Protestantism, Spectacle, Motherhood and Vice: Dublin's New Pleasure Gardens

In 1748, Bartholomew Mosse, a curious combination of surgeon, obstetrician and entertainment impresario, established a pleasure garden on the northern fringes of Dublin. Ostensibly designed to fund the construction of a maternity hospital to be located adjacently, Mosse’s New Pleasure Gardens became one of the premier leisure resorts in Dublin. This was to have a profound effect on the city’s urban form. Within a few years the gardens became an epicentre of speculative development as the upper classes jostled to build their houses in the vicinity. Meanwhile, the creation nearby of Sackville Mall, a wide and generous strolling ground, established a whole section of the city dedicated to haute spectacle, display and leisure. Like other pleasure gardens in the British Isles, Mosse’s venture introduced new, commodified forms of entertainment. In the colonial context of eighteenth-century Ireland, however, ‘a land only recently won and insecurely held’ (Foster, 1988) by the Protestant Anglo-Irish settler class, the production of culture and spectacle was perhaps more significant than elsewhere. Indeed, the form of Mosse’s gardens echoed the private city gardens of a key figure in the Anglo-Irish aristocracy, while the hospital itself was constructed in a style of a Palladian country house, symbol of colonial presence in the countryside. However, like other pleasure gardens, the mix of music and alcohol, the heterogeneous crowd culled from across social and gender boundaries, and a landscape punctuated with secluded corners, meant that it also acquired a dubious reputation as a haunt of louche and illicit behaviours. The curious juxtaposition between a maternity hospital and pleasure garden, therefore, begins to assume other, hitherto hidden complexities. These are borne out by a closer examination of the architecture of the hospital, the shape of its landscape and the records of its patrons and patients.

Extracellular cathepsin S and intracellular caspase 1 activation are surrogate biomarkers of particulate-induced lysosomal disruption in macrophages

BACKGROUND: Particulate matter has been shown to stimulate the innate immune system and induce acute inflammation. Therefore, while nanotechnology has the potential to provide therapeutic formulations with improved efficacy, there are concerns such pharmaceutical preparations could induce unwanted inflammatory side effects. Accordingly, we aim to examine the utility of using the proteolytic activity signatures of cysteine proteases, caspase 1 and cathepsin S (CTSS), as biomarkers to assess particulate-induced inflammation.

METHODS: Primary peritoneal macrophages and bone marrow-derived macrophages from C57BL/6 mice and ctss(-/-) mice were exposed to micro- and nanoparticulates and also the lysosomotropic agent, L-leucyl-L-leucine methyl ester (LLOME). ELISA and immunoblot analyses were used to measure the IL-1β response in cells, generated by lysosomal rupture. Affinity-binding probes (ABPs), which irreversibly bind to the active site thiol of cysteine proteases, were then used to detect active caspase 1 and CTSS following lysosomal rupture. Reporter substrates were also used to quantify the proteolytic activity of these enzymes, as measured by substrate turnover.

RESULTS: We demonstrate that exposure to silica, alum and polystyrene particulates induces IL-1β release from macrophages, through lysosomal destabilization. IL-1β secretion positively correlated with an increase in the proteolytic activity signatures of intracellular caspase 1 and extracellular CTSS, which were detected using ABPs and reporter substrates. Interestingly IL-1β release was significantly reduced in primary macrophages from ctss(-/-) mice.

CONCLUSIONS: This study supports the emerging significance of CTSS as a regulator of the innate immune response, highlighting its role in regulating IL-1β release. Crucially, the results demonstrate the utility of intracellular caspase 1 and extracellular CTSS proteolytic activities as surrogate biomarkers of lysosomal rupture and acute inflammation. In the future, activity-based detection of these enzymes may prove useful for the real-time assessment of particle-induced inflammation and toxicity assessment during the development of nanotherapeutics.

