Characterisation of high molecular weight hop proanthocyanidins using Analytical Ultracentrifugation Gadon, Arthur; Linforth, Robert; Harding, Stephen Ernest; Cook, David (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)We report the novel application of Analytical Ultracentrifugation (AUCF) to characterise the polymeric proanthocyanidin fraction of hops. Extraction of hop samples with 70% acetone (aq) followed by a C-18 Solid Phase ...

Cutajar, Michelle; Stockman, Robert A.; Braovac, Susan-Diana; Steindal, Calin Constantin; Zisi, Angeliki; Harding, Stephen Ernest (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Butvar B-98 and PDMS-OH both have a demonstrable ability as consolidants for archaeological wood. This makes them both potential treatment options for the Oseberg collection, which is one of the most important archaeological ...

Wakefield, Jennifer M.K.; Gillis, Richard B.; Adams, Gary G.; McQueen, Caitlin; Harding, Stephen Ernest (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)The heterogeneity and molecular weight of a chitosan of low molecular weight (molar mass) and low degree of acetylation (0.1) for potential use as a consolidant for decayed archaeological wood were examined by sedimentation ...

Harding, Stephen Ernest; Channell, Guy; Phillips-Jones, Mary K (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)We recall the experimental approaches involved in the discovery of hydrogen bonds in deoxyribonucleic acid (DNA) made 70 years ago by a team of scientists at University College Nottingham led by J.M. Gulland, and in relation ...

Dinu, Vlad; Gadon, Arthur; Hurst, Katherine; Lim, Mui; Ayed, Charfeddine; Gillis, Richard B.; Adams, Gary G.; Harding, Stephen Ernest; Fisk, Ian D (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)While a good mucoadhesive biopolymer must adhere to a mucus membrane, it must also have a good unloading ability. Here, we demonstrate that the biopolymer pullulan is partially digested by human salivary α-amylase, thus ...

Lucejko, Jeannette Jacqueline; de Lamotte, Anne; Andriulo, Fabrizio; Kutzke, Hartmut; Harding, Stephen Ernest; Phillips-Jones, Mary K; Modugno, Francesca; Slaghek, Ted M.; Gosselink, Richard J.A.; Braovac, Susan (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)This work is part of a larger study, which aims to use soda lignin from straw as the starting point for a non-aqueous consolidant for highly degraded archaeological wood from the Oseberg collection. This wood was treated ...

McHale, Emily; Steindal, Calin Constantin; Kutzke, Hartmut; Benneche, Tore; Harding, Stephen Ernest (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Waterlogged archaeological wood is often in need of consolidation prior to drying to prevent shrinkage and cracking of the object. There is a need for new greener materials (than for example polyethylene glycol) and methods ...

Dinu, Vlad; Yabukov, Gleb E.; Lim, Mui; Hurst, Katherine; Adams, Gary G.; Harding, Stephen E.; Harding, Stephen Ernest; Fisk, Ian D (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)To reduce animal testing, there is a need to develop novel in-vitro models for evaluating the retention of bioactive compounds in food and pharmaceutical products. Here, a mucus-mimetic platform was developed through a ...

Channell, Guy; Dinu, Vlad; Adams, Gary G.; Harding, Stephen Ernest (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)In establishing the sources of data variability within sedimentation velocity analysis in the analytical ultracentrifuge and their relative importance, recent studies have demonstrated that alignment of the sample cells ...

Dinu, Vlad; Gillis, Richard B; MacCalman, Thomas; Lim, Mui; Adams, Gary G.; Harding, Stephen Ernest; Fisk, Ian D (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Submaxillary mucin is a major component that defines the makeup and functionality of saliva. Understanding its structure and function during food intake is key to designing appropriate strategies for enhancing the delivery ...
-
Harding, Stephen Ernest (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)The analytical ultracentrifuge (AUC) invented by T. Svedberg has now become an extremely versatile and diverse tool in Biochemistry and Polymer Science for the characterisation of the sizes, shapes and interactions of ...
