Tracing tomatoes’ health benefits to gut microbes

Two weeks of eating a diet heavy in tomatoes increased the diversity of gut microbes and altered gut bacteria toward a more favorable profile in young pigs, researchers found. After observing these results with a short-term intervention, the research team plans to progress to similar studies in people.

childhood trauma

Childhood traumas strongly impact both mental and physical health

Lamin C facilitates repair of damaged nuclear envelope in human and mouse cells

Using immunofluorescence and live-cell imaging, researchers were recently able to determine the mechanism underlying the repairing mechanism of the nuclear envelope, which play a key role in various physiologically relevant processes. The accidental rupture of the structure poses a hazard to the integrity of the mammalian nucleus. The study found that lamin C and related factors synergistically facilitate the repair process in mammalian cells.
