The microwave spectrum and structure of the furan [middle dot] sulfur dioxide complex
(Elsevier, 1992)
The microwave spectrum of furan [middle dot] sulfur dioxide complex has been observed with a pulsed molecular beam Fourier transform microwave spectrometer. Transitions having a-, b-, and c-dipole selection rules were all ...
The gene for a novel epidermal antigen maps near the neurofibromatosis 1 gene
(Elsevier, 1992-10)
Recently the M17S1 gene, encoding an epidermal antigen thought to play a role in cell adhesion, was mapped to chromosome bands 17q11-q12, placing it in the vicinity of the gene for the genetic disorder neurofi-bromatosis ...
A microsatellite polymorphism associated with the PLC1 (phospholipase C) locus: Identification, mapping, and linkage to the MODY locus on chromosome 20
(Elsevier, 1992-07)
A highly polymorphic (dC-dA)n[middle dot](dG-dT)n dinucleotide repeat at the PLC1 locus on human chromosome 20 has been identified. Primers flanking the dinucleotide repeat were used for PCR amplification of the repeat ...
Molybdenum/cobalt/sulfur clusters: Models and precursors for hydrodesulfurization (HDS) catalysts
(John Wiley & Sons Ltd., 1992-09)
Sulfido clusters which incorporate molybdenum and a late transition metal, e.g. iron, cobalt or nickel, are readily prepared by the reactions of Cp 2 Mo 2 S 4 , Cp 2 Mo 2 S 2 (SR) 2 or Cp 2 Mo 2 (CO) 2 (SR) 2 with Fe 2 ...
DNA-binding and non-DNA-binding forms of the transformed glucocorticoid receptor
(Elsevier, 1992-03)
In this work we have probed the mechanism responsible for two non-DNA-binding states of the mouse glucocorticoid receptor. In the first case, transformed receptors were treated with hydrogen peroxide. It is known that ...
Subset-specific co-stimulatory signals are required for IL-2 production but not growth inhibition responses by T cell hybrids specific for myelin basic protein
(Elsevier, 1992-03)
Two distinct types of T cell hybridomas (designated THYB-1 and THYB-2) were derived by fusing BW5147 thymoma cells with encephalitogenic T helper cells from Lewis rats. Both subsets required MHC-restricted presentation of ...
Topical delivery of liposomally encapsulated gamma-interferon
(Elsevier, 1992-06-15)
The extent of uptake of gamma interferon ([gamma]-IFN) in various strata of hairless mouse, human and hamster skin upon application of a liposomal formulation and an aqueous solution were determined by in vitro diffusion ...
Rapid communication : Inhibition of adenosine deaminase by azapurine ribonucleosides
(Elsevier, 1992-11-03)
We have synthesized several 8-azapurine nucleosides as inhibitors of adenosine deaminase. The presence of a nitrogen on the imidazole ring decreased the Ki value for nebularine by 100-fold but did not lower the Ki value ...
CD28 and staphylococcal enterotoxins synergize to induce MHC-independent T-cell proliferation
(Elsevier, 1992-11)
The bacterial exotoxins staphylococcal enterotoxin A and B (SEA and SEB) mediate disease through their effects on T lymphocytes. In this manuscript we have demonstrated that both SEA and SEB can directly activate purified ...
Synthesis of high-affinity, hydrophobic monosaccharide derivatives and study of their interaction with concanavalin A, the pea, the lentil, and fava bean lectins
(Elsevier, 1992-12)
Concanavalin A (Con A) and agglutinins from the pea (PSA), lentil (LCH), and fava bean (VFA) constitute a group of -mannose/-glucose binding legume lectins. In addition to their sugar binding specificity, these lectins ...
