Per- and polyfluoroalkyl substances (PFAS) in wastewater streams: occurrence and current treatment

Academia Engineering, 2023
PFAS are a growing environmental concern due to their persistence and universality. PFAS enter the environment through multiple channels, one of which is wastewater.

The minimal probabilistic and quantum finite automata recognizing uncountably many languages with fixed cutpoints

, 2020
It is known that 2-state binary and 3-state unary probabilistic finite automata and 2-state unary quantum finite automata recognize uncountably many languages with cutpoints. These results have been obtained by associating each recognized language with a

Emerging and legacy PFAS and cytokine homeostasis in women of childbearing age

Scientific Reports, 2022
Per- and polyfluoroalkyl substances (PFAS) are widespread chemicals. Legacy PFAS have been phased out of production in most developed countries and emerging PFAS (short-chain PFAS and polyfluorinated compounds) are used as legacy PFAS alternatives.

Early-Life Exposure to Per- and Poly-Fluorinated Alkyl Substances and Growth, Adiposity, and Puberty in Children: A Systematic Review

Frontiers in Endocrinology, 2021
Per- or polyfluoroalkyl substances (PFAS), a family of synthetic polyfluorinated compounds, are widely used in consumer products. Ubiquitous exposures to PFAS, in consideration of their persistence, bioaccumulation potential, and toxicities have led to ...

Adsorption analysis of PFOA on activated carbon and ion-exchange resin: A comparative study using four isotherm models [PDF]

Journal of the Serbian Chemical Society
Per- and polyfluoroalkyl substances (PFAS), known as “forever chemicals”, are highly persistent environmental pollutants due to their strong carbon–fluorine bonds.

Quantification of PFAS in soils treated with biosolids in ten northeastern US farms

Scientific Reports
This study, one of the few conducted to date on working farms in the US, examined per- and polyfluoroalkyl substances (PFAS) contamination in 10 farms treated with biosolids using a paired control-treatment approach.

Adaptaquin is selectively toxic to glioma stem cells through disruption of iron and cholesterol metabolism

Molecular Oncology, EarlyView.
Adaptaquin selectively kills glioma stem cells while sparing differentiated brain cells. Transcriptomic and proteomic analyses show Adaptaquin disrupts iron and cholesterol homeostasis, with iron chelation amplifying cytotoxicity via cholesterol depletion, mitochondrial dysfunction, and elevated reactive oxygen species.
