Mucosal immunity in healthy adults after parenteral vaccination with outer-membrane vesicles from Neisseria meningitidis serogroup B (2008)
Journal Article

Background. Nasopharyngeal carriage of meningococcus or related species leads to protective immunity in adolescence or early adulthood. This natural immunity is associated with mucosal and systemic T cell memory. Whether parenteral Neisseria meningit...

Cats about town: Is predation by free-ranging pet cats Felis catus likely to affect urban bird populations? (2008)
Journal Article

Even though they are fed daily by their owners, free-ranging pet cats Felis catus may kill wild birds and, given their high densities (typically > 200 cats/km2), it has been postulated that cat predation could be a significant negative factor affecti...

Toothpaste detergents: A potential source of oral soft tissue damage? (2008)
Journal Article

OBJECTIVES: Toothpastes are thought to be of benefit to cleaning teeth but may also have the potential for soft tissue damage at least on the cellular level by inclusion of detergents in their formulation. The aim of this study was to observe the in... Read More about Toothpaste detergents: A potential source of oral soft tissue damage?.

On logical gates in precipitating medium: Cellular automaton model (2008)
Journal Article

We study a two-dimensional semi-totalistic binary cell-state cellular automaton, which imitates a reversible precipitation in an abstract chemical medium. The systems exhibits a non-trivial growth and nucleation. We demonstrate how basic computationa... Read More about On logical gates in precipitating medium: Cellular automaton model.

Acute impact of agriculture on high-affinity methanotrophic bacterial populations (2008)
Journal Article

Exposure of mineral soils to atmospherically relevant concentrations of 13CH4 (2 ppmv) followed by 13C-phospholipid fatty acid stable isotope probing allows assessment of the high-affinity methanotrophic bacterial sink in hitherto unattainable detail...

The histidine kinase AHK5 integrates endogenous and environmental signals in Arabidopsis guard cells (2008)
Journal Article

Background: Stomatal guard cells monitor and respond to environmental and endogenous signals such that the stomatal aperture is continually optimised for water use efficiency. A key signalling molecule produced in guard cells in response to plant hor... Read More about The histidine kinase AHK5 integrates endogenous and environmental signals in Arabidopsis guard cells.

Development of an anodic stripping voltammetric assay, using a disposable mercury-free screen-printed carbon electrode, for the determination of zinc in human sweat (2008)
Journal Article

This paper reports on the development of a novel electrochemical assay for Zn2+ in human sweat, which involves the use of disposable screen-printed carbon electrodes (SPCEs). Initially, SPCEs were used in conjunction with cyclic voltammetry to study...

Evaluation of the properties of a superficially porous silica stationary phase in hydrophilic interaction chromatography (2008)
Journal Article

The sample capacity, column efficiency (and its variation with flow) of a superficially porous unbonded silica phase (Halo) was investigated using hydrophilic interaction chromatography (HILIC), particularly for separation of basic compounds. Sample... Read More about Evaluation of the properties of a superficially porous silica stationary phase in hydrophilic interaction chromatography.

Transmission of cocoa swollen shoot virus by seeds (2008)
Journal Article

A study was undertaken to determine whether cocoa swollen shoot virus is transmitted by seeds, to improve the robustness of quarantine procedures for international exchange and long term conservation of cocoa germplasm. PCR/capillary electrophoresis,... Read More about Transmission of cocoa swollen shoot virus by seeds.

Identification of Campylobacter infection in chickens from volatile faecal emissions (2008)
Journal Article

Volatile organic compounds from chicken faeces were investigated as biomarkers for Campylobacter infection. Campylobacter are major poultry-borne zoonotic pathogens, colonizing the avian intestinal tract. Chicken faeces are the principal source of co...

Estimation of the extent of the water-rich layer associated with the silica surface in hydrophilic interaction chromatography (2008)
Journal Article

The possible presence of a mobile phase layer rich in water on the surface of silica columns used under conditions typical in hydrophilic interaction chromatography was investigated by the injection of a small hydrophobic solute (benzene) using aceto...

Stable isotope ratio mass spectrometry and physical comparison for the forensic examination of grip-seal plastic bags (2008)
Journal Article

Plastic bags are frequently used to package drugs, explosives and other contraband. There exists, therefore, a requirement in forensic casework to compare bags found at different locations. This is currently achieved almost exclusively by the use of... Read More about Stable isotope ratio mass spectrometry and physical comparison for the forensic examination of grip-seal plastic bags.

Regulatory control of human cytosolic branched-chain aminotransferase by oxidation and S-glutathionylation and its interactions with redox sensitive neuronal proteins (2008)
Journal Article

Redox regulation of proteins through oxidation and S-thiolation are important regulatory processes, acting in both a protective and adaptive role in the cell. In the current study, we investigated the sensitivity of the neuronal human cytosolic branc...

Apoptotic cells induce dendritic cell-mediated suppression via interferon-γ-induced IDO (2008)
Journal Article

Dendritic cells (DC) are sensitive to their local environment and are affected by proximal cell death. This study investigated the modulatory effect of cell death on DC function. Monocyte-derived DC exposed to apoptotic Jurkat or primary T cells fail... Read More about Apoptotic cells induce dendritic cell-mediated suppression via interferon-γ-induced IDO.

Poiseuille flow in a fluid overlying a porous medium (2008)
Journal Article

This paper numerically investigates the instability of Poiseuille flow in a fluid overlying a porous medium saturated with the same fluid. A three-layer configuration is adopted. Namely, a Newtonian fluid overlying a Brinkman porous transition layer,... Read More about Poiseuille flow in a fluid overlying a porous medium.

Effect of testosterone, estrone sulphate and androstenone on 3β-hydroxysteroid dehydrogenase protein expression in primary cultured hepatocytes (2008)
Journal Article

Androstenone (5α-androst-16-en-3-one) is a steroid pheromone, excessive accumulation of which in pig adipose tissue contributes to the phenomenon of "boar taint". The incidence of boar taint increases with age and weight of entire male pigs. One of t...
