Background: The prevention of healthcare-associated infections requires continuous effort. In order to achieve better practical results, the control of environmental microbial biofilms with effective disinfection strategies should be addressed.
Aim: To test the efficacy of different time cycles of nebulized hydrogen peroxide (HO) against bacterial and yeast dry biofilms.
Methods: The efficacies of a standard cycle (SC) and a fast cycle (FC) of nebulized HO were compared. Microbial biofilms were grown on different material coupons. The metabolic activity of biofilms was determined by XTT assay, and the total biomass of biofilms was determined by crystal violet assay.
Findings: Regarding the efficacy of nebulized HO against biofilms, the mean reduction in metabolic activity for the SC was 55.2% [standard deviation (SD) 19.4%], compared with 50.4% (SD 17.7%) for the FC. The mean reduction in total biomass for the SC was 45.5% (SD 22.7%), compared with 46.7% (SD 21.7%) for the FC. No significant differences were found between the tested cycles and materials.
Conclusion: HO nebulization was found to exhibit good efficacy against healthcare-associated microbial dry biofilms. Moreover, similar efficacies were found between the SC and the FC.

The increasing prevalence of neurodegenerative diseases is a formidable task due to their multifactorial causation and treatments limited to disease maintenance and progression. Epstein-Barr virus (EBV) is reported to be involved with neuropathologies; previous studies from our group suggested the effective binding of epigallocatechin-3-gallate (EGCG) with EBV nuclear antigen 1 (EBNA1) and glycoprotein H (gH). Therefore, in the current study, we evaluated the anti-EBV effect of ECGG on the neuronal cells.

Mismatched nucleobase uracil is commonly repaired through the base excision repair initiated by DNA uracil glycosylases. The data presented in this study strongly indicate that the nuclear uracil-N-glycosylase activity and nuclear protein content in human cell lines is highest in the S phase of the cell cycle and that its distribution kinetics partially reflect the DNA replication activity in replication foci. In this respect, the data demonstrate structural changes of the replication focus related to the uracil-N-glycosylase distribution several dozens of minutes before end of its replication.

Background: Limited data are available on the global rates of paediatric multiple sclerosis. Here, we report on the estimated worldwide prevalence of paediatric MS.
Methods: We included paediatric prevalence data in 2020-2022 (Multiple Sclerosis International Federation Atlas of MS) and the prevalence of child neurologists (International Child Neurology Association).

Per- and polyfluoroalkyl substances (PFAS), also known as "forever chemicals" because of their persistence in the environment, have been used in many commercial applications since the 1940s. Of late, the detection of PFAS in drinking water throughout the United States has raised public and scientific concerns. To understand PFAS exposure trends in the general U.
