Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

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 ...

Investigação do controle por regras e do controle por histórias de reforço sobre o comportamento humano Investigation of rule control by controlling the effetcts of reinforcement history on human behavior

Psicologia: Reflexão e Crítica, 2004
Este estudo investigou, com 16 universitários, o papel da história de reforço e da densidade relativa de reforço no seguimento de regra. Utilizou-se um procedimento de escolha segundo o modelo, com 3 estímulos de comparação; a tarefa consistia em apontar

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

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 ...

Alternative Rule‐Out Cutoffs for a Novel High‐Sensitivity Cardiac Troponin I Assay in Patients With Suspected Myocardial Infarction

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background There is major uncertainty among physicians on how to best use the novel hs‐cTnI (high sensitivity‐cardiac troponin I)‐VITROS assay, as the limit of quantification (2 ng/L), applied by the US Food and Drug Administration and other regulators ...

The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.
