Uneven consequences of global climate mitigation pathways on regional water quality in the 21st century.

Future socioeconomic climate pathways have regional water-quality consequences whose severity and equity have not yet been fully understood across geographic and economic spectra. We use a process-based, terrestrial-freshwater ecosystem model to project 21st-century river nitrogen loads under these pathways. We find that fertilizer usage is the primary determinant of future river nitrogen loads, changing precipitation and warming have limited impacts, and CO fertilization-induced vegetation growth enhancement leads to modest load reductions.

[Status epilepticus in a pregnant patient with a previously unrecognized POLG-associated disease].

-associated diseases are rare causes of pharmacoresistant epilepsy and status epilepticus, especially in adult patients. Phenotypic and genotypic variability in these conditions causes the complexity of their diagnosis. In the study, we report a case of a 33-year-old female patient who developed recurrent convulsive status epilepticus with focal clonic onset at the week 22/23 of pregnancy.

Neuroinflammatory Dysfunction of the Blood-Brain Barrier and Basement Membrane Dysplasia Play a Role in the Development of Drug-Resistant Epilepsy.

Drug-resistance epilepsy (DRE) is a key problem in neurology. It is possible that damage to the blood-brain barrier (BBB) may affect resistance in DRE. The aim of this work was to assess the damage and dysfunction in the BBB in the area of epileptic foci in patients with DRE under conditions of neuroinflammation.

Abrupt loss and uncertain recovery from fires of Amazon forests under low climate mitigation scenarios.

Tropical forests contribute a major sink for anthropogenic carbon emissions essential to slowing down the buildup of atmospheric CO and buffering climate change impacts. However, the response of tropical forests to more frequent weather extremes and long-recovery disturbances like fires remains uncertain. Analyses of field data and ecological theory raise concerns about the possibility of the Amazon crossing a tipping point leading to catastrophic tropical forest loss.

Ni/(RO,CaO) Nanocomposites Produced by the Exsolution of RCaNiO Nickelates (R = Nd, Sm, Eu): Rare Earth Effect on the Catalytic Performance in the Dry Reforming and Partial Oxidation of Methane.

In order to clarify the role of RO in the metal-oxide catalysts derived from complex oxide precursors, a series of RCaNiO (R = Nd, Sm, Eu) complex oxides was obtained. A significant systematic increase in the orthorhombic distortion of the RCaNiO structure (KNiF type, Cmce) from Nd to Eu correlates with a corresponding decrease in their ionic radii. A reduction of RCaNiO in the Ar/H gas mixture at 800 °C causes a formation of dense agglomerates of CaO and RO coated with spherical 25-30 nm particles of Ni metal.
