The skin is the part of body that most exposed to toxic substances; therefore, impact chemicals on should be thoroughly studied prior their implementation in any industrial-scale application. Herein, we examined and analyzed influence structure both cation anion 31 different ionic liquids (ILs) cytotoxicity against normal human dermal fibroblasts context present future potential applications. W...

BACKGROUND Regular exercise training is one of the core components of multifactorial fall-prevention programs. OBJECTIVE To compare the effect of Tai Chi and combined exercise prescription that consists of three main components of an exercise prescription on static balance, dynamic balance, fear of falling and mood. METHODS Sixty older adults aged 55-76 were randomly assigned to Group 1 (Ta...

Bovine aortic endothelial cells were cultured in medium containing [3H]glucosamine and concentrations of [“S]sulfate ranging from 0.01 to 0.31 mM. While the amount of [‘H]hexosamine incorporated into chondroitin sulfate and heparan sulfate was constant, decreasing concentrations of sulfate resulted in lower [‘“SIsulfate incorporation. Sulfate concentrations greater than 0.1 1 mM were required ...

The desulfurization of gas streams using aqueous iron(II)sulfate (Fe(II)SO4), zinc sulfate (ZnSO4) and copper sulfate (CuSO4) solutions as washing liquor is studied theoretically and experimentally. The desulfurization is accomplished by a precipitation reaction that occurs when sulfide ions and metal ions are brought into contact with each other. A thermodynamic study has been used to determin...

Epidemiologic and health impact studies have examined the chemical composition of ambient PM2.5 in China but have been constrained by the paucity of long-term ground measurements. Using the GEOS-Chem chemical transport model and satellite-derived PM2.5 data, sulfate and ammonium levels were estimated over China from 2004 to 2014. A comparison of the satellite-estimated dataset with model simula...
