The differentiation of biodegradable and non-biodegradable dissolved organic matter in wastewaters using fluorescence spectroscopy (2002)
Journal Article

The chemical and biochemical oxygen demand values of a number of synthetic and wastewater samples were determined using fluorescence spectroscopy. Treated and untreated sewage samples were obtained from a local sewage treatment works while synthetic...

Voltammetric behaviour and trace determination of copper at a mercury-free screen-printed carbon electrode (2002)
Journal Article

Screen-printed carbon electrodes (SPCEs), without chemical modification, have been investigated as disposable sensors for the measurement of trace levels of Cu2+. Cyclic voltammetry was employed to elucidate the electrochemical behaviour of Cu2+ at t...

The synthesis of 3-octadecyl- and 3-docosylpyrrole, their polymerisation and incorporation into novel composite gas sensitive resistors (2002)
Journal Article

3-Octadecylpyrrole and the novel 3-docosylpyrrole were synthesised in high yields. These monomers were polymerised with various oxidising agents to produce a range of 3-octadecylpolypyrroles and 3-docosylpolypyrroles with different counter-ions. Thes...

Systematic review of whether nurse practitioners working in primary care can provide equivalent care to doctors (2002)
Journal Article

Objective. To determine whether nurse practitioners can provide care at first point of contact equivalent to doctors in a primary care setting. Design. Systematic review of randomised controlled trials and prospective observational studies. Data sour...

The fabrication and characterisation of a highly sensitive polypyrrole sensor and its electrical responses to amines of differing basicity at high humidities (2002)
Journal Article

Ammonia is a common feedstock for many chemical processes involving nitrogen compounds. It is a poisonous, colourless gas with a pungent smell and a fairly low odour threshold of approximately 5 ppm. The recommended threshold limit value for human ex...

Dynamic imaging of endoplasmic reticulum Ca2+ concentration in insulin-secreting MIN6 cells using recombinant targeted cameleons: Roles of sarco(endo)plasmic reticulum Ca2+-ATPase (SERCA)-2 and ryanodine receptors (2002)
Journal Article

The endoplasmic reticulum (ER) plays a pivotal role in the regulation of cytosolic Ca2+ concentrations ([Ca2+]cyt) and hence in insulin secretion from pancreatic β-cells. However, the molecular mechanisms involved in both the uptake and release of Ca...

Expression of lux genes in a clinical isolate of Streptococcus pneumoniae: Using bioluminescence to monitor gemifloxacin activity (2002)
Journal Article

A clinical isolate of Streptococcus pneumoniae was transformed with a plasmid containing the lux operon of Photorhabdus luminescens that had been modified to function in gram-positive bacteria. Cells containing this plasmid produced light stably and...

Identification of a peroxide-sensitive redox switch at the CXXC motif in the human mitochondrial branched chain aminotransferase (2002)
Journal Article

The human mitochondrial branched chain aminotransferase isoenzyme (hBCATm) must be stored in a reducing environment to remain active. Oxidation or labeling of hBCATm with sulfhydryl reagents results in enzyme inhibition. In this study, we investigate...

Concentrations of Cd, Zn and Cu in sediments and brown shrimp (Crangon crangon L.) from the Severn Estuary and Bristol Channel, UK (2002)
Presentation / Conference Contribution

Cd, Zn and Cu levels were determined in sediments and Crangon crangon from 9 sites in the Severn Estuary/Bristol Channel during winter 1999. Metal levels in both shrimp and sediments varied significantly between sites and were related to proximity of...

The relationship between adipose tissue skatole levels, rates of hepatic microsomal skatole metabolism and hepatic cytochrome P450IIE1 expression in two breeds of pig (2002)
Journal Article

The relationships between the level of skatole in backfat, the rate of skatole metabolism in isolated liver microsomes, hepatic cytochrome P450IIE1 content and mRNA levels were investigated in Large White ✕ Landrace (LW) and the Meishan ✕ Landrace...

Cytochrome P450IIE1 (CYP2E1) is induced by skatole and this induction is blocked by androstenone in isolated pig hepatocytes (2002)
Journal Article

Skatole, a derivative of tryptophan, is produced in the hind-gut of pigs and is metabolised via hepatic cytochrome P4502E1 (CYP2E1). Excessive accumulation of skatole together with androstenone, a metabolite of testosterone, in adipose tissue in some...
