LY2157299 (LY), which is very small molecule bringing high cancer diffusion, is a pathway antagonist against TGFβ. LY dosage can be diluted by blood plasma, can be captured by immune system or it might be dissolved during digestion in gastrointestinal tract. The aim of our study is to optimize a "nano-elastic" carrier to avoid acidic pH of gastrointestinal tract, colon alkaline pH, and anti-imm...
Abstract Background and Objectives Now day, using of stem cells and nanoparticles in the differentiation of stem cells is considered as a therapeutic approach. The purpose of this study was to synthesize and characterize nanocomposite polyacrylic polycarboxylic acid containing nanoparticles of biologically active glass 45S5 crushed and assessment effect of this composite on the propagation and...
Guided by theoretical ideas about the laws of radical chain polymerization processes, work was carried out to study influence parameters and conditions aquatic acrylic acid on suitability its polymer for therapeutic dentistry. These studies served as basis development patenting domestic technology production a ~ 40 % gel-like solution PAA, which is widely used both in Russia abroad dental filli...
In this research thin film heterogeneous cation exchange membrane was prepared by interfacial polymerization of polyacrylic acid-co-iron nickel oxide nanoparticle son PVC based substrate. Spectra analysis confirmed graft polymerization conclusively. The SEM images showed that polymerized layer covers the membranes by simple gel network entanglement. Results exhibited that membrane water content...
The photoswitching behavior of the polyacrylic acid (PAA) doped by methyl orange (MO) brush film was investigated using spectral analysis UV-Vis absorbance, Fourier Transformation Infrared spectroscopy, 2D electrical conductivity mapping and Atomic Force Microscopy. kinetics time evolution photoisomerization PAA-MO PEBs from E-state to Z-state UV-light irradiation, reverse thermal relaxation ex...
The aim of this study is to develop polymeric thin films for corrosion protection magnesium alloy AZ31. As polymer matrix, poly(4-vinyl pyridine) (P4VP) selected due its semiconducting properties and protonic conductivity. Polyacrylic acid tested as crosslinking layers improve interfacial adhesion. macroscopic the multilayer coatings are investigated by means electrochemical methods, such linea...