Teenage motherhood: where you live is also important. A prospective cohort study of 14,000 women

The United Kingdom has among the highest rates of teenage motherhood (TM) in Western Europe. The relationship to individual social and material disadvantage is well established but the influence of area of residence is unclear. We tested for additional TM risks in deprived areas or in cities. The Northern Ireland Longitudinal Study was used to identify 14,055 nulliparous females (15-18). TM risk was measured using multilevel logistic regression, adjusting for health status, religion, family structure, socio-economic status, rurality and employment-based area deprivation. Most variation in TM was driven by individual, household and socioeconomic factors with the greatest proportion of mothers in low value or social rented accommodation. Living in an area with fewer employment opportunities was associated with elevated TM risk (most vs. least deprived, ORadj = 1.98 [1.49, 2.63]), as was urban dwelling (urban vs. intermediate, ORadj = 1.42 [1.13, 1.78]). We conclude that area of residence is a significant independent risk factor for TM. Interventions should be targeted towards the most deprived and urban areas and to those in the lowest value housing.

Symbolic violence and the neighbourhood: young working class girls' attitudes to education in Belfast

This article focuses on the experiences of 7-8 year old working-class girls in Belfast, Northern Ireland and their attitudes towards education. It shows how their emerging identities tend to emphasize relationships, marriage and motherhood at the expense of a concern with education and future careers. The article suggests that one important factor that can help explain this is the influence of the local neighbourhood. In drawing upon Bourdieu's concepts of symbolic violence and habitus and Elias' notion of figuration, the article shows how the local neighbourhood represents the parameters of the girls' social worlds. It provides the context within which the girls tend to focus on social relations within their community and particularly on family relationships, marriage and children. It also provides the context within which the girls tend to develop strong interdependent relationships with their mothers that also tend to encourage and reinforce the girls' particular gendered identities. The article concludes by arguing that there is a need for more research on working-class girls and education to look beyond the school to incorporate, more fully, an understanding of the influence of the family and local neighbourhood on their attitudes towards education and their future career aspirations.

Cloning from tissue surrogates: antimicrobial peptide (esculentin) cDNAs from the defensive skin secretions of Chinese ranid frogs

The defensive skin secretions of amphibians are a rich source of bioactive peptides. Here we describe a rapid technique for skin granular gland transcriptome cloning from a surrogate tissue-the secretion itself. cDNA libraries were constructed from lyophilized skin secretion from each of the Chinese frogs (Rana schmackeri, Rana versabilis, and Rana plancyi fukienensis) using magnetic oligo(dT) bead-captured polyadenylated mRNA as templates. Specific esculentin cDNAs were amplified by 3'-RACE using a degenerate primer designed for a consensus nucleotide sequence in the 5' untranslated region of previously characterized ranid frog peptide cDNAs. The cloned cDNAs were found to encode the antimicrobial peptides esculentins 1 and 2 from each of the species examined. The presence of predicted peptide structures in skin secretions was confirmed by MALDI-TOF mass spectrometry and automated Edman degradation. This experimental approach can thus rapidly expedite parallel transcriptome and peptidome analysis of amphibian granular gland secretions without harming or sacrificing donor animals.

Epidermal Growth Factor Receptor Activity Determines Response of Colorectal Cancer Cells to Gefitinib Alone and in Combination with Chemotherapy.

