Calcitriol-mediated modulation of urokinase-type plasminogen activator and plasminogen activator inhibitor-2
(Elsevier, 1991-02-15)
Calcitriol-induced differentiation of U937 mononuclear phagocytes is known to have divergent effects on the synthesis of urokinase-type plasminogen activator (uPA) and plasminogen activator inhibitor-2 (PAI-2). In this ...
Modeling of immunosensors under nonequilibrium conditions : II. Experimental determination of performance characteristics
(Elsevier, 1991-08-01)
In an attempt to optimize immunosensors operating with an immobilized antibody as binding protein and an analyte-enzyme conjugate as signal generator that is significantly larger in molecular size than the analyte, in a ...
Selective resonance enhanced multiphoton ionization of aromatic polymers in supersonic beam mass spectrometry
(Elsevier, 1991-07-15)
Various polymers have been studied using a pulsed laser evaporation method for volatilizing these species and entraining them into a supersonic jet expansion followed by resonance enhanced multiphoton ionization (REMPI) ...
Large-scale physical mapping within the region 22q12.3-13.1 in meningioma
(Elsevier, 1991-08)
The lack of physical mapping data strongly restricts the analysis of the meningioma chromosomal region that was assigned to the bands 22q12.3-qter. Recently, we reported a new marker D22S16 for chromosome 22 that was ...
Structure of the human cytochrome c oxidase subunit Vb gene and chromosomal mapping of the coding gene and of seven pseudogenes
(Elsevier, 1991-05)
Subunit Vb of mammalian cytochrome c oxidase (COX; EC 1.9.3.1) is encoded by a nuclear gene and assembled with the other 12 COX subunits encoded in both mitochondrial and nuclear DNA. We have cloned the gene for human COX ...
Synthesis of 4-Amino-1-([beta]-D-ribofuranosyl)pyrrolo[2,3-d]pyridazine; an entry into a novel series of adenosine analogs
(Elsevier, 1991)
The synthesis of a novel adenosine analog, 4-amino-1-([beta]-D-ribofuranosyl)pyrrolo[2,3-d]pyridazine, has been accomplished using pyrrole nucleoside precursors.
A class I jumping clone places the HLA-G gene approximately 100 kilobases from HLA-H within the HLA-A subregion of the human MHC
(Elsevier, 1991-08)
By the combination of cosmid cloning, chromosomal jumping, and pulsed-field gel electrophoresis (PFGE), we have fine-mapped the HLA-A subregion of the human major histocompatibility complex (MHC). Through the isolation of ...
Cellular morphogenesis in the Saccharomyces cerevisiae cell cycle: Localization of the CDC11 gene product and the timing of events at the budding site
(Wiley Subscription Services, Inc., A Wiley Company, 1991)
The Saccharomyces cerevisiae CDC3 , CDC10 , CDC11 , and CDC12 genes encode a family of homologous proteins that are not closely related to other known proteins [Haarer BK, Ketcham SR, Ford SK, Ashcroft DJ, and Pringle ...
The role of TNF in diverse pathologic processes
(Kluwer Academic Publishers; Springer Science+Business Media, 1991-04)
A molecular model for singlet/singlet energy transfer of monovalent ligand/receptor interactions
(Wiley Subscription Services, Inc., A Wiley Company, 1991-05)
A stochastic model is described that predicts the degree of singlet/singlet energy transfer in complexes formed between monovalent ligands and monovalent receptors. The modeling approach is intended to serve as an analytical ...
