Toward Wireless Implantable Robotic Systems Driven by Magnetic Field for Personalized Therapy

Advanced Robotics Research, EarlyView.
Robotic materials are playing an increasingly vital role in enabling sensing and actuation at small scales. This perspective highlights recent advances in magnetic materials and magnetically actuated devices for wireless sensing, actuation, and energy harvesting toward implantable robotic systems for closed‐loop therapy.

ROS Activated NETosis of Bone Marrow CD55+ Intermediate Mature Neutrophils Through HIF1α‐PADI4 Pathway to Initiate Bone Aging

Advanced Science, EarlyView.
In this study, we find CD55+ neutrophils show activated NETosis within bone marrow, induce BMSC senescence and osteogenesis inhibition, finally leading to bone aging initiation. Mechanistically, ROS synergizes with the CD55‐driven HIF1α‐PADI4 pathway to promote NETosis.

EFECTO DE DIFERENTES MÉTODOS DE LIMPIEZA EN MATERIALES PARA PRÓTESIS DENTALES REMOVIBLES

, 2018
The purpose of this study is to evaluate the effects of different cleaners on the surfaces of removable dental prostheses. Two different prosthetic materials (acrylic resin and polyamide) were subjected to various cleaning methods and subsequently analyzed with a roughness tester and observed with the scanning electron microscope (SEM).

Midbrain PAG Astrocytes Modulate Mouse Defensive and Panic‐Like Behaviors

Advanced Science, EarlyView.
Astrocytes in the midbrain periaqueductal gray (PAG) dynamically encode threat intensity and shape defensive action selection in mice. Real‐time Ca2+ imaging reveals robust astrocytic activation during predator odor and CO2 exposure. Aberrant astrocytic Ca2+ overactivation disrupts goal‐directed escape, biases behavior toward freezing, and induces ...

DEL‐1 is an Endogenous Senolytic Protein that Inhibits Senescence‐Associated Bone Loss

Advanced Science, EarlyView.
Senescent bone marrow stromal cells accumulate in the aging bone microenvironment, promoting bone degeneration. DEL‐1, an endogenous secreted protein, acts as a natural senolytic that selectively eliminates these cells. By engaging a β3 integrin/CD73/adenosine/p38 MAPK/BCL‐2 pathway, DEL‐1 counters aging‐related bone loss, revealing promising ...
