Human neutrophil protein kinase C: calcium-induced changes in the solubility of the enzyme do not always correlate with enzymatic activity
(Elsevier, 1988-07-29)
We hypothesized that calcium and 1,2-diacylglycerols stimulated human neutrophil (PMN) protein kinase C (EC 2.7.1.37) in a two-step mechanism. The proposed mechanism entails (1) increased insoluble protein kinase C activity ...
Plane-stress crack-tip fields for perfectly plastic orthotropic materials
(Kluwer Academic Publishers; Springer Science+Business Media, 1988-10)
Plane stress mode I crack-tip fields for perfectly plastic orthotropic materials are studied. Plastic orthotropy is described by Hill's quadratic yield function. The construction of crack-tip fields is based on the general ...
A practical large scale chemical synthesis of chiral glycines
(Elsevier, 1988)
(R)- and (S)-[2-2H]glycine of high chiral purity were synthesized in large quantities in [approximate] 40% overall yield from readily available starting materials via a totally chemical procedure. Reduction of either ...
Expert system for interpretation of the infrared spectra of environmental mixtures
(Elsevier, 1988)
A program for the identification of the principal components of mixtures through interpretation of the infrared mixture spectrum (IntIRpret) was developed. This program, which was developed as a preliminary screening tool ...
1,4-Additions of the highly functionalized copper reagents RCu(CN)ZnI [middle dot] 2 BFP3 to trisubstituted enones. A new BF3 promoted cyclization reaction
(Elsevier, 1988)
The new copper reagents RCu(CN)Zn I [middle dot] 2 BF3 1 containing various functional groups like esters, cyanides, chlorides or enoates react with [beta], [beta]'- disubstituted enones to afford the Michael adducts 4-7 ...
