  • The legacy of biogeographic history on the composition and structure of Andean forests. [Journal Article]
    Ecology. 2020 Jul 06 [Online ahead of print]González-Caro S, Duque Á, … Yepes A
  • The biogeographic origin of species may help to explain differences in average tree height and aboveground biomass (AGB) of tropical mountain forests. After the Andean uplift, small-statured trees should have been amongst the initial colonizers of the highlands (new cold environment) from the lowland tropics since these species are pre-adapted to cold conditions with narrow vessels that are relat…
  • Safety of Tofacitinib in a Real-World Cohort of Patients With Ulcerative Colitis. [Journal Article]
    Clin Gastroenterol Hepatol. 2020 Jul 03 [Online ahead of print]Deepak P, Alayo QA, … Yarur A
  • CONCLUSIONS: Real-world safety signals for tofacitinib are similar to those for clinical trials, with AEs reported from almost 16% of patients. HZ infection and VTE occurred in patients receiving 10 mg tofacitinib twice per day. These results support dose de-escalation after induction therapy, to reduce the risk of AEs.
  • Topologically Nontrivial Phase-Change Compound GeSb2Te4. [Journal Article]
    ACS Nano. 2020 Jul 06 [Online ahead of print]Nurmamat M, Okamoto K, … Kimura A
  • Chalcogenide phase-change materials show strikingly contrasting optical and electrical properties, which has led to their extensive implementation in various memory devices. By performing spin-, time-, and angle-resolved photoemission spectroscopy combined with the first-principles calculation, we report the experimental results that the crystalline phase of GeSb2Te4 is topologically nontrivial i…
  • Modelling climate change impacts on maize yields under low nitrogen input conditions in sub-Saharan Africa. [Journal Article]
    Glob Chang Biol. 2020 Jul 06 [Online ahead of print]Falconnier GN, Corbeels M, … Webber H
  • Smallholder farmers in sub-Saharan Africa (SSA) currently grow rainfed maize with limited inputs including fertilizer. Climate change may exacerbate current production constraints. Crop models can help quantify the potential impact of climate change on maize yields, but a comprehensive multi-model assessment of simulation accuracy and uncertainty in these low-input systems is currently lacking. W…
  • Electrocardiogram Recordings in Anesthetized Mice using Lead II. [Journal Article]
    J Vis Exp. 2020 Jun 20Ha TW, Oh B, Kang JO
  • The electrocardiogram is a valuable tool for evaluating the cardiac conduction system. Animal research has helped generate novel genetic and pharmacological information regarding the electrocardiogram. However, making electrocardiogram measurements in small animals in vivo, such as mice, has been challenging. To this end, we used an electrocardiogram recording method in anesthetized mice with man…
  • Tocilizumab in patients with severe COVID-19: A single-center observational analysis. [Journal Article]
    J Med Virol. 2020 Jun 17 [Online ahead of print]Knorr JP, Colomy V, … Ha S
  • Patients with coronavirus disease 2019 (COVID-19) may develop severe respiratory distress, thought to be mediated by cytokine release. Elevated proinflammatory markers have been associated with disease severity. Tocilizumab, an interleukin-6 receptor antagonist, may be beneficial for severe COVID-19, when cytokine storm is suspected. This is a retrospective single-center analysis of the records o…
  • Meat quality attributes and oxidation stability of loin chops from finishing gilts and cull sows. [Journal Article]
    J Food Sci Technol. 2020 Aug; 57(8):3142-3150.Song DH, Hwang YJ, … Kim HW
  • The objective of this study was to compare the meat quality attributes, color stability, and lipid oxidation of loin chops from finishing gilts and cull sows in a three-way crossbreeding system: landrace × large white × duroc finishing gilts (n = 20) and landrace × large white sows (n = 20). No significant differences in pH, proximate composition, or total collagen content were found between the …
  • Cell Energy Metabolism and Hyaluronan Synthesis. [Journal Article]
    J Histochem Cytochem. 2020 Jul 06 [Online ahead of print]Caon I, Parnigoni A, … Vigetti D
  • Hyaluronan (HA) is a linear glycosaminoglycan (GAG) of extracellular matrix (ECM) synthesized by three hyaluronan synthases (HASes) at the plasma membrane using uridine diphosphate (UDP)-glucuronic acid (UDP-GlcUA) and UDP-N-acetylglucosamine (UDP-GlcNAc) as substrates. The production of HA is mainly regulated by hyaluronan synthase 2 (HAS2), that can be controlled at different levels, from epige…
  • Frequency and diagnostic outcome of bilateral recall at screening mammography. [Journal Article]
    Int J Cancer. 2020 Jul 04 [Online ahead of print]Lameijer JR, Nederend J, … Duijm LE
  • This study was performed to determine the frequency of recall for bilateral breast lesions at screening mammography and compare its outcome with respect to unilateral recall. We included 329132 screening mammograms (34889 initial screens and 294243 subsequent screens) from a Dutch screening mammography programme between January 2013 and January 2018. During 2-year follow-up, we collected radiolog…
