Very recently, we confirmed 5-iodo-4-thio-2 -deoxyuridine (ISdU) as an efficient agent, increasing the extent of tumor cell killing with ionizing radiation. To our surprise, a similar derivative of 4-thio-2'-deoxyuridine, 5-bromo-4-thio-2 -deoxyuridine (BrSdU), does not show radio...
However, since the previous studies did not provide adequate explanations to why the correlation is time-varying, this paper proposes a hypothesis of 'key mediating factors'. We believe that: (1) although the price of crude oil and the dollar are influenced by different factors, such as ...
