Synthesis of cyclic and polymeric derivatives of 1,2-dithiol-o-carborane
(Elsevier, 1983-01-18)
Cyclic compounds containing two symmetrically placed 1,2-dicarbaclosododecaboranyl or two 7,8-dicarbaundecaborate(10) moieties have been synthesized. The bridges between the carborane cages are S---S or S---CH2---CH2---S ...
The macrophage adherence phenomenon: Its relationship to prostaglandin E2 and superoxide anion production and changes in transmembrane potential
(Elsevier, 1983-12)
Mononuclear phagocytes are undoubtedly the sine qua non of chronic inflammatory reactions. This is demonstrated by their unique ability to function as phagocytic, secretory, or effector cells during the course of an immune ...
Mixing of phases in non-crystalline materials: Application to carbon
(Elsevier, 1983-09-01)
The atomic structure of non-crystalline solids is described by the correlation function. When more than one phase is present, the simple addition of the correlation functions for the various phases in proportion to their ...
The stability of SiO-based ceramics containing ZRO2 and other oxides
(Elsevier, 1983)
Calculations of thermochemical equilibria, using the program SOLGASMIX, have defined the conditions and compositions of SiO-based ceramics in which stable ZrO2 particles can be obtained. The results are compared with ...
Pyrrolopyrimidine nucleosides 19. A total synthesis of the nucleoside antibiotic cadeguomycin [2-amino-7-([beta]-d-ribofuranosyl)-pyrrolo[2,3-]pyrimidin-4-one-5-carboxylic acid]
(Elsevier, 1983)
A total synthesis of 2-amino-7-([beta]-D-ribofuranosyl)pyrrolo[2,3-]pyrimidin-4-one-5-carboxylic acid has been accomplished and confirms the previous structural assignment for the nucleoside antibiotic cadeguomycin.
Multiple scattering in small-angle neutron scattering measurements on polymers
(Elsevier, 1983-02)
Multiple scattering corrections in small-angle neutron scattering experiments on polymers have been examined. Numerical calculations show that, for typical experimental conditions, the second-order scattering is less than ...
A further investigation of the stannic chloride-catalyzed condensation reaction of 1-hexene and 1,2,3,5-tetra-O-acyl-[beta]--ribofuranoses
(Elsevier, 1983-04-16)
The reaction of 1-hexene with either 1-O-acetyl-2,3,5-tri-O-benzoyl-[beta]--ribofuranose (5b) or 1,2,3,5-tetra-O-acetyl-[beta]--ribofuranose (5a) in the presence of stannic chloride leads to the formation of a complex ...
Solubilization and partial purification of dihydroxyacetone-phosphate acyltransferase from guinea pig liver
(Elsevier, 1983-10-01)
Dihydroxyacetone-phosphate:acyl coenzyme A acyltransferase (EC 2.3.1.42) was solubilized and partially purified from guinea pig liver crude peroxisomal fraction. The peroxisomal membrane was isolated after osmotic shock ...
Enzyme-linked lectin assay (ELLA): Use of alkaline phosphatase-conjugated Griffonia simplicifolia B4 isolectin for the detection of [alpha]--galactopyranosyl end groups
(Elsevier, 1983-04-15)
Alkaline phosphatase has been coupled to Griffonia simplicifolia I B4 isolectin using a one-step glutaraldehyde conjugation procedure. This enzyme-lectin conjugate (AP-GS I-B4) has been used to specifically detect plastic-bound ...
