Pre-eclampsia (PE), a hypertensive disorder during pregnancy, impairs maternal endothelial function, leading to inflammation and oxidative stress that may increase the risk of severe brain conditions like stroke. This study investigated whether a history of PE causes long-term vascular dysfunction and worsens stroke outcomes during the postpartum period in rats. The findings reveal persistent effects of PE on the maternal brain and offer insights into the underlying mechanisms driving these adverse outcomes.

Nowadays, plastic wastes have seriously endangered human health and ecological safety. Recycling plastics is a promising ap-proach to achieve multiple uses of carbon resources. In this review, photocatalysis is introduced for the conversion of plastics into various valuable chemicals. The state-of-the-art photocatalytic techniques for plastics conversion are divided into two categories of direct and indirect photoconversion. Researchers summarize in detail the photocatalytic small organic molecules conversion from polyeth-ylene terephthalate (PET), polylactic acid (PLA) and polyethylene (PE) through the alkaline-assistant and hydrothermal pretreat-ments. Then, they overview the effective strategies of direct photoconverting PE, PLA and polyvinyl chloride into chemicals via the two-step process, amination strategy, and single reactive oxygen species-assistant strategy. Finally, they present some outlooks of the current challenges and propose some potential solutions in the future.
