A minimal cellulosome‐like system in Cellulosilyticum lentocellum

open access: yesFEBS Open Bio, EarlyView.
Cellulose‐degrading bacteria typically use cellulosomes, large multi‐enzyme complexes on a scaffold protein. In Cellulosilyticum lentocellum, we characterise a far smaller arrangement, a single scaffold bound to one cellulase through a single cohesin‐dockerin interaction.

Variation in distortion with magnification

open access: yesJournal of Research of the National Bureau of Standards, 1955
The distortion introduced in the image by a lens for a given axial inclination of the chief ray is a linear function of the magnification. Specifically, if D0 represents the distortion with parallel light incident on one side of the lens (zero magnification) and D∞ the distortion with parallel light incident on the other, then the distortion Dm at any ...

The C‐terminal truncated splicing variant of NK1R negatively modulates substance P‐stimulated NK1R signaling

open access: yesFEBS Open Bio, EarlyView.
The neurokinin 1 receptor exists as full‐length (NK1L) and C‐terminally truncated (NK1S) splice variants. We show that NK1S heterodimerizes with NK1L, impairing Gαq coupling and Ca2+ mobilization while enhancing β‐arrestin1 recruitment. NK1S suppresses substance P‐driven gene expression and cell migration, revealing NK1S as an endogenous biased ...

Comparative evaluation of caries detector dyes and laser fluorescence systems for intraoperative diagnosis during selective caries removal: a scoping review

open access: yesFrontiers in Dental Medicine
BackgroundSelective caries removal aims to preserve pulp vitality and tooth structure by eliminating only infected dentin. Caries detector dyes and laser fluorescence devices are the main diagnostic tools supporting this minimally invasive approach ...

Type I interferons modulate autophagy to shape gemcitabine response in pancreatic cancer cells

open access: yesFEBS Open Bio, EarlyView.
Type I interferons differentially modulate autophagy and the response of pancreatic cancer cells to gemcitabine. IFNα2b stimulates autophagic flux and protects cells from gemcitabine‐induced cell death, contributing to chemoresistance. In contrast, IFNβ1a inhibits autophagosome formation and enhances gemcitabine‐induced cell death, resulting in ...

Identification and characterization of a gene conferring stress resistance in Escherichia coli and cyanobacteria

open access: yesFEBS Open Bio, EarlyView.
Functional screening identified PcSyn14890, a cyanobacteria‐specific protein that enhances growth and stress resistance in E. coli and Synechocystis PCC6803. Although we expected it to function as a molecular chaperone, it was unable to protect against thermal aggregation of GAPDH.

Determinants of undergraduate bioscience engagement: Validating attendance barriers and classroom spatial behaviour across institutions

open access: yesFEBS Open Bio, EarlyView.
Student engagement extends beyond simple attendance. Across 891 bioscience students from three universities, attendance behaviour was associated mainly with structural influences, whereas classroom spatial behaviour reflected affective and sensory factors.
