The investigation of alleged insecticide toxicity: a case involving chlordane exposure, multiple sclerosis, and peripheral neuropathy

A man with no previous medical problems had two documented exposures to an insecticide containing the organophosphorous compounds chlordane and heptachlor. Six months to one year later, he began to experience neurological symptoms which progressed until his death. At autopsy, his brain showed classic findings of multiple sclerosis, and he had a severe peripheral neuropathy. Review of the literature indicates that the findings are not compatible with chlordane toxicity. Some of the factors to be used in determining the casual relationship between toxic exposure and disease processes are discussed.     

Determination of ABO blood group markers in single hair segments

Determination of ABO-blood group on human hair segments of 79 individuals was performed by means of modified Yada absorption-elutions technique. The studies were carried out with 4 micron thin cross sections of hair. In 79% of the cases it was possible to establish the correct blood group. Individual hair segments of 0.5 cm length yielded reliable results. Antigen identification was best with blood group B and most difficult of the AB type.     

Why Not Invade North Korea? Threats, Language Games, and U.S. Foreign Policy

International relations theory has difficulty explaining how similar policies produce different outcomes. Iraq and North Korea have been identified as members of the "axis of evil" with weapons of mass destruction programs that threaten the United States. Yet in late 2002, the United States prepared to attack Iraq whereas it chose to negotiate with North Korea, even after North Korea admitted to a secret nuclear program in direct violation of its 1994 agreement with the United States. Moreover, a direct comparison with Iraq shows North Korea to possess the greater material capability to threaten the United States. I argue that a language-based constructivist approach can explain these differences in U.S. foreign policy where other theoretical approaches cannot. By examining the U.S. entanglement in intersected language games—the implementation of the 1994 Agreed Framework with North Korea and the enforcement of United Nations Resolutions in Iraq—it becomes possible to show how the United States could construct North Korea's nuclear program as a manageable threat that could be dealt with diplomatically.
