Journal Article
Screen-printed carbon electrodes (SPCEs) have been modified with two different calixarenes; a novel thiolated calixarene (5,11,17,23,tetra-tert-butyl-25,26,27,28-tetrakis(2-mercaptoethoxy)- calix[4]arene), and the commercially available 25,26,27,28-t...

The structure of human mitochondrial branched-chain aminotransferase (2001)
Journal Article
X-ray crystal structures of three forms of human mitochondrial branched-chain aminotransferase were solved by molecular-replacement methods. In two of the forms the enzyme is in its active form, with the pyridoxal 5′-phosphate (PLP) cofactor covalent... Read More about The structure of human mitochondrial branched-chain aminotransferase.
Influx and accumulation of Cs+ by the akt1 mutant of Arabidopsis thaliana (L.) Heynh. lacking a dominant K+ transport system (2001)
Journal Article
An extensive literature reports that Cs+, an environmental contaminant, enters plant cells through K+ transport systems. Several recently identified plant K+ transport systems are permeable to Cs+. Permeation models indicate that most Cs+ uptake into... Read More about Influx and accumulation of Cs+ by the akt1 mutant of Arabidopsis thaliana (L.) Heynh. lacking a dominant K+ transport system.
Fish fauna of the Severn Estuary. Are there long-term changes in abundance and species composition and are the recruitment patterns of the main marine species correlated? (2001)
Journal Article
Fish were collected from the intake screens of the Oldbury Power Station in the Severn Estuary in each week between early July 1972 and late June 1977 and at least twice monthly between early January 1996 and late June 1999. The annual catches, after... Read More about Fish fauna of the Severn Estuary. Are there long-term changes in abundance and species composition and are the recruitment patterns of the main marine species correlated?.
Voltammetric studies of lead at a 1-(2-pyridylazo)-2-naphthol modified screen-printed carbon electrode and its trace determination in water by stripping voltammetry (2001)
Journal Article
A method for the trace determination of Pb2+, using a disposable 1-(2-pyridylazo)-2-naphthol (PAN) drop-coated modified screen-printed carbon electrode (PAN-SPCE), has been developed. Lead ions (Pb2+) are accumulated from ammonia buffer, on the PAN-S...

The CD34+CD38neg population is significantly increased in haemopoietic cell expansion cultures in serum-free compared to serum-replete conditions: Dissociation of phenotype and function (2001)
Journal Article
Expansion of haemopoietic stem cells is proposed to combat graft failure in adult recipients following cord blood (CB) transplantation. Cultures are traditionally performed in medium containing FCS, but to transfer expansion to the clinic, 'good manu...

Heavy metal contamination of brown seaweed and sediments from the UK coastline between the Wear River and the Tees River (2001)
Journal Article
The concentration of Fe, Mn, Zn, Cu, Pb, Ni, Cr, Cd, and Ag were determined in the brown alga Fucus vesiculosus and intertidal surface sediments from coastal locations of northeast England. Levels of heavy metals similar to those of polluted areas of...

Neuronal organization of the melanin-concentrating hormone system in primitive actinopterygians: Evolutionary changes leading to teleosts (2002)
Journal Article
Hypothalamic melanin-concentrating hormone (MCH) neurones occur in all vertebrates and have an apparent neuromodulatory role. In teleost fish, however, MCH is used also as a neurohypophysial hormone, controlling skin color, and as a hypophysiotrophic...

Ammonia vapour in the oral cavity as a diagnostic marker for infection with Helicobacter pylori: Preliminary 'proof of principle' pharmacological investigations (2001)
Journal Article
Most current non-invasive tests for Helicobacter pylori depend on the conversion of labelled (13C or 14C) urea to labelled carbon dioxide (13CO2 or 14CO2) and ammonium (NH4+) by the enzyme urease, with the labelled CO2 detected in exhaled air. Despit... Read More about Ammonia vapour in the oral cavity as a diagnostic marker for infection with Helicobacter pylori: Preliminary 'proof of principle' pharmacological investigations.
Identifying bacteria in human urine: Current practice and the potential for rapid, near-patient diagnosis by sensing volatile organic compounds (2001)
Journal Article
Urinary tract infection (UTI) represents a significant burden for the National Health Service. Extensive research has been directed towards rapid detection of UTI in the last thirty years. A wide range of microbiological and chemical techniques are n...
