Cost‐Effective Hierarchical Cobalt Nanostructured Laser‐Induced Graphene for Enhanced Uric Acid Detection

Advanced Sensor Research, EarlyView.
A one‐step electrochemical strategy is utilized to develop a flexible, enzyme‐free biosensor for the sensitive detection of uric acid (UA). The hierarchical cobalt nanostructures synergistically enhance the performance of the biosensor, resulting in a broad detection range of 5 to 700 µM with a sensitivity of 6.75 µA µM−1 cm−2 and a low detection limit

Overexpression of ameloblastin in secretory ameloblasts results in demarcated, hypomineralized opacities in enamel

Frontiers in Physiology
Introduction: Developmental defects of the enamel manifest before tooth eruption and include amelogenesis imperfecta, a rare disease of underlying gene mutations, and molar–incisor hypomineralization (MIH), a prevalent disease in children originating ...

Atomic-scale compositional mapping reveals Mg-rich amorphous calcium phosphate in human dental enamel

Science Advances, 2016
Atomic-scale study of human dental enamel reveals an intergranular amorphous phase thought to be responsible for tooth decay. Human dental enamel, the hardest tissue in the body, plays a vital role in protecting teeth from wear as a result of daily ...

Role of the Setae in an Ectoparasitic Seal Louse in Reducing Surface Drag: Numerical Modeling Approach

Advanced Theory and Simulations, EarlyView.
The seal louse Echinophthirius horridus has uniquely shaped setae that may reduce drag during its host's dives. Using numerical simulations, this study demonstrates that their natural inclination promotes vortex formation, minimizing friction and energy loss. These findings provide insights into biological surface adaptations and may inspire the design

Testing a quick and reliable method to discriminate age classes in roe deer <em>Capreolus capreolus</em> on the basis of tooth wear

Hystrix, the Italian Journal of Mammalogy, 2000
<strong>Abstract</strong> The hunting management of roe deer in Emilia-Romagna provides the correct classification of the age classes of dead specimens, usually determined shortly after killing by hunters.

Oriented and Ordered Biomimetic Remineralization of the Surface of Demineralized Dental Enamel Using HAP@ACP Nanoparticles Guided by Glycine

Scientific Reports, 2017
Achieving oriented and ordered remineralization on the surface of demineralized dental enamel, thereby restoring the satisfactory mechanical properties approaching those of sound enamel, is still a challenge for dentists.

M2 Macrophage‐Derived Extracellular Vesicles Reprogram Immature Neutrophils into Anxa1hi Neutrophils to Enhance Inflamed Bone Regeneration

Advanced Science, EarlyView.
This study reveals that M2‐EVs mitigate periodontitis‐induced bone resorption by modulating neutrophil fate. Single‐cell RNA sequencing identified an Anxa1hi neutrophil subpopulation with pro‐reparative properties. M2‐EVs disrupt neutrophil maturation, promoting this subpopulation through key reprogramming genes (Acvrl1, Fpr2). These findings highlight

Polyaspartic Acid‐Calcium‐Lanthanum Complexes Induce Antibacterial Remineralization of Dentin and In‐Depth Occlusion of Dentinal Tubules

Advanced Science, EarlyView.
Polyaspartic acid‐calcium‐lanthanum (PAsp‐Ca‐La) complexes could induce antibacterial remineralization of demineralized dentin and in‐depth occlusion of dentinal tubules (DTs) with lanthanum‐doped hydroxyapatite (La‐HAp) via polyelectrolyte‐cation complexes pre‐precursor (PCCP) process, allowing the release of La3+ in response to acids generated by ...
