Vibrational analysis of crystalline diketopiperazine--II. Normal mode calculations
(Elsevier, 1984)
Based on our Raman and i.r. [1] data and assignments for DKP and five of its isotopic derivatives, we have refined an intramolecular force field in a non-redundant basis. This analysis shows that the cis peptide group may ...
Proteomics FASTA Archive and Reference Resource
(WILEY-VCH Verlag, 2008-05)
A FASTA file archive and reference resource has been added to ProteomeCommons.org. Motivation for this new functionality derives from two primary sources. The first is the recent FASTA standardization work done by the Human ...
Synthesis of flexible ligands for assembling two metals in close proximity. Magnetic, electrochemical and spectral properties of binuclear copper (II) complexes with different exogenous bridging motifs
(Kluwer Academic Publishers; Springer Science+Business Media, 2003-04)
Binuclear Cu II complexes having new flexible heptadentate ligands 2,6-bis{[bis(3,3′- N , N -dimethylaminopropyl)amino]methyl}-4-bromophenol [HL 1 ], 2,6-bis(3,3′- N , N -dimethylaminopropyl)amino]methyl}-4-methylphenol ...
Association of calmodulin inhibition, erythrocyte membrane stabilization and pharmacological effects of drugs
(Elsevier, 1982-11-08)
The present study was designed to determine whether there is an association of drug-induced inhibition of calmodulin functions, drug-induced membrane stabilization (protection against osmotic lysis), and pharmacological ...
Transtubular bioreactor: A perfusion device for mammalian cell cultivation
(Kluwer Academic Publishers; Science & Technology Letters ; Springer Science+Business Media, 1989-01)
A transtubular mammalian cell perfusion chamber has been developed that allows separate delivery and control of medium and gas flow to the cells. The hydrodynamic and mass transfer characteristics of the reactor are studied ...
Sedimentation behavior of solubilized gonadotropin receptor from plasma membranes of bovine corpus luteum
(Elsevier, 1976-03-25)
The gonadotropin receptors associated with plasma membrane fractions were solubilized by detergents, including Triton X-100, Lubrol WX, Lubrol PX and sodium deoxycholate before and after equilibration with 125I-labelled ...
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 ...
