23-11-2014 | Author(s): Yamina Zouambia , Khadidja Youcef Ettoumi , Mohamed Krea , Nadji Moulai-Mostefa, Arabian Journal of Chemistry, 2014

Publication date: Available online 13 November 2014 Source:Arabian Journal of Chemistry Author(s): Yamina Zouambia , Khadidja Youcef Ettoumi , Mohamed Krea , Nadji Moulai-Mostefa Electromagnetic induction (EMI) and conventional (CV) heating have been employed to extract pectin from ...


Purification and Mode of Action of Antilisterial Bacteriocins Produced by Lactobacillus pentosus SJ65 Isolated from Uttapam Batter

21-11-2014 | Appukuttan Saraniya, Kadirvelu Jeevaratnam, Journal of Food Biochemistry, 2014

Abstract Humans and lactic acid bacteria (LAB) have allied relationships for thousands of years, where LAB has been involved in food preservations as well as in preserving human health against several pathogens. This study aims at partial purification of bacteriocins from Lactobacillus ...


Epithelial Transport of Immunogenic and Toxic Gliadin Peptides In Vitro

21-11-2014 | Christian Zimmermann et al., PLoS ONE, 2014

by Christian Zimmermann, Silvia Rudloff, Günter Lochnit, Sevgi Arampatzi, Wolfgang Maison, Klaus-Peter Zimmer Scope Celiac disease is an autoimmune disorder caused by failure of oral tolerance against gluten in genetically predisposed individuals. The epithelial translocation of gluten-derived ...


Particle Size Distribution of Halogenated Flame Retardants and Implications for Atmospheric Deposition and Transport

21-11-2014 | Krzysztof Okonski; Céline Degrendele; Lisa Melymuk; Linda Landlová; Petr Kukučka; Šimon Vojta; Jiří Kohoutek; Pavel ..., Environmental Science & Technology, 2014

This study investigates the distribution of polybrominated diphenyl ethers (PBDEs), hexabromocyclododecane (HBCD) and a group of novel flame retardants (NFRs) on atmospheric aerosols. Two high volume cascade impactors were used to collect particulate fractions of ambient air over a one year ...


Characterization of Low Molecular Weight Allergens from English Walnut (Juglans regia)

20-11-2014 | Melanie L. Downs; Aida Semic-Jusufagic; Angela Simpson; Joan Bartra; Montserrat Fernandez-Rivas; Neil M. Rigby; Stev ..., Journal of Agricultural and Food Chemistry, 2014

Although English walnut is a commonly allergenic tree nut, walnut allergens have been poorly characterized to date. The objective of this work was to characterize the natural, low molecular weight (LMW) allergens from walnut. A protocol was developed to purify LMW allergens (specifically 2S ...


Optimization of Spray Drying Process in Commercial Hydrolyzed Fish Scale Collagen and Characterization by Scanning Electron Microscope and Fourier Transform Infrared Spectroscopy

19-11-2014 | Laila D. Latip, Wahidu Zzaman, Md. Zainul Abedin, Tajul A. Yang, Journal of Food Processing and Preservation, 2014

Abstract Response surface methodology was applied to optimize the yield of commercial hydrolyzed fish collagen (Cc) using spray drying process. Two factors were investigated including inlet temperature (130–150C) and flow rate (6–10%) with response to yield. The maximum yields (60.93%) were ...


Molecular Dynamics Simulations of Hyperbranched PAMAM Vicsek Fractals

19-11-2014 | Florian Fürstenberg, Andrey A. Gurtovenko, Maxim Dolgushev, Alexander Blumen, Macromolecular Theory and Simulations, 2014

Within the broad class of hyperbranched polymers, highly symmetrical objects (such as dendrimers and Vicsek fractals) are of special theoretical interest. Here we study, using the MARTINI force‐field, polyamidoamine Vicsek fractals (PVF) in silico, focusing on their structure and dynamics in ...


Above, below, and in‐between the two glass transitions of ultrathin free‐standing polystyrene films: Thermal expansion coefficient and physical aging

19-11-2014 | Justin E. Pye, Connie B. Roth, Journal of Polymer Science Part B: Polymer Physics, 2014

ABSTRACT In previous work we observed two simultaneous transitions in high molecular weight (MW) free‐standing polystyrene films that were interpreted as two thickness‐dependent reduced glass transition temperatures (Tgs). The weaker lower transition agreed well with the MW‐dependent Tg(h) ...


Copolymerization and Synthesis of Multiply Binding Histamine Ligands for the Robust Functionalization of Quantum Dots

19-11-2014 | Anand Viswanath; Yi Shen; Alexandra N. Green; Rui Tan; Andrew B. Greytak; Brian C. Benicewicz, Macromolecules, 2014

The polymeric functionalization of quantum dots via ligand exchange is a robust method for the preparation of stable fluorescent particles with high quantum yields. For most biological applications of quantum dots, water solubility is a key requirement; to achieve biocompatibility, polymeric ...
