When the 1993 Kirkenes Declaration was ratified, the governments of Russia, Finland, Sweden, and Norway “expressed their conviction that expanded co-operation in the Barents Euro-Arctic Region (BEAR) will contribute substantially to stability and progress in the area and in Europe as a whole.” (Kirkenes Declaration 1993). Over 20 years later, and as we move forward, this goal is even more important ...

In birds with extrapair mating, older males usually have higher fertilization success than younger males. Two hypotheses can potentially explain this pattern: 1) females prefer older, and often more ornamented males, or 2) older males invest more in reproduction and fertility than younger males. Here we studied factors associated with age-related male fertilization success in a population of barn ...

This study evaluated the performance of the MBT STAR-Carba kit (Bruker Daltonics), to detect carbapenemase producing Enterobacteriaceae, Pseudomonas aeruginosa and Acinetobacter spp. in comparison with the RAPIDEC® CARBA NP test (BioMerieux). MBT STAR-Carba allowed the detection of carbapenemases in Enterobacteriaceae and P. aeruginosa.

<p>This thesis addressed phenotypic and genetic variation in seasonal time keeping mechanisms of the tundra vole (<i>Microtus oeconomus</i>) and the common vole (<i>Microtus arvalis</i>). Voles (<i>Microtus</i>) are short-lived, non-hibernating and seasonally breeding rodents. The genus has rapidly evolved (< 2 million years) into one of the most speciose mammalian genera (Sitnikova et al. 2007; ...

The photophysical properties of nitridoosmium(VI) corroles have been investigated. The complexes exhibit room temperature NIR phosphorescence (l_max 779–795 nm). Long decay times (110–150 ms in solution and 136–183 ms in polystyrene) are responsible for efficient quenching of the emission by oxygen. All the complexes act as efficient sensitizers of singlet oxygen (quantum yields of ...

The EMASAR study is the first study to describe the body burden of OCs in Argentinian women after delivery. In total, 698 maternal serum samples from Salta (n ¼ 498) and Ushuaia (n ¼ 200) were collected in 2011–2012 and analyzed for a total of 7 polychlorinated biphenyls (PCBs) and 12 pesticide-related compounds. Only 11 of the compounds had detection rates above 60% in one or both places. Compared ...

In this Frontiers article, we highlight how state-of-the-art density functional theory calculations can contribute to the field of homogeneous photoredox catalysis. We discuss challenges in the fields and potential solutions to be found at the interface between theory and experiment. The exciting opportunities and insights that can arise through such an interdisciplinary approach are highlighted.

A novel non-centrosymmetric π-expanded diketopyrrolopyrrole was designed and synthesized. Strategic placement of tert-butyl groups at the periphery of a diketopyrrolopyrrole allowed us to selectively fuse one moiety via tandem Friedel–Crafts-dehydration reactions, resulting in a non-centrosymmetric dye. The structure of the dye was confirmed by X-ray crystallography, revealing that it contains a ...

Background: Violence has important health effects. The results of exposure to physical violence include, but may not be limited to, death from suicide and homicide. The connection between the experience of assault and risk of death from causes other than homicide and suicide has rarely been examined.<p> <p>Methods: We analysed data from the first Izhevsk Family Study (IFS-1), a populationbased ...

Background and Aims: Low-dose naltrexone [LDN] is a controversial off-label treatment used by many Crohn’s disease [CD] and ulcerative colitis [UC] patients. A small number of preliminary studies indicate that LDN might be beneficial in CD, but evidence is too scarce to demonstrate efficacy. We sought to examine whether initiation of LDN therapy by patients with inflammatory bowel disease [IBD] ...
