Iodine analysis of biological samples by neutron activation of 127I, with scintillation counting of cerenkov radiation
(Elsevier, 1971-03)
The naturally occurring isotope, 127I, has been measured by neutron activation, postirradiation extraction of 128I plus 127I (added carrier), and timed scintillation counting of aqueous solution utilizing Cerenkov radiation. ...
Measures of viability in isolated cells
(Elsevier, 1975-06)
Various methods were compared for estimation of cell viability. Cell count, uptake of trypan blue, release of cellular LDH, as well as cell contents of K+ and Na+ were determined in leukocytes, spleen cells, and Ehrlich ...
Selective catechol oxidations with diphenyl selenoxide. Applications to phenolic coupling.
(Elsevier, 1979)
Diphenyl selenoxide was used as a mild and selective oxidant in the synthesis of aporphines and homoaporphines. An intramolecular coupling between a phenol and a catechol is believed to proceed catechol selenurane intermediates.
Immunochemical studies of the combining sites of the two isolectins, A4 and B4, isolated from Bandeiraea simplicifolia
(Elsevier, 1979-11)
The specificity of two isolectins, A4 and B4, of Bandeiraea simplicifolia lectin I (BS-I) was studied by quantitative precipitin, precipitin inhibition, as well as by competitive binding assays using various blood group ...
Oxidation of 2-keto-4-hydroxyglutarate by pig heart and Escherichia coli [alpha]-ketoglutarate dehydrogenase complex
(Elsevier, 1979-01)
Enzyme preparations from pig heart and Escherichia coli have been found to catalyze a NAD+- and CoASH-dependent oxidation of 2-keto-4-hydroxyglutarate. Several independent lines of evidence indicate that 2-keto-4-hydroxyglutarate ...
Glassy Carbon low-temperature thermodynamic properties
(Elsevier, 1970-11)
The heat capacity of Glassy Carbon was measured by adiabatic calorimetry from 5 to 350 K and has no transitions or thermal anomalies. It parallels that of pyrolytic graphite annealed at 2600 [deg]C in showing an approximate ...
