Article Synopsis
- * A study compared two training models—the Blue Phantom and NeedleTrainer—with 47 novice participants, assessing their performance and feedback on both simulators.
- * Results showed that while the Blue Phantom had longer time-to-target, it provided a 100% success rate and lower complications, contributing to higher learning satisfaction and confidence compared to the NeedleTrainer.
Introduction: The MERIT study in Malaysia is a real-world retrospective, observational, multicenter study that evaluated asthma control in patients with uncontrolled asthma who were switched from as-needed (pro re nata [PRN]) budesonide/formoterol or inhaled corticosteroid (ICS) whenever a short-acting beta-agonist (SABA) was taken, to proactive regular dosing of fluticasone propionate/salmeterol (FP/SAL PRD).
Methods: Data from the medical records of patients who were stepped up to FP/SAL PRD were extracted retrospectively at baseline and follow-up (between 3 and 6 months after stepping up to FP/SAL PRD). The primary endpoint was the percentage of patients with improvement in asthma control assessed via the Asthma Control Test (ACT).
Objective: Leaching of particles from dental titanium implant surfaces into preimplant microenvironment causes detrimental effects on bone cells. The current study investigated influence of simvastatin in mitigating adverse pro-inflammatory effects of titanium dioxide (TiO) micro (MP) and nano (NP) particles on hFOB 1.19 cells in vitro.

This study aimed to develop a porous polycaprolactone (PCL) membrane incorporated with 25 wt % Vitamin C (PCL-Vit C) and compared it to the PCL membrane to control oxidative stress and enhance biomineralization Both membranes were characterized using SEM-EDS, FTIR spectroscopy, and surface hydrophilicity. Vitamin C release was quantified colorimetrically.

Materials And Methods: Different concentrations of titanium dioxide nano- and micro-particles were prepared and their biocompatibility on HOBs was analyzed using XTT assay. The changes in the actin cytoskeletal organization were studied by confocal laser scanning microscopy.
