Microplastics in human skeletal tissues: Presence, distribution and health implications.

Although microplastics have been detected in human blood, placenta and other tissues. In this study, for the first time, we characterized the presence and variation of microplastic deposition patterns in three human skeletal tissues, namely the bone, cartilage, and intervertebral discs. Forty microplastic fragments were observed in 24 samples from the bone, cartilage, and intervertebral disc, ranging from 25.

Engineering a high-yield glutathione strain of Hansenula polymorpha using ion beam implantation.

To generate an industrial strain of Hansenula polymorpha capable of yielding greater levels of glutathione (GSH), wild strain H. polymorpha DL-1 cells were mutated using a nitrogen ion beam, a novel mutagen. At an energy level of 20 keV and dose of 2.
