Viruses of Polar Aquatic Environments [PDF]

Viruses, 2019
The poles constitute 14% of the Earth’s biosphere: The aquatic Arctic surrounded by land in the north, and the frozen Antarctic continent surrounded by the Southern Ocean. In spite of an extremely cold climate in addition to varied topographies, the polar aquatic regions are teeming with microbial life.

Recurrent Hypothermia and Autonomic Dysfunction Secondary to Shapiro Syndrome

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT A 44‐year‐old man presented with recurrent hypothermia, diaphoresis and hypertension. Extensive investigation for infectious, inflammatory, metabolic and endocrine aetiologies was negative. MR scan of the brain demonstrated no lesions but revealed callosal dysgenesis, consistent with Shapiro syndrome.

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

Advanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

NH3 release during the evaporation of different types of atmospheric precipitation: A case study in Changchun, China

Scientific Reports
Ammonia (NH3) is a key precursor of secondary inorganic aerosols. During precipitation, NH3 in the atmosphere can be captured by rain and converted to NH4 +, whereas during evaporation, NH4 + can become NH3 and be released again.
