Crystallization and Preliminary X-ray Diffraction Analysis of CsaA from P. torridus: A Chaperone Rarely Found in Archaea

13-Jun-2017 | Sharma, Archana; K. Pal, Ravi; Goel, Manisha, Chemical Biology, 2017

Abstract: Background and Objective: CsaA is a molecular chaperone known to prevent aggregation of preproteins and also involved in the post-translational translocation of the proteins across the cytoplasmic membrane after correct folding. CsaA is known to be present in prokaryotes but is ...

Alzheimer's Disease-associated Aβ42 Peptide: Expression and Purification for NMR Structural Studies

13-Jun-2017 | Serra-Batiste, Montserrat; Garcia-Castellanos, Raquel; Ninot-Pedrosa, Marti; Serra-Vidal, Bernat; Simon Berrow, Nich ..., Chemical Biology, 2017

Abstract: Background: The aggregation of the amyloid-beta peptide (Aβ) in the brain is strongly associated with Alzheimer's disease (AD). However, the heterogeneous and transient nature of this process has prevented identification of the exact molecular form of Aβ responsible for the ...

Marine Drugs, Vol. 15, Pages 140: Cereus sinensis Polysaccharide and Its Immunomodulatory Properties in Human Monocytic Cells

18-May-2017 | Wu, Junwen ; Zhou, Xuefei ; Zhang, Min ; Yao, Yun ; Han, Juanjuan ; Liu, Kehai, Marine Drugs, 2017

In this study, the extraction conditions of the crude polysaccharide from Cereus sinensis were optimized by response surface methodology. The optimum extraction conditions were: a ratio of raw material to water volume of 1:80 (g/mL); an extraction temperature of 72 °C; and an extraction time of 3 ...

Characterization and quantitation of PVP content in a silicone hydrogel contact lens produced by dual‐phase polymerization processing

16-May-2017 | Andrew J. Hoteling, William F. Nichols, Patricia S. Harmon, Shawn M. Conlon, Ivan M. Nuñez, Joseph Hoff, Orlando M. ..., Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2017

Abstract Polyvinylpyrrolidone (PVP) has been incorporated over the years into numerous hydrogel contact lenses as both a primary matrix component and an internal wetting agent to increase lens wettability. In this study, complementary analytical techniques were used to characterize the PVP ...

Exploring Tyrosine‐Triazolinedione (TAD) Reactions for the Selective Conjugation and Cross‐Linking of N‐Carboxyanhydride (NCA) Derived Synthetic Copolypeptides

29-Mar-2017 | Saltuk B. Hanay, Bas Ritzen, Dermot Brougham, Aylvin A. Dias, Andreas Heise, Macromolecular Bioscience, 2017

Highly efficient functionalization and cross‐linking of polypeptides is achieved via tyrosine‐triazolinedione (TAD) conjugation chemistry. The feasibility of the reaction is demonstrated by the reaction of 4‐phenyl‐1,2,4‐triazoline‐3,5‐dione (PTAD) with tyrosine containing block copolymer ...

Physicochemical Characterization of the Shell Composition of PBCA‐Based Polymeric Microbubbles

29-Mar-2017 | Lia Appold, Yang Shi, Stephan Rütten, Alexander Kühne, Andrij Pich, Fabian Kiessling, Twan Lammers, Macromolecular Bioscience, 2017

Microbubbles (MB) are routinely used as contrast agents for ultrasound (US) imaging. In recent years, MB have also attracted interest as drug delivery systems. Soft‐shelled lipidic MB tend to be more advantageous for US imaging, while hard‐shelled polymeric MB appear to be more suitable for drug ...
