Clinical Significance of Down-Regulated CD70 and CD27 Expression in Poor Prognosis of Esophageal Squamous Cell Carcinoma.

Introduction: CD27 is a co-stimulatory immune checkpoint molecule in the tumor necrosis factor receptor superfamily. CD27 regulates the generation and maintenance of T cell immunity by binding to CD70 and regulating B-cell activation and immunoglobulin synthesis.

Materials And Methods: CD27 and CD70 expression were assessed in esophageal squamous cell carcinoma (ESCC) compared to normal tissue samples in the GSE53625 dataset of 179 paired cases and in 153 Chinese cases using reverse transcription quantitative polymerase chain reaction (RT-qPCR) and immunohistochemistry.

[Research on the characteristics of Ulva prolifera in Shandong Peninsula during 2008-2012 based on MODIS data].

In the present study, the MODIS data were used to monitor the situation of Ulva prolifera in the Shandong Peninsula waters during the period of 2008-2012. Those studies mainly calculate the area of NDVI, and get the information of the time, area , scope , floating path of Ulva prolifera by using threshold segmentation method. The feasibility of monitoring Ulva prolifera information based on MODIS data and the macroscopic regularity of the outburst of Ulva prolifera was elementally studied.
