Agriculture faces great challenges to ensure global food security by increasing yields while reducing environmental costs. Here we address this challenge by conducting a total of 153 site-year field experiments covering the main agro-ecological areas for rice, wheat and maize production in China. A set of integrated soil-crop system management practices(More)
Icaritin (ICT) is a hydrolytic form of icariin isolated from plants of the genus Epimedium. This study was to investigate the radiosensitization effect of icaritin and its possible underlying mechanism using murine 4T1 breast cancer cells. The combination of Icaritin at 3 µM or 6 µM with 6 or 8 Gy of ionizing radiation (IR) in the clonogenic assay yielded(More)
Air and soil pollution from traffic has been considered as a critical issue to crop production and food safety, however, few efforts have been paid on distinguish the source origin of traffic-related contaminants in rice plant along highway. Therefore, we investigated metals (Pb, Cd, Cr, Zn and Cu) concentrations and stable Pb isotope ratios in rice plants(More)
BACKGROUND Pretreatment hematological markers of inflammatory response have emerged as prognostic factors for patients with cancer. In this study, we evaluated the prognostic significance of various hematologic parameters in patients with nasopharyngeal carcinoma (NPC). METHODS Clinical data from 251 patients with NPC were retrospectively collected.(More)
Tylvalosin, a new broad-spectrum, third-generation macrolides, may exert a variety of pharmacological activities. Here, we report on its anti-oxidative and anti-inflammatory activity in RAW 264.7 macrophages and mouse treated with lipopolysaccharide (LPS) as well as piglet challenged with porcine reproductive and respiratory syndrome virus (PRRSV).(More)
Vitamin C and thiol agents improve vasomotor function. To determine whether these compounds directly affect endothelial function, nitric oxide (NO) synthesis was measured in human aortic endothelial cells treated with ascorbic acid or the thiol modulating agents lipoic acid or L-2-oxothiazolidine-4-carboxylic acid (OTC). A dose-dependent increase in(More)
The development of potent, orally bioavailable, and selective series of 5-amino-3-hydroxy-N(1-hydroxypropane-2-yl)isothiazole-4-carboxamidine inhibitors of MEK1 and MEK-2 kinase is described. Optimization of the carboxamidine and the phenoxyaniline group led to the identification of 55 which gave good potency as in vitro MEK1 inhibitors, and good oral(More)
Mineral cycling plays a critical role in wetland ecosystem functions and can be affected by environmental changes, such as CO2 enrichment. Learning the responses of mineral bioavailability in wetlands to elevated CO2 under field conditions will provide enormous benefits to the assessment of climate change impacts on wetland ecosystems. A free-air CO2(More)
The Fyn related kinase (FRK), a member of intracellular Src-related tyrosine kinases, was recently reported to function as a potent tumor suppressor in several cancer types. However, the expression level and functional significance of FRK in human malignant glioma, which is characterized by high migration and invasion potential, have never been(More)
