A new study from University of Alberta researchers has shown that traumatic or stressful events in childhood may lead to tiny changes in key brain structures that can now be identified decades later.
A team of researchers from the Laboratory of Biophysics at NUST MISIS, Lomonosov Moscow State University and D. Mendeleev University of Chemical Technology of Russia has summarized metal-containing diagnostic agents for positron emission tomography (PET), magnetic resonance imaging (MRI), and single-photon emission computed tomography (SPECT) imaging of Alzheimer s disease (AD). According to the researchers, their use could improve access to diagnostic imaging of AD among the risk groups.

A new study of autism risk genes by UC San Francisco and UC Berkeley scientists implicates disruption in prenatal neurogenesis - a process in which specialized progenitor cells give rise to new brain cells - in the development of autism spectrum disorders (ASDs). The study also shows that estrogen, perhaps in a form produced within brain cells, can protect against this disruption and steer the brain on a normal course of development.
The most striking findings in the study, published on January 25, 2021 in
Neuron, were derived from experiments using embryos of the western clawed frog (Xenopus tropicalis), a species prized by biologists for the unique insights it offers into development. Human genes involved in development have counterparts with similar functions in Xenopus, and extensive studies correlating human embryonic stages with those of the frog mean that genetic studies in Xenopus can have direct relevance to human development in both health and disease.

East Hanover, NJ. February 8, 2021 - Kessler Foundation researchers have received support from Genentech, a member of the Roche Group, to conduct an investigator-initiated study on the effects of ocrelizumab (Ocrevus) on cognitive fatigue in individuals with relapsing-remitting multiple sclerosis (MS).
John DeLuca, PhD, senior vice president of Research and Training, is principal investigator for the study titled, A Biomarker for Cognitive Fatigue in MS using Functional Imaging . The study team includes Glenn Wylie, DPhil, director of the Rocco Ortenzio Neuroimaging Center at Kessler Foundation, Ekaterina Dobryakova, PhD, research scientist in the Center for Traumatic Brain Injury Research, and Helen Genova, PhD, assistant d
Higher blood pressure at night than in daytime may be a risk factor for Alzheimer s disease in older men. This is suggested by a new study from researchers at Uppsala University, now published in the journal
