mM-cystine, 0.3 mM-cysteinesulphinic acid or 0.3 mM-sulphite (SO3). The [3H]chondroitin sulphat...

We treated 2,4,6-trinitrotoluene (TNT) red water from the Chinese explosive industry with activated coke (AC) from lignite. Since the composition of TNT red water was very complicated, chemical oxygen demand (COD) was used as the index for evaluating treatment efficiency. This study focused on sorption kinetics and equilibrium sorption isotherms of AC for the removal of COD from TNT red water, ...

Linear alkylbenzenesulphonate (LAS) (Fig. 1) is, apart from soap, the dominant surfactant in detergents worldwide (about 2·5× 10 t year, Schulze 1996). Commercial LAS is a mixture of linear alkanes (C10 to C13) each subterminally substituted with a single (4-sulfophenyl) moiety, and this mixture is the synthetic chemical product whose biodegradation has been examined to the greatest extent by r...

In order to reduce the environmental smog caused by coal combustion, air pollution control devices have been widely used in coal-fired power plants, especially of wet flue gas desulfurization (WFGD) and electrostatic precipitator (WESP). this work, particulate matter with aerodynamic diameter less than 10 μm (PM10) sulfur oxides (SOx) studied a plant. The plant is equipped selective catalytic r...

Ag[B(S2O7)2] represents the very first precious metal borosulfate containing disulfate groups, i. e. S?O?S bridges, and thus further enriches crystal chemistry of transition borosulfates. By thermal release SO3 originating from complex anions [B(S2O7)2]? condense to one-dimensional chains in Ag[B(SO4)2] solely B?O?S bridges.

The DNA of patients taking immunosuppressive and anti-inflammatory thiopurines contains 6-thioguanine (6-TG) and their skin is hypersensitive to ultraviolet A (UVA) radiation. DNA 6-TG absorbs UVA and generates reactive oxygen species that damage DNA and proteins. Here, we show that the DNA damage includes covalent DNA-protein crosslinks. An oligonucleotide containing a single 6-TG is photochem...

Controlling charge transport through individual molecules and further understanding the effect of anchoring groups on charge transport are central themes in moleculebased devices. However, in most anchoring effect studies, only two, or at most three nonthiol anchoring groups were studied and compared for a specific system, i.e., using the same core structure. The scarcity of direct comparison d...
