Common variants in the ATM, BRCA1, BRCA2, CHEK2 and TP53 cancer susceptibility genes are unlikely to increase breast cancer risk
Caroline Baynes, Catherine S Healey, Karen A Pooley, Serena Scollen, Robert N Luben, Deborah J Thompson, Paul DP Pharoah, Douglas F Easton, Bruce AJ Ponder, Alison M Dunning, the SEARCH breast cancer study
Breast Cancer Research , 2007, DOI: 10.1186/bcr1669
Abstract: We have attempted a comprehensive, single nucleotide polymorphism (SNP)- and haplotype-tagging association study on each of these five genes in up to 4,474 breast cancer cases from the British, East Anglian SEARCH study and 4,560 controls from the EPIC-Norfolk study, using a two-stage study design. Nine tag SNPs were genotyped in ATM, together with five in BRCA1, sixteen in BRCA2, ten in CHEK2 and five in TP53, with the aim of tagging all other known, common variants. SNPs generating the common amino acid substitutions were specifically forced into the tagging set for each gene.No significant breast cancer associations were detected with any individual or combination of tag SNPs.It is unlikely that there are any other common variants in these genes conferring measurably increased risks of breast cancer in our study population.Four of the genes which lie in the DNA damage-recognition and repair pathway, ATM, BRCA1, BRCA2 and TP53, have mutations that are recognised to increase breast cancer susceptibility with moderate to high penetrance. Such mutations are very rare, and most probably of recent origin. A fifth gene, CHEK2, in the same pathway, has a deletion (1100delC) that reaches polymorphic frequencies (>0.01) in some European countries and doubles the risk of breast cancer in female carriers [1]. Together these mutations account for only a small proportion (2% to 5%) of all breast cancer incidences [2,3]. Breast cancer is, however, a common disease and genetic epidemiological data suggest that there is a low-penetrance genetic contribution to most cases [4,5]. It is likely that at least a part of breast cancer aetiology will fit the common disease-common variant hypothesis, which states that patients with a common, complex disease are likely to share some common, low-penetrance alleles that increase their susceptibility to that disease. This raises the question of whether such common, polymorphic susceptibility alleles exist within these five genes in addition t
Nonlocal appearance of a macroscopic angular momentum
G. S. Paraoanu,R. Healey
Physics , 2012, DOI: 10.1007/s10773-011-1056-8
Abstract: We discuss a type of measurement in which a macroscopically large angular momentum (spin) is "created" nonlocally by the measurement of just a few atoms from a double Fock state. This procedure apparently leads to a blatant nonconservation of a macroscopic variable - the local angular momentum. We argue that while this gedankenexperiment provides a striking illustration of several counter-intuitive features of quantum mechanics, it does not imply a non-local violation of the conservation of angular momentum.

The IDND facilitates effective and sustainable interactions among a local and diverse group of dementia researchers, clinical providers, and community advocates interested in improving care for dementia patients in Indianapolis, Indiana.Results: The IDND was established in February 2006 and now includes more than 250 members from more than 30 local (central Indiana) organizations representing 20 disciplines. The network uses two types of communication to connect its members. The first is a 2-hour face-to-face bimonthly meeting open to all members. The second is a web-based resource center (http://www.indydiscoverynetwork.org). To date, the network has: (1) accomplished the development of a network website with an annual average of 12,711 hits per day; (2) produced clinical tools such as the Healthy Aging Brain Care Monitor and the Anticholinergic Cognitive Burden Scale; (3) translated and implemented the collaborative dementia care model into two local health care systems; (4) created web-based tracking software, the Enhanced Medical Record for Aging Brain Care (eMR-ABC), to support care coordination for patients with dementia; (5) received more than USD$24 million in funding for members for dementia-related research studies; and (6) adopted a new group-based problem-solving process call

Fostering Technologies for Sustainability: Learning from the Case of Wind Power in Australia
Healey, Gerard
Australian Journal of Emerging Technologies and Society , 2004,
Abstract: Sustainable energy systems are widely seen as a desirable goal, but what constitutes such systems and how to make the transition from current practice to sustainable practice are more contested. Developed nations are locked-in to fossil fuel use, with a myriad of economic, technical, institutional and social obstacles discouraging change. Such obstacles are currently being faced by wind power proponents. The latter are promoting wind power in Australia because they believe it has a role in a sustainable energy system. The paper proposes that society can learn about the introduction of sustainable technologies from the wind power case and suggests a body of theory and an analytical method for this purpose. The methodological argument is supported by the preliminary results of an ongoing empirical study. The paper concludes with a reflection on the theory and method and an outline of future research.
Quantum Theory: a Pragmatist Approach
Richard Healey
Physics , 2010,
Abstract: While its applications have made quantum theory arguably the most successful theory in physics, its interpretation continues to be the subject of lively debate within the community of physicists and philosophers concerned with conceptual foundations. This situation poses a problem for a pragmatist for whom meaning derives from use. While disputes about how to use quantum theory have arisen from time to time, they have typically been quickly resolved, and consensus reached, within the relevant scientific sub-community. Yet rival accounts of the meaning of quantum theory continue to proliferate . In this article I offer a diagnosis of this situation and outline a pragmatist solution to the problem it poses, leaving further details for subsequent articles.
Reduction and Emergence in Bose-Einstein Condensates
Richard Healey
Physics , 2009, DOI: 10.1007/s10701-010-9481-8
Abstract: A closer look at some proposed Gedanken-experiments on BECs promises to shed light on several aspects of reduction and emergence in physics. These include the relations between classical descriptions and different quantum treatments of macroscopic systems, and the emergence of new properties and even new objects as a result of spontaneous symmetry breaking.
