Decolorization of dyes with different molecular properties using free and immobilized laccases from Trametes versicolor
Publication date: December 2015 Source:Journal of Molecular Liquids, Volume 212 Author(s): Luis A. Ramírez-Montoya, Virginia Hernández-Montoya, Miguel A. Montes-Morán, Juan Jáuregui-Rincón, Francisco J. Cervantes Laccases from Trametes versicolor have been used for the decolorization of acid and reactive dye solutions. The dyes considered were the acid orange 7 (AO7), acid blue 74 (AB74), reactive red 2 (RR2) and reactive black 5 (RB5). The decolorization of dye solutions was performed in batch systems under constant agitation at 30°C, using both free laccases and laccases immobilized on a mesoporous ca...

Discovery of highly conserved unique peanut and tree nut peptides by LC–MS/MS for multi-allergen detection
Publication date: 1 March 2016 Source:Food Chemistry, Volume 194 Author(s): Jennifer Sealey-Voyksner, Jerry Zweigenbaum, Robert Voyksner Proteins unique to peanuts and various tree nuts have been extracted, subjected to trypsin digestion and analysis by liquid chromatography/quadrupole time-of-flight mass spectrometry, in order to find highly conserved peptides that can be used as markers to detect peanuts and tree nuts in food. The marker peptide sequences chosen were those found to be present in both native (unroasted) and thermally processed (roasted) forms of peanuts and tree nuts. Each peptide was selected b...

Tree Nut consumption is associated with better adiposity measures and cardiovascular and metabolic syndrome health risk factors in U.S. Adults: NHANES 2005–2010
IntroductionPrevious research has shown inconsistencies in the association of tree nut consumption with risk factors for cardiovascular disease (CVD) and metabolic syndrome (MetS).ObjectiveTo determine the association of tree nut consumption with risk factors for CVD and for MetS in adults.
Methods:
NHANES 2005–2010 data were used to examine the associations of tree nut consumption with health risks in adults 19+ years (n = 14,386; 51 % males). Tree nuts were: almonds, Brazil nuts, cashews, filberts [hazelnuts], macadamias, pecans, pine nuts, pistachios, and walnuts. Group definitions were non-consumers 25/ (Sourc...

The effect of tree nut, peanut, and soy nut consumption on blood pressure: a systematic review and meta-analysis of randomized controlled clinical trials [Nutritional status, dietary intake, and body composition]
Conclusions: Total nut consumption lowered SBP in participants without type 2 diabetes. Pistachios seemed to have the strongest effect on reducing SBP and DBP. Mixed nuts also reduced DBP. (Source: American Journal of Clinical Nutrition)

NMRFAM-SPARKY: enhanced software for biomolecular NMR spectroscopy
Summary: SPARKY (Goddard and Kneller, SPARKY 3) remains the most popular software program for NMR data analysis, despite the fact that development of the package by its originators ceased in 2001. We have taken over the development of this package and describe NMRFAM-SPARKY, which implements new functions reflecting advances in the biomolecular NMR field. NMRFAM-SPARKY has been repackaged with current versions of Python and Tcl/Tk, which support new tools for NMR peak simulation and graphical assignment determination. These tools, along with chemical shift predictions from the PACSY database, greatly accelerate protein sid...

Development of SSR Markers in Hickory (Carya cathayensis Sarg.) and Their Transferability to Other Species of Carya.
Authors: Li J, Zeng Y, Shen D, Xia G, Huang Y, Huang Y, Chang J, Huang J, Wang Z
Abstract
Hickory (Carya cathayensis Sarg.), an important nut-producing species in Southeastern China, has high economic value, but so far there has been no cultivar bred under species although it is mostly propagated by seeding and some elite individuals have been found. It has been found recently that this species has a certain rate of apomixis and poor knowledge of its genetic background has influenced development of a feasible breeding strategy. Here in this paper we first release SSR (Simple sequence repeat) markers develo...

Phytosterol content and Fatty Acid pattern of ten different nut types.
Authors: Kornsteiner-Krenn M, Wagner KH, Elmadfa I
Abstract
Ten different nut kinds (almonds, Brazil nuts, cashews, hazelnuts, macadamias, peanuts, pecans, pine nuts, pistachios, and walnuts) were evaluated for their total oil and phytosterol content as well as their fatty acid composition. The total oil content was the predominant component; mean values oscillated between 45.2 % (cashews) and 74.7 % (macadamias). Mean total phytosterol content ranged from 71.7 mg (Brazil nuts) to 271.9 mg (pistachios) per 100 g oil. ß-sitosterol was the major sterol (mean >71.7 mg/100 g oil) followed by minor contents...

Exposures of aquatic organisms to the organophosphorus insecticide, chlorpyrifos resulting from use in the United States.
Authors: Williams WM, Giddings JM, Purdy J, Solomon KR, Giesy JP
Abstract
Concentrations of CPY in surface waters are an integral determinant of risk to aquatic organisms. CPY has been measured in surface waters of the U.S. in several environmental monitoring programs and these data were evaluated to characterize concentrations, in relation to major areas of use and changes to the label since 2001, particularly the removal of domestic uses. Frequencies of detection and 95th centile concentrations of CPY decreased more than fivefold between 1992 and 2010. Detections in 1992-2001 ranged from 10.2 to 53%, whi...
