Structural basis for the adsorption of a single-stranded RNA bacteriophage

open access: yesNature Communications, 2019
Single-stranded RNA bacteriophages use a single maturation protein (Mat) to attach to a retractile pilus of the bacterial host. Here, the authors report the structures of the MS2 phage bound to the host receptor F-pili and define the orientations of Mat ...

Photophobotaxis of single‐celled and filamentous cyanobacteria

open access: yesPhotochemistry and Photobiology, EarlyView.
LED illumination from below induces central accumulation of cyanobacterial species. Abstract Phototaxis refers to an organism's movement toward a light source, while photophobotaxis involves movement into illuminated regions. Although phototaxis in cyanobacteria has been widely studied, photophobotaxis has been investigated in only a few species.

In situ structures of the genome and genome-delivery apparatus in a single-stranded RNA virus. [PDF]

open access: yes, 2016
Packaging of the genome into a protein capsid and its subsequent delivery into a host cell are two fundamental processes in the life cycle of a virus. Unlike double-stranded DNA viruses, which pump their genome into a preformed capsid, single-stranded ...

Analysis of the heterogenous structural states of the hexameric ATPase PilU of the type IV pili from Vibrio cholerae

open access: yesProtein Science, Volume 35, Issue 6, June 2026.
Abstract Type IV pili (T4P) mediate surface motility, host interactions, and DNA uptake through cycles of extension and retraction. While the primary retraction ATPase PilT has been extensively characterized, its homolog PilU remains less well understood despite being demonstrated as a PilT‐dependent retraction ATPase.

Pseudomonas aeruginosa pilin activates the inflammasome [PDF]

open access: yes, 2011
IL-1 beta is produced from inactive pro-IL-1 beta by activation of caspase-1 brought about by a multi-subunit protein platform called the inflammasome. Many bacteria can trigger inflammasome activity through flagellin activation of the host protein NLRC4.

Cardiorespiratory and Hematological Responses to High‐Intensity Interval Training in Adolescent Girls With Overweight or Obesity: A Randomized Controlled Trial

open access: yesEuropean Journal of Sport Science, Volume 26, Issue 5, May 2026.
ABSTRACT This randomized controlled trial examined the effects of a 10‐week high‐intensity interval training (HIIT) program on physiological and hematological outcomes in 28 adolescent girls with overweight or obesity. Participants were randomly assigned to a HIIT group or a control group. The HIIT protocol comprised 4 sets of 6 × 15‐s bouts at 90%–105%

Unusual Metabolism and Hypervariation in the Genome of a Gracilibacterium (BD1-5) from an Oil-Degrading Community. [PDF]

open access: yes, 2019
The candidate phyla radiation (CPR) comprises a large monophyletic group of bacterial lineages known almost exclusively based on genomes obtained using cultivation-independent methods.

Structural insights into the Thermus thermophilus type IV pilus machinery assembling two distinct pili

open access: yesCommunications Biology
Type IV pili are long, filamentous structures that extend from bacterial cell surfaces, enabling cells to respond to changing environments and facilitating genome plasticity.

Impact of conductive magnetite nanoparticles and anode polarization on glucose fermentation

open access: yesJournal of Chemical Technology &Biotechnology, Volume 101, Issue 5, Page 1027-1034, May 2026.
Abstract BACKGROUND Electrically conductive materials and electrochemical stimulation strategies are increasingly explored to steer microbial fermentation towards desired metabolic outputs. These approaches also hold remarkable potential to couple wastewater treatment (WWT) to the production of value‐added compounds, in turn enhancing environmental ...
