Wastewaters from the olive oil industry are a regional environmental problem. Their phenolic content provides inherent toxicity, which reduces treatment potential of conventional biological systems. In this study, Sulfate Radical based Advanced Oxidation Processes (SRbAOPs) compared with advanced oxidation processes (namely Fenton’s peroxidation) as depuration alternative. Synthetic mill wastew...

Leachate pollution is one of the main problems in landfilling. Among the most problematic parameters in stabilized leachate are COD, ammonia, and color. The treatment technology that can be used may differ based on the type of leachate produced. Even after treatment, the effluent characteristics are always hard to comply with the discharge standard. Ozonation is one of the chemical processes th...

in this study, degradation of p-chlorophenol (p-cp) was evaluated using persulfate (ps) activated zerovalent iron (zvi) based ultraviolet (uv) in a bench scale photoreactor. the effect of operational parameters such as solution ph (3, 7, and 11), reaction time (0-60 minutes), zvi dosage (0.15, 1.25, 0.5, 1, and 1.5 mm), ps concentration (0.5, 1.5, 2, 2.5, 3, and 4 mm), and initial p-cp concentr...

Sulfate radical (SO4(•-)) is a strong, short-lived oxidant that is produced when persulfate (S2O8(2-)) reacts with transition metal oxides during in situ chemical oxidation (ISCO) of contaminated groundwater. Although engineers are aware of the ability of transition metal oxides to activate persulfate, the operation of ISCO remediation systems is hampered by an inadequate understanding of the f...

To investigate voltage-gated potassium channels underlying action potentials (APs), we simultaneously recorded neuronal APs and single K(+) channel activities, using dual patch-clamp recordings (1 whole cell and 1 cell-attached patch) in single-layer V neocortical pyramidal neurons of rat brain slices. A fast voltage-gated K(+) channel with a conductance of 37 pS (K(f)) opened briefly during AP...

The use of heat-activated peroxymonosulfate oxidation for the degradation antibiotic compound sulfamethoxazole (SMX) was studied in this paper. It found that process follows a pseudo-first order kinetic model. Increasing oxidant concentration and/or activation temperature led to higher efficiency. pH from 3 9.5 resulted efficiency as well, although SMX significantly inhibited at 11. Through rad...

Antiphospholipid syndrome is a multisystem autoimmune disease , characterized by arterial and venous thrombosis, recurrent fetal loss, and persistent circulating antiphospholipid antibodies [1]. This syndrome with protean clinical manifestations can be either primary or secondary to other autoimmune disease, mainly systemic lupus erythematosus. Whereas APS in adults has been well characterized,...

In this study, the degradation of sulfonamide antibiotics was investigated through persulfate-enhanced UV advanced oxidation process. Factors that may affect efficiency were analyzed. Results showed persulfate imposed a significant enhancement on process during sulfathiazole degradation. The combined UV/persulfate can effectively remove about 96% within 60 min. With increase in dosage persulfat...

We investigated the synergism between shRNAs against Bcl-xL and doxorubicin (DOX) using aptamer-conjugated polyplexes (APs) in combination cancer therapy. Synergistic and selective cancer cell death was achieved by AP-mediated co-delivery of very small amounts of DOX and Bcl-xL-specific shRNA, which simultaneously activated an intrinsic apoptotic pathway. A branched polyethyleneimine (PEI) was ...
