On the unimpairable resistance of the guinea pig to dietary amino azo dye hepatocarcinogenesis

Die Resistenz des Meerschweinchens gegenüber der hepatocarcinogenen Wirkung von 3′-Methyl-4-dimethylaminoazobenzene, das mit 0,12% insgesamt 8 Monate gefüttert wurde, wird auch durch den starken co-carcinogenen Einfluß einer Partialhepatektomie nicht gebrochen. The resistance of the guinea pig to carcinogenesis by 3′-methyl-4-dimethylaminoazobenzene fed at the level of 0.12% for a total of 8 months is not overcome by the potent cocarcinogenic influence of partial hepatectomy performed at 4 weeks.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/47536/1/432_2004_Article_BF00524400.pd

Genetic Control of mRNA Splicing as a Potential Mechanism for Incomplete Penetrance of Rare Coding Variants

Exonic variants present some of the strongest links between genotype and phenotype. However, these variants can have significant inter-individual pathogenicity differences, known as variable penetrance. In this study, we propose a model where genetically controlled mRNA splicing modulates the pathogenicity of exonic variants. By first cataloging exonic inclusion from RNA-sequencing data in GTEx V8, we find that pathogenic alleles are depleted on highly included exons. Using a large-scale phased whole genome sequencing data from the TOPMed consortium, we observe that this effect may be driven by common splice-regulatory genetic variants, and that natural selection acts on haplotype configurations that reduce the transcript inclusion of putatively pathogenic variants, especially when limiting to haploinsufficient genes. Finally, we test if this effect may be relevant for autism risk using families from the Simons Simplex Collection, but find that splicing of pathogenic alleles has a penetrance reducing effect here as well. Overall, our results indicate that common splice-regulatory variants may play a role in reducing the damaging effects of rare exonic variants

A cycle of brain gain, waste and drain - a qualitative study of non-EU migrant doctors in Ireland.

BACKGROUND: Ireland is heavily reliant on non-EU migrant health workers to staff its health system. Shortages of locally trained health workers and policies which facilitate health worker migration have contributed to this trend. This paper provides insight into the experiences of non-EU migrant doctors in the Irish health workforce. METHOD: In-depth interviews were conducted with 37 non-EU migrant doctors in Ireland in 2011/2012. RESULTS: Respondents believed they had been recruited to fill junior hospital doctor 'service' posts. These posts are unpopular with locally trained doctors due to the limited career progression they provide. Respondents felt that their hopes for career progression and postgraduate training in Ireland had gone unrealised and that they were becoming de-skilled. As a result, most respondents were actively considering onward migration from Ireland. DISCUSSION & CONCLUSIONS: Failure to align the expectations of non-EU migrant doctors with the requirements of the health system has resulted in considerable frustration and a cycle of brain gain, waste and drain. The underlying reasons for high mobility into and out of the Irish medical workforce must be addressed if this cycle is to be broken. The heavy reliance on non-EU migrant doctors to staff the medical workforce has distracted from the underlying workforce challenges facing the Irish medical workforce
