Journal Highlight: A study of long-term fMRI reproducibility using data-driven analysis methods

Date: Jan 19, 2015

Author: spectroscopyNOW

Long-term fMRI reproducibility has been investigated with a focus on the data analysis methods and the effects of a wavelet-domain Bayesian method and the Gaussian method for smoothing on the long-term reproducibility were assessed.

Perflorooctane sulphonate toxicity: Proteomics study of liver cell damage

Date: Jan 15, 2015

Author: Steve Down

The effects of perfluorooctane sulphonate on human liver cells have been examined by proteomics techniques to help identify biomarkers for monitoring and contamination and expose the hepatotoxicity mechanisms.

Choose greens wisely: AAS reveals calcium availability

Date: Jan 15, 2015

Author: David Bradley

An in vitro study using atomic absorption spectroscopy has investigated the concentrations of calcium found in diverse green vegetables commonly used in Indian cuisine as well as allowing the researchers to comment on the availability for absorption from the diet of the calcium present in these edible plants.

Enzyme structure: Crystallography of ubiquitous protein

Date: Jan 15, 2015

Author: David Bradley

US scientists have used X-ray crystallography to focus on an almost ubiquitous metabolic enzyme, nicotinamide nucleotide transhydrogenase, found in most life forms but with medically relevant links to diseases as disparate as diabetes and cancer.

Epigenetics: Finding the right data signals

Date: Jan 15, 2015

Author:

Epigenetic signals help determine which genes are activated at a given time in a particular cell in the body. Now, researchers in Germany have used a  novel analytical method to enable them to systematically characterize the relevant epigenetic tags and so reveal how the system adapts to the loss of single epigenetic writer and eraser enzymes.

Full of beans: NMR spectroscopy confirms coffee

Date: Jan 15, 2015

Author:

An international team from Colombia and Germany has demonstrated how to use NMR spectroscopy to identify adulteration or contamination of coffee beans based on country of origin, a useful tool in the fight against food fraud in a high-value market.

Journal Highlight: Observation of crack propagation in glass using X-ray phase contrast imaging

Date: Jan 12, 2015

Author: spectroscopyNOW

High-speed X-ray phase contrast imaging synchronized with a Kolsky bar apparatus was utilized to investigate the cracking behavior of three types of glass after impact with a cylindrical projectile.
