Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

An Illusion of Size [PDF]

open access: yesNature, 1945
IN his letter, Mr. J. Phelps1 refers to an interesting point in the manufacture of threepences, namely, their expansion in the coining press into dodecagonal steel collars. The fact that the corners of coins subsequent to 1940 are more rounded than are those of earlier ones seems to point to a change in the collars at about that date.

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Investigating transcription factor dynamics in health and disease using FRAP

open access: yesFEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

open access: yesFEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

A study on the printability properties of alkali-sized recycled papers

open access: yesScience and Engineering of Composite Materials, 2016
Recycled handsheets were prepared from old newspapers and old office papers with internal sizing applications of alkyl ketene dimer (AKD) emulsion at 0.5%, 1.0% and 1.5% addition levels as received basis.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

open access: yesFEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

'Worst month’ and ‘critical period' methods for the sizing of solar irrigation systems - A comparison

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2018
Despite the fact that solar photovoltaic (PV) water pumping systems, in particular, irrigation systems have been in use for more than 40 years, there remains a need for their improvement and development.
