ClearInternalized polystyrene nanoplastics trigger testicular damage and promote ferroptosis via CISD1 downregulation in mouse spermatocyte
Researchers found that polystyrene nanoplastics cause testicular damage in mice through a cell death process called ferroptosis. The nanoplastics triggered the breakdown of iron-storage proteins and reduced levels of a protective mitochondrial protein called CISD1 in sperm cells. The study suggests that nanoplastic exposure may contribute to male reproductive harm by driving excess iron into mitochondria.
Glycine alleviates ovarian granulosa cell ferroptosis induced by ERα-mediated internalization of polystyrene microplastics
Researchers found that polystyrene microplastic exposure in mice triggers ferroptosis (iron-mediated cell death) in ovarian granulosa cells via ERα-mediated internalization and YAP1-ACSL4 signaling, and demonstrated that the amino acid glycine can restore iron homeostasis and alleviate this reproductive toxicity.
Utilizing biofilm-enhanced coconut coir for microplastic removal in wastewater
Researchers found that coating coconut coir (a natural fiber) with biofilm — communities of microorganisms — boosted its ability to capture microplastics from wastewater, achieving 85–95% removal efficiency compared to 72–82% without biofilm. This low-cost, natural approach offers a promising sustainable filter material for tackling microplastic pollution in water treatment systems.
Cellulose-Based Sorbents: A Comprehensive Review of Current Advances in Water Remediation and Future Prospects
This review examines advances in cellulose-based sorbent materials for removing heavy metals and organic pollutants from wastewater. The study highlights that various modification methods such as carboxylation, amination, and oxidation can enhance cellulose's sorption capacity, making it a promising biodegradable alternative for sustainable water treatment technologies.
МОДИФИЦИРУЮЩИЙ ЭФФЕКТ ПРОДУКТОВ ПЕРЕРАБОТКИ ОТХОДОВ НЕФТЕХИМИИ В ПРОЦЕССАХ СМАЧИВАНИЯ И СТАБИЛИЗАЦИИ ТВЕРДОФАЗНЫХ ЧАСТИЦ
This Russian-language study examined how petrochemical waste products can modify wetting and surface stabilisation processes for solid particles in coatings and paint applications. The research explores using recycled industrial byproducts as functional coating additives.
