Substances extracted from the Annona squamosa leaf have analgesic and anti-arthritic potential, study reveals

Researchers found that methanolic extract and palmatine from Annona squamosa leaves exhibit analgesic, anti-inflammatory, and anti-hyperalgesic properties. Palmatine may be responsible for the plant's anti-arthritic effects. Further studies are needed to confirm these findings and assess their therapeutic potential.

By looking at individual atoms in tooth enamel, UW and PNNL researchers are learning what happens to our teeth as we age

Researchers at UW and PNNL studied atomic composition of enamel samples from two human teeth, one 22-year-old and one 56-year-old, to understand how enamel changes with age. The study found higher levels of fluoride in the older tooth's shell regions, which could have implications for understanding tooth health as we age.
