New imaging technology shown to detect pancreatic inflammation in type 1 diabetes

...ill into nearby tissues, where they are "eaten" by scavenger cells called macrophages. Thus, the MNPs become concentrated at the inflamed site and can be spotted by high-resolution MRI. In their recent study, the researchers applied the MRI-MNP technique to determine whether they could predict which mice wou...

Genome of Clostridium botulinum reveals the background to world's deadliest toxin

...iotics. It lives either as a dormant spore or as a scavenger of decaying animal materials in the soil, and doesn’t interact with human or other large animal hosts for prolonged periods of time. Occasionally it gets into a living animal, via contaminated food or open wounds, leading to infant botulism or wou...
