Conversion to Ca2+-Independent Form of Ca2+/Calmodulin Protein Kinase II in Rat Pancreatic Acini
(Elsevier, 1994-02-28)
CCK rapidly converted Ca2+/calmodulin kinase II (CaMK II) to a Ca(2+)-independent form with peak action at 30 sec followed by decline to the basal level at 10 min. The threshold concentration of CCK for this action was 30 ...
Maximization of Daily Canopy Photosynthesis: Effects of Herbivory on Optimal Nitrogen Distribution
(Elsevier, 1994-08-07)
Recent models have shown that higher leaf nitrogen concentration per unit area maximizes nitrogen use efficiency with increasing light intensity. As a result, total canopy photosynthesis is maximized when nitrogen ...
CFTR Does Not Alter Acidification of L Cell Endosomes
(Elsevier, 1994-11-30)
Endosomes from L cells, transduced with the CFTR gene, and the parental line, which does not express detectable levels of CFTR, were loaded with FITC-dextran, isolated and the initial rates of acidification, steady-state ...
