Folate and UVB Papers in Pdf Format

Here are my old papers, with the diagrams included, in pdf format. I now think that reduced folates, such as L-leucovorin (L-folinic acid) and L-methylfolate, are far superior to folic acid, for many reasons, but the concepts discussed in the folic acid paper are still "valid." Here's the paper on folate metabolism in relation to purine and pyrimidine metabolism (http://www.mediafire.com/?zmfojwc4am2), and here's the paper on the effects of cutaneous UVB/UVA exposure on sensory neurons and projection neurons/wide-dynamic-range neurons in the dorsal horn and caudal trigeminal nucleus, etc. (http://www.mediafire.com/?410jmzmrjjm).
