BACKGROUND Multiple cellular functions are compromised in amyotrophic lateral sclerosis (ALS). In familial ALS (FALS) with Cu/Zn superoxide dismutase (SOD1) mutations, the mechanisms by which the mutation in SOD1 leads to such a wide range of abnormalities remains elusive. METHODOLOGY/PRINCIPAL FINDINGS To investigate underlying cellular conditions caused by the SOD1 mutation, we explored mut...
The present study investigated the development of crown and bridge resin using a new PNC-EMA monomer. M MA monomer has long been used for crown and bridge resins, but the polymer prepared with MMA monomer has certain demerits such as low mechanical strength and abrasion resistance. The authors prepared a polymer by mixing 3PNC-EMA monomer having a P=N bond in its skeleton, previously synthesize...
Effects of chain-end structure and residual metal compounds on thermal degradation of poly(epsilon-caprolactone) (PCL) were investigated by means of thermogravimetric and pyrolysis-gas chromatograph mass spectrometric analyses. Four types of PCL samples with different chain-end structures (alpha-carboxylic acid-omega-hydroxyl-PCL, alpha-dodecyl ester-omega-hydroxyl-PCL, alpha-carboxylic acid-om...
The morphological evolution of graft copolymer-based nano-objects was monitored by light scattering and electron microscopy during their formulation in water polymerization induced self-assembly using a photo-mediated reversible addition–fragmentation chain transfer mechanism. copolymer models used were composed dextran backbone bearing poly(2-hydroxypropyl methacrylate) grafts two degrees (X)....
A series of new polyamides containing maleimide pendant group were prepared by low temperature polycondensation of 5-(4-(2,5-dioxo-2H-pyrrol-1(5H)-yl)benzamido)isophthaloyl chloride as a new monomer with various aromatic diamines in NMP. Monomer and polymers structures were identified through FT-IR, 1H-NMR and elemental analysis. Obtained polymers were soluble in polar solvents and non solu...
A novel acrylate monomer containing 4H-pyran-4-one and 1,2,3-triazole ring, {1-[4-(4-oxo-6-phenyl-4H-pyran-2-yl)benzyl]-1,2,3-triazol-4-yl}methyl acrylate was synthesized by the reaction of 2-{4-[(4-(hydroxymethyl)-1,2,3-triazol-1-yl)methyl]phenyl}-6-phenyl-4H-pyran-4-one with acryloyl chloride in the presence of triethylamine. The structure of the acrylate monomer was established on the basis ...
