α- d -Galactosylation of surface fucoglycoconjugate(s) upon stimulation/activation of murine peritoneal macrophages
(Kluwer Academic Publishers; Chapman & Hall ; Springer Science+Business Media, 1992-04)
Murine resident macrophages express, on their surface, carbohydrate epitopes which undergo changes during their stimulation/activation as monitored by binding of 125 I labelled Evonymus europaea and Griffonia simplicifolia ...
Rheological behavior of solutions of amphiphilic acrylic copolymers in mixed solvents
(Wiley Subscription Services, Inc., A Wiley Company, 1996-06-13)
A descriptive model was developed, using viscometry and light scattering, that explains the anomalous rheological behavior of solutions of amphiphilic acrylic copolymers upon the addition of water. The rheological behavior ...
Synthesis and physical properties of N -substituted polyimides based on imidazole
(John Wiley & Sons, Inc., 1993-09)
AB-type monomers based on imidazole for the preparation of polyimides were synthesized by carrying out a substitution at the 1-position of 2-amino-4,5-dicyanoimidazole, followed by hydrolysis. Thus, pendant groups such as ...
Antibody-antigen complex formation with immobilized immunoglobulins
(Elsevier, 1992-08-15)
We have investigated the complex formation between an immobilized monoclonal antibody and antigens that differ in size about 50-fold. As a model system, we used an iodinated progesterone derivative and a progesterone-horseradish ...
Preparation of polyfunctional diorganomercurials and their transmetallation to diorganozincs. Applications to the preparation of optically active secon
(Elsevier, 1992-10-13)
Two new methods of preparation of functionalized diorganomercurials have been developed. The first method involves a substitution reaction of (ICH2 Their transmetallation with zinc dust (toluene, 80[deg]C, 3-5 h) affords ...
Carbohydrate-binding specificity of the daffodil (Narcissus pseudonarcissus) and amaryllis (Hippeastrum hybr.) bulb lectins
(Elsevier, 1990-06)
The carbohydrate binding specificity of the daffodil (Narcissus pseudonarcissus; NPA) and amaryllis (Hippeastrum hybr.; HHA) lectins, isolated from extracts of their bulbs by affinity chromatography on immobilized mannose, ...
Report On ‘Comprehensive Curricular Change at a Small Liberal Arts College: Bioorganic First at Juniata College’
(Springer-Verlag; Springer-Verlag New York, Inc., 1998-02)
Because the conceptual basis of the curriculum is that the majority of the students are not chemists, participants in this session examined which aspects of organic chemistry are really necessary for a nonchemical (mostly ...
Defect interactions on solid surfaces
(Elsevier, 1993-03-10)
A unified approach to the calculation of the elastic interaction between defects on a surface that describe, for example, steps, islands, and stress domains is presented. This is accomplished by determining the spatial ...
Characterization and regulation of phosphatidylglycerolphosphate phosphatase in Saccharomyces cerevisiae
(Elsevier, 1990-09-18)
Phosphatidylglycerophosphatase (EC 3.1.3.27) activity was characterized in mitochondrial extracts from Saccharomyces cerevisiae. The enzyme has a pH optimum of 5.5. Maximum activity occurs in the presence of Triton X-100 ...
