Proteomics of DF-1 cells infected with avian leukosis virus subgroup J.

Avian leukosis virus subgroup J (ALV-J) is an avian oncogenic retrovirus that has led to severe economic losses in the poultry industry in China in recent years. The pathogenesis of virus infection and virus-host interactions are still not well elucidated. In this paper, we investigated the expression changes for cellular proteins in DF-1 cells infected with ALV-J.

[Study of the microwave emissivity characteristics over different land cover types].

The microwave emissivity over land is very important for describing the characteristics of the lands, and it is also a key factor for retrieving the parameters of land and atmosphere. Different land covers have their emission behavior as a function of structure, water content, and surface roughness. In the present study the global land surface emissivities were calculated using six month (June, 2003-August, 2003, Dec, 2003-Feb, 2004) AMSR-E L2A brightness temperature, MODIS land surface temperature and the layered atmosphere temperature, and humidity and pressure profiles data retrieved from MODIS/Aqua under clear sky conditions.
