The effect of heparin on the rate of binding of basic fibroblast growth factor (bFGF) to high affinity (receptor) and low affinity (heparan sulfate) binding sites on endothelial cells and CHO cells transfected with FGF receptor-1 or FGF receptor-2 was investigated. Radiolabeled bFGF bound rapidly to both high and low affinity sites on all three types of cells. Addition of 10 micrograms/ml hepar...
2634 for 44 Lunar and Planetary Science Conference (Houston, TX, March 18-22, 2013) STABILITY AND PHASE TRANSITION PATHWAYS OF OH-BEARING FERRIC SULFATES UNDER THE CONDITIONS RELEVANT TO DIURNAL, SEASONAL, AND OBLIQUITY CYCLES ON MARS. Yanli Lu and Alian Wang, Dept. of Earth and Planetary Sciences and the McDonnell Center for the Space Sciences, Washington University in St. Louis, One Brookings...
Heparan sulfate glycosaminoglycan, isolated from the cell surface of nonadhering murine myeloma cells (P3X63-Ag8653), does not bind to plasma fibronectin, but binds partially to collagen type I, as assayed by affinity chromatography with proteins immobilized on cyanogen bromide-activated Sepharose 4B. Identical results were obtained when myeloma heparan sulfate was cochromatographed, on the sam...
Epidemiological studies of particulate matter (PM) using central area monitors have associated total PM mass, as well as certain individual components of PM, including sulfate, with adverse human health effects. However, some recent studies that used concentrated ambient particles (CAPs) or analyzed the effects of air pollution from different sources or geographic areas suggest that while some ...
Proteoglycans have been extracted from rabbit corneal stromas at developmental stages from fetal to adult. Ion exchange fractionation and gel chromatography show that proteodermatan sulfates decrease in sulfation and relative amount and proteokeratan sulfates increase in sulfation and relative amount during development. There are small increases in size of all of the proteoglycans up to 2 weeks...
Two new complex copper(II) sulfates [Cu(1,10-phen)(H2O)2]SO4 (1, 1,10-phen = 1,10-phenanthroline) and [Cu(2,2′-bipy)(H2O)2]SO4 (2, 2,2′-bipy = 2,2′-bipyridine) have been hydrothermally synthesized and characterized by IR spectroscopy, elemental analysis, thermogravimetric analysis, and X-ray crystallography. 1 and 2 consist of complex cations [Cu(1,10-phen/2,2′-bipy)(H2O)2]2+ and SO42− anions, ...
Bioassay-guided separation of a lipophilic extract of the crinoid Alloeocomatella polycladia, inhibiting the activity of HCV NS3 helicase, yielded two groups of molecules: cholesterol sulfate and four new aromatic sulfates 1-4. The structures of the aromatics were elucidated by spectroscopic analysis in addition to theoretical studies. The aromatic sulfates 1-4 showed moderate inhibition agains...
