Effect of Dietary Restriction on Muscle Performance in Drosophila [PDF]

, 2011
Dietary restriction (DR) can extend the lifespan in various organisms and is thought to present potential benefits in human. However, it is still a controversial issue now among scientists due to lack of strong supportive evidence in human.

Diversity and complexity in neural organoids

FEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Type I restriction-modification system and its resistance in electroporation efficiency in Flavobacterium columnare

, 2012
Flavobacterium columnare, the causative agent of columnaris disease, infects freshwater fish worldwide. However, the pathogenicity of this bacterium is poorly understood due possibly to the lack of an efficient in-frame knockout technique.

Molecular cloning and physical mapping of murine cytomegalovirus DNA [PDF]

, 1983
Murine cytomegalovirus (MCMV) Smith strain DNA is cleaved by restriction endonuclease HindIII into 16 fragments, ranging in size from 0.64 to 22.25 megadaltons.

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 ...

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 ...

The Restriction Activity Investigation of Rv2528c, an Mrr-like Modification-Dependent Restriction Endonuclease from Mycobacterium tuberculosis

Microorganisms
Mycobacterium tuberculosis (Mtb), as a typical intracellular pathogen, possesses several putative restriction–modification (R-M) systems, which restrict exogenous DNA’s entry, such as bacterial phage infection.

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.

Restriction of the growth of T7-like phages by plasmid prophage P1

Фактори експериментальної еволюції організмів, 2014
Aims. Considerable part of T7 phage genome is responsible for interaction with the bacterial host, primarily for the avoidance of action of protective systems of cells, the restriction-modification complexes.
