Multifunctional Injectable Hydrogel Loaded with Cerium-Containing Bioactive Glass Nanoparticles for Diabetic Wound Healing.

Diabetic foot wound healing is a major clinical problem due to impaired angiogenesis and bacterial infection. Therefore, an effective regenerative dressing is desiderated with the function of promoting revascularization and anti-bacteria. Herein, a multifunctional injectable composite hydrogel was prepared by incorporation of the cerium-containing bioactive glass (Ce-BG) into Gelatin methacryloyl (GelMA) hydrogel.

Polycaprolactone/gelatin degradable vascular grafts simulating endothelium functions modified by nitric oxide generation.

Host remolding with scaffolds degradation and rapid formation of a complete endothelium, are prospective solutions for improving performance of small diameter vascular grafts. For this purpose, microfibrous polycaprolactone (PCL)/gelatin scaffolds were prepared by electrospinning and subsequently functionalized with heparin and organoselenium-immobilized polyethyleneimine for nitric oxide generation through layer-by-layer self-assembly. Our results showed that modified PCL/gelatin grafts had strong catalytic nitric oxide generation capacity and facilitated the enhanced attachment of endothelial cells, compared with control scaffold groups.

[Two Data Inversion Algorithms of Aerosol Horizontal Distributiol Detected by MPL and Error Analysis].

Atmospheric aerosols have important impacts on human health, the environment and the climate system. Micro Pulse Lidar (MPL) is a new effective tool for detecting atmosphere aerosol horizontal distribution. And the extinction coefficient inversion and error analysis are important aspects of data processing.

[A new retrieval method for ozone concentration at the troposphere based on differential absorption lidar].

Aerosols interfere with differential absorption lidar ozone concentration measurement and can introduce significant errors. A new retrieval method was introduced, and ozone concentration and aerosol extinction coefficient were gained simultaneously based on the retrieval method. The variables were analyzed by experiment including aerosol lidar ratio, aerosol wavelength exponent, and aerosol-molecular ratio at the reference point.

[Influence of high humidity in summer on the characteristic of aerosol's size distribution in Beijing].

In order to research the effect of high humidity on the growth of aerosol particles, the APS, TEOM and BC instruments were used to monitor the aerosol in Beijing during August, 2007. The results show that, under steady-state weather condition, the correlation coefficient between the mass concentration of PM10 and BC aerosol is 0.82, but the correlation between the number concentration and the mass concentration of PM10 is not in accordance with that under non-steady-state weather condition.
