The Global Predicament: the way out

Most "green" thought and action fails to grasp that this society involves levels of resource consumption and environmental impact that are far beyond those that can be sustained or spread to all people. Technical advance and reforms within consumer-capitalist society cannot solve the problems; this will be illustrated by reference to greenhouse and energy problems. Although present levels of consumption are grossly unsustainable, the supreme priority is economic growth, i.e. to raise them without limit. In addition a system based on free market principles cannot be just. Rich world affluence would not be possible if wealth was not being transferred from poor countries. The only way out of the alarming global situation is via transition to some kind of Simpler Way, which is unlikely to be taken. Implications for bringing about such a transition will be indicated

The state of the Martian climate

60°N was +2.0°C, relative to the 1981–2010 average value (Fig. 5.1). This marks a new high for the record. The average annual surface air temperature (SAT) anomaly for 2016 for land stations north of starting in 1900, and is a significant increase over the previous highest value of +1.2°C, which was observed in 2007, 2011, and 2015. Average global annual temperatures also showed record values in 2015 and 2016. Currently, the Arctic is warming at more than twice the rate of lower latitudes

Development and validation of a targeted gene sequencing panel for application to disparate cancers

Next generation sequencing has revolutionised genomic studies of cancer, having facilitated the development of precision oncology treatments based on a tumour’s molecular profile. We aimed to develop a targeted gene sequencing panel for application to disparate cancer types with particular focus on tumours of the head and neck, plus test for utility in liquid biopsy. The final panel designed through Roche/Nimblegen combined 451 cancer-associated genes (2.01 Mb target region). 136 patient DNA samples were collected for performance and application testing. Panel sensitivity and precision were measured using well-characterised DNA controls (n = 47), and specificity by Sanger sequencing of the Aryl Hydrocarbon Receptor Interacting Protein (AIP) gene in 89 patients. Assessment of liquid biopsy application employed a pool of synthetic circulating tumour DNA (ctDNA). Library preparation and sequencing were conducted on Illumina-based platforms prior to analysis with our accredited (ISO15189) bioinformatics pipeline. We achieved a mean coverage of 395x, with sensitivity and specificity of >99% and precision of >97%. Liquid biopsy revealed detection to 1.25% variant allele frequency. Application to head and neck tumours/cancers resulted in detection of mutations aligned to published databases. In conclusion, we have developed an analytically-validated panel for application to cancers of disparate types with utility in liquid biopsy

The FANCM:p.Arg658* truncating variant is associated with risk of triple-negative breast cancer

Abstract: Breast cancer is a common disease partially caused by genetic risk factors. Germline pathogenic variants in DNA repair genes BRCA1, BRCA2, PALB2, ATM, and CHEK2 are associated with breast cancer risk. FANCM, which encodes for a DNA translocase, has been proposed as a breast cancer predisposition gene, with greater effects for the ER-negative and triple-negative breast cancer (TNBC) subtypes. We tested the three recurrent protein-truncating variants FANCM:p.Arg658*, p.Gln1701*, and p.Arg1931* for association with breast cancer risk in 67,112 cases, 53,766 controls, and 26,662 carriers of pathogenic variants of BRCA1 or BRCA2. These three variants were also studied functionally by measuring survival and chromosome fragility in FANCM−/− patient-derived immortalized fibroblasts treated with diepoxybutane or olaparib. We observed that FANCM:p.Arg658* was associated with increased risk of ER-negative disease and TNBC (OR = 2.44, P = 0.034 and OR = 3.79; P = 0.009, respectively). In a country-restricted analysis, we confirmed the associations detected for FANCM:p.Arg658* and found that also FANCM:p.Arg1931* was associated with ER-negative breast cancer risk (OR = 1.96; P = 0.006). The functional results indicated that all three variants were deleterious affecting cell survival and chromosome stability with FANCM:p.Arg658* causing more severe phenotypes. In conclusion, we confirmed that the two rare FANCM deleterious variants p.Arg658* and p.Arg1931* are risk factors for ER-negative and TNBC subtypes. Overall our data suggest that the effect of truncating variants on breast cancer risk may depend on their position in the gene. Cell sensitivity to olaparib exposure, identifies a possible therapeutic option to treat FANCM-associated tumors

