Pervaporation as a Successful Tool in the Treatment of Industrial Liquid Mixtures.

Pervaporation is one of the most active topics in membrane research, and it has time and again proven to be an essential component for chemical separation. It has been employed in the removal of impurities from raw materials, separation of products and by-products after reaction, and separation of pollutants from water. Given the global problem of water pollution, this approach is efficient in removing hazardous substances from water bodies.

Matched Cohort Study of Convalescent COVID-19 Plasma Treatment in Severely or Life Threateningly Ill COVID-19 Patients.

Background: The utility of convalescent coronavirus disease 2019 (COVID-19) plasma (CCP) in the current pandemic is not well defined. We sought to evaluate the safety and efficacy of CCP in severely or life threateningly ill COVID-19 patients when matched with a contemporaneous cohort.

Methods: Patients with severe or life-threatening COVID-19 were treated with CCP according to Food and Drug Administration criteria, prioritization by an interdisciplinary team, and based on CCP availability.

Massive transfusion: blood component ratios.

Purpose Of Review: This review will address recent developments in the transfusion management of massively transfused trauma patients, focusing on the use of fixed blood component ratios in massive transfusion protocols.

Recent Findings: The majority of trauma centers have migrated from laboratory-based transfusion protocols to massive transfusion protocols with fixed blood component ratios. These protocols with red blood cell : plasma : platelet ratio of 1 : 1 : 1 are associated with improved survival in severely injured patients.

Transgenic mouse model of tau pathology in astrocytes leading to nervous system degeneration.

Filamentous tau inclusions in neurons and glia are neuropathological hallmarks of sporadic and familial tauopathies. Because tau gene mutations are pathogenic for the autosomal dominant tauopathy "frontotemporal dementia and parkinsonism linked to chromosome 17," tau abnormalities are implicated directly in the onset and/or progression of disease. Although filamentous tau aggregates are acknowledged to play roles in degenerative mechanisms resulting in neuron loss, the contributions of glial tau pathology to neurodegeneration remain essentially unexplored.
