    Mediating the GM Foods Debate: Lessons from the Enduring Conflict Framework

    Get PDF
    Critics of the commercialization of Genetically Modified (GM) foods in Canada and the United States oppose the economic and political forces that create and approve the technology: the industry that develops it and the governments that approve its use. The conventional narrative pits the concerned public, labeled anti-GM, against the pro-GM interests of industry supported by business-friendly governments. Based on this binary view of the interests and motivations of stakeholders, conflict betwee

    New infant cranium from the African Miocene sheds light on ape evolution

    The evolutionary history of extant hominoids (humans and apes) remains poorly understood. The African fossil record during the crucial time period, the Miocene epoch, largely comprises isolated jaws and teeth, and little is known about ape cranial evolution. Here we report on the, to our knowledge, most complete fossil ape cranium yet described, recovered from the 13 million-year-old Middle Miocene site of Napudet, Kenya. The infant specimen, KNM-NP 59050, is assigned to a new species of Nyanzapithecus on the basis of its unerupted permanent teeth, visualized by synchrotron imaging. Its ear canal has a fully ossified tubular ectotympanic, a derived feature linking the species with crown catarrhines. Although it resembles some hylobatids in aspects of its morphology and dental development, it possesses no definitive hylobatid synapomorphies. The combined evidence suggests that nyanzapithecines were stem hominoids close to the origin of extant apes, and that hylobatid-like facial features evolved multiple times during catarrhine evolution

    ISARIC-COVID-19 dataset: A Prospective, Standardized, Global Dataset of Patients Hospitalized with COVID-19

    No full text
    The International Severe Acute Respiratory and Emerging Infection Consortium (ISARIC) COVID-19 dataset is one of the largest international databases of prospectively collected clinical data on people hospitalized with COVID-19. This dataset was compiled during the COVID-19 pandemic by a network of hospitals that collect data using the ISARIC-World Health Organization Clinical Characterization Protocol and data tools. The database includes data from more than 705,000 patients, collected in more than 60 countries and 1,500 centres worldwide. Patient data are available from acute hospital admissions with COVID-19 and outpatient follow-ups. The data include signs and symptoms, pre-existing comorbidities, vital signs, chronic and acute treatments, complications, dates of hospitalization and discharge, mortality, viral strains, vaccination status, and other data. Here, we present the dataset characteristics, explain its architecture and how to gain access, and provide tools to facilitate its use

    Λc+\Lambda^+_c production in pppp and in pp-Pb collisions at sNN\sqrt {s_{NN}}=5.02 TeV

    International audienceThe production cross section of prompt Λc+\mathrm{\Lambda_{c}^{+}} charm baryons was measured with the ALICE detector at the LHC at midrapidity in proton-proton (pp) and proton-lead (p-Pb) collisions at a centre-of-mass energy per nucleon pair of sNN=5.02\sqrt{s_\mathrm{NN}} = 5.02 TeV. The Λc+\mathrm{\Lambda_{c}^{+}} and Λc\rm {\overline{\Lambda}{}_c^-} baryons were reconstructed in the hadronic decay channels Λc+pKπ+\rm \Lambda_{c}^{+} \rightarrow p K^{-}\pi^{+} and Λc+pKS0\rm \Lambda_{c}^{+}\to p K^{0}_{S} and respective charge conjugates. The measured differential cross sections as a function of transverse momentum (pTp_{\rm T}) and the pTp_{\rm T}-integrated Λc+\mathrm{\Lambda_{c}^{+}} production cross section in pp and in p-Pb collisions are presented. The Λc+\mathrm{\Lambda_{c}^{+}} nuclear modification factor (RpPbR_\mathrm{pPb}), calculated from the cross sections in pp and in p-Pb collisions, is presented and compared with the RpPbR_\mathrm{pPb} of D mesons. The Λc+/D0\mathrm {\Lambda_{c}^{+}}/\mathrm {D^0} ratio is also presented and compared with the light-flavour baryon-to-meson ratios p/π/\pi and Λ/KS0\Lambda /\mathrm {K^0_S}, and measurements from other LHC experiments. The results are compared to predictions from model calculations and Monte Carlo event generators

    Implementation of Recommendations on the Use of Corticosteroids in Severe COVID-19

    Importance: Research diversity and representativeness are paramount in building trust, generating valid biomedical knowledge, and possibly in implementing clinical guidelines. Objectives: To compare variations over time and across World Health Organization (WHO) geographic regions of corticosteroid use for treatment of severe COVID-19; secondary objectives were to evaluate the association between the timing of publication of the RECOVERY (Randomised Evaluation of COVID-19 Therapy) trial (June 2020) and the WHO guidelines for corticosteroids (September 2020) and the temporal trends observed in corticosteroid use by region and to describe the geographic distribution of the recruitment in clinical trials that informed the WHO recommendation. Design, setting, and participants: This prospective cohort study of 434 851 patients was conducted between January 31, 2020, and September 2, 2022, in 63 countries worldwide. The data were collected under the auspices of the International Severe Acute Respiratory and Emerging Infections Consortium (ISARIC)-WHO Clinical Characterisation Protocol for Severe Emerging Infections. Analyses were restricted to patients hospitalized for severe COVID-19 (a subset of the ISARIC data set). Exposure: Corticosteroid use as reported to the ISARIC-WHO Clinical Characterisation Protocol for Severe Emerging Infections. Main outcomes and measures: Number and percentage of patients hospitalized with severe COVID-19 who received corticosteroids by time period and by WHO geographic region. Results: Among 434 851 patients with confirmed severe or critical COVID-19 for whom receipt of corticosteroids could be ascertained (median [IQR] age, 61.0 [48.0-74.0] years; 53.0% male), 174 307 (40.1%) received corticosteroids during the study period. Of the participants in clinical trials that informed the guideline, 91.6% were recruited from the United Kingdom. In all regions, corticosteroid use for severe COVID-19 increased, but this increase corresponded to the timing of the RECOVERY trial (time-interruption coefficient 1.0 [95% CI, 0.9-1.2]) and WHO guideline (time-interruption coefficient 1.9 [95% CI, 1.7-2.0]) publications only in Europe. At the end of the study period, corticosteroid use for treatment of severe COVID-19 was highest in the Americas (5421 of 6095 [88.9%]; 95% CI, 87.7-90.2) and lowest in Africa (31 588 of 185 191 [17.1%]; 95% CI, 16.8-17.3). Conclusions and relevance: The results of this cohort study showed that implementation of the guidelines for use of corticosteroids in the treatment of severe COVID-19 varied geographically. Uptake of corticosteroid treatment was lower in regions with limited clinical trial involvement. Improving research diversity and representativeness may facilitate timely knowledge uptake and guideline implementation
