    Synthesis and properties of poly(ethylene glycol) macromer/β-chitosan hydrogels (1997)
    Springer
    Journal of materials science 8 (1997), S. 537-541 
    Details

    Topics: Medicine , Technology
    Notes: Abstract Semi-interpenetrating polymer network (semi-IPN) hydrogels composed of β-chitosan and poly(ethylene glycol) diacrylate macromer (PEGM) were synthesized and characterized for the application as potential biomedical materials. The mixture of PEGM and β-chitosan, dissolved in water including a small amount of acetic acid, was cast to prepare hydrogel films, followed by a subsequent crosslinking with 2,2-dimethoxy-2-phenylacetophenone as a non-toxic photoinitiator by ultraviolet irradiation. Photocrosslinked hydrogels exhibited relatively high equilibrium water content in the range 77–83% which is mainly attributed to the free water content rather than to the bound water, hydrogen bonded with components in semi-IPN hydrogels. The crystallinity, thermal properties and mechanical properties of semi-IPN hydrogels were studied. All the photocrosslinked hydrogels revealed a remarkable decrease in crystallinity. The glass transition temperatures, Tg, of crosslinked PEGM segment in semi-IPNs increased compared with poly(ethylene glycol) itself. However, with increasing β-chitosan content their Tg decreased owing to the higher degree of crosslinking. The tensile strengths of semi-IPNs in dry state were rather high, but those of hydrogels in wet state decreased drastically.

    Structure-property relationship of polyurethane ionomer (1992)
    Springer
    Colloid & polymer science 270 (1992), S. 956-961

    ISSN: 1435-1536
    Keywords: Polyurethaneionomer ; DMPA ; neutralization ; mechanicalproperties ; viscoelasticproperties

    Topics: Chemistry and Pharmacology , Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract Polyurethane (PU) ionomers were prepared using various types of polyol (PTAd, PCL, PTMG, and PPG) and isocyanate (MDI, HDI, and IPDI), together with different extender (DMPA) contents, degree of neutralization, and number average molecular weight (M n) of polyol. Modulus (E′), strength (σb), and glass transition temperature (T g) significantly increased with the increased amount of extender and extender neutralization. Among three of the iocyanate used, PU from MDI gave the highest modulus, strength, andT g. With regard to theM n of PTAd (600, 1000, 2000), PU from PTAd 600M n gave the highest modulus, strength, andT g, due probably to the highest hard segment content and phase mixing. On the other hand, PU from PTAd 2000M n gave significantly improved strength over PTAd 1000M n, and the highest elongation. The results were interpreted in terms of soft-segment crystallization, and soft-hard phase separation, which was concluded from the lowered softT g.

    The Brevibacterium albidum gene encoding the arginine tRNACCG complements the growth defect of an Escherichia coli strain carrying a thermosensitive mutation in the rnpA gene at the nonpermissive temperature (1997)
    Springer

    Notes: Abstract The Escherichia colirnpA gene encodes C5 protein, the protein component of RNase P. The rnpA49 mutation renders the C5 protein thermosensitive, which results in thermosensitivity of RNase P function. The chromosomal DNA region from Brevibacterium albidum that complements the rnpA49 mutation was analysed. The gene capable of complementing the growth defect of an rnpA49 mutant strain at nonpermissive temperature was identified as the gene for an arginine tRNA with anticodon CCG by a deletion analysis combined with complementation assays. Transcription of the arginine tRNA gene carried on a multicopy plasmid was correlated with the complementation of the rnpA49 mutation, indicating that the gene product is indeed responsible for complementation of the rnpA49 mutation.

    Dopa-responsive dystonia induced by a recessive GTP cyclohydrolase I mutation (1999)
    Springer
    Human genetics 〈Berlin〉 105 (1999), S. 226-230

    Notes: Abstract. GTP cyclohydrolase I (GTPCH) catalyzes the rate-limiting step of tetrahydrobiopterin (BH4) biosynthesis. GTPCH has been associated with two clinically distinct human diseases: the recessive hyperphenylalaninemia (HPA) and the dominant dopa-responsive dystonia (DRD). We found a recessive GTPCH mutation (R249 S, 747C→G) in a dystonia patient. Her PHA-stimulated mononuclear blood cells had a normal amount of GTPCH mRNA, but low GTPCH activity. Arginine 249 is located at the C-terminus of GTPCH, outside the catalytic site. E. coli expressed recombinant R249 S mutant protein possessed normal enzyme activity and kinetics. However, in transfected eukaryotic cells, R249 S mutant protein expression level was lower than the wild-type protein. Therefore, this is suspected to be a destabilizing mutation. Our data suggest that DRD could be either dominantly or recessively inherited, and the inheritance might be determined by the mechanism of mutation.

    Glucose-6-phosphatase gene mutations in Taiwan Chinese patients with glycogen storage disease type Ia (2000)
    Springer
    Journal of human genetics 45 (2000), S. 197-199

    Notes: Abstract Glycogen storage disease type Ia (GSD Ia) is caused by a deficiency of glucose-6-phosphatase (G6Pase) activity. Eighteen GSD Ia families were studied for G6Pase gene mutations. Thirty-two mutations were found in 36 GSD Ia chromosomes: 16 were 727 G→T (44.44%); 13 were R83H (327 G→T; 36.11%); 1 was 341delG; 1 was 933insAA; and 1 was 793 G→T. The 727 G→T and R83H mutations together accounted for 80.56% (29/36) of the GSD Ia chromosomes. These two mutations were easily examined by polymerase chain reaction-based methods, and the prenatal diagnosis of a non-affected fetus was successfully made. The 727 G→T mutation is the predominant mutation in Japanese GSD Ia patients, but is rarely seen in Western counties. The 727 G→T mutation is also the most prevalent mutation in Taiwan Chinese, although the incidence is not as high as in Japan.

    Rheological changes during the polymerization of polyurethane based interpenetrating polymer network(IPN) (1987)

    Notes: Experimental results on reactions forming polyurethanes and polyurethane-polyester Interpenetrating polymer network (IPN) are discussed with particular interest in rheological and kinetic changes before the gel point. In the IPN formation, viscosity rise is affected by the amount of styrene and polyester in the reaction system. Plots of reduced viscosity vs. conversion do not fall into a single curve. The results may be explained by the concept of having intra-molecular reaction or ring formation. The existence of hydroxyl group at the end of polyester molecule causes the graft reaction between the polyurethane phase and the polyester phase, which may speed up the viscosity rise of the reactive system. A simple method which based on rheological measurements only is proposed. This method of plotting reduced viscosity vs. reduced reaction time provides similar results as in the plots of reduced viscosity vs. conversion.
