To determine whether LOX-1 regulates neutrophil apoptosis and fungal load in A. fumigatus keratitis.Fas, FasL, CASP3, CASP8, CASP9 and BCL2 were tested in normal and infected corneas of C57BL/6 mic...

Based on the drinking water quality survey data of China's major cities, the existing disease burden calculation method was improved and disability-adjusted life years (DALYs) was taken as the end of evaluation to assess the health risk of arsenic contamination level. The results showed that the concentration of arsenic in drinking water of major cities in China was very low (0.53 μg·L

Nitrosamines such as nitrosodimethylamine(NDMA) in drinking water have recently attracted great attention because of their high carcinogenicity and high detection rate. Nitrosamines have also been repeatedly detected in drinking water in our country, leading to a lot of concerns about our drinking water safety. However, China has not yet formulated the relevant drinking water safety standards. In order to evaluate the health risks caused by NDMA in drinking water and to provide recommendations for the development of drinking water safety standards, the method of disability-adjusted life years(DALYs) and the two-stage disease model were used to estimate the health risk of liver cancer caused by intake of NDMA in drinking water. The data of this study were collected from two large-scale water quality surveys conducted in 35 cities in China from November 2009 to May 2012, and the detection conducted by Chen Chao

Nitrogen is often released in pulses with different frequencies, and N supply pulses may affect growth, reproduction, and biomass allocation of plants. However, few studies have examined how N supply pulses affect intraspecific competition of clonal plants and whether such an effect depends on the N supply amount. We grew one (no competition) or 12 ramets (with intraspecific competition) of both an invasive clonal plant Alternanthera philoxeroides and its native congener Alternanthera sessilis in five different N treatments: control (no N addition), low/high amount with low/high frequencies (pulses). Nitrogen addition significantly increased the growth of both species, while intraspecific competition decreased it. Nitrogen addition significantly increased intraspecific competitive intensity of A. philoxeroides as measured by the log response ratio of growth traits, but did not affect that of A. sessilis. Despite the N supply amount, N pulses had little effect on the growth and thus intraspecific competition of the two species. Therefore, increasing N deposition may change population structure and dynamics and the invasion succession of A. philoxeroides, but changes in N pulses may not.

To win the competitive advantage in market, more and more companies began to apply HR mobile technology. The paper from 7 dimension to design questionnaire, which include "administrative, workforce management, talent management, business intelligent, service delivery, workforce optimization and social media", choose different companies and industries to explore the present situation of the domestic application of HR mobile technology. Compared to the successful experience of foreign enterprises put forward the development trend of domestic enterprises in the future: extensive use of cloud technology to improve the business intelligence and service delivery contribution to the enterprise, adopt the way of renting service to improve the proportion of small and medium-sized enterprise to use HR mobile technology, use of technology and industry standards such as measures to ensure the security of data, improve the user experience to promote employee self-service system widely used.
