Background: The presence of heavy metals in aquatic and terrestrial ecosystems causes harmful effects to living organisms in the environment. This research aimed to determine the potential of activated pumice stone (APS) as a sorbent for the removal of Cd, Cu, and Zn from wastewater. Methods: This research was conducted during 2013 on a laboratory scale. The study was performed using batch exp...

We investigated the effects of Astragalus polysaccharide (APS) on palmitate-induced insulin resistance in C2C12 skeletal muscle myotubes. Palmitate-reduced glucose uptake was restored by APS. APS prevented palmitate-induced C2C12 myotubes from impaired insulin signaling by inhibiting Ser307 phosphorylation of insulin receptor substrate-1 (IRS-1) and increasing Ser473 phosphorylation of Akt. Mor...

by MUSHTAQUE AHMAD, M.S. Washington State University December 2008 Chair: Richard J. Watts Oxidant interaction with subsurface materials is a major factor influencing the effective application of in situ chemical oxidation (ISCO) for contaminant destruction. The newest and least explored ISCO oxidant source is persulfate. Persulfate interaction with subsurface minerals was investigated as a bas...

Acute-phase serum (APS) collected from Plasmodium berghei-infected rats inhibited phagocytosis of trypsinized rat erythrocytes and of erythrocytes from P. berghei-infected rats. Macrophages (M phi) incubated with APS or heat-aggregated acute-phase serum (HAAPS) for 6 h, followed by 18 h incubation in serum-free medium, exhibited significantly higher levels of phagocytosis than M phi similarly c...

The toxic cyanides in gold cyanide residues produced the cyanidation process of extraction threaten environmental safety and inhibit recovery valuable metals. In this study, removal through persulfate-advanced oxidation was investigated, heat activation ultrasonic were tested for removal. results showed that residue could be removed by 2.0 wt.% potassium persulfate at pH 10.0 after 60 min react...

Background Antiphospholipid syndrome (APS) is an acquired thrombophilia that can be associated with decreased platelet counts. Case A 67-year-old woman presented with thrombocytopenia and a symptomatic right atrial mass suspicious of cardiac myxoma. Prolongation of the activated partial thromboplastin time (aPTT) was caused by a strong lupus anticoagulant, and bone marrow cytology was consisten...

BACKGROUND Activated hepatic stellate cells are the main source of excessive collagen deposition in liver fibrosis. Here we report the inhibitory effects of the combinational treatment of two natural products, astragalus polysaccharide (APS) and β-elemene (ELE) on the activation of human liver hepatic stellate cell line LX-2 cells. METHODS Cultured LX-2 cells were treated with different conce...

The aim of this study was to treat wastewater from washing, cutting or crushing intermediate bulk containers (IBCs), steel drums and plastic drums, using the sulfate radical-based oxidation method. In study, it planned make suitable for activated sludge treatment by applying neutralization after a process. Samples were taken industry three times these processes. To determine optimum conditions ...

The widespread occurrence of fluoroquinolone antibiotics, such as ofloxacin (OFX), in natural water and soil has received increasing attention terms their potentially dangerous impacts on public health ecosystems. In this study, the kinetics mechanisms OFX degradation by heat-activated persulfate (HAP) was investigated. Results showed that could be achieved effectively fitted well with pseudo-f...

Abstract In this study, low-cost siderite was used to activate peroxydisulfate (PDS, S2O82-)-inactivated Enterococcus faecalis study the inactivation characteristics and mechanism of siderite/PDS. The results showed that siderite/PDS had a better effect on at pH 3. sterilization increases with increase dosage, PDS concentration temperature. rate is decreased initial bacterial concentration.
