Unexpected Exposure Risks to Emerging Aromatic Amine Antioxidants and p-Phenylenediamine Quinones to Residents: Evidence from External and Internal Exposure as Well as Hepatotoxicity Evaluation

Environmental Health
Aromatic amine antioxidants (AAs), extensively used in rubber products, and their ozone-photolyzed product p-phenylenediamine quinones (PPD-Qs) were found to be pervasive in various environments and with potential ecological and health risks.

Evidence for an interplay between cell cycle progression and the initiation of differentiation between life cycle forms of African trypanosomes [PDF]

, 1994
Successful transmission of the African trypanosome between the mammalian host blood-stream and the tsetse fly vector involves dramatic alterations in the parasite's morphology and biochemistry.

The intestinal expulsion of the roundworm Ascaris suum is associated with eosinophils, intra-epithelial T cells and decreased intestinal transit time [PDF]

, 2013
Ascaris lumbricoides remains the most common endoparasite in humans, yet there is still very little information available about the immunological principles of protection, especially those directed against larval stages.

Alpha-tocopherol exerts protective function against the mucotoxicity of particulate matter in amphibian and human goblet cells [PDF]

, 2020
Exposure to particulate matter (PM) in ambient air is known to increase the risk of cardiovascular disorders and mortality. The cytotoxicity of PM is mainly due to the abnormal increase of reactive oxygen species (ROS), which damage cellular components ...

Disruption of the developmental programme of Trypanosoma brucei by genetic ablation of TbZFP1, a differentiation-enriched CCCH protein [PDF]

, 2005
The regulation of differentiation is particularly important in microbial eukaryotes that inhabit multiple environments. The parasite Trypanosoma brucei is an extreme example of this, requiring exquisite gene regulation during transmission from mammals to

Covalent Organic Frameworks for Photocatalytic CO2 Reduction: Metal Integration Principles, Strategies and Functions

Advanced Functional Materials, EarlyView.
Covalent organic frameworks (COFs) with metals have been recognized as versatile platforms for photocatalytic CO2 reduction (CO2PRR). Herein, an overview of metal integration strategies for COFs is systematically summarized. Regulatory mechanisms and structure–activity relationships between metal integration and COF‐based CO2PRR are emphasized.

One‐Pot Amidation/C─H Halogenation by an Efficient Electrochemical Cascade

Angewandte Chemie, EarlyView.
A sustainable electrochemical cascade enables the one‐pot synthesis of regioselectively halogenated N‐aryl amides from readily available amines and acyl halides under mild conditions. The method merges amidation and C─H halogenation in a single operational step, delivering broad substrate scope, high selectivity, and scalability, and provides an ...

Enhanced covalent p-phenylenediamine crosslinked graphene oxide membranes: Towards superior contaminant removal from wastewaters and improved membrane reusability.

Journal of Hazardous Materials, 2019
The increasing depletion of freshwater necessitates the re-use and purification of wastewaters. Among the existing separation membrane materials, graphene oxide (GO) is a promising candidate, owing to its tunable physicochemical properties.
