Magnetic properties of some new polymeric chelating complexes. I.

A new series of metallopolymer complexes derived from the homopolymer poly(2‐acrylamide) benzoic acid (PBA) through some transition metals, Cu(II), Ni(II), and Co(II), were prepared. The compounds were synthesized and characterized through different techniques. Their molecular structures were assumed based on the different spectral data [ultraviolet (UV) and infrared (IR)]. The magnetic behavior of these metallopolymer complexes was measured as a function of magnetic field strength [1.65–0.85 tesla (T)] at room temperature (RT) (300 K) and as a function of temperature (4.2–300 K) at a magnetic field strength of 1.7 T. Based on the magnetic data, the mechanisms of magnetic interaction are explained and related to the stereochemistry of these metallopolymer complexes. © 1999 John Wiley & Sons, Inc.

Mutation breeding of nuclease p1 production in <Emphasis Type="Italic">Penicillium citrinum</Emphasis> by low-energy ion beam implantation

Nuclease p1 is an important enzyme in the nucleotide industry that is used to hydrolyze nucleic acid into nucleotides. To improve enzyme activity, Penicillium citrinum, a nuclease p1 producing strain, was mutated by low-energy Nitrogen ion beam implantation at an energy level of 15 keV and a dose ranging from 1×10¹⁵–1×10¹⁶ ions/cm². The mutant strain designated as N409 was obtained with a high yield of nuclease p1. The activity of nuclease p1 was 421 U/mL from the mutant strain N409, which was increased by 86% compared with the control. The fermentation kinetics of nuclease p1 by the mutant strain N409 was studied in a 30 L external airlifting bioreactor. A model was proposed using the logistic equation for microbial growth, the Luedeking-Piret equation for product formation and a Luedeking-Piret-like equation for substrate uptake. The results predicted from the model were in good agreement with the experimental observations.     

Fabrication and Evaluation of Polycaprolactone–Poly(hydroxybutyrate) or Poly(3‐Hydroxybutyrate‐co‐3‐Hydroxyvalerate) Dual‐Leached Porous Scaffolds for Bone Tissue Engineering Applications

Polycaprolactone (PCL) blend with poly(hydroxybutyrate) (PHB) or poly(3‐hydroxybutyrate‐co‐3‐hydroxyvalerate) (PHBV) dual‐leached scaffolds are prepared by using the solvent casting and salt–polymer‐leaching technique. The blending of the PHB and PHBV in PCL scaffolds results in decreased porosities of the scaffolds, and the water absorption capacities of the scaffolds also decrease. The compressive modulus of the PCL–PHB and PCL–PHBV dual‐leached scaffolds is greatly increased by the blending of PHB or PHBV matrix. An indirect cytotoxicity evaluation of all scaffolds with mouse fibroblastic cells (L929) and mouse calvaria‐derived preosteoblastic cell (MC3T3‐E1) indicates that all dual‐leached scaffolds are posed as nontoxic to cells. Both PCL–PHB and PCL–PHBV dual‐leached scaffolds are supported by the attachment of MC3T3‐E1 at significantly higher levels to tissue culture polystyrene plate (TCPS) and are able to support the proliferation of MC3T3‐E1 at higher levels to that cells on TCPS and PCL scaffolds. For mineralization, cells cultured on surfaces of PCL–PHB and PCL–PHBV dual‐leached scaffolds show higher mineral deposition than on TCPS and PCL scaffold.
