O n a mission, I entered the Ezra Jack Keats archives in de Grummond Children’s Literature Collection at University of Southern Mississippi (USM) early 2011. Chosen by Foundation Executive Director Deborah Pope and Curator Ellen Ruffin to do research for things include Viking’s fiftieth anniversary edition Keats’ iconic The Snowy Day , searched items that would be meaningful an extra eight-page...

[Photo by Dave Rumbach]______________________________ KNOCK, Ireland (AP) Pope John Paul II took his peace pilgrimage yesterday to Ire­ land’s most sacred shrine, in the bogs of Coun y Mayo,and in a forceful denunciation of ter­ rorism declared, “ Murder is murder, no matter what...

Adverse health effects of ambient air pollution on mortality and morbidity in adults and children have been extensively studied across the world (Barnett et al. 2006; Bell et al. 2004; Dominici et al. 2003; Gold et al. 1999; Jerrett et al. 2005; Middleton et al. 2008; Pope 1999; Pope et al. 1991; Pope and Kanner 1993; Samoli et al. 2007; Wietlisbach et al. 1996). Considerable consistency across...

The Pope and Stevens method (1) for quantitative determination of amino acids and peptides is based on iodometric analysis of the combined copper, a procedure that is somewhat inconvenient. Woiwood (a), using the color produced by diethyldithiocarbamate, has described a spectrophotometric modification of the Pope and Stevens method. Martin and Mittelmann (3) have used polarographic analysis of ...

Supported lipid bilayers composed of 1-palmitoyl-2-oleoyl-phosphatidylethanolamine (POPE) and 1-palmitoyl-2-oleoyl-phosphatidylglycerol (POPG) were assembled by the vesicle fusion technique on mica and studied by temperature-controlled atomic force microscopy. The role of different physical parameters on the main phase transition was elucidated. Both mixed (POPE/POPG 3:1) and pure POPE bilayers...

Liposome aggregation is a major problem associated with the covalent attachment of proteins to liposomes. This report describes a procedure for coupling proteins to liposomes that results in little or no change in liposome size. This is achieved by incorporating appropriate levels of poly(ethylene glycol)-modified lipids into the liposomes. The studies employed thiolated avidin-D coupled to lip...

Prior studies have shown that the biological mixture of the two hydrophobic surfactant proteins, SP-B and SP-C, produces faster adsorption of the surfactant lipids to an air/water interface, and that they induce 1-palmitoyl-2-oleoyl phosphatidylethanolamine (POPE) to form inverse bicontinuous cubic phases. Previous studies have shown that SP-B has a much greater effect than SP-C on adsorption. ...

The peptide-lipid interaction of a beta-hairpin antimicrobial peptide tachyplesin-1 (TP-1) and its linear derivatives are investigated to gain insight into the mechanism of antimicrobial activity. (31)P and (2)H NMR spectra of uniaxially aligned lipid bilayers of varying compositions and peptide concentrations are measured to determine the peptide-induced orientational disorder and the selectiv...
