His bundle in phylogenesis, ontogenesis and pathology [PDF]

open access: yes, 2018
His bundle is a part of the cardiac conduction system of mammals, birds and crocodilians. His bundle is important for high cardiac output in endothermic vertebrates.

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

open access: yesFEBS 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 ...

Full-field optical coherence tomography using a fibre imaging bundle [PDF]

open access: yes, 2006
An imaging fibre bundle is demonstrated for spatially-multiplexed probe beam delivery in OCT, with the aim of eliminating the mechanical scanning currently required at the probe tip in endoscopic systems.

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

open access: yesFEBS 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 ...

Cardiomyocyte apoptosis in cocaine-induced myocarditis with involvement of bundle of His and left bundle branch

open access: yes, 2006
Cocaine abuse can cause degenerative and inflammatory alterations of the myocardium. Cocaine-induced myocarditis has been previously described, but mostly in chronic cocaine addicts.

The human gut microbiome across the life course

open access: yesFEBS 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.

Retrograde His bundle deflection in bundle-branch re-entry.

open access: yes, 1976
Atrial echo beats resulting from a reciprocating mechanism involving the bundle-branches were produced by premature atrial impulses in a patient with an A-V nodal bypass tract. The mechanism of the arrhythmia was suggested by the presence of a retrograde

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

open access: yesFEBS 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.

Updates on His bundle pacing: The road more traveled lately [PDF]

open access: yes, 2018
His bundle pacing (HBP) has continued to evolve over the past decade and has started to become a global phenomenon. Evidence is mounting of its clinical benefits as compared to both right ventricular and left ventricular pacing.
