Orthodontically induced root resorption (OIRR) is a common side effect during orthodontic tooth treatment (OTM). The function of osteoprotegerin (OPG) is considered to protect cementum from excessive resorption to maintain root integrity. In this study, we observed that the expression of TGF-β1 and OPG was upregulated under the loading of orthodontic force in periodontal tissues.

Article Synopsis
  • - The study focused on understanding risk factors associated with the distal adding-on phenomenon in adolescent idiopathic scoliosis (AIS) patients specifically classified as Lenke 1A/B and 2A/B, and aimed to create a prediction model for this condition.
  • - Researchers analyzed clinical data from 119 AIS patients, assessing radiographic parameters before surgery and at the last follow-up, identifying 39 patients (32.8%) who experienced the adding-on phenomenon.
  • - A logistic regression analysis revealed five significant predictive variables, including the Risser sign, leading to the development of a reliable nomogram that can help predict the occurrence of adding-on and inform better clinical treatment strategies.

Background: Intact cementum is vital for tooth stability and health. Cementoblasts, which line the root surface, are responsible for cementum formation. Recent evidence suggests that circular RNAs (circRNAs) are involved in various cellular functions and may have clinical applications.

The proliferation and mineralization of preosteoblasts is crucial for bone formation and has attracted extensive attentions for decades. However, the roles of numerous long non-coding RNAs (lncRNAs) in preosteoblasts have not been fully determined. This study aimed to investigate the function of lncRNA Snhg15 in preosteoblasts as well as the potential underlying mechanism.

Titanium alloys represent the prevailing material employed in orthopedic implants, which are present in millions of patients worldwide. The prolonged presence of these implants in the human body has raised concerns about possible health effects. This study presents a comprehensive analysis of titanium implants and surrounding tissue samples obtained from patients who underwent revision surgery for therapeutic reasons.

Article Synopsis
  • This study compares the effectiveness of two surgical methods for removing hemivertebrae in children with congenital scoliosis: total hemivertebra resection (TR) and partial hemivertebra resection (PR).
  • Conducted from 2011 to 2016, the research involved 43 young patients, with no significant differences in the correction of spinal curvature (Cobb angle) between the two techniques after surgery and at follow-up.
  • The findings suggest that partial hemivertebra resection is a safe and efficient alternative to total resection, but further long-term outcomes need to be evaluated as the patients grow.

Objective: As there are no substantial selection criteria for determining the lowest instrumented vertebra (LIV) in adolescent idiopathic scoliosis (AIS) Lenke 5C/6C, thus, many surgeons base their selection on experience. The study aims to compare the selection of the lowest instrumented vertebrae (LIV) lumbar vertebra three (L3) with the use of direct vertebrae rotation (DVR) to the lowest instrumented vertebrae (LIV) lumbar vertebra four (L4) with the use of non-DVR for the correction of adolescent idiopathic scoliosis (AIS) Lenke 5C/6C when the lower end vertebrae (LEV) is at lumbar vertebrae four (L4).

Methods: This prospective study involved 101 patients who were divided into two groups based on different techniques.

Cobalt alloys have numerous applications, especially as critical components in orthopedic biomedical implants. However, recent investigations have revealed potential hazards associated with the release of nanoparticles from cobalt-based implants during implantation. This can lead to their accumulation and migration within the body, resulting in adverse reactions such as organ toxicity.

Background: The fat mass and obesity-associated protein (FTO) is an RNA demethylase that contributes to several physiological processes. Nonetheless, the impact of FTO on bone remodeling in the midpalatal suture while undergoing rapid maxillary expansion (RME) remains unclear.

Methods: First, to explore the expression of FTO in the midpalatal suture during RME, six rats were randomly divided into two groups: Expansion group and Sham group (springs without being activated).

Optically readable organic synaptic devices have great potential in both artificial intelligence and photonic neuromorphic computing. Herein, a novel optically readable organic electrochemical synaptic transistor (OR-OEST) strategy is first proposed. The electrochemical doping mechanism of the device was systematically investigated, and the basic biological synaptic behaviors that can be read by optical means are successfully achieved.

Introduction: Vaccination is one of the most effective ways to control the COVID-19 pandemic. However, as the number of people vaccinated against COVID-19 continues to increase, there are more reports on the safety of vaccines. So far, there have been no reported cases of spinal infection associated with COVID-19 vaccination.

Background: An Andersson lesion (AL) is a fatigue fracture occurring across three columns in ankylosing spondylitis (AS), resulting in spinal pseudarthrosis (SP) formation, most commonly in the thoracolumbar segment. However, there is still great controversy and few reports on the best surgical method for the treatment of AS combined with thoracolumbar AL. The purpose of this study was to investigate the efficacy of posterior closed osteotomy, debridement and fusion through the fracture line for the treatment of this disease.

Simulation of biological visual perception has gained considerable attention. In this paper, an optoelectrical InO transistor array with a negative photoconductivity behavior is designed using a side-gate structure and a screen-printed ion-gel as the gate insulator. This paper is the first to observe a negative photoconductivity in electrolyte-gated oxide devices.
