For quantitative data derived from the verbal autopsy, descriptive statistics were used to characterize the study sample, including primary caregiver's relationship, place where care was sought, number of contacts with formal health services, place of death, household socioeconomic status, marital status, education and age.
A frozen TMA containing 34 melanoma samples including primary tumors and metastases was stained by immunohistochemistry for TNW and TNC.
Human gastric tissue samples, including primary gastric tumor tissues, gastritis and normal stomach tissues, were obtained from Sir Run Run Shaw Hospital, Zhejiang University, Zhejiang, China.
Separately, comparisons within two groups of matched samples were performed, namely three complete matched samples, including primary melanoma, negative and positive SLN and seven negative SLN vs positive SLN matched pairs.
To clarify the relevance of EZH2 to human gastric carcinogenesis, EZH2 protein expression in human tissue samples, including primary gastric tumor tissues, gastritis and normal stomach tissues, was determined by immunohistochemical staining.
This region has been reported to be methylated in 70% of prostate cancer samples (including primary tissue and cell lines) analysed by Nelson et al (1997) but unmethylated in normal tissues.
The Stephens et al. [ 5] study is the first indication that genome-wide structural analysis of a relatively large number of samples, including primary tumors, is already an achievable goal.
The microarray data was verified by analysing a panel of RNA samples including primary CRC tumours, normal colon, CRC cell lines, PBMCs, immune cell lines and a fibroblast cell line for KLK6 mRNA levels using a qRT PCR assay that is specific and detects all known splice-forms of KLK6 mRNA.
Normal polarity ChRM directions in 35 samples include primary paleofield records as well as records of secondary magnetization.
Additional samples included primary cultures of human pancreatic duct cells, purified human islets from normal donors, and nine commercially available pancreatic cancer cell lines.
