Partial migration is a phenomenon where migratory and resident individuals of the same species co-exist within a population, and has been linked to both intrinsic (e.g., genetic) as well as environmental factors.

This article presents the rationale, challenges, and adaptive strategies employed during the initiation and execution of the arteriovenous (AV) access trial-a multicenter randomized controlled trial (RCT) comparing AV fistulas and AV grafts for hemodialysis in older adults with major comorbidities. Motivated by shifts in epidemiologic landscapes and evolving guidelines moving away from a fistula-first approach and to more patient-centric approaches, the objective of this randomized controlled trial was to fill critical knowledge gaps in determining the optimal vascular access for this complex patient population. We outline the challenges encountered in patient recruitment along with measures employed to overcome these obstacles in recruitment.

Article Synopsis
  • Top predators like black kites serve as indicators of ecosystem health, revealing how environmental contaminants impact them, particularly in long-lived species.
  • This study measured levels of metals and arsenic in black kites from Doñana National Park, noting increases over time and variations based on sex and breeding status.
  • Although contamination levels were high, particularly for lead, and negatively affected male breeding success, the research did not find clear links between metal exposure and survival or life expectancy, emphasizing the need for long-term ecological studies.

In recent years, theoretical and phenomenological studies with effective field theories have become a trending and prolific line of research in the field of high-energy physics. In order to discuss present and future prospects concerning automated tools in this field, the SMEFT-Tools 2022 workshop was held at the University of Zurich from 14th-16th September 2022. The current document collects and summarizes the content of this workshop.

Europium is one of the most reactive lanthanides and humans use it in many different applications, but we still know little about its potential toxicity and cellular response to its exposure. Two strains of the eukaryotic microorganism model were adapted to high concentrations of two Eu(III) compounds (EuCl or EuO) and compared to a control strain and cultures treated with both compounds. In this ciliate, EuCl is more toxic than EuO.
