The enterobacterial common antigen (ECA) is conserved in Gram-negative bacteria of the order although its function is debated. ECA biogenesis depends on the Wzx/Wzy-dependent strategy whereby the newly synthesized lipid-linked repeat units, lipid III, are transferred across the inner membrane by the lipid III flippase WzxE. WzxE is part of the Wzx family and required in many glycan assembly systems, but an understanding of its molecular mechanism is hindered due to a lack of structural evidence.

  • Lov'U'r Teeth is a French dental health program aimed at children aged 6 to 15, offering free preventive dental care and individual advice, but it was previously under-utilized.
  • A study analyzing data from over 26,000 children found that participation increased by 4.2 percentage points from 2009 to 2019, with the highest participation at age 6 and significant barriers for children from low-income households.
  • Despite some improvement, the program still reflects social inequalities, as poorer children are less likely to participate, indicating a need for better outreach and communication about the program's benefits.

The Omicron strains of SARS-CoV-2 pose a significant challenge to the development of effective antibody-based treatments as immune evasion has compromised most available immune therapeutics. Therefore, in the 'arms race' with the virus, there is a continuing need to identify new biologics for the prevention or treatment of SARS-CoV-2 infections. Here, we report the isolation of nanobodies that bind to the Omicron BA.

In France, blood donations are tested in pools of 96 samples for parvovirus B19 (B19V) DNA to discard plasma for fractionation when it contains high viral loads. Between January 2015 and March 2024, B19V-positive donations decreased during the COVID-19 pandemic, followed by a strong rebound in 2023 and unusually high circulation during winter 2023/24 (ca 10 times higher December 2023-March 2024 vs the pre-pandemic period). Variations over time are probably related to measures implemented to limit SARS-CoV-2 spread.

Article Synopsis
  • Dental avulsion injuries in children significantly impact their quality of life, with the study focusing on the Pediatric Oral Health-Related Quality of Life (POQL) scores from the children's perspective.
  • The cross-sectional study involved 40 children aged 8-14 who had experienced dental avulsion and compared their scores to 40 healthy peers, revealing higher POQL scores in girls, particularly in social and emotional aspects.
  • The findings suggest that while the repositioning of avulsed teeth does not significantly affect POQL scores, emotional well-being is still impacted, highlighting the need for psychological support following such injuries to mitigate negative effects.
