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.

The influence of reinforcement’s congestion to the strength of centrally compressed concrete members with GFRP reinforcement [PDF]

BIO Web of Conferences
The article presents the results of the computational analysis of compressed concrete columns of a water tank with GFRP reinforcement. It is analytically proved that with an increase in the confinement reinforcement ratio and the magnitude of the ...

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

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 ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

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.

SHEAR RESISTANCE OF R/C BEAMS PROVIDED WITH DIFFERENTLY-INCLINED TRANSVERSE REINFORCEMENT

, 2012
The model for the evaluation of shear resistance of reinforced concrete member provided with transverse web reinforcement, derived by Nielsen (1999) on the basis of the variable inclination stress field approach, is generalized here to predict the shear ...

Axial compression behavior of square concrete columns reinforced with longitudinal and transverse GFRP bars

Results in Engineering
This research assesses the performance of square concrete columns that have been reinforced with transverse reinforcement and longitudinal bars made of glass fiber-reinforced polymer (GFRP) under axial compression. Seven columns were subjected to testing,

Features of the Internal Force Factors Distribution in Reinforced Concrete Piles of Complex Cross Section under the Influence of a Transverse Load

Applied Sciences, 2023
Bar reinforced concrete structures, which include piles, in real working conditions perceive a whole range of internal force factors. Axial tension-compression forces, bending moments and shear forces are the most commonly perceived internal force ...

Effect of transverse reinforcement on the shear behavior of reinforced concrete deep beams

World Journal of Advanced Research and Reviews, 2022
Reinforced concrete deep beams are safety critical members that carry heavy loads over short spans (ACI Committee 318, 2008). Design provisions in many codes can under or overestimate their shear strength, which introduces reliability concerns in practice (Kong & Evans, 1987).
