The cannabinoid Δ9-tetrahydrocannabinol inhibits RAS-MAPK and PI3K-AKT survival signalling and induces BAD-mediated apoptosis in colorectal cancer cells (2007)
Journal Article

Deregulation of cell survival pathways and resistance to apoptosis are widely accepted to be fundamental aspects of tumorigenesis. As in many tumours, the aberrant growth and survival of colorectal tumour cells is dependent upon a small number of hig...

Hypomethylation and aberrant expression of the glioma pathogenesis-related 1 gene in Wilms tumors (2007)
Journal Article

Wilms tumors (WTs) have a complex etiology, displaying genetic and epigenetic changes, including loss of imprinting (LOI) and tumor suppressor gene silencing. To identify new regions of epigenetic perturbation in WTs, we screened kidney and tumor DNA...

Is hydrophilic interaction chromatography with silica columns a viable alternative to reversed-phase liquid chromatography for the analysis of ionisable compounds? (2007)
Journal Article

The separation of acidic, neutral and particularly basic solutes was investigated using a bare silica column, mostly under hydrophilic interaction chromatography (HILIC) conditions with water concentrations >2.5% and with >70% acetonitrile (ACN). Pro... Read More about Is hydrophilic interaction chromatography with silica columns a viable alternative to reversed-phase liquid chromatography for the analysis of ionisable compounds?.

Voltammetric behaviour of p-nitrophenol and its trace determination in human urine by liquid chromatography with a dual reductive mode electrochemical detection system (2007)
Journal Article

The determination of trace p-nitrophenol (PNP) concentrations in human urine has been successfully achieved by high performance liquid chromatography dual electrode detection (LC-DED) in the reduction-reduction mode. Initial cyclic voltammetric studi...

In vitro biofilm model for studying tongue flora and malodour (2007)
Journal Article

Aims: To develop a perfusion biofilm system to model tongue biofilm microflora and their physiological response to sulfur-containing substrates (S-substrates) in terms of volatile sulfide compound (VSC) production. Methods and Results: Tongue-scrape... Read More about In vitro biofilm model for studying tongue flora and malodour.

Do we expect natural selection to produce rational behaviour? (2007)
Journal Article

We expect that natural selection should result in behavioural rules which perform well; however, animals (including humans) sometimes make bad decisions. Researchers account for these with a variety of explanations; we concentrate on two of them. One... Read More about Do we expect natural selection to produce rational behaviour?.

Paramagnetic particle detection for use with an immunoassay based biosensor (2007)
Journal Article

A biosensor and detection system that can provide measurement of analyte concentration within a test sample in four minutes is presented. The biosensor uses an immunoassay with micrometre-sized paramagnetic particle (PMP) labels for quantification. A...

Use of a bioluminescent Pseudomonas aeruginosa strain within an in vitro microbiological system, as a model of wound infection, to assess the antimicrobial efficacy of wound dressings by monitoring light production (2007)
Journal Article

A bioluminescent Pseudomonas aeruginosa was incorporated into an in vitro static diffusion method to determine whether light output could be used as a measure of wound dressing efficacy. A significant linear correlation was observed between viable co...

Violations of transitivity under fitness maximization (2007)
Journal Article

We present a novel demonstration that violations of transitive choice can result from decision strategies that maximize fitness. Our results depend on how the available options, including options not currently chosen, influence a decision-maker's exp... Read More about Violations of transitivity under fitness maximization.
