The "anticonvulsant face," with a short nose, broad nasal bridge, epicanthal folds, and wide mouth, was described in the 1970s in children who had been exposed during pregnancy to the anticonvulsant drugs phenytoin and phenobarbital. The laser light scan makes it possible to establish three-dimensional positions of physical features and to determine more objectively the changes in the size and shape of the affected soft tissues of the faces of children exposed to these anticonvulsant drugs during pregnancy.Thirteen individuals, exposed throughout pregnancy to phenytoin as either monotherapy or polytherapy, were identified in a previous analysis as having significant changes in their craniofacial features based on measurements of cephalometric radiographs. Those changes were associated with midface hypoplasia and a short nose, features of the "anticonvulsant face." The soft tissues of their faces have been evaluated with laser light scans.The notable changes in soft tissues identified by laser light scans were a wide philtrum (cph-cph), narrow mouth (ch-ch), short nasal bridge (n-prn), shortened nose height (n-sn), and flattened orbits (orbital protrusion index).This analysis of the facial features of phenytoin-exposed individuals, selected because of changes in their craniofacial bony structures, showed that there were several significant changes, two of which, widening of the philtrum and a small mouth, have not been described previously as part of this phenotype.

International audience; In this study, high resolution coupled and uncoupled regional atmospheric (WRF) and oceanic (ROMS) simulations for the Californian Current System are used to assess how air-sea interactions affect upwelling, atmosphere variability and primary production at different time scale. The simulations are done over the 1995-2009 time period including the 1997-1998 El Niño event. As a first step, the CORE bulk formulae has been implemented and tested in uncoupled ROMS simulations using different atmospheric products. Main results show its ability in estimating realistically both momentum and turbulent heat fluxes. However, these first simulations highlight that, due to a poor representation of both solar radiations and coastal surface wind, global product are not reliable to force such oceanic simulations. We then show that our uncoupled and coupled longterm simulations are realistic and contain a wide range of scales from daily to interannual. By coupling Ocean to Atmosphere, the mixed-layer heat balance is impacted through a combination of different solar radiations, turbulent heat fluxes and vertical mixing. The upwelling intensity and structure are also impacted leading to a different biogeochemical response.

The conversion of dissolved nutrients and carbon to organic matter by phytoplankton in the surface ocean, and its downward transport by sinking particles, produces a “biological pump” that reduces the concentration of atmospheric CO2. Global rates of organic matter export are a poor indicator of biological carbon storage however, because organic matter gets distributed across water masses with diverse pathways and timescales of return to the surface. Here we show that organic matter export and carbon storage can be related through a sequestration efficiency, which measures how long regenerated nutrients and carbon will be stored in the interior ocean before being returned to the surface. For the first time, we derive global maps of the sequestration efficiency of the biological pump at different residence time horizons. These maps reveal how regional patterns of organic matter export contribute to the biological pump, and how the biological pump responds to changes in biological productivity driven by climate change.

Recurrent microdeletions and microduplications of a 600-kb genomic region of chromosome 16p11.2 have been implicated in childhood-onset developmental disorders. We report the association of 16p11.2 microduplications with schizophrenia in two large cohorts. The microduplication was detected in 12/1,906 (0.63%) cases and 1/3,971 (0.03%) controls (P = 1.2 x 10(-5), OR = 25.8) from the initial cohort, and in 9/2,645 (0.34%) cases and 1/2,420 (0.04%) controls (P = 0.022, OR = 8.3) of the replication cohort. The 16p11.2 microduplication was associated with a 14.5-fold increased risk of schizophrenia (95% CI (3.3, 62)) in the combined sample. A meta-analysis of datasets for multiple psychiatric disorders showed a significant association of the microduplication with schizophrenia (P = 4.8 x 10(-7)), bipolar disorder (P = 0.017) and autism (P = 1.9 x 10(-7)). In contrast, the reciprocal microdeletion was associated only with autism and developmental disorders (P = 2.3 x 10(-13)). Head circumference was larger in patients with the microdeletion than in patients with the microduplication (P = 0.0007).

Culture studies of denitrifying bacteria predict that denitrification will generate equivalent gradients in the delta N-15 and delta O-18 of deep ocean nitrate. A depth profile of nitrate isotopes from the Hawaii Ocean Time-series Station ALOHA shows less of an increase in delta O-18 than in delta N-15 as one ascends from abyssal waters into the denitrification-impacted mid-depth waters. A box model of the ocean nitrate N and O isotopes indicates that this is the effect of the low latitude nitrate assimilation/regeneration cycle: organic N sinking out of the surface spreads the high-delta N-15 signal of pelagic denitrification into waters well below and beyond the suboxic zone, whereas the nitrate delta O-18 signal of denitrification can only be transmitted by circulation in the interior.
