BACKGROUND Helicobacter infection is the main risk factor in developing gastric cancer. Mesenchymal stem cells (MSCs) are non-hematopoietic stromal cells, which are able to differentiate into different cell lineages. MSC contribute to cancer development by forming the tumor directly, contributing to the microenvironment, or by promoting angiogenesis and(More)
In this paper we describe our efforts for TREC contex-tual suggestion task. Our goal of this year is to evaluate the effectiveness of: (1) Preference crawling method that as far as possible to obtain more candidate spots' information from open-web to model the users' interest profiles; (2) Automatic summarization method that leverages the information from(More)
BACKGROUND Runt-related transcription factor 3 (RUNX3) is a member of the runt-domain family of transcription factors. Emerging evidence indicates that RUNX3 is a tumor suppressor gene in several types of human cancers including esophageal cancer. However, the association between RUNX3 promoter methylation and esophageal cancer remains unclear. Here we(More)
BACKGROUND/AIMS Stromal cells and the extracellular environment are vital to human tumors, influencing growth and response to therapy. Human tumor cell lines lack stroma and transplantation into immunodeficient mice does not allow meaningful analyses of the effects of stroma on tumor cell growth. Studies of xenografts of primary human tumor fragments in(More)
