Quantitative collagen and proteoglycan imaging reveal organic layering, gradients and regional texture in young mature dental cementum

open access: yesVIEW, EarlyView.
Cementum, the mineralized tissue covering all mammalian tooth roots, helps maintain tooth stability, but its internal organization is still poorly understood. In this study, we combine quantitative histologial methods to map the regional distributions of collagen fibers and proteoglycan‐rich matrix layers in porcine cementum.

Modeling and design of composite viscoelastic structures with high damping power

open access: yes, 2015
Modeling and design of composite viscoelastic structures with high damping powerThe aim of this thesis is to develop numerical tools to determine accurately damping properties of composite sandwich structures for the design of lightweight viscoelastic sandwichs structures with high damping power. In a first step, we developed a generic tool implemented

FPGA‐Based Real‐Time Implementation of Closed‐Loop Brain‐Controlled Eye Movement System

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT This paper presents a comprehensive closed‐loop brain‐eye movement framework, spanning parametric modelling, dynamic analysis and real‐time FPGA implementation. A simplified first‐order oculomotor model was derived from the classical Robinson formulation to preserve the essential neural‐mechanical feedback structure while enabling efficient ...

Human Embryonic Stem Cell‐Derived Immunity‐And‐Matrix‐Regulatory Cells Attenuate Pulmonary Fibrosis via MMP1‐Mediated Collagen Degradation

open access: yesCell Proliferation, EarlyView.
Human embryonic stem cell‐derived Immunity‐and‐Matrix‐Regulatory Cells (IMRCs) effectively attenuate pulmonary fibrosis by secreting Matrix Metalloproteinase‐1 (MMP1), which directly degrades excess collagen I in the extracellular matrix. By directly degrading collagen I, IMRCs reverse ECM stiffness, suppress myofibroblast activation, and promote a ...

Finite Element Analysis of Dentoalveolar Stress in Combat Sports Using Hybrid and Conventional Mouthguards

open access: yesDental Traumatology, EarlyView.
ABSTRACT Aim This study aimed to contribute to the development of modern mouthguards by evaluating the stresses generated by hook and uppercut punches applied during combat sports on dentoalveolar structures and mouthguards, the protective effectiveness of different mouthguard designs, and the resulting deformations using three‐dimensional finite ...

Artefact‐aware Brillouin microscopy framework for root mechanical phenotyping

open access: yesJournal of Microscopy, EarlyView.
Abstract Plant roots continuously sense and respond to the mechanical signals of their growth environment: root cap function, mucilage secretion, and hormonal regulation jointly adapt root tip mechanics, shaping whether roots penetrate compacted layers or reorient around obstacles. Most current measurements of root mechanical properties require removal
