The Consumption, Production and Regulation of Alcohol in the UK: The Relevance of the Ambivalence of the Carnivalesque

Alcohol consumption in 21st-century Britain is of significant interest to government, media and academics. Some have referred to a ‘new culture of intoxication’ or ‘calculated hedonism’, fostered by the drinks industry, and enabled by a neoliberal policymaking context. This article argues that the ‘carnivalesque’ is a better concept through which to understand alcohol’s place in British society today. The concept of the carnivalesque conveys an earthy yet extraordinary culture of drinking, as well as ritual elements with a lack of comfort and security that characterise the night-time economy for many people. This night-time carnival, as well as being something experienced by participants, is also a spectacle, with gendered and classed dynamics. It is suggested that this concept is helpful in making sense of common understandings of alcohol that run through the spheres not only of alcohol consumption but also production and regulation

A continuous fluorescence resonance energy transfer angiotensin I-converting enzyme assay

Angiotensin I-converting enzyme (ACE) is involved in various physiological and physiopathological conditions; therefore, the measurement of its catalytic activity may provide essential clinical information. This protocol describes a sensitive and rapid procedure for determination of ACE activity using fluorescence resonance energy transfer ( FRET) substrates containing o-aminobenzoic acid (Abz) as the fluorescent group and 2,4-dinitrophenyl (Dnp) as the quencher acceptor. Hydrolysis of a peptide bond between the donor/acceptor pair generates fluorescence that can be detected continuously, allowing quantitative measurement of the enzyme activity. the FRET substrates provide a useful tool for kinetic studies and for ACE determination in biological fluids and crude tissue extracts. An important benefit of this method is the use of substrates selective for the two active sites of the enzyme, namely Abz-SDK( Dnp) P-OH for N-domain, Abz-LFK( Dnp)-OH for C-domain and Abz-FRK(Dnp) P-OH for somatic ACE. This methodology can be adapted for determinations using a 96-well fluorescence plate reader.Univ Cape Town, Inst Infect Dis & Mol Med, Div Med Biochem, ZA-7925 Cape Town, South AfricaUniversidade Federal de São Paulo, Escola Paulista Med, Dept Biophys, São Paulo, BrazilUniversidade Federal de São Paulo, Escola Paulista Med, Dept Biophys, São Paulo, BrazilWeb of Scienc
