Activity and properties of CTP: Cholinephosphate cytidylyltransferase in adult and fetal rat lung
(Elsevier, 1976-08-23)
Cholinephosphate cytidylyltransferase (CTP: cholinephosphate cytidylyltransferase, EC 2.7.7.15) is located in both the microsomal and supernatant fractions of adult lung when the tissue is homogenized in 0.145 M NaCl. The ...
The effect of daily ingestion of caffeine on the microsomal enzymes of rat liver
(Elsevier, 1973-02)
The effect of repeated ingestion of caffeine on rat-liver microsoma enzymes was studied. In the rat, ingestion of 20-24 mg caffeine/kg/day in the drinking water for more than 2 wk inhibited aminopyrine N-demethylase activity. ...
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. ...
Acyl coenzyme a: 2-acyl-sn-glycerol-3-phosphate acyltransferase activity in rat liver microsomes
(Elsevier, 1971-11-05)
2-Acylglycerol-3-phosphate can be acylated by acyl-CoA in the presence of microsomal preparations from rat liver. With optimal amounts of substrate, the acyltransferase reaction to the 1-position occurred at about one tenth ...
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 ...
Finite nucleus model for the Fermi contact interaction
(John Wiley & Sons, Inc., 1979-01)
A model for the Fermi contact interaction is proposed in which the charge and magnetic moment of the nucleus are uniformly distributed within a sphere of radius r 0 . This leads to a SchrÖdinger equation, which is solvable ...
Steady-state kinetic analyses of Photosystem II activity catalyzed by lipophilic electron acceptors
(Elsevier, 1979-08-14)
Steady-state kinetic analyses of the Photosystem II activity elicited by quinones and quinonediimines in KCN/Hg-inhibited chloroplasts reveal that: 1. 1. Quinones generate a single reaction in which one quinone competes ...
On the exactness of classical transition state theory for collinear collisions
(Elsevier, 1977-06-15)
We have applied Pechukas and McLafferty's test for the exactness of classical transition state theory (TST) to the collinear subsurface of Porter and Karplus' H3 hypersurface and have determined that TST is exact to at ...
