A Diet High in Fat and Cholesterol Can Lead to Life-threatening Liver Disease

A new study by Keck School of Medicine of USC researchers shows there's yet another reason to avoid high fat, high cholesterol diet: It can trigger changes in the immune system that lead to a serious form of non-alcoholic fatty liver diseases (NAFLD) known as non-alcoholic steatohepatitis (NASH). NAFLD is […]

Mice sleeping fitfully provide clues to insomnia

Mice that sleep fitfully could help researchers unravel the mystery of insomnia. Researchers at Washington University School of Medicine in St. Louis studied mice genetically modified to mimic the genetic disease neurofibromatosis type 1 (NF1), which is associated with sleep problems. They found that the animals, like some people with […]

Racial differences in Alzheimer’s disease unveiled

African-Americans may be twice as likely as Caucasian Americans to develop Alzheimer’s disease, but nobody knows why because studies investigating the underlying causes of illness have historically drawn from a nearly all-white pool of research participants. Consequently, little is known about how the neurodegenerative disease arises and progresses in people […]

Longevity primarily hereditary in extremely long-living families

Longevity is heritable, but that primarily applies to persons from families where multiple members are among the top 10 percent survivors of their birth cohort. The key to a long life can probably be found in the genes of these families. These are the conclusions of researchers at Leiden University […]
