CCK antagonists reveal that CCK-8 and JMV-180 interact with different sites on the rat pancreatic acinar cell CCKA receptor
(Elsevier, 1994)
The ability of CCKA antagonists to inhibit full and partial CCK agonists of the rat pancreatic acinar cell CCKA receptor has been studied. When isolated rat pancreatic acini were superfused with CCK-8 (10 pM-1 nM) or CCK-4 ...
Interaction of five -mannose-specific lectins with a series of synthetic branched trisaccharides
(Elsevier, 1991-06-25)
The interaction of a series of synthetic, branched trisaccharides with five -mannose-specific lectins was studied by precipitation-inhibition assay. The branched methyl [alpha]--mannotrioside, [alpha]--Manp-(1-->3)-[[ ...
Boron-modified polysilylcarbodi-imides as precursors for Si–B–C–N ceramics: Synthesis, plastic-forming and high-temperature behavior
(John Wiley & Sons, Ltd., 1998-10)
The synthesis, by two different reaction pathways, of boron-modified polysilylcarbodi-imides of general type {B[C 2 H 4 Si(R)NCN] 3 } n (R 14=singly bonded organic ligand) and the plastic-forming and the thermal behavior ...
Topological studies of spinach 22 kDa protein of Photosystem II
(Elsevier, 1994-12-30)
An intrinsic 22 kDa polypeptide is associated with the O2-evolving Photosystem II core complex in a variety of green plants, although it does not appear to be required for O2 evolution. Digestion of thylakoid membranes and ...
cDNA and derived amino acid sequence of rabbit nasal cytochrome P450NMb (P450IIG1), a unique isozyme possibly involved in olfaction
(Elsevier, 1991-02-15)
Olfactory-specific cytochrome P450NMb was previously purified to electrophoretic homogeneity from microsomes of rabbit nasal mucosa in this laboratory. In the present study, a cDNA library made from poly(A)+ RNA from rabbit ...
The sampling properties of some distance geometry algorithms applied to unconstrained polypeptide chains: A study of 1830 independently computed conformations
(Wiley Subscription Services, Inc., A Wiley Company, 1990-10)
In this paper we study the statistical geometry of ensembles of poly(L-alanine) conformations computed by several different distance geometry algorithms. Since basic theory only permits us to predict the statistical ...
Actin polymerization in cellular oxidant injury
(Elsevier, 1991-08-01)
Microfilaments undergo an ATP-dependent disruption into shortened bundles following cellular exposure to oxidants. This phenomenon does not require a net change in the amount of polymerized actin. However, increased amounts ...
Progress in Practice: Exploring the Cooperative and Collaborative Dimensions of Group Learning
(Springer-Verlag; Springer-Verlag New York, Inc., 1996-03)
We all participate in a variety of groups as part of our daily lives, from families to social and work communities. As chemists, we are part of our college departments, our professional societies, our research groups, and ...
Thermodynamics of iron sulfides I. Heat capacity and thermodynamic properties of Fe9S10 at temperatures from 5 K to 740 K
(Elsevier, 1991-03)
Measurements of the heat capacity of Fe9S10 over the temperature range 5 K to 740 K reveal a first-order structural transition at 495 K and two higher-order transitions with maxima at 534 K and 591 K. The last two are of ...
