  • Background Reducing geographical inequalities in cancer survival in England was a key aim of the Calman-Hine Report (1995) and the NHS Cancer Plan (2000). (bmj.com)
  • This study assesses whether geographical inequalities changed following these policy developments by analysing the trend in 1-year relative survival in the 28 cancer networks of England. (bmj.com)
  • Reducing regional inequalities in cancer survival in England was identified as a public health priority in two key policy documents relating to cancer services in England: the Calman-Hine Report of 1995 and the NHS National Cancer Plan of 2000. (bmj.com)

  • In the study, we used weighted gene co-expression network analysis to construct a co-expression network to screen out highly prognostic immune-related genes. (techscience.com)
  • Motivation for this study was to highlight the emerging role of deep learning in the field of precision medicine and suggest an expanding utility for computational analysis of histology in the future practice of pathology. (laurentian.ca)
  • In this study, we investigated gene expression changes at 2 and 6 days post inoculation (dpi) at day 21 with a lentogenic NDV in a commercial egg-laying chicken hybrid using RNA sequencing analysis. (escholarship.org)
