Enhanced Degradation of Vinyl Copolymers Based on Lipoic Acid

Journal of Polymer Science, Volume 63, Issue 6, Page 1345-1351, 15 March 2025.
ABSTRACT The introduction of degradable units into the backbone of commodity vinyl polymers represents a major opportunity to address the societal challenge of plastic waste and polymer recycling. Previously, we reported the facile copolymerization of α‐lipoic acid derivatives containing 1,2‐dithiolane rings with vinyl monomers leading to the ...

Evaluation of Concordance between Radiation Therapists and Medical Physicists in MR‐Guided Online Adaptive Planning

Precision Radiation Oncology, EarlyView.
Magnetic resonance (MR)‐guided online adaptive radiotherapy requires skill in online adaptive treatment planning. This study demonstrated that radiation therapists, with appropriate training, can consistently produce high‐quality adaptive plans concordant with those created by medical physicists for treatment on a 1.5 Tesla MR‐Linac.

Heterogeneity Index of Trade and Actual Heterogeneity Index – the case of maximum residue levels (MRLs) for pesticides [PDF]

Non-tariff measures (NTMs) beyond traditional trade policy instruments define the requirements that importing countries imposed on foreign products. Due to differences across countries, requirements for supplying foreign markets can lead to trade costs ...

The 5T Paradox of Triclosan: From Toiletries to Toxic Trash, a Growing Threat to Humanity

Environmental Toxicology, EarlyView.
ABSTRACT Triclosan (TCS) persists as a contaminant of concern in the Anthropocene, despite regulatory actions. Environmental dissemination continues through wastewater effluents, biosolid application, and improper disposal practices. This narrative review synthesizes current evidence regarding triclosan's environmental fate, transformation pathways ...

Assessment of Metal Contamination and Human Health Risk in the Buffalo River Estuary, Eastern Cape, South Africa

Environmental Toxicology, EarlyView.
ABSTRACT Metal contamination in estuarine environments poses environmental and public health concerns, particularly where surface waters support domestic and subsistence uses. This study assessed the seasonal distribution, controlling mechanisms, and non‐carcinogenic health risks of selected metals (Mg, Al, Ba, Fe, Mn, and Zn) in the Buffalo River ...

Quantifying the impact of phytosanitary standards with specific reference to MRLs on the trade flow of South African avocados to the EU [PDF]

, 2017
In this study a gravity model was used to investigate the impact of country specific MRLs that are more stringent than the MRLs set by CODEX on avocado exports by South Africa to the EU with specific reference to Prochloraz. The results revealed that the

Voluntary consumption of cyclophosphamide by Mrl mice

Brain, Behavior, and Immunity, 1989
Fluid-deprived, lupus-prone Mrl-lpr/lpr and congenic Mrl +/+ mice were provided with a single drinking bottle containing varying concentrations of cyclophosphamide (CY) dissolved in chocolate milk. Eighteen- and 20-week-old Mrl-lpr/lpr males with manifest symptoms of autoimmune disease voluntarily consumed more of the CY solution than Mrl +/+ mice of ...