Purpose: Up to now, there have been no established predictive markers for response to epidermal growth factor receptor (EGFR/HER1/erbB1) inhibitors alone and in combination with chemotherapy in colorectal cancer. To identify markers that predict response to EGFR-based chemotherapy regimens, we analyzed the response of human colorectal cancer cell lines to the EGFR-tyrosine kinase inhibitor, gefitinib (Iressa, AstraZeneca, Wilmington, DE), as a single agent and in combination with oxaliplatin and 5-fluorouracil (5-FU). Experimental Design: Cell viability was assessed using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide and crystal violet cell viability assays and analyzed by ANOVA. Apoptosis was measured by flow cytometry, poly(ADP-ribose) polymerase, and caspase 3 cleavage. EGFR protein phosphorylation was detected by Western blotting. Results: Cell lines displaying high constitutive EGFR phosphorylation (a surrogate marker for EGFR activity) were more sensitive to gefitinib. Furthermore, in cell lines exhibiting low constitutive EGFR phosphorylation, an antagonistic interaction between gefitinib and oxaliplatin was observed, whereas in cell lines with high basal EGFR phosphorylation, the interaction was synergistic. In addition, oxaliplatin treatment increased EGFR phosphorylation in those cell lines in which oxaliplatin and gefitinib were synergistic but down-regulated EGFR phosphorylation in those lines in which oxaliplatin and gefitinib were antagonistic. In contrast to oxaliplatin, 5-FU treatment increased EGFR phosphorylation in all cell lines and this correlated with synergistic decreases in cell viability when 5-FU was combined with gefitinib. Conclusions: These results suggest that phospho-EGFR levels determine the sensitivity of colorectal cancer cells to gefitinib alone and that chemotherapy-mediated changes in phospho-EGFR levels determine the nature of interaction between gefitinib and chemotherapy.

Cyclooxygenase-2 expression correlates with phaeochromocytoma malignancy.

Abstract Aims: Phaeochromocytomas are rare but potentially life-threatening neuroendocrine tumours of the adrenal medulla or sympathetic nervous system ganglia. There are no histological features which reliably differentiate benign from malignant phaeochromocytomas. The current study evaluated cyclooxygenase-2 (Cox-2) and Bcl-2 as tissue-based biomarkers of phaeochromocytoma prognosis. Methods and Results: Cox-2 and Bcl-2 expression were examined immunohistochemically in tissue from forty-one sporadic phaeochromocytoma patients followed up for a minimum of five years after diagnosis. There was a statistically significant association between Cox-2 histoscore (intensity x porportion) and the development of tumour recurrence or metastases (p=0.006). A significant relationship between the co-expression of Cox-2 and Bcl-2 in the primary tumour and the presence of recurrent disease was observed (p=0.034). A highly significant association was observed between, (i) the tumour-associated expression of these two oncoproteins (p=0.001) and, (ii) Cox-2 histoscore and the presence of Bcl-2 expression (p=0.002). Cox regression analysis demonstrated no significant relationship between, (i) the presence or absence of either Cox-2 or Bcl-2 and patient survival or, (ii) between Cox-2 histoscore and patient survival. Conclusions: These results suggest that Cox-2 and Bcl-2 may promote phaeochromocytoma malignancy and that these oncoproteins may be valuable surrogate markers of an aggressive tumour phenotype.

A Longitudinal and Contextual Analysis of Media Representation of Business Ethics

Purpose – The purpose of this paper is to present an analysis of media representation of business ethics within 62 international newspapers to explore the longitudinal and contextual evolution of business ethics and associated terminology. Levels of coverage and contextual analysis of the content of the articles are used as surrogate measures of the penetration of business ethics concepts into society. Design/methodology/approach – This paper uses a text mining application based on two samples of data: analysis of 62 national newspapers in 21 countries from 1990 to 2008; analysis of the content of two samples of articles containing the term business ethics (comprised of 100 newspaper articles spread over an 18-year period from a sample of US and UK newspapers). Findings – The paper demonstrates increased coverage of sustainability topics within the media over the last 18 years associated with events such as the Rio Summit. Whilst some peaks are associated with business ethics scandals, the overall coverage remains steady. There is little apparent use in the media of concepts such as corporate citizenship. The academic community and company ethical codes appear to adopt a wider definition of business ethics more akin to that associated with sustainability, in comparison with the focus taken by the media, especially in the USA. Coverage demonstrates clear regional bias and contextual analysis of the articles in the UK and USA also shows interesting parallels and divergences in the media representation of business ethics. Originality/value – A promising avenue to explore how the evolution of sustainability issues including business ethics can be tracked within a societal context.

