Coronavirus Disease 2019 in Solid Organ Transplant: A Multicenter Cohort Study.

Background: The coronavirus disease 2019 (COVID-19) pandemic has led to significant reductions in transplantation, motivated in part by concerns of disproportionately more severe disease among solid organ transplant (SOT) recipients. However, clinical features, outcomes, and predictors of mortality in SOT recipients are not well described.

Methods: We performed a multicenter cohort study of SOT recipients with laboratory-confirmed COVID-19.

Comparative assessment of the intrinsic sensitivity of crop species and wild plant species to plant protection products and their active substances and potential implications for the risk assessment: A literature review.

A comprehensive critical review was undertaken aiming to compare the intrinsic sensitivity of terrestrial plant species (crop species and noncrop wild species) with published literature and unpublished proprietary data generated for the registration of plant protection products (PPPs), and a database was compiled. Data were assessed to answer the question whether crops differ from noncrop plants in their intrinsic sensitivity to PPPs. Endpoints were assessed considering further potentially relevant parameters by means of different methods, including a quotient approach, in which overall crop endpoints were divided by matching wild species endpoints.

Raman Vibrational Shifts of Small Clusters of Hydrogen Isotopologues.

Raman vibrational shifts of small parahydrogen (pH2), orthodeuterium (oD2), and paratritium (pT2) clusters with respect to the free molecules are calculated by combining a first order perturbation theory approach with Langevin equation Path Integral Ground State (LePIGS) simulations [ J. Phys. Chem.

The onset of molecular condensation: hydrogen.

The very first steps of condensation as studied experimentally in the simplest molecular system (para-H(2)) are reported. The fast time-space evolution of the nascent clusters have been measured using state-of-the-art Raman spectroscopy implemented on cryogenic supersonic jets. The time-dependent onset of condensation is presented in a non-equilibrium pressure-temperature phase diagram.

Interatomic Coulombic decay following photoionization of the helium dimer: observation of vibrational structure.

Using synchrotron radiation we simultaneously ionize and excite one helium atom of a helium dimer (He2) in a shakeup process. The populated states of the dimer ion [i.e.

Blood group polymorphisms in the Canary Islands.

Human samples from the seven Canary Islands were studied for the following polymorphic red cell blood group systems: ABO, RH, MNSs, FY and P. In contrast to the intra-insular homogeneity found, inter-insular heterogeneity was observed for ABO, RH and FY. The observed blood group allelic systems were within the range of European populations, with some minor African contribution.

Human enzyme polymorphism in the Canary Islands. II. African influence.

The genetic polymorphism of eight red cell enzymes was examined in three samples from Gran Canaria and one from Equatorial Guinea. The presence of African genes in the Gran Canaria population showed an African admixture estimated to 6-9%. The genetic distance between Gran Canaria and Equatorial Guinea was 0.
