The Acquisition of Stylistic Variation by Jakarta Indonesian Children [PDF]

, 2014
To become competent speakers in their community, children have to learn the grammatical rules and lexicon of one or more language varieties. In addition, they need to learn when to use these varieties and to adapt their speech to both topic and setting ...

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 ...

Adaptation by Phase Variation in Pathogenic Bacteria

, 2003
Publisher Summary This chapter focuses on the transitions that are facilitated by the switching of phase-variable genes, thereby focusing on pathogenic bacteria. The ability to adapt to changing environments is essential for the survival, development, and evolution of bacterial species.

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 ...

Human Circadian Phase Estimation from Signals Collected in Ambulatory Conditions Using an Autoregressive Model [PDF]

, 2013
Phase estimation of the human circadian rhythm is a topic that has been explored using various modeling approaches. The current models range from physiological to mathematical, all attempting to estimate the circadian phase from different physiological ...

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.

Phase variable colony morphotypes of Clostridioides difficile elicit distinct host responses during acute infection

Infection and Immunity
Many Clostridioides difficile strains can form two colony morphotypes: rough and smooth. The rough and smooth morphotypes differ in multiple phenotypes, including cell length and chaining, motility, biofilm production, and virulence in the hamster model ...

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.

Genetic control of Group 3 (K96) capsule synthesis and complement resistance in extraintestinal pathogenic Escherichia coli

mSphere
Extraintestinal pathogenic Escherichia coli (ExPEC) frequently produce Group 2 or 3 capsules that enhance virulence, yet genetic regulation and specific roles of Group 3 capsules remain poorly understood. Here, we demonstrate that the K96 Group 3 capsule

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.
