Microplastics in the Food Chain
Life, 2021 Currently, microplastics represent a widespread contamination found in almost every part of the environment. The plastic industry has generated waste since the 1950s, which unfortunately now counts in the millions.

Co-contaminants of microplastics in two seabird species from the Canadian Arctic
Environmental Science and Ecotechnology, 2022 Through ingestion and subsequent egestion, Arctic seabirds can bioaccumulate microplastics at and around their colony breeding sites. While microplastics in Arctic seabirds have been well documented, it is not yet understood to what extent these ...

Environmental status of (micro)plastics contamination in Portugal
Ecotoxicology and Environmental Safety, 2020 Plastics and microplastics are ubiquitous contaminants in aquatic ecosystems. This critical review is the first attempt at analyzing sources, concentration, impacts and solutions of (micro)plastic litter in Portugal based on all currently available literature. We found that, besides sea-based sources (e.g. shipping, fishing), 5717 t of mismanaged waste

Vision-Transformer Model Validation Image Dataset
AgriEngineeringThe removal of plastic contamination from cotton lint is a critical issue for the U.S. cotton industry. One primary source of this contamination is the plastic wrap used on cotton modules by John Deere round module harvesters. Despite rigorous efforts by

The Practices and Attitudes of Saudi Plastic Surgeons in Managing Contaminated Autologous Grafts
Plastic and Reconstructive Surgery, Global Open, 2022 Background:. The use of autologous grafts is a standard reconstructive option in plastic surgery. The absence of a well-established protocol for decontamination after accidental contamination increases the risk of postoperative infection.

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Molecular Oncology, EarlyView.Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Towards the Rational Use of Plastic Packaging to Reduce Microplastic Pollution: A Mini Review
Journal of Marine Science and EngineeringPlastic pollution has been recognized as an emerging risk for the aquatic environment. Shifting from the prevailing linear “take-make-dispose” model to a “circular” economy framework is essential for mitigating the environmental impact of plastics ...
