A new UHPLC-MS/MS (ultra high performance liquid chromatography coupled to tandem mass spectrometry) method was developed and validated to detect 38 anthelmintic drug residues, consisting of benzimidazoles, avermectins and flukicides. A modified QuEChERS-type extraction method was developed with an added concentration step to detect most of the analytes at(More)
In this study, dairy cows (n = six) were treated with an oral combination product containing levamisole (5 mg/kg body weight, (bw)) and oxyclozanide (10 mg/kg bw). Animals were milked twice daily up to day 16 post-treatment. Milk samples were subsequently analyzed by ultraperformance liquid chromatography coupled to tandem mass spectrometry (UPLC-MS/MS).(More)
This report investigates the effectiveness of road safety public information campaigns conducted through the mass media. The differing roles of publicity in the fields of brand advertising and public health promotion are identified and discussed in the context of theories of behaviour change. A number of widely used micro level models of social persuasion(More)
A surface plasmon resonance (SPR) biosensor screening assay was developed and validated to detect 11 benzimidazole carbamate (BZT) veterinary drug residues in milk. The polyclonal antibody used was raised in sheep against a methyl 5(6)-[(carboxypentyl)-thio]-2-benzimidazole carbamate protein conjugate. A sample preparation procedure was developed using a(More)
Anthelmintic drugs are widely used for treatment of parasitic worms in livestock, but little is known about the stability of their residues in food under conventional cooking conditions. As part of the European Commission-funded research project ProSafeBeef, cattle were medicated with commercially available anthelmintic preparations, comprising 11 active(More)
OBJECTIVES While there is much emphasis on managing the safety of older road users, there is limited understanding and recognition of the significance of mobility and transportation needs, mobility changes in later life, and the impact of reduced mobility on quality of life. Moreover, there is little information about the measures that can be taken to(More)
The ability to travel is associated with freedom, activity and choice and driving offers an important mobility option for most elderly. Driving cessation is linked to an increase in depressive symptoms and a decline in out-of-home activity levels and community mobility. Further, for at least some people, the same health conditions and functional impairments(More)
In the field of food contaminant analysis, the most significant development of recent years has been the integration of ultra-high pressure liquid chromatography (UHPLC), coupled to tandem quadrupole mass spectrometry (MS/MS), into analytical applications. In this review, we describe the emergence of UHPLC through technological advances. The implications of(More)
Toluidine blue is an important tool to detect and document genital and perianal injuries following sexual assault. Application of toluidine blue dye and its subsequent removal from unstained areas by means of a destaining reagent, such as diluted acetic acid or a lubricant has been shown to increase the detection rate of posterior fourchette lacerations(More)
Anthelmintic drugs are widely used to control parasitic infections in cattle. The ProSafeBeef project addressed the need for data on the exposure of European consumers of beef to potentially harmful drug residues. A novel analytical method based on matrix solid-phase dispersive extraction and ultra-performance liquid chromatography-tandem mass spectrometry(More)