The prevalence of nonadherence in difficult asthma

Rationale: With the advent of new and expensive therapies for severe refractory asthma, targeting the appropriate patients is important. An important issue is identifying nonadherence with current therapies. The extent of nonadherence in a population with difficult asthma has not been previously reported.

Objectives: To examine the prevalence of nonadherence to corticosteroid medication in a population with difficult asthma referred to a Specialist Clinic and to examine the relationship of poor adherence to asthma outcome.

Methods: General practitioner prescription refill records for the previous 6 months for inhaled combination therapy and short-acting ß-agonists were compared with initial prescriptions and expressed as a percentage. Blood plasma prednisolone and cortisol assay levels were used to examine the utility of these measures in assessing adherence to oral prednisolone. Patient demographics, hospital admissions, lung function, oral prednisolone courses, and quality of life data were analyzed to indentify the variables associated with reduced medication adherence.

Measurements and Main Results: A total of 182 patients were assessed. Sixty-three patients (35%) filled 50% or fewer inhaled medication prescriptions; 88% admitted poor adherence with inhaled therapy after initial denial. Twenty-one percent of patients filled more than 100% of presciptions, and 45% of subjects filled between 51 and 100% of prescriptions. Twenty-three of 51 patients (45%) prescribed oral steroids were found to be nonadherent.

Conclusions: A significant proportion of patients with difficult-to-control asthma remained nonadherent to corticosteroid therapy. Objective surrogate and direct measures of adherence should be performed as part of a difficult asthma assessment and are important before prescibing expensive novel biological therapies.

Probing aggressive motivation in a cichlid fish

The duration of startles provides an inverse measure of motivation to resume the previous activity. Here, we use a novel method in which one convict cichlid fish (Amatitlania nigrofasciata) of a competing pair was startled independently of the opponent. Fish were given various opponents and the mean startle duration determined. This mean was negatively correlated with the mean use of highly escalated 'frontal activities' such as biting and frontal display, but not the less escalated lateral displays or tail beating. Thus the startle duration was a reliable surrogate measure of the most escalated components of aggressive interactions. That is, it provided a motivational probe for aggressiveness of individual fish. Fight motivation is often determined in terms of fight duration or physiological costs for losers, who reveal the costs they are prepared to pay. We discuss various potential advantages of the motivational probe over previous measures, particularly with respect to winners and losers and different times during the interactions.

Molecular cloning of the helokinestatin/CNP precursor from a venom-derived cDNA library of the Mexican beaded lizard, Heloderma horridum, and identification of a novel encoded bradykinin-antagonist peptide, helokinestatin-6

Helokinestatins 1–5 represent a novel family of bradykinin antagonist peptides originally isolated from the venom of the Gila Monster, Heloderma suspectum. We found that they were encoded in tandem along with a single copy of C-type natriuretic peptide (CNP), by two different but almost identical biosynthetic precursors that were cloned from a venom-derived cDNA library. Here we have applied the same strategy to the venom of a related species, the Mexican beaded lizard, Heloderma horridum. Lyophilised venom was used as a surrogate tissue to generate a cDNA library that was interrogated with primers from the previous study and for reverse phase HPLC fractionation. The structure of a single helokinestatin precursor was obtained following sequencing of 20 different clones. The open-reading frame contained 196 amino acid residues, somewhat greater than the 177–178 residues of the corresponding helokinestatin precursors in H. suspectum. The reason for this difference in size was the insertion of an additional domain of 18 amino acid residues encoding an additional copy of helokinestatin-3. Helokinestatin-6 (GPPFNPPPFVDYEPR) was a novel peptide from this precursor identified in venom HPLC fractions. A synthetic replicate of this peptide antagonised the relaxation effect of bradykinin on rat arterial smooth muscle. The novel peptide family, the helokinestatins, have been shown to be present in the venom of H. horridum and to be encoded by a single precursor of different structure to those from H. suspectum. Studies such as this reveal the naturally-selected structures of bioactive peptides that have been optimised for purpose and provide the scientist with a natural analogue library for pharmacological investigation.

