BACKGROUND and Aims The four cultivated Erythroxylum taxa (E. coca var. coca, E. novogranatense var. novogranatense, E. coca var. ipadu and E. novogranatense var. truxillense) are indigenous to the Andean region of South America and have been cultivated for folk-medicine and, within the last century, for illicit cocaine production. The objective of this research was to assess the structure of g...
Members of the Plasmodium falciparum var gene family encode clonally variant adhesins, which play an important role in the pathogenicity of tropical malaria. Here we employ a selective panning protocol to generate isogenic P.falciparum populations with defined adhesive phenotypes for CD36, ICAM-1 and CSA, expressing single and distinct var gene variants. This technique has established the frame...
The arginine-rich fraction of calf thymus histone (histone B) exerts bactericidal activity on various coliform bacilli and micrococci under certain conditions in vitro. Final concentrations of less than 1 microg. histone per ml. kill susceptible microbes without detectable morphological alteration or lysis. Among the microorganisms highly susceptible to histone are Escherichia, Salmonella, Shig...
Lymphopoiesis was studied in 3-month-old normal C57Bl mice and in 3-month-old C57Bl mice carrying from 12 to 48 C57Bl thymus grafts using tritiated thymidine labeling. Thymus graft lymphopoiesis was found to be identical with that of normal thymus tissue and the presence of thymus grafts was found to have no influence on host thymus lymphopoiesis. No evidence was found that the massive amounts ...
The one-seeded, serrate leaf margined junipers of Southwestern United States and northern Mexico consist of J. angosturana, J. californica, J. coahuilensis var. arizonica, J. c. var. coahuilensis, J. monosperma, J. pinchotii, J. occidentalis var. australis, J. o. var. occidentalis and J. osteosperma. Recent nrDNA and trnC-trnD sequence data were compared with RAPDs analysis and two of the taxa ...

Antibodies to purified calf thymus Fl, and to chromatographically purified subfractions of calf thymus Fl histones were induced by immunization of rabbits with histone-RNA complexes. Complement fixation studies with these antibodies demonstrated structural differences between the subfractions in one organ and between those of different organs and species. The anti-F1 sera showed varying reactiv...
Some Angelica species are used for medicinal purposes. In particular, the roots of Angelica acutiloba var. acutiloba and A. acutiloba var. sugiyamae, known as “Toki” and “Hokkai Toki”, respectively, are used as important medicinal materials in traditional Japanese medicine. However, since these varieties have recently outcrossed with each other, it is difficult to determine whether the Japanese...
Event risk is the risk that a portfolio’s value can be affected by large jumps in market prices. Event risk is synonymous with “fat tails” or “jump risk”. Event risk is one component of “specific risk,” defined by bank supervisors as the component of market risk not driven by market-wide shocks. Standard Value-at-Risk (VaR) models used by banks to measure market risk do not do a good job of cap...
