IgA antibodies to TG3 are elevated in patients with DH and adults with CD. The progressive expansion of the epitope-binding profile of IgA antitransglutaminase antibodies in patients with CD may explain the development of DH in patients with undiagnosed CD during their adult life.

Large-scale migration of workers from new EU member states to the Nordic countries, mostly to fill relatively low-skilled jobs in construction, manufacturing and services, has raised concerns of low-wage competition and the ability of the Nordic social model to uphold labour standards. This article explores variations in wages and working conditions among Polish migrant workers in Oslo, Copenhagen and Reykjavik. The analysis highlights how different institutional configurations within the Nordic labour markets shape the outcomes for migrant workers, and raises questions regarding the ability of the different variations of the Nordic labour market regime to protect workers in an open, unequal and mobile European labour market.

Hexaploid wheat genotypes from north‐western Europe show low responses to current anther culture techniques. This phenomenon was investigated on 145 north‐western European wheat lines. Twenty‐seven lines from eastern Europe were included to observe the response pattern of wheat from an area, where the technique has been used successfully. On average, eastern European wheat lines produced 3.6 green plants per 111 anthers, while only 1.4 green plants per 111 anthers were obtained in north‐western European lines. This difference was due to the high capacity for embryo formation among the eastern European lines, while the ability to regenerate green plants was widespread in both germplasm groups. Isolated wheat microspore culture performed on 85 of these wheat lines gave an average 3.7‐fold increase in green plants per anther compared with the anther culture response. The increased recovery of green plants was due to improved plant regeneration and increased green plant percentage from embryos derived from isolated microspore culture.

Based on a respondent driven sampling survey with 500 Polish migrant workers in Denmark, this article argues that specific labour market institutions and sector differences need to be taken into account when explaining the working conditions of migrant workers. Comparing the working conditions of Polish and Danish workers, it is shown that labour market institutional arrangements provide a better explanation for the differences found between the two groups than differences in individual characteristics of the migrants and the Danish workforce. In addition, the article argues that factors such as institutionalized wage variability within sectors and the decentralized regulation of working conditions are important when assessing the potential implication of migrant workers in the labour market.

This article analyses the impact of the economic crisis on the public sector in Denmark. It first examines the overall public sector responses and presents local case studies, before offering a comparative perspective with other Nordic countries. The article concludes that responses to the crisis in Denmark mostly involve 'resetting recent reform'. The crisis has affected on job levels and employment relations, but other drivers are also important. Analysis at the local level reveals that the reduction in job levels is as much an expression of the implementation of pre-crisis reforms and demographic change as a manifestation of a direct crisis impact. The moderate impact of the crises on public sector reforms is also found in Norway, Finland and Sweden.

Isolated microspore cultures from two doubled haploid (DH) lines of wheat, Triticum aestivum L., were used to develop an in vitro chromosome-doubling protocol. During the initial 24 h or 48 h of culture the microspores were treated with either of the two antimicrotubule herbicides trifluralin or amiprophos-methyl (APM) in concentrations ranging from 0.1 /zM to 10/iM. Untreated control cultures yielded 209 embryos per 100000 microspores, which is the equivalent of one spike. Among the regenerated plantlets 67% were green, and 15% of the flowering plants were spontaneously chromosome doubled. Treatments with both the herbicides had a significant effect on chromosome doubling, measured as the percentage of fertile regenerants. With the best combination of treatment duration (48 h) and herbicide concentration (10/iM) the percentage of fertile plants among regenerants could be increased up to 74% with APM and up to 65% with trifluralin. The largest numbers of DH plants per spike could be obtained with herbicide concentrations at 1-3/iM. Treatments with either herbicide at these concentrations resulted in an estimated average between the two genotypes of 27 DH plants per 100000 microspores. These results demonstrate the high potential of APM and trifluralin as chromosomedoubling agents in isolated microspore cultures. The in vitro treatment integrated into tissue culture procedures will constitute an efficient method for chromosome doubling in future wheat breeding
