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...

This article focuses on Guercino’s Return of the Prodigal Son, commissioned in name Cardinal Alessandro Ludovisi and his marketing choices. is a case study terms self-promotion tactics employed by an ambitious artist. My argument that one finds painting secondary more sophisticated level interpretation, which relates to relationship between painter patron. To most traditional iconography scene,...


 „Liturgical tradition” is a living form that expresses the Apostolic Tradition, which unchanging deposit of Revealed Divine Truths. After Second Vatican Council, liturgical tradition was included in books 1962 has been maintained on certain rules. The discipline celebrating this liturgy changed depending attitude pope. possibility it gradually restored. Eventually, Pope Benedict XVI sanc...

We consider the (1, 0) supersymmetric Yang-Mills multiplet coupled to a self-dual tensor multiplet in six dimensions. It is shown that the counterterm required to cancel the one-loop gauge anomaly modifies the classical equations of motion previously obtained by Bergshoeff, Sezgin and Sokatchev (BSS). We discuss the supermultiplet structure of the anomalies exhibited in the resulting equations ...

The fresco cycle painted at the behest of Pope Sixtus IV in the late 1470s in the main ward of the hospital of Santo Spirito in rome comprises an extended pictorial biography of Sixtus, prefaced by scenes representing the legendary foundation of the hospital by his predecessor Innocent III. The legend, which tells how Innocent established Santo Spirito as a foundling hospital in response to the...
