Nano versus bulk: Evaluating the toxicity of lanthanum, yttrium, and cerium oxides on Enchytraeus crypticus.

Considering the increase in demand for rare earth elements (REEs) and their accumulation in soil ecosystems, it is crucial to understand their toxicity. However, the impact of lanthanum, yttrium and cerium oxides (LaO, YO and CeO, respectively) on soil organisms remains insufficiently studied. This study aims to unravel the effects of LaO, YO and CeO nanoparticles (NPs) and their corresponding bulk forms (0, 156, 313, 625, 1250 and 2500 mg/kg) on the terrestrial species Enchytraeus crypticus.

Induction of Fc-dependent functional antibodies against different variants of SARS-CoV-2 varies by vaccine type and prior infection.

Background: SARS-CoV-2 transmission and COVID-19 disease severity is influenced by immunity from natural infection and/or vaccination. Population-level immunity is complicated by the emergence of viral variants. Antibody Fc-dependent effector functions are as important mediators in immunity.

Role of Hydration and Amino Acid Interactions on the Ion Permeation Mechanism in the hNa1.5 Channel.

This study explores the ion selectivity and conduction mechanisms of the hNa1.5 sodium channel using classical molecular dynamics simulations under an externally applied electric field. Our findings reveal distinct conduction mechanisms for Na and K, primarily driven by differences in their hydration states when they diffuse close to the channel's selective filter (DEKA) and extracellular ring (EEDD).

Meningitis by Streptococcus suis: Case Report of a Critically Ill Patient.

is a zoonotic pathogen commonly found in pigs, capable of causing disease in humans when in contact with contaminated pigs or pork products. The most common presentation in humans is meningitis, although it can also manifest as sepsis, arthritis, endocarditis, or endophthalmitis. In Europe, most cases are described as occupational disease related to pig farming or raw pork handling.

The Hunga Tonga-Hunga Ha'apai volcanic barometric pressure pulse and meteotsunami travel recorded in several Antarctic stations.

The Hunga Tonga-Hunga/Hunga-Ha'apai eruption on January 15, 2022 sent off a plume of ash material up to the stratosphere and triggered a meteotsunami and barometric pressure pulse that rippled through the atmosphere and oceans all around the world. The nature of the volcanic event and its global impacts on the oceans, atmosphere, lithosphere and the cryosphere are a matter of debate. Here we present a first overview of the time travel of the sound atmospheric pressure wave through the Antarctic continent based on in situ measurements, which represented a unique event observed through the polar ice sheet during the instrumental meteorological era.
