Mechanical Activation of Piezo1 Drives Osteoarthritis Through Kdm5c‐Mediated Epigenetic Silencing

open access: yesAdvanced Science, EarlyView.
Excessive mechanical stress activates Piezo1, triggering Ca2+‐dependent cytoskeletal forces that deform the nucleus and reduce H3K4me3. Kdm5c demethylates H3K4me3 at Col2a1 and Runx3 promoters. Kdm5c knockout rescues degradation. Repurposed telmisartan directly inhibits Kdm5c, blocking this axis and showing disease‐modifying efficacy in mouse OA models

Preliminary analysis of the Late Natufian ground stone from Shubayqa 1, Jordan

open access: yesJournal of Lithic Studies, 2016
Shubayqa 1 is a newly identified early and late Natufian site in the harra desert of northeastern Jordan. In addition to buildings, and rich chipped stone, faunal, and botanical assemblages, the site has produced a large collection of ground stone tools.

Facile Fabrication of Low‐Impedance, Highly Conformal Epidermal Electrodes Based on Laser‐Induced Graphene–Silver Nanocomposites

open access: yesAdvanced Science, EarlyView.
A facile laser‐induced graphene–silver nanocomposite strategy enables ultrathin epidermal electrodes with low impedance, high conductivity, and excellent mechanical robustness. The porous LIG–Ag conductive network mechanically interlocked with SEBS provides stable, motion‐resistant biopotential monitoring, enabling high‐fidelity ECG, EMG, and EEG ...

Beyond Potency: Emerging Determinants and Optimization Strategies Enhancing Therapeutic Efficacy of Adult Stem Cells

open access: yesAdvanced Science, EarlyView.
Adult stem cell therapy requires more than high in vitro potency. This review proposes a systems framework in which cell‐intrinsic programs, instructive microenvironmental cues, and pre‐/post‐delivery engineering are co‐designed under standardized translational rules.

Aşezarea tripoliană tardivă de lângă satul Voloviţa (raionul Soroca, Republica Moldova) / Late Tripolian settlement near the village of Voloviţa (Soroca District, Republic of Moldova)

open access: yesTyragetia, 2014
The article publishes the materials from the surface of a new Late Tripolian settlement in the Middle Dniester region. Apart from pottery, the abundance of stone implements is quite remarkable.

Evidence of daily life inside the EBA I defence system at Hacılar Büyük Höyük (Burdur–Turkey)

open access: yesБългарско е-Списание за Археология, 2021
Excavations at Hacılar Büyük Höyük, which is located 27 km to the southwest of Burdur, began in 2011 under my direction and are still in progress. The pre-planned, “sawtooth”-shaped defence system surrounds the settlement along the western slope like a ...

Quality Thresholds for Angiogenesis Under Acoustic Manipulation in Engineered Vascular Tissues

open access: yesAdvanced Science, EarlyView.
Defined biological and physical quality thresholds achieved through acoustic manipulation regulate cellular alignment and spatial organization, promoting self‐assembling vasculature, extracellular matrix deposition, and angiogenic responses, thereby establishing critical acoustic patterning requirements for engineered vascular tissue development in ...

Halide Perovskite: A Rich Source of Thermal Insulator

open access: yesAdvanced Science, EarlyView.
Halide perovskites exhibit ultralow thermal conductivity driven by intrinsic lattice softness and strong anharmonicity, falling below conventional defect‐engineering limits. Weak metavalent bonding, A‐site rattling, and dynamic octahedral tilting drive phonon scattering to the Ioffe–Regel limit, where wave‐like tunneling replaces particle‐like ...

The Cretan Mesolithic in context: new data from Livari Skiadi (SE Crete)

open access: yesDocumenta Praehistorica, 2016
Investigations at Livari (south-eastern Crete) produced a small Mesolithic chipped stone assemblage, whose techno-typological characteristics situate it within an ‘early Holocene Aegean island lithic tradition’ (9000–7000 cal BC).

Chipped Stone Assemblage

open access: yesScottish Archaeological Internet Reports
At North Barr River, Morvern, inspection of forestry planting mounds on a raised beach terrace identified a chipped stone assemblage associated with upcast deposits containing charcoal. An archaeological evaluation of the site, funded by Forestry Commission Scotland, sought to better understand the extent and character of this Mesolithic and later ...
