Voltammetric, chromatographic and mass spectral elucidation of the redox reactions of 1-hydroxypyrene occurring at a screen-printed carbon electrode (2004)
Journal Article

The electrochemical oxidation of 1-hydroxypyrene (1-OHP) has been studied at a screen-printed carbon electrode (SPCE), by cyclic voltammetry and bulk electrolysis. Cyclic voltammograms exhibited two quasi-reversible pairs of peaks (designated 1a′/1c...

Use of External Magnetic Fields to Reduce Reaction Times in an Immunoassay Using Micrometer-Sized Paramagnetic Particles as Labels (Magnetoimmunoassay) (2004)
Journal Article

The paper presents a rapid immunoassay system capable of quantifying analyte in complex biological and environmental media. Antibody-coated micrometer-sized paramagnetic particles are used as labels in an assay in which they bind quantitatively with...

Voronoi diagrams generated by regressing edges of precipitation fronts (2004)
Journal Article

The Voronoi diagram generated by regression edges of precipitation fronts was analyzed. In the reaction-diffusion system, one of the reagents penetrates into a gel by diffusion and forms a precipitate with the other reagent homogenized in the gel. It...

Development of an siRNA-based method for repressing specific genes in renal organ culture and its use to show that the Wt1 tumour suppressor is required for nephron differentiation (2004)
Journal Article

Wt1 is a tumour suppressor gene, mutation of which is a cause of Wilms' tumour, a childhood renal nephroblastoma. Wt1 is expressed in a rich pattern during renal development suggesting that it acts at three stages: determination of the kidney area, t...

New equations for redox and nano-signal transduction (2004)
Journal Article

Cells maintain redox potentials (Eh) in intracellular compartments, sometimes referred to as redox environments. These potentials are often very reducing, for example in the cytoplasm, but throughout the cell different potentials are maintained, comm...

Convection induced by the selective absorption of radiation for the Brinkman model (2004)
Journal Article

Convection induced by the selective absorption of radiation in a porous medium is studied analytically and numerically using the Brinkman model. Both linear instability analysis and nonlinear stability analysis are employed. The thresholds show excel...

The formation of voronoi diagrams in chemical and physical systems: Experimental findings and theoretical models (2004)
Journal Article

The work discusses the formation of Voronoi diagrams in spatially extended nonlinear systems taking experimental and theoretical results into account. Concerning experimental systems a number of chemical systems used previously as prototype chemical...

A novel method for rapidly diagnosing the causes of diarrhoea (2004)
Journal Article

Background: The microbiological diagnosis of infectious diarrhoea may take several days using conventional techniques. In order to determine whether flatus can be used to make a rapid diagnosis, the volatile organic compounds associated with diarrhoe...

Identification by gas chromatography-mass spectrometry of the volatile organic compounds emitted from the wood-rotting fungi Serpula lacrymans and Coniophora puteana, and from Pinus sylvestris timber (2004)
Journal Article

Volatile organic compounds (VOCs) emitted by two wood-rotting basidiomycete fungi, Serpula lacrymans (dry rot fungus) and Coniophora puteana (cellar fungus), and the timber of Pinus sylvestris (Scots pine), were identified. Several volatile collectio...

Hydrogen peroxide is a common signal for darkness and ABA-induced stomatal closure in Pisum sativum L. (2004)
Journal Article

The requirement for hydrogen peroxide (H2O2) generation and action during stomatal closure induced by darkness and abscisic acid (ABA) was investigated in pea (Pisum sativum L.). Stomatal closure induced by darkness or ABA was inhibited by the H2O2-s... Read More about Hydrogen peroxide is a common signal for darkness and ABA-induced stomatal closure in Pisum sativum L..
