Evidence for a population collapse of European eel (Anguilla anguilla) in the Bristol Channel (2012)
Journal Article

A 30-year study of the estuarine population of yellow eel, Anguilla anguilla, abundance in Bridgwater Bay, Somerset, UK, shows that the population number has collapsed. Since 1980, the decline has averaged 15% per year. The abundance of eel in 2009 i... Read More about Evidence for a population collapse of European eel (Anguilla anguilla) in the Bristol Channel.

Breath ammonia analysis: Clinical application and measurement (2011)
Journal Article

This review covers in detail the complexity of human breath, how the body metabolizes ammonia, clinical conditions which are directly related to the regulation of ammonia concentration, and analysis of current techniques that are capable of detecting...

Breath ammonia levels in a normal human population study as determined by photoacoustic laser spectroscopy (2011)
Journal Article

Photoacoustic laser spectroscopy was used as a technique to measure real-time levels of ammonia in exhaled human breath in a small, locally recruited, normal healthy population (n = 30). This yielded an average level of breath ammonia of 265 ppb, ran... Read More about Breath ammonia levels in a normal human population study as determined by photoacoustic laser spectroscopy.

Logical and arithmetic circuits in Belousov-Zhabotinsky encapsulated disks (2011)
Journal Article

Excitation waves on a subexcitable Belousov-Zhabotinsky (BZ) substrate can be manipulated by chemical variations in the substrate and by interactions with other waves. Symbolic assignment and interpretation of wave dynamics can be used to perform log... Read More about Logical and arithmetic circuits in Belousov-Zhabotinsky encapsulated disks.

Evolving spiking networks with variable memristors (2011)
Presentation / Conference Contribution

Towards evolving spiking networks with memristive synapses (2011)
Presentation / Conference Contribution

This paper presents a spiking neuro-evolutionary system which implements memristors as neuromodulatory connections, ie whose weights can vary during a trial. The evolutionary design process exploits parameter self-adaptation and a constructionist app... Read More about Towards evolving spiking networks with memristive synapses.

Electrochemical sensors: From probes to integrated smart systems (2011)
Presentation / Conference Contribution

The emergence of the field of electroanalytical chemistry has transformed measurement science. Early application of electrochemical probes for simple ionic species has given way to more sophisticated measurements involving further chemo-selective and...

Opportunities for sensors in printed electronics (2011)
Presentation / Conference Contribution

Electrochemical sensor strips were one of the first devices to become a global success in what might now be termed the printed electronics industry. Since their creation some 20 years ago, printed sensor strips are used extensively for a range of cli... Read More about Opportunities for sensors in printed electronics.

Quantification of unfractionated heparin in human plasma and whole blood by means of novel fluorogenic anti-FXa assays (2011)
Journal Article

Novel and sensitive plate-based fluorogenic anti-factor Xa (FXa) assays were investigated to quantify unfractionated heparin (UFH) in human plasma and whole blood within the therapeutic ranges of 0-1.6. U/mL and 0-0.8. U/mL, respectively. Two fluorog... Read More about Quantification of unfractionated heparin in human plasma and whole blood by means of novel fluorogenic anti-FXa assays.

The role of oscillatory brain activity in object processing and figure-ground segmentation in human vision (2011)
Journal Article

The perception of an object as a single entity within a visual scene requires that its features are bound together and segregated from the background and/or other objects. Here, we used magnetoencephalography (MEG) to assess the hypothesis that coher...

Determination of catecholamines in urine using hydrophilic interaction chromatography with electrochemical detection (2011)
Journal Article

The determination of catecholamines in urine was investigated using hydrophilic interaction chromatography (HILIC) as an alternative to the commonly used reversed-phase (RP) method. A number of different approaches were explored, including per-aqueou...

Inkjet printable polyaniline-gold dispersions (2011)
Journal Article

Inkjet printable polyaniline-gold (PANI-Au) hybrid dispersions were synthesised using gold salt as oxidant to simultaneously induce chemical oxidative polymerisation of aniline and reduction of HAuCl4 in bulk aqueous solution. By varying the amount o... Read More about Inkjet printable polyaniline-gold dispersions.

The role of the Aedes aegypti Epsilon glutathione transferases in conferring resistance to DDT and pyrethroid insecticides (2011)
Journal Article

The Epsilon glutathione transferase (GST) class in the dengue vector Aedes aegypti consists of eight sequentially arranged genes spanning 53,645 bp on super contig 1.291, which maps to chromosome 2. One Epsilon GST, GSTE2, has previously been implica... Read More about The role of the Aedes aegypti Epsilon glutathione transferases in conferring resistance to DDT and pyrethroid insecticides.

Contributions to reversed-phase column selectivity. II. Cation exchange (2011)
Journal Article

The contribution of cation exchange to solute retention for type-B alkylsilica columns (made from high-purity silica) has been examined in terms of the hydrophobic-subtraction (H-S) model of reversed-phase column selectivity. The relative importance... Read More about Contributions to reversed-phase column selectivity. II. Cation exchange.

Some practical comparisons of the efficiency and overloading behaviour of sub-2μm porous and sub-3μm shell particles in reversed-phase liquid chromatography (2011)
Journal Article

At their optimum flow, sub-3 μm superficially porous or " shell" particles demonstrate similar efficiency to sub-2 μm totally porous particles. The performance of 0.21. cm i.d shell columns is however inferior to those of 0.46. cm i.d., presumably du...

Inter-laboratory study of the in vitro dendritic cell migration assay for identification of contact allergens (2011)
Journal Article

The aim of this study was to investigate the transferability of technology and reproducibility of MUTZ-3 derived Langerhans Cell (MUTZ-LC) migration assay. The protocol was transferred from the NL-lab to two Sens-it-iv project partners (UK-lab, Italy...
