A Micromethod for the Determination of Bradykininogen in Blood Plasma
BRADYKININOGEN is the inactive precursor from which bradykinin, the hypotensive and smooth-muscle stimulating nonapeptide, can be released by the action of trypsin1. The concentration of the precursor in blood ca...

Solubility of manganese, iron, and zinc as affected by application of sulfuric acid to calcareous soils
Four calcareous Arizona soils were treated with sulfuric acid applied to varying degrees of saturation of the acid titratable basicity of the soils. At less than 100% saturation there was a significant increas...

Measurement of Optical Dephasing by Spectral Holeburning in Rare Earth Doped Inorganic Glasses
Spectral hole burning has been observed in rare earth doped silicate glasses, and used to measure homogeneous linewidths (Γh). For Eu3+, holes are burned by optical pum** of nuclear quadrupole levels, and our l...

A Reevaluation of EBV-Specific T Cell-Mediated Immunity in Malaria-Endemic and Non-Endemic Regions of Papua, New Guinea
Various theories have been advanced to explain the association between holoendemic malaria and EBV in the induction of Burkitt’s lymphoma (BL). One possibility is that malaria may act by suppressing the EBV-sp...
