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.

Selective Determination of 4,4′-Oxydianiline (4,4′-ODA) in Plastic Packaging Using Molecularly Imprinted Polymer Sensor Integrated with Pyrolyzed Copper/Carbon Composite

Chemosensors
This study focuses on the synthesis, fabrication, and characterization of a molecularly imprinted polymer (MIP) sensor tailored for the selective determination of 4,4′-oxydianiline (4,4′-ODA) in plastic products. Notably, by integrating the sensor matrix

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Effects of fiber properties on shrinkage of fiber/PMMA composite-based bone cements

, 2010
Fiber/polymethylmetacrylate (PMMA) composite bone cements were prepared with various fiber types (polyester and kevlar) in %1, 2 and 3 volumes. The shrinkage of the fiber/PMMA composite patterns were then calculated among 150 days. Results indicated that

Recent Advances in Diagnosing and Managing Phytoplasma Diseases

Agronomy
Phytoplasmas are obligate intracellular parasitic bacteria that infect over 1000 plant species globally, causing devastating diseases characterized by yellowing, witches’ broom, phyllody, and significant yield losses in economically important crops.

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.

Assessment of Segal method for identifying crystallinity evolution in developing cotton fibers

Agricultural & Environmental Letters
The crystallinity index (CI) is an important parameter in evaluating cotton fiber quality. Due to its ease and speed in measuring CIs from X‐ray diffraction (XRD) patterns, the Segal method is popularly used.
