You wrote that the U.S. beef is safe from mad cow disease, South Korea will allow U.S. beef imports. YES, very good; in this way, ten months ago I supported senator Nelson call about the disagreement with South Korea's restrictions on bone-in beef (http://www.bignewsnetwork.com /forum/showthread.php?t=9881). I described an alternative "BSE ammonia-magnesium" theory (http://www.agriworld.nl/feedm ix/headlines.asp?issue=3). This theory is based on the chronic Mg-deficiency- potentiated by hyperammonemia (high protein intake?). These mechanisms have a strong influence on CNS, especially in ruminants and carnivora animals (www.bse-expert.cz). Professor Brown, lecturer and researcher at the University of Bath, is another dissident scientist who believes the entire BSE/CJD link must be completely reconsidered. His research team recently found that elevated manganese (Mn) was associated with prion infection (http://jas.fass.org/cgi/conte nt/abstract/85/6/1596). However, these findings about "BSE; manganese theory"act in concert with my "BSE; ammonia- magnesium theory". So, I will perform some interpretations in my website with conclusion; why some central nervous system regions showed elevated Mn, other regions did not? and why the most consistent finding was an elevation of Mn in blood? However, in the first place, this will be published- presented at the 29th World Veterinary Congres (Vancouver, July 27-31, 2008), see article; Neurodegenerative Diseases and Schizophrenia as a Hyper or Hypofunction of the NMDA Receptors (http://www.meet-ics.com/wvac2 008/pdf/PS1-17Mar2008.pdf).
