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

FEBS 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.

Critical Size and Doping Thresholds Governing Band Gap Evolution in Semiconductors

East European Journal of Physics
Understanding how the band gap ( Eg) of semiconductors evolves with size, dimensionality, and doping concentration is crucial for optimizing modern electronic and optoelectronic devices. In this work, we perform a systematic analysis of critical sizes (

Structure‐forward targeting of claudins with synthetic binders

FEBS Letters, EarlyView.
Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.

Preparation and analysis of structural, morphological and optical properties of BaFeO2.67/Fe2O3 nanocomposite

Scientific Reports
This research presents the synthesis of BaFeO2.67/Fe2O3 nanocomposite using a simple chemical co-precipitation method without any capping agents, which distinguishes it from existing methodologies.

Multi-Temporal Canopy Gaps Assessment Using Airborne Laser Scanning Data: The Case of the Protected Forests in the Carpathian Montane Ecosystem in Poland

Remote Sensing
Canopy gaps are important footprints in understanding the forests’ disturbance regime and regeneration process, yet there is a need to employ multiple metrics along the gradient of time for a deeper understanding of the dynamics.

Influence of Inter-row Gap Value on Turbine Losses

International Journal of Rotating Machinery, 2001
This paper presents the results of a numerical investigation of the gap influence on the turbine efficiency. The rotor-stator interaction in a (1/2)-stage turbine is simulated by solving the quasi-three-dimensional unsteady Euler/Navier-Stokes equations ...

Nutrient/TOR signaling controls adipose mitochondrial transcription factor A (TFAM) to regulate organismal growth in Drosophila

FEBS Letters, EarlyView.
Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...