Effect of pioglitazone on endothelial function in impaired glucose tolerance

Aim: Flow-mediated dilation (FMD) is a surrogate marker of endothelial function, which has been proposed as a barometer of vascular health. Impaired microvascular response to reactive hyperaemia is thought to be the mechanism behind reduced shear stress and subsequently impaired FMD, which has been associated with cardiovascular events. This study aims to assess the effect of pioglitazone on the vasculature of patients with impaired glucose tolerance (IGT).

Materials and Methods: Forty IGT patients with no cardiovascular disease were compared with 24 healthy age- and sex-matched controls. Endothelial function was assessed using FMD of the brachial artery. Adiponectin (ADN) levels were measured and insulin sensitivity was calculated using homeostasis model assessment of insulin resistance (HOMA-IR). A randomised double-blind placebo-controlled trial of the IGT subjects was then performed, with subjects receiving either pioglitazone 30 mg od or matched placebo for 12 weeks before the measurements were repeated.

Results: The IGT subjects had a significantly impaired FMD compared with the controls (p < 0.001). Diastolic shear stress (DSS) was also significantly reduced in IGT (p = 0.04). High molecular weight (HMW) ADN was significantly lower in the IGT group than in controls (p = 0.03). On analysis of the IGT group after 12 weeks treatment, FMD was significantly increased in the pioglitazone group compared with placebo (p = 0.03) as was endothelium-independent dilation (EID) (p = 0.03). A significant increase in total ADN (p < 0.001), HMW ADN (p < 0.001) and HMW/total ratio (p = 0.001) occurred in the pioglitazone group compared with placebo.

Conclusions: Pioglitazone improved endothelial function in IGT. Treatment with pioglitazone may reduce the risk of cardiovascular disease in this patient group.

Early crime writing and the state: Jonathan Wild, Daniel Defoe and Bernard Mandeville in 1720s London

This article argues that the early development of crime writing needs to be understood in relation to the consolidation of the modern state. It demonstrates that London in the 1720s constitutes a significant moment in this early development for three main reasons. First, the period witnessed a crime epidemic which reached its climax in the 1720s and which precipitated a set of particularly aggressive counter-measures by the state; second, it saw the rise and eventual fall of the infamous Jonathan Wild who acted as both thief and surrogate policeman; and third, it was also marked by a surge in interests on the part of writers like Daniel Defoe and Bernard Mandeville in the related matters of crime and punishment. This article explores the ways in which accounts of crime and punishment in this period deployed and in some instances interrogated the rhetoric of social contract theory and writings on statecraft, particularly by Thomas Hobbes and Mandeville. But while the criminal biographies and gallows sermons produced by the Newgate prison’s ‘ordinaries’ provided crude and reductive accounts of the efficacy of the state, the article shows how two accounts of the life of Jonathan Wild (by Defoe and H.D) responded in highly complex ways to the issues of crime and policing and provided a consistently and self-consciously ambivalent reading of the state and state power. To conclude, I suggest that this ambivalence can be read as a critique of the impartial or neutral state and that it constitutes one of the key features of what we would later understand to be crime writing as a dedicated literary genre.

Taking the Next Step? Achieving another Bill of Rights

The aim of this article is to explore the recent Bill of Rights debate in the UK. This is deliberately located in the UK’s complex ‘national question’ because of the obsessive focus on achieving a proper grounding for human rights. A new form of national human rights protectionism appears to be emerging and merits careful consideration. The article suggests that it is better to acknowledge and accept the existence of a plurality of nationalisms in the UK in these discussions and understand how an essentially ‘British nationalist’ discourse sounds and works in that overall context. The concern is that the Bill of Rights debate is becoming an inadequate surrogate for the more challenging constitutional conversations that are required, and human rights discourse thus invested with expectations of national renewal that it can never meet and does not have the internal resources to resolve. If the process does go forward it may be better to prepare the ground for a deeper and wider constitutional dialogue across these islands than stumble clumsily and divisively into this territory simply via ‘another’ UK Bill of Rights.
