Expansion of physiological knowledge increasingly requires examination of processes in the normal, conscious state. The current study describes a novel approach combining surgical implantation of radio-telemeters with vascular access ports (VAPs) to allow repeated hemodynamic and pharmacological measures in conscious rats. Dual implantation was conducted on(More)
Replacement, Reduction and Refinement, the ‘Three Rs’ of Russell & Burch, are accepted worldwide as fundamental to the ethics of animal experimentation. The production, care and use of genetically-altered animals can pose particular challenges to the implementation of the Three Rs,1 necessitating additional considerations by those responsible for overseeing(More)
This paper aims to better understand the theoretical heat-energy demand of different types of urban form at a scale of 500 by 500 metres. The empirical basis of this study includes samples of dominant residential building typologies identified for Paris, London, Berlin and Istanbul. In addition, archetypal idealised samples were created for each type(More)
A randomised, single-blinded, controlled trial was conducted to determine if a new laryngeal mask deflation tool offered any advantages over manual or free deflation. Ten laryngeal mask airways were tested and the deflation tool provided a significantly superior and more consistent shape than either hand manipulation or the free deflation, but did not offer(More)
The work described here is effectively the computerization of a gas/liquid chromatograph of the pen recorder type using a BBC microcomputer. The output from the g.l.c. can be captured by the computer in accordance with a series of parameters. The sampling rate can be altered, as can an averaging facility to reduce noise, and a threshold level to eliminate(More)
The syntheses of stable isotope labelled internal standards of important CYP-isoform selective probes, like testosterone 1, diclofenac 3, midazolam 5, and dextromethorphan 7, as well as their corresponding hydroxylated metabolites 6β-hydroxytestosterone 2, 4'-hydroxydiclofenac 4, 1'-hydroxymidazolam 6 and dextrorphan 8 are reported. Microwave-enhanced(More)
We present an interesting Sunyaev–Zel’dovich (SZ) detection in the first of the Arcminute Microkelvin Imager (AMI) ‘blind’, degree-square fields to have been observed down to our target sensitivity of 100μJy beam−1. In follow-up deep pointed observations the SZ effect is detected with a maximum peak decrement greater than eight times the thermal noise. No(More)
