Filler found in bone: Surgical removal of polyacrylamide hydrogel (Amazingel) from the mandible after 24 years: A case report and literature review.

Polyacrylamide hydrogel (PAAG) is widely regarded as a safe soft tissue filler and has been extensively utilized for cosmetic enhancements, such as breast and facial augmentation in China from 1997 until its ban in 2006. Common complications associated with its use include inflammation, infection, granulomas, fibrosis, gel migration, and facial and soft tissue deformities. This case report describes a 45-year-old Chinese woman who experienced PAAG migration into her mandible 24 years after facial augmentation, causing irritation of the mandibular alveolar nerve - apparently the first documented instance of this occurrence.

Exploring the use of ChatGPT/GPT-4 for patient follow-up after oral surgeries.

Since 2023, ChatGPT has been leading a research boom in large language models. Research on the applications of large language models in various fields is also being explored. The aim of this study was to explore the use of ChatGPT/GPT-4 for post-surgery patient follow-up after oral surgery.

Adipose-derived mesenchymal stem cells (MSCs) are a superior cell source for bone tissue engineering.

Effective bone regeneration through tissue engineering requires a combination of osteogenic progenitors, osteoinductive biofactors and biocompatible scaffold materials. Mesenchymal stem cells (MSCs) represent the most promising seed cells for bone tissue engineering. As multipotent stem cells that can self-renew and differentiate into multiple lineages including bone and fat, MSCs can be isolated from numerous tissues and exhibit varied differentiation potential.

Modeling lung diseases using reversibly immortalized mouse pulmonary alveolar type 2 cells (imPAC2).

Background: A healthy alveolar epithelium is critical to the gas exchange function of the lungs. As the major cell type of alveolar epithelium, alveolar type 2 (AT2) cells play a critical role in maintaining pulmonary homeostasis by serving as alveolar progenitors during lung injury, inflammation, and repair. Dysregulation of AT2 cells may lead to the development of acute and chronic lung diseases and cancer.

Oral transmucosal absorption of iodine after intraoral preparation with povidone-iodine prior to oral surgeries: a randomized controlled study in 12 male patients.

Introduction: Absorption of iodine through skin and an increased incidence of thyroid disorders due to iodophor exposure are reported. However, the risk of oral transmucosal absorption of povidone-iodine after intraoral preparation is not clear.

Objective: To investigate the possibility of oral transmucosal absorption of povidone-iodine after intraoral preparation and its effect on thyroxine level in blood.

Canonical Wnt signaling regulates branching morphogenesis of submandibular gland by modulating levels of lama5.

Branching morphogenesis is a crucial developmental mechanism for the formation of the typical bush-like structure of the submandibular gland (SMG). However, the detailed mechanism underlying this process remains to be fully understood. Here, we have investigated whether cross-talk may exist between the Wnt/beta-catenin signaling pathway and lama5 during the branching process in SMG development.

DnaJ (hsp40) of Streptococcus pneumoniae is involved in bacterial virulence and elicits a strong natural immune reaction via PI3K/JNK.

As a heat shock protein, DnaJ plays an important role in the pathogenesis of pneumococcal infection. However, how the virulence factor-DnaJ elicits host natural immunity still remains unclear. In this study, we investigated the effects of dnaJ deficiency in Streptococcus pneumoniae (S.

[A long-term evaluation of bibuccinator myomucosal island flap applying to elder patients suffered from wide cleft palate].

Objective: To evaluate a long-term effect on pronunciation and maxillary growth of elder patients with wide isolated cleft palate after bibuccinator myomucosal island flap palatoplasty.

Methods: Twelve patients over eight years old with wide isolated cleft palate were selected in experiment group, who received bibuccinator myomucosal island flap palatoplasty. The common group comprised 20 age-matched patients with isolated cleft palate receiving traditional palatoplasty named double-flap method.

[Influence of propofol and isoflurane on cytokines response to cancer surgery during perioperative period].

Objective: To compare the influence of propofol and isoflurane on pro-inflammatory and anti-inflammatory cytokine response to perioperative period of tongue cancer surgery.

Methods: Twenty-four adult patients undergone the operation of tongue cancer were assigned to two groups randomly, propofol group (Group P) and isoflurane group (Group I). In group P, anesthesia was induced with fentanyl 2-3 microg/kg, propofol 2 mg/kg, atracurium 0.
