A Proteomic Ruler That Measures Up


via Accelerating Science » Amanda Maxwell http://ift.tt/1SOxIV1

According to Wiśniewski et al. (2014), using the mass spectrometry (MS) signal generated by histones is a reliable and easily implemented first step in quantitating proteins.1  Furthermore, using the “proteomic ruler” tool developed by the authors, researchers can cut out several steps that potentially introduce error in MS-based proteomic quantitative analysis. Since its introduction into Read the rest of this article

Measuring Primary Aromatic Amine Migration into Foods by Targeted LC-HRMS


via Accelerating Science » Amanda Maxwell http://ift.tt/1PTODAa

Sanchis et al. (2015) present a sensitive and efficient method for measuring primary aromatic amine (PAA) contamination in foodstuffs using liquid chromatography coupled with high resolution mass spectrometry (LC-HRMS)1. The method the researchers propose benefits food safety monitoring by providing both targeted measurement of PAAs but also post-target screening for other common migratory contaminants such Read the rest of this article

Plant Antimicrobials and the Food Industry: Part 3 – Phytochemicals


via Accelerating Science » Amanda Maxwell http://ift.tt/1QE17PG

Phytochemicals are components within a plant that often impart taste or flavor. Classified as non-nutritive, these factors can also be antimicrobial—a property that has been exploited throughout history. Many cultures use herbs and spices in both cooking and medicine, as much for the pleasant sensations they impart as for their antimicrobial actions against foodborne pathogens, Read the rest of this article

The E. coli Acetylome: Form and Function


via Accelerating Science » Amanda Maxwell http://ift.tt/1SmSMn2

Castaño-Cerezo et al. (2014) conducted a proteomic evaluation of the Escherichia coli acetylome under four different growth conditions.1 As a post-translational modification (PTM), acetylation of lysine residues contributes to regulation of cellular activity with activation or inactivation of key proteins such as enzymes and other signaling molecules. By modifying nutrition and growth conditions in vitro, the Read the rest of this article

A little time for this


Time can be in short supply but if I add up the time spent waiting around, then it seems abundant.
However, time spent waiting can be wasted time since it's difficult to put it toward working on a project. When you're not sure how much time there is, there's little point embarking on something big.
And this is where digital sketching comes in. Have tablet, have stylus - will sketch!

The Endometrial Proteome and Unexplained Infertility


via Accelerating Science » Amanda Maxwell http://ift.tt/1RQGPp7

In 25 to 35% of cases of primary infertility, doctors cannot reach a diagnosis that fully explains why a patient is infertile. This means that many women never learn why they cannot conceive and, as a result, fail to receive effective treatment. Manohar et al. (2015) attempt to set fertility research on the right track Read the rest of this article
