Synthesis and characterization of a novel rice bran protein-cerium complex for the removal of organophosphorus pesticide residues from wastewater.

The removal of organophosphorus pesticides residues from wastewater of fruits and vegetables processing as well as other agricultural processes by a low-cost, environment-friendly, and efficient strategy is necessary. In this study, rice bran protein (RBP) was cross-linked with ceric ammonium nitrate (CAN). The results showed that the cross-linking process generated new functional groups and significantly enhanced the chemical reactivity and adsorption capacity of RBP. The RBPC showed rough and porous surface structure compared with smooth surface structure for RBP. In addition, greatest adsorption capacity of 193.0 mg/g and omethoate removal efficiency of 72.1% was achieved, and the results fitted well with Langmuir isotherm and pseudo-second order models. Moreover, Omethoate (5 mg/L) removal efficiency maintained over 60% after 5 cycles of RBPC usage. Therefore, the obtained RBPC complex can be suggested as an efficient adsorbent for the removal of pesticide residues from wastewater.

Research Progress of Toll-like Receptors and Cerebral Ischemia / 沈阳医学院学报

Cerebrovascular disease is one of the main diseases that threaten human health and life,and the age of onset become younger and younger. Research shows that Toll-like receptors (TLRs) express in brain, have effects on neurons, play an important role in the occurrence and development of cerebral ischemia and secondary cerebral injury.It is clear that TLR2, TLR3, TLR4, TLR7 and TLR9 have influence on occurrence and development of cerebral ischemia. This is crucial for understanding the relationship between immune inflammation and nerve regeneration, and improving clinical treatment.
