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 ... -
The synthesis and characterization of the ‘research chemical’ N-(1- amino-3-methyl-1-oxobutan-2-yl)-1-(cyclohexylmethyl)-3-(4-fluorophenyl) -1H-pyrazole-5-carboxamide (3,5-AB-CHMFUPPYCA) and differentiation from its 5,3-regioisomer.
(Wiley, 2016-09)This study presents the identification of N-(1-amino-3-methyl-1-oxobutan-2-yl)-1- (cyclohexylmethyl)-3-(4-fluorophenyl)-1H-pyrazole-5-carboxamide that was termed 3,5-AB-CHMFUPPYCA. This compound was obtained from a ... -
Preparation and characterization of the ‘research chemical’ diphenidine, its pyrrolidine analogue, and their 2,2-diphenylethyl isomers.
(Wiley, 2015-05)Substances with the diphenylethylamine nucleus represent a recent addition to the product catalog of dissociative agents sold as research chemicals on the Internet. Diphenidine, i.e. 1-(1,2-diphenylethyl)piperidine ... -
Synthesis, characterization and monoamine transporter activity of the new psychoactive substance mexedrone and its N-methoxy positional isomer, N-methoxymephedrone.
(Wiley, 2017-03)3-Methoxy-2-(methylamino)-1-(4-methylphenyl)propan-1-one (mexedrone) appeared in 2015 and was advertised by UK Internet retailers as a noncontrolled mephedrone derivative (2-(methylamino)-1-(4- methylphenyl)propan-1-one), ... -
Test purchase, synthesis and characterization of 3-fluorophenmetrazine (3-FPM) and differentiation from its ortho- and para-substituted isomers
(Wiley, 2017-03)The knowledge captured in patent and scientific research literature stimulates new ideas and fosters new drug development efforts. Manufacturers and entrepreneurs dedicated to the sale of ‘research chemicals’ and/or ... -
Synthesis, characterization and monoamine transporter activity of the new psychoactive substance 3’,4’-methylenedioxy-4-methylaminorex (MDMAR).
(Wiley, 2015-07)The recent occurrence of deaths associated with the psychostimulant cis-4,4'-dimethylaminorex (4,4'-DMAR) in Europe indicated the presence of a newly emerged psychoactive substance on the market. Subsequently, the existence ... -
Synthesis, analytical characterization and monoamine transporter activity of the new psychoactive substance 4- methylphenmetrazine (4-MPM), with differentiation from its ortho- and meta- positional isomers
(Wiley, 2018-09)The availability of new psychoactive substances on the recreational drug market continues to create challenges for scientists in the forensic, clinical and toxicology fields. Phenmetrazine (3-methyl-2-phenylmorpholine) ... -
Pulsed-light reduces the toxicity of the algal toxin okadaic acid to freshwater crustacean Daphnia pulex.
(Springer, 2018-01)This constitutes the first study to report on the reduction in toxicity of the dinoflagellate algal toxin okadaic acid after novel pulsed light (PL) treatments where ecotoxicological assessment was performed using a ... -
Detection, toxicology, environmental fate and risk assessment of nanoparticles in the aquatic environment (DeTER)
(EPA, 2018)Nanotechnology is an emerging technology that has the potential to impact on all aspects of life and the economy and is expected to form the basis of several technological innovations and advances in the 21st century. ...
