Biogenetic Autonomy of Mitochondria and Its Limits
The past ten years have seen such an almost explosive growth of efforts devoted to studies on mitochondrial biogenesis that they occupy at least as much contemporary journal space as do studies on mitochondria...

Improvement of the CuZn-superoxide dismutase enzyme activity and stability as a therapeutic agent by modification with polysialic acids
The optimal process for the polysialylation reaction was as follows: polysialicacid (PSA) was activated by periodate oxidation, then coupled to CuZn superoxide dismutase (SOD) with a PSA:SOD molar ratio of 40:...

A new polysialic acid production process based on dual-stage pH control and fed-batch fermentation for higher yield and resulting high molecular weight product
To determine the factors influencing the resulting molecular weight of polysialic acid (PSA), batch fermentations by using Escherichia coli were conducted. It was found that temperature and pH were significant fa...
