Variability of extracorporeal cardiopulmonary resuscitation practice in patients with out-of-hospital cardiac arrest from the emergency department to intensive care unit in Japan.

Acute Med Surg 2021 Jan-Dec;8(1):e647. Epub 2021 May 1.

Department of Emergency and Critical Care Medicine Keio University School of Medicine Tokyo Japan.

Aim: A lack of known guidelines for the provision of extracorporeal cardiopulmonary resuscitation (ECPR) to patients with out-of-hospital cardiac arrest (OHCA) has led to variability in practice between hospitals even in the same country. Because variability in ECPR practice has not been completely examined, we aimed to describe the variability in ECPR practice in patients with OHCA from the emergency department (ED) to the intensive care units (ICU).

Methods: An anonymous online questionnaire to examine variability in ECPR practice was completed in January 2020 by 36 medical institutions who participated in the SAVE-J II study. Read More

Winter melt trends portend widespread declines in snow water resources.

Nat Clim Chang 2021 5;2021. Epub 2021 Apr 5.

Institute of Arctic and Alpine Research, University of Colorado Boulder, CO.

In many mountainous regions, winter precipitation accumulates as snow that melts in spring and summer, providing water to one billion people globally. Climate warming and earlier snowmelt compromises this natural water storage. While snowpack trend analyses commonly focus on snow water equivalent (SWE), we propose that trends in accumulation season snowmelt serve as a critical indicator of hydrologic change. Read More

Longitudinal study based on a safety registry for malaria patients treated with artenimol-piperaquine in six European countries.

Malar J 2021 May 8;20(1):214. Epub 2021 May 8.

TropNet, A European Network for Tropical and Travel Medicine, Verona, Italy.

Background: European travellers to endemic countries are at risk of malaria and may be affected by a different range of co-morbidities than natives of endemic regions. The safety profile, especially cardiac issues, of artenimol (previously dihydroartemisinin)-piperaquine (APQ) Eurartesim during treatment of uncomplicated imported falciparum malaria is not adequately described due to the lack of longitudinal studies in this population. The present study was conducted to partially fill this gap. Read More

Metabolic tradeoffs control biodiversity gradients through geological time.

Curr Biol 2021 May 3. Epub 2021 May 3.

Department of Geological Sciences, Stanford University, Stanford, CA 94305, USA.

The latitudinal gradient of increasing marine biodiversity from the poles to the tropics is one of the most conspicuous biological patterns in modern oceans. Low-latitude regions of the global ocean are often hotspots of animal biodiversity, yet they are set to be most critically affected by anthropogenic climate change. As ocean temperatures rise and deoxygenation proceeds in the coming centuries, the volume of aerobically viable habitat is predicted to decrease in these zones. Read More

Manipulation of CO adsorption over Me/CeO by heterocation doping: Key roles of single-atom adsorption energy.

J Chem Phys 2021 Apr;154(16):164705

Applied Chemistry, Waseda University, 3-4-1, Okubo, Shinjuku, Tokyo 169-8555, Japan.

The performance of metal atoms chemically bonded to oxide supports cannot be explained solely by the intrinsic properties of the metals such as the d-band center. Herein, we present an in-depth study of the correlation between metal-oxide interactions and the properties of the supported metal using CO adsorption on Me (Fe, Co, and Ni) loaded over CeO (111) doped with divalent (Ca, Sr, and Ba), trivalent (Al, Ga, Sc, Y, and La), and quadrivalent (Hf and Zr) heterocations. CO adsorption over Me is strongly dependent on the binding energies of Me. Read More

The metastasis suppressor protein NM23-H1 modulates the PI3K-AKT axis through interaction with the p110α catalytic subunit.

Oncogenesis 2021 Apr 30;10(4):34. Epub 2021 Apr 30.

Department of Otorhinolaryngology-Head and Neck Surgery, Perelman School of Medicine, Tumor Virology Program, Abramson Cancer Center, University of Pennsylvania, Philadelphia, PA, USA.

The PI3K pathway is one of the most deregulated pathways in cancer, which is predominantly due to gain of function mutations or altered expression of the PI3KCA gene. This is codified by what is seen for the class I PI3K catalytic subunit p110α, a common feature of many cancers. The metastasis suppressor protein NM23-H1 (NME1), whose ability to suppress the metastasis activities of different tumors has been widely described and was previously reported to alter phosphatidylinositol signaling.
