On‐site pilot‐scale advanced oxidation pretreatment of hospital wastewater: assessment of pharmaceuticals, pathogens, antibiotic resistance genes and acute ecotoxicity

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Hospital premises generate wastewater containing a wide spectrum of contaminants, such as pharmaceutically active compounds (PhACs), antibiotic resistance genes (ARGs) and pathogenic microorganisms, whilst plenty of them are classified under the antibiotic resistant bacteria (ΑRΒ) category.

Assessment of Thyroid Uptake Ratio Values in a Normal Population. Establishment of Normal Reference Values for 99mTc‐Pertechnetate Thyroid Uptake in an Australian Population

Journal of Medical Radiation Sciences, EarlyView.
An Australian first, this study examined normal reference ranges for 99mTc‐pertechnetate thyroid uptake. Through a retrospective and prospective analysis, this study found a new reference range of 0.4%–2.4%. The findings suggest that locally derived reference values may differ from historical data and highlight the importance of region‐specific ...

The effect of non‐surgical periodontal treatment on progranulin levels

Journal of Periodontology, EarlyView.
Abstract Background The aim of this study was to study the effect of non‐surgical periodontal therapy (NSPT) on gingival crevicular fluid (GCF) and serum progranulin (PGRN) levels in the early healing phases. Methods The study included periodontitis (test) (n = 24) and periodontal health (control) (n = 24) groups.

Electrolyzed saline as an alternative to chlorhexidine: Antimicrobial and biofilm volume outcomes in a 4‐day non‐brushing randomized controlled clinical trial

Journal of Periodontology, EarlyView.
Abstract Background The biofilm‐inhibitory effects of electrolyzed saline (EOS) vary widely due to differences in formulations and treatment methods. This study analyzed the impact of EOS on key oral microbial species and used serial 3D‐intraoral scans to evaluate its effects on de novo biofilm formation.

Research progress of disinfection and disinfection by-products in China

Journal of Environmental Sciences, 2019
Disinfection is an indispensable water treatment process for killing harmful pathogens and protecting human health. However, the disinfection has caused significant public concern due to the formation of toxic disinfection by-products (DBPs). Lots of studies on disinfection and DBPs have been performed in the world since 1974.

Disinfection by-products formation during wastewater disinfection with peracetic acid

Desalination, 2007
Abstract Peracetic acid (PAA) is gaining increased acceptance among chlorine-alternative chemical disinfectants claiming that only harmless disinfection by-products (DBPs) have been identified so far, most of them arising from its spontaneous decomposition.
