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.

Carboniferous basement rocks of northern Britain [PDF]
, 1987 The study of Carboniferous basement rocks of northern Britain has concentrated on the dominantly clastic rock succession which unconformably overlies the Lower Palaeozoic basement and occurs beneath the lowermost Carboniferous limestones in areas ...

Pseudogzheloceras—a new genus of Carboniferous nautilids (Cephalopoda) from Europe and North Africa
Geo&Bio, 2021 Analysis of morphology, stratigraphic and geographic distribution of the group of nautilid species, mainly from the Westphalian of Western Europe, and the Bashkirian and Moscovian of the Donets Basin (Eastern Ukraine) made it possible to establish a new ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis
FEBS Letters, EarlyView.Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Comparative analysis of paleoclimatic data for Carboniferous and Permian of the Kuznetsk Basin
Учёные записки Казанского университета: Серия Естественные наукиThis article presents the results of a comparative analysis of paleoclimatic data on the late Paleozoic of the Kuznetsk Basin. Using existing simulations of the Phanerozoic climate, Köppen–Geiger climate types were identified for eight time intervals ...

Reconstructing enzyme evolution by protein engineering
FEBS 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 ...

The anelastic structure and deep geology of the Derbyshire Dome from high frequency Rayleigh waves. [PDF]
, 1984 This work is an investigation of the anelastic structure of the Derbyshire Dome and adjacent areas from the analysis of high frequency, 0.6 - 4.2 Hz, fundamental mode Rayleigh waves observed from quarry blasts within the study area.
