ACTL6A interacts with p53 in acute promyelocytic leukemia cell lines to affect differentiation via the Sox2/Notch1 signaling pathway.

Actin-like 6A (ACTL6A), a component of BAF chromatin remodeling complexes, is important for cell differentiation. Nevertheless, its role and mechanism in acute promyelocytic leukemia (APL) has not been reported. To identify the genes that may participate in the development of APL, we analyzed data from an APL cDNA microarray (GSE12662) in the NCBI database, and found that ACTL6A was up-regulated in APL patients.

Experimental study on removals of SO2 and NO(x) using adsorption of activated carbon/microwave desorption.

Unlabelled: Experimental studies on desulfurization and denitrification were carried out using activated carbon irradiated by microwave. The influences of the concentrations of nitric oxide (NO) and sulfur dioxide (SO2), the flue gas coexisting compositions, on adsorption properties of activated carbon and efficiencies of desulfurization and denitrification were investigated. The results show that adsorption capacity and removal efficiency of NO decrease with the increasing of SO2 concentrations in flue gas; adsorption capacity of NO increases slightly first and drops to 12.

Experimental study on removal of NO using adsorption of activated carbon/reduction decomposition of microwave heating.

Experimental studies were carried out on flue gas denitrification using activated carbon irradiated by microwave. The effects of microwave irradiation power (reaction temperature), the flow rate of flue gas, the concentration of NO and the flue gas coexisting compositions on the adsorption property of activated carbon and denitrification efficiency were investigated. The results show that: the higher of microwave power, the higher of denitrification efficiency; denitrification efficiency would be greater than 99% and adsorption capacity of NO is relatively stable after seven times regeneration if the microwave power is more than 420 W; adsorption capacity of NO in activated carbon bed is 33.

Advances on simultaneous desulfurization and denitrification using activated carbon irradiated by microwaves.

This paper describes the research background and chemistry of desulfurization and denitrification technology using microwave irradiation. Microwave-induced catalysis combined with activated carbon adsorption and reduction can reduce nitric oxide to nitrogen and sulfur dioxide to sulfur from flue gas effectively. This paper also highlights the main drawbacks of this technology and discusses future development trends.

Sonolytic degradation of dimethoate: kinetics, mechanisms and toxic intermediates controlling.

The sonolytic degradation of aqueous solutions of dimethoate, O,O-dimethyl S-[2-(methylamino)-2-oxoethyl]dithiophosphate, was examined. Optimal degradation rates were obtained at 619 kHz for continuous sonolysis and 406 kHz for pulse sonolysis. The primary pathways for degradation include hydroxyl radical oxidation, hydrolysis and pyrolysis on collapsing cavitation bubble interfaces.

[Pilot scale study on emergent treatment for As (III) pollution in water source].

Based on the conventional water treatment processes widely used in China, a pilot scale study was performed to investigate emergent treatment for arsenite pollution in water source. The results show that As removal efficiency can only reach to 71.85% by conventional water treatment process.

Sonolytic degradation of parathion and the formation of byproducts.

Ultrasonic degradation of parathion has been investigated in this study. At a neutral condition, 99.7% of 2.

Mechanism and kinetics of parathion degradation under ultrasonic irradiation.

The parathion degradation under ultrasonic irradiation in aqueous solution was investigated. The results indicate that at the conditions in question, degradation rate of parathion decreased with increasing initial concentration and decreasing power. The optimal frequency for parathion degradation was 600 kHz.

[Pilot study on pentavalent arsenic removal by coagulation and the strengthening effect of flocs recycling].

The pilot and bench scale studies on pentavalent arsenic removal by coagulation and the strengthening effect of flocs recycling were performed. The results show that above 95% As (V) in the raw water exists in the form of dissolved As (V). Furthermore, the removal efficiencies of dissolved arsenic and total arsenic by mixing, first flocculation, second flocculation, sedimentation, filtration units were 87.

[Emergent treatment process for raw water polluted by heavy metal Pb (II)].

Based on two common coagulants-polyferric sulfate (PFS) and polyaluminum chloride (PACl), some measurements and processes in the background of Pb (II) concentration sudden increase in water were studied. The removal efficiency of Pb(II) was compared between PAC and diatomite absorption with coagulation. The effect of coagulant dosage, initial concentration of Pb(II), pH value and KMnO4 preoxidation on coagulation were investigated.

[Emergent treatment of source water contaminated by representative herbicide molinate and ametryn].

Emergent treatment of source water polluted by representative herbicide molinate and ametryn was researched. The results indicate that activated carbon adsorption and prechlorination could achieve high efficiencies to remove the herbicides. The pseudo second-order adsorption kinetic model and Freundlich adsorption isotherm model can be used to describe the adsorption process and the adsorption equilibrium of molinate and ametryn adsorbed by powdered activated carbon (PAC) in raw water respectively.

Drinking water production by ultrafiltration of Songhuajiang River with PAC adsorption.

In recent years, membrane ultrafiltration (UF) of surface water for drinking water treatment has become a more attractive technology worldwide as a possible alternative treatment to conventional clarification. To evaluate the performance of ultrafiltration membranes for treatment of surface water in North China, a 48-m2 low pressure hollow fiber membrane ultrafiltration pilot plant was constructed. Ultrafiltration was operated in cross-flow and with powdered activated carbon (PAC) adsorption.
