BMC Nephrol

October 2024

Division of Nephrology and Hypertension, Inselspital, Bern University Hospital, University of Bern, Freiburgstrasse 18, Bern, 3010, Switzerland.

Article Synopsis
  • There is uncertainty around the use of apixaban in patients undergoing hemodialysis due to inconsistent study results and conflicting recommendations from health authorities, highlighting the need for further investigation into appropriate dosing.
  • A study was conducted analyzing pre-dialysis apixaban levels in 24 patients with different dosing regimens, finding that higher drug levels were associated with twice daily dosing compared to once daily, and demonstrating that some patients had undetectable levels.
  • The analysis also revealed that patients who experienced bleeding events had significantly higher drug levels and a majority of these patients were on concomitant antiplatelet therapy, suggesting that drug monitoring could enhance patient safety in this population.

  • - AAV2 is a small, non-harmful parvovirus that requires a helper virus like adenovirus or herpes simplex virus to replicate its DNA, using different mechanisms depending on the helper virus involved.
  • - Recent findings reveal that AAV2 replication supported by HSV-1 leads to a different replication method called rolling circle replication (RCR), while adenovirus leads to strand-displacement rolling hairpin (RHR) replication.
  • - Understanding how AAV2 adapts its replication process based on the helper virus is crucial for enhancing gene therapy vector production and advancing our knowledge of viral biology.

A previously published genome-wide association study (GWAS) meta-analysis across eight neuropsychiatric disorders identified antagonistic single-nucleotide polymorphisms (SNPs) at eleven genomic loci where the same allele was protective against one neuropsychiatric disorder and increased the risk for another. Until now, these antagonistic SNPs have not been further investigated regarding their link to brain structural phenotypes. Here, we explored their associations with cortical surface area and cortical thickness (in 34 brain regions and one global measure each) as well as the volumes of eight subcortical structures using summary statistics of large-scale GWAS of brain structural phenotypes.

Metal-support interactions in metal oxide-supported atomic, cluster, and nanoparticle catalysis.

Chem Soc Rev

October 2024

Schulich Faculty of Chemistry, and Resnick Sustainability Center for Catalysis, Technion, Israel Institute of Technology, Technion City, Haifa 32000, Israel.

Supported metal catalysts are essential to a plethora of processes in the chemical industry. The overall performance of these catalysts depends strongly on the interaction of adsorbates at the atomic level, which can be manipulated and controlled by the different constituents of the active material (, support and active metal). The description of catalyst activity and the relationship between active constituent and the support, or metal-support interactions (MSI), in heterogeneous (thermo)catalysts is a complex phenomenon with multivariate (dependent and independent) contributions that are difficult to disentangle, both experimentally and theoretically.

Curr Opin Psychol

December 2024

Faculty of Business and Economics, University of Lausanne, 1015 Lausanne, Switzerland. Electronic address:

Numerous psychological biases shape how we respond to observing others conforming to or diverging from social norms. Depending on our social networks, we may be more influenced by societal majorities, such as the widespread consumption of meat or frequent air travel, or by the sustainable lifestyles of our closest friends. The evolution of social norms is shaped by personal preferences, values, beliefs, and the structure of social networks.
