Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Accurate Spectroscopy of Intermediate and Late Spectral Types [PDF]
Symposium - International Astronomical Union, 1988 Elemental abundances in the Sun and in meteorites are examined with respect to their qualification as a standard ofpopulation I composition. Some problems that arise in connection with spectroscopic determinations of abundances in the Sun, and in other late-type stars, are discussed with emphasis onphotospheric modelsanddepartures from LTE.

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 ...

Molecular Architecture of a Late 40S Ribosome Assembly Intermediate [PDF]
Biophysical Journal, 2012 Ribosomes are self-assembling macromolecular machines which catalyze the synthesis of proteins in all cells, and are made up of two subunits that differ in size due to the presence of RNA and proteins in different ratio. Although significant structural details of the organization of mature ribosomes in prokaryotes and eukaryotes have been elucidated in

FEBS 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.

Design and analysis strategies for robust microbiome ageing research
FEBS 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
