Ecological fitness impairments induced by chronic exposure to polyvinyl chloride nanospheres in .

The aim of this study was to evaluate the effects of chronic exposure (21 days) to an environmentally relevant concentration (10 μg/L) of two different nanoplastic (NP) polymers on the aquatic model organism . This study examined the impact of exposure to 200 nm polystyrene nanoplastics (PS-NPs) and polyvinyl chloride nanoplastics (PVC-NPs), which had an average size similar to that of PS-NPs (ranging from 50 nm to 350 nm). The effects of polymer exposure on morphometric parameters, number of molts, swimming behaviour, and reproductive outcomes were evaluated.

How do we transfuse children in Italy? Results of a national survey.

Background: Adherence to optimal practices in the preparation and issuance of pediatric blood components can significantly influence patient care outcomes. This study aims to examine the blood banking procedures across prominent Italian children's hospitals, with the goal of identifying both consistent and potentially divergent standards within this field.

Materials And Methods: A survey was conducted among the blood banks affiliated with the Italian Association of Pediatric Hospitals.

Ceftaroline for bloodstream infections caused by methicillin-resistant Staphylococcus aureus: a multicentre retrospective cohort study.

Objectives: To evaluate the effectiveness of ceftaroline vs. vancomycin or daptomycin in the treatment of methicillin-resistant Staphylococcus aureus bloodstream infections (BSIs) (MRSA-BSIs).

Methods: This multicentre retrospective study conducted in 15 Spanish hospitals included data from the first MRSA-BSIs of adult patients between January 2019 and December 2022.

Extensive longevity and DNA virus-driven adaptation in nearctic bats.

The genus is one of the largest clades of bats, and exhibits some of the most extreme variation in lifespans among mammals alongside unique adaptations to viral tolerance and immune defense. To study the evolution of longevity-associated traits and infectious disease, we generated near-complete genome assemblies and cell lines for 8 closely related species of . Using genome-wide screens of positive selection, analyses of structural variation, and functional experiments in primary cell lines, we identify new patterns of adaptation contributing to longevity, cancer resistance, and viral interactions in bats.
