Objectives: The aim of this study is to investigate the effect of electrical heat carrier temperature on bacterial leakage of root canals obturated with the continuous wave of condensation (CWC) technique and a bioceramic sealer.
Methods: This ex vivo experimental study was conducted on 92 extracted single-rooted teeth. The teeth were subjected to endodontic treatment and obturated with the Endoseal MTA bioceramic sealer by the CWC technique using two different temperature settings of the electrical heat carrier: 120°C (group G120, n = 41) and 200°C (group G200, n = 41). A positive and a negative control group were also considered (n = 5 each). Bacterial leakage was assessed over a 40-day period using a bacterial leakage model. The incidence of bacterial leakage was compared between the experimental groups using the log-rank test. The significance level was set at 0.05.
Results: The median survival rate was 39.0 (25.0) days in the G120 group and 34.0 (25.0) days in the G200 group. Despite a slightly higher survival rate in the G120 group, the difference between the two experimental groups was not statistically significant (p = 0.612).
Conclusion: The tested temperatures of the electrical heat carrier (120°C and 200°C) did not have a significant effect on bacterial leakage of root canals obturated by the CWC technique and the Endoseal MTA bioceramic sealer.

The rise of multidrug-resistant (MDR) bacteria in food products poses a significant threat to public health, necessitating innovative and sustainable antimicrobial solutions. This study investigates the green synthesis of zinc oxide nanoparticles (ZnO-NPs) using extracts to evaluate their antibacterial and antibiofilm activities against MDR strains isolated from sold fish samples. The obtained results show that the contamination with reached 54.

Background: Progressive familial intrahepatic cholestasis type 1 (PFIC-1) is a genetic cholestatic disease causing end-stage liver disease, which needs liver transplantation (LT). Simultaneous biliary diversion (BD) was recommended to prevent allograft steatosis after transplantation, while increasing the risk of infection. Here, an attempt was made to perform BD using appendix to prevent bacterial translocation after LT.

New s-triazine hydrazone hybrids (4a-4r) were designed and synthesized as promising microbial DNA gyrase inhibitors. This was done by taking the lead DNA gyrase inhibitor (AstraZeneca arylaminotriazine) as a reference. The novel samples were subsequently tested as antimicrobial agents against certain pathogenic bacteria and unicellular fungi.

This study thoroughly explores the synthesis, characterization, and antimicrobial efficacy of three α-aminophosphonate-chitosan (α-AP-Cs) compounds and their nano‑silver functionalized organic hybrids. α-AP-Cs derivatives (CU, CT and CSC) were synthesized via an in-situ, one-pot reaction using chitosan and triphenyl-phosphite, with different carbamide-glutaraldehyde crosslinkers; urea-glutaraldehyde, thiourea-glutaraldehyde and semicarbazide-glutaraldehyde, respectively. Subsequently, their corresponding α-AP-Cs‑silver nanocomposites (CU-AgNPs, CT-AgNPs and CSC-AgNPs) were synthesized via solid-state approach.

1,2-Benzisothiazol-3(2H)-one (BIT) has strong antibacterial activity, but its water insolubility and skin toxicity effects hinder its application in the antibacterial domain of the fuel system. In this study, benzisothiazolinone quaternized chitosan derivative (HACCBIT) was synthesized by intercalated quaternized chitosan with 1,2-benzisothiazolin-3-one-based anions (BIT-COO-) via ion-exchange reactions. HACCBIT exhibits enhanced aqueous solubility and remarkable biocompatibility.
