THE "CATFISH EFFECT" OF THE PRIVATE SECTOR ON THE ECONOMY OF THE PEOPLE'S REPUBLIC OF CHINA
In: Journal of enterprising culture: JEC, Volume 4, Issue 4, p. 331-349
ISSN: 0218-4958
Just as a catfish placed in a tank will by its vigorous activity oxygenate the water and energise the other fish, so the private sector1 in the People's Republic of China (PRC) is stimulating progress in other aspects of the economy. It is suggested that the changes, which include the creation of a new entrepreneurial class; setting a model for "capital operations" in the transition to a market economy; accelerating the formation of a competitive climate and acting as a pioneer, are contributing greatly to the development of the PRC. The paper concludes that the private sector provides a new dynamic force and is unlikely to be abolished again.

Magnetosomes are protein-rich membrane nanoparticles which are synthesized by magnetic bacteria; these have gained a lot of attention owing to their unique magnetic and biochemical characteristics. Nevertheless, whether bacterial magnetosomes have a corona after interacting with the plasma, and how such a corona affects nanoparticle–cell interactions is yet to be elucidated. The aim of this study was to characterize corona formation around a bacterial magnetosome and to assess the functional consequences.Methods: Magnetosomes were isolated from the magnetotactic bacteria, M. gryphiswaldense (MSR-1). Size, morphology, and zeta potential were measured by transmission electron microscopy and dynamic light scattering. A quantitative characterization of plasma corona proteins was performed using LC-MS/MS. Protein absorption was further examined by circular dichroism and the effect of the corona on cellular uptake was investigated by microscopy and spectroscopy.Results: Various serum proteins were found to be selectively adsorbed on the surface of the bacterial magnetosomes following plasma exposure, forming a corona. Compared to the pristine magnetosomes, the acquired corona promoted efficient cellular uptake by human vascular endothelial cells. Using a protein-interaction prediction method, we identified cell surface receptors that could potentially associate with abundant corona components. Of these, one abundant corona protein, ApoE, may be responsible for internalization of the magnetosome-corona complex through LDL receptor-mediated internalization.Conclusion: Our findings provide clues as to the physiological response to magnetosomes and also reveal the corona composition of this membrane-coated nanomaterial after exposure to blood plasma.Keywords: LC-MS/MS, cellular interaction, cellular uptake, biogenic magnetic nanoparticle
