Fluorographic detection of radioactivity in polyacrylamide gols with the water-soluble fluor, sodium salicylate
(Elsevier, 1979-09-15)
Sodium salicylate has been found to serve as a satisfactory fluor for enhanced detection of radioactivity in polyacrylamide gels. The compound is inexpensive, water soluble, penetrates rapidly into gels, and gives linearity ...
Tumor localizing agents. IX. Radioiodinated cholesterol
(Elsevier, 1970)
19-Iodocholesterol-125I was synthesized for study as a possible agent for photoscanning the adrenal gland and associated tumors. In contrast to previous radioiodinated steroids, it was found to be much less prone to rapid ...
Heat capacities and thermodynamic properties of ammonium and potassium thiocyanates from 5 to 340 K
(Elsevier, 1970-05)
The heat capacities of ammonium and potassium thiocyanates were determined by adiabatic calorimetry over the range 5 to 340 K, and associated thermodynamic functions were computed from the results. At 298.15 K, the heat ...
Tris(hydroxymethyl)aminomethane. Heat capacities and thermodynamic properties from 5 to 350 K
(Elsevier, 1972-05)
Heat capacities of crystalline or , (HOCH2)3CNH2, were measured from 5 to 350 K by adiabatic calorimetry. No thermal anomalies were found in this region. The observed heat capacities yield for Cp(298.15 K), So(298.15 ...
Prostaglandin biosynthesis can be triggered by lipid peroxides
(Elsevier, 1979-04-01)
Studies of ferriheme cyclooxygenase, using two different assay systems, show that a variety of peroxides can trigger a rapid acceleration of cyclooxygenase activity to produce prostaglandins. Lipid hydroperoxides formed ...
Anions and the contraction of glycerol-extracted muscle fibers
(Elsevier, 1970-01)
Glycerinated rabbit psoas fibers 5-19 days old were immersed in contracting solutions with and without varying concentrations of different sodium salts. Raising the pH of the solution in small steps identified a threshold ...
