An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane
FEBS Letters, EarlyView.Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Low-cost chemical experiments: a contribution from the microscale
Revista Eureka sobre Enseñanza y Divulgación de las Ciencias, 2012 Experimental activities in laboratories are an important part in teaching and learning Chemistry. However, its implementation can normally be affected by a lack of materials, instruments, reagents price and the risks related to non-proper manipulation ...

FEBS Letters, EarlyView.Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Group discussions in secondary school chemistry: Unveiling pedagogical alchemy for academic advancement [PDF]
Journal of Pedagogical ResearchChemistry education in Rwandan secondary schools faces challenges, especially after the adoption of a competence-based curriculum that prioritizes student-centered learning. Traditional teacher-centered approaches often result in poor student performance.

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
