We investigated the interaction of the short PNA strand [acccca]-PNA with oligodeoxynucleotides containing one, two, or four tracts of TGGGGT units. Electrospray ionization mass spectrometry allowed exploring the wide variety of complex stoichiometries that were found to coexist in solution. In water, the PNA strand forms short heteroduplexes with the complementary DNA sequences, but higher-order structures are also found, with PNA(2n)*DNA(n) triplex units, culminating in precipitation at very low ionic strength. In the presence of ammonium acetate, there is a competition between PNA*DNA heteroduplex formation and DNA G-quadruplex formation. Heteroduplex formation is favored when the PNA + DNA mixture in ammonium acetate is heated and cooled at room temperature, but not if the PNA is added at room temperature to the pre-formed G-quadruplex. We also found that the short [acccca]-PNA strand binds to G-quadruplexes. (c) 2008 Wiley Periodicals, Inc. Biopolymers, 2008. [less ▲]

We show that a remarkable compatibility exists between the results of a potential model with constituent quarks and the 1/Nc expansion mass formula for strange and nonstrange baryon resonances. Such compatibility brings support to the basic assumptions of relativistic quark models and sheds light on the physical content of the model-independent large Nc mass formula. Good agreement between both approaches is also found for heavy baryons, made of one heavy and two light quarks, in the ground state band. [less ▲]

We used a candidate gene approach to identify a set of SNPs, located in a predicted regulatory region on chromosome 1q44 downstream of NLRP3 (previously known as CIAS1 and NALP3) that are associated with Crohn's disease. The associations were consistently replicated in four sample sets from individuals of European descent. In the combined analysis of all samples (710 father-mother-child trios, 239 cases and 107 controls), these SNPs were strongly associated with risk of Crohn's disease (P(combined) = 3.49 x 10(-9), odds ratio = 1.78, confidence interval = 1.47-2.16 for rs10733113), reaching a level consistent with the stringent significance thresholds imposed by whole-genome association studies. In addition, we observed significant associations between SNPs in the associated regions and NLRP3 expression and IL-1beta production. Mutations in NLRP3 are known to be responsible for three rare autoinflammatory disorders. These results suggest that the NLRP3 region is also implicated in the susceptibility of more common inflammatory diseases such as Crohn's disease. [less ▲]

In 1999, the large surface-rupturing earth- quakes of Izmit and Duzce completed a 60-year cycle that included a westward migration of nine consecutive large earthquake failures ([50 km surface rupture), which started with the 1939 Erzincan earthquake in eastern Turkey. In this study, we focused on seismic cycles and seismic risk predictability along the North Anatolian Fault (NAF). Toward the west end of the NAF (26°E–32°E, i.e. Bolu), large earthquake fre- quency is measured from either historic earthquake catalogs, or geologic records from isolated outcrops and marine sediment cores from the Marmara Sea. In comparison, the eastern part of the NAF zone (32°E– 42°E) is less well documented by palaeo-seismologic archives. Thus, the sediment records of lake basins located on the eastern NAF zone constitute a unique opportunity for testing a new palaeo-seismologic approach. To this end, we used a diverse array of complementary methods involving: (1) a 600-km transect of fault-related lakes, (2) sedimentologic observations on cores from six lakes, and (3) a comparison between records of catastrophic sediment transfers in lakes (i.e. radionuclide chronomarkers and erosion tracers) and historic earthquake reports. Our study indicates that lakes along the NAF are sensitive geologic recorders of large surface-rupturing earth- quakes (surface-wave magnitude (Ms) C 6.9); smaller intensities are not recorded. The most responsive lake systems exhibit increases in sediment accumulation by a factor of [40 for a [3-m strike-slip displacement (Ms C 7). However, based on results from the 1939 Erzincan earthquake (Ms = 7.8) chronostratigraphic marker, large surface-rupturing earthquakes are detected only by certain lake records and not by others. Matching multiple lake records along the NAF pro- vides information both on the location of a surface rupture of a paleo-earthquake as well as its magnitude. Finally, the shallow lake basins along the NAF could potentially document cycles of large seismic events for at least the late Holocene. [less ▲]

This study aimed at comparing the performance of filtered backprojection (FBP) and ordered subset expectation maximisation (OSEM) reconstruction algorithms available in several types of commercial SPECT software. Methods: Numerical simulations of SPECT acquisitions of two phantoms were used: the NEMA line used for the assessment of SPECT resolution and a phantom with uniform, hot and cold rod compartments. The investigated types of software were: General Electric Xeleris and Vision, Philips Jetstream, Segami Mirage, Siemens eSoft and Icon, and Sopha Medical Vision XT. For FBP, no filtering and filtering of the projections with either Butterworth (order 3 or 6) or Hanning filters at various cut-off frequencies were considered. For OSEM, the number of subsets was 1, 4, 8, or 16 and the number of iterations was chosen to obtain a product number of iterations times the number of subsets equal to 16, 32, 48 or 64. The line phantom enabled us to obtain the reconstructed central, radial and tangential full-widths at half-maximum. The uniform compartment of the second phantom delivered the mean reconstructed pixel values and the standard deviations from which the coefficients of variation were calculated. Hot and cold contrasts were obtained from its rod compartments. Results: For FBP, full-widths at half-maximum, mean pixel values, coefficients of variation and contrasts were almost software independent. The only exceptions were: smaller (0.5 mm) full-widths at half-maximum for Vision, larger mean pixel values for Vision and XT, and better contrasts for Vision and XT for some filtering conditions. For OSEM, full-widths at half-maximum differed between the different types of software from 0.1 to 2.5 mm but these were almost independent of the number of subsets or iterations. There was a high dependence of the mean pixel value on the type of software used and a moderate dependence of the coefficient of variation. The contrasts were almost software independent. Mean pixel value varied greatly with the number of iterations for Mirage and Vision, and the coefficient of variation increased with the number of iterations for all types of software. The mean pixel value, the coefficient of variation and the contrasts were almost constant for a fixed product number of iterations times the number of subsets, whatever the number of subsets or iterations. Conclusion: Most of the types of software were equivalent for FBP or OSEM reconstruction. However, a few differences were observed for some types of software and should be considered when using them.

