Migrasomes, Matrix‐Bound Nanovesicles, and More: Messengers in the Matrix

PROTEOMICS, EarlyView.
ABSTRACT Extracellular vesicles (EVs) and particles (EPs) are diverse micro‐ and nanoparticles that circulate in bodily fluids and can attach to, or be deposited onto, the extracellular matrix (ECM) and other surfaces. To date, the nomenclature and classification of matrix‐bound or matrix‐associated EVs and EPs (MEVPs) have been unclear, largely due to

Impact of elevated sclerostin levels on bone resorption: unravelling structural changes and mineral metabolism disruption

Bone & Joint Research
Aims: The physiological function of sclerostin remains unknown. Sclerostin is synthesized by osteocytes and operates by inhibiting the Wnt/β-catenin pathway. Similarly, it is well established that low levels of sclerostin lead to enhanced bone formation

The N‐Glycome to Differentiate Mesenchymal Stem Cells Upon Chondrogenic Differentiation, Dedifferentiation, and Senescence

PROTEOMICS, EarlyView.
ABSTRACT Mesenchymal stem cells (MSCs) are adult stem cells able to self‐renewal or differentiation into different cell types, including chondrocytes. N‐Glycans are post‐translational modifications of glycoproteins that contribute to vital cell functions.

Hybrid Multiphoton Lithography Scaffolds for Nanoscale Mechanobiological Assessment in Microscale Bone Models

Small, EarlyView.
This work presents a 3D hybrid tissue scaffold inspired by bone, incorporating collagen, fabricated using multiphoton lithography. The mechanical properties of collagen are tunable, and biodegradation allows for time‐dependent changes in geometry. The results demonstrate enhanced osteogenic differentiation of stem cells in our hybrid scaffolds.

Quantitative micro‐XRF combined with X‐ray imaging reveals correlations between Zn concentration and dentin tubule porosity across entire teeth

VIEW, EarlyView.
The combination of calibrated micro‐CT and quantitative micro‐XRF measurement facilitates the correlation of density and composition in the 3D macro‐structure of teeth. Zn concentration in dentin increases by a factor of 10 toward the pulp. Incidentally, the overall density decreases, showing an association between Zn and the dentin tissue porosity ...

Adaptability Checking in Multi-Level Complex Systems

, 2014
A hierarchical model for multi-level adaptive systems is built on two basic levels: a lower behavioural level B accounting for the actual behaviour of the system and an upper structural level S describing the adaptation dynamics of the system.

Harnessing energy metabolism for enhanced bone defect repair: Mechanisms and therapeutic strategies

VIEW, EarlyView.
This review addresses the critical challenge of bone defect repair by focusing on the underexplored role of cellular energy metabolism. It synthesizes regulatory mechanisms in bone‐forming cells and sums up innovative strategies—leveraging cell derivatives, active factors, and biomimetic scaffolds—to modulate metabolism for enhanced regeneration.

A Clinical Study of the Distribution and Morphology of Harris Lines

Archaeometry, EarlyView.
ABSTRACT Harris lines are commonly used in bioarcheology to infer lifestyle in ancient populations; however, their etiology and identification parameters are still under debate. The aim of this study is to observe the distribution of the lesions in a contemporary clinical sample to address their association with etiological factors, age, biological sex,

Biochemical bone biomarkers in plasma cell dyscrasias

British Journal of Haematology, EarlyView.
Visual abstract depicting that bone turnover markers reflect dynamic alterations in bone remodelling across the spectrum of plasma cell dyscrasias but remain limited by assay variability, biological confounding and incomplete integration with imaging and risk stratification.

Physiological Basis of Sex Differences in Human Performance and Exercise‐Associated Pathology

Clinical Endocrinology, EarlyView.
ABSTRACT The presence of sex differences in human physical performance is well‐established and shaped by distinct endocrine, anatomical and physiological mechanisms. Despite sustained advances, our understanding of how inherent biological factors drive variations in exercise capacity and related pathologies is still developing.
