Analysis of Cu2+ adsorption on cell surface of a Gram-negative bacterium P. putida 5-x was carried out. Isolated cell envelopes possess fivefold more Cu2+ adsorption capacity than that of the fresh intact cells. Experimental results also indicate that the content of the peptidoglycan layer, the outer membrane and inner membrane in the cell envelope is in(More)
The discharge of recombinant DNA waste from biological laboratories into the eco-system may be one of the pathways resulting in horizontal gene transfer or "gene pollution". Heating at 100 degrees C for 5-10 min is a common method for treating recombinant DNA waste in biological research laboratories in China. In this study, we evaluated the effectiveness(More)
The rapid development of science and technology has brought a lot of convenience to the industry, and allowed companies to enhance their competitive advantages in the market. However, at some point in the growth stage, companies often reach a bottle neck of efficiency and effectiveness in production due to a saturated scale of economy, leading managers to(More)
The development of curative glioblastoma treatments and tumour-specific contrast agents that can overcome the blood–brain barrier (BBB) and infiltrative tumour morphology remains a challenge. Apolipoprotein E3 (apoE3) is a high density lipoprotein apolipoprotein that chaperones the transcytosis of nanoparticles across the BBB, and displays high-affinity(More)
