Ammonium nitrogen removal from wastewater has been of considerable concern for several decades. In the present research, we examined chemical precipitation recycle technology (CPRT) for ammonium nitrogen removal from coking wastewater. The pyrolysate resulting from magnesium ammonium phosphate (MAP) pyrogenation in sodium hydroxide (NaOH) solution was(More)
A new type of absorber, a four-tined fish-spear-like resonator (FFR), constructed by the two-photon polymerization process, is reported. An absorbance of more than 90% is experimentally realized and the resonance occurs in the space between the tines. Since a continuous layer of metallic thin film covers the structure, it is perfectly thermo- and(More)
The morphologies of poly(lactic acid)-b-Pluronic-b-poly(lactic acid) (PLA-F127-PLA) aggregates in aqueous solutions were reported previously to be vesicular nano-particles by our group. In the present study, we seek to investigate the feasibility of using PLA-F127-PLA vesicles as oral delivery carrier for insulin. Both in vitro and in vivo release behavior(More)
Poly(lactic acid) (PLA) was successfully grafted to both ends of Pluronic F127 block copolymer (PEO-PPO-PEO) to obtain amphiphilic PLA-F127-PLA block copolymers. The effect of enzymatic degradation on the release behaviors of hydrophobic model drug 9-(methylaminomethyl)anthracene (MAMA) from PLA-F127-PLA nano-particles with vesicular structure was studied(More)
Poly(lactic acid) (PLA) was successfully grafted to both ends of Pluronic F127 block copolymers (PEO-PPO-PEO) to obtain amphiphilic PLA-F127-PLA block copolymers. The block composition and structure of PLA-F127-PLA block copolymers were studied by nuclear magnetic resonance (NMR), gel permeation chromatography (GPC), differential scanning calorimetric (DSC)(More)
The first part of this article reviewed the applications of nanostructures derived from Pluronic block copolymers that have potentials in the field of biomedical sciences. Pluronic block copolymers are used not only in drug delivery systems but also in gene and cancer therapies. In the second part, the chemical modifications of Pluronic copolymers and their(More)
The interaction of pantoprazole to bovine serum albumin (BSA) has been investigated with and without four popular 5,7,3',4'-hydroxy-substituted flavonoids, quercetin, luteolin, taxifolin and (+)-catechin. The presence of flavonoids decreased binding constants of pantoprazole with BSA from 39.7% to 93.8%, which depended on flavonoid structures. Analysis of(More)
In order to prepare targeted drug carriers, previously a biotin group has been attached by our group to the end of Pluronic F87/poly(lactic acid) and Pluronic P85/poly(lactic acid) block co-polymers to obtain B-F87-PLA and B-P85-PLA, respectively. In this paper, the active targeting properties of B-F87-PLA and B-P85-PLA nanoparticles in vitro were(More)
Puerariae lobata flower (Willdenow) has a long history used to treat alcoholic intoxication in China, which contains a series of isoflavones as its chief pharmacologically active constituents. In this study, bovine serum albumin (BSA) functionalized iron oxide magnetic nanoparticles (Fe₃O₄ MNPs) coupled with high performance liquid chromatography-tandem(More)
Traditional activity-guided fractionation of natural products is a time-consuming, labor intensive, and expensive strategy, which cannot compete with high-throughput and rapid screening of natural products. Therefore, more efficient approaches are necessary for searching active compounds from natural products. Three main methods based on high-performance(More)
