New PET tracer detects inflammatory arthritis before symptoms appear

A novel PET imaging technique can noninvasively detect active inflammation in the body before clinical symptoms arise, according to new research. Using a PET tracer that binds to proteins present on activated immune cells, the technique produces images of ongoing inflammation throughout the body, such as rheumatoid arthritis. This makes it easier for physicians to …

Heart organoids simulate pregestational diabetes-induced congenital heart disease

An advanced human heart organoid system can be used to model embryonic heart development under pregestational diabetes-like conditions, researchers report. The organoids recapitulate hallmarks of pregestational diabetes-induced congenital heart disease found in mice and humans. The findings also showed that endoplasmic reticulum (ER) stress and lipid imbalance are critical factors contributing to these disorders, which …

A new ‘metal swap’ method for creating lateral heterostructures of 2D materials

Heterostructures of two-dimensional materials have unique properties. Among them, lateral heterostructures, which can be used to make electronic devices, are challenging to synthesize. To address this, researchers used a new transmetallation technique to fabricate heterostructures with in-plane heterojunctions using Zn3BHT coordination nanosheet. This simple and powerful method enables the fabrication of ultrathin electronic devices for …
