An NMR and molecular modelling study on the solution conformation of Heparan Sulphate: new insights into the relationship between structure and function
A deeper insight into the structural biology of HS is key to understanding its nearuniversal functional role as a co-receptor for growth factors and morphogens. Due to the extreme difficulty in preparing homogeneous HS oligosaccharides for structural and functional studies, traditionally, …

Synthetic and analytical investigations related to vegetable oils and fats.
The work presented here has developed along two lines: analysis and synthesis of triacylglycerols. A new application is reported in the use of the infrared detector in HPLC for the detection and preparative and quantitative separation of triacylglycerols of seed fats and oils, acylglycerols from …

Chemical Profiling of Ballistic Materials - Analysis of organic gunshot residue
Gunshot residue (GSR) is a complex chemical mixture that is created during the discharge of a firearm. Its detection and interpretation play a crucial role in the investigation of firearm incidents. Current GSR analysis is limited to inorganic GSR (IGSR), however, the evidential value could be …

Development of Knowledge Within a Chemical-Toxicological Database to Formulate Novel Computational Approaches for Predicting Repeated Dose Toxicity of Cosmetics-Related Compounds
The European Union (EU) Cosmetics Regulation established the ban on animal testing for cosmetics ingredients. This ban does not assume that all cosmetics ingredients are safe, but that the non-testing procedures (in vitro and in silico) have to be applied for their safety assessment. To this end, …

Protein containing porous polymers for biocatalytic applications
Over the last twenty years there has been a great deal of research conducted into the use of enzymes as catalysts for reactions conducted in non-aqueous media. Not only has it been shown that enzymes can function effectively in organic media, but also that the range of reactions that they can …

Detection of human salivary α-Defensins by LC-ESI-MS and evaluation of levels in athletes after physical stress
The aim of this study was to optimise and validate an LC-ESI-MS method to determine the level of individual human neutrophil alpha defensins (HNP1-4) after physical stress. A method for the analysis of individual (HNP1-4) in a saliva matrix by LC-ESI-MS has been established. An Agilent 1200 series …
