Preclinical Toxicity Screening of Sodium Dodecanoyloxybenzenesulfonate (LOBS) as a New Alternative Biocide Using In Vitro and In Vivo Models

Environmental Toxicology, EarlyView.
ABSTRACT Sodium hypochlorite is a well‐established biocide extensively used in both living and industrial environments; however, exposure to it or improper handling can harm the human body and the environment. Thus, safer alternatives to sodium hypochlorite are required.

Cyanopeptide Mixtures Induce Variable Synergistic and Antagonistic Effects Across Diverse Human Cell Lines

Environmental Toxicology, EarlyView.
ABSTRACT Cyanobacterial harmful algal blooms (cyanoHABs) threaten human, animal, and ecosystem health and safety through production of toxic secondary metabolites. Microcystis, a cosmopolitan bloom‐forming cyanobacterial genus, is well‐known for producing hepatotoxic microcystins (MCs), but it can produce many other bioactive cyanopeptides, such as ...

Surface Micro‐Discharge Plasma for Multiple Teeth Bleaching: Efficacy, Mechanism and Safety

High Voltage, EarlyView.
ABSTRACT Hydrogen peroxide (H2O2) is the commonly‐used bleaching chemical in clinical practice, but its excessive concentrations can cause tooth damage. Atmospheric pressure cold plasma is considered a promising new technique for tooth bleaching. Surface micro‐discharge (SMD) devices can generate large‐scale plasma, which holds potential for treating ...
