Nanoplastics (NPs), plastic particles ranging from 1-1000 nm, form through weathering and are considered more hazardous than larger plastics due to their ability to penetrate cell barriers and be internalised by biological systems. Most research on NPs has focused on animal models, examining effects on the brain, lungs, and gastrointestinal tract. To enhance physiological relevance, this study investigated the impact of NPs on human cardiomyocytes (CMs) derived from human embryonic stem cells (hESCs).

Additionally, previously reported species-specific differences in TRPV1 function indicate that use of human SNs is vital for drug candidate screening to have a higher chance of identifying clinically effective TRPV1 antagonists. In this study, we built a histamine-dependent itch model using peripheral SNs derived from human induced pluripotent stem cells (hiPSC-SNs), which provides an accessible source of human SNs for pre-clinical drug screening.

While mechanical circulatory support (MCS) has emerged as a potential intervention, the evidence base for independent MCS use remains weak. In contrast, systematic reviews of observational studies have revealed significant mortality reduction when a combination of MCS was used: VA-ECMO in conjunction with a left ventricular (LV) unloading device (Impella or IABP).

One promising strategy to address these challenges is upcycling, which involves recycling transition metal-based waste from various industries. In this study, a heterostructure electrocatalyst for anion exchange membrane water electrolysis is developed by upcycling iron-based waste from the automotive industry.

However, the complete elimination of all animal-sourced foods from the diet (ie, a vegan diet) may have nutritional ramifications that warrant close examination. Two such concerns are the adequacy and bioavailability of amino acids (AAs) from plant-sourced foods and the consequences for older vegan populations who have elevated AA requirements.
