The ordination of women to the priesthood in the Church of England in 1994 signified great change. The impact of the new priests was well documented, and their integration became the focus of much research in the following years. One important area of change was the altered dynamics of gender identity. New roles had opened up for women, but new identities had also emerged for men. While women priests were a new historical emergence, so too were clergy husbands. This paper will consider the historical construction of masculinities and femininities within the church and will go on to look at this in the context of clergy spouses, specifically focusing on men occupying this role. Some provisional findings, acting as work in progress, will be considered.

This article analyzes the relationship between the Orthodox Church and the communist regime during one of the most intense periods of religious persecution in the Romanian People's Republic from 1956 to 1959. The church hierarchy demonstrated its support for the socialist construction of the country, while, at the same time, the regime began a campaign against religion by arresting clergy and reducing the number of religious people in monasteries; rumours even circulated that in 1958 Patriarch Justinian was under house arrest. Seeking closer contact with Western Europe, the regime allowed the hierarchy to meet foreign clergymen, especially from the Church of England. These diplomatic religious encounters played a double role. The regime realised that it could benefit from international ecclesiastical relations, while the image of Justinian in the West changed from that of "red patriarch" to that of a leader who was genuinely interested in his church's survival.

The tail-free operation of an overdriven gain-switched distributed feedback (DFB) laser by spectral filtering was demonstrated. The filtering was realized using a mechanically tunable fiber Bragg grating (FBG). The unfiltered and filtered signals were traced by corresponding oscilloscope. The spectral filtering removed the nonlinearly chirped components resulting in the pulse shortening. The results showed unwanted relaxation in the overdriven DFB laser were supressed by using a steep-edge notch filter.

In order to study the structure and function of a protein, it is generally required that the protein in question is purified away from all others. For soluble proteins, this process is greatly aided by the lack of any restriction on the free and independent diffusion of individual protein particles in three dimensions. This is not the case for membrane proteins, as the membrane itself forms a continuum that joins the proteins within the membrane with one another. It is therefore essential that the membrane is disrupted in order to allow separation and hence purification of membrane proteins. In the present review, we examine recent advances in the methods employed to separate membrane proteins before purification. These approaches move away from solubilization methods based on the use of small surfactants, which have been shown to suffer from significant practical problems. Instead, the present review focuses on methods that stem from the field of nanotechnology and use a range of reagents that fragment the membrane into nanometre-scale particles containing the protein complete with the local membrane environment. In particular, we examine a method employing the amphipathic polymer poly(styrene-co-maleic acid), which is able to reversibly encapsulate the membrane protein in a 10 nm disc-like structure ideally suited to purification and further biochemical study.

MRI of fluids containing lipid coated microbubbles has been shown to be an effective toot for measuring the local fluid pressure. However, the intrinsically buoyant nature of these microbubbles precludes lengthy measurements due to their vertical migration under gravity and pressure-induced coalescence. A novel preparation is presented which is shown to minimize both these effects for at least 25 min. By using a 2% polysaccharide gel base with a small concentration of glycerol and 1,2-distearoyl-sn-glycero-3-phosphocholine coated gas microbubbles, MR measurements are made for pressures between 0.95 and 1.44 bar. The signal drifts due to migration and amalgamation are shown to be minimized for such an experiment whilst yielding very high NMR sensitivities up to 38% signal change per bar.

This article examines the integration of women priests in the Church of England through the lens of dress. Clothing is a salient dynamic in occupational cultures, particularly in relation to the regulation of gendered bodies. Women's ordination to the priesthood was only sanctioned in 1992. Complex clothing regimes are negotiated, for ordination bestows upon the priest certain clothing rights and responsibilities. However, such attire has traditionally been associated only with the male body, creating tension in relation to women's appropriation of this sacred and professional dress. Based on in-depth interviews with 17 Anglican clergy women, this article will focus both on the scrutiny the women experienced in relation to their clothing choices, as well as the relationship the women themselves negotiated with their clothes. It will be argued that as representatives of both a sacred and professional domain, clothing had to be carefully managed by clergy. Dress functioned as a key test in women's integration into the organization, often operating as a constraining and exclusionary mechanism. © 2013 John Wiley & Sons Ltd.

Mg-Al hydrotalcite coatings have been grown on alumina via a novel alkali- and nitrate-free impregnation route and subsequent calcination and hydrothermal treatment. The resulting Mg-HT/AlO catalysts significantly outperform conventional bulk hydrotalcites prepared via co-precipitation in the transesterification of C-C triglycerides for fatty acid methyl ester (FAME) production, with rate enhancements increasing with alkyl chain length. This promotion is attributed to improved accessibility of bulky triglycerides to active surface base sites over the higher area alumina support compared to conventional hydrotalcites wherein many active sites are confined within the micropores. © 2014 The Royal Society of Chemistry.

ABC (ATP-binding-cassette) transporters carry out many vital functions and are involved in numerous diseases, but study of the structure and function of these proteins is often hampered by their large size and membrane location. Membrane protein purification usually utilizes detergents to solubilize the protein from the membrane, effectively removing it from its native lipid environment. Subsequently, lipids have to be added back and detergent removed to reconstitute the protein into a lipid bilayer. In the present study, we present the application of a new methodology for the extraction and purification of ABC transporters without the use of detergent, instead, using a copolymer, SMA (polystyrene-co-maleic acid). SMA inserts into a bilayer and assembles into discrete particles, essentially solubilizing the membrane into small discs of bilayer encircled by a polymer, termed SMALPs (SMA lipid particles). We show that this polymer can extract several eukaryotic ABC transporters, P-glycoprotein (ABCB1), MRP1 (multidrug-resistance protein 1; ABCC1), MRP4 (ABCC4), ABCG2 and CFTR (cystic fibrosis transmembrane conductance regulator; ABCC7), from a range of different expression systems. The SMALP-encapsulated ABC transporters can be purified by affinity chromatography, and are able to bind ligands comparably with those in native membranes or detergent micelles. A greater degree of purity and enhanced stability is seen compared with detergent solubilization. The present study demonstrates that eukaryotic ABC transporters can be extracted and purified without ever being removed from their lipid bilayer environment, opening up awide range of possibilities for the future study of their structure and function. © The Authors Journal compilation © 2014 Biochemical Society.

Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is an enzyme which catalyses the conversion of glyceraldehyde-3-phosphate to 1,3 diphosphoglycerate. It is considered to be constitutively expressed in all cells, and as such the gene for GAPDH (gapd) is commonly used as a benchmark reference in expression studies. However, previous investigations have demonstrated that gapd may show altered gene expression in a number of disease states and under certain experimental conditions, suggesting that results of experiments using gapd as a control should be interpreted with caution. Furthermore, consideration must be given to the potential co-amplification of pseudogenes of gapd during RT-PCR. Here, we describe a method to avoid the amplification of contaminating pseudogenes through the design of primers that bind only to genuine gapd mRNA transcript. © 2003 Elsevier Ltd.
