Chromosome 9p21.3 is associated with early-onset coronary heart disease in the Irish population

Coronary heart disease (CHD) remains a leading cause of death across the world. A region on chromosome 9p21.3 has been recently reported to be associated with CHD. We evaluated 3 SNPs and 3 common haplotypes in the 9p21.3 region in 1494 individuals from 580 Irish families, where at least 1 member had early-onset (males

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.

Antioxidants and periodontitis in 60-70 year- old men

Objective: The aim was to investigate the association between periodontal health and the serum levels of various antioxidants including carotenoids, retinol and vitamin E in a homogenous group of Western European men.
Materials and Methods: A representative sample of 1258 men aged 60-70 years, drawn from the population of Northern Ireland, was examined between 2001 and 2003. Each participant had six or more teeth, completed a questionnaire and underwent a clinical periodontal examination. Serum lipid-soluble antioxidant levels were measured by high-performance liquid chromatography with diode array detection. Multivariable analysis was carried out using logistic regression with adjustment for possible confounders. Models were constructed using two measures of periodontal status (low- and high-threshold periodontitis) as dependent variables and the fifths of each antioxidant as a predictor variable.
Results: The levels of a- and ß-carotene, ß-cryptoxanthin and zeaxanthin were highly significantly lower in the men with low-threshold periodontitis (p<0.001). These carotenoids were also significantly lower in high-threshold periodontitis. There were no significant differences in the levels of lutein, lycopene, a- and ?-tocopherol or retinol in relation to periodontitis. In fully adjusted models, there was an inverse relationship between a number of carotenoids (a- and ß-carotene and ß-cryptoxanthin) and low-threshold periodontitis. ß-Carotene and ß-cryptoxanthin were the only antioxidants that were associated with an increased risk of high-threshold severe periodontitis. The adjusted odds ratio for high-threshold periodontitis in the lowest fifth relative to the highest fifth of ß-cryptoxanthin was 4.02 (p=0.003).
Conclusion: It is concluded that low serum levels of a number of carotenoids, in particular beta-cryptoxanthin and beta-carotene, were associated with an increased prevalence of periodontitis in this homogenous group of 60-70-year-old Western European men.

What the Papers Say: Trends in Sustainability

This paper presents an overview of the results of a longitudinal analysis of the coverage of sustainability-related concepts in 115 leading national newspapers worldwide between January 1990 and July 2008, covering approximately 20,500,000 articles in 340,000 newspaper issues in 39 countries. On a global level, sustainable development and corporate social responsibility seem to have reached the mainstream public arena, whereas the coverage of corporate citizenship and corporate sustainability remains marginal. The increase in sustainability related media coverage since 1990 largely seems to be of an incremental nature, rather than clearly associated with specific events. Only very few truly global events can be identified that triggered a substantial amount of media coverage globally. Furthermore, marked regional and national differences in the coverage of sustainability related concepts can be identified.
