Bile acid from gut microbes disrupts blood stem cells in mice

In mouse experiments, prolonged exposure to a gut microbial bile acid contributed to blood stem cell loss, while a high-fiber diet reduced age-associated decline.In mouse experiments, prolonged exposure to a gut microbial bile acid contributed to blood stem cell loss, while a high-fiber diet reduced age-associated decline.

Nicotinamide mononucleotide reduced lens stiffness in mice

Lens stiffness measured 11.9 kilopascals at the higher dose, versus 17.9 in mice with diet-induced metabolic syndrome given no active compound.Lens stiffness measured 11.9 kilopascals at the higher dose, versus 17.9 in mice with diet-induced metabolic syndrome given no active compound.
