This paper describes the use of a peer research methodology to explore disaffected young people’s views on alternative education. This model was adopted in order to try to ensure an equilibrium of power between interviewer and interviewee, allow marginalised young people’s voices to be heard and help generate social action. The approach is examined from the perspective of both the peer research and adult research teams. An experiential and honest account is given including the problems and successes, as well as the lessons learned. The paper concludes by considering the value of the model, whether it helps to reach those alienated from education and any evidence that it provides an opportunity for them to have a stake in their future.

In this article, I examine Thomas Middleton's Women Beware Women as a response to the particular religio-political context in the years surrounding 1621. The onset of the Thirty Years War in 1618 and the subsequent humiliation of James' son-in-law Frederick, Elector of Palatine, the vexed question of a possible Catholic marriage for Charles, Prince of Wales, the ever present difficulty of Anglo-Catholic relations, particularly with Spain, as well as growing religious factionalism within the Church of England between Calvinists and Arminians: all contributed towards a culturally febrile atmosphere, one to which, as I will argue, Middleton was well placed to respond. Given Middleton's Calvinistic beliefs, I suggest that Women Beware Women offers an acerbic examination of contemporary debates concerning human will, especially women's will, as well as promoting a sceptically apocalyptic anti-Catholic agenda throughout. I also examine the religious language and imagery used to construct Bianca as the whore of Babylon, and argue that her emergence and fall offer a political commentary on the precarious position of the English Church around 1621.

BACKGROUND: Advanced glycation endproducts (AGEs) arise from the spontaneous reaction of reducing sugars with the amino groups of macromolecules. AGEs accumulate in tissue as a consequence of diabetes and aging and have been causally implicated in the pathogenesis of several of the end-organ complications of diabetes and aging, including cataract, atherosclerosis, and renal insufficiency. It has been recently proposed that components in mainstream cigarette smoke can react with plasma and extracellular matrix proteins to form covalent adducts with many of the properties of AGEs. We wished to ascertain whether AGEs or immunochemically related molecules are present at higher levels in the tissues of smokers.

MATERIALS AND METHODS: Lens and coronary artery specimens from nondiabetic smokers and nondiabetic nonsmokers were examined by immunohistochemistry, immunoelectron microscopy, and ELISA employing several distinct anti-AGE antibodies. In addition, lenticular extracts were tested for AGE-associated fluorescence by fluorescence spectroscopy.

RESULTS: Immunoreactive AGEs were present at significantly higher levels in the lenses and lenticular extracts of nondiabetic smokers (p < 0.003). Anti-AGE immunogold staining was diffusely distributed throughout lens fiber cells. AGE-associated fluorescence was significantly increased in the lenticular extracts of nondiabetic smokers (p = 0.005). AGE-immunoreactivity was significantly elevated in coronary arteries from nondiabetic smokers compared with nondiabetic nonsmokers (p = 0.015).

CONCLUSIONS: AGEs or immunochemically related molecules are present at higher levels in the tissues of smokers than in nonsmokers, irrespective of diabetes. In view of previous reports implicating AGEs in a causal association with numerous pathologies, these findings have significant ramifications for understanding the etiopathology of diseases associated with smoking, the single greatest preventable cause of morbidity and mortality in the United States.

This study evaluated dietary habits of Northern Irish men who are at high risk of cardiovascular disease, stratified as never-, ex-, moderate-, or heavy-smokers. Participants were male volunteers (30 - 49 years) from a single workforce in Belfast (n = 765). Dietary information was collected using a validated food frequency questionnaire. For 'a priori' diet scores, never- and ex-smokers had a significantly higher fruit and vegetable score, Mediterranean diet score, and alternative Mediterranean diet score than moderate or heavy-smokers (all p

This paper is concerned with the methodology underlying attempts to understand the nature and impact of racism among young children. In drawing upon data gathered from a year-long ethnographic study of five- and six-year-old children in an English multi-ethnic, inner-city primary school, the paper provides a critique of traditional approaches to the study of racial attitudes among young children. It is argued that such research has been conceived through the articulation of two, inter-related discourses on children and on 'race'; the former couched in traditional socialisation and developmental models of childhood with their tendency to neglect the agency and social competency of young children and the latter being embedded within essentialist notions of 'race' and ethnicity that tend to deny the contingent and context-specific nature of racialised identities. The paper argues that the result of this has been that while children have often been the objects of research they have rarely been the subjects; in other words they are often seen but never heard. The paper argues for the need to move beyond the methodological confines set by these discourses and rethink alternative approaches that begin with the assumption that young children are socially competent. One such approach, drawing upon ethnographic methods and fore-grounding the importance of largely unstructured small group interviews with young children, is illustrated. Through the use of a number of examples, it is shown how this approach can help to emphasise the ability of children as young as five and six to respond to and negotiate their social worlds and more specifically within this the competency with which they are able to appropriate, rework and reproduce a number of discourses on 'race' to make sense of their own social experiences. In doing this the paper also illustrates the way in which it provides a methodology able to draw out and highlight the contradictions, contingency and complexity of racialised identities among young children. Ultimately, it is an approach concerned with placing the children themselves central within the research processes and foregrounding their voices and experiences.

We hypothesised that primary bronchial epithelial cells (PBECs) from subjects with COPD respond differently to Pseudomonas aeruginosa lipopolysaccharide (PA LPS) after cigarette smoke extract (CSE) exposure than PBECs obtained from smokers without airflow obstruction (SWAO) and non-smokers (NS).PBECs from 16 COPD subjects, 10 SWAOand 9 NS were cultured at air-liquid interface. Cultures were incubated with CSE prior to stimulation with PA LPS. IL-6 and IL-8 were measured by ELISA and Toll-like receptor 4 expression by FACS. Activation of NF-?B was determined by western blotting and ELISA, and MAPK and caspase-3 activity by western blotting. Apoptosis was evaluated using Annexin-V staining and the terminal transferase-mediated dUTP nick end-labeling (TUNEL) methods.Constitutive release of IL-8 and IL-6 was greatest from the COPD cultures.However, CSE pre-treatment followed by PA LPS stimulation reduced IL-8 release from COPD PBECs, but increased it from cells of SWAOand NS. TLR-4 expression,MAPK and NF-?B activation in COPD cultures were reduced after CSE treatment, but not in the SWAOor NS groups, which was associated with increased apoptosis.CSE attenuates inflammatory responses to LPS in cells from people with COPD but not those from non-smoking individuals and those who smoke without airflow obstruction.

Chronic obstructive pulmonary disease (COPD) is predominantly caused by cigarette smoking and is considered a worldwide preventable chronic illness. Smoking cessation is considered the primary intervention for disease management and nurses should play a major role in assisting patients to stop smoking. Currently there is a lack of professional consensus on how cessation interventions should be evaluated. The vast array of biochemical markers reported in the literature can be confusing and can make the comparisons of results difficult.
