Tau-protein better predicts brain atrophy in Alzheimer's patients than amyloid plaques

Brain imaging of pathological tau-protein "tangles" reliably predicts the location of future brain atrophy in Alzheimer's patients a year or more in advance, according to a new study by scientists at the UC San Francisco Memory and Aging Center. In contrast, the location of amyloid "plaques," which have been the focus of Alzheimer's research and drug development for decades, was found to be of little utility in predicting how damage would unfold as the disease progressed.

New trial shows how parents can avoid bringing dangerous bacteria into the NICU

For sick or prematurely born babies spending their first days of life in a hospital's neonatal intensive care unit, the soothing voice and gentle touch of a loving parent can have a tremendous impact toward a positive outcome -- that is, unless mom or dad's visit leaves the infant with something extra: a dangerous bacterial infection.

Bile acids help norovirus to infect cells of the small intestine

A new study led by researchers at Baylor College of Medicine and published in the Proceedings of the National Academy of Sciences reveals that human noroviruses, the leading viral cause of foodborne illness and acute diarrhea around the world, infect cells of the small intestine by piggybacking on a normal cellular process called endocytosis that cells use to acquire materials from their environment.

Obj-SCD predicts future amyloid accumulation and neurodegeneration

Writing in the December 30, 2019 online issue of Neurology, researchers at University of California San Diego School of Medicine and Veterans Affairs San Diego Healthcare System report that accumulating amyloid -- an abnormal protein linked to neurodegenerative conditions such as Alzheimer's disease -- occurred faster among persons deemed to have "objectively-defined subtle cognitive difficulties" (Obj-SCD) than among persons considered to be "cognitively normal."
