PIAS3 CircRNA‐Loaded Lipid Nanoparticles Restore ALOX15 SUMOylation to Suppress Cementoblast Ferroptosis and Attenuate Orthodontically Induced Root Resorption

Advanced Science, EarlyView.
Orthodontic compression suppresses PIAS3 expression in cementoblasts, impairing ALOX15 SUMOylation and ubiquitin‐mediated degradation, which leads to ALOX15 accumulation, lipid peroxidation, ferroptosis, and osteoclastogenesis. Local delivery of PIAS3 circRNA‐loaded lipid nanoparticles restores the PIAS3–ALOX15 regulatory pathway, alleviates ...

Initial arch wires used in orthodontic treatment with fixed appliances [PDF]

Cochrane Database of Systematic Reviews, 2018
Initial arch wires are the first arch wires inserted into fixed appliance at the beginning of orthodontic treatment. With a number of different types of orthodontic arch wires available for initial tooth alignment, it is important to understand which are most efficient and which cause the least amount of root resorption and pain during the initial ...

A self‐retaining mouth prop for intraoral access during periodontal surgery in rat models: A technical note

Animal Models and Experimental Medicine, EarlyView.
A mouth prop designed to mimic the oral cavity of rats was made that provided stable, self‐retaining retraction, thereby facilitating oral surgery on rodents. Compared to conventional methods, it decreased surgical time, operator fatigue, and slippage. Its use led to higher efficiency and fewer complications and it was cost effective to produce.

Biomimetic Nanomedicine for Aging‐Impaired Bone Regeneration: From Microenvironmental Dysfunction to Precision Therapeutics

Advanced NanoBiomed Research, EarlyView.
Aging disrupts the cellular, immune, vascular, and neural processes required for bone regeneration. This review connects these pathological barriers with biomimetic nanomedicine design, highlighting strategies for cellular rejuvenation, immune modulation, vascular regeneration, and neuro–bone coupling.

Cortical bone distribution in the human mandibular symphysis: Ontogenic and morphometric approaches in archeological context

The Anatomical Record, EarlyView.
Abstract The human mandibular symphysis concentrates multiaxial loads during function and remodels throughout growth, but the precise mechanisms underlying cortical bone shape during growth remain relatively unexplored. Approaches based solely on thickness or external cortical contours provide only partial insights and do not capture the functional ...
