Sustainable Catalyst‐Free PLG Networks: Recyclability, Biodegradability, and Functional Performance

Advanced Functional Materials, EarlyView.
A catalyst‐additive free covalent adaptable network is developed from star‐shaped poly(lactide‐co‐glycolide) cross‐linked with pyromellitic dianhydride, enabling internal carboxylic acid‐driven transesterification. The resulting biodegradable network exhibits mechanical robustness (Young's modulus ≈1.6 GPa), complete recyclability, rapid biodegradation

The physical and Chemical Impact of Microplastic in The Marine Environment: a Systematic Review

Sriwijaya Journal of Environment, 2020
Marine environment reported has been decreasing in water quality caused by microplastic. This micro-particle generated from contamination of ultraviolet light with plastic debris on the environment.

Determination of the gut retention of plastic microbeads and microfibers in goldfish 1 (Carassius auratus) [PDF]

, 2016
Microplastics are ubiquitous pollutants in aquatic habitats and commonly found in the gut contents of fish yet relatively little is known about the retention of these particles by fish.

Characterization of Microplastics in Human Gastric Cancer and Control Tissues and Analysis of Associated Genetic Features

Advanced Healthcare Materials, EarlyView.
This study characterizes the presence of microplastics in human normal gastric, para‐tumor, and gastric tumor tissue and confirms the association between microplastic exposure and lymph node metastasis in gastric cancer. This study explores the transcriptomic changes induced by microplastic exposure, laying the foundation for further investigation into

Unveiling hidden contaminants: a systematic quantification and characterization of microplastics in hemodialysis and peritoneal dialysis fluids

BMC Nephrology
Microplastics (MPs) are an emerging environmental and biomedical concern due to their potential bioaccumulation and toxic effects. Given the extensive exposure of dialysis patients to large volumes of dialysate and water, the presence of MPs in dialysis ...

First Evidence of Potential Microplastic Ingestion of Yellow Striped Goat Fish Upeneus vitattus (Forsskal, 1775) Caught in Malita, Davao Occidental, Philippines

Ilmu Kelautan
Microplastic (MP) study in the Philippines is gaining attention because of the recent trends in macro-microplastic study worldwide and there is already a call for research to help the degrading marine environment in the country. No study in Malita, Davao

The influence of exposure and physiology on microplastic ingestion by the freshwater fish Rutilus rutilus (roach) in the River Thames, UK [PDF]

, 2018
Microplastics are widespread throughout aquatic environments. However, there is currently insufficient understanding of the factors influencing ingestion of microplastics by organisms, especially higher predators such as fish.

3D‐Printed Gastrointestinal Stents: In Vivo Evaluation in a Swine Small Bowel Perforation Model

Advanced Healthcare Materials, EarlyView.
Gastrointestinal fistulae and perforations can lead to severe complications including sepsis and patient death. In this work, the efficacy of 3D‐printed gastrointestinal stents composed of poly‐lactic‐acid (PLA) was evaluated in an in vivo swine model.
