Aim: Purpose of this in-vitro study was to assess and compare the antimicrobial activity of three different glass ionomer cements (GIC) against streptococcus mutans (S. mutans) bacteria using agar plate diffusion test.
Methods: Thirty blood agar plates were prepared and three wells of 4mm diameter were made on each agar plate. Three different GIC (Micron bioactive, GC Fuji IX GP Extra, Bioglass r) were mixed and filled into the wells. These plates were inoculated with S. Mutans and incubated at 37°C for 24 hours. Bacterial growth inhibition zone around each well were recorded in millimeters using Hiantibiotic Zonescale-C.
Result: All the restorative material used in the study exhibited antimicrobial property against S. Mutans. GC Fuji IX GP Extra showed superior antimicrobial efficacy with 17.3±2.6 mm mean diameter of bacterial inhibition zone, followed by Micron bioactive 14.4±1.07 mm and Bioglass r 10.8 ± .91 mm inhibition zone respectively.
Conclusion: Within the limitation of this study, it can be concluded that all the GIC evaluated demonstrated antibacterial activity against S. mutans. The superior antimicrobial activity was demonstrated by GC Fuji IX GP Extra. Hence, it could be advantageous in patients with high caries risk.

Objective: Identification of seizure focus on the interhemispheric fissure (IHF) is often challenging at the step of scalp video-EEG monitoring on preoperative evaluations. We previously reported ictal three-phase EEG patterns (3Ph-EEG) and isolated eye deviation (isolated ED) to side of the seizure focus during seizures, each of which is available for identifying the seizure focus for frontal IHF (F-IHF). This study aimed to evaluate the accuracy of predicting the F-IHF focus using a combination of 3Ph-EEG and isolated ED in patients with frontal lobe epilepsy and the accuracy of predicting lateralization of the F-IHF focus using the predominance of findings.

Background: Low mechanical properties are the main limitation of glass ionomer cements (GICs). The incorporation of elastomeric micelles is expected to enhance the strength of GICs without detrimentally affecting their physical properties and biocompatibility. This study compared the chemical and mechanical properties, as well as the cytotoxicity, of elastomeric micelles-containing glass ionomer cement (DeltaFil, DT) with commonly used materials, including EQUIA Forte Fil (EF), Fuji IX GP Extra (F9), and Ketac Molar (KT).

Purpose: To evaluate and compare the laboratory compressive strength (CS), flexural strength (FS), and diametral tensile strength (DTS) of Cention Forte and three bulk fill restorative materials.
Methods: A total of 168 specimens were prepared following the manufacturers' instructions and standards for testing CS, FS, and DTS. Mechanical properties of Cention Forte (LC-Cent) were compared to three commercial bulk-fill materials for posterior restorations: Fuji IX Extra (Fuji), Tetric PowerFill (TPF), and Equia Forte HT (Equia).
Low-density lipoprotein cholesterol, erythrocyte, and platelet in heart failure with preserved ejection fraction.

Article Synopsis
- The study investigates how low LDL cholesterol, anemia, and low platelet levels affect outcomes in heart failure patients with preserved ejection fraction (HFpEF).
- Using data from 1021 hospitalized patients, they created a scoring system (LEP score) to evaluate the risk of all-cause death and heart failure readmission based on these factors.
- The findings showed that higher LEP scores correlated with an increased risk of negative outcomes, highlighting the importance of monitoring these three components in managing HFpEF patients.