The aim of this analysis was to identify genetic variants that are associated with urinary sex-hormone levels and breast cancer risk. Methods: We carried out a genome-wide association study of urinary oestrone-3-glucuronide and pregnanediol-3-glucuronide levels in 560 premenopausal women, with additional analysis of progesterone levels in 298 premenopausal women. To test for the association with breast cancer risk, we carried out follow-up genotyping in 90,916 cases and 89,893 controls from the Breast Cancer Association Consortium. All women were of European ancestry. Results: For pregnanediol-3-glucuronide, there were no genome-wide significant associations; for oestrone-3-glucuronide, we identified a single peak mapping to the CYP3A locus, annotated by rs45446698. The minor rs45446698-C allele was associated with lower oestrone-3-glucuronide (−49.2%, 95% CI −56.1% to −41.1%, P = 3.1 × 10–18); in follow-up analyses, rs45446698-C was also associated with lower progesterone (−26.7%, 95% CI −39.4% to −11.6%, P = 0.001) and reduced risk of oestrogen and progesterone receptor-positive breast cancer (OR = 0.86, 95% CI 0.82–0.91, P = 6.9 × 10–8). Conclusions: The CYP3A7*1C allele is associated with reduced risk of hormone receptor-positive breast cancer possibly mediated via an effect on the metabolism of endogenous sex hormones in premenopausal women

What if Stern is wrong?

This article challenges several of the core assumptions on which the report on the Economics of Climate Change by Nicholas Stern is based. These include Stern’s estimates of the potential for renewable energy and the capacity for carbon capture and storage in the combustion of fossil fuels for electricity

The implications of the global ecological predicament for economic theory and practice

Purpose – The purpose of this paper is to outline the implications of the global ecological predicament for economic theory and practice. Design/methodology/approach – Many current analyses of ecological, resource, economic, greenhouse, energy, etc. problems acknowledge the urgent need for significant changes. However, almost all assume that it will be possible to reform a society based on principles such as economic growth, affluent living standards, market systems, the profit motive and competitive, individualistic acquisitiveness, into a society that is sustainable and just. The first section of this paper sketches the grounds for concluding that this view is clearly mistaken. It shows that consumer-capitalist society cannot be fixed, i.e. that no amount of reforms leaving its core principles intact can make it into a society that is sustainable and just. The second section derives from this analysis some of the basic principles, which a satisfactory society must, therefore, have. Section 3 deals with the radical implications of these discussions for economic theory and practice. Findings – The paper shows that when the nature and magnitude of the global ecological situation is understood it is evident that a consumer-capitalist society cannot be made sustainable or just, and that the irremediable faults are largely due to conventional economic theory and practice. Social implications – The main sociological implication is that the coming era of scarcity will require radical restructuring of the economy and of economic theory. Originality/value – Previous critical economic literature has given little attention to the implications of the limits to growth literature focused on in this discussion.Consumerism, Economic theory, Society, Sustainable development

Social responsibility: the most important, and neglected, problem of all?

Purpose – To draw attention to an important but neglected topic, and provide an analysis that will help others to go further into key elements of the theme of social responsibility. Design/methodology/approach – A review of themes previously encountered in a diverse literature. Findings – It is argued that many powerful forces within capitalist-consumer society militate against social responsibility. In view of looming global justice and sustainability problems the lack of social responsibility points to gloomy prospects for humankind. Yet it is argued that the solution is theoretically simple and three essential themes for the discussion of positive action are considered. Practical implications – A number of important implications for education and social action are discussed. Originality/value – The topic seems to have been almost totally overlooked previously, although many works are tangentially related.Attitudes, Responsibilities, Social change, Social economics, Social interaction
