Controlled Photoradical Polymerization Mediated by 2,2,6,6-Tetramethylpiperidine-1-Oxyl

Microencapsulation of Ethion by Interfacial Polymerization Utilizing Potassium Phthalimide-N-oxyl (PPINO) as a Promoter

Ring-opening polymerization-mediated controlled formulation of polylactide-drug nanoparticles.

We report here a unique method for formulating doxorubicin-polylactide (Doxo-PLA) conjugate nanoparticles, known as nanoconjugates (NCs), through Doxo/(BDI)ZnN(TMS)(2)-mediated [(BDI) = 2-((2,6-diisopropylphenyl)amido)-4-((2,6-diisopropylphenyl)-imino)-2-pentene], chemo- and regioselective polymerizations of lactide (LA) followed by nanoprecipitation. When Doxo/(BDI)ZnN(TMS)(2) was mixed with 1...

Controlled Radical Polymerization of methyl methacrylate and styrene mediated by a cobalt(II)-based initiatior system

The role of cobalt(II) complexes containing 2-formylpyrrolyl chelating ligands and phosphine ligands combined with a bromo-alkyl ester, an alkyl bromide or an azo compound in the formation of suitable initiator systems for vinyl monomer controlled radical polymerization was studied. The formation of syndiotactic-rich (Pr>0.7) poly(methyl methacrylate) (PMMA) and atactic (Pr=0.49) poly(styrene) ...

Induction of Heme Oxygenase -1 By Lipocalin 2 Mediated By Nf-Kb Transcription Factor

Purpose: Effect of lipocalin 2 on the expression of heme oxygenase I , II and NF-kB transcription factor was the purpose of this survey. Materials and Methods: Lcn2 was cloned to pcDNA3.1 plasmid by using genetic engineering method. The recombinant vector was transfected to CHO and HEK293T to establish stable cell expressing lipocalin 2. The presence of lipocalin 2 gene in these cells was confi...
