Genetic unexceptionalism: Clinician accounts of genetic testing for familial hypercholesterolaemia
This paper considers the implications of genetic testing in the case of familial hypercholesterolaemia, drawing on twenty semi-structured interviews with general practitioners (family doctors in primary care), nurses and specialists in hospital clinics (secondary care) in the UK. Though these professionals appear aware of and interested in the genetic component of the condition, and DNA testing is underway in at least some centres, their accounts suggest that the genetic test is not having a major impact on clinical work. Instead we find that professionals report that they generally rely on other information when making a diagnosis, especially cholesterol levels understood as a key risk factor, while the results of DNA tests, if used, come late in a much longer series of clinical investigations, judgements and inter- ventions. In addition to elaborating professional views of genetic testing, the research provides a way of understanding other studies that describe lay people as not necessarily privileging genetic explanations of familial hypercholesterolaemia
Electron Attachment in Ice−HCl Clusters: An ab Initio Study
Experimental work has shown that small amounts of HCl strongly enhance electron capture in ice films. The
purpose of the present study was to investigate the effect of adsorbed HCl on the interaction of electrons with
small clusters of water. Studies were made with clusters of 6 and 12 water molecules with various geometries
both with and without one HCl attached. A number of distinct HCl coordination motifs were examined. All
of the neutral structures with HCl exhibited zero thresholds for electron attachment and formed dipole bound
anionic states (DBS). The relaxation processes for these “initial DBS” depended on the number of H2O (n)
and on the number and type of H-bonds to the HCl (x). The initial DBS of systems with only O−H···Cl
H-binding underwent dissociative electron attachment (DEA), forming H atoms. Relaxation for systems with
ClH···OH2 bonds was more complex. For the two layer n = 12 systems with x = 2 or 3 the HCl proton
moved to the nearest oxygen to form H3O+. Then rearrangement of the proton network occurred, and the Cl-
became solvated by three HO−H···Cl- bonds. The presence of Cl- and H3O+ increases the dipole moment
and the electron binding energy (EBE) of the network. Further stabilization is achieved by decay into deeper
DBS electron traps and/or by reaction of the excess electron with H3O+ to form H• atoms. The HCl(H2O)6
clusters with a single Cl−H···OH2 bond behaved differently. They increased their stability by becoming
more linear. This raised the dipole moment and the EBE therefore increased, reducing the total energy. None
of these species showed any signs of increasing the number of H-bonds to Cl. The implication of these
observations for the interpretation of the results of the experiments with 0.2 monolayer of HCl on 5 monolayer
of H2O at 20 K, and on the possible role of cosmic ray-induced ionization in polar stratospheric clouds in
ozone depletion is discussed
