Assessment of smartphone-based active distraction in association with audioanalgesia for overcoming airotor-related anxiety in children: a randomized controlled trial.
BMC Res Notes

Manipal Academy of Higher Education, Manipal, Karnataka, India.
Background: Most children experience distress while visiting a dentist, above which the sound of the airotor and suction machine results in fear and difficulty in performing further procedures.
Methods: This was a randomized controlled parallel-group study of 40 children aged 6-13 years who required cavity preparation via the airotor. The children were randomly allocated to either Group 1 (Piano music app; active distraction combined with audio analgesia) or Group 2 (basic behavioural guidance alone).

Objectives: Previous studies reported various methods of measuring fracture toughness of dental ceramics. The objectives of this study were to compare different methods and to validate fractal analysis to estimate fracture toughness for a polycrystalline dental ceramic.
Methods: Bar-shaped specimens were prepared from 3 mol% yttria-stabilized tetragonal polycrystalline (3Y-TZP) ceramic.

The application of hydrogels to drug delivery limited by the difficulty of encapsulating hydrophobic drugs; therefore, the development of novel composite hydrogels for the delivery of hydrophobic drugs is urgently needed. In this study, terbinafine hydrochloride/hydroxypropyl-β-cyclodextrin inclusion complexes (TFH/HP-β-CD ICs) were added to a Schiff base hydrogel matrix containing octenyl succinic anhydride-modified chitosan (OSA-CS) and sodium alginate (OIA) to prepare a TFH composite hydrogel (TFH GEL). The results revealed that the solubility of TFH in water within TFH/HP-β-CD IC reached 32.

The COVID-19 pandemic has revealed the need for nations to prepare more effectively for emerging infectious diseases. Preparing for these threats requires a multifaceted approach that includes assessing pathogen threat, building flexible capabilities for rapid medical countermeasure (MCM) development, and exercising, maintaining, and improving those response capabilities. The Biomedical Advanced Research and Development Authority (BARDA) promotes the advanced development of MCMs in response to natural and manmade threats.

Atherosclerosis (AS) is a chronic inflammatory disease characterized by vascular endothelial dysfunction. In the early stage of the disease, endothelial cell injury induces the infiltration of inflammatory macrophages, which secrete large amounts of inflammatory factors, further aggravating endothelial cell dysfunction and exacerbating the disease. Therefore, it is promising for co-targeting endothelial cells and macrophages further regulating the inflammatory microenvironment and endothelial cell function for effective treatment.
