The two 99mTc-complexes were prepared with high radiochemical purity and had good stability. The partition coefficient results indicated both of them were hydrophilic, and cellular uptake studies showed they exhibited good hypoxic selectivity. From the biodistribution study results, 99mTcO-NMXT showed more favourable tumor uptake (1.73 ± 0.14 ID%/g) and higher tumor/muscle ratio (7.01 ± 0.16) than 99mTcN-NMXT at 4 h post-injection. Single photon emission computed tomography (SPECT) imaging study of 99mTcO-NMXT showed there was a visible accumulation in tumor site, suggesting it would be a promising candidate as a tumor hypoxia imaging agent.As Traditional Chinese Medicine (TCM) transcends its cultural boundaries and becomes widely used in many countries around the world, one of the major risks to the growing use of TCM internationally is the damage caused to its reputation and to community safety when TCM practitioners are not adequately trained. Ensuring the quality and competency of TCM practitioners is a fundamental requirement. This paper covers (1) the current level of regulation of education and training of TCM practitioners particularly in countries with well developed health systems; (2) the progress of self regulatory standards for education and training developed by international organizations and (3) the potential role of ISO/TC 249 in assisting these initiatives.Childhood obesity is a major health concern in the United States (US) and those living in rural communities are at higher risk than their urban counterparts. Few prevention trials have engaged whole families of school-age children in community settings, and none to date have promoted family meals, family activity and healthful home environments in rural settings through a rigo
