Journal Highlight: Tracking and quantification of magnetically labeled stem cells using magnetic resonance imaging

Date: Jul 25, 2016

Author: spectroscopyNOW

Recent advances in tracking and quantification of superparamagnetic iron oxide nanoparticle-labeled stem cells with magnetic resonance imaging, a noninvasive approach that can longitudinally monitor transplanted cells, are discussed.

Journal Highlight: Proteome rearrangements after auditory learning: high-resolution profiling of synapse-enriched protein fractions from mouse brain

Date: Jul 25, 2016

Author: spectroscopyNOW

A label-free quantification approach was utilized to identify regulated synaptic junctional proteins and phosphoproteins in the auditory cortex, frontal cortex, hippocampus, and striatum of mice 24 h after an auditory learning experiment.

Fingermark proteomics: Blood proteins by mass spec imaging

Date: Jul 19, 2016

Author: Steve Down

The proteins in blood that are present on a human fingermark can be identified by a mass spectrometric imaging technique that preserves the integrity of the ridge patterns so that the biometric information can also be extracted.

Indoor air pollutants: Links to respiratory problems in French houses

Date: Jul 19, 2016

Author: Steve Down

Volatile and semi-volatile compounds that have been implicated in respiratory problems have been measured in French homes where children live to assess the risks of exposure.

Journal Highlight: Using the robust principal component analysis algorithm to remove RF spike artifacts from MR images

Date: Jul 18, 2016

Author: spectroscopyNOW

The Robust Principal Component Analysis algorithm has been used to remove the brief bursts of RF noise during magnetic resonance data acquisition (k-space spikes) that cause disruptive image artifacts, without affecting the underlying signals.

Journal Highlight: Portable and Raman imaging usefulness to detect decaying on mortars from Punta Begoña Galleries

Date: Jul 15, 2016

Author: spectroscopyNOW

An innovative sensor conjugating molecularly imprinted polymers and surface enhanced Raman spectroscopic-active substrate (MIPs-SERS) for the simultaneous extraction and determination of melamine from tap water and milk gave low LOD and LOQ.

Pig data: Odour analysis

Date: Jul 15, 2016

Author: David Bradley

Chemical informatics can be used to let you know just how smelly is that pig farm, without having to muddy your boots. Usually, it takes a nose to know a smell, but processing analytical data can now be used to define odour levels, according to researchers in Denmark.

Naked eye genetics: NMR assists development

Date: Jul 15, 2016

Author: David Bradley

Nuclear magnetic resonance (NMR) spectroscopy has been used to validate and verify the development of a new naked-eye nucleic acid detection and diagnostics technology developed by researchers in Germany.

Butts are no joke: FAAS, the evidence

Date: Jul 15, 2016

Author: David Bradley

Graphite furnace atomic absorption spectrophotometry (FAAS) reveals that toxic metals from cigarette butts could be an important source of pollution thanks to the millions that are discarded by smokers and end up on shorelines and in the oceans.

Quick change toxin: By cryo-electron microscopy

Date: Jul 15, 2016

Author: David Bradley

International scientists have turned to cryo-electron microscopy rather than X-ray crystallography or nuclear magnetic resonance (NMR) spectroscopy to help them unravel the structure of a deadly bacterial toxin that rips holes in body cells.