Classical risk assessment paradigms no longer suffice to deal with complex, uncertain and ambiguous risks. Therefore, new approaches to prevent, control, communicate, and deal with the causes of these risks and with public anxieties about risks are necessary. In phase 1 we analyzed the available concepts to integrate risk and economical assessment with social aspects in one framework, and discussed the relevant criteria that need to be considered in order to develop a final risk assessment framework. Furthermore, still in phase 1, empirical work was performed in the form of case studies to analyze and define a framework, or to select criteria. We are in the process of reviewing, selecting, and testing tools and instruments that can be used in this appraisal framework, to go from concepts to practice. To grasp the full complexity of controversial, uncertain and immature risks, to cope with different values and views, and to develop a good communication we consider the appraisal framework as a procedural decision making process. It requires a more participative approach as the legal rational approach does not deliver adequate public management tools for handling these issues. We propose a sequential model, going through a series of steps, that can be used both in cases of strategic planning and management, and in the management of local projects usually related to siting conflicts. In each phase of the model integrated assessment tools and methods can be applied up to the point where consensus or a clear representation of different values and views (ideal in very uncertain and ambiguous problems), or an optimal balance between different criteria (in more simple cases) is achieved. All together our Appraisal Framework [is shaped] as a process, structuring and supporting the decision-making process. • To promote and organize a mutual learning of all actors entering into the policy cycle spiralling up through the different phases. • In the context of local siting conflicts, local contamination issues and urban planning topics (all with very close relationships with individuals), including regional, global E&H issues (food, climate, air, transport…) It’s a policy cycle, focused around a certain problem, organised to formulate and evaluate policy options, with stakeholders involved at different phases and steps of the process. Here the AF is structured as a learning network composed of all the players entering into the decision-making process at different stages. The quality of the decision making process can be appreciated either on the basis of its outcomes or on the process itself. Our framing falls under the latter. It also rests on the procedural equity feeling and its impact on the acceptability of the effects of the decision (Joss S. and Brownlea A., 1999). Such an approach opens the way to a greater legitimacy of decisions whose substantive effects or outcomes are essentially dubious – a fortiori in the context of the precaution. It encourages a reflection on the manner of combining the opening of the decision-making process through participative methods with others meta-tools such as strategic management, integrated and comparative approach of the risk, or the evaluative method. These meta-tools structure the participative step, giving it objectives, precise questions and ad hoc means. It contributes to the technical quality of the decision and to its social acceptability, particularly when it is the product of a decision-making process which the actors consider precautionary and adapted to the context of great scientific uncertainty.

This article aims to show that in the socialist tradition, alongside Marx, there is a position as materialist – or perhaps more so – that it would be valuable to combine with his powerful critique of capitalism. This perspective is that of Proudhon. According to the author, there are possibilities of emancipation through work that are not exclusively conditioned by the “Great Day”, typical of Marxist rhetoric, and which emerge here and now thanks to this perspective. Of course Prouhon’s work is philosophically and economically less powerful than that of Marx. However, his work is interesting in that he enables us to see in the “working” man something other than a stubborn animal, de-subjectivized by capitalism and existing only as a means of production. This is why, if indeed this is anthropology, it may be called positive anthropology. By continuously and almost exclusively favoring the notion of alienation, Marx runs the risk of allowing a purely negative anthropology to emerge in his work. This even today feeds the critical theory of certain authors who see in the modern man an alienated and brainless consumer who must be stripped of his illusions. [less ▲]

The objective of the study assess the relationship between bone mineral density (BMD) loss over time and fracture incidence in postmenopausal women. This is a posthoc analysis that includes women from the placebo group of two large randomized controlled trials having assessed the efficacy of a new anti-osteoporotic drug. BMD was assessed every 6 months during 3 years at the lumbar spine, the femoral neck and the total proximal femur. Vertebral fractures were assessed using a semiquantitative method. Hip fractures were based on written documentation. All patients received calcium and vitamin D. In the present study that included 1,775 patients (with complete data at baseline and after 3 years), the logistic regression analysis, adjusted for covariates, showed that 3-year change in lumbar BMD was not statistically associated with the new vertebral fractures after 3 years. However, femoral neck and total proximal femur BMD changes was statistically correlated with the incidence of new vertebral fractures (P < 0.001). When considering change in BMD after the first year of follow-up, a decrease in total proximal femur BMD was statistically associated with an increase in the incidence of new vertebral fractures during the last 2 years of follow-up (P = 0.048). The 3-year change in femoral neck and total proximal BMD was statistically correlated with the incidence of hip and fragility fracture after 3 years (all P < 0.001). In this elderly osteoporotic population receiving calcium and vitamin D, a decrease in hip BMD after 1 or 3 year of follow-up, is associated with an increased risk of fracture incidence. However, spine BMD changes do not influence vertebral fracture incidence. [less ▲]
