(Elsevier, 2009-02-23)Enrichment techniques have become an important feature in the trace analysis of oestrogen mimicking chemicals in the environment. Recent developments such as accelerated solvent extraction (ASE) have improved extraction ... -
Advanced therapies and the outer limits of DNA regulation: new horizons for patents or a scaffold too far?
(Oxford Academic, 2008-04)This Regulation seeks to regulate existing and future advanced therapy medicinal products intended for the market in Member States, being either prepared industrially or manufactured by a method involving an industrial ... -
Investigations on the efficacy of routinely used phenotypic methods compared to genotypic approaches for the identification of staphylococcal species isolated from companion animals in Irish veterinary hospitals
(BMC, 2013)BACKGROUND: Identification of Staphylococci to species level in veterinary microbiology is important to inform therapeutic intervention and management. We report on the efficacy of three routinely used commercial phenotypic ... -
UPLC® method development and validation for the assay of the photolabile drug nifedipine and its trace level degradation products.
(The Institute of Chemistry of Ireland, 2017-06)Quality assurance regulations require that pharmaceutical drugs are highly pure. This is in order to ensure the safety and efficacy of medicines for patients, two fundamental issues of importance in treatment. The safety ... -
Characterisation of biopharmaceuticals
(The Institute of Chemistry of Ireland, 2016-07)Biopharmaceuticals are drugs which are primarily (glyco)protein in nature, that are produced in living cells using recombinant DNA technology – the combination of genetic material from multiple sources, creating sequences ... -
Analysis of bio-obtainable endocrine disrupting metals in river water and sediment, sewage influent/effluent, sludge, leachate, and concentrated leachate, in the Irish Midlands Shannon catchment.
(Hindawi, 2009-12)The application of an acid digestion and subsequent solid-phase extraction (SPE) procedure were implemented as preliminary treatments prior to quantifying the levels of potentially endocrine disrupting metals (EDMs) in a ... -
Prediction of toxigenic fungal growth in buildings by using a novel modelling system.
(American Society for Microbiology, 1999-11)There is growing concern about the adverse effects of fungal bioaerosols on the occupants of damp dwellings. Based on an extensive analysis of previously published data and on experiments carried out within this ... -
Analytical characterization and pharmacological evaluation of the new psychoactive substance 4-fluoromethylphenidate (4F-MPH) and differentiation between the (±)-threo- and (±)-erythro- diastereomers
(Wiley, 2017-03)Misuse of (±)-threo-methylphenidate (methyl-2-phenyl-2-(piperidin-2-yl)acetate; Ritalin®; MPH) has long been acknowledged, but the appearance of MPH analogs in the form of 'research chemicals' has only emerged in more ... -
