Adhesion of RBL-2H3 mucosal mast cells to fibronectin-coated surfaces has been linked to changes in secretion and tyrosine kinase activity. We now show that adhesion affects the sensitivity of RBLâ€¦ (More)

Many numerical methods call for repeated calculatmn of the first partial derivatives of a given function of several variables. Errors m a program for that calculatmn can be hard to discover. Aâ€¦ (More)

The rat basophilic leukemic (RBL-2H3) cell line was stably transfected with the endogenously expressed Ca2+-dependent protein kinase C-alpha (PKC-alpha) and -betaI and the Ca2+-independent delta andâ€¦ (More)

An algorithm is described for finding the minimum of any convex, not necessarily differentiable, function f of several variables. The algorithm yields a sequence of points tending to the solution ofâ€¦ (More)
