Fibre-reinforced composites for dental applications [PDF]

BioMed Research International, 2008
Publisher Summary A new group of non-metallic dental biomaterials that are increasingly being used in dental applications are Fibre-Reinforced Composites (FRCs). FRC is a material combination of polymer matrix and reinforcing fibres. Fibres of the composite act as the reinforcing phase when the load is applied to the composite. Load is transferred to–

Prediction of stiffness and stresses in z-fibre reinforced composite laminates [PDF]

, 2002
The mechanical properties of z-pinned composite laminates were examined numerically. Finite element calculations have been performed to understand how the through-thickness reinforcement modifies the engineering elastic constants and local stress ...

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.

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 ...
