Some recent developments in the preparation of polymeric reagents and their use in various chemical reactions are described. Improved polymeric acyl transfer reagents were prepared. They possess good mechanical properties and are therefore easy to handle and pure products are obtained by their use. With one of these polymeric reagents pure peptides may be obtained in high yield in reactions las...

Biodegradable poly(L-lactic acid) (PLA) fibrous scaffolds were prepared by electrospinning from a PLA melt containing poly(ethylene glycol) (PEG) as a plasticizer to obtain thinner fibers. The effects of PEG on the melt electrospinning of PLA were examined in terms of the melt viscosity and fiber diameter. Among the parameters, the content of PEG had a more significant effect on the average fib...

Composite fibrous membranes based on poly(ɛ-caprolactone) (PCL) and mesoporous bioactive glass nanoparticles (MBGNs) were fabricated by electrospinning. MBGNs Zn-doped prepared microemulsion sol–gel method successfully incorporated inside the polymeric fibers of 240 385 nm in diameter for undoped PCL_MBGNs fibers, respectively. Thermal analysis showed that concentration reached a maximum around...

The study is oriented at the in vitro evaluation of the immunobiological activity and efficacy of synthetically prepared isomeric pentasaccharides representing fragments of Aspergillus fumigatus cell-wall galactomannan and containing β-(1→5)-linked tetragalactofuranoside chain attached to O-6 (GM-1) or O-3 (GM-2) of a spacer-armed mannopyranoside residue. These compounds were studied as biotiny...

Electrospinning is an inexpensive and versatile technique for fabricating micro- nano- scaled fibers. There have been limited attempts to employ it the fabrication of thermochromic (TC) fibers, a three-component (dye, developer, solvent) TC material has required use more complicated coaxial electrospinning technique. Herein, simple novel method creating fibers by single strands poly (methyl met...
