Intestinal permeability and gene expression after polyethylene and polyamide microplastic ingestion in Wistar rats

Benuarda Toto et al.

Summary: This study investigated the effects of oral ingestion of polyamide and polyethylene particles in rats. The results showed that rats fed with microplastic particles had higher duodenal permeability, and the expression of the tight junction protein gene occludin was higher in the polyethylene group. However, there were no significant changes in the concentrations of tight junction proteins in the gut and plasma.

Lowdensity-microplastics detected in sheep faeces and soil: A case study from the intensive vegetable farming in Southeast Spain

Nicolas Beriot et al.

Summary: The study found that plastic particles were present in both the soil and sheep feces in agricultural fields where plastic mulch is commonly used. Livestock ingest the microplastics found in the soil, and can potentially become a source of microplastic contamination when they graze on other farms. Further research should focus on estimating the direct impact of plastic mulching on the plastic content in animal feces and understanding the potential health effects of plastic residues on livestock.

The impact of polystyrene microplastics on cardiomyocytes pyroptosis through NLRP3/Caspase-1 signaling pathway and oxidative stress in Wistar rats

Jialiu Wei et al.

Summary: The study revealed that exposure to microplastics can damage cardiac structure and function in Wistar rats, leading to oxidative stress, pyroptosis, apoptosis, and activation of inflammasomes in cardiac tissue. These findings suggest that pyroptosis plays a crucial role in microplastic-induced cardiotoxicity and may contribute to understanding the mechanisms of cardiac dysfunction caused by microplastics.

Critical review on microplastics in fecal matter: Research progress, analytical methods and future outlook

Fermin Perez-Guevara et al.

Summary: This review critically summarizes and compares methodologies for determining microplastics in feces and outlines global levels and characteristics of microplastics detected in feces. Despite methodological variations, most studies rely on digestion processes involving H2O2 and KOH, and combining microscopical sorting and spectroscopic methods for identification and characterization of microplastics. The review also identifies analytical challenges and suggests appropriate methods for researching microplastic contamination in feces.

Polystyrene microplastics cause granulosa cells apoptosis and fibrosis in ovary through oxidative stress in rats

Ru An et al.

Summary: The study reveals that polystyrene microplastics have negative effects on rat ovaries by activating the Wnt/β-Catenin signaling pathway, leading to ovarian fibrosis and granulosa cell apoptosis. This ultimately results in decreased ovarian reserve capacity.

Summary: The lack of standardized methodologies in microplastic research has been addressed by this study, which focuses on optimizing the removal of organic matter from wastewater and sludge samples, and targeting the detection of microplastics in sub-hundred-micron size range. The sequential digestion with Fenton reagent represents an inexpensive and time-efficient procedure for wastewater research, allowing for the analysis of large numbers of samples and generation of robust monitoring data sets.

Polystyrene microplastics lead to pyroptosis and apoptosis of ovarian granulosa cells via NLRP3/Caspase-1 signaling pathway in rats

Junyu Hou et al.

Summary: The study showed that exposure to Polystyrene microplastics (PS MPs) could lead to a decrease in the number of growing follicles in rats' ovaries, as well as affecting the oxidative stress response in ovarian tissue. This could trigger pyroptosis and apoptosis of ovarian granulosa cells, potentially impacting female fertility. The findings provide new insights into the toxicity of microplastics on female reproduction.
