Human Bone‐Derived Endothelial Cells Mediate Bone Regeneration via Distinct Expression of KIT Ligand

Advanced Science, EarlyView.
Bone‐specific endothelial cells (b‐ECs) uniquely express KITLG, which recruits c‐Kit+/CD34+ hematopoietic progenitors (HPCs) to the osteovascular niche, initiating a cascade that culminates in the osteogenic differentiation of bone marrow‐derived mesenchymal stem cells (bm‐MSCs) and subsequent ossification.

Cellular Adaptation to Mechanical Stress Emerges via Cell Shrinkage Triggered by Nonlinear Calcium Elevation

Advanced Science, EarlyView.
Here, a decision‐making mechanism underlying mechanical adaptation is demonstrated. This study demonstrates that cellular adaptation to mechanical stress can be induced by applying low‐amplitude stretch to cells. When the stretch reaches a critical amplitude threshold, it triggers Ca2⁺‐dependent positive feedback, which induces cholesterol efflux and ...

Adjunctive Orthodontic Treatment with Lingual Orthodontic System

Kathmandu University Medical Journal, 2012
The lingual orthodontic therapy though started in 1972, could not be popular till the beginning of 1990. In Nepal it does not have a history of more than a year. It is started in Dhulikhel Hospital for the first time in Nepal. Usually orthodontic therapy is meant for putting braces on the labial surface of the teeth which is called labial orthodontic ...

Additive Manufactured Magnetoelectric Wireless Retainer as the Periodontal Remodeler for Post‐Orthodontic Tissue Reconstruction and Relapse‐Inhibition

Advanced Science, EarlyView.
Orthodontic relapse persists as a 120‐year challenge, as traditional retainers fail to remodel tissue, causing lifelong dependence. This study demonstrates a flexible magnetoelectric retainer (FMOR) enabling wireless periodontal remodeling. FMOR cues shift periodontal ligament cell (PDLC) paracrine signaling, promoting M2 macrophages, osteogenic ...

Er:YAG laser, piezosurgery, and surgical drill for bone decortication during orthodontic mini-implant insertion: primary stability analysis-an animal study [PDF]

, 2017
It is important to identify factors that affect primary stability of orthodontic mini-implants because it determines the success of treatment. We assessed mini-implant primary stability (initial mechanical engagement with the bone) placed in pig jaws. We
