Multi-component medicine made manageable by mass spectrometry

Date: Feb 1, 2017

Author: Ryan De Vooght-Johnson

The Chinese medicine Deng-Zhan-Sheng-Mai, used to treat stroke patients, consists of a mixture of four different herbal extracts, each containing a wide variety of compounds, thus giving a huge headache to analysts. Researchers from Fudan University, Shanghai and China Pharmaceutical University, Nanjing used LC-MS, along with chemometric methods, such as hierarchical cluster analysis, principal component analysis and bivariate correlation analysis, to bring order to the chaos, recommending that nine...

Prickly pear: Statistical chemicals

Date: Jan 15, 2017

Author: David Bradley

Chemical statistics have been used in the analysis of extracts from two common species found on the Mediterranean, the prickly pear and the peacock's tail seaweed; the chemicals show promise in easing symptoms of Alzheimer's and Parkinson's disease.

Biomarkers of breast cancer

Date: Jan 12, 2017

Author: Ryan De Vooght-Johnson

The success of cancer treatment hinges on the stage at which the disease is detected, making biomarkers that flag up early signs of the disease an important goal for cancer research. Now a group of scientists from the Czech Republic has found a new set of biomarkers for breast cancer based on the levels of lipids expressed by cancer cells.

Iranian chemists identify Russian chemical warfare agents

Date: Jan 1, 2017

Author: Ryan De Vooght-Johnson

All chemical weapons were banned by the Chemical Weapons Convention, but concerns about the possible use of these substances still persist. Writing in Rapid Communications in Mass Spectrometry, Iranian researchers disclose GC/MS and LC-MS/MS methods for detecting a number of the obscure ‘Novichok’ chemical warfare agents.

Fat work: Analysis and PLS

Date: Dec 15, 2016

Author: David Bradley

Elevated circulating concentrations of free fatty acids (FFAs) is generally considered to be a universal metabolic signature of excessive adipocyte lipolysis. Accurately screening and assessing the problem is now possible thanks to the development of a novel combination of UHPLC-Orbitrap and partial least squares (PLS).

Futuristic MS methods found feasible for forensics, pharma and food

Date: Dec 1, 2016

Author: Ryan De Vooght-Johnson

Curiosity killed the cat—allegedly—but also allowed Sapiens to flourish. At the heart of humankind’s endless curiosity lies a labyrinth of data, verging on too complex and too vast for humankind to process. In response, scientists have handed their MS/MS data to silicon, to great success.
