When closure gels: Wound healing

Date: Dec 15, 2013

Author: David Bradley

Effective wound closure is vital to avoid significant blood loss following injury and to reduce the risk of infection. Researchers in the US have developed a novel gel that can seal wounds rapidly but be dissolved subsequently to allow the wound to be opened gently if surgery is necessary. Analytical assessment of the associated rheological data demonstrate efficacy.

Social scent networking: Hyena analytics

Date: Nov 15, 2013

Author: David Bradley

US researchers have used statistical methods to unravel the detailed scent posts left by hyenas and demonstrated that at least in part, the markers are a product of more than one species.

Journal Highlight: Near-IR spectroscopy and partial least squares-class modeling for metabolomics fingerprinting discrimination of intervention breakfasts ingested by obese individuals

Date: Oct 14, 2013

Author: spectroscopyNOW

Near-IR spectroscopy has been used in nutritional metabolomics to assess the intake of intervention breakfasts prepared with deep-fried vegetable oils and the resulting urinary patterns were analysed by partial least squares-class modelling.

Extracting the urine: Metabolic profile

Date: Sep 15, 2013

Author: David Bradley

A sophisticated research project at the University of Alberta, Canada, brings together nuclear magnetic resonance spectroscopic data, mass spectrometry and liquid chromatography to identify the 3000 or so chemical metabolites that can be present in a sample human urine. The work is the culmination of more than seven years effort and involved a team comprising almost twenty individual scientists. The researchers anticipate that their detailed chemical profile of urine will have considerable implications for...

Journal Highlight: Phytochemical fingerprints of copaiba oils (Copaifera multijuga Hayne) determined by multivariate analysis

Date: Aug 19, 2013

Author: spectroscopyNOW

Oil samples of Copaifera multijuga Hayne species were characterized by GC-FID and GC/MS and the chromatographic data were processed using hierarchical cluster analysis and principal component analysis to recognize patterns for the chemical composition.
