Blood pressure is a heritable trait influenced by several biological pathways and responsive to environmental stimuli. Over one billion people worldwide have hypertension (≥140 mm Hg systolic blood pressure or  ≥90 mm Hg diastolic blood pressure). Even small increments in blood pressure are associated with an increased risk of cardiovascular events. This genome-wide association study of systolic and diastolic blood pressure, which used a multi-stage design in 200,000 individuals of European descent, identified sixteen novel loci: six of these loci contain genes previously known or suspected to regulate blood pressure (GUCY1A3-GUCY1B3, NPR3-C5orf23, ADM, FURIN-FES, GOSR2, GNAS-EDN3); the other ten provide new clues to blood pressure physiology. A genetic risk score based on 29 genome-wide significant variants was associated with hypertension, left ventricular wall thickness, stroke and coronary artery disease, but not kidney disease or kidney function. We also observed associations with blood pressure in East Asian, South Asian and African ancestry individuals. Our findings provide new insights into the genetics and biology of blood pressure, and suggest potential novel therapeutic pathways for cardiovascular disease prevention.

The critical process parameter for mineral separation is the degree of mineral liberation achieved by comminution. The degree of liberation provides an upper limit of efficiency for any physical separation process. The standard approach to measuring mineral liberation uses mineralogical analysis based two-dimensional sections of particles which may be acquired using a scanning electron microscope and back-scatter electron analysis or from an analysis of an image acquired using an optical microscope. Over the last 100 years, mathematical techniques have been developed to use this two dimensional information to infer three-dimensional information about the particles. For mineral processing, a particle that contains more than one mineral (a composite particle) may appear to be liberated (contain only one mineral) when analysed using only its revealed particle section. The mathematical techniques used to interpret three-dimensional information belong, to a branch of mathematics called stereology. However methods to obtain the full mineral liberation distribution of particles from particle sections are relatively new. To verify these adjustment methods, we require an experimental method which can accurately measure both sectional and three dimensional properties. Micro Cone Beam Tomography provides such a method for suitable particles and hence, provides a way to validate methods used to convert two-dimensional measurements to three dimensional estimates. For this study ore particles from a well-characterised sample were subjected to conventional mineralogical analysis (using particle sections) to estimate three-dimensional properties of the particles. A subset of these particles was analysed using a micro-cone beam tomograph. This paper presents a comparison of the three-dimensional properties predicted from measured two-dimensional sections with the measured three-dimensional properties.

À la fin du 19e siècle, lIran commence à se transformer radicalement. Ce changement est le résultat d’un processus de métamorphose socioculturelle, avec le désir d’effacer les méthodes du passé et de recommencer ; une ambition de faire un renouvellement fondamental dans la société, en bénéficiant des grandes idées progressistes de l'Occident moderne. Cette volonté s’est renforcée à la suite des premières visites en Europe d’étudiants et de Nassereddin Shah, le roi de l'Iran, dans les années 1870. Dans ce contexte, les Iraniens et leurs gouvernants, considérant leurs infériorités politico-économiques, ont décidé de remplacer les frustrations internationales par des idées nationalistes et une propagande de suprématie raciale ou religieuse, notamment concertant « l'identité culturelle ». Suivant ces tentatives pour réformer les infrastructures sociopolitiques de l'Iran, tous les domaines culturels du pays, incluant larchitecture, ont été modifiés, selon les idéologies des dirigeants de lIran pendant trois périodes historiques du pays : l'époque Qadjar (dès le règne de Nassereddin Shah en 1848), l'époque Pahlavi (1925-1979) et l'époque Post-révolution islamique (1979- jusqu'à présent). L'idée générale de notre mémoire est d'étudier le processus de modernisation de l'architecture de l'Iran, de même que les influences majeures de tous ces changements, concrétisés par des fusions éclectiques et des idées pluralistes – souvent basées sur la politique. De l, en usant des approches de lhistoire sociale et culturelle de lart, nous analysons des exemples de monuments de l'architecture publique de l'Iran depuis l'entrée de l'Iran dans la modernité, pour chacune des trois périodes mentionnées. Cela, afin de comprendre si les architectes iraniens ont trouvé de nouvelles conceptions pour opérer un déploiement créatif des principes traditionnels et pour trouver de nouvelles orientations dans le processus général de leur évolution architecturale. Autrement dit, nous cherchons à savoir si l'architecture iranienne, avec tous les changements stylistiques dans le processus de conceptualisation, a pu trouver - depuis l'intervention de la modernité occidentale et de l'architecture moderne - son propre langage de la modernité en architecture.

Homozygosity has long been associated with rare, often devastating, Mendelian disorders1, and Darwin was one of the first to recognize that inbreeding reduces evolutionary fitness2. However, the effect of the more distant parental relatedness that is common in modern human populations is less well understood. Genomic data now allow us to investigate the effects of homozygosity on traits of public health importance by observing contiguous homozygous segments (runs of homozygosity), which are inferred to be homozygous along their complete length. Given the low levels of genome-wide homozygosity prevalent in most human populations, information is required on very large numbers of people to provide sufficient power3, 4. Here we use runs of homozygosity to study 16 health-related quantitative traits in 354,224 individuals from 102 cohorts, and find statistically significant associations between summed runs of homozygosity and four complex traits: height, forced expiratory lung volume in one second, general cognitive ability and educational attainment (P < 1 × 10−300, 2.1 × 10−6, 2.5 × 10−10 and 1.8 × 10−10, respectively). In each case, increased homozygosity was associated with decreased trait value, equivalent to the offspring of first cousins being 1.2 cm shorter and having 10 months’ less education. Similar effect sizes were found across four continental groups and populations with different degrees of genome-wide homozygosity, providing evidence that homozygosity, rather than confounding, directly contributes to phenotypic variance. Contrary to earlier reports in substantially smaller samples5, 6, no evidence was seen of an influence of genome-wide homozygosity on blood pressure and low density lipoprotein cholesterol, or ten other cardio-metabolic traits. Since directional dominance is predicted for traits under directional evolutionary selection7, this study provides evidence that increased stature and cognitive function have been positively selected in human evolution, whereas many important risk factors for late-onset complex diseases may not have been.
