Perfluorinated compounds (PFCs) including perfluorooctanoate (PFOA) and perfluorooctane sulfonate (PFOS) have been used in a wide range of industrial and consumer applications since 1960s. The previous studies have reported the occurrences of PFOS and PFOA in human blood and serum from various countries. In this study, 141 human whole blood samples(More)
Because of the disadvantages of invasive sampling, it is desirable to explore non-invasive matrices for human biomonitoring of perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA). The aim of this study was to evaluate the application of nail, hair and urine for human biomonitoring of PFOS and PFOA. The concentrations of PFOS and PFOA in(More)
This study was conducted to determine the human body burden of polybrominated diphenyl ethers (PBDEs) and then clarify the relationships between that and the disruption of thyroid hormones in the general population in Northern China. Between November 2010 and May 2011, 124 serum samples were obtained from volunteers from the provinces of Shanxi and(More)
BACKGROUND On the basis of SEER data, in which most gastric cancer patients had limited lymph node dissection, node ratio-based staging system (TNrM) has been shown to have better accuracy than the AJCC TNM system. This study is to validate the result with patients from Taiwan, where D2 lymphadenectomy is routinely performed. PATIENT AND METHOD A total of(More)
The determination of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans, and dioxin-like polychlorinated biphenyls in blood from a non-occupational population is essential for the investigation of adverse health effects from these pollutants. In this study, a sensitive method based on programmable-temperature vaporization with large-volume(More)
