[Carbon Stability of Biochar and Its Effects on Soil Organic Carbon Mineralization in Coastal Wetlands].

Biochar has a significant influence of both enhancing carbon sequestration in coastal wetlands and reducing greenhouse gas emissions. However, the carbon sequestration potential of biochar and the pathways that influence soil organic carbon （SOC） mineralization are still unclear. Biochar carbon stability experiments revealed the carbon sequestration potential of biochar prepared using different pyrolysis temperatures.

Enhanced photocatalytic disinfection of P. expansum in cold storage using a TiO2/ACF film.

Spores of Penicilliumexpansum are the most important airborne component of fungal contamination and are commonly present in the moist air in cold storage rooms where fruits and vegetables are stored. To improve the ability of activated carbon felt-supported titanium dioxide (TiO2/ACF) to remove spores of P. expansum from the atmosphere, measurements for the removal efficiency of the spores at a temperature of 3 degrees C+/-1 degrees C and relative humidity of 90%+/-3% had been made on photocatalytically-activated (PC) silver-doped TiO2/ACF prepared by ion sputtering in two different modes and photoelectrocatalytically-activated (PEC) TiO2/ACF films.

Hydroxysafflor yellow A protects neuron against hypoxia injury and suppresses inflammatory responses following focal ischemia reperfusion in rats.

Previous data demonstrated that hydroxysafflor yellow A (HSYA), a yellow color pigments extracted from the safflower, was an effective agent against focal cerebral ischemia. In the present study we demonstrated that HSYA prevented the injury in cultured cerebral cortical neurons induced by oxygen-glucose deprivation and increased the cell viability, as shown by the inhibition of both LDH and NO efflux. Further, HSYA administered orally 3 d before middle cerebral artery occlusion has the capacity to reduce cerebral infarct size and edema after 2 h cerebral ischemia followed by 24 h reperfusion in rats, and to significantly improve neurological behavior scores.
