Interaction of Artepillin C with model membranes

Pazin, Wallance Moreira; Olivier, Danilo da Silva; Vilanova, Neus; Ramos, Ana Paula; Voets, Ilja Karina; Soares, Ademilson Espencer Egea; Ito, Amando Siuiti

Green propolis, a mixture of beeswax and resinous compounds processed by Apis mellifera, displays several pharmacological properties. Artepillin C, the major compound in green propolis, consists of two prenylated groups bound to a phenyl group. Several studies have focused on the therapeutic effects of Artepillin C, but there is no…

Semifluorinated alkanes and alkanes: A phase study of the perfluorohexyloctane – Tetradecane system

Runnsjö, Anna; Kocherbitov, Vitaly; Graf, Gesche; Pettigrew, Anthony; Scherer, Dieter; Mortensen, Kell; Engblom, Johan

The binary system perfluorohexyloctane (F6H8)–tetradecane (C14) was investigated in order to increase understanding of interactions of semifluorinated alkanes (SFAs) with hydrophobic molecules. The thermal phase behavior for F6H8 and C14 and their mixtures was determined using DSC. The activity coefficients for both components in the mixtures were calculated and Gibbs…

Compatibility and epitaxial crystallization between Poly(ethylene) and Poly(ethylene)-like polyesters

Pepels, Mark P. F.; Kleijnen, Rob G.; Goossens, Johannes G. P.; Spoelstra, Anne B.; Tandler, Renate; Martens, Hans; Soliman, Maria; Duchateau, Rob

This work describes the phase behavior of blends of ‘polyethylene-like’ polypentadecalactone (PPDL) and polyethylene. Blends of high-density polyethylene (HDPE) and PPDL were shown to be immiscible at the onset of crystallization of polyethylene, resulting in phase-separated morphologies. However, epitaxial crystallization of PPDL onto the HDPE crystals was observed by transmission…

Extended Law of Corresponding States Applied to Solvent Isotope Effect on a Globular Protein

Bucciarelli, Saskia; Mahmoudi, Najet; Casal-Dujat, Lucía; Jéhannin, Marie; Jud, Corinne; Stradner, Anna

Investigating proteins with techniques such as NMR or neutron scattering frequently requires the partial or complete substitution of D₂O for H₂O as a solvent, often tacitly assuming that such a solvent substitution does not significantly alter the properties of the protein. Here, we report a systematic investigation of the solvent…

On the dissolution state of cellulose in cold alkali solutions

Hagman, Joel; Gentile, Luigi; Jessen, Christian Moestrup; Behrens, Manja; Bergqvist, Karl-Erik; Olsson, Ulf

We have characterized the dissolved state of microcrystalline cellulose (MCC) in cold alkali solutions using a combination of small angle X-ray (SAXS) and static light scattering (SLS), 11^1H NMR, NMR self-diffusion, and rheology experiments. NMR and SAXS data demonstrate that the cellulose is fully molecularly dissolved. SLS, however, shows the…

Deformation mechanisms in ionic liquid spun cellulose fibers

Wanasekara, Nandula D.; Michud, Anne; Zhu, Chenchen; Rahatekar, Sameer; Sixta, Herbert; Eichhorn, Stephen J.

The molecular deformation and crystal orientation of a range of next generation regenerated cellulose fibers, produced from an ionic liquid solvent spinning system, are correlated with macroscopic fiber properties. Fibers are drawn at the spinning stage to increase both molecular and crystal orientation in order to achieve a high tensile…
