Currently, the increasing use of nickel metal-organic frameworks (Ni-MOF) and nickel oxide nanoparticles (NiO NPs) has raised concerns regarding their potential environmental impact on wastewater treatment systems. Herein, the responses of aerobic granular sludge (AGS) and algal-bacterial aerobic granular sludge (AB-AGS) to Ni-MOF and NiO NPs were investigated. The results showed that Ni-MOF concentrations of 50, 100, and 200 mg/L significantly reduced nutrient removal in both systems, particularly affecting ammonia, nitrite, and phosphorus removal, while denitrification processes remained stable.

- The study evaluated the impact of varying concentrations of titanium dioxide nanoparticles (TiO NPs) on two types of sludge: aerobic granular sludge (AGS) and algal-bacterial granular sludge (ABGS) over a 10-day period in synthetic wastewater.
- At lower concentrations (1 and 5 mg/L), TiO NPs did not significantly affect nutrient removal but increased the production of extracellular polymeric substances (EPSs), particularly proteins.
- Higher concentrations (up to 50 mg/L) negatively impacted nutrient removal, especially in AGS, while ABGS showed greater resilience due to its higher microbial activity and symbiotic relationships between algae and bacteria.
Evaluation of nasal mucociliary clearance in patients with psoriasis.

Purpose: Psoriasis is an autoimmune pathology characterized by chronic inflammation with known multiorgan involvement. In the literature, there are few studies investigating the effects of psoriasis on upper respiratory tract mucosa. Our aim in our study was to investigate the possible effect of psoriasis disease severity and duration on nasal mucosa.
View Article and Find Full Text PDFTitanium dioxide nanoparticles (TiO NPs) are extensively used in various fields and can consequently be detected in wastewater, making it necessary to study their potential impacts on biological wastewater treatment processes. In this study, the shock-load impacts of TiO NPs were investigated at concentrations ranging between 1 and 200 mg L on nutrient removal, extracellular polymeric substances (EPSs), microbial activity in aerobic granular sludge (AGS), and algal-bacterial granular sludge (AB-AGS) bioreactors. The results indicated that low concentration (≤10 mg L) TiO NPs had no effect on microbial activity or the removal of chemical oxygen demand (COD), nitrogen, and phosphorus, due to the increased production of extracellular polymeric substances (EPSs) in the sludge.
