Reactive oxygen species (ROS) actively participate in microglia-mediated pathogenesis as pro-inflammatory molecules. However, little is known about the involvement of specific antioxidants in maintaining the microglial oxidative balance. We demonstrate that microglial peroxiredoxin (Prx) 5 expression is up-regulated by lipopolysaccharide (LPS) through(More)
Glutamate-mediated excitotoxicity, which is associated with reactive oxygen species (ROS), is hypothesized to be a major contributor to pathological cell death in the mammalian central nervous system, and to be involved in many acute and chronic brain diseases. Here, we showed that isoliquiritigenin (ISL) isolated from Glycyrrhiza uralensis (Gu), one of the(More)
By generating and examining transgenic tomato overexpressing ath-miR399d grown in hydroponic conditions, in quartz sand, or in a polytunnel greenhouse vegetable soil culture, this study aimed to investigate the effects of miR399d from Arabidopsis on phosphorus (P) accumulation, P concentrations in transgenic tomato overexpressing ath-miR399d shoots,(More)
Little is known about effects of high nitrogen (N) fertilization on soil chemical properties, enzyme and microbial activities involved in N and C transformation. Soil EC, pH, mineral N, three enzyme activities, nitrification capacity, and microbial functional diversity were evaluated under conventional N rate (270 or 300 kg  N  ha−1 season−1, N4), 80% (N3),(More)
Vegetables provide an important source of selenium (Se) for many regions of China. Excess nitrogen (N) fertilizers are commonly used for vegetable production. In this regard, the effect of inorganic N-fertilizer application on the Se content in soils and plants was evaluated in vegetables produced in a polytunnel greenhouse vegetable system. Vegetables were(More)
Impacts of biochar application mode on nitrogen (N) leaching, ammonia (NH3) volatilization, rice grain yield and N use efficiency (NUE) are not well understood. Therefore, a field experiment was conducted to evaluate those impacts in a rice paddy soil received 225 kg N ha-1 from either urea or N-rich wastewater. One treatment received 10 t ha-1 biochar with(More)
It is of great concern that nitrogen-rich (N-rich) wastewater irrigation increases ammonia (NH3) volatilization from rice (Oryza sativa L.) paddy fields. A pilot-scale field trial was conducted to study the impact of different management practices on reducing NH3 volatilization and their subsequent impacts on nitrous oxide (N2O) emission from a paddy field(More)
Nutrient losses from greenhouse vegetable production systems may impair water quality in the Taihu Lake Region of China. We studied the characteristics of nitrogen (N) lost via runoff from greenhouse vegetable systems and strategies for minimizing N entering water bodies. A two-year experiment at a field scale was conducted to monitor N surface runoff. An(More)
Discharge of nitrogen (N) from fertilizers applied to vegetables is becoming a serious environmental problem. In a field experiment involving a celery-tomato-fallow-lettuce rotation, leaching was the primary pathway of N loss (56.1±0.4% of the total), followed, in descending order, by runoff (11.7±0.3%), N2O emissions (1.6±0.1%), and volatilization of(More)
Efficient and precise yield prediction is critical to optimize cabbage yields and guide fertilizer application. A two-year field experiment was conducted to establish a yield prediction model for cabbage by using the Greenseeker hand-held optical sensor. Two cabbage cultivars (Jianbao and Pingbao) were used and Jianbao cultivar was grown for 2 consecutive(More)
